oversized pistons(3.5 mm i think?)gives pretty close 2 litres.

If your going forged pistons anyway I would bore it rather than stroke it. Could also do both, just get the crank offset ground slightly. Would then need undersize bearings, not sure on availability.

yeah i know you can get oversized pistons but wouldn't that raise the compression?, unless i used a decompression plate

Difference to compression ratio would be minimal, and pin height on pistons could be set to suit whatever compression ratio you want. Shorter stroke to bore ratio also gives more revability.

if you dont want lag, i would suggest using something a little bit smaller than a gt40. 
generally the way to avoid lag is to use a correctly sized turbo.

If you really want such a big turbo, why not go twin charged?
Eg SC14 to provide low down boost and help spool up turbo, and turbo only for high boost. OR you could run anti-lag.
Anti-lag is really only suitable for race cars, and I tend to agree with shinybluesteel. Just use a correctly sized turbo to begin with. The giant turbo thing is a bit of a wank factor for street cars.
If you are getting forged pistons, just get ones with a deeper dish to lower compression. Once you start playing with decomp plates and changing gudgeon heights, it completly stuffs squish height. Squish height is important to preventing detonation. I.e. you may have lowered the compression but the increased squish height also increased the likelihood of detonation anyway.
Custom cranks aren't cheap (probablt 3G plus). And you are better off with a shorter stroke at higher revs.

so would be better just to get the forgies that are over size and have a deeper dish and look at getting a gt28, gt30 how much kw would you think the 3tgte would be able push? it has an ems, want to get a custom plenum and exhaust manifold and properly tuned of course
thanks for the advice fellas, josh

just a suggestion, i mate has bored his 3TGTE to around 2L and used hepatite gemini 2L pistons, i would think this would be a cheap mod for extra power, also reduced the compression down to around 7:1, perfect for any high boost application. i don't have many details, just knew he used standard rods, and left the HG the stock bore size otherwise they apparently blew all the time.
