Are there any threads that deal with this? I have a 1998 Firebird V6 with a 5 speed manual, and i would like to convert it to a LS1 or LS2 with the T-56 6 speed manual.
Does anyone have any kind of advice as to how to do this? is the difference with a conversion from the 3800 much different to a LS1 or LS2? Or are both motors about the same. As i have a friend that might give me his Truck LS2 engine. I believe its called a L98?
Also, how do u convert the instrument cluster? is there a thread on that as well? or is it just a straight swap between the v6 n v8 clusters?

Thanks for your help and advice

get the computer and harness with it that is the most important thing. as far as instrument cluster just get find all the parts you need off a donor car.

However if this build is going to end up costing you around 5k your better off just buying a LS vehicle

If your dead set on doing a conversion, i'd go with the LS2. that being said, it's a lot of work. You'd really probably be better off buying a new car or find a wrecked "donor" car. Off hand, you'd have to switch the Engine, PCM, K-member, and transmission. Other things you might need to change would be: rear end, shocks and struts, and maybe the driveshaft. Good luck whatever you choose.
