Guest The Boz Posted March 1, 2010 Share Posted March 1, 2010 Hi, I just want to get a few opinions on what I'm thinking of doing. I'm looking at buying a completely stock supra tt and doing the bpu upgrade. I'd be looking at the whole works: upgrading the downpipe, cat-back, high flow cat or possibly decat, boost controller, boost gauge, fuel cut defender, turbo timer, and a remap. My question is this: due to my budget at the moment I'm looking at pretty high mileage cars, around the 80-90,000 mile mark, and I'm wondering if I'm asking for trouble pushing a car with these miles on it up around 400bhp? Thanks, Leon Quote Link to comment Share on other sites More sharing options...
Steve Posted March 1, 2010 Share Posted March 1, 2010 Thats not high mileage, thats just run in Quote Link to comment Share on other sites More sharing options...
Jamesy Posted March 1, 2010 Share Posted March 1, 2010 Yep. As above!!! Quote Link to comment Share on other sites More sharing options...
ilicos Posted March 1, 2010 Share Posted March 1, 2010 80,000 on a Supe is barely out of the factory! These are real cars! Quote Link to comment Share on other sites More sharing options...
Nic Posted March 1, 2010 Share Posted March 1, 2010 and a remap. The stock ECU cannot be remapped, you would need a piggyback or standalone ECU. Check the condition of the Intercooler, if it is the original factory fitted side mounted intercooler, it could be in poor condition. BPU puts more strain on the turbos, they may last a long time they may not, just something to be aware of. Quote Link to comment Share on other sites More sharing options...
Guest The Boz Posted March 1, 2010 Share Posted March 1, 2010 Thats not high mileage, thats just run in Ha ha ha brilliant. These are exactly the responses I was looking for. Nic, when you say check the condition of the intercooler, what exactly am i looking for? What are the tell-tale signs of a knackered one? Also, I'm aware that bpu will put more strain on the turbos, so I'm trying to find a uk spec one as I believe their turbos have steel impellors as opposed to ceramic ones in the j specs. Though I've only read this online and it could be nonsense. It does seem a bit illogical that toyota would only put these 'stronger' turbos on such a small percentage of the total number of supras they made. I wouldn't be going silly like 1.4-1.5 Bar anyway, more like 1.20-1.25, but I'd like that bit of reassurance either way. Thanks for the replies fellas, just the answers I needed.

leelbuk Posted March 1, 2010 Share Posted March 1, 2010 Nic, when you say check the condition of the intercooler, what exactly am i looking for? What are the tell-tale signs of a knackered one? You look at it starts to fall apart. Seriously though you'll know because it will have loads of the metal fins missing or when you touch any of the fins they will simply disintigrate and flake apart!

Nic Posted March 1, 2010 Share Posted March 1, 2010 (edited) Check the condition of the fins on the intercooler, if they are corroded, missing or break away at the touch then it'll need replacing. The UK spec did have steel turbos. There were very few UK specs sold though, so they are very rare. The UK spec turbos seem to suffer more with worn oil seals than j-spec turbos, they are also slightly laggier compared to the lighter weight ceramic j-spec turbos. 1.2bar is about the limit of both turbo, anymore and they just generate more heat for little power gain.

Dnk Posted March 1, 2010 Share Posted March 1, 2010 (edited) If its been looked after then 90k isnt high miles on a mkiv tt, mines done 128000 miles and been over 400 hp for half of them and is still going strong, its also on its original turbo's If the car you buy is an early tt and has its stock intercooler then it'll be scap and need replacing. It might need a new rad in it and an ac rad as well. Actually the list on o/e bits it might need is quite extensive and not just limited to if it'll cope with going bpu.

Guest The Boz Posted March 1, 2010 Share Posted March 1, 2010 Yeah I know about the rareness of the uk specs, i think they were only made from 93-96, also making them comparatively older. From what's been said I think I'll ditch the uk spec search and just get myself a j spec. Thanks again, Leon Quote Link to comment Share on other sites More sharing options...

The type of driving in HK though is very stop start so parts such as turbos get a good old work out. Quote Link to comment Share on other sites More sharing options...
Abz Posted March 1, 2010 Share Posted March 1, 2010 Great advise from members above, although worth noting I think Tiggers car had over 200,000 on the clock? These are real cars & 100k mileage if looked after well should be nothing to worry about. Few people could tell my car has done 105k!

tooquicktostop Posted March 1, 2010 Share Posted March 1, 2010 I always love the comments on mileage from members on here, 90,000 miles is ok ONLY if the car has been well looked after, serviced on a regular basis including the Major service items with correct fluids and has not been ragged within an inch of its life I would get the BPU done AFTER a full service and health check by a garage who know Supras BPU is a fantastic mod but can be very expensive if you push a tired car too hard Quote Link to comment Share on other sites More sharing options...
Guest The Boz Posted March 1, 2010 Share Posted March 1, 2010 Yeah a full service at a specialist when I first get one would be standard procedure anyway, whether I bpu it or not. My main concern, and I suppose what I'm really getting at by this thread, is whether or not bpu'ing a car at 80 or 90k is a stupid idea. The general consensus seems to be that it will be fine given that the car has been, and will continue to be, well looked after. Thanks again for all the advice, Leon Quote Link to comment Share on other sites More sharing options...
