not sure of the exact specs denham

but its got a pretty huge ex wheel and housing on it

on my mates sr20 he runs 26psi but his has a smaller housing and wheel on the back - makes bout 300rwkw

i know that there r other turbos out there that can make that power at lower boost levels - but when ur paying 900 for a brand new t04 what am i to whinge :P

  • 2 weeks later...

no its chromed its all a bit dirty at the moment and not quite finished but its working out well so far boost response is alot stronger and im having heaps of fun with the external wastegate pipe and pedestrians. the gf rekons it sounds like its goin to hurt someone or sumthing

here she is all bolted back in place.. car goes as well now as it did before on 13psi now only using 9psi so im happy tune up will be soon ill keep you all posted.

Did u manage to hook the 2 springs onto the clips with your xtr thermal blanket?

I am having a bit of a problem getting my to clip on

Hi guys, a lot of people look at the other upgrades (cams, porting, manifold etc), on a turbo car, as a way of increasing the maximum power at one particular rpm point. That's not what I do it for, I actually use these other items to increase the average power over the used rpm range. I also use them to reduce the amount of boost I run to achieve the same maximum power, this increases the responsiveness of the engine as well.

A comparison;

1. I have an RB engine that needs 1.6 bar to achieve 600 bhp with standard cams, ports, lowered compression ratio (thick head gasket) and a combined dump. It has 360 bhp average power (4,000 rpm to 7,500 rpm).

2. The same RB engine that only needs 1.3 bar to achieve 600 bhp with 264 cams, ported, manifolds matched, standard compression ratio and a split dump. It has 440 bhp average power (4,000 rpm to 7,500 rpm).

Some people would say that I wasted my money on the cams, porting, split dump etc since I still only have 600 bhp. I would of course reply yes, but I have a 22% increase in average power, so the car will be substantially faster. Plus the response will be also dramatically improved by the enhanced breathing, with better off boost performance and faster to build boost.

Hope that makes sense.

sure does

ur peak power stays the same but ur power over the rev range to acheive that peak power increases

torque would increase over that rev range to achieve a faster car lower down, resulting in a faster car at higher speeds

correct?

    • Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.
    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
