Steve Cargill Posted July 20, 2002 Share Posted July 20, 2002 Just curious, but can the UK turbos be used as a direct replacment for the J spec ones, or is there lots of other work involved? Also what difference would they make power wise? Quote Link to comment Share on other sites More sharing options...
Adam W Posted July 20, 2002 Share Posted July 20, 2002 They don't fit in any way shape or form from what I've heard. Get some hybrids! Quote Link to comment Share on other sites More sharing options...

Benefits....a bit more HP but less torque, more top end and more lag....waste of time really. Quote Link to comment Share on other sites More sharing options...
Steve Cargill Posted July 20, 2002 Author Share Posted July 20, 2002 Thats a no then Thought it probably would be. Thanks. Quote Link to comment Share on other sites More sharing options...

Also the J spec ijectors woulfd be OK as long as you didn't run too much boost. As long as you changed to the UK turbo manifold & Down pipe I can't see a problem. I assume te VSV's are the same. Having said all that, I can't see the advantage. If you hybrid the J spec they actually have a bigger compressor wheel already. Quote Link to comment Share on other sites More sharing options...

Apparently the fluttering noise I get on part throttle at 2.5>3k RPM means my turbos are on the way out and I'm looking at options so when they do go I know what to get - may even change before they go, it depends. If I also need a new manifold and a new de-cat pipe then it's probably not worth the hassel anyway. Quote Link to comment Share on other sites More sharing options...

I was under the impression that the impedence of the packs were different between models. I'm probably wrong, it has happened once before Quote Link to comment Share on other sites More sharing options...

Steve, I get a simelar noise from my hybrids, JB & Adam Wooten have both heard the noise too, I dont think it means the turbo is shot (well I hope not!). Its quite hard to describe the sound it makes, but maybe its just a wastegate problem. I've yet to get it back to Leon to take a look for me.

Guest Terry S Posted July 20, 2002 Share Posted July 20, 2002 Gavin the injectors are a different impedence but this needs a resistor pack & does not affect the coils. Steve, I believe I have seen you car at Leon's. By the time you have got the UK turbos , manifold & DP then you may as well get a set of his hybrids. Barry, yours should be pretty indestructible. I will be interested to hear what Leon says though. If your turbos were f*cked you'd know by now. Quote Link to comment Share on other sites More sharing options...

Steve Cargill Posted July 20, 2002 Author Share Posted July 20, 2002 Terry, that was my car at Leons - I think it was starting to become part of his garden but it's back now, still a few things to do to it, but at least it's back on the road now :D After I got it back I noticed the noise and when it went back for it's check up I took him out and let him hear it and that was his diagnosis - it also seems a little bit down on power (less aggresive that it was) on the first turbo. The noise is only noticable at about 1/2 throttle when the car is pulling (auto) and about 8-10lbs boost. You can only hear it with the windows up. Hard to describe it, but it pulses about 3 times a second - fluttering steam train maybe.... I may have been able to get a good deal on a pair of UK turbos, but as you say with all the other changes hybrids are the way to go. Quote Link to comment Share on other sites More sharing options...
