i went from BPU to a T61 and the performance hike is MASSIVE the only thing i miss about the jap spec twins was the instant spool up/response, my T61 is making boost at 2700-2800 as opposed to the twins making it at a ridiculous 1800 so there is a bit of lag but not much, i know Vortex do a cracking kit for £1800 but realistically you can double this with fuel/ignition control and brakes and suspension (you will need this with even a small T61) if you have'nt got it allready and you will need a good intercooler (either stock or aftermarket) to make the most of the single, on the upside the performance with a single is in another league and if you EVER get blown off again it will be by something special or a supra running a T67 lol

Hi Keef, yeah shes still running on the safc, i had it set up by Thor who i would highly recomend it cost £150 and took about an hour to do with the ITC and a bit of adjustment to the FSE, the SAFC is defo a compromise solution you would get better afr's at the stock turbo change over point with an e-mange but as with everything in life you pays your money etc, it is do-able on an SAFC and the main thing is the fueling can be made safe, do a search you may find a "discussion" i had with Ian C :respekt: after a bottle of red (i did apologise) and you'll get the gist of the pro's and cons, if i was doing it all again i think i would get one of those cast manifolds Arnout does they look the dogs and a good price to

to be honest I didn't ask as it was a first run thing and not the final numbers. But i think it was something to do with the WG not actually doing it's job and venting so everythign went sky high ???

 

I just drive the thing and grin ;)
