What do you want out of this car? You would gain a lot more bang-for-the-buck by supercharging a 2V than doing a NA 4V. If you're still serious about a 4V swap, I've got a ton of information about blocks, heads, cams, and etc.

My final set up would be twin turbos. i would greatly appreciate the info.

You could make retarded power with a TT 2V. More than enough to be completely useless on the street.

yea but the 4v engines seem to have needed less work

4v would not need less work to make equivalent power. Both would need forged bottom ends. Asilver2001gt's car has stock 2v heads and a kenne bell. Makes 600 to the tires on a conservative tune

Both will need a forged bottom end. If you want to do work to the heads and custom cams, the 4V will just end up costing a lot more money.

so with the forged bottom end and the 2v heads wat would be max amount of hp i could push it to compared to the 4v 1000hp w tt?

well it will take more to make a 4.6 2v to get around 1000 hp. but it is definatly possible. but i read an artical where they got a 5.4 navigator and forged the bottom end and ported the heads, along with changing the compression and cams (stage two). anyways they put a single 67 mm turbo on it and it made an easy 1002 to the flywheel with 17 ponds of boost.

but on the other hand i read where they got a 98 4.6 block and the non pi 2v heads and it made around 713 hp with twin 57mm turbos. but they ported the heads and put cams in it. thats not to bad for a 2v

but its all going to be expensive no matter where you go. modular motors are very expensive compared to the traditional pushrod motors.

but if you want to make some good power cheap id say kenne bell it and forge the bottom end, you will definatly make an easy 500 hp. but thats my opinion

MPH had a 2valve that had a KB 2.6 I believe and they put down ~830rwhp...and supposedly that was with only 7 cylinders.
