ok the BEAMS is a good idea but turbo'ing it would cost more than its worth. finding a blacktop BEAMS is hard enough as it is. they can be modded to the high 200's low 300's N/A on TRD parts alone though. another really cool option would be to go with a 4agte. basically this is a 4agze (supercharged 4ag) with all the SC parts taken off and a huge turbo slapped on (the GZE block is bullet proof!!) its got forged crank and rods factory and a 8.0/1 Cr cast pistons(like the sr20) so lots of boost!!. turbo'ed they have made past 400whp and the motors are VERY light compared to a 3SGE and will spin alot higher. if you find that later AE101 GZE they have a slightly higher Compression (8.9/1) along with some other minor adj. and if your looking to make more tq you can swap the block/crank from a 5af motor and a porsche 928 timing chain and you got a 5ag strocker kit! this will all also be VERY CHEAP!! GZE short block $300-$400!
