go with some forged rods and pistons, rebuild everything else to as new and stick some aftermarket ecu on it running sensible boost should see my target no probs with a decent turbo.
so then comes the problem of the transmission, the best paddle clutch ive seen so far is only rated to 260ft'lb which is going to be on its limits so not the best choice.then the gearbox and driveshafts what upgrades are avaliable from other models?

no
The 1st gen 4agze(AFM) is the same as the 2nd gen 4age internals
The 2nd gen 4agze is the same as the 3rd gen 4age internals(small port and oil squirters)
The 3rd gen 4agze is the same as the silvertop 20v bottom end, small port head.![]()
(oil squirters, etc, best engine to own)

nope,
The early charger set up is AFM, so boost as much as you want
, the later set up
(gen2 4agze onwards
, with the oil squiters) is map sensor and fuel cuts at 14.7psi
(I don't know this for definite, just from reading, but quite plausable)

The N/a box eats itself at 250bhp

Yes.If you see what people do in Australia and America it's quite amazing how much power you can get out of these little engines

Yet to hear or see any that lasted any significant length of time,reliability is a major factor with a tuned engine like this.It really isnt a simple or cheap thing to do,you will be looking at thousands of£££ to build something that will not only support 250bhp but also stay that way.

Tuning a 4A to 250-300hp is right at the top end of its engineering window: the Atlantics run 250, but get rebuilt after each race..

You'll need every component to be in tip-top condition, balanced, etc..
