Steve Posted October 24, 2009 Share Posted October 24, 2009 Maybe these .68 housings are just to small for the Supra engine? Quote Link to comment Share on other sites More sharing options...
Geo Posted October 24, 2009 Share Posted October 24, 2009 Im now worried mine will do this once its been mapped by Ryan. I thought precision were ment to be making some good turbo builds, by the looks of things they aint lasting that long.... Quote Link to comment Share on other sites More sharing options...
paul mac Posted October 24, 2009 Share Posted October 24, 2009 i have posted it before but it seems worthy of mention here, i contacted two very well known turbo re-builders in this country, one refused point blank to have anything to do with Precision turbos and the other was more forthcoming, they would not re-build Precision turbos due to the low quality (their words) of the turbo materials and construction, in the past they had many warranty claims on Precision units they re-built, so they took the decision to no longer re-build them Quote Link to comment Share on other sites More sharing options...

jevansio Posted October 24, 2009 Share Posted October 24, 2009 (edited) Garrett do a billet wheel (for their biggest turbos) but it doesn't offer any performance upgrade over the traditional cast wheel. The fact a wheel is billet makes no performance increase in itself, it's the fact the Precision billet wheel is a different design to the non-billet wheel See here http://www.turbobygarrett.com/turbobygarrett/news/race_updates/Garrett_Fully_Machined.html Edited October 24, 2009 by jevansio (see edit history) Quote Link to comment Share on other sites More sharing options...

jevansio Posted October 24, 2009 Share Posted October 24, 2009 So effectively anyone wanting these performance upgrades will have to buy a precision turbo TBH from what I have read there is little "performance" upgrade in billet vs cast in the Precision range until you start to run serious boost.

jevansio Posted October 24, 2009 Share Posted October 24, 2009 Funny how you dont read of these failures on supraforum.com. The amount of failures I've seen on here must be 10 - 20 times that I've seen on SF, come to think of it I can't recall a single instance on there!

jevansio Posted October 24, 2009 Share Posted October 24, 2009 Bugger. I've just sold my T61 and was looking at getting a billet precision turbo It's not to say that's a bad decision. it's hard to get solid facts but IIRC there was maybe 50-100 rpms spool difference (how scientifically that was measured I have no idea). I def wouldn't go into it with the mindset "I want a billet turbo" - just because it's billet. I wanted a T67 sized turbo & these were making good figures and I was planning on running as much boost as I could so figured there would be a small advantge in getting the best high boost T67 I could. Plus I am a sucker for having the "in" thing in turbos, take DBB, you pay extra for that & there is no way they are that much better than non-dbb.
