It's a 3 door cosworth the spec that I know is

stage 3 msd chip L6
3 bar map
T34.63
Dark greens
500 cooler
Group A filter
044 pump rewired as well
Freshly built engine
Ported head
4" rolled out scorpion
I think that's it lol

750hp escos

Should do an easy 350/350 and with the map tweaked after you could max the greens out and get maybe 370 hp..

That engine to me is crying out for some 55lb siemens and a bd 14 inlet cam !!

Would do 400/400 then..

Would this be reliable power or likely to break a lot lol

Cool how much is a cam and 55s

I guess I will need a new chip as well

Keep the current setup, the 205 block will only take so much so I would not push it. Its good and reliable what you have now I think..

750hp escos

All depends how good the lump is but you say its fresh so the car well set up and it should last well mate..

Sell the greens and chip and get new chip and black 55s..

If you dont have valve pockets then you cant go bd14 but can go ab07 with out valve pockets..

So chip and blacks from stu cam from newmans as he is cheaper than anyone listing ab 07 and well set up and it will be a little flying machine!!!

Oh yeah the head has been ported for 500bhp it's all been rebuilt new stem seals valve guides etc

nixon_2wd

I dont believe so, however a longer duration camshaft will reduce the dynamic comp ratio hence lowering cylpressures. People tend not to change cams on these setups and so the high dCR combined with high boost cracks the 205s.

gjh

So how far can a 205 be pushed then, 370?

jamie's

mines been on 420 bhp for years and never had a problem with it(well not the
block anyhow)
