Iv got a s2 erst jus had my bottom end done all forged wot do i need to get this sort of brake was running 187bhp/205ft/lb on mfi but im gona b using aftermaket managment ie omex 600 any ideas all welcome but i am staying cvh cheers

chaffe

.48t3 or t34, big enough injectors, and a decent cam, easily achieve that figure

diamondrst

Wot sort of injetors/cam would u recomend mate how laggy r a t34 would a gt28 be a better turbo as in lag??

studabear

nms cylinder head like karlos has?

chaffe

gt28 would be a good choice, any injectors that flow enough fuel for your application will do, the choices are endless. t34s are a bit big for the old 1600

diamondrst

How much are these

chaffe

do you Really need to modify the head for 250 bhp? thought standard was ok up to this power

zetecherb

im liking this thread i was running 170bhp when my car blew up on dyno but as ive nearly finished rebuilding im hoping for about 210ishbhp so im gonna be keeping an eye on this thread

chaffe

blew up what was the problem?

Cossie T3 would be my choice of turbo, newman cam, and whatever managment your tuner prefers. Speak to Jano @ Oddkid creations, he's extremely helpful and very reasonable too! http://www.oddkiddcreations.co.uk/

chaffe

cossie t3 being a .48 ar exhaust and .42 compressor?

So surely a stage 3 t3 would be better... 55trim comp?

chaffe

a bigger engine would be better IMO lol, but you can only piss with the cock you have lol

Rogeyboy

iTrader: (2)

Well yeah obviously a bigger engine would be lovely, but he wants to stick with CVH and people were advising on what turbo to use... Surely a stage 3 turbo with a 55/60 trim comp housing will flow better and make more power than a standard .42 trim housing?

diamondrst

I have a stage 3 t3 on it and its very laggy comes in at 4000rpm but it goes lol would it b sutible for 250bhp i would go zetec turbo but not sure what has to be changed as in engine mounts

chaffe

thought you just spent money on the cvh? zetec will bolt straight in but its a completely diferent engine mate

diamondrst

Yhh i have but that can always be kept lol i thought the mounts had to be changed so i can drop a zetec turbo engine in and run it on rst gearbox until the gearbox blows up lol?? Dnt the engine mount hav to be modified?? And 250bhp on a zetec would b easily achievable am i right in thinkin that

chaffe

mount is the same, just use two bolts instead of three, never had a problem yet

zetecherb

it basically spun all its bearings whilst being dyno'd and lots all oil pressure lol

chaffe

ugh ffs typical

diamondrst

Does the gearbox mount up??

chaffe

yep, you need a 1800 flywheel though, get an rs turbo 4 puk clutch too

jessie_rs

4k??? are you sure thats terrible my cvh is running stage3 head big valves, newman cam, green 803's grs front mount and t34 mapped by msd 20psi comes on boost just before 3500rpm. Its never been rolling roaded but its a comfortable 240bhp all day long.

I had a stage 3 t3 before on same spec engine .48 exhaust housing and was nowhere near 4k untill it came on boost. It was so responsive and makes me want to change back to it instead of the 34.

diamondrst

Does the flywheel hav to be drilled

chaffe

nope, clutch bolts straight on, did one last week

In answer to the OP....
For 220-250 bhp with his setup will just need a Stage 2 T3 (.36/50) for up to 230bhp or a Stage 3 T3 (.48/55) for up to around 270bhp this is assuming you have a FMIC and suitable injectors.
IMO a T34 or GT28 are too big for that target BHP.
Stock head and cam flow enough for around 250bhp, then port work is really needed, my NMS head for just the port work was around Ł350 but I also had SS valves bronze guides etc fitted at the same time so paid a fair bit more.

chaffe

Hey Karlos, where have you been lol

J1mbo

iTrader: (1)

My spec that gave 252 bhp at 6000rpm and 255lbft at 4000 iirc

2wd cossie t3 turbo
Standard bottom end
Nick waples ported head and kent cam
Matched inlet
And mapped on pectel t2

That's all

And it flies

It runs out of gearing regularly lol!

forget the cossie 2wd, get the 4wd one, 60 trim

Karlos G

iTrader: (4)

lol

J1mbo

iTrader: (1)

Why would you want a 60trim?

Herbo747

hey jimbo what boost were you running to achieve that power ect on the 2wd cossie turbo, i have got a similar set up on my zvh and mine made very similar numnbers, made 250 hp and made 248 lbft torque at 1 bar boost.

LEE-RS

not bad mate, what head you using ?

Canada1

A standard head and cam might make close to 250 hp, but at very very high boost levels.
Karlos has a well ported head and performance camshaft and still required well over 1 bar boost to make 231 HP.
I really don't see a standard head making 250 HP - unless its on one of those "funny numbers" dyno.

You mean one of these dyno's Perry?

J1mbo

iTrader: (1)

Herbo peak power was 22psi peak torque 24/25

We just mapped a engine for a guy, STD head STD cam, forged bottom end 2wd cossie turbo on .48 rs turbo exhaust housing

Made 250 at 25 psi at 5500rpm

MO' BENT RIMS

forget the headache in the end your going to drop a zetec turbo in it so forget the hasslle drop it in and it will be the average jap killing machine !! by the way if your putting a gt28 or t34 on your cvh dont bother. either get a cossie t3 or get a GT25 turbo minmal lag nd will still make good power

Canada1

LOL really?
standard head and cam? no way!

J1mbo

iTrader: (1)

My brother has just corrected me sorry it had a slight clean through the ports, srry about that, but still STD cam!

Those figures were on out 901 superflo dyno, no rolling road figs either lol

Canada1

Hello Jimbo,

A propper cleaning of the ports, removing casting flash, and those terrible sharp machined edges make quite a difference in the heads ability to make power.
What management? standard ford? efi? Mfi?
Intake manifold?

Starting to sound a bit modified. I can believe 250 hp from a modified 1.6
