I've come to a cross road and seeing as I'm the only one in my crew with a rotary i turn to this forum for help again as you all have always helped me in the past. I've got the bank and some nice deals on a s5 swap and an s4 swap. I need to know if any of you had a choice what swap would you go with and why. this is going in an s4 88 gxl. Right now I'm in the middle between the s4(what i believe to be an easy swap) and the s5(what i believe to yield more power but i also believe to be the more difficult of the two swaps) if anyone can convince me that swapping the s5 isn't that hard i can go with that or if its to hard i can do the s4. Both swaps include ecu wire harness transmission, and the s4 includes a drive shaft to make the turbo tranny bolt up to my stock LSD.

 

Go with the S4, use your n/a wiring harness.

 

Man...Im in need of help I have a 88 and use the S5 turbo swap. My car turns over but will not start for nothing. U have any ideas?

 

You should start a thread for your question, since you'll either jack this one or, more likely, not get responses because it's a separate question and off-topic. In that thread, you should post details of what your setup, what your car does and doesn't do, and what troubleshooting you've tried (eg, confirmed fuel and spark, for starters).

 

id say go with the s4 but put a s5 turbo on it(better wastegate)
