It's never too much!

Mr331307 had his running at 500RWHP for 8 months, and the only thing that car did was burnouts, drag racing, or dyno runs (Some of the most stressful things you could do)

It was never treated nicely.

Lasted long enough.

Stock injectors too.

My rb25 has 300kw @19 psi for the last 18 months also. No signs of failure. But i do think that she is on borrowed time. 230-240kw should be no worries.

Btw what turbo are you running?

Stock injectors running 500hp?

all depends, you could daily drive a 300rkw standard internal rb25det for 10years...its all about how you drive it. daily drive it conservatively, give it some herbs every now and then should last years...take it to the track and its unpredictable/

since when the f**k did u have a RB25 R32?
Hahaha Gold! Must of traded up on the LTD gas V8.

hahahah nah still got the ltd as a daily

20psi to make 230 - 240kw = you chose the wrong turbo or your tuner is shit.

I have heard that anything over 18psi is asking for a shortened lifespan on stock internals

The car came from japan with the rb25 in it (hasnt been tuned at all in aus), hks 2535, with supporting mods.. but the car atm is running VERY rich.. like ill just rev it to about 4 n petty slats out a bit, so until i take it for a decent tune, she will not be hitting boost in an effort to save petty lol

I was thinking of taking it to DR DRIFT Sam C, i know he specializes in ca/sr im sure he can do rbs just fine, but i have heard mixed opinions about his work, can anyone else recommend a good dyno tune place in Melbourne?

Also, to sort of solve the whole running rich thing, if i disconnect the battery to reset the ECU would that get things running better before i take it for a tune?

hahahha

well the 25 is in a s13 silvia... and std computer, std injectors.. standard everything except for GTR pump... lol

i didnt believe it untill i seen the dyno read out...

neways he is building another motor with gtr rods n pistions...

neways he knows what he wants :)

Is that the 280rwkw car your talking about?

Std injectors & ECU?

Not really, a 2530/2535 is goin to need that much boost.

They are only a tiny turbo, and IMO for a fat mid-range, quite a good turbo choice

the car he is talkin about is mine... it a freak.... i mean i understand that a dyno is only a tuning tool and counts for verry little, but when it backed it up with a 118mph pass at the strip with limited traction til the end of third (i cant drive to save myself on a drag strip) i figured it cant have been far off the money

well i had a look at the computer and it didnt have any stickers or writing on it to indicate it had been played with, and no, no fuel reg. basicly the only thing the car has got it an rb25, delta fin cooler, full 3" exhaust, gt3037 @ 14psi with 38mm external gate with screamer and an old school sub zero plenum. the injectors are stock as far as im aware, the afm is stock, (series 2 engine if it makes a difference. ) but yeh, it does go well

A high flowed stocker (GCG or Slide) can make 250 on ~18psi, so my "wrong turbo choice" statement stands.

My Slide high flow makes 18psi by 3250rpm, makes for a nice fat mid-range.

Very true. If you redline it everyday it wont see christmas. If you take it easy and give it a bit now and then it will last a fair while longer.

if i remember correctly there are a few issues with RB25 ecu's, i think i remember sam saying somewhere about it.

It depends if it is a chipped r32 rb20 or 25 ecu, or a stock or chipped r33 ecu, i cant see it possibly being a stock r33 ecu. In my experience there is no such thing as a freak car, maybe 10 rwkw, but not 50, and ive done 100s of power runs in cars. If it makes that power, it does it for a reason. It appears to have the supporting hardware, now its just the injectors and management, you need to pull the cover off theecu and have a look.

You totally missed the point of what i said.

The GCG is a larger turbo. It has a larger set of wheels.

This means that it will flow more air at a given psi.

A smaller turbo has smaller wheels in it so flows less air... this is bit generalised point but im sure you see the idea.

Saying its a wrong turbo choice is wrong and very mis-informed.

Its like me saying the GCG turbo is a wrong choice for 250rwkw because a GT35 will make that power on 15psi.

See how dumb that sounds?

The GT35 has LESS response, the GCG a bit more, the HKS 2535/2530 even better again.

You cant come out with "its wrong".

    • 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.
