Paul Whiffin Posted January 9, 2010 Share Posted January 9, 2010 Sorry to hear that Lee, you seem to have nothing but grief! That gasket will definately be the reason why your blades are damaged. Although like everyone else says, the Precision 4088 turbos are known for there exhaust housing weakness. Borg Warner wise, I will be keeping these in stock very soon, I've got 3 turbos coming in from the US next week. 1 of them is my own car actually, Bullseye Borg Warner S368 with race cover turbo which is basically an S300 with S400 parts, cant wait to try it out. I dont think you can beat these turbos for price, reliability and availability, oh and they seem to work rather well to. Quote Link to comment Share on other sites More sharing options...

Tricky is saying it is the GARRETT housing that is flawed Paul, I have always used Precision Turbos that are basically hybrid garrett units and have never had a problem at over 2.5 bar, I have also heard that it is the Garrett that has the problem which is why the Boostlogic cars run units altered by precision.

Yes! have a word with Chris Wilson, at the time of the multiple failures (except for a a couple of R,s, don't know about them) Chris had several conversations with either Garrett or another turbo specialist and got the same answer from them, i also talked to Turbo Technics and was given the same explanation.

dude Posted January 9, 2010 Share Posted January 9, 2010 We are thinking about getting a spare turbo for my car, it will prob be a large frame ie T6 flange 4" Exhaust outlet, we will prob try a new company called Billet to see how god they are, they look pretty impressive to me.

Yep, AET Turbos modify the Garrett housings to stop it happening, they did this to the unit on my car and a few others we're running, no problems so far.

What is it that fails on the housing then Paul??? For the money Garrett want I would expect them to last a bit better. Quote Link to comment Share on other sites More sharing options...

L33 Posted January 9, 2010 Author Share Posted January 9, 2010 cheers for all the comments, looks like i should avoid the 4088 rather than fix. The S300sx 91/79 looks like a good option,and can make 600bhp is what i was after. just hope its not to expensive to buy.... Quote Link to comment Share on other sites More sharing options...
Luxluc Posted January 9, 2010 Share Posted January 9, 2010 I am looking closely at the BW S300 series too. The results on US forum look pretty good ... very nice torque at low revs, which is ideal for a road car. Quote Link to comment Share on other sites More sharing options...
Steve Posted January 9, 2010 Share Posted January 9, 2010 I have gone for the BW Airwerks 88/75 with a 1.0 a/r housing, it should be all up and working very shortly. Quote Link to comment Share on other sites More sharing options...
Luxluc Posted January 9, 2010 Share Posted January 9, 2010 I have gone for the BW Airwerks 88/75 with a 1.0 a/r housing, it should be all up and working very shortly. What bhp are you looking for (and @ what boost)? Quote Link to comment Share on other sites More sharing options...
Steve Posted January 9, 2010 Share Posted January 9, 2010 Trust me dude something has been thru that, a piece of carbon or exhaust paste or something, 100% Wish I could confirm for definite what it was mate. Either way the block/head have been fully rebuilt now anyway Quote Link to comment Share on other sites More sharing options...
Steve Posted January 9, 2010 Share Posted January 9, 2010 What bhp are you looking for (and @ what boost)? I spoke to Geoff at Full Race about this in a few emails. He reckons it should spool quicker than the old T67Dbb and produce more top end aswell. So anything around 650bhp is fine with me. I guess it will run around 1.7bar, but will see what we can get to on the dyno on super unleaded. Quote Link to comment Share on other sites More sharing options...
JamieP Posted January 9, 2010 Share Posted January 9, 2010 The BW does look a good unit, compare my billet T67 to ryans BW and they are very similar till the extra boost i run overtakes his, looking forward to seeing what Smarty's car (and ryans when he ups the boost) is like when fully mapped, might try one out myself.

Luxluc Posted January 9, 2010 Share Posted January 9, 2010 Wish I could confirm for definite what it was mate. Either way the block/head have been fully rebuilt now anyway I am looking at 620-650 bhp ... not sure whether 88-75 or 91-79 ... Quote Link to comment Share on other sites More sharing options...
Paul Whiffin Posted January 9, 2010 Share Posted January 9, 2010 What is it that fails on the housing then Paul??? For the money Garrett want I would expect them to last a bit better. Cant remember exactly but it was something to with machining the housings out for more clearance I think, they aren't designed to take the heat they are put through in the aftermarket world so tend to warp. Your right though, you pay that money you expect the best. Quote Link to comment Share on other sites More sharing options...

Paul Whiffin Posted January 9, 2010 Share Posted January 9, 2010 I am looking at 620-650 bhp ... not sure whether 88-75 or 91-79 ... 91-79 I reckon matey. I've got an 88-75 and 91-79 coming next week that I'll be trying out on a car with stock cams, both will be run up to around 1.7 bar, both will be dyno'd as well so should be interesting to see what they put out. I'll also be comparing it with a PT67 billet 0.68 non BB to see what the differences are. Quote Link to comment Share on other sites More sharing options...
L33 Posted January 9, 2010 Author Share Posted January 9, 2010 Well my target with the 4088 was 600 bhp so any thing about that will be perfect. With 650 injectors, 264 cams and was 1.5 bar of boost... Quote Link to comment Share on other sites More sharing options...

Don't you think 650cc will be limit for 600 bhp? Quote Link to comment Share on other sites More sharing options...
Kev.O Posted January 9, 2010 Share Posted January 9, 2010 I wouldn't rule the 88/75 out Lee. Only thing that's not in your favour is the manifold you have. Steve and myself use a twin scroll one. Geoff recommends the twin scroll set up Quote Link to comment Share on other sites More sharing options...

Id go for S300SX 88/75 on a 1.00ar, they compare it to the 4088 in this link. http://www.full-race.com/catalog/product_info.php?cPath=214_1167&products_id=1907&osCsid=bb12d43fe7d0aa4d7c1dda9687e2f2bb EDIT.

Geoff recommends the twin scroll set up Ahh, if you are on a undivided manifold then go with and undivided turbo, i would email Geoff for advice.
