Feel free to comment on the setups! I want opinions( preferably from experience)

My current setup is s13 w/ blacktop sr20det stock turbo
i was told it has hks cam when i bought it but not %100 sure.
otherwise i think it is stock engine.
fmic
greddy bov
header
megan3" downpipe
manual boost controller
stock ecu (I think)

Mods im planning on doing:
walbro fuel pump
Catch can
z32 MAF
Arp head studs
Head gasket( cosworth, greddy) Cometic???
rocker arm stoppers if i dont already have them?
Valve springs? brian crower? Hks? or Greddy? not sure if i have too, would rather be safe.


Then other mods:
555cc deatschwerks will they be big enough??
Ecu tune (enthalpy/secret service)???
I am looking at this turbo kit FRSport T28 Dual Ball Bearing Upgrade Turbo Kit for S13 SR20DET
http://www.frsport.com/FRSport-T28-Dual ... _7971.html

with either the (s15 OEM turbo spec r) or spend a little extra and get the (GT2871 .64)
and also get the z32 used MAF with it, that should Be a fairly straight forward turbo swap either way right? not to much modding.

I DONT KNOW what horsepower im shooting for, I truthfully could leave the car the way it is but of course more power is more fun, i just want it to be more fun and still reliable!

that all basically sounds like the Spec R Silvia S15
550cc inj
disco potato
walbro
manifold + fmic

them cams will give you a lot of HP
but basically you have a spec R upgrade list

^ This. Those mods should get you easily 300-350+hp. Depends on the tune.
Don't get a cometic gasket. I know they have been hit and miss with people, but notice like on ebay why they are "free" when you purchase pistons/rods combo sets or single. Get another brand head gasket.
