Haha yeah, I figured I'd switch my name to what it really should be. My other screen name (Chudson coupe for those that don't know) was created for my G35 coupe when I lived in the Hudson valley region. And since I was on those forums with that name, I kept it simple and just kept it when i joined the other rx7 forum.

The only reason i haven't been on here that much is because I'm usually just browsing 3rd gen classifieds, and that section on here doesn't have too much volume yet.

RX SE7EN is actually the license plate that I was going to get...until NY changed to the stupid yellow plates just when I was going to order it

I don't want to switch over to that awful/ugly yellow plate, so i'm sticking with the old style plates.

Bubbles, any chance you'd like to media blast some parts for me? I'd like to clean them up before sending them out for coating. I could trade you some parts for the labor?

RX SE7EN · 03-20-2011, 07:19 PM

Check it out, bolted down and lined up (the bolts are temporary, I'll be ordering some better fitting, nicer looking bolts and spacers this week):
(Stock Belt works, but still working on mounting a tensioner)

This is the stock outlet pipe from the mercedes. I bought this so that I could have the smoothest transition coming out of the charger as possible. I'll be hacking it up and putting on a 2.75" pipe pretty close to the supercharger, so the big hole that you see won't be there for long. Notice it fits under the strut bar

Relocated fuse box to make room for intake piping into the throttle body from the intercooler:

The big box is mounted on its original bracket which I cut and bent to fit in the new spot, and bolted to a factory threaded hole. I still need to make a bracket for the smaller box.

Now its onto the piping.

I also removed the T78 turbo today (it started smoking at the end of last summer). I got the cold side housing off, the blades look great. I didn't get the hotside off yet, i'm a little worried about the blades though, before I got the car the engine had blown. and when I was getting it tuned last time they said it wasn't making the power that it should.

I got the band off that holds the hot side housing on, there was oil underneath it, so I at least I found the source of the smoldering smoke coming out from under the hood after it got hot.

There is a little slop in the shaft, I've seen worse, so hopefully the rebuild doesn't cost too much.

Does anyone know a good turbo rebuild shop? Must be someone that can do the T78.

RX SE7EN · 03-24-2011, 01:51 PM

What are you guys using for circuit breakers when relocating your battery to inside the car? My battery is in the rear bin and doesn't have a breaker.

***TitaniumTT*** · 03-24-2011, 02:22 PM

Waytekwire.com or Delcity.net have marine grade buss breakers for 1/2 the $$$ that WestMarine will charge. I run a 150A

How's the piping coming along man?

RX SE7EN · 03-31-2011, 08:27 PM

So I've hit a slight roadbump. I sent my Greddy T78 turbo out for a rebuild as it started smoking last fall. Prior to that, it had never made great power and was laggy (my car came with the kit and a blown engine), I had put a new motor in and never rebuilt the turbo or even took it apart. I sent it off for a rebuild and this is what is wrong with it:

Bad seals, I knew that, because oil was leaking.
Useless turbine wheel, I was hoping this wouldnt be the case.

The cost for a rebuild quickly escallated, couldn't even find a turbine wheel/shaft in the country. There was one in Japan the rebuild shop could get for $415 (the turbo is no longer in production), they showed me the quote straight from the supplier and were going to give it to me at cost. So that put the rebuild cost to around $900. Way too much. The shop was Midwest Turbo Connection. Even though I can't vouche for their work, their customer service was excellent, and got back to me extremely quick with multiple updates while they were trying to track down the wheel, and also sent tons of pics for me. Customer service like that is hard to find.

So I've been shopping around, and the only thing I could find that's roughly the same size and decently price is a BW S366. So I'm going to try to pick one up next week. I couldn't even find anything used for decent price

RX SE7EN · 04-06-2011, 10:13 AM

It's official, I'm now a Borg Warner S366 owner.
Here is the link: http://www.diesel-plus.com/dd_turbo.cfm?npid=9784

Basically, it's a little larger than my old T78, and will perform better. This is actually on back order and will be hard to get until May, but Mike at Southeast Power Systems (Diesel-Plus online) was able to get me hooked up and its on its way. Great customer service, and great prices. Every place else I tried just said it was on back order from BW and they wouldn't be able to get it until May. But Southeast Power Systems figured out how to get one to me quickly.

It's a 66.1mm compressor, with a T4 twin scroll housing, .91 A/R. I would have liked a little bit bigger A/R, but its not really available yet from BW. I've heard the 1.0 and 1.10 will be coming out in a few months. If I need to, I'll upgrade later on.

The T4 inlet configuration looks slightly different than my T78, so I'm not sure if I'll have to modify the exhaust manifold at all. I'm hoping the new housing doesn't touch the LIM.

My5ABaby · 04-06-2011, 10:27 AM

Gotta love buying a turbo for a 6.0L engine to go on a 2.0L engine becuase the 2.0L engine rocks the 6.0L engine's world.

RX SE7EN · 04-06-2011, 10:46 AM

Haha, yes it is a large turbo. It's not too much bigger than the T78 though, pretty comparable to the T88. I was actually pretty happy with my T78 the way it was, and as you can see, the turbine wheel was in bad shape. So even if the supercharger doesn't work, this should still be an improvement in response.

tweiss3 · 04-06-2011, 11:06 AM

very very nice. I can't wait to see it all together

2.0L???? Whatchutalkingbout???? This is a 2 rotor!

Speaking of... when we doing some more welding Colin? Did you manage to get everything fit as far as piping goes? SC officially mounted? I noticed my little gift for you is still sitting in the box in my box

I'm officially back in the garage tonight working. I won't be able to take tomorrow off, hoping for Friday but doubtful. Next week is going to SUCK, I know that. Brakes are in AZ being finished, turbo's are in AL being finished, driveshaft is in stamford and needs to be picked up, remeasured, probably built again, powdercoating in Stratford, seat in Norwalk, head up my ass, and time is ticking away....

RX SE7EN · 04-06-2011, 07:00 PM

I've barely gotten anything done

, I do have the supercharger mounted, and my oil lines came in. So thats a plus. I cut the inlet and outlet pipes, but haven't cut the new piping that needs to be welded to them.

I did get the bumper off though, (my garage got rammed by the neighbors car and a tool box flew into my bumper

, also cracked my r-magic fender)

So that needs to get fixed too. A whole lotta suck going on haha. I'll have to turn it up this weekend.

RX SE7EN · 04-14-2011, 09:29 PM

Huge updates coming, pulled an all nighter saturday, and got almost all of the piping done. The only piping left is the easy stuff (almost only straight pieces to go, and no more welding piping to cast aluminum)

Turbo also came in, it fits on the manifold just fine. Even more clearance than before. I just need to cut the 4bolt flange off the downpipe and weld on the V-band flange.

I'll also be coating the turbine housing with DEI high temp coating.

My belts came in today, we have tension

and I installed my Tweakit racing idler pulley for the water pump belt (I purchased it last year haha).

Pictures will come tonight.
