I went down to an Import Wreaker the other day and was going to buy a VG30 to fit onto my RB20Det motor. However when i was there they were dismantling a tommy R33. So i looked at it and found it has a different turbo to the norm.... So i bought it along with the spagetti extractors and internal "tommy race gate". This turbo has been inspected by a turbo pro and it has the following;

1. Steel blades

2. BB

3. Different wastegate release valve

4. Twin blades

5. Bigger oil/water lines

6. Different out put pipe (as to a standard gts-t)

But the wierd thing is it is baged as a NISSAN turbo....

However it has a "tommy race gate"

Is it either someting very different

or

Is it just standard but with a different wastegate....

Photo is included bellow...

I am fitting it on Tuesday 24/6 so i will post how it works out.

The exhaust is has to be modified on the 25th so hopefully it will be back together that night... and driving....

Reason for conversion the T3/4 i have now is too large and has massive lag... I suggest to anyone who wants a T3/4 on an Rb20det think agian... I spent too much on mine and was dissapointed in is performance....

Anyways ill be selling it soon... Has only done 14,000k's

Will suit a VL perfectlly or RB25

Anyways i will post again on wednesday...

Cheers

Well guys... I have a smile from ear to ear

The turbo conversion is over. And boy does it go....

However im having trouble controlling the boost my bleed valve when screwedf all the way in is still producing 20+psi... (Cant tell cause my gadge only goes to 20psi...) Anyways ill sort that one tommorrow... So i drove it around tonight half pedal all the time...

She is spooling at like 2400rpm and hits like a car up the arse at 2900rpm then its hang on while the wheels find their step all the way to 8000rpm... I recon with out a doubt its over the 250rwkw by now.... I can believe it..... The tyres just fried when i smacked 3rd at 5000rpm with 14psi.... The spedo reads 140kpk however im doing about 40kph.... Its a weapon now... Will need to srt out the boost tommorrow...

Anyways it took about 6 hours go to whoa. The oil lines matched up perfectlly. However the water line inputs on the turbo from the R33 have a different thread. So we used the supplied R33 water lines... What a bastard to get that rear one.... HEHEHE

The exhaust was a different issue... But that will be corrected in the morning as well.... The intercooler piping needs a little attention as well, as they didnt match up due to the 2.5" output from the turbo going into 2" intercooler piping... So all in all a head scratcher but were there.... Plus i cought a WRX so im happy.... He smaked off the line 4x4 style and i passed him at 17psi through 2nd... One night of over boost wont hurt... HEHEHE

Anyway check out the 4 sale section for the parts i didnt use and the old parts im selling....

Sweet

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
