Some build advice please

[woowoo16]

Okay recently purchased an s13, with an sr20det and I'm tying to get a solid 360-400 whp
Currently 310whp on shell vpower 91. 14 psi
mods:
-Garrett gt2876
- full 3 inch straight exhaust
- power dc d jeteo ( datalogit also not installed)
- Godspeed intercooler and pipes
-mishimoto radiator
-new act stage 2 clutch
- dueshworks 780cc injectors
-walbro 355lph pump
- 2 way LSD
- aem wideband and boost gauge/controller

Compression even across the board

I've been reading for a while and come up with a list just not sure what I'll need and what I won't

- steel head gasket and arp studs
- rocker arm stoppers
- cams, and springs ( opinions)
- maybe a fpr?
- new hot pipe. God speed one is really
Small.

I would like to keep the stock Engine till it pops. This isn't my Daily driver and
And I plan on gathering parts for an rb25 swap over the winter

Specify what motor

rocker arm stoppers.... SR20DET?

[woowoo16]

Ohh yeah sorry guys, sr20det red top

water/meth kit from aem or similar.
the list you already have is pretty solid.
once you're in the upper 300's you're closing in on that fine line where you'll wanna consider building the bottom end.

my question is, if you're already planning on doing an rb swap, why invest more money into the sr?

[woowoo16]

I don't want to rush an rb swap so it might get kind of expensive if I do
It the way I want. So I'm going to try an spend the little
Bit more to extract the most power I can from this little 2liter

Any recommendations on cams? Or rpm limit I should be looking to hit?

[brndck]

IMO, best cams on the market are jim wolf. Yes they are expensive.
If you can find some tomei poncams or Greddy easy cams that is a solid route as well.
Unless you are building the head with valve train work (aftermarket valves and stiffer/double springs) I wouldn't recommend going over 7200 rpm.
