I know its been asked to death but I want some advise on the best route to go with my engine. Basically my curent spec is;
Kent CVH35 and Vernier
Ported and polished head,
Stage 2 T3 with -31 Actuator
ERL MF2 5TH injector
Magnex and K&N
GRS front mount and GRS alloy rad
and its was 201 BHP @5600 RPM and 218LBS Tourque at 18.5PSI before I fitted the GRS front mount.

Basically I have no idea though of the engine history, how many miles the engine/parts have done etc, so want to freshen it up a little.

I saw lots of Escorts at Ford Fair running Cossie Management but I've heard its not all its cracked up to be? So whats the best route to go down?
1.6 CVH MFI
1.6 CVH EFI
1.6 CVH on Cossie Management
ZVH?
ZT?

I'd be looking for something with a reliable 250BHP for now probably and I think a full zetec turbo would be overkill for what I'd want. What would the best route to take bearing in mind I'd idealy want to cut cost a little and use my turbo as its got no play in the shaft etc.

Any advise appriciated

the key to power in cvh form is the head and cam so firstly who did the head and for 250 i'd go newman with solid lifters and go efi but which efi depends on who is going to tune it

Well I'd be keeping the engine thats in my car in the car and building up a totally seperate engine over time to put in. Just didnt know whether it was worth sticking with a trusty old 1.6 CHV with EFI or Cossie management with it or build a ZVH or Zetec Turbo.

for the power you've mentioned i'd stay cvh

Agree pretty much, but 250 ZT horsies are a fair bit cheaper that CVH??

I'd build Zetec T purely for future scope, building up a CVH past 280 odd hp is big cash. Once a ZT is at 250hp not masses needs doing to sail past 300...

I'd go ZT and build it properly, would be very smooth and not need much boost for 250bhp- plenty of future scope aswell then

C20LET would be ideal.

stick with cvh mate its the easyest was and the best! you can have 250bhp on a stock bottom end, as i have for about 8 months

standard bottom end
stage 3 big valve head
new man cam solid lifters
stage 3 t3
5th injector setup
front mount

worked pefect for me an was reliable, also went like fook lol

only getting rid now cause i want the 300 figure so going cozy managment

kit is on ebay

one of the main things i wanted to know was is cossie management all its cracked up to be? Is it worth doing?

I have done a lot of research into this subject, the main responce i have had is it depends on who yo have to tune it, tuners have ther own niches, eg stu @ motorsport developments and Karl @ norris motor sport can map cosie management in thei sleep to compete with the high end management systems. Jamie at Jamsport is the same with gotech etc etc. It all depends on how you want to go. As for your engine, bear in mind a few factors, with a full cvh it will be slightly if not will be stressed running 250 unless you spend some wonga on good steel/forged internals. a full zetec is the best for power/drivabilty but there isnt much room at all to work with in the engine bay. A zvh however gives you the piece of mind of being able to easily cope with the power and the engine bay will be nearly the same as the cvh to work on.

Speak to chris at www.powerconversions.co.uk he will give you some sound advice on the way for ward.

Hope this helps mate, sorry for the long post.lol

Theres no replacement for displacement.

2.0 Zetec Turbo

Cheap to tune to 250bhp, and leaves the door wide open for nuts power if you want to take it further, which inevitably you will because you'll soon get bored of 250 and want 350 etc etc etc. . . . . .

The biggest negative regarding cossie management is the people who do not run it, the most common argument regarding it is the age however they forget that you are sticking on a car of similar age.
I run cossie management simply because it give me the widest choice available with regards to who maps it, I can get Stu at MSD, Amhed, Karl Norris to map it and many others.
The fact that this system is sufficient enough to be used in Ducatti's, Ferrari's, Lancia as well as high powered cosworths prove to me that it will be sufficient enough for my CVH.
If Cossie management is not all its cracked up to be, the question remains why do the fastest escorts in the country still run this ?

If my car breaks down and requires a sensor, I have a good chance of obtaining a sensor from a local Ford Dealer or Cossie owner should this happen at a show, likewise there are specialists across the country with vast experience with this ECU.. its a production product rather than some niche specialist performance product

The other main complaint people make regarding cossie management is the price however the money I paid for my ECU a year ago is the same money they sell for still today, they do not depreciate in price.
I still do not believe I will be able to find an alternative ECU with the functionality that mine has for a lower price at this time.

Other than this im not a fan boy, the best advise you can ever hear is to find a mapper you trust and go with his recommendation, no matter how good the management is unless the mapper is capable of using its feature set effectively then the performance will be poor.

The biggest thing it changes however is the manner in which the car drives, it just feels so much more responsive that you can not explain until you have driven one.

1.6 CVH MFI --> Good when it works, but getting old and often unreliable.
1.6 CVH EFI ---> Good system but not many people can live map it
1.6 CVH Cossie Management ---> Great system with a lot of knowledge and experience behind it, reliable and well tested.
ZVH ---> Take of a decent flowing 16v head and do machining to enable fitment of a inferior 8v head (tuners love it, makes them lots of money)
ZT ---> A Great Engine, but takes big money to make the most of it. (I would not run your turbo on it) it would also need after market management to make the most from the engine

Copy Rst In Progress, his whole engine owes him about 2500 quid including the management and drives great so far.

He's going to Dave Walker for final mapping at end of september, not got steel rods so will have to keep the power a bit sensible, but should be great results as a nice useable but fairly quick road car none the less.

What does posting a thread regarding a very expensive, high budget and very high spec ZVH with specific pistons and management, along with purpose built inlet manifold, this is without mentioning the 6 speed gearbox offer to someone looking for 250BHP other than suggest if you have money to burn this is fun way to do it

I dare say you would not get much change from 4.5k (probably more) to get that engine to get it your car and mapped. Most peoples cars are not worth that much

The fact that Simon was running a 16v head which has been replaced by the 8v head puts him in a position to comment on the differences and with the same engine spec he stated "It feels about 75bhp down with all the rest of the engine, turbo and install been the same".
This simply suggests that the Zetec is a better head and cam setup as such to remove it and replace it with an item that is less capable seems a poor choice - Its ok if you are a business like Simon who has sold the 16v head to a customer and only went to ZVH because he had a spare 8v head..
Information such as this does not seem to suggest the ZVH is the better choice imho

Didn't mean it as a massively significant post, just some food for thought that 8v's get to that level....

Bit of PF cross ref. mate chill

Turbocabbie

I cant chill... I live with two women - ones a teenager and the others a nightmare Im surrounded by that time of the month

Ad4m RST

Flame away then mate...8v pinto pisses on a YB

im using rs2000 engine and management in my mk4, not as slow as you would think either! 7.68 0-60 at ford fair and quite good on fuel if money is an issue, i know you 99% going to stick with turbo but just thought id put my bit in that n/a isnt allways that bad

Ad4m RST

Galaxy bottom end and a T34

fonfe

have thought about it but if you look into how much is required to use the 2.3 bottom end its loads for not that great a benifit, turbo is a serious thought for the future though.
