yeah im think going a sard fuel reg, then different injectors.. mine are getting super noisy anyway.. esp now with the manifold cover off.

What bigger injectors did you get and how much were they, and did you require any fuel rail changes other than the injectors ?

who are ATP ? i take it theyre in victoria?

No point doing anything until you can tune it, Emanage is the only option at the moment...

ATP are in Melbourne but GCG will do one for you mate. Injectors are Seimens Deka 610cc, $450 a set.

why low comp? Up the comp and go E85 if you want HP!
E85 is not available in NZ - E10 is the only readily available fuel unless you want to pay for Q16 which is not that convenient and also expensive.

Re engines: Simon, who built the 600kw "Psymin" Stagea has taken all the good gear out of the car and put it in an R32 GTR which as you can imagine is even faster. He says that his next project will be with a VK56 (5.6L dohc V8).

You could always brew your own. :(

Can get C16 in NZ, which is race fuel, but its not cheap and ready available for road cars.

Yeah that Stageas insane, i'm going VK45 for the reason being there's alot more available for them at the present, so a cheaper choice.

I havent seen many performance parts getting around for them, of course I dont go looking much. Heavier and longer engine will upset the balance, you going rear drive?

Cheaper choice, is that like choice bro? :D

Thanks for the injector info!

Yeah i gathered other than the ecu upgrade.

so whats the variable with the nismo ecu's ? dont tune as well?

i take it these are piggybacks on the original ecu?

and GCG - i take theyre from the coast ?

i really need to take this step and getting a decent ecu.. i saw a nismo one on yahoo auctions for $500

GCG are in Sydney. I presume Nismo ecus are like Mines? Just a chipped stocker and not tunable? I see someone with an M35 has an Impul -is that tunable? Greddy E-Manage is tried and tested so should do you OK. BTW if you are upgrading the injectors forget the new fpr.

Bob is right.

I need a fpr for mine, not just for the extra flow, I will be going down the surge tank route and I want to run dash fittings with teflon lines. Apparently the ethanol will eat the rubber parts eventually and I want it reliable. You shouldnt need a fpr till well over 350kw on 98.

If we were in Japan, all the aftermarket ecu's would be fine as they are programmable but obviously we cant take our car to impul for a tune. Best options are FconV or Emanage Ultimate. Tuners are few and far between for both but the emanage can be accessed by you with a laptop, pretty sure you need a licence to tune the HKS.

you know I have the parts list to do the top of the motor don't you....+ the map :D....for the fuel system that is.

how much HP you chasing.....I would only go to about 400hp with the GCG BB set......morer than that go the Garret BB set.....bit more modding but well worth it if your looking for 450hp+

better still if you go E84....go for Scott's setup!....cheaper and works very well!

Cheaper choice, is that like choice bro? :D

LOL! Naah

Yeah will be rear drive, my M35 is rwd now.

Will mostly be custom parts, the good thing is VK is slimmer than VQ so turbo setup is easy to do without having to cut bonnets and go crazy with manifold setup.

And my uncle owns a hotrod shop, so he will wana get his hands on it, cheap work!

After ripping the turbo and exhaust manifolds off today I test fitted them to the VQ35, they fit perfectly. The 35 has larger ports but the manifold is already the right size, not that I will be using them. It also looks like the 3.5 block is the same as the 2.5 block, just with larger sleeves.

I then test fitted an old GT35 I have and although close to both sides, it will fit no problem, (definitely need a turbo beanie though) so the project is going ahead as long as the sump fits...

Sounds awesome mate!

no wonder the vq25 blocks are so good!

    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies. 
    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
