Just get a machine shop to bore them out..cost about£20 and fit a gtir thrust bearing...i run an excedy carbon from a 200sx on my car with the same mods.
Motec m48...love motec you buy an ecu and yhen have to pay again to have the features un locked..the syvec s6 is a better unit and you can run certain coil on plug setups on it which is a mile better ign wise than the distributor systems as you can run larger plug gaps...this gives you a better...
Well that is to do with velocity of gasses...something that happens with big ports and cams is that at low rpm you get reversion of gases back in to the inlet and low port velocity...meaning a poor idle and the engine not being efficient and there for the turbo will spool slower or later in the...
Rule 4 cam timing and type and valve clearences will affect compression test readings...some people think there engine is worn out when it is not due to doing a compression test...leak down testing is the only reliable method to test engine wear without stripping it down, if your cam chain is...
Rule 3. Oil grade and temps...fact oil should run at 100 degrees and above not below...why? So that it can evaporate the moisture and petrol dilutants in it...if it does'nt you will be wearing your engine out as quickly as using cheap oil due to the above and also from the oil being thicker than...
Rule 2 pistons...use the correct grade of alloy for your goal...i.e most people fit forged pistons...how many know that there are differing grades of forged alloy to suit differant power levels..higher power equals harder grade alloy and bigger piston to bore clearence...which means faster wear...
Ok will start with cams...rule no 1 use the cams to suit the rev range of your car...fitting really aggresive cams is a waste of time on a car that has a low rev limit..260 degree ish suit almost every one who has a stock rev limit..all that happens is you will narrow the usefull power range if...
Well you never know lads...i could give out all the specs and then you can all have reliable power if you follow it, ed is the best lad to map them and if you cannot do it then get him to set the cams too.
