gcg said they could do a t3/4 that was not ball bearing for 1800 i think, but if you just go a stock turbo you know what youve got and even if its not right you havent spent 2g

Meggala I just got a hks t04e to put on my 32, only cost 400 and I am modding the stock manifold to take the extermal gate, do you have any info on the turbo, hp rating boost efficiency range etc, thanks.

hey clint its a treeible turbo you don't want it .

you will have to send it straght to me

:lol:

as for info it depends on the the a/r ratios etc.

btw I wouuld love to see pic of the manifold when done

400 hp would be a good guide talk to adam32 as he has one on his r32

meggala

its got a .6 ar exhaust and comp housing, not too big, about 59mm exhaust wheel i think.

the manifold is not as easy as i thought as there is not much room, i was going to do it like the jms onveia but there is less room in a 32 so the plate has to be angled to clear the strut tower. will take pics once its done wont be for a couple of months, as im dooing the inlet manifold as well and need to buy rx7 injectors and the wastegate.

Joel,

You know Tim at RPM pretty well so why not consider the GT28 400HP unit for RRP $2300. It has a small exhaust A/R of 0.63 so spool up should be good. 4" inlet and 0.7 A/R compressor should also give you 200rwkW easy.

All you need is the spacer for both rocker cover clearence and also adaption to the T3 flange.

Basically Tim can only do the T28 or the GT2510 which will only make around 180rwkw.

SO... I poped around a few places today found a HKS EVC which is a dual solanoid and has the rpm thingo and also a map sensor.

Then I came across a jap importers that is getting in a GT2540 next week that is from a GTR, he is splitting them as a friend of his wants one for his SR20.

I might put up with a bit of lag, it really depends if my injectors do end up being bigger than std. If so here I come 2540.

clint32,

fyi, the HKS T04E is actually rated at 500hp and would be perfect for an Rb20DET engine. a little laggier than the standard turbo but power/boost would come on quite hard.

check out the following link, it should give u all an indication of the hp ratings fro all the turbo's mentioned.

btw, a friend has a 400hp GT25 on his R32 RB20DET, along witha FMIC, unichip, and bigger pump and it's producing 222kw at the wheels on 18psi, with heaps more potential.

i guess it all depends on what u want from your car joel.

//RS500.

Joel, what turbo did you end up getting, or are you still deciding?

Have you spoke to Ben at Tilbrooks (Brains) He has a R31 wagon with a HKS 2530 on a Rb20, been in Zoom etc. That car goes pretty hard. It makes around 220 at the wheels, but being auto with 2500rpm stall, I don't think lag is to much of a problem in that car.

I think that fact remains that any bigger than stock turbo will be a bit laggier, but the trade of is consitant boost right up to the redline

I am in the process of getting **** toghether with my car for a bit of a power-up, including turbo, bigger intercooler and maybe new injectors or pressure regulator on the existing ones.

Let me know how you go

Chris

So, just how laggy are these turbos (hks 25 series) ? as i just recieved my gt2535 today and would have thought being a BB turbo and still being reasonably sized it should be quick to spool up. I thought i should have full boost by about 3500 rpm.

My turbo has a .60 a/r compressor and a .64 exhaust housing.

    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option 
    • You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
    • I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
    • Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
