Thanks in advance!!

Hiya mate
Right 1.8zvh no point really u might as well go for a 2.1zvh with a efi head.
1.9 blocks are a 1.6 bored out, the cylinda wall is much thinner than a 1.6 so it wont last as long. if i was you i would get a efi head 1.6 steel bottomend cossie management running 250+ bhp

Unless they are made from the US block.

stevo

True, but i prefere 1.6

alridy thanks! I ment the US 1.9! not a bored 1.6

It's Czech Mate

All Steel 1.6 Bottom end and cossie management!

Why stick to the 1.6 CVH bottomend when you can use a Zetec bottom end which is stronger and has a larger capacity??

Doesn't make much sense to me but please try and convince me........


Grtz,
Mark

Hej Mark ook al hier ( dutch mode)

Marc, Just go for 2 litres ( if u can find it) or a 1.8 (Both Zetec bottom ofcourse)
Much stronger than cvh!! ( esspacialy if cvh isn't ballanced e.d)

Zetec crank can take up to 400 bhp, try that on a cvh

definatly go for the zvh option m8. get a 2.1 zetec bottom end, efi head and cossie management! 22psi..... 280bhp?

thats my next project

adamS2RST

hmmm...

slimwynn

would'nt it be best to go for a complete 2.0 zetec ????

Rick

Guest, mahle pistons are not forged. Zetec is NOT stonger. Im going out now, so cant relpy, but using the cvh head, 1.6 is far the best option for outright power. Ifu want more, its a totally reworked zetec (400+bhp)

gambit

its a personal choice but i like the american tall block

smitsturbo

go for the complete zetec turbo as its got the best bhp per pound it also can be tuned up to 500bhp if need be

SafeChav

I didn't think you could stretch a 1.6 block to 1.9

twinkle_2k86

thats what i thought as well its the extra stroke that makes it a 1.9, hence why they call it a tall block.
well thats what i always thought anyway.

SafeChav

Of course you can always bore a 1.6 out but i didn't think they could be reliably stretched to 1.9, and pistons have got to be expensive as fuck

twinkle_2k86

im sure the max you can go is 1.8 on it. altho whats the point then, as you say, custom pistons will be fooking expensive. Altho saying that, there was a couple of places doing the 1.8 turbo bottom end, im sure it was Power Engineering and Interpro, but this was going back a few yers now.

plus if you wanted to go 1.8 route, start of with the 1.8cvh out of the sierra.

SafeChav

I expect those bottom ends they sold were the 1.8 sierra bottom end, which is also a taller block from what i remember, and there alleged to be very poor

well i know that people running the power engineering 1.9 cvh engines ( called the system 2) with fith injectors were easily runnin between 240 and 250bhp. Also the ones running management were kicking 300+ and correct me if i am wrong but i dont know anyone who has blown a system 2 power engineering engine. Oh there was one i know of but he was running 315bhp and then put nos through it and admits to abusing the nos and that caused the engine failure. All the power engines came balanced hence them being so reliable and i know of people running em without a problem for years now (one has had for 7 years and another for 9). If the engine is built properly and using the right components trust me it can do you justice. Speak to ferriday engineering he has been doing this conversion for years and has not experienced engine failure due to components or block.

just out of interest, im in the progress of having my engine rebuild, its gonna be a 1600cvh +2 mm overbore(1690cc) ,but with a 88 stroke 1900 crankshaft giving 1858cc. steel rods,forged pistons,all balanced.
would this be able to run many miles when running about 260 bhp? or would the bores become oval in no time?

JamesS2RS

Ive just built a 2.1 zvh cossy man 300+ but for some reason i wish i had put the money into a 1.6 cvh i guess becuase it more of a task to get the power out of the little engine and 2.1 is an easy way of getting the bhp.

It's all down to what u want at the end of the day...

Cheers,

Jim

sas

I am curently running a power engineering system two bottom end at 28psi boost and 6750 rev limit.

gambit

wow!!!!!!!!!!!!!!!!!!!!!!!

S2Dan

1.9 American tall block, all steel bottom end, Cossie management and nice capable turbo, you will be laughing my friend, that is my suggestion

ivorbiggun

Got 2 1.9 yanks that can be bored to 84.5 giving 1987cc in basement. If interested PM me.

P.S.
PE's system 2 utilises cast (merc kompressor)pistons which are not
a very good idea.
