Alright guys. I have an opportunity to get an S4 t2 but i'm not sure if i should since i want to drop it into my 89 GTU. Do you think this would be a great idea since i would be receiving the whole S4? I could do a complete swap on engine, tranny, and undercarriage. I would love to do this but I don't know if it's a wise choice since the S5 engine is a better engine. What you think i should do??

 

Whats wrong with the T2? I would think that it would be easier to fix the T2 than to do a S5-S4 swap.



Thats actually how my car is. It is a wiring nightmare unless you convert the S4 engine to a S5.

 

You think the S5 N/A is better than the S4 TII

 

Well the T2 was in an accident and the frame is bent. the engine is good along with everything else. The engine on the T2 will need a rebuild cause it has over 120000 miles. My GTU is a good vehicle but is lacking the power i want. It has around 90000 miles on it and is due for a rebuild sometime soon also.

 

Thats what I thought.



Since you have a S5 engine already, it will not be hard to convert the T2 engine to a S5, then get a S5 T2 ECU.

 

sounds great! I was also looking at a jspec engine. but i cannot find one for a good price. do you think i should stay with the usdm engine or would a jspec be a better swap? I plan on going turbo without the turbo hood and get a front mounted intercooler and have it painted flat black to camaflauge it somewhat. i want the gtu to look like a N/A but have the power to run with the big dogs.

120,000 miles on a rotory is not alot... there so balanced and only have just a few moving parts... that engine should last you a while unless its been abused and not taken care of... mine has 175,000 and runs like a champ... ive actually been trying to blow it up for a few months now so could have an excuse to do a rebuild/port. put that T2 in the car... it will be worth it...

 

There is no point in getting a JDM engine if you have a USDM one, there is no power gain by using the JDM, it just a few very minor differences to the intake manifolds/sensors, but not enough to make any difference.



I would suggest rebuilding that engine even if it has 120K on it..you might as well get it done now before putting it in the car, doing a bunch of work and then having to pull it back out later...just an idea..

 

1000-1200 is expensive for a J-spec TII block? That is dirt cheap. Go to www.rotaryshack.com.
