Hiya from the US... shamed not to see a Chevy Z06 on that list of cars you want. Either way... I drive the US Silvia varient, dubbed the 240SX. Its a 96 S14 and it has the 155hp/160ft.lbs. 2.4L N/a KA24DE motor, yes we got jacked on the motor deal! Alot of people here swap the SR20DETs into their cars, but I find that to be boring and plain to be just like everyone else. So Ive decided to swap the RB25DET motor into my S14. I know only a few things about the motor and the whole intention of me being here is to learn about it. I am aware of the turbocharger's downfall with the "plastic" compressor wheel and the ceramic turbine. Although its not too much of a bad thing since it should spool incredibly quick with an inline-6 and such lightweight internals (refering to the turbo's internals). Either way nice to find this forum. Oh and some dyno gains whould be nice!

Be wary the RB25DET is a lot heavier than the SR20DET and will make the S14 of yours understeer a bit more.

Also I've only heard good things about the S15 SR20DET - it has an almost completely flat torque curve unlike the RB25DET which has stuff all power till it gets above about 2500RPM... But when it does, it boogies :)

S15 Motor = 3000-4000 US

RB25DET = 1000-2000 US

Plus the SR20DET is too boring for me. Doesnt have that inline 6 growl and there are 8 people in my town alone with that motor in their 240SXs.

As for the weight... im getting Tein adjustable coilovers with custom spring rates to accomodate the new weight. I also will be relocating the battery to the rear.

Hi Nismo_Freak...

You're right about the factory turbo, it spools up quickly and delivers good pressure. Try and get a series 1 turbo cos it is stronger than a series 2. Bottom end torque is not that bad but of course once the turbo starts spooling at 2500rpm the power kicks in.

      From Japan and back to Europe, my sh*tbox R34 GTT

      Yeah, I get that. I try to be as cost-efficient as possible with cars, and typically prefer to buy them at the bottom of their depreciation curve. I was looking at those Bilsteins too as they're roughly in the same price bracket as the BC's - lack of adjustability and being soft put me off, not that I want anything too hard. That's my issue with the Skyline, it's too expensive and it's reflected in my driving. I don't mind going full pelt as long as there's a gravel trap to catch me. Really, proper safety equipment is needed for total confidence. Well this just turned up for the BMW. I'll try and get the front together tomorrow and take some pics of the absolutely horrid rear end; perhaps I'll have a crack at the rear on Wednesday. I need to make the car drivable before the weekend as I'll be driving it over to London.

      It does sound like a fuse considering the indicators work..I’ll triple check when I’m free and report back.    thanks for the reply.

      R32 GTST - 600KW+ RB28/CD009 Build

      While going through data logs late last week, I spotted a small issue with my WMI. My WMI starts to progressively inject at 11psi of boost. I'm using a 25psi cut in pressure switch on my WMI as an added safety and if the curve is linear, I should hit that 25psi on my WMI system around 13-14psi of boost.  As per my data logs, my WMI pressure switch only activates around 19psi of boost. This is causing my non WMI 4D map to trim for WMI. I'm presuming this is caused by the mechanical switch response time, injection curve not being linear or both.  I ordered a 2-10psi adjustable cut in pressure switch which should correct this. If this doesn't resolve it before my dyno appointment on Friday, I'll just remove the pressure switch temporarily and more than likely replace it with a pressure transmitter afterwards.    BTW Speedtek has yet to refund me.
