Over the past few months I pieced together a rearmount single turbo kit on my C5. The car worked great last year on the nitrous, but I grew tired of filling the bottle, so after some research I decided to take the FI plunge. I removed the G5x3 cam and installed an 02+ LS6 cam w/ Comp 918's. I kept the RPM Trans, Fuddle 3600 Stall convertor, Line Lock, and MT ET streets from last year.
The rest of the turbo kit consists of:
Exhaust/Turbo:
Z06 manifolds
2.5" (x2) to 3" 304ss merge collector
3" 304ss exhaust pipe
Heat Wrap, Exhaust hangers, gaskets, flanges, etc..
PT76GTS
Tial 44 WG .6 bar spring
Oil feed/Return:
-4 SS feed line
Check Valve
-10 SS line (turbo to pump)
REV GP-301 Oil return pump
Various Lines and fittings
Intercooler/Charge pipe:
3" Aluminum Charge pipe (Various bends and straight sections)
Tial 50mm BOV
Top/Bottom Intercooler (27x12x4)
Silicon and T-bolt Clamps
Intake: 4x9"" Filter on turbo
Fuel System/Controls:
Twin intake Walbro pumps
-8 feed line
Billet Rails
Aeromotive 1:1 FPR
Various Fittings
Motron 60# injectors
2 Bar Map sensor
HP Tuners 2 bar SD BlueCat tune 9.5psi Pump Gas
It went 10.85@126 and 6.99@100 on a soft 1.69 60'
It also went 10.86@125.8 later that day. I'll try to scan slips and post up some more videos next week.
I ordered a tighter convertor upgrade from Fuddle, should be here today, hopefully that will help get the 60's back into the low 1.5 like last year. I'm very happy with the car, how it drives, how it moves down the track, and the fact that I still drive it EVERY day with very few issues. Thanks to Dan, RTC, and all my friends who helped me get it together.
Anyway, just thought I'd share. Enjoy.

looks awesome! i know you said it even thought it isnt in the pics but exhaust wrap those pipes seems to make a huge difference, not to mention it will help where that charge pipe and exhaust pipe seem to run kind of close. but other than that i love the setup very well thought out and implemented imo

Yeah, it is tightly overlap wrapped from the collectors back to the turbo. The only spot where they're too close is on the passenger side, near the starter. I had to get creative in shaping the pipe to keep them apart.
I also added a 1/8" skid plate on the bottom of that flattened pipe going under the front aluminum sub-frame. It scrapes occasionally.

Wecome to the 10 sec rearmount club, wish my car was as light as your vette. Start upping the boost slowly now
Thanks. I read alot of your posts as I was planning this project, very helpful information. Congrats on getting into the 130's btw.

looks good, what kinda times did you run on nitrous?
Best: 10.98@124, 7.0@100, 1.53 60', usually 11.0-11.1 @ 123-124
That was cam, 150 shot, bolt ons, Trans and Convertor.

looks good. do you have anymore info on your twin walbro setup?
I removed the factory plasting pump housing, installed a -6 bulkhead fitting into the pump housing cover plate, and installed the pumps to the conver plate. I used some large filter socks on the end of the pumps that are angled so they lay flat against the bottom of the tank.

I use MT ET Streets, non-radial DOT in 26x11.5x17 on some factory 17" wheels. my car 60'd in the low 1.5's last year, on the bottle. However, it's not 60'ing as well with the turbo setup and convertor issues. I think the best 60 i pulled was a 1.68. Hopefully the new convertor will help the car get out of the hole better.

The Datalogger showed the engine flashing to almost 6k at WOT. I think that's too much slippage. It would flash to about 4K on the cam/bottle setup and rocket off the line. Hopefully the tighet convertor will let the car come out harder, and mph better n the top end, and be more efficient for daily driving.
BTW the new TC did arrive yesterday. I'll be installing it sometime next week.
