Jim_1979 Posted April 6, 2008 Share Posted April 6, 2008 My car is a BPU Jap TT. It's been fitted with UK turbos. Curious if there are any advantages of having the UK ones? Link to comment Share on other sites More sharing options...
Nic Posted April 6, 2008 Share Posted April 6, 2008 No not really any advantage, they are smaller and spool slower. Link to comment Share on other sites More sharing options...
dannysupratt Posted April 6, 2008 Share Posted April 6, 2008 No not really any advantage, they are smaller and spool slower. DAm i thought they were better:tongue: cant they handle that extra bit of boost though, correct me if im wrong. Link to comment Share on other sites More sharing options...
Jim_1979 Posted April 6, 2008 Author Share Posted April 6, 2008 Are they not steel instead of ceramic or something? Link to comment Share on other sites More sharing options...

jazz1 Posted April 6, 2008 Share Posted April 6, 2008 so are uks slower? Link to comment Share on other sites More sharing options...
Nic Posted April 6, 2008 Share Posted April 6, 2008 DAm i thought they were better:tongue: cant they handle that extra bit of boost though, correct me if im wrong. They can handle around the same boost as the J-spec turbos; ie. circa 1.2bar. Link to comment Share on other sites More sharing options...
Jim_1979 Posted April 6, 2008 Author Share Posted April 6, 2008 Can they not handle more boost pressure then, seeing as they're steel? UK's are usually more bhp out the box compared with Jap TT's are they not? Link to comment Share on other sites More sharing options...
Nic Posted April 6, 2008 Share Posted April 6, 2008 Are they not steel instead of ceramic or something? Yes they are steel internals which is why they spool up slower. Link to comment Share on other sites More sharing options...

Jim_1979 Posted April 6, 2008 Author Share Posted April 6, 2008 Yes they are steel internals which is why they spool up slower. For the same reason, shouldn't they be able to handle more boost? Link to comment Share on other sites More sharing options...
dannysupratt Posted April 6, 2008 Share Posted April 6, 2008 Can they not handle more boost pressure then, seeing as they're steel? UK's are usually more bhp out the box compared with Jap TT's are they not? yeah supposedly 326 too 280 but its not true, my j spec was 310 standard and that was 10 years old. Im sure my uk is quicker with the bpu though Link to comment Share on other sites More sharing options...

The J-spec and UK spec Supra are both around 320hp as standard. Over 1.2bar and they will generate more heat and no extra hp. Link to comment Share on other sites More sharing options...

AgtX80 Posted April 6, 2008 Share Posted April 6, 2008 Most of the time with cars in general, the jap models are faster than the UK ones cause the ecu is set up for the better petrol in japan among other things. Link to comment Share on other sites More sharing options...

Nic Posted April 6, 2008 Share Posted April 6, 2008 i thought jap tt bpu was about 400bhp and uk bpu was 420bhp No the absolute max possible for both is around 430hp Link to comment Share on other sites More sharing options...
dannysupratt Posted April 6, 2008 Share Posted April 6, 2008 No. o ok maybe not lol, so are uk bpu supras not any more powerfull at bpu Link to comment Share on other sites More sharing options...
Gazboy Posted April 6, 2008 Share Posted April 6, 2008 If you look at the drag times sticky you'll see that UK or Jap is irrelevent to times. Link to comment Share on other sites More sharing options...
Nic Posted April 6, 2008 Share Posted April 6, 2008 o ok maybe not lol, so are uk bpu supras not any more powerfull at bpu No pretty much the same. Link to comment Share on other sites More sharing options...
Suprash Posted April 6, 2008 Share Posted April 6, 2008 No pretty much the same. So what advantage do they have by fitting steel blades to Hybrids Nic, or is it that they cant get ceramic ones to fit as surely ceramic being faster spooling would be better. And from the early days of being on the bored, UK's where always regarded as slightly more powerfull but as I understand on Hybrids the housing is often bored out slightly no......
