coza Posted June 23, 2013 Share Posted June 23, 2013 hi I have a 1994 TT 5 speed I have just gone BPU , what's the next steps I've been told to get a boost controller but what needs doing after that ? Ideally I would like 450 - 500 bhp but what's the best way to get that ? Cheers Link to comment Share on other sites More sharing options...
Abz Posted June 23, 2013 Share Posted June 23, 2013 Best way is to search and read up on how to get to that... Are you sticking with the 5 speed with that power level? Link to comment Share on other sites More sharing options...
thetrashcanman Posted June 23, 2013 Share Posted June 23, 2013 You better look into changing the gearbox before you do anything else Options are Auto box from a TT good for around 550-600bhp R154 5 speed from mk III supra, should easily be able to handle 600bhp to my knowledge Or V160/V161 tractor box, good for 1500bhp As for achieving your 500bhp goal if you want the top end of that you would need some UK twins that are hybrids, or a small single, other than that you could probably reach the lower goal on J-Spec hybrids. About £1200 or so to get the turbos re built as hybrids from CR turbos I believe. Link to comment Share on other sites More sharing options...
coza Posted June 23, 2013 Author Share Posted June 23, 2013 No I will be changing to the 6 speed , so just uk spec turbos will be good for that ? , Link to comment Share on other sites More sharing options...
shaky Posted June 23, 2013 Share Posted June 23, 2013 You will need a new ecu,550's and a few other bits n bobs,i think a lad on here has done it with his dads car? . Link to comment Share on other sites More sharing options...
thetrashcanman Posted June 23, 2013 Share Posted June 23, 2013 (edited) No I will be changing to the 6 speed , so just uk spec turbos will be good for that ? , You might be better with a small single if you want to hit 500bhp, as you'll need a UK ECU, or something like a Syvecs, bigger injectors, larger intercooler Even if you got some UK twins with the right manifold you'd need to pay £1200 on hybrid one said turbos Edited June 23, 2013 by thetrashcanman (see edit history) Link to comment Share on other sites More sharing options...
Guigsy Posted June 23, 2013 Share Posted June 23, 2013 (edited) My uk car never got much over 400bhp. 500 is a long way off. And you never see a bpu hybrid turbo car that much over 450 unless your in the USA. And don't bother with uk turbos. They are actualy smaller than jspecs so they don't get the hybrid treatment. Even my small single gt35r (you dont go any smaller) makes 520bhp Edited June 23, 2013 by Guigsy (see edit history) Link to comment Share on other sites More sharing options...

Nic Posted June 24, 2013 Share Posted June 24, 2013 (edited) hi I have a 1994 TT 5 speed I have just gone BPU , what's the next steps I've been told to get a boost controller but what needs doing after that ? Ideally I would like 450 - 500 bhp but what's the best way to get that ? A top of the range electronic boost controller will spool up the turbos quicker by better controlling the wastegate and help to maximise the boost pressure through all gears. After doing the BPU modifications it starts to get very expensive, 430hp is about the maximum you can get from the stock j-spec turbos, along with high lift/longer duration cams, bigger injectors and mapped ECU. Fitting UK turbos is not that straight forward and would be a backward step IMO - they spool up slower and seem more susceptible to seal/bearing wear - I'd also not bother with hybrid turbos for the same reason.

coza Posted June 24, 2013 Author Share Posted June 24, 2013 Okay so really my next step is boost controller then change the ecu and remap ,, Link to comment Share on other sites More sharing options...
marc_p Posted June 24, 2013 Share Posted June 24, 2013 then change the ecu and remap ,, Not much point if you're staying with the standard TT setup, you'll be spending £1500-£2000 on an ECU that you might be lucky to squeeze another 10BHP from a better map. If I were you, I'd leave it as it is or go single. Link to comment Share on other sites More sharing options...

If I were you, I'd leave it as it is or go single. A new ecu will cost you so much for such little gain. If your lucky you may be able to find a mines ecu which can raise your rev limit slightly, and i think has a built in fuel cut defender ( I think) so dont quote me on it, And a slightly better built in map over the standard ecu setup. I have one in mine and thy come pretty well rated, If I pull my finger out with my single build mine will be up for sale But we'll see.

downimpact Posted June 25, 2013 Share Posted June 25, 2013 Question I've been wondering does a boost controller shorten the life of the turbos, assuming you only increase it 1.2 bar (perceived as the safe max)? Not in general terms that more boost will shorten life etc, but specifically does using a boost controller cause extra wear? Link to comment Share on other sites More sharing options...

Not in general terms that more boost will shorten life etc, but specifically does using a boost controller cause extra wear? I am no expert on this, but shall answer as best I can. Tbh from what I've seen increasing the boost on these car's that are most getting on for 20 year's old now, doesn't seem to affect them to badly, damage to the turbo's etc, But in theory it will shorten the life of the stock turbo's as they where really designed to spend most of there life running at 0.8 bar.
