well he said when he had a quick drive it made 3psi at 6,500 rpm so its a top end screamer

as expected.

it would be quite a pig to drive with that sized turbo no matter what size engine.

I think your looking for the word "sic" not pig he's going to drag then swap to a hks 2535 for drift

well yeah, the owner must be crazy to drive something like that.

fyi, the hks gt2535 is too small for the RB24, you'd be better off with a hks gt2835r or the new garrett gt3071r.

exactly the turbo i'll be downsizing to with my 2.4 once i can find someone to tune the fcon V ecu..

my car made 220rwkw on 10psi and insanely rich afr's with the k27 but its way too laggy for a street car (full boost at 4.8k). basically useless in the hills unless your on gorge road (open mid speed corners).

:blink:

Hi guys i live up here in darwin (bloody hot) ive got a rb20det in my s13

ive got: GT25-40

550cc rx-7 injectors

microtech ltx-8

gtr fuel pump

shitty stock supra front mount

press bent intercooler piping...(dodgy)

3" exauhst with trust 4"tip

currently running on 12psi it made 209.7rwkw (indarwin and yet to be tuned)

i just blew the motor up about 1 month ago and now ive got HKS cams tomei head gasket 700X350X100 Trust FMIC and im looking for a forge kit but cant find ne thing for the rb20 should be making 250+ once i get it running properly, only prob is i cant run too much boost up here because of the heat.. :)

Also my best time at the street meet was [email protected] track temp was 34degrees on the night! on street tyres :)

dude,

Tomei in japan make forged pistons for the RB20DET, although to suit over-bored application, check it out;

The GT2535 would probably quite a very nice street RB24DET.

i just feel that the turbine wheel in the gt2535 is too small for any engine that has a capacity of > 2.2L.

it would choke power up top given they run larger compressor wheels.

just my 2c

RS500,

It does no doubt choke up top end but thats exactly why I think it would be awesome for the street. Lots of mid range torque, there's nothing worse on the street than having to ring the crap out of it to zip up the inside lane or to overtake. It really depends what your used to, I'm used to big lazy v8's and old lazy 6's with lots of low and mid range torque.

Seeing how the GT2535 works on the rb25det's makes me think it would most definitely work very well with the rb24.

you make a good point cubes, although by running a turbo like the garrett gt3071R, the larger turbine wheel will bring the smaller comp wheel into efficiency earlier without the lag experienced with a turbo like the HKS GT2540 for example.

less back pressure in the exhaust housing would allow the turbine to come onto boost earlier than normal inturn producing more mid range torque, plus the fact that it doesn't have to spin up a massive comp wheel at the front.

no love for the RB20 here (sorry again Roy).

Blitz front mount

A'PEXi pod

3" turbo back w/ hi flow cat

upgraded fuel pump

running 12psi got me a massive 138rwkw....RB25 here we come :)

arent R32 GTST and GTS4 meant to be 165 kw stock ? how can ur power be so low ?

165 at the flywheel, about 110-120 at the wheels so hes doing better then stock. The old redtops rated at 140 only made 95-100atw in stock form, slower then a rb30e.

    • Hi. This is just my curiosity because iam sure the tuner figure something out...but either way i want to ask. The "problem" is that the Nistune ECU (Stagea FW and RB25DET NEO from Stagea) sees many times the speed than the speedo does(he says the speedo show 120 km/h - correct speed and the ECU shows like 510km/h ) I told him that this car/tranny getting speed from rear diff. If iam not mistaken the RB25DET NEO "need" to see tranny speed sensor? (my tranny has the plug for it). So couple of "question" If he connects/wire the speed sensor to the tranny...are the signals gonna intervene and if...what if he disconnects the rear diff one and the speedo stops working? Or the "new" sensor from the tranny "take over" and will not going need the one from diff? As i said i know he figure/get that done...iam just curious to know what are the solutions 🙂 
    • Your IACV is set to idle too low. You need to adjust it via the screw Duncan mentioned. From memory it should be 650rpm with the valve electrics unplugged. What is it trying to idle at with the IACV plugged in?
    • Ahhh, I need the whole head unit. I definitely needed to roll back through and review your setup, ha ha! Neat setup they have going on. I just need a full double din head unit. But I want good and responsive. I might have to review what the likes of pioneer have out these days.
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is may e 1 wire in the ecu plug I need to move to rectify this. Dose anyone here have any ideas?   Cheers guys
    • Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?
