I've had semi stock sr for 2 summers now and i want more hp lol so i've made a list of parts for my goal of around 300 and something hp. feel free to comment on it.

APEXI= head gasket 86x1.1mmARP= head studsBC= spring, retainer, not too sure what size of valves yetBC= 264 intake and exhaust camsGREDDY= top feed fuel railtop feed injectors 660cc?NISMO= adjustable FPRCIRCUIT SPORT= stainless steel turbo linesNISSAN= z32 MAFGARETT=gt2871r with .64 A/R and ill probably go with an ENTHALPY tune

I already have bigger rad and fmic, walbro and guagesthis set up is roughly going to cost 4 grand + extra for canadian dollar and who knows what else i'll need

why are you wanting top feed injectors?by not doing that you can save a little bit as well.

If you don't have it done already I would can the top feed injector idea and go with a greddy oil pan for reliability purposes. I'd just reuse the stock valves but I would get new stem seals and have a machine shop check them over for you and reseat them; there really aren't any spectacular valve upgrades unless you wanna empty your pockets you can go with ferra valves but they're ungodly expensive and un-necessary for a 300hp setup. The BC valves aren't any better than stock. You can get a nice set of side feeds that'll work with the stock fuel rail fine. I would go with some 740cc's and an adjustable FPR. Thats just my 2 cents... I just finished my build and havn't put the motor back yet but I got:

-BC springs/titanium retainers with 264/264 cams-ARP headstuds-Tomei Headgasket-Tomei expreme exhaust mani-Greddy Intake Mani-Nismo Adjustable FPR-Tomei 740cc injectors (tomei and nismo injecors are made by the same company so it doesn't matter either way)-Greddy Oil pan (very important prevents oil starvation which is usually what kills these motors DO NOT BUY A KNOCKOFF)-Greddy RAS-Garrett GT2871R .64a/r with stainless steel lines internal wastegate-RS Enthalpy tuned

I was told by the good people at enjuku racing that I can push 400whp with this setup but I'm only shooting for 350ish at around 18psi... If your only looking for 300ish you could go with smaller injectors (550's) and ditch the greddy intake mani b/c its very expensive and you loose torque, you could probably even go with a GT28RS turbo itll spool a bit faster. You could also go with a different turbo mani... the megan racing one is actually a decent design and its cheap but probably can't handle much over 300hp without cracking. I'd def get that oil pan and replace my oil pickup tube tho; you don't wanna blow up all that hard work and money.

Wouldn't cometic hg be cheaper and do the same plus just swain coat and extrude hone for the mani. should cost the same as a tomei and wont crack ever or this might be wrong but wouldn't the ichiba ver2 work the same as tomei without the price tag. just suggesting to save some money please correct if i'm wrong btw is the fpr necessary or suggested?

Cometics take too much work to get a proper seal. Cosworth have proven to be great headgaskets at they're not too expensive.

Tomei's, Ichiba' and megan manifolds all crack eventually. The extrude hone porting and swain coating method will probably run a little more than a tomei manifold, but is definitely worth the extra expense. I suppose you could save a little by opting for ceramic coating...maybe?

thanks for your input guys!

so you guys think i can cut out the top feed fuel rail and bc sprin/retainer/valve

of course though i will be checkin the valves and valve guidees and springs for wear(mircrometer time yay!)

what manifold should i get i heard stock one should match up but i know it isnt the best...

If your getting more than 11mm of lift I would get springs. I have tomie 260's with 12mm of lift and BC springs with stock retainers. P2M has BC sprigs for less than $100. I would also go with JWT for the tune. I love my setup and personally I think it is much more accurate 1st time rom tune than enthalpy. I know several posters who have had problems with BC cams and stock springs, especially if you're revving over 7000rpm. My JWT tune rev limits at 7750.
