I read the n/a to tII thread it was people just arguing. I want to get facts. I have a 87 n/a I want to throw a 95 gsx turbo on it. Does the ECU need to be changed? I hear the n/a tranny only handles 250 hp. I saw specs that only rated tII at 184 hp. So i should still be money. Do i need to purchase new sensors? I have a posi rear end that can handle it. I heard someone say that the driveshaft has snapped for some people? this true? Thats all i can see for concerns. If anyone know from EXPERIENCE than post other concerns.

I think that turbo will be too small and cause issues.

Yes about 200lbs of torque is the limit of the N/A Trans.

Driveshafts do not snap the u joints go bad and make break and fall apart.

why would a small turbo be a problem? it really depends on how much boost you want to run right? correct me if im wrong but if hes just gonna throw the turbo on his 87 n/a then a smaller turbo with less boost is better, hes less likely to blow his seals.

Turbo is too small.&nbsp I believe the stock turbo off a 2G DSM turbo is a Garrett T25 based turbo.

If the turbo is too small, it'll give you one helluva kick at low RPM, but it chokes at higher RPM.&nbsp The resulting backpressure is BAD for the engine, because it builds up unnecessary heat and overspins the turbo.

How about the turbo off a 2g DSM then...With only runnin like 5 lbs of PSI, could this be accomplished alot easier then what aaron cake did to his car?

his car seemed to take forever to do...

Correct me if i'm wrong but you will need a custom manifold, Turbo, intercooler, boost sensor, gauge...and i can't think of anything else...oh BOV and perhaps bigger injectors?! controlled by an S-afc

With a stock DSM turbo you will be wasting your time, it is to small for a 2.0L piston engine, and miniscule for a rotary. Turbo's that are too small will not hold boost to redline, and one with an exhaust wheel/housing as small as a T25 will end up giving you EGT's out of this world. There is a little more to turbocharging an NA then going to the junkyard, grabbing a turbo and throwing it on.




Really with the price of most S4 TII's under $5000 it just not really worth turbo charging an NA, you can just buy a TII cheaper.

thats wasy for you to say. I live in iowa. You try to find a tII for sale in Iowa. Cause ive been looking for 2 months and havent found one. As far as the turbo goes. I know a guy that pretty much blew is motor and is getting all new. It was offered to me for cheap.

It might be neat to get two, and run them in parallel, one per rotor, but that's still pretty avant garde. If you really HAVE to have a TII, buy the hood, longblock, IC, drivetrain, pressure sensor and ECU, and you can reuse the N/A ECU by splicing/rerouting a few leads. It's not particularly pretty, but it will get the job done.

There's more info out on the web - seek it out.
