Hi guys

I have a 91 R32 GTR, has a fully rebuilt motor to all N1 specs. N1 Turbo's, N1 oil/water pump etc etc. Has 1500km on it. Also have a 3'' exhaust and HKS Pod filters. I'm getting it fitted and tuned with some parts soon. Feels like its runing stock boost at the moment. So not sure how much its making.

Apexi Power FC pro + Hand Controller

Apexi Boost control kit

Nismo fuel pump 276 lph

Nismo fuel pressure regulator

Sard 700cc injectors

I'm just wanting to know everyone opinions on what kind of power I will make at the wheels once I have this work done. Since I have the N1 turbos, I'll probably be getting it tuned at 15-17 psi. I Heard i'll make 250rwkw+ and then heard from other's I should crack 300rwkw.

Your thoughts???

Around 265 depending on exhaust restrictions.

Only one way to tell for sure - tune the thing and come back with a result. Then put it in the RB26 dyno thread which is up the top of this section.

N1 is not all forged.

If it's been build to strictly N1 specs - it will still have ALL the problems that RB's have factory especially around oil control etc.

Basically you need boost either way - read the dyno thread.

Yea sorry, didnt mean all forged, just ment Pistons etc. Yea fairly sure its been built to proper N1 specs. Ohh, I really hope I dont get all those RB" problemsthen haha :(. Boost it is. Hopefully 18psi will be comfortable for it.

I bought it, and the guy rebuilt it all to N1 Specs, inlcuding turbo's etc. I dont think he did the oil system which would of been smart, just has gthe N1 oil pump etc. so that's why I thought 18psi is probably enough for it. Has only 1500km since the rebuild. But you guys would know more than me.

Just wanted to see what kind of power it will make with those mods, and it looks like high 200's. maybe 300rwkw with 18-19psi.

Mine made 400rwhp at 18psi with R34 N1 turbos.

Same.

91BNR - you should have no problems getting 300kw, and you shouldn't need to add any other parts to get there. The only thing you could add is adjustable cam gears, to help low end response.

yea I thought about cam gears, not sure if really needed them though. How about the Stock R32 GTR AFM's. will they flow 300rwkw? I mean i don't wanan keep spending more money than I need too. Gotta draw the line somewhere lol. and 300rwkw would make me happy

Those turbos+ 700cc injectors and standard afms should net you 300 rwkw.. Standard afms start maxing out at around 310-320 mark

Make sure it's a safe tune, dont bash the limiter, service the engine properly and enjoy

Who's tuning it btw?

Stock injectors will be fine as well. They will run out 280-300rwkw as well. Spending $700 on injectors and not doing the AFM's is a waste IMO.

If you run out of injectors, just up the rail pressure a bit. I've managed 340rwkw out of stock injectors via a very tiny bump in the pressure. Wouldn't go any more than that but it can be done and reliable.

Thanks for the advise guys. From what people are saying, I might just leave the standard injectors and AFM's and get it tuned at 16-19psi. And just see what I get. The injectors have been Sonic cleaned, flowed & tested with new caps, so they would atleast be in good healthy condition. And the AFM's have been properly cleaned aswell. If I get close to 300rwkw with that I'll be happy. As I am on a budget, no point me spending another $1200 if my injectors and AFM's are holding up well at high 200's/300.

= See what I get for now :)

Would people agree that if I wanted to go furthur after that, it would be 700cc injectors, Z32 AFM's and Cam gears?

Cheers for all your input, helps me out alot.

    • 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. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
