mr keef Posted January 3, 2008 Share Posted January 3, 2008 I know theres lots of opinions about the best turbo..power...spool...BHP...etc etc etc,but whats the best all round turbo?something that spools fast,low lag,good power,doesnt run out of puff at the higher revs...is there a turbo out there that people agree is a fantastic turbo that meets all demands?i had the T51R loved it on boost..but didnt come online till 4k but once online was mental is there something that comes online say 2k with great spool and power? have your say..

Wez Posted January 3, 2008 Share Posted January 3, 2008 Small to large I would say 60-1, T61, GT35R and GT4088R My 60-1 is producing 554hp and there may be a little more in it yet, Ryans T61 is running approx 560hp, I am not 100% sure on the other two.

JamieP Posted January 4, 2008 Share Posted January 4, 2008 Go small, for fun on the rd 500/550bhp and fast spool is great fun and all that is needed imo, I went from a laggy 670bhp to a fast spooling 550bhp and i can honestly say the smaller turbo less powerfull car was faster in 90% of conditions and far nicer to drive. If i get another supe im gonna try a journal bearing GT35. Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted January 4, 2008 Share Posted January 4, 2008 If i was going to Single turbo another Supra in the future i would like to try a T67 DBB on a custom cast manifold. As the T61 and T67DBB seem to be close in the midrange on SS manifolds. Smaller Single turbo's like the t60-1, t61 and gt35 that i have mapped always have issues with traction in the first 3 gears at full boost which IMO can be annoying when getting off the line. But easily solved with a Speed Dependant Boost setup and R888's Then they are just incredible! Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted January 4, 2008 Share Posted January 4, 2008 I have owned a few single turbo cars and run several set ups including T88's T78's, T04R's and T04Z's and the smaller turbos are great fun on the road, the T04Z was perhaps the best for me as it spooled quite quickly but had big BHP potential, I think the only problem with going too small is they are great fun but you may get a little bored and be looking for more power after time, I would say a medium size turbo is the best for a street car Quote Link to comment Share on other sites More sharing options...
Nic Posted January 4, 2008 Share Posted January 4, 2008 I run a GT35R AR 0.82 with T4 housing, low down response is similar to a BPU TT, mid to upper rpms there is a lot more power and it pulls very strongly to the rev limiter (HKS i256/e264 cams also fitted).

tooquicktostop Posted January 4, 2008 Share Posted January 4, 2008 There is a T67 on the graph with 256/264 not sure if it as DBB, I an going for 272/272 cams with the T04R in the new build, will be interested if this gets me through the 600 mark as it made 580 with the 264 ex and stock inlet cam Quote Link to comment Share on other sites More sharing options...

tooquicktostop Posted January 4, 2008 Share Posted January 4, 2008 Out of intrest Dean are you staying with the AEM and who will be mapping it? I plan to stay with the AEM yes, I have purchased an AEM dash mounted digital readout to tell me exactly what is happening with knock, O2 etc which is being fitted now, I have spoken to a few people about mapping including Ryan, will be very careful about this when the engine is run in Quote Link to comment Share on other sites More sharing options...

Alex Posted January 4, 2008 Share Posted January 4, 2008 That T67 is a journal bearing, NOT a DBB. I'd have a GT35R, GT4088R, T61 or T67DBB. Quote Link to comment Share on other sites More sharing options...

Ian C Posted January 4, 2008 Share Posted January 4, 2008 I thought Ian had a DBB Alex? The stock camm'ed T67 is DBB and it was Homers, mine is indeed a dark line buried in there somewhere and it's the 256in 264ex DBB T67. It's probably not at it's best due to a permanent boost leak in the wastegate area and my lack of ignition timing up top, which I know Ryan is aware of and keeps twisting my arm about Both will be sorted when the weather improves -Ian Quote Link to comment Share on other sites More sharing options...
magictorch Posted January 4, 2008 Share Posted January 4, 2008 I think Jamie had a T88 in the original set up and went on to a GT4088 I take it that the GT4088 was the better one? I only ask as thats whats waiting to go on mine:) Quote Link to comment Share on other sites More sharing options...
