I wanted to know what is the diffence b/t an 94+ LS turbo and a GSR turbo? What do you have to change to put an Ls turbo on a GSR motor? Thanks

 

If you are referring to the exhaust manifold then they are the same. The VTEC head is larger than the non-vtec so if you had a big turbo then it might not fit with the larger VTEC head. Unlikely, but still a possibility and something to consider.

 

I'm actually talking about the entire kit. When I see turbo kits for sale for 94+ Integras, there is a choice b/t a Ls/Gs kit and a GS-r kit. What is the Difference?

 

Differance is the exhaust manifold, and the intercooler piping.
The LS piping is shorter than the gsr piping.

 

the downpipe is also differ.

 

NO. the exhaust manifold is usually the same. it all depends on the clearance factor... some manifolds are made differently for race applications. most exhaust manifolds for B-series fit, regardless if its a LS or GSR. the obvious difference is the intercooler piping, because the throttle body/intake manifold sits lower on GSRs. also, the turbos might have different specs, designed specifically for LS or GSRs. sometimes, they almost work the same way... so it all depends on how much lag and high end the turbos create.

 

Thanks a lot guys.
