I am just wondering what some of the more cost-effective 2v 4.6 builds are. I am looking at building a motor for my brother.

His is a 96 2v 4.6 GT 5-speed. Im just not really sure what the most cost effective builds are for these motors. Supercharging is expensive and cams/ heads are really pricey, and don't offer particularly great gains.

I am considering going with PI heads/intake, new ignition and fuel systems, and building a mild wet-nitrous motor, with part totals hanging around $3500 with all new parts. It should put down around 450+ at the crank but im not particularly sure how well it will hold up, as i would try to retain the stock block and internals.

Anyone know of an partiality cost effective ways to make them put out real power at a decent price? Im not really interested in one-off junkyard finds or hard to find used combos, Im looking for something practical.

realistically i would like to end up at 400 hp+ at the crank. Any particularly common blowers at a decent price? Motor swaps?

Just looking for some outside opinions.

if you plan on going 450 to the crank that would equate to (I could be wrong) to 410 + to the rear wheels. If so, I would suggest getting forged internals in her.GL!

It will last for a little while, mine lasted for a while until a rod started knocking but my original bottom end had 125,000+ miles on it when I first did the swap. And as far as getting that much HP, Sport Truck Magazine took a 97 engine and put on a set of ported PI heads a stock PI intake and a set of Comp Cams XE270AH cam which is a 550 lift with a 270 duration and put down 405HP at the crank. So really with the right combo I think you would be able to get close to what you want without the spray. If you plan on spraying it though, I would definitely go forged the first time and forget it.

-Piece together a used blower for around $2500. This might take a while however.
- P.I. swap is like $400 bucks (maybe less) on Craigslist. Look around.

What are your plans for this car - daily driver or track monster? Depending on what you want to accomplish, there are lots of options. You machinist will be a good source of information to help you sort reality out from the marketing hype. Optimizing intake airflow and proper tuning are a real great place to focus first.

Have you thought about converting to 4V setup?

If you wanna take it to the mid 400s with RWHP, your going to need a built short block, which combined with a power adder and a tune is going to be out of your price range of 3500$

Get a forged rotating assembly, I had a low mileage car when I went boosted 13#s just over 400 hp.. Ran strong for a while but it took its toll. I recently had 2 plugs blow out (which I checked regularly for torque). the motor also just starting knocking a bit, I am in the middle of a tear down to see what it was and whether or not my block is re-usable. everything was good till I started spinning to 6500-6600 rpms... Stock heads/cam/springs did not like that.
