Ok everyone has be telling me for ages that my turbo can't be stock for the power it makes.

I just recently heard some strange noises from the turbo area and decided to pull it off. The rear housing is standard as is the turbine(48mm ceramic). The compressor is 49.5mm top and 64mm lower. I compared it to a VG30bb and the trim on the blades is also different. The compressor cover is also a 45V2 VG30bb unit with slight machining.

Can anyone tell me if the 45V4 rb25 compressor is the same dimentions as the Vg30 or More like mine???? meggala???

Would be good to work out if it has been modified, seems to work very well. If it does turn out to be non standard, I would think a VG30 comp cover and high flow wheel with the same trim would be a very cheap upgrade.

full boost by 2500 to 3000

218rwkw @1bar

225rwkw @1.1bar

I am having it rebuild with a larger VG30 exhaust housing. I will post the result next week after it's finished and dyno'd.

the car came over with a chipped computer and massive fuel filter-go figure. maybe it had a package deal done, I have seen the advertised by tuning shops in japan.

Boosted,

What other mods have you done my goal is around 230Kw at the wheels dont wanna go too far past this as i still want a daily driver and something reliable...

Just wanna know what i need to get it to that kinda power.. slowlu buiding up.. i'll prolly get there in about 10 years though.

paydro,

the kit cost me $400 out of the local trading post. Normally around $1400.

The car will run a high 12 without the Nitrous. Tyres permitting a low 12 with the switch flicked. after I set it up on 50hp a 100hp jet goes in and 11's are on.

sounds very cool to me.

im in the process of upgrading my standard r33 for 12 sec passes but i dont want to use nos yet i want to keep the internals stock as well but planning on using a apexi power fc and avcr boost controller with an obvious turbo upgrade or larger internals.

theres a few other things ive got inmind but ill se how this goes first.

but nos definatley sounds like fun.

p.s. good pick up on the nos

drivebai, performance wise the car has a zaust, filter, cat in pipe, HKS EVC, Power FC, Cold air intake, Greddy front mount intercooler, oil/air seperator, octane booster for 12sec run and a HKS solid centre twin plate clutch. Also running 255 17" on the back.

Boostd thanks man.. i have all those mods except for about 90% of them hehehe so it looks like i will need Power FC, front mount oil/air separator, and hi flow turbo.. basically i need all the expensive stuff... yeah i got 255 17" on the back as well man... I wish you were in Sydney dude.. cos you are pretty much where i am aiming for round 230rwkw... would have been good if you could have taken me for a spin in your car.. so i can see what 230rwkw feels like and compare the differences between my fairly stock crappy car!!!. then i would have more incentive to save.. hehehe.

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.
    • My Nismo 1.5 churps a bit on reverse turns when cold, but besides that feels like a stock diff.
    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts
    • Bunnings would have just handed you your money back on that one!
    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
