Hey i'm about to buy a new turbo for my 93 sr20det silvia. Just wondered what you guys thought would be the best streetable turbo. I was thinking a HKS 2530 or 2540. I don't want a race car, or a drag car just something that will spool up quikly and do mid 12's. I'm open for any suggestions provided they meet all my criterea..

thanks guys.

or HKS GT 2835 has a bit more torque range and a better liner curve... rather than top end power.....

i mean let's face it.... we dont always hit rev limiter in all gears...

just sometimes :D

they are ideal for 2 and 2.5 itre engine's....

and munro has two on his 9 sec GTR....

but that is only a small part of his development.....

here are some specs

When I was looking to get an aftermarket turbo for my silvia (now sold to make way for skyline) I thought well and hard about getting a full aftermarket turbo such as a 2540. Had a chat to a few people and some were even kind enough to take me for a spin in their cars so i could gauge for myself. However I came to my own conclusion that I would rather buy a second hand turbo off an S15. They are steel wheel and ball bearing flowing 320hp in stock trim and can be picked up for around $600. Was planning on getting one of these then paying another $1000-$1500 to get it HI-Flo to 420hp. Not a bad price no external gate required and bolts up to same mainfold water and oil lines same fittings. Not seeing a problem here, just something to think about. hope this helps.

    • Have you done the Ignition Sync Wizard in the AEM software?
    • Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...
    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
