yea,you cant get it in the US, I just bought it bout a week ago so IDK what ECU im using im guessing the ssame one on the Qr25. The dude that had it before me rode around with the idle running aalmost 2000,i had to do the idle relearn thing lol
I will have to disagree there my friend, my friend just had a QR20 swap since the mech lied to him and bought one cheap of EBay instead of getting another QR25, the lower end tq is missing and it lags quite much on top...there IS a power difference, of about 20hp...plus not Hyundia Tiburon 2.0's will be able to race you...i know since He used to smoke a friend's tibby, and now its not the case.
have you looked at the block to verify its a qr20 or did you just take his word for it? a half liter displacement loss should make a noticeable difference.
Why would no one believe this without pics? The only difference you will see visually is the intake manifold...and thats if he didnt just use the spec v's im.
I don't know the actual numbers, but I have a chance to ship QR25de 6spd tranny back to Asia for a customer's requirement because he has a qr20. I had a chance to ride on his car, stock qr25 v.s qr20 6 spd. I really didn't feel that much difference...
not too hard to believe IMO. There is a guy on nissanclub who swapped a qr20 into his L31 atima and ran the qr25 ecu. He reported that it felt almost the same everywhere except on the highway. Passing was a bit harder.
Please don't. If you're gonna do it, get it done right with quality parts or send it to travis. We have had our share of fail vq swaps that got sold off to good people
I like that you have a QR20 btw....they sell them on Ebay. My friend has one in his 02 Spec V. After driving it, then going to mine (I know I know I'm turbo'd...BUT I drive plenty of other QR25's), the top end is not there so much. You can just turbo that QR20! If I'm not mistaken alot of QR25 guys try to place QR20 pistons in for better compression...SO you have that at least.
