Any suggestions.

[951's 330i]

hey everyone. So i finally want to start changing some performance parts on my car.

S14 RB25det S1
Pretty sure a z32 fuel pump, but need to make sure.

My goals first of all are to reach 375 to 400whp. But trying to keep most of it stock till i can afford to rebuild the whole thing the right way later on. Here are my plans.

Turbo: Holset HX35 non-internal wastegate.

Injectors: Im thinking of getting the nismo side feed 740cc, or the deatschwerks 740cc.
Im leaning more now towards the deatschwerks because of price wise. Plus i havent really seen any bad reviews on them as well.

Now im not sure but i think these plug straight into the stock fuel rail? But my question is should i leave it like that or get a new aftermarket one all together?

Tune: I was thinking of getting a z32 ecu and then nistune. I think for the numbers i want that might be ok but I think maybe i should get the AEM EMS. Money is the only real thing making me want the nistune.-Going with Apexi Power FC. Found a good deal on it.

Wastegate: Was recommended a tial 38mm so i think thats wat ill b getting.

Edit: MAF: Changing it to the z32 one.-Check

I already had this pretty much answered by bardabe, but i just wanted to start a thread about it for others that might also be interested in a setup like this and also for anyone that has experienced this turbo can throw in some help. Thanks to all that attribute.

I got a buddy with an RB25 in an R32 GTS-T putting down over 600whp with this setup. Might help give you an idea or two...

RB25 (stock bottom end)
HKS 264 in/ex cams with matching cam gears
Tomei valve springs
Tomei headgasket (stock 9:1 compression)
ARP Headstuds
RB26 oil pump
RB26 individual throttle bodies and surge tank using port matched adapter to RB25 head
100mm intake piping
80mm intercooler piping (ebay special)
4'' (4 core?) intercooler (ebay special)
Full exhaust with RSR catback
RB26 D-Jetro Power FC with boost control kit
Stec top mount stainless manifold
2 Stec 50mm wastegates heavily ported
Holset HX40 turbo with 19cm ex housing

After riding this car...I like HX40s alot...

all I can say, is Holset's are the shit.

nistune will be great for that

Lol thats y i cant wait to get one. But then i was kinda thinking.

Since im only going for around that hp, shouldnt i just get a 71/76r? But i think price wisae those are more expensive, and then theres the "what if i want more poooowwwwaaaaaaaa!!!!!" lol

Also i would think that the lag time would be significantly diff. from the holset turbo, but then again i dont know the fool spool time. I heard hx35 spools fully at 38? or starts to spool there. I dont think thats really THAT much of a lag but if the 71/76r fully spool at like say 32 then that might be a better option.
