What would be the ideal turbo engine build-up from scratch if you were to build one for the road? i.e pistons,comp ratio, cam etc?

Reliable fast road Turbo motor -
A+ block {surface ground}, +.20 rebore Omega cast Turbo pistons, A+ rods & crank {reground if needed}, lightened steel flywheel and backplate, grey diaphragm + rally/race plate, Piper phase 2 cam, duplex chain, Avonbar Turbo oil pump, modified head {36/29 valves}, standard Payen Turbo gasket, A+ "Y" head studs {head & block tapped for 10th & 11th studs}, Trannex twin pin diff, sc drops, standard box fully rebuilt {properly !!} & a good intercooler.
Providing it's built properly a decent Turbo motor as above, will be a reliable road engine capable of 130+hp and thousands of miles. A well built engine is the key to reliability, not just a load of fancy parts !
Now if moneys no object, and you want an all out monster, well ..........................

...
Minispeed
Turbo 9.4cr with 11.3cc dish available in 40. P22357S
£235
No Picture..
Surely the second ones would be better in +040 because they hasve a bigger dish..
which = lower CR and more boost can be applied ?

I finish at 4pm so i'll do it as soon as I get home!
Ain't making no promises! As you know my mechanical knowledge is that of you average Organic Banana but they defo ain't a standard dish. I hope!!!!
I'll MSN it up if you around about then and if they are right well talk prices, because i'm down in Plymouth from the 27th so might be able to save ya on postage!

the number is usually cast into the INSIDE of the piston when you look from underneath!

it's a bit of a dirty little begger! I'll clean it up 2morrow if I get a chance! Do I need to take the rod off to see it?
