I have a Mk2 mondeo with a 2.0 zetec engine. It is currently getting a turbo conversion and want to know what the best amount of boost i should run (psi).

I will be running the mk1 Focus RS turbo, manifold ect, intercooler standalone mangement, loom, bigger injectors ect, however I am not lowering the compression yet as I was not going to run anymore than 10psi. I am still running the standard clutch and internals.

With this conversion what is the best PSI to run so that my clutch will not slip, i will still have traction and internal can cope.

Thanks guys

It may slip at that mate

Yeah thats what im worried about. The first thing I am doing is the clutch (but that will be when I have the money and will not be for a few months). Any recommendations on how much boost I should run to be safe?

6-8 psi over in the states u can buy turbo conversion kit's which includes turbo, manifold injectors intercooler ect al 2 be used on standard internals they all say 6-8psi boost. Also if u look at powerworks super charger kit for the zetec they run at 8psi on standard internals and u can get a bigger pulley and up the boost wen you've get forged internals. So 6-8 psi m8 play it safe.

burnzy

what sort of gains do you get with 6-8 psi will there be quite a noticeable increase in bhp?

and keeping all the internals and comp standard does that mean you'll have no lag?

edit: sorry to thread jack

Roughly 200-220 bhp

here u go chek that out http://baileyperformance.co.uk/

depends on the spec of the engine really and the mapping. But roughly 200-240bhp the later bein much better speced eg front mount cooler cams bigger tb custom plenum ect. But if Ur not paying out 4 forged pistons and rods i dare say it's a pretty basic spec?? So id say low 200's at 8psi

mondeo2000

Thanks guys, I have been told that I will running about 200-210bhp on standard internals, intercooler and standlone mangement, stage1 cams and bigger injectors with about 8psi boost. Im a little worried if the clutch will cope but i will find out in a weeks time (its going on rolling road so will tell you the results)

My plans are to uprate clutch, lighten flywheel and better brakes, then I will move on to lower compression and run more boost, however then i will have to look at limited slip dif as my car will just spin as soon as turbo kicks in.

Thanks again for all your advice

cheers for the info lads just wondered i always thought there was no use in low psi conversions but looks like quite a big bang for buck, personally i dont no if i'd risk using standard internals, but guess it all comes down to price.

focusrrx87

mine is bein built now spent about 4.5k hoping for 300bhp at 1bar 350 at in the 20's psi. Although I'll only do that on the rollers. Lol iv got a stage 4 6 paddle clutch and ford racing lsd 2 help get the power down forged bottom end alc bearings it's 2.1 now also. Goin in on may the 1st cnt wait

that lads made 328bhp the only things he did is forged pistons,bigger injectots,m/s ecu with cosworth t38 turbo cheap as chips

focusrrx87

at what boost??

rich123

lol its the same chap who mapped mine did that escort got realy good results from that

mondeo2000

Focusrrx87 I see that your in Kent, any good places that will help with my Mondeo when I get it back? Need a paddle clutch done soon, then will being lowering compression, LSD ect

crazycage

on that turbo on 22psi thats shit.

clarke5700

realy how comes? real question btw

focusrrx87

conaught competition engines in sittingbourne they deal a lot wiv ford engines.

crazycage

because thats a lot of boost and a big turbo ,i would want a lot more power than that

clarke5700

i thort a t38 was just a t34.63? a mate of mine made 397hp on a t34.63 @30psi so terned down to 22psi i would expect 330ishhhh

crazycage

no mate its not

mondeo2000

Ok thank you, I am in Maidstone so Sittingbourne is not far from me at all. Thanks again mate

focusrrx87

Im also in maidstone shepway.

focusrrx87

crazycage wot did u make at 1bar?

clarke5700

okkk can you put me right then??

crazycage

bigger rear wheel.

crazycage

over 300 but on a smaller turbo why ??

clarke5700

ahhhh right thanks sorry if ive upset ya

crazycage

what makes you think you have upset me ??im cool.

focusrrx87

Just wondering thats all as i building mine. Jesus dude u need a chill pill. Lmao

clarke5700

i donno ive never met you but you seem very blunt/pissed off in all your posts? or maby its just me lol

crazycage

not pissed off mate, but i am blunt thats just how i am but it come across more so on the net .

Rs Cosworth 1

Imo.

If your doing that do it right

Fully forged bottom.

It's the way i think about it,Yeah it'll be ok for a while but trust me the lust for boost will grab ya.So why not strip the engine and fully re-build forged Do it right first time less expense

both the wheels are bigger, its named on the size of the front wheel, ie; a T3 & T34 normally use the same shaftwheel (shaft & rear wheel are one part for those who dont know) but the T34 has a bigger compressor wheel & housing. The T38 will differ dependent on who made it, some are bigger wheels in a T34 shell, the TT one uses its own compressor housing.

my silver escos pulled around 340bhp at 22psi, although it would hold the power for ages. 430-440bhp peaking 32psi

RickyLee53

Psi doesn't mean anything. A big turbo on 4psi will outflow a small turbo on 14psi. So it depends on your turbo/spec and how its mapped.

SiZT

I think it was more the fact that a T38 is a larger, more powerfull turbo than a GT28 and both would probably be using the same (standard bar springs) head

Oh and I'm sure someone has done over 400 on a standard bottom end

crazycage

well was a bit hammerd last night lol, it's not shit 330hp is fast by all means but there are much smaller turbo's that would do that power at that boost and have a bigger power band (t34 or gt28) would be my choice buget depending.

my gt28 maxxed out my 480cc injectors last year around 350hp and that was on 20psi.

p-s i have just clicked the link its not a t38 it says a t34 but on a ported head!! my head was standard bar the springs so i would still think it should be doing more for the boost.
