Subject: Ford Sierra 2.8 Turbo Technics
Sender's Name: Christopher Walley
Question: I've had your email address passed onto me from a Sierra Xr4x4 owner who said you might be able to help. I own a Turbo Technics Mk1 Sierra 2.8 v6 and I'm trying to source some low compression heads for it, can you help?
Answer: Yes, I can help with the heads. If you have a good pair of standard heads, we can get them modified for you. They cost from ?300 to ?600 plus vat, depending on the specification.

Question: Ive got a vauxhall calibra 4x4 turbo when i try to accelerate it splutters if I boot it. I have just bought it and it sounds mechanically sound apart from it sort of chocking up and misfiring. I've checked and changed the plugs and they look fine they are a lovely shade of grey and not wet at all - please can u help me
Answer: I can't see any alternative to taking to a specialist - these are so complex. You need to have a code read done, to check the management system. You could check for air leaks from the pressure hoses, and the intake pipe to the air flow sensor.

Question: I own a '93 Clio 16V with fsh, in good nick etc. Mods I have to date are K&N, Scorpian exhaust, Superchip. I have been told that if I get the Head gas-flowed this will give vast improvements in performance & complement my existing mods. Please advise approx cost for this & also how long it would take.
Answer: Vast ?...I doubt that to be honest. The best figure I heard of (and believed )..was 20 bhp extra, that was from a ?600 cyl head, and at 6000 rpm. Try Prima Racing, and be prepared to subtract 20 % from the figure they give you.

Question: I HAVE A VAUXHALL CARLTON 1.8I AND HAVE RECENTLY REPLACED THE BIG END SHELLS IN IT. THE ENGINE IS BACK IN THE CAR NOW BUT WHEN I START IT UP IT TICKS OVER VERY FAST,WHAT COULD BE THE PROBLEM OR PROBLEMS.
Answer: Check for sticky throttle, or stuck idle valve. Don't try to adjust the idle in any way, as you can't do it. Also check for air leaks.
