Question: Hi, my STi PPP has recently developed a hesitation only when accelerating gently between 1500-2000 rpm. Just seems to hang back. Been to main dealer for checks but no faults found. ECU cleared (now feels like a non PPP!) but hesitation remains. At some point I\'m planning to visit you for forged pistons but is this the prelude to the dreaded ringland failure?
Answer: Hi. That doesn't sound like a piston issue, but rather more like there's something the matter with it. If it were possible, I'd dyno test it and go from there.

Question: Hi, I have a 97 jap import impreza turbo with a small coolant leak coming from I believe near the rad, is it ok / safe to use radweld on these cars ?? Cheers lee
Answer: NO! the rads split, and no amount of redweld will protect your engine if it gets worse.

Question: Hi Alan I have a 98 STI, i shot a piston, got a re-con engine, but it never felt as smooth as before, i recently blew the head gasket.the engine is under waranty so i can get the work done, but what would u advise i do 2 make my car run smoothly? i kept gettin a fuel cut, which must have something 2 do with the fuel pressure regulator. i want 2 bring it 2 ur workshop but wana no wot u would do n how much it wud cost please. i fink rolling road wud be a must, at least, but i want it more responsive with costing me a bomb. cheers
Answer: Hi Jamie - If it's a version 4 we can't actually map it. If it's faulty we can fix it, it sounds like it may be overboosting. As soon as you get it back, book it in with us, and we'll check it out for you. We charge £70.50 inc vat for a dyno session which will tell us all we need to know.

Question: Is the price for the close deck engine built is £4150? If not then how much is it also the price for the 450bhp built.i have a standard turbo 280bhp max output which Im ok with for the moment but i wouldnt wana go over 500bhp in the future, so need an engine built to 550bhp max.
Answer: Closed deck blocks are costing £500 these days, plus vat. They also need the rear thrust machining to be done. I don't honestly think you need one with the turbo you are going to be using. £4150 covers a full drive in drive out 2.1 stroker engine build. Considering everything you've told me you don't need to spend that much on the car. you could just go for a 350bhp conversion, which still isn't exactly hanging about. Feel free to call me on 01752 345880 if you'd like to discuss it.
