shervin_ice Posted November 19, 2019 Share Posted November 19, 2019 Hi , Is there any one can confirm that the bolt pattern are the same between jap spec and Uk spec turbos to manifold? ,I know that the turbo cartridge are different, I’m planning to rebuild my jap spec turbos so I have a spare Uk spec turbo without manifold , I just wanted to make sure the bolts pattern are the same or I should get the Uk spec manifold and etc Any help would be great Thanks Quote Link to comment Share on other sites More sharing options...
Frank Bullitt Posted November 19, 2019 Share Posted November 19, 2019 No bolt pattern is different between the UK and J-spec turbos. You need the full kit. Quote Link to comment Share on other sites More sharing options...

So you are saying I can bolt on the Uk spec turbos on my jap spec manifold? What kit do I need ? Quote Link to comment Share on other sites More sharing options...
Frank Bullitt Posted November 19, 2019 Share Posted November 19, 2019 The bolt pattern on the turbo where it bolts to the OEM manifold is different, to use UK specs turbos you will need a UK spec manifold. The turbo heat shield is different too. Quote Link to comment Share on other sites More sharing options...

Frank Bullitt Posted November 19, 2019 Share Posted November 19, 2019 No worries, I must ask, what are you planning to do? Hybrids? If that is the case, J-specs make better hybrids than UK specs. Quote Link to comment Share on other sites More sharing options...

Well I’m planning to rebuild my jap turbos and find some to rebuild them to hybrids but I thought I but the uk spec turbos on my car to use it but unfortunately I don’t have the full kit to do that , Is it worse to go hybrids or it’s just waste of money as I heard they don’t last that long Quote Link to comment Share on other sites More sharing options...
Frank Bullitt Posted November 19, 2019 Share Posted November 19, 2019 Is it worse to go hybrids or it’s just waste of money as I heard they don’t last that long. Do your OEM turbos need a rebuild? Why hybrids? Do you want more power? Are you currently running sequential or TTC? If running sequential, do you plan on running TTC in future?

shervin_ice Posted November 19, 2019 Author Share Posted November 19, 2019 My no2 turbo passing oil but boast fine and I’m not running TTC , But by doing hybrids I might change the injectors for bigger and running more power as I’m on Boi atm and had a quote £1400 for making them hybrids don’t really know if that’s the good way ?

Frank Bullitt Posted November 19, 2019 Share Posted November 19, 2019 (edited) Rebuilt OEM and hybrid can be reliable as long at they aren't subjected to abuse. Things like bouncing off the rev limiter, anti-lag and 2-step. Rebuilding using stock sizes would enable you to increase boost slightly so you would gain a little more power. Going hybrid, as in re-working the OEM turbo to take larger internals from the "disco potato" (2860) or 3071 will give you power but terrible lag and an awful drop in torque and power when turbo 2 two comes on line. Having looked at the various printouts it looks like a terrible conversion. If you want bang for buck and a quick spooling 500hp supra then a cast manifold and small single is the recipe. There was a similar conversation going on recently, this thread might give you a few options - http://www.mkivsupra.net/vbb/showthread.php?355254-Hybrid-highflow-twin-turbos-VS-small-single-turbo-setup Edited November 19, 2019 by Frank Bullitt Link added.

Swampy442 Posted November 19, 2019 Share Posted November 19, 2019 J spec turbo's - 3 bolt UK spec - 4 bolts. The manifold to head stud pattern is the same. Ive got a UK spec manifold if you need/want one Quote Link to comment Share on other sites More sharing options...
