Mate Wants 400Rwhp From His R34Gtt

[Unkn0wn]

Hey,

My mate finally got the modification bug and told me he wants to get 400Rwhp from his R34 Gtt.

Its pretty standard atm, with just a cat back fitted.

we have a 3' dump/front, turbo smart dual port BOV, Intercooler kit and pod filter to fit up.

I have been speaking with HP-in-a-box and they do a GTX3076 with Nissan rear housing, internal gate, spacer, braided lines for around 2.5k.

Obviously we will be getting the other supporting mods (z32 afm/740cc/nismo fpr/ally rad/bosh Fpump/clutch) but im just looking for assistance selecting the cams, head gasket and head studs.

Also, to go power fc or Nistune - im leaning toward Nistune at this point in time.

Looking forward to any advice you can offer, thanks guys!

Got a feeling you'll get quite a few responses saying you won't 'need' the Nismo FPR, the Radiator, the head gasket, cams, or BOV for 400 rwhp, and that Nistune is the simple, easy and (visually) legal ECU choice if you're in VIC. Also saves some dollars.

^^^ as above - but if you've got money to burn a 6boost manifold would be better value than the Nismo FPR, the Radiator, the head gasket, cams, or BOV

Will he be happy with 399rwhp or 401rwhp? Can he tell the difference of 5hp tolerance? Specific power goals always amuse me...

No point doing cams and head gasket, you can get that power without cams and I wouldn't bother doing a half job of opening the engine. Just run the 400rwhp until she pops, if she does, and then build up a forged engine.

Some one has to say it did you read the rb25 dyno thread

Also those "Nissan" rear housings by HP in a box suck... plenty of stories on here where people have struggled to make power. Save money by not buying the useless stuff (FPR, cams, head gasket) and go external gate

When I was modding my car, I had 280 in my head as a target. Until I see a dyno give me 280 or more, I'm not stopping. You can't shoot blind. Have a target, aim and shoot.

You have ALOT of unnecessary parts there which are just a waste of time and money. Head gasket? Seriously you're going to pull the motor apart, resurface the head and block, get new studs and put it all back together?

A good bolt on kit will do nicely. You can tell your mate to get a gt3540, that will get him over 400rwhp but how long it takes to hit that power is a different matter. Find your self a nice HKS kit(rare as f**k), or just get a good high flow for about 350rwhp and be done with it.

What are you talking about, got to be at least 50 hp in the head gasket change

[Birds]

What's the point though? Would you actually stop at 278 or completely change a system when you could dyno it elsewhere and get 280. I just don't understand the exact power figures people chase - are you trying to be a dyno queen? Because 280 isn't going to be winning any competitions. I think people just hear about other people having this much power in their cars on the forums and decide it sounds good without no actual knowledge of how fast it will actually be, or if it's even appropriate for their setup. More realistically, you're better off aiming for a specific lap time or quarter mile time and modify until you reach your useful target...jus sayin...

I like that his mate wants to go from "we have a 3' dump/front, turbo smart dual port BOV, Intercooler kit and pod filter to fit up." ( so basically about 160rwkw) to 300rwkw

400rwph is so 2009, 0-100kph in 4.5 secs is the new 300kw

why doesnt your mate come and research... why is it always my mate wants this but Im asking... oh wait is it school holidays again????

and what is wrong with that??

to get to 300rwkw (400hp ~ish) give or take 20kw all you need is a nistune after installing bigger injectors, bigger turbo, FMIC, 3in+ exhaust and boost T..

The other stuff is more to make it more reliable or if the stock parts are stuffed.

The main thing that will make the power goal is going to be turbo. A GTX3076 will make 300rwkw but so can a GTX3071.. HKS turbo mentione above might not make 300 but it sure will kick the other 2 in acceleration on the street. Hi-Flows also might not make 300kw but they make a nice quick 250ish kw which will be fast on the street.

If your mate really wants to crack 300kw then i would not get FPR, head gasket, head bolts and Bov and get a 6boost mani+external gate with a GTX3076
