Ive read about all the turbo 2 swaps and i know they are by far way better than making the gsl-se motor turbo but what about just putting low compression rotors and keeping everything else the same ? Yes i know the turbo 2 manifolds are better flowing and its alot better suited for a turbo of course but i'd like to make the engine bay look almost completely stock. I thought a mild street port , low comp. rotors and a microtech and yes i know how much work goes into all of this but its damn worth it. A first gen with even 275 hp to the wheels would be hella fun !

 

Holy Mind read Batman!!!!!! I was sitting in bed last night and I had the same question!! Wow I guess great minds think alike Yes I would like to know about this too, I just bought a 84 GSL-SE with a blown motor and plan on another rebuild.

 

If it ramains a 6 port, you'll still need to run a spacer for the exhaust manifold.

 

Yes, you can use low comp rotors in the older engines.

 

Why do you need to run a spacer?

 

Because if you use a stock turbo you will hit the intake manifold. You can run the stock gslse rotors they are 9.4 compression the S4 turbo rotors are 8.5 compression. If you plan on running a microtech 9.4 rotors will be fine just make sure you get it well tuned. Personally I'd get a complete 13bt, engine and transmission, and swap it in. But if you want to build up the 13b out of the gslse I'd go the route of putting 4port 12A plates over the 6ports. I just can't stand the 6port design just my preference.
