All steels have endurance limit of 10 million cycles.If the part take that (at some definend max load) it will last forever.However even few overload cycles and the game change.. Properly designed steel part (for the task) will last longer than you.

Too easy conversion is to put Zetec block under CVH head (2-litre CVH).Makes fun Escort.. Friend had one turbo example;made 330 hp little over 1 bar boost.Of course I had ported the head

That is the curse;old trustworthy manufacture mark is sold to some greedy investor.All sudden the good quality tools are crap but the company can ride on the old reputation.For a while.. Nowadays you can't know who owns what and do the tools be what they used to be. Of course it's poor busines to ma...

"I think that I know it all but then I read Speed Talk" T-shirt would be great!

Supra 2JZ I ported the head come Friday to local Dynoservice,make 1250 hp and Saturday on the airfield run mile at 360 km/h.Driver told that it was the first and the last time he run;he was so afraid that the Supra get airborne!

Great that som...

Ehh.. never solder the Lambda wires;the comparing oxygen comes from the lambda wires (where the actual sensor makes the measurement of the exhaust) "The probe The sensor element is a ceramic cylinder plated inside and outside with porous platinum electrodes; the whole assembly is protected by a...

Just the thing to remember;the woodruff keys are not to keep dampers (or anything else) stay put;they are just locating devices.It's the bolt tension or interference fit to keep them staying put.

If Don Terril could run the forum like this why someone else couldn't do same?
Small membership fee is OK if needed to keep this in hands who love this but sold to some greedy company and this will die..

I got a customer bring freshly honed Volvo block for assembly.First,the block was oildirty outside so not washed,crank was in the block,honing grit showing inside the block
The machine shop had said that it was ready for assembly..

Just a waste of gasket to use it with those spacers;in fact it will nullify the whole idea.

Are the bolts same in both rods? If so then the other have also different caps.Are there any significant differences on the weight?

Why the Pipemax shop needs to be in Seattle? Never heard about Internet?
I have only 3.98 Pipemax and found that anyone is not willing to pay modeling the engine to make correct exhaust
