If going for cosworth turbo, don't go with cutback blades

wedge07

How come?

rsmark86

iTrader: (3)

ive seen threads showing back to back tests on a t34 and clearly slowed down response and increased lag, but in fairness it did pull harder at top end, but on a 1600cvh you still want the response

wedge07

Do you mean don't get cut back blades on a t34 or cossie t3 or both? That description I put on before is already done and ready, I just need to click buy cr turbos want 600 odd which I can't afford, should be able to just about get 400 lol

i would say dont get it, but if its a very good price and a very good spec and condition then i would make go for it, that would be a 300bhp turbo aslong as you have a worked head and decent cam set up and maybe a decent inlet

zvh

my 2.1 zvh run a stage 3 turbo technics t3 with 2wd cossie compressor wheel and 48 back housing made 286bhp @21 psi on rollers runing at the time with mfi and a fith injector set up i may add it lasted 12 months at 1.5 bar before turbo seals went

Been told to go standard 4x4 cosworth Turbo with a 360 thrust bearing ...any opinions ? ..i want a reliable 260-300 .

stwibs

Similar spec to mine but I am contemplating switching to a standard cam profile...i have messed about with the cam timing which made things a bit better but still turbo doesn't come on till a bit late.

Rsmat

What's similar spec mate ? As mines been specced to come on boost from 3300 to the limiter with my spec dialled in and mapped .

stwibs

I'm on standard rockers and springs with megasquirt.ported head bigger valves it just seems to come in a bit lazy..then seems to shoot up the revs from 4k ish

Rsmat

iTrader: (2)

Im also dizzy less I'm on coil pack ..im on standard valves also as my aim was 300 max ...seems strange mate what Turbo are you running ?

stwibs

4x4 cosworth...is yours up and running yet ?

Rsmat

iTrader: (2)

Same turbo as I'm going for ...no as I'm only inns stage 2 T3 at min mate .

You don't mention manifolds but decent inlet and exhaust manifolds will see faster spool up times, lower running temps and the same power at lower boost levels than if you were using standard ones.
A reliable 300bhp is not a phrase you can really associate with a CVH... At that power cracking blocks is very very common and cam failures (Yes, even with Newmans).

Rsmat

It's having a Crazycage exhaust manifold and inlet is a modded s1 inlet .

I think 270 is going to be more realistic .

In this day and age you should be running something like a GTX2860 and not an ancient T3.

I've a Brand new BW 6258 on the shelf but been told have to rev the engine hard to get it to work right .

i was thinking about one of them for my 2.1 zetec turbo matt.is it just a problem with the 1.6 cvh or is it a fault in the turbos them selves?

im only after 300/350 bhp

rs.head

Just sold my golf that had a gtx2860, was an awesome turbo, and simply my favourite set up

Jay,

iTrader: (4)

James a 6258 will work on a cvh but your right the cvh isn't worth the money as a zetec will do so much better with half the money thrown at it

rs.head

Yep
Rods, Pistons, frs gasket and bolts, dd valve springs and you got an engine that will be ok upto around 350/400bhp

Then it’s just cams and head work after that

Rsmat

iTrader: (2)

The 6258 works Great on a Zetec and not so well on a CVH as ive learnt .. if it's the power of 300/350 then the Zetec is a no brainer ..i bought a forged Zetec with all the right bits for 550 and theñ decided I wasn't going to cut and weld a bracket on the inner wing of the mint shell so opted to spunk a lot of money of getting a cvh forged etc ..youre xr3i/turbo on the other hand that would be having a Zetec if It was mine ..there a fantastic engine once tuebod

rs.head

Yeh I had a zetec turbo frst before and was rapid

I’m going to get mine mapped as is, then start saving for a zt, I already have a mtx box in the garage to use
