Going to start building my car looking for input

[rx7mechusa]

Ok im looking to build up my car some to make a fun weekend car out of nothing overly incredable and im wanting to push 300-325 hp total wanting some input on the parts im g2 use and recomendations for the parts i havnt located or things you see im not doing right.

Engine-
radiator- Koyo R-core
turbo- Garret GT35R
intercooler- HKS type-s front mount
downpipe- HKS
bov- HKS SSQV
intake- HKS filter on TID i made a while back
ecu- Halteck E8K plug an play for S4 from mazdatrix / any suggestions here? not sure what i want to do here was also wonding how far i can go on stock ecu and fuel i assued 250hp was max on stock ecu and fuel but am not sure.
fuel- again not sure here pump for sure but can i get to 300 on the stock inj?

Exhaust-Apexi GT-Spec

Suspension-
coilover- Tein Flex
bushings- not sure who to get from would like some recomendations

Drivetrain-
clutch- ACT

Electronics / Gauges
boost - HKS
boost controller- HKS
water temp- HKS
A/F R- Innovative (LC-1 harness and gauge)

This is what ive got so far any and all comments changes and recomendations and anything you think i should be looking at and am not please tell me.

[djmtsu]

Sounds good Josh. You and I have nearly the same goals in mind, albeit with different brands! Lol.

[djmtsu]

PS- I'm stealing those wheels.

[rx7mechusa]

haha if i ever decide to take'em off you got first dibs on'em if you still want'em

[RETed]

It sounds like you're too stuck on using prefab'd parts...
If I were you, I would get over trying to buy stuff over the counter.
Yeah, it's nice to brag you're using this and using that, but you're just making things harder on yourself on this build.

1) That HKS downpipe is not going to bolt onto the GT35R.

2) I dunno what a "E8K" is?

3) Stock injectors will not support 300hp.

4) Stock ECU is just about it's limit at the 300hp - 325hp level you're looking at, but couple the stock ECU with an S-AFC device can work (with larger fuel injectors).

5) Don't bother with the APEX'i exhaust - it's necked down to 65mm in the front to mount with the stock exhaust; you're choking your exhaust system.
If you insist on the A'PEXi N1 muffler look, just buy the muffler - get a custom 3" exhaust build from your local muffler shop.
At the same time, have the muffler shop make you a custom downpipe insteading of modifying that HKS downpipe, cause you're going to need it to fit with the GT35R.

Do you actually have these components?
A lot of stuff is big bucks - i.e. HKS, Koyo - so if you already have it, I can understand.
Those eBay IC cores are cheaper (sometimes under $100) and do just as well, if not better than, that HKS Type-S IC.

If you do go with the Haltech, who is going to tune it?
Are you going to haul the car to some tuner to have them tune it for you?

Ok ted i have alot of the stuff already and as a note im deployed to afgan at the moment so money isnt that big of an issue atm. Exhaust came with the car, gauges, boots controller, koyo rad, Tein coilovers are waiting on me to get home. Only thing's i havnt bought yet are the turbo, manifold, injectors, FMIC and ECU couldnt decide if a true stand alone was needed or just a fuel piggy back system. Yes i realize alot is just bolt on parts and as for tuning the haltec i honetly am not sure yet. I want to have it tuned at a shop first then learning the basic's of using the software and what all is required to do some tuning myself. As for modifying the downpipe it wont be an issue i have a few budies that work in the machine shop on the base (made my block off plates for me) that can help me fab whatever will be needed. What injectors do you recomend and what ecu setup would you recomend? Also the turbo is fairly expensive so im waiting on that one until i get home in Dec so i have alot of time to plan for exhaust issues and my plan was once the GT35 is in to run a true 3in exhaust 275-325 is my goal for HP now that ive been looking more at how much ill actually be driving the car

[rx7mechusa]

as far as moving my car around its no issue i have a car trailer and a suburban that i use to move when the army decides its time for me to PCS

[rx7mechusa]

Ok figured out how i want to do the GT35R with downpipe taken care of A-Spec GT35R T4 kit and once that comes in ill custom the exhaust minus the N1 muffler from the apexi GT spec thats on the car now. Still not sure how to go about the fuel yet bosch 044 fuel pump and im looking for rails and injectors now. any thoughts on this and ecu?

