FC Zach's '87 Sport

[FC Zach]

If you have met me or seen my 7 at DGRR/B3R then you probably noticed it's carbed and if you know me personally then you have probably heard me whine about it at one point or another. Years ago (many) I wanted to be different with my 2nd Gen, so I stripped the engine bay down to have nothing I didn't need and have just what I did need. I love simplicity and wanted it to be basic. When I first installed the RB Holley kit I loved it, it did what I wanted it to do and I was happy with it until it got to the point where I overcomplicated what should be a simple set up. Eventually it got to the point where I hated the Holley carb and the constant adjustments that were required to get it to run ok at best.

The last straw was on the way to B3R last year when I barely made it up a hill because the engine loaded up with sooooo much fuel that it nearly died (this has happened way too many times before this incident). I lost my temper to say the least and placed parts orders as soon as I figured out what I wanted to do and where to get the parts.

I wanted to retain the simplistic aesthetics that I've always had with my engine bay and to do this I decided I would keep the intake manifold and use a proper sized throttle body and also by removing the distributor and replacing it with a trigger wheel along with a slimmer coil design that's more up to date than what I had been using.

Here is an old pic from many years ago, this is the old set up.


The first major purchase was the throttle body. After years of searching, looking for a throttle body that wasn't too big, I finally made my decision. I chose an efi Hardware 700cfm throttle body. Thing sure is a work of art, it has ball bearing shafts and a smooth CNC machined finish. It's also nice that the TPS is an easily sourced GM part.


I chose to run a Sprint RE ecu to control everything, I was amazed by how small this thing is. Will be mounted in a gutted OE ecu.


I wanted a more accurate measurement for oil pressure/temp as well as air/fuel, so with the help of Ludwig I chose these Defi gauges and a Haltech wideband controller. The Defi gauges will also be used to monitor fuel pressure/water temp via switches (as soon as I figure out how to do so).


I had to purchase a filter pedestal in order to install pressure/temp sensors.


I eventually want to run a cold air intake so I searched for an undivided carb bonnet. Maybe even a turbo one day


Completely changed fuel setup.

New injectors, went with Bosch EV14s.


For the ignition I chose to use the FFE trigger wheel over OEM CAS.


Coils will be the IGN-1As, I originally planned on mounting them with the use of this SakeBomb universal mounting kit but that was until I saw RiceRacing designing a true COP design with use of these coils. Sold the SB kit and now anxiously waiting on the RR kit



While I was changing things I wanted a more efficient cooling fan and a better mount for it so I had a local fabricator make a shroud for my new fan.



That's it for now. . I'm waiting on delivery of the new coil mount and I have Ludwig making a harness for me, as soon as these arrive I can start assembling everything and assuming there are no issues with anything I'll have (hopefully) enough time to get the car on the dyno for some tuning to be ready for DGRR. Crossing fingers and hoping for the best. worse case scenario I'll drive the daily.

Looks good man...... I've been wanting to do something differnt on the track car like get rid of the Weber and do a ITB setup but money problems.

[FerociousP]

I'll do my best to help Zach. I've got three projects i'm involved with, two are going to DGRR, but I'd love for yours to make it... even if we need to do tuning on the way there I should have some sprintRE maps that you can use/modify to simplify tuning.

[almoststockfc]

Looking good man!!

[FC Zach]

Thanks guys! I hope it makes it but if it takes rushing it then I think it would be best to drive the celica, we'll see.

[t_g_farrell]

If the RR kit doesn't make it in time, you can always rig up some coils just to run
the leading spark (who needs trailing anyway ) Look forward to seeing it.

That RR setup is sweet, I wonder of it will work on a 12A? I know there would be some
size differences due to the housing widths. Never got an answer on that in the thread
he had on it.

Looks GREAT Zach! Can't wait to see her this year The only thing I would change would be the fuel return line.... I would flip it 180* and run it on top of the intake as opposed to on top of the exhaust...

And screw the dyno if you can't make it.. ROAD TUNE!!! You get MUCH better driveability when tuning on the road than on the Dyno..... dyno is great for WOT but for the nitty gritty stuff... road tuning is where it's at. Ask MC about the difference between the first go around and the second when I spent a few hours driving back and forth tuning the low load cruising and transition. He actually liked it better the first time, it was much more violent as opposed to now he says it drives like a stock car until you mash the go-pedal. As a tuner that what I was looking for... I guess MC liked breaking the tires loose at 65 on the highway

That's what I'm fucking talking about!

DON'T DO IT!!!

Rice's latest posts seem to suggest he's not going to offer the IGN-1A stuff. I need to message him to see what's up.

I love the setup. The similarities in our builds is pretty uncanny. Would have been even more so if I didn't start going crazy. But then again, that ended up benefiting you

This look better?

I would, he may work with you. . It definitely wont hurt.

Ha Ha, thank you! you've been a major contribution to the car. What is it so far? Sprint RE and custom gauge mount?

My thoughts exactly, I do have some cut to fit wires left over from previous experiments. .

I remember you asking that and my understanding from it was that you would have to make your own mount like I am. I'll be bringing some metal off the bottom mount, front stud. Regarding the width of the mounting ears for the coils, I guess you'd have to trim them. Something like this:

Hi I was referred here and can reply to you now if you like?
Problem with 12A (apart from width) is I have no 12A housings here and I cant verify the exact plug locations.... makes it hard to guess bracket system for it.

Even the IGN-1A system due to variances in coils and other shit means that needs some shimming and slight angling of COP Adaptors (I know that is speeeell wrong LOL but I stick with it) to get it to line up.

There is no such issues with the M&W CDI set up, this is why I decided to stick only with that. I wrote in the other thread that I may continue to supply the COP Adaptors so end users can make up their own bracket systems, had a few 20B people request this.

Hope you all understand, just that IGN-1A type coil is a full on C-U-N-T, it would be so much easier and neater if it was a female end like the M&W CDI coil then I could fuck off the complexity of the COP adaptor unit itself.

I may look into doing an injection mold and forming some type of integral silicone boot with an internal contact? but that is expensive ............. Just doing a BDC or HC type typing brain fart idea over the internet lol I doubt I will spend more time on it personally, just push the proper CDI ignition systems anyway since they are much better than ghetto inductive coils in my experience.

Back to your original programing now

Thanks for getting back to me. I reread the thread and you did reply somewhat.
I understand the issue completely and the market forces. Making
my own, as Zach pointed out, is the way I would have to go for this. Love
the work you did on the 13B mount. I hope Zach gets his in time. I'd like to
see it at DGRR.

Looking good buddy. Hope u get it going for dgrr.
