You will know when you have ceramic GTR turbos when the car has good response and makes boost early, if the car is laggy and you're not making full boost till after 4000 you could do an educated guess that you have a pair of GTR turbos with steel wheels.

I don't have a higher res version of this unfortunately:

you should be able to see if you look carefully on the front turbo cartridge, ther should be a badge there with a bunch of numbers

post the numbers up, but if there stock turbos that have been rebuilt only way to tell is to pull them off

Stockers should be at a bar at more like 3000rpm - IF everything working properly. So either you dont have stockers or something is wrong with your car.

it made 260kw at a bar, decat, strait through zorst...

drives like a dream, everything seems normal and safe...

im going from an rb30et, ive got no idea about response

anyone in melbourne wanna drive it???? free meal on a rainy weekday night for someone who can tell.

it seems like its making a bit more power the stockers, i made 220 with the same mods as you back when my car was stock my motor was healthy aswell,

i was also getting 1 bar by 3000-3400rpm

but it could also be a high reading dyno

i would take you car for drive but its been that long since iv driven my car i dont know what the stock turbos feel like anymore

did you have look for the numbers??

i havnt as yet, have to poke around this weekend.

it made 257 on racepace dyno after the cam gears

and 248 on re customs 35 deg stinking summer afternoon

it from japland came with a half cage, 2 mad racing seats, good steering wheel with d1 hub.. boost controler etc... full colourchange respray?? its had track work in japan (translated paperwork), pervious owner took it to easternats, he said it has steelies in it <-- he told me it had alot of other parts that ended up to be true (clutch, suspension) etc

i cant see why anyone would mod like this and still have the bourden of it blowing up on their shoulders

i just wanna be sure.... :P cause in the end i dont know

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
