Decided to just dump the 26 into the 240SX (200SX).

Heres the mods I will be running:

R32 GTR Motor (Possibly R33)

R33 RB25 Tranny

Aluminum Single Peice Driveshaft

Hardened 4.11 Rear End Gears

Kaaz 1.5-Way LSD (still debating which to use)

Blitz Skyline FMIC w/ Custom Piping

Apexi Intakes w/ Cold Air Induction (try to encase the filters w/ box, if not I'll just duct ambient air)

Blitz SBD iD Boost Controller

Blitz Auto Timer

3" Custom Downpipe to 3" Blitz NUR Spec Exhaust (no cat)

Haltech E6K Engine Management (moderately tuned for power, still want car to be somewhat reliable)

255Lph Walbro Fuel Pump

RX7 Oil Cooler

I believe thats about it for the mods. Im going to use stock turbos for a while and later upgrade to twin HKS2530s.

I'd like to run about 1 bar if that is safe on the fuel system. I very open to opinions and suggestions. Let me know how this stuff works out on your GTRs.

I'd like to get an estimate of what kind of power I would see at maximum SAFE boost levels. I'm perfectly willing to sacrifice power to maintain safe engine operation.

I need a suggestion for a clutch as well.

Thanks guys!

Figured since the 2530s can flow around 320 ps each I would get around there. However I was more or less wanting to know what I can acchieve on stock turbos. Also what kind of boost limits I would see with the stock fuel system (w/ 255 lph fuel pump) and stock turbos.

I think the most you can get out of stock turbo's is 400hp'ish don't quote me on this..

As for your fuel just because its says its 93 octane doesn't mean its worse then ours, in the states they use another method to determin the octane rating so your 93 octane is probably better then our 98 octane stuff.

Dunno... probably the same? WRXs get away with 14 psi on this "93". One of our gas stations underrates their gas... its 93 octane via label but it sure smells more like race gas than pump gas. It hasnt been tested but word is these stations have around 95-97 octane instead of 93 octane. I dunno, it doesnt seem logical why they would put higher quality, and more expensive gas and sell it as 93.

Before I go and spend 10K US ... I wanna know what it will put out, ball parked at least. Im more or less trying to figure out what the motor will output at safe boost and what safe boost is. Also general output numbers work well for tuning. If I get the car up there and make 100 hp short of what alot of other people are getting then I know there is something wrong with the motor and I need to find out what it is.

      Mistakes were made, my R34 Story

      (it is a brand new ported mellings pump) I suspect the lack of pressure is due to the leak. It was *not* that low in other logs of oil pressure in the past. It wasn't that hot either, but not far off.

      Would a Mellings oil pump be a viable option  From my time with a LS, and talking to tuners and LS specialists, the "weak" OEM oil pump is one of the first things they recommend to swap out if I was going to give the engine any high RPM I opted for a Mellings high volume, with the high pressure springs and I never had a issue with it Cost wise they are not expensive in the scheme of things

      Just bought a 2002 Stagea 250tRS VR-X Four AERO VQ25DET and spent the last two weekends cleaning and detailing it.. still have to do the wheels and the engine bay but the rest of it came up nice. Imported 2011 to S.A. and I'm the third owner since it was imported. I met the guy who brought it over, he went to Japan and picked out the car, bought it and ordered the wheels. He also gave me a list of stuff he did to the car with receipts. Coil overs (I have the original springs), 3" exhaust from the dump pipe back no cat, Custom dump pipe,(I have the original exhaust), Plenum spacer, 18" custom Work XSA wheels (need restoring, I've made a start..), Shift kit put through the 5 speed tiptronic auto, TV and menus/screens changed to english, Australian DTV tuner installed in rear. I've just had four new discs and new pads as well as all the fluids including the brake fluid replaced. I have all the receipts for the last 15 years and the import papers in a nice folder. Car looks great, goes like hell but fuel economy is not a thing lol.. pics next..

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      I ended up in this rut again lol, and used a shit ton of filler. One thing I can't understand is, even after using a big long block and going in long X pattern strokes, I always end up at bare metal again with no filler, and my repair started at one end of the door and now I've chased my tail to almost the other end of the door. I was thinking of hitting the panel with a hammer where it might be a high spot and making everything low then filling it, I did this on a small section on my other door by mistake and I think I fixed it lol. Is this a bad idea? The other thing is with guidecoat, whether it's the powder or spray, after I sand all the guide coat off, it doesn't reveal anything for me in terms of high spots and low spots and makes it especially hard when it's bare metal (at least in powdered form), am I doing something wrong here, or likely a high spot I keep going over and creating valleys? Lastly, stupid question but, is it possible that after sanding if I only sand over the filler area where I know to be a dent that it's impossible for me to dig into that dent? Unless there are other problems which I missed.
