tonyhawk Posted July 28, 2005 Share Posted July 28, 2005 I have recently had the turbos on my Mkiv ('93 jap spec TT) rebuilt using oversized steel rotors etc., reconned and balanced etc., and according to the shop, they should be good for 1.5bar. However, my car as it is may not, hence is the question: It's a Jap spec, original fuelling with the exception of a Walbro pump. The block and pistons have been done (JE). Head gasket is the HKS 2mm (ready for the big guy(s) when I can afford it). The head has been fettled and the cams are 264 in and out. HKS adjustable cam wheels I have IK24's in there. Boost is being controlled by an EVC V. The exhaust is HKS with the second cat removed. The rest of the turbo set up is stock. No intercooler yet Given the current state of tune, what pressure can I run? I realise the best bet would be to take it to Thor or wherever, which I will be doing in a few weeks when I will be treating it to a piggy back ECU and professional tuning hands, but it's currently running just under 1bar, and it seem wrong to waste the new toys for so long.. :thumbdown . However, at the same time I don't want to break it! Any help would be appreciated. Thanks Tony Link to comment Share on other sites More sharing options...
D3xt3r Posted July 28, 2005 Share Posted July 28, 2005 You wouldnt go higher if you dont have an Fuel Cut Defender. If you have I wouldnt go above 1.1-1.2 Bar till the fuelling is sorted. Link to comment Share on other sites More sharing options...
tonyhawk Posted July 28, 2005 Author Share Posted July 28, 2005 Cheers. Forgot to mention, I do have an FCD; I'll tune in 1.2 and see what happens. The biggest problem is power at the turn of a button...... I can resist anything but temptation.... Link to comment Share on other sites More sharing options...
