You'll have to go custom. Other owners have had them made before, both higher (NA) and lower (FI).

I can't fathom why the heck you'd get rid of the SR20 in that car for the heavier, weaker internal qr25.............

but yea, any internals you get are going to be custom. almost anything is custom on this engine. And repairs/parts are not cheap!

hey thanks for the reply...the reason for the swap is cause ithe guy who had the car before cracked the block..from oil starvation so really i have the shell..i had the qr 25 de from another car that i no longer have...so i though it would be a good idea to try the swap...no one around here(ottawa) has done it yet.

only one other person that I'm aware of, anywhere, has swapped a QR into an NX...because it's just that, not a good idea.

good luck to you though man.

i know it's not easy but that's half the fun-- the piston are for the turbo kit i want to install. i have the engin all apart so i got the seal and bearings but all i need was the pistons and rods, i talked to people at je they said they could make them . it's getting them up here cross the border that might take a little while.i'm not sure how long i want to wait,to get this on the road. i found a guy in qubec city that did it and he said it took him 5 days for the install, but that wasen't at a shop,i have a shop that i can put it,so i don't think it will be to hard(i hope)

Travis of Forced Induction Racing can do this. While his customer service has been debated at times, his knowledge of the QR25 is impressive (And Nissans and general). He's a damned smart guy and has done some major building on the QR in turbo applications and N/A applications. IIRC he has even destroked a few QRs in his day.

Travis never destroked a QR (well, one that ran for more than a couple of hours without somethin blowing or breaking.)

Avoid Travis. I'm sorry, but he's too risky, and you can even ask one of his most recent customers and he also used to be Trav's most staunch defender.

Jamie at powertech imports can get you what you want....almost anything you want. email him. sales@powertechimports.com

Jamie is an excellent individual to do business with. A guy bought a turbo kit from them and is receiveing it in March, and he happens to have an AEBS header in flawless condition. As basic knowledge goes, you dont need a header once you turbocharge, so the dude is selling me his AEBS so I owe Jamie some props indirectly.

Well not free but a damn good deal. I pay him a small amount of money, he pays shipping on the AEBS and I ship and send him my stock exhaust manifold and midpipe in case he wants to go back to stock. Overall, for a perfect condition AEBS that has every single part that it originally came from, its a good deal. And after talking to people who have done business with Jamie, if Jamie said the kit will arrive in March, it will arrive in March; and not March of the next year.
