Question: Hi, Can you tell me the torque settings for tightning down the head on a Renault Clio 1994 1200cc. Thanks
Answer: 20 nm then 100 degrees plus or minus 6 degrees Wait 3 minutes, then slacken the two middle bolts Retighten to 20 nm then 100 degrees plus or minus 6 degrees Then slacken the four inner bolts and re-tighten to 20 nm then 100 degrees plus or minus 6 degrees Then slacken the four outer bolts, then re-tighten to 20 nm then 100 degrees plus or minus 6 degrees And some people wonder why we charge what we do!

Question: Calibra 16v- I have a slight misfire on engine at low or high revs.Changed leads,spark plugs,even dizzy pack no joy,not even engine management light please help.
Answer: Have you done a compression test? It doesn't sound like an air leak, as the misfire would normally get better with revs. Possible injector problem of course. Plugging a diagnostic device in might show something up, most of them have live data to get at.

Question: I have put a pierburg 2e carb on to two different cars on two seperate occasions but what I am getting is neither of them are ticking over. I am wondering if it is to do with the jets that are in there. do you think that you could tell me if im right and what size jets I should be using. there are three in total. thank-you. sorry about that my engine size is 1.2 and it has a carb on it already. Cheers.
Answer: Memory fails me here, but if there is an idle shut off solenoid on that one, it may be failing to idle due to the lack of ignition feed. Apart from that, it may just be blocked jets. The idle jets are small, and clog up easily. In truth, it's the sort of thing a decent tuner could deal with very easily.

Question: Hi I have heard that u can de-restrict the air box in total Vauxhall but how? If not will a universal induction? and if I change the back box to a Peco power master and take the middle box out but leave the cat in will I gain anything? o yer and do u no anything about ecotek cb-26p valve?
Answer: Hi.. Most airboxes can be modified by simply drilling holes in the lower section, preferably at the front end, where they may pick up some more cold air. They will also make the sucky noise loved by those who like such things! Some cars with mass air meters don't like induction kits. Yes, I know about Ecotek valves, no, I don't feel the need to actually go and buy one myself.

Question: Hi there I have a 2wd Cossie with greens 3bar k@n s/s -31 group a d/v stage 3 chip 4x4 intercooler T3 turbo the car will only boost to 15 psi the amal valve was knackered so I swopped it for a bleed valve I have 2 -31 1 will hit 15 psi hold there all good but not go any more ?other hits about 18psi then drops to 15 psi any ideas also how much for a tune up if u think thats the probs thanks
Answer: Hi.. is your T3 a hybrid? If one actuator holds a bit more boost, then it must have a stronger spring in it, or the adjustable arm must be shorter. You could opt for an actuator with a replaceable spring. I'd need to know more about your engine before I'd recommend running more boost. A RR session costs ?50 plus vat.
