Short list of mods:

RB25det spec 2

GT3582R .82ar

Jun style intake

90mm throttle body

550cc Delphi top feed low impedance injectors

JGY fuel rail

Aeromotive FPR

Walbro 255hp fuel pump

Tial 44mm v band waste gate

Hallman boost controller

3" ss turbo back exhaust

Top mount exhaust manifold

Apexi Safc 2

Apexi ITC

93 pump gas

Spec stage 3 clutch

Synchronic BOV

FMIC

Z32 MAF blow threw

This is a 2698lb with driver in it 240sx.

We had some problems with the boost creep so we could only set it at 11 psi but as you can see it creped up to 13.5 or so at about 6100 rpms. Also had some problems with my coil packs.

This is wheel horse power not in shoot out mode.

Correction factors were

77deg. F

60% humidity

60" of mercury

Intake temp was 90deg F

Car pulls like mad all the way to red line. I am very happy with the car as is but I'll more then likely pull the exhaust manifold off and fix the creep problem.

Was not sure of the amount of boost I can run on a stock rb, so we kept it safe at 13.5. What would you recommend? What can these motors handle??

I am going to be pulling out the motor this fall and building it top to bottom. To take advantage of the set up. SO If I can run a higher boost now let me know!!!

Seems like a bit of a waste until you turn the boost up.

Will the stock motor hold up at that amout of boost?

about 20psi depends if you start to get valve float those turbos can run up to 30ish psi. Not sure how well a SAFCII will go just keep an eye on A/F dont get leaner then 12ish to `1 when you are leaning on it.

I had asked my tuner if I needed to get a power fc and he told me with the itc and the safc2 I would not see much of a difference at the level I was running the car. I'll check with him again when I get the coil packs and see what he thinks about running 17-20psi.

I just can't see spending over $1300 U.S for a used Power fc. Then having to spend another $300 to get the tuning software! If need be I'll just get a haltech.

Thanks so much! I am way more familer with US market engines. I.E the VQ35, 4g63, 2jz and the like. I'll have to put the money out on a good set of coils first then it'll be a haltech!

Thanks again guys!

I'm happy with the power it's making now as the car is light. Can't wait to get a Haltech, coils and fix the boost creep!

then get a haltech any standalone will be much better. Yes stock will hold you may need to put a metal head gasket on though. Like I said at that boost some people have valve float issues.

whoops its a gt35/40 (for some reason thought it was a gt30/40) so i would only run the car up to about 300rwkw unless you want to put some forgies in then you can crank the boost push the car well into the 300rwkw range

so thats about 402whp. Sounds good!

I've noticed on the dyno thread for the rb25 that alot of guys post up the shoot out mode on the dyno graph. Not sure if is the same as what my tuner is calling shoot out mode or not. Could someone clear up what Shoot out mode on the Dynodynamics there means??

My tuner is telling me it's crank hp. Is this what you guys are calling it??

    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment.
