Welcome,

 

Sounds like you have some big problems.

 

Its going to be an oil pump change at a minimum id say, when people just try and replace the seal it blows very quickly again, sometimes it seems to be a sign of a very worn engine.

 

What ecu do you have?

 

Good luck with anything xs power, i feel you are going to need it.

You are going to need to spend a fortune on that to get it running right and you will still be on a xspower kit, might be better to put it back to stock twins, or start over with the single conversion with a good quality kit, if i was you id never let that car come on boost till sorted.

Ouch. I don't think you are going to enjoy Supra ownership much mate. :(

 

When you say 'high boost' how high are we talking about? From what you've said above it sounds like your car still has the standard fuel injectors. Std injectors can barely enough for BPU let alone a single turbo at anythng even approaching high boost.

 

Was the car originally a TT or a NA?

 

You might well be better of junking most of the XS power stuff. Their turbos and manifolds are utter garbage. The intercoolers and exhausts are the only parts I would even consider using.

 

 

Best of luck dude.

Take it from someone who ran there stuff for a while, all being i had no problems(which i was real lucky with) i decided i wanted to do a better install. When the old stuff was taking off Ian who did my single build was shocked to see the state of the parts.

 

Id be saving my pennies up and changing all XS Power stuff for newer well made parts, money talks when doing a single build. Im glad i did change mine, as im sure the car would of went tits up when running the Xs power gear.

All the above is good advice and ill 2nd it all.

Going cheap on single turbo kits usualy ends badly and you end up with a large bill at the end.

 

To be fair though some people have ran OK for a fair while on xs stuff with good results but eventualy the cheapness will bite you in the arse

Id vote for the Whifbitz one for two reasons, 1 Cost as its cheaper than some of the kits from the states and 2 the parts are better quality.

 

The No1 selling factor for me besides my car being the guinea pig was the manifold has a 5 year garentee :)

 

:yeahthat: im running one on my single, and it does look the nuts. And works really well. :D

That's until you decide having 2 wastegates is better than 1 :p

 

Ill vouch for the whifbitz kit also, I've seen it in person MANY times now and the quality is supurb on all the pipework plus the fact its made over this side of the pond so no high cost import charges and huge waiting times