[RETed]

Okay, you can use most of the A'PEXi exhaust, but you need to hack the front part of it off.
Like I said before, it's a 65mm flange in front to mate with the stock catalyic converter (exit).
65mm is smaller than 3".
With the GT35R, a 3" exhaust is recommended minimum.

Fuel injectors...
1600's used to be popular, but I haven't seen them recently?
Anyone can help with this?
The Haltech has no problem firing 550 stock primaries and 1600 secondaries.
550 + 1600 is good enough for 400 no problem.

Stock fuel rails not a problem.
They will handle 400 no problem.
You'd need to worry if you're going for 500.
If you're looking for something to modify, you can convert the rail to parallel flow and run an aftermarket FPR like SX or Aeromotive.

This is not cheap!

Good luck and stay safe over there!


-Ted

[rx7mechusa]

Ok ill keep that in mind about the apexi exhaust and once i can get under the car again ill look to see how it'll fit and were i need to hack it off at. Ill start looking around for some 1600's. what is the max i can get to on stock injectors until i can locate some better ones? say 225-250 ish? again i am only shooting for 300 and was also wondering about doing a greddy intercooler pipe kit and using a regular IC? what do you think of that?

[project86]

have you actually heard that muffler yet? cause i think they should call it something different than a "muffler" haha. i have an N1 and expect loud.. and i mean loud. maybe not as bad for you cause the turbo is gonna kil some of the noise but just a thought to think on :)

[rx7mechusa]

haha noise isnt an issue for me i work on helicopters im deaf anyways :D How would the Rtek and duel 720's work for 300hp?

[rx7mechusa]

Ok been doing some research and ive decided that i am probably going to go with the Haltech PS1000. as for inj probably 550/720 to start out with.

[RETed]

Check out the rx7.com fuel injector calculator here:
http://rx7.com/cgi-local/2ndgencalc.cgi

Keep in mind that the resulting numbers are BHP FLYWHEEL HP numbers.
Knock off 15% for most DynoJet numbers.

550 + 720 will get you maybe 250hp at the rear wheels.

I dunno where you can get just the GReddy IC pipes?
GReddy only sells full kits.
You might get lucky finding someone parting their kit though...


-Ted

[rx7mechusa]

Thanks alot Ted for that calculator how hard do you think this set up 550cc primary 1600cc secondary (as you mentioned before) on a Haltech PS1000. I actually found a couple of sites that will sell just the elbow and pipes but i found a reasonably priced HKS one today that im g2 pick up. Who makes good 1600cc injectors? I read some stuff on the "other" fourm today about marren (not sure thats exactly right) i have changed the build some in other ways aswell talking with my buddies in the machine shop here they say modifing the apexi exhaust to become a true 3in wont be a problem. Also what fuel pump do u recomend ive read good reviews about a few bosch 044, walboro 255, and one on rx7.com

[RETed]

I don't have any direct experience with the PS-series that just came out.
I've done older E6K and the previous E8 / E11 stuff.
If the PS-series is anything like the previous mentioned ECU's, it'll have no problem running those 1600's.

BTW, the "1600" fuel injectors are Bosch / Ford 160 lbs./min "LPG" fuel injectors that are easily adapted for our engines.

I prefer the "Supra TT" NipponDenso fuel pump for 400hp levels.
These are drop-in replacements for stock.

The Bosch -044 is another good fuel pump, but the (inlet) fitting makes it difficult for an easy install.
You need a prefilter for the fuel pump inlet, and Bosch does not furnish them.
I've seen a website that offers a dinky prefilter for use on the -044, but this is the main reason why I prefer the SupraTT fuel pump over this -044 unit.

