I work for a company the sell Toyota Landcruiser parts, and when TRD came out with their supercharger, they did no extra timing of fuel change. We took it to a place in Culver City that had a 4 wheel dino and with a new fuel pressure regulator, and a constant flow fuel pump, they added a UNI-chip which is a pigiback computer and we picked up 70hp to the wheel.

 

I'll bump the thread for a second:
I found my turbo and brought it to the dealership. Going to be talking to one of the service guys soon about having it installed. My spec sheet says "TA34/T04E 57 trim/76 trim .63 A/R". It's a pretty big turbo. The real challenge will be finding a place to mount it. If this is feasible (and if anyone is interested), I should have my cost information and, hopefully, an installation guide by next week. Still shooting for at least 300hp eventually, but I'll settle for whatever I can before modifying the internals (reflashing aside). Not like I have really have a choice.

 

Rear mount turbo, is the only way to go. In my opinion, because of the firewall being so close to the engine already. Also if HPtuners ever finish there tuning software for the 2.4 and 2.2 it will be great. With their software you can program every aspect of your ecm. :) They have great support for the J-Body community, and the cobalt’s. I know they have been working on it, but I have not heard a response back from the founder yet. Here is their web site.
I guess we will have to wait and see.
Also I would highly recommend increasing the line pressure of the transmission if you want it to live longer than a year, might also need a transmission cooler, because of the added heat of the increased line pressure and added force on the transmission.
Also
Maybe at 12 pounds of boost. I know that at 2 lb of boost on 2.2 ecotec they normal will barly see 200 if they are lucky and VERY well tuned. As I come to see the 2.4 responses better and easier to a tune in a NA form, instead of force induction.

 

Rear mount is a good option if you dont mind not being able to run on a race track. I heard form our local track guru that NHRA is goona not allow Rear Mount Turbo for 07.

 

WHAT!
That makes no sence to me. I bet that will piss of a few people at the track that I race with!

 

Well i was told there are track saftey issues with the turbo mounted back there, namley the long oil feed and return lines theat tend to fail. He did say that STS makes a good kit , but there are a lot of people maiking their own rear mounts and theat is where the problem lies, i guess. I was gonna STS my 93 camaro, but i think a 150 shot of spray my do the trick instead.
