Hello, I am probably buying a 88 GTU in the next few weeks..And the guy im buying from doesnt know what HP he has so Im posting to get an estimate on power..The mod list is: HKS Filter, Ported Intake manifold & throttle body,Racing beat ceramic headers,Dual 3" exhaust,Crank pulley, Light weight flywheel,Turbo 2 transmition, Turbo 2 drivetrain,Rebuilt GTU 13b N/A engine w/ 3mm seals, MSD ecu & other mods to the body and suspension..but those are the engine mods i know of..How much HP should i be running..and what other mods should i do?? thanks

 

I would say 160-175 at the wheels at the most. why the heck did he get a TII drive train?

 

Not sure why, He did alot of building on the rear end and suspension and I guess he needed to replace his drivetrain and tranny so he got that. He takes excellent care of the car.

 

What other mods should I get for the car? Would i be best to swap in the turbo engine?

 

dual 3" exhaust on a N/a is too much. Try 2.5

 

its 3" to the split and then its 2.5 to the ends.

 

Oh that might be right on for a collected.

 

It would seem like a waste if you swapped in a 13bt since you have a rebuilt motor. How many miles on the rebuild by the way?

If you do decide to swap the 13bt engine in you will need to get a new exhaust since the headers will not bolt up to the turbo exhaust manifold. If you go with large diamter exhaust with no cats you will have to do fuel mods (upgraded fuel pump probably a walbro and FCD.

 

140rwhp or so I'd say. They dyno at like 115rwhp I believe.

 

it has 40k on it..140HP??? Is that more accurate than the other estimate? Do you all think id be better off buying a turbo fc? or maybe even an FD? The car really is in excellent shape..Im just kind of weary of buying a N/A...

 

TII you will have 182 at the crank with no mods and have power ready to be opened up for cheap. The NA is cool because it is slightly lighter and its all motor. I personally love the whine of a turbocharger but NA has a lure to it for me as well. Go with whatever you want. You will be able to make much more power, much easier with a TII though. Although, the NA will most likely last you much longer.
