Turbo Rebuilders in Perth

[memphis]

Cam, I think it's possible to put a steel wheeled RX7 turbine in a machined RB25 turbo housing, might cost the same as a rebuild but provide a bit more power and reliability.

Im quite sure this is what I have, boosts up to 16psi easily, one day ill get around to the dyno.

I always use ATS in O'Connor

Cheap n Freindly service.

Rebuilt my VLT T3 with T4 internals as well as Hi Flowing......$1200

It has produced about 280rwHP @ 9psi on 9.0:1 comp RB30......I'm hoping it will be good enough to produce 400rwHp on 7.8:1 Bottom end I now have !....?

Anyways - on inspecting the compressor wheel on my old turbo vs my new one, I found that the new one has dual vanes while the old one has single? Any ideas? I'll post up comparative pics tonight.

Righto - Pic of the old vs new compressor wheels attached.. Any ideas?

[caminperth]

Hmm - fitting the turbo is turning into more than just a re-bolt on. Have found some problems as a direct result of bad workmanship by *** performance (in wangara - you work it out) who fitted the dump - missing bolts and flange holes not lining up by a mile. You wouldn't think the fabrication of a flange would be so hard...

Pic attached of the poor workmanship of the dump. Absolutely pathetic and I think people should know so they can be aware of the quality of work to expect out of some places. You could argue that it'll work - which it will - but you'd expect this sort of crappy workmanship out of a backyard mob - not from somewhere who suposedly specialises in "performance" work.

Pic of the old vs new exhaust wheel. Notice the difference?

old one go :Bang:

ah Cam nice sandals u have there

PM me the place that did the dump cheers mate

i know with the mitsi turbos the TD04 is single blade and the TD05 has the twn blade thingo like yours cam, not saying its mitsi, but maybe some sort of upgrade, which might explain rev's times??

[GOT BOOST]

i think the single blading would make more power

[caminperth]

Getting the stud out today so will bolt on tonight and give a 'seat of the pants' verdict.

GOT BOOST - What makes you say the single blade compressor would be better?

[GOT BOOST]

just from other turb's ive seen and had my cars before.

could be wrong but thats my 2 cents for what its worth.

[caminperth]

GOT BOOST - thoughts appreciated.

Have also posted in the forced induction area.. maybe someone has seen this style before...

Cam, I'll ask Grant tommorow, and post up what he says is the difference between the two styles of compressor wheel.

Might explain my times if this turbo was actually off my car. My turbo has twin blades tho' for the record.

[APA]

hmmmz, maybe this is the cause for rev's crazy times

[zanda]

I dont really think revs times are that crazy?

he had 170 hp, with a lightened flywheel and reasonably soft (deflated) rubber.

granted, it was on thin tyres, but Ive read of quite a few people getting those sorts of times with similar power.

[APA]

okay perhaps not crazy, but better then most, with less mods then most

I spoke to Grant at Per4manz, and he said that the twin blade design doesn't seem to impact on efficiency or power, but it does make the turbo noise quieter.

[zanda]

I personally think people underestimate the effectiveness of a lightened flywheel..

*thinks back to the nissan micra super turbo on GT2 and the difference it made when he lightened the fly*

granted, that was a puter sim, but a lightened fly would make a hell of a difference.

[fane]

mmm i look forward to the day i get a lightened fly...

[caminperth]

The twin blade is going well. Boosts better than the old one and seems to hold more boost on the same actuator. I think my old S2 single blader was fairly shagged out!
