what sort of power am i gona be looking at from a stage 3 head mahle 0.5 pistons 31 actuator collins chip wth a standard but reconditioned turbo high lift cam and an adjustable boost valve + what else would i need to get 250bhp

 

you will need a better turbo [stage3] an efficent intercooler, re-worked bottom end and good fuelling.

you will need an uprated gearbox and other bits and bobs

wouldnt like to venture a guess to what power your running but who set it up?

 

like said above ur limited to your turbo, i doubt its any good much over 14 psi so as at the moment on your spec i would say 160-180bhp depending on injection system and how its setup,

250 bhp will come with as said a stage 3 turbo, 20 psi+, grs,pro alloy etc i/c, proberly a 5th injector, may get away with it on your bottom end providing u have arp bolt set in it, but at high boost ur better off with low compression pistons

 

I'm making 250 bhp on a stage 2 hybrid turbo at 25psi

See my sig for the rest of the spec. I would say 170bhp would be reasonable for what you have at the mo.

 

170 on a stage 3 head? On 4 psi maybe

 

i forgot to mention i also have a pace double core intercooler and its on about 14psi at the mo, im yet to fit the cam and recon turbo i was just offerd them for a good price so i woundered wether it would be worth getting them now or saving up for better bits later, its summert near 170bhp at the mo, wot sort of money is it to get a 5th injector?

 

5th injector isn't really necessary at this level of tune. Mine was only added for peace of mind once everything else had been done and we decided to throw an extra 7psi through it. Do you have the big Pace kiddie like mine.



If you have the smaller one you will be limited as mine just seemed to choke at 200bhp with silly high ACT's

 

mines only the smaller 1, i think im just gona fit the cam and s2 turbo for now with the edition of a stage 1 box for good measure.
