how much $$ for 500 hp?

[NismoS-tune]

Here is what I have done and I can tell you it was a little more than 2k in mods:
-rb25
-725cc injectors
-dual entry fuel rail
-upgraded oil pump
-greddy intake manifold
-q45 throttle body
-top mount turbo manifold
-going with a billet turbo a little bigger than a gt35
-external waste gate
-custom downpipe
-aeromotive fpr
-tomei fuel pump
-yellow jacket coil packs
-greddy fmic
-tomei belt
-tomei head gasket
-arp head studs

And there is more but I can't remember it off the top of my head. I don't know what kind of power I will hit but I can tell you one thing, next year I'm doing forged internals and making sure the engine is done right! Rb motors start to take shiits at anything higher than 500hp so be careful. Also man with an rb26 you should be able to hit your goals a little easier than me but I imagine the awd will just rock your world at that power.

I'd guess you'll be ok with 400whp, especially on a questionable 20 year old engine.
And what do RBs shiit after 500hp,other cars?

Once you take a drive in a 400AWHP you'll quickly realize how intense it is and you really don't need a ton more for a DD/weekend track machine.

This is absolutely true. I got a ride in an R32 GTR that I believe the owner said has 275whp on a mustang dyno (300 and something on a dynojet I guess?) and that car HAULED. Like, fast.

400 would be... Scary.

[doublejceballos]

I agree with falcons last post

if you could have a ride in a 400 AWHP GTR
you'd soon realize that its plenty to have fun with.

actually you'd probably shout some expletives and then be like

[GTRADDICT]

five. billion. dollars.

okay falcon thank you.
i will do that 400-450 hp seems more resonable ive been reading so i think ill just aim for that.

2000$ with a few bolt ons and 150 shot nitrous

70,000$ with a Dry sumped, V-cammed, OS giken rb30 with a new EFR 7670 and a motec m800

a better idea is start with a budget and work from there

Sick build you got there mang.

Some of my friends say that you should only run at 80% max for reliability, dont know if thats true or not.

Anyways heres tyndagos 500 hp-

Advanced Modifications (500 – 550 horsepower)

Intake($300 - $500)
Exhaust($700 - $1700
Downpipe (frontpipe)($200 – 500)
Twin plate clutch ($1500)
Power FC , Commander , Boost Control kit ($980 , $350 , $380)
xxxx(I think stock is ok) Intercooler upgrade ($700 - $1500)
Fuel pump ($450)
Transmission Upgrade ($3000)
Camshafts ($1000)
VG30DETT MAF ($780)
Twin turbo upgrade ($600-$5500)
Port exhaust manifolds -
Fuel Injectors (720 cc) ($1000)
Cost : $11,940 - $17,950........................................... .....

[falcon]

rule of thumb: rougly 1hp at the crank =1cc. 600cc = ~600hp at the crank give or take thats pretty close to 500whp

I don't agree with this calculation. Zulu's GTR was running 700CC SARD injectors and at 28PSI and 528AWHP the injectors were practically 100% duty cycle. I think the math is a bit off, I would say 600CC is closer to 475AWHP.

falcon layin' down the smack down.


You can't just add power mods, you have to do all the peripheral/support mods as he said.

gotta pay to play in this game.

[falcon]

i dont want to do it the cheap way, i want to do it the right way.
and i already had a r32 gtr i know how hard they pull just when i get my second one i don't want to leave it stock
im just aiming for 500 dosnt mean that ill forsure go that high.

Let me put it this way. I helped build a 528AWHP GTR a few years ago. It made that power on twin GT2860r-5 turbos, N1 block + a bunch of other stuff like Tomei manifolds, SARD injectors, ATI damper, R34 IC, OSG twin plate, Tomei rear diff, PFC + gauges, fuel rail, FPR, pump etc. etc. etc. He spent upwards of 15k and it still blew up in the new owners hands when it was sold.

You want a RELIABLE 500whp, be prepared to spend 20k and you need to take into account the clutch, front diff (known to blow up), blowing up trannies etc. Plus all the small details. Hell, I've done a pretty simple build on my Miata and have spent over 10K already. And I don't even have a power adder yet. That's just the motor + peripherals. And parts for Miatas are CHEAP compared to Skylines.


Here is what you need to do for a basic 400-450whp build that won't break the bank too much.

1) Toss the turbos and pick up some GT2860R-5's. They are the "go to" turbo for GTR's. This will be the most expensive part of the build. Quick spool, great power potential (made 528AWHP on 1.8 Bar on 91 Cali **** gas). The turbos still had more in them but the injectors were maxed.
2) Get engine management. Don't get a piggy back. You will regret it. PFC is the go-to here.
3) If your bottom end it healthy, pull the head, throw some ARP head studs on, deck the head, metal headgasket and put it back together.
4) Pick up some 600CC injectors. Leave the stock fuel rail. It's fine. Get a FPR (NISMO works fine, stock one oscillates too much), and a fuel pump. Don't need to go crazy here. A Tomei or Nismo pump will flow enough for 500whp.
5) Get a clutch. You're choice here
6) Get a new coilpack harness, buy new coilpacks as well. Spark blow out sucks
7) Get a downpipe, keep the stock intake pipes they are fine. Get filters and Z32 MAFS.

And the most importaint step. Get a tuner that will NOT blow your **** up. A good tuner will know when he needs to stop pushing the motor and the boost. Key questions to ask your possible tuner. Do you know what "MBT" is? (google it), Do you tune with detcans? (again google,) If the answer is NO or they have no idea what you are talking about. Keep looking.

What I listed above will not break the bank too much and make a solid 425-450WHP. The limiting factor will be the block. Don't push the turbos too high, you will need some self control. Once you have money, build a block and go nuts.

The thing with RB26's, it's easy to make 400-450whp. The last 50whp to get you in the 500whp club is what will cost $$$.. Also, where you see WHP in this post, refer to it as AWHP. 525AWHP is way more than 525RWHP.

[bobbo]

Stop being a leech and do some searching. God knows ALL the information you're looking for is on this site.

And I will give you a high five if you can make 500whp on a $2000 budget. HELL, I'll give you an extra 1K. Get it done for 3K and you are my hero.

Good luck. lol

+1
I got a good solid running GTR. By the time I built a good reliable base (coils, coil harness, plugs, good clutch, brakes, changed the fluids ect.) I was over $2G.
You have to consider you have to spend a minimum of $400 for a piggy back then another $400 to tune it properly. Toss a tank of gas in there and your budget is already 1/2 gone and your at roughly 300-330 hp.
