hey man sorry someone pulled a fast one on you with your "VE". On a good note, I really like the RR motor, its really a under estimated motor that shines in reality. Vadim did a test stock for stock on VE vs. RR and the cars compared had near identical speeds and response (iirc trap speed too) Fix that turbo and you wont really care if its vvl or not
Also im not really sure what harness your running now or ecu. but if its a stock RR harness right now...
its really simple to get that IACV issue straightened out im sure you researched already. As far as wiring goes for that RR harness Vadim also made a thread that shows you exactly how to do it. I know your strapped for cash but all these steps wont burn holes in your pocket im sure!
There are a TON of LP p10's in the junk yard 30 mins my from home, if you want i can arrange for me too pull you a IM and a harness. ( you will need a 99 g20 or b14 harness (16bit ecu) for that IM and splice that into your RR harness) Hit me up if your interested and dont give up on this car!
but
if its a b13 ecu and harness on the RR engine then all you need is that IM and your good to go. just grab a fresh IM->Engine gasket from Nissan
