No problems running "moderate" upgraded terbs with the std ecu. You will start to approach the limit of the std injectors and prolly also be near the limit of the afms.

Check the a/f ratios on a dyno, however, to ensure all is OK with fuel supply however.

gtrken on these forums has prolly done this a squillion times before and could offer more advice.

fyi,

a friend of mine ran the N1s on his RB26 with the standard and everything was fine, although he only ran 12psi, and it went quite hard.

i believe he is selling these turbos atm, so if you're interested PM me and i'll pass his details onto you.

lazza ,

dont bother with the stock ecu , they will run fine but very rich , got them in my gtr .

get a pfc get it tuned and you will have an 11 second car just with turbs , pfc and a good exhaust . thats all i've got and i ran 11.7 @120mph at wsid . when i had the stock ecu i had nowhere near the power that i have now and i was getting 300 - 350 km per tank , after pfc and a tune i'm getting 450 -500 k per tank and i can loose traction on a dry road in second gear when it comes on boost on the stock 17 X9 's with 245x45 tyres

Does it matter?

Oh yes, the R32 ECU can be tuned in real time on the dyno fairly easily. You get pretty goods results from a mild R32 GTR by tuning the standard ECU. This is not so easy with the R33 ECU, if fact I reckon it is so time consuming (costly) that it is cheaper to buy a PFC. :)

Or just use the R32 ECU in the R33 - my old Mines ECU did the rounds of Perth including an R33.

The ECU is acutally a lesser known jap brand and i cant find any info on it at all.

Its a Power Selection ECU???

I assume that is is not tunable so I will probably look at a PFC, but considering I am about to fork out for turbs I may pospone the PFC until the cash flow improves! Hence my question regarding whether the N1s will be ok with the ECU thats in the car at the moment.

The car is an R33 GTS-T with an RB26DETT transplant, Im not sure whether it is an R32 or an R33 engine??

Thanks for the responses guys.

You are probably right - my old Mines ECU had a big dob of epoxy resin over the eeprom chip. Other brands probably follow suit.

As Steve-SST says above, I am selling my GTR PFC/HC/Boost Kit at a very cheap price in order to help pay for my rebuild. PM me if you are interested.

      R32 gtst speedo out by 10kph

      By GTSBoy · Posted

      Nope. The seal is in the drive. A new cable would just fill up and continue to convey oil to the speedo head. To check if this is what is happening, take the cluster out, dismantle the speedo and have a look. You probably don't even have to dismantle it. If there is oil coming up the cable, the drive into the speedo will be grossly greasy. I had to manually (and delicately) clean the gunk out of my speedo.

      Thanks for the quick response mate, and I agree Nismo 555s, Z32 and high flow 2871 in OP6 housing (run by PowerFC) would all be "period correct" and should be a simple, reliable and reasonably quick track car.

      It is normal for a speedo to read 0-10% high (unfortunately), intended by manufacturers and ADRs (although not in this case) to ensure your speedo does not read low if your tyres are worn. Speaking of which, what size tyres do you have on the rear, and what does they tyre placard say you should have? you can use this https://tiresize.com/calculator/ to determine what % difference that is causing Personally, when I buy tyres for a car I buy a size that will bring the speedo back to being more accurate; it if it reads 5% high I buy tyres that are 5% larger diameter. If you had an electronic speed sender like R33 onwards, the other option is to add a speedo adjuster but that won't work in R32. Finally, you  might be able to find a different sized gear for the speedo sender but that will be limited to what already exists (and I don't know what sizes do)

      OK...so dumb question to check....do the hi beams actually come on when the push the stalk to engage them (keeping in mind your headlight switch must be at ON as well)
