At 350/370bhp standard internals are fine, up rated rs focus clutch kit and convert your car to hydro clutch to suit

Then you just need manifolds and turbo, management, job done

The oil pump in a mk1 frs always seems better than a rebuilt zetec turbo too, how many people have you heard say their oil pump failed on their frs?

If you are fitting rods and pistons then you might aswell aim for 400bhp

I,d use a cvh american tall block with liners to 1750cc,offset crank,steel rods pistons etc nms head and cam standard exhaust manifold modified inlet ,1000cc injectors gt30 and watch it rip the inner wings apart lol 400 hp

Sounds good to me! How hard is it to get the tall block now though?

Canada1

No need for liners of any type in the tall block - putting liners in a thin bore block will break through the water jacket. One now has a structurally weak block. these blocks were not designed for liners (as many aluminum blocks these days are).
The tall block is at 1870cc with 88mm stroke crankshaft.

The cvh head is a limiting factor for big power. First there is the air flow - which can be ported to flow more than a standard zetec. The second limitation is high rpm reliability.
pulled rocker studs etc..

You can certainly make a big power cvh ( I love these), you just need more boost because of cylinder head flow limitations and rev limitations. More boost typically means less ultimate reliability. I haven't seen anyone split a cvh block in two, or break a crankshaft yet - even at big power. The damage is usually piston failure, bearing failure or connecting rod failure - maybe oiling pump issues at extreme revs?

I've seen cvh blocks split from one side to the other

u goin to build your self another then mate

crazycage

so have I , project rs has split his in two. has been running 2.6bar for the last 3 years tho. his new engine has the potential for 1000hp not that we are going to spec to that tho but 600 is on the cards

rsmark86

Is he going zetec?

stuart collins

its alot better engine than a zetec mate

QplateRST!

Gunna be good put it that way!!

project rs

hopefully a 4g63 mated to a frs but as i only have certain tools at my disposal and the last person to do it said they'd not do it again ill have to wait and see if its possible to do in your own garage with a Ł1500 budget

heres whats been done to gearbox so far





once i'm a little further on i'll start a project thread on it and a big thank you to gary for all the nights were putting in as to even get to there has taken 3 gearboxs and several days as a lot of trial and error desiging a box to have all the bits inside it i wanted

James-W

I may have the lot for sale soon, focus rs engine, gearbox ecu etc.

rsmark86

project rs- very nice

crazycage

sorting the starter is the next problem, clutch flywheel and getting the box to bolt up are done

StephenC

Would love to go the Evo route I just know I haven't got the time to invest in doing it. Gary, did you get my PM?

I know of a k20 vtec turbo, full stroker ect going in a escort fwd, should be 600+bhp

Any pics ?

Never seen a tall block split they have better webbings and less core plugs, love to stu but just made the focus all steel no time for my new turbo and wastegate set up as its n day soon been concentrating on that pal prob c ya there .
ive got a s1 block on standard bore if anyone needs 1 , which would be stronger than the normal cvh as its thicker walled but they still split lol

Less.

Intresting thread and still nice to know, people are still building fastCVH's

rsmark86

iTrader: (3)

He's keeping under his hat untill it's all mounted and running, but don't look a lot to get it in with s1 roll bar and mount set up

russ rs

Mates got one in a 205 rapid but still like my cvh's

use to love the old daddy thrashes with tim, ollie, christian, stu and chicken in his xr2 all running

was very surprised by sean (turbobos) red frst. he use to gingerly pull off the line and then once moving he would nail it and still do 10 sec. to 100mph

That wont happen. I asked that very question to the new editor at Coombe mags simply cant get insurance to have those type of events now.

they got to do somethin to get the mag going as its been fairly poor since nick and dave went if u ask me

i agree

They better off attending rather than organising as there premiums prob the issue for public liability insurance

StephenC

who's good with zetec turbo engines these days then? Back in the day it would have been ian howell, is he still going? And next question is management and who to map, don't mind travelling for the right person. Would probably want management that can provide digital dash as well to tie everything together.

devil developments are rated well for zetec turbos at the moment

but for your target power just buy a frs tall block with box and clutch set up included, add a tubular manifold and gt28, injectors and ecu and you will see a solid 330bhp+ all day long

Indeed, simply can't be done from a magazine point of view anymore. Had it good for so long when it came to stuff like that but that format isn't feasible anymore. Unless someone else organises it and magazines will happily attend.

Devil Developments are the best Zetec turbo builders at the moment without a doubt IMO.

[quote=russ rs;6284148] yep

QplateRST!

All my latest stuff has come from devil developments or Crazycage if its manifolds I'd use Gary if its engine parts devils! I'm having my head done by devils

rsmark86

iTrader: (3)

Need to get a pf team together and attend ten of the best

I know the vauxhall boys still do it so could ask chip how the go about it

StephenC

yeah, think that's the route I'll go down, inlet and exhaust manifold from crazycage and let devil rebuild the engine and give it a few tweaks here and there to suit.
cheers

Don't think the fords are interested in TOTB any more which is a shame, for the past few years there have only been like 1 or 2 fords. There were quite a few at totb 1 2 and 3, but after that its been hardly any.
