My 91 Camaro LS1/T56 Swap
Hey guys ive recently decided to make the big switch.
Im headin to get engine and trans this upcoming weekend, and tonight i pulled out the fuel tank to put in the much needed Walbro 255.
Planning on just doing headers, a nice intake and calling it good for now.
There's already 4.10's in it, so itll be plenty peppy

Wow, another member that doesn't go for the red painted aftermarket stuff. We're a rare breed, you know...
Either don't get sticky tires, or don't do clutch drops with that 10-bolt. It won't stay peppy very long if you do both (ask me how I know).

Re: My 91 Camaro LS1/T56 Swap
Why are you selling the pedals if you're going with a T56? You can re-use them, just do a search in here for my little remedy for making the 3rd gen pedals work with a 4th gen master cylinder. It cost me a whole $5.

Re: My 91 Camaro LS1/T56 Swap
The 3rd gen pedals are better than 4th gen ones, FYI. They're a lot more sturdy and will give the firewall more support when bolted down.

Re: My 91 Camaro LS1/T56 Swap

Re: My 91 Camaro LS1/T56 Swap
it runs! doesnt idle right, so gotta get a scanner hooked up. idles rich and when you stab it, it wants to stall.
still gotta install the wonderful pedal assembly and bleed the clutch out.
then its time to drive

Re: My 91 Camaro LS1/T56 Swap
i appreciate the info....with all the reading i have been doing, i think i'm leaning towards doing a 6.0L LQ4 or LQ9 with a cam, LS6 intake and adding the LS1 accessories. Looks like I may be able to start buying parts...just need to find more room to hide stuff from the wife! haha

Re: My 91 Camaro LS1/T56 Swap
Well, I'm hoping to join the LS1 crowd too. I've had a good time with the old SBC stuff over the years, but its time to go LSX power and I can't friggin wait!!
I'm working on buying a wrecked 99 LS1/T56 car now, I'll know next week if I'm the lucky (or deepest pocketed?) owner.
I'm just plannong on headers, fuel pump, and clutch for now until I get all the bugs worked out and learn more about the LS engines. With my 4.11 gears already in the 9", I'm expecting a nice running, durable car.
