Vtec question and Swap

[saidguler]

thnks bro I got some ideas in my mind now I not looking for the fastest EP3 or something like that even 200-250 hp is enough for me just wanna feel some power.

go on k20a (or whatever that website is), there's prolly a used jackson s/c you pick up for cheap...installing an sc on an ep3 with i/h/e and kpro should give you exactly what you're looking for in terms of power and you'll wreck mustangs and most stage 2 wrxs with it...plus an sc is way easier to install than a swap and all that.

Do what I did. Buy a cheap k24 ,a turbo kit and make 350whp :). the supercharger with the 4.0 pulley boltons and kpro ur looking at 221- 228 whp... I made 221 when I had that setup

4.0 pulley is like good for 4 psi, lol...go 3.6 or 3.2...you'll easily crank out 250hp

Completely wrong. The 4.0 pulley plus the ep3 crank pulley makes 8 psi. You can't use a 3.6 or 3.2 with the a3 and a Jackson racing supercharger because u will be spinning the blower passed its limits and completely blow ur motor. The smallest u can do on a ep3 is a 3.8 pulley that u can order from pulley boys. And even that pulley is pushing jrsc to its limits. U will need to run a methonal kit or an after cooler to compensate for the the amount of heat that pulley will produce , or ur gona have to reduce timing which at that point ur better off just sticking with the 4.0 pulley. Different pulleys matching with different crank pulleys are gona net u different pounds of boost. For the ep3 ur choices are 4.4 pulley = 4-5 psi ,4.0 pulley = 7-8 psi , 3.8 pulley = 9- 10 psi

woah...you're so right. I confused it with the kit found in the k20z3 that uses smaller pulleys like I mentioned to achieve the boost levels I was talking about. Thanks for keeping me honest.

Haha no doubt. All I know is the a3 and now my a1. Any vtec k series I know jack about lol. I have a type s but its my daily. Stock except an intake. That's why when people come on here and ask how to up the vtec on their a3 I just shake my head.
