G'day, ive got an r32 gtr with the following mods, what should be my next upgrade, im guessing turbos as these fuel systems are good for around 400rwhp correct?

Apexi full adjustable computer

3.5" exhaust from turbos back

Blitz EBC

pods

thicker intercooler

exedy hi performance clutch (very heavy clamp load)

I'd be looking for around 400hp at the tyres without pushing it too hard.

The car made 226rwkw (308hp) @13psi with a mines computer and it was just before the bottom end let go, now has a fresh rebuild.

Also any approx pricing would help.

thankyou

injectors are good for around 400 engine horspower (with a fairly fat tune).

i would not think you can safely get to 400 rwhp without upgrading the injectors, and the fuel pump. considering you've already been through the rebuilding process i wouldn't want to risk it without them.

for me i reckon the limit on the stock 32 GTR stuff is around 260 or 270 rwkw.

i reckon next step power wise should be:

injectors and pump

cams

turbos (something like R34 N1s, or GTSS or 2530s)

do it all at once, retune and away you go.

by this do you mean the turbos will push 260rwkw?

I also forgot to mention, it has a nismo adjustable fuel reg

sorry i meant stock fuel system, and stock turbos being looked at together. but yeah, stock turbos are not good for much more than 260 or so in my experience. perhaps with cams etc you could get to 270 or 280. injectors will be marginal though at that level.

Cut to the chase :

TO4Z

Forged internals

Upgrade fuel sys

cause everyone has a lazy 10k sitting around.

Nugget, you will get 300rwkw with stock injectors.

Ferni is making 300rwkw with GT-SS and stock injectors.

But that is the limit of them.

I wouldnt reccomend bumping the rail pressure (with that fuel reg) to be honest.

GT-SS (my thoughts) are the way to go if its a street car, with a fuel pump and injectors you'll get into the 320-330rwkw mark,

Will get you into the 11's aswell i believe

Why type of rebuild ? (i cant rememer your post on CalaisTurbo about it all)

yes, i'm sure 300rwkw is possible on stock injectors and pump, but on a 10 year old + 32 GTR i wouldnt think it's a good idea. i would definately upgrade if you are doing turbos.

the advice is sound though about doing the SS and turbos etc, but i must say i'm blown away by the 240rwkw before 3000 rpm!!! that i would like to see. i've never seen any 2.6 litre RB26 come close to that power at 3000rpm, but i am intrigued as it would be awesome. and more details on this motor?

Ah, fuel pump for sure, wasnt disputing that at all, totally agree on it.

Its ferni's... most of the other GT-SS guys are making that aswell...

Or maybe it was 10psi on before 3000rpm, oh god... ive got myself into confusion again ;)

i'll edit the post, i cant damn well remember at the moment, dont wanna confuse anyone else

"unless" im mistaken, which is highly likely... either way... its solid respons regardless of how you look at it heheh

haha yeah, 10 psi at 3000 sounds more like it. 240rwkw at under 3000rpm would be mind blowing! i'd be shifting up at 4000 all day long ;) lol that would be a farking quick GTR.

it was just a standard rebuild

so your limited as to how far it can be pushed... thats ok, GT-SS fall into there quite easily (worked out im a fan of em yet? ;))

you might not need cams right off, i'd see how you go first

well i have about that now. stock turbos at 14psi, power FC, cam gears and a cat back exhaust (at the least) will get you there with a good tune of the PFC and the cam gears.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