Walbro 255lph is last recommended.
It does the job, but reliability is spotty.
On top of everything else, there are conterfeits out there.
The ND and Bosch units above are a lot more reliable than the Walbro.
The Walbro is cheap though - usually right around $100.

Ok ill start hunting a Supra TT and what do i half to modify to make the ford 1600's fit or will they go in without having to be tampered with? Also the haltech offers it own wideband afr stuff would recomend using the haltech instead of the innovative? Thanks for all the info also Ted its covering some things i hadnt thought of yet. Ted do you know of a website that sells them or one of our own vendors that may have the injectors?

[rx7mechusa]

Also should all four injectors be Low Imp.? if im not mistaken the late 88's (not sure if this includes the 10th AE) had High Imp. 550's or will them being different make any difference?

you could maybe check on gettin a cosmo fuel pump too... corksport sells them

[RETed]

Looks like eBay has several vendors that do sell the 1600's.
These Ford / Chrysler 1600's need to be modified to fit the FC fuel rails.
The evil forum had instructions to do this.
Do we have one on this forum?

I bought my SupraTT fuel pump from eBay.
It was a little less than $200.
That's cheap for this fuel pump.

HKS used to sell that (inferior) Cosmo fuel pump for over $300!
Last time I checked, most places price the Cosmo fuel pump MORE than the SupraTT fuel pump.

The SupraTT fuel pump flows more.

I don't believe in widebands.
I'm the last person to be asking about widebands.

Fuel injector impedence doesn't matter if you're going Haltech.
The Haltech will control either high or low impedence fuel injectors.
The stock fuel injectors off of a 1988 FC is all high impedence.
Mazda changed from low to high in mid-year 1987.


-Ted

[djmtsu]

Josh, if you are looking at only hitting 300ish, why not go with a BNR?

I know Ted and alot of people are not fans of hybrids, but I have experienced them in both FC's and FD's and they work great for the power levels you want. Also, no need for a custom downpipe or manifold.

Just a thought, that is where I am headed. And Paul (Fero313) lucked out an got a Knightsports T4 hybrid on his engine for the vert.

[rx7mechusa]

Ill keep it in mind and look at the BNR's tonight. Ted i found the supra pump for 225 shiped to the house on ebay so probably g2 do that. Still looking around at injectors and am going to start looking for a S5 throttle body with TPS sensor so if you have on DJ or know were ones at let me know g2 swap it out from the S4 one on my car.

[rx7mechusa]

you are bidding on 1 brand new DENSO fuel pump upgrade for the 1993-98 Toyota Supra Turbo & Mazda RX7 twinturbo.

This is a direct replacement pump for the supra and a great upgrade for many other cars like the Mazda RX-7, SW20 Toyota MR2, Eclipse turbo, etc....

DENSO reliability & quality. Dont go cheap on your fuel system with those noisy intank 'wallybros'. There is a reason why Toyota uses DENSO pumps in the Supra to make sure there will always be enough fuel! Densos are QUIETER & MORE RELIABLE!

flows 280 LPH -
BEST IN TANK FUEL PUMP UPGRADE FOR THE SUPRA AND WORKS GREAT FOR ALL SORTS OF HIGH POWER APPLICATIONS!

Does this sound right before i buy it Ted? its not bad priced and i think would serve fine. also im going to recompile my build up stuff tomorrow and see what you think. Any recomendations on rebuilds? My eng is good but it will need a rebuild or replacement before i start upgrading to much ie the GT35

[RETed]

Yep, sounds like the one.
Try and get the part number...
It should be: 195130-1020

As for hybrid turbos...
I actually like them.
I run them on my FC.
They are easy to install.
They can make lots of power.
If you can afford a full turbo upgrade, I will always recommend that route.
The stock turbo turbine section is too small when you compare them with full (T04) turbine sections.
The full turbo upgrade will almost always flow more efficiently.


