So, I'm buying this 180sx (4000$)

I'm currently shopping for parts, I want a strong and reliable build that will survive all the abuse it's gonna go through. My power goal is 350hp but for now I just want it to last.

Here are the parts so far.

The cams are 270/270 12mm and the head gasket is 1.2mm. The valves come with their retainers and all included.

Do you guys see any incompatibilities? And what kind of hp are we looking at? (I'm looking forward to get a gt2871r in the futur.)

Sorry for the double post but did I post in the wrong section? 50 views not a single reply. :|

This question has just been asked 1 million times is all. That parts list seems fine and dandy but if you don't get a tune none of it matters. Get the gt2871r + a fmic + a tune and you'll have no problem making 350hp.

I'm gonna get a tune it's a must for me. (And it should be a must for everyone.) My concern was more about the parts list compatibility, but I thought I could ask a few more questions too.

I know I'm gonna have to make some modifications on the cover for the rocker arms stopper and RHDJapan mentioned something about sheet cut for their oversized valves, not sure what kinda cut it require.

Anyway, thank you for your time, sorry if these questions were asked before, this is a big forum and I'm new to it.

Best regards, Mayer.
