Up grade time I think

[VXR HEED]

I just went for a run in my monaro and I past a young guy in a 03 focus RS and he wanted to play so I obliged but dam he was on my ass the hole time I did manage to shake him but it was hard going. So I have decided that I need more power and a lot of it. I've got a harrop 112 charger non intercooled on it with 5psi pulley. I've looked in to a tvs2300 setup with cam but it's to much money to be spending right now that the plant for the future. I was want to no how much more power I would get with a cam, meth injection for cooling and 8psi pulley and remap. Will it survive the stress?

Considering an LS2 with heads and cam should be well north of 400rwhp anyway you should be closer to 500 if you added an intercooler and did things right.
Your blower is small so will eventually end up restricting airflow.

If you google about you will get some interesting feedback like "Just so that you have an idea where you stand I got 375 hp out of my 2004 with a M112 on top otherwise stock. With a FM7 cam, Meth and Shorties I got 425 hp. With my latest setup M112HH 1:1 rear, 3.1" front, LT's, Stage II heads, EDC cam and meth I get 514 hp."

You are probably better getting shot of it to someone else wanting a feeble upgrade and getting a larger unit and cam. Though you might also need to upgrade fuel system, clutch etc...

Best to decide where you want to end up first. Proper heads and cam will put you about 50rwhp ahead of where you are now without the blower. So you might even be able to do the upgrade funded by selling off the existing stuff

If you want more take a look at the TVS2300 or venture into the world of hardcore NA engines..

Oh whichever path you take, dont forget your wallet.

What heads are the one to go for Ringram? I'm thinking about starting from the bottom and working my way up.

Easy cheap(er) option is upgrade what you have with a Cam

The cam is going to happen regardless this winter but I thought about I could probably stretch myself to heads as well then next year take the plunge and up grade the supercharger. Does that make sense or and I dreaming

To be fair that focus must have been up rated to within an inch of its life!

To be fair you can get those things to go very well indeed. No shame in a tuned one keeping up really although once you get into high mph numbers most hot hatches fade due to a lack of torques.