-Ted

[rx7mechusa]

Engine: L6 (3.0L)
ID: 2JZGTE
PN: 950-0155
(Mounting Kit) (2JZGTE Eng.) w/ Turbo; DENSO Manufactured OE / OES Service Part Replacement Fuel Pump & Strainer Kit

That is the part number and description i found on the ebay page and it had a link to Denso's website to verify it if you think is right thing im going to go ahead and buy it Ted.
I have the money for the A-Spec kit the non bb one GT3574 so i want to use that but its more than i think i need for 300-325hp is 350-375hp still an ok set and drive it alot?

[RETed]

http://forums.celicasupra.com/archive/index.php/t-41814.html
Looks like it's the right part...

I always recommend to go bigger, especially if you're not shooting for 400. :)
(You're going to want to!)
With a bigger turbo (than what you need), you can always run lower boost.
Running lower boost puts less stress on the engine.


-Ted

[rx7mechusa]

Been looking on the A-Spec fourm on the other site and it seems i can get my 300hp to the wheels at about 12psi so im going to probably have it tuned to get something like that out of the car. 12psi on a rebuild T2 motor dosent seem that bad to me. going to work out what im going to put on the car and post it up in a lil bit. Do you think the stock FPR can handle this on the A-Spec site the car that was actually running that tune still was using the stock one that safe or should i consider upgrading it here since im working on the fuel system anyways.

[RETed]

Stock FPR is good to 400hp - that's my rule of thumb.
I don't change it out until you start getting to 500hp - that's my rule of thumb.


-Ted

[rx7mechusa]

Ok Ted sounds good to me as im lookin at that car i think ill be running 8-9psi in my car should be all i need. I am looking into some suspension stuff now i had originaly put a set of Tein Flex on order but i cancel'd them because i found a better price on them on another website also was wondering what everyone thinks of Ksport, Tein, Cusco

[rx7mechusa]

Wondering about using FMIC vs Upgraded TMIC i found an ARC TMIC for a fairly good price wondering if this would work with the hp im trying to get to?

[Flooder]

550/1600 seems like a huge difference. Wouldn't the transition be really rough?

I've got a pair of 680cc injectors and a pair of 1000cc injectors for sale if you're interested :).

[RETed]

550/1600 seems like a huge difference. Wouldn't the transition be really rough?

Haltech has no problem handling it.
In fact, majority of Haltechs run this combo.
I know Microtech used to have a problem firing this combo.


-Ted

[RETed]

Wondering about using FMIC vs Upgraded TMIC i found an ARC TMIC for a fairly good price wondering if this would work with the hp im trying to get to?

Personally, TMIC is a waste of time.
The FMIC is always superior with the exception of cost and complexity of the install.
With the $100 eBay cores (bar-n-plate), it's cheap enough almost every FC owner can afford it; the hard part is the pipes and the throttle body adapter.

Almost anything out there (from Japan) is okay.
I like Tein and Cusco myself
Most street driven cars don't need all the fancy adjustments most of those systems offer - it's a waste of money.
Tokico Blues + aftermarket springs are usually fine for most applications.

Personally, I like Koni dampers with custom housings for the FC.
(Koni is made in Europe - not Japan.)
Koni yellows offer great adjustment (continuously variable - not detents; not necessarily good for beginners) and can be custom valved if need be (for serious racing) - this is overkill for the street.

Cheap adjustable are KYB AGX's (great for the money + adjustment).

Retrofit coilovers are offered by Ground Control.
You can run whatever spring rate you want to custom your ride height.

[rx7mechusa]

Awsome thanks i have the greddy elbow and pipes at the house just would need to spruce them up a bit and i have another interesting problem i want to keep my P/S and A/C as this is not in any way shape or form going to be a "race" car. And i think if im creative enough i can run the pipes to allow this but has it been done? Thanks for the info on the suspension as well Ted.

[MaczPayne]

It can be done, you'll have to use a little ingenuity in the routing. The older HKS and Trust FMIC's were routed so that you were able to retain both A/C and P/S

[Flooder]

You can do it, its just all custom work. You might as well do a v-mount setup at that point for better cooling and less turbo lag.
