Turbo conversion

[Col-GTSX]

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....

Its a VG30 standard unit, power would be 170 to 200kw absolute max. the thickness of the intake compressor wall is also standard.

VG30 specs

compressor 46mm top(RB25-48mm), 62mm bottom

turbine 48mm(ceramic)

I help him pull it off an RB25det motor....

Also the numbers were confirmed by Nissan

It is an R33 gts-t turbo (standard) with a tommy "race gate"

[BOOSTD]

looks identical to the turbo I pulled of my car on friday, has the groove down near the compressor to.(supposed to improve flow) 45v1 is the part number for the VG30 and R34 compressor cover. Also looks slightly machined aswell. how does a tommy race gate differ to standard?

[Cool Hand Luke]

is this a standard R33 RB25 turbo apart from the wastegate, or is it a rb25 turbo with a vg30 exhaust housing/wheel & wastegate? Or something totally different .

I posted the pics to see what you guys thought...

Im pretty sure now that it is a standard RB25det turbo with a tommy "race gate". However it does look like it has had a little machining... ????

Do you have any more pics of the turbo?

[Col-GTSX]
