i've got a 96 gt w/ vortech s/c and support mod's. making about 400hp. now for those of you that are seriously into cars, you always want more power. now i need someone to tell me about an engine buildup for my car. i'm using my stock block, and i'm gonna send it off shortly to get bored and decked. first off, i'm looking to make around 800whp on a twin turbo setup. i'm wondering if getting it bored 20-30 over would be a good idea. i will be ordering a forged crank, pistons and titanium rods. is this good for bottom end? the heads i'm not sure about at all. what's a good bore on the intake/exhaust? how about a cam setup and rockers? remember it's a GT w/ SOHC. does anyone know anything or have a website that would explain a good setup for this amount of power pushing between 14-18 psi. the motor i'm building will be good for 1000hp. i've done some research on this but there are too many people out the with to many different idea's, which makes me wonder what the best setup would be to be reliable and make big power. thanks.

You cant make 800 rwhp with a 2v. Thats that. end of story. Not even with a twin turbo and nos. Its not possible. There is a wall you hit and its about 750 hp. And thats with a stroker, twin turbo, nos, methonal, and a lot of custom intake work. Go 4v and you might be able to achieve these goals. That or go with a fox motor. 5.0

Nothings impossible. My friend has a stroker 2v with a kb pushing a little over 600, with no nos or methanol. He's spent an assload of money... but its possible. If he had a turbo kit instead of the kb, he'd be probably in the neighborhood of 670rwhp, without nitrous.

Its true. But talk to code. Its easy to make 600 hp. But you just cant flow enough air through those 2v heads. Even the best biggest ported 2v heads cant flow enough air. Its not impossible but it will take all custom work.

not to talk **** to anyone but i've seen a 97 gt with stock motor, forged pistons, 90mm tb, etc.... run 850whp.... now how is this possible when you say it isn't, i've seen it in person. granted he did have some custom head work but still, nothing that i'm not gonna do. i realize that 850 is alot of power but it IS POSSIBLE. if anyone can help me with the ENGINE build-up please let me know. dont tell me it's not possible when i've seen it done.

I also was gonna say anythings possible, just gotta study your stuff... good luck with your project.

Ok first thing is to bring up the cubes as much as possible. Use a forged stroker set up. Forged stuff of good quality should hold up around 1000hp, but remember that billet is better. If you can find titanium rods use that! Lighter=faster=more hp=less resistance. You want the bore to get big. Now with that said because of the actual iron thickness in the bore you will need to use some high quality sleeves that can hold up by themselves. I myself like Darton sleeves, but there are many out there the goal is to use the best. You will want to use the biggest bore you can, and may even need custom pistons made, a racing machine shop should be able to do this. The block should still hold up at 800, but you will want only the best hardware to peice it together. Use studs insted of bolts everywhere you can. Also a girdle support will help, but I would use an aluminium girdle brace as the aluminuim helps dampin the harmonics generated from the crank, even if the motor is balanced. Now for the heads. If you use a big enough bore you can do some major head work. The goal here is to unshroud the super shrouded valves and then some. The combustion chambers will need to be cut around the valve to open up for more room and flow. The valves will need to be changed with larger ones. 1mm over on the intake alone isnt good enough. Also in my opinion the ford racing heads for the 2v 4.6 are more head than a pi head could ever be. They can take way more porting than a pi can and will flow way more. D.S.S. offers these heads and there flow is pretty insain. They already have bigger valves and I think they can recut and upgrade the size even bigger. Also you might look at Jesel, they make some new trick stuff for the 2v heads. The bad part about this is that you will be limited on intakes because the port design is similar to non pi in shape. But adapter plates can be used. Also the highest flowing plenum and biggest t-body you can find. Lastly you will need 20psi or more to get there. Twin turbos are the way to go with custom headers and intercooler. Maybe even a tune for race gas. 850hp on a 2v is pretty high but it could be done. If you got the $$$$$$$$$$$$$$$ you can do it. Just make shure you use the biggest of everything. Like my dad says, "the bigger the power, the bigger the explosion!" why would you need anymore than 550hp on the street anyways, thats my question.

Ohhhh, I wouldnt go as far as saying that, but yes it will be a difficulr journey. Of your wallet is deep enough, then MANY things are achieveable.
