with 5k buck you can go forged and n20 or non forged and s/c or buy a 03 cobra motor and s/c with tranny...

or build a badass n/a 4v forged and be ready for some serious turbos or other FI in the future

sounds good, but personally Id go vortech (bc thats what I did bc imo the vortech is a better unit, less problems, higher max output and uses a return style oil feed (which is a good thing)... both the s-trim and procharger are essentially the same output wise, I have seen higher numbers from strims in general, and also the T trim upgrade is very easy... with 5k bucks you can almost get a forged shortblock and a non ic S-trim blower and be around 400rwhp, and then slap on a intercooler and push 550-600rwhp with head and cam work

Ok show me where he's running 400 rwhp n/a. Last time i saw his dyno numbers he was doing 340 n/a. Its impossible to get 400 n/a on a 4.6 2v. We just had a thread about this. You cant just get a short block and throw a 300 shot on there. It doesn't work like that. He spend so much money on suspension and safety and things like that. Im telling you if you think for $3500 you can have 600 rwhp no problems then you're dreaming man. You cant just say well my short block makes 300 rwhp so if i add a 200 shot it has to be 500 rwhp! 300 + 200 = 500 so there ya go! lol its not as easy as it sounds.

Seriously, you could get an MMR forged short block and build a Vortech system for around $5k. You'd have to do the install youself to get there, but it can be done. Check out the sticky thread in Pipes Boost and Juice to see what I'm talking about. I have my entire S trim system and I have spent $1500 including gauges. Another $120 or so for a fuel pump and I'll be set. It's worth taking a look at.

Just as mike at custom performanc in Charlotte NC, better yet ask anybody with a 150 wet shot on a stock 2v... youre way off on this one

he was running 342rwhp and he said his new goal is 380rwhp. 50g's or not hes spent alot of money and trying to make insane numbers with N/A. its not going to happen on a 2v 281ci motor. a blower will easily put you at 400rwhp. when u start gettinghigher with a stock GT your gonna be looking at a tranny, rear end, and internals in the near future. its not unreasonable to get 500rwhp if you forge the motor and get a stronger drivetrain. would probably be wise to go ahead and replace the heads while your forging the motor, and while ur at may as well throw a cam in.

but with all thatmotor workthere are better options (forged 4v cobra motor, 5.4dohc, etc...)

Then find me someone. Find me someone thats making 600 rwhp on a 2v 4.6 without a blower that hasnt had major extensive work done to their car. And everyone in every podunk speed shop is gonna have their own opinion. Ask some big boys like THR or MMR. Its possible to make 600 rwhp with just a built motor and spray but its not easy and its not as easy as just throwing on a 300 shot with a built block. Man where's Mitch or Zach when i need em!!!
