Supra is at Hyper sr for single turbo

Just going off what the mechanic said he was going to do not sure why he is doing this my head is not warped the engine has only got 58k on it so in very good condition

58K on the engine is good so the bottom end ie shells and crank journals shouldnt be an issue, i still cant see any point in skimming the head if its not warped.

I've always been told you never split an engine unless there's a need to do so....

I may therefore be showing my ignorance but why would you have the head off an engine with only 58k on it? I wouldn't have thought the valve stems would need doing that early would they and even if they did I was under the impression that this doesn't require the head coming off anyway?

And why are you having the valves cut back (what does that even mean? I've heard of fitting larger valves for increased performance but never cutting them back and just interested in the reasons/benefits)?

Im in the same school of thought and if it aint broke dont fix it lol, it does seem a little strange taking it off to do jobs that at 58k shouldnt need doing, if its playing safe then you might as well pull the motor out and do the whole lot !

I can see cutting the valves in being a good idea but i'd have had it leakdown tested 1st which would have showed if it needed anything doing.

All the best Adam and hope you dont think im getting on your case, just dont want you wasting your hard earnt dosh.

Just having the uprated headgasket to prevent it going in the future paul told me when you remove the head it twists slightly so thats the reason you have to skim the head thats what i have been told and the thicker headgasket ends up only been around .5mm thicker than stock headgasket so not a major difference, he has also done the leak test before removing the head and all is fine i trust his judgement on this and Dunk i do not think your getting on my case your like my older brother much older lol

That's strange. When CW rebuilt my engine, he knew it was for a single turbo but he used the OEM headgasket
