Hello everyone. I do all my shopping for parts either at Up Garage (those in Japan might be familiar with it) and online at http://www.rinkya.com. It's a Japanese site like e-bay but they do have a translation service. Bakc to the topic, I want to know what parts are interchangeable for the R33's RB25DET from the RB26DETT. I want to make more juice while keeping the vehicle as stock as possible (at least on the outside). If any of you have some knowledge on what works, I'd appreciate the help. Thanks!

That could not be more vague. The entire reciprocating assembly drops in. The head bolts on with modifications to various water passages and you would have to drill the head bolts holes in the 25 block oversize to accept the bigger 26 bolts. The 25 parts are fine though, 26 are'nt needed unless you want the bigger displacement or the ITBs.

yeah. You gotta be more specific than that man. I heard you can change the valve covers, but that's a pretty cheap way to be a poser.
