What would my 2 litre Zetec turbo go like on this turbo.
Would spool up real quick but what would the max pressure be till 6500 rpm.
Looking for about 300 bhp with a big powerband.
Engine made 262 bhp and 395 nm on about 1.1 bar with a cosworth t3 @ 4700 rpm ( needs better setting up ).
Standard silvertop head ( stil looking for a frs or st head ) cr 8:1, tubular exh. and rover inlet, fmic.

Thanks

will be good.should do exactly what you want of it.

This turbo is good for around 350 bhp.

You could use it with a 0.48 exhaust housing to make it spool sooner.

I think there is a gt2860r that is good for 310 bhp, possibly the smallest size of gt roller bearing series.

would be ok for what you want but not with the .48 housing on this type of turbo .64 is the smaller one and up to .86 is the one for making the big power out of it .48 is cossie turbo's totally different to the gt turbo's

just use a pulsar turbo same spec but wet bearing run's the .86 turbine aswell .the comp wheel's on the gt28 and pulsar are the same as the cossy 4x4.just something to think about

1.5bar...
.86 turbine housing..

Gregor

Sounds good

.64 is the smaller one indeed and the one i was looking for.


Should do the power but then i loose the big advantage of the roller bearing quicker spool up?!?

Gregor

Well. got myself a gt2871r instead kind of cheapisch so that should go good...:P

project rs

the 2871 is great on zetec turbo's but if your still on standard head cap your boost for now at 12psi or you'll get valve lift and what size you got .64 or .86 the smaller one is good for 1.2 bar after that it's just hot air

crazycage

as project rs said whats the spec of the gt2871 theres about 10 different ones lol

It's this one with .64 turbine.

Head has been worked on a little and has hd Springs bought from ian howel... should be good for 21 psi @ 7000 rmp so i've been told

crazycage

thats a little smaller than the one i run ,you wont be able to run much more than 1.2bar on the 0.64. but on a blacktop you will still see about 280-300hp at that boost on a standard head with uprated valve springs and a good inlet.

p-s it will boost very early and easy pull you past 6500rpm that you want .

Gregor

Hmzzz, was planing on about 1,5 bar but we'll see how it goes.
I've got a silvertop head wich i worked on a little myself with uprated springs and a rover inlet.

project rs

you will get your 1.5 bar but you will find yourself pulling ignition out to overcome det at those levels and watch you don't damage something really you'll need a egt hooked up to as they climb really quickly over 1 bar on that turbo

Gregor

Hmzz to bad then, might just stay on 1.3 orso.. we'll see how it goes.
Main thin is to get a big powerband and arround 300 bhp

EGT is on the wish list....

thanks sofar

project rs

stick to 1.1-1.2 bar and trust me the powerband is amazing almost no lag and hits you like a train in every gear straight to the limiter or it does in our little fiesta and if your on motorway no need to go down a gear simply put your foot down in 5th and it's off

Gregor

sounds good to me
