Hi guys, new to the forum.

Been looking about for a while for information on the CVH turbo engine and found some info. but need a bit more help if possible.

Have CVH turbo engine now installed in engine bay, but looking for info. on wiring the ECUs. I have the loom from the previous owner and also the original puma loom and ecu, but need to sort out the wiring to get the beast running.....

Has anyone done this conversion before? Heeeelllllp!...

Cheers guys - Baz.

ditch the MFi and go Efi. much easier! and more reilable!

1.9 xr2 on 40's

fuck off the mfi and get efi, loads easier, the loom with almost plug and play (both are engine looms and you can replug etc your into the cars)

everything else is frst tank and pump, managment from frst and turbo can be t3 with the rad is nudged, much better all round with efi
beware bleeding the clutch, any air will fuck the slave and its a sod to change again huh

Efi head
Efi flywheel and block adapting for CPS
Efi inlet
Efi ecu and loom
Map sensor and co pot
Charge carrier

check your block. if its a 89 onward, it will most likely have a CPS hole already.

hope this helps

barrymacpuma

is mfi that bad.

barrymacpuma

did any of the cvh engines come with power steering.

1.9 xr2 on 40's

its just sooooo much hassle

meterhead and all its crap ecu's etc and all those wires

an efi job can easily be done ina day and look factory
an mfi job will always look like a rats nest and have problems

you can do it many ways

i would always build up a zvh because even the cheap throw together ones are good on power and better than an old cvh

1.8 zetec bottom end with a cvh efi head + zvh kit
t3 turbo
frst managment
then the usual cooler, rad, pipe etc

all done for under 500 quid and you alreayd have teh box etc that will be fine

theres the same amount of work to fit wether its cvh or zvh but a little more work on a cheaper engine
you can still use all your oil feed etc from the mfi

barrymacpuma

thanks that put a spanner in the works

luke19790_3

you can use your head but you will need a adapter for the efi inlet.

barrymacpuma

too far into this project to go zvh maybe next time.
everything is in engine bay. layed out the same as the erst.
I got a running escort rst 90spec.
am hopen to use erst ecu.s wiren loom to run evary thing under bonnet.
puma ecu to run everything else
can you tel me if puma petrol tank. will fuel my mfi.
Cheers

MFI fuel delivery pressure is about 5bar, your intank pump on the Puma 3 bar, so no.

barrymacpuma

Thanks for that. but i was hopen to use puma tank with pump removed
and have erst fuel pump mounted where the fuel filter was.

1.9 xr2 on 40's

dude theres a fair bit going wrong here

i think you can use an escos or frst fuel pump being 'in-tank' pumps (frst pump housings have 'turbo' on a sticker on them)
an erst fuel pump pushes and doesnt suck so you cant mount it above the fuel level so i think puma fuel filters sit infront and above fuel tank/level

1.9 xr2 on 40's

my advise has to be sell the lot and start over im afraid

if you engine is 90 spec you will have a hole in the block going thru to the flywheel
which helps as you can fit an efi flywheel and cps (in the hole) and use your bottom end but by the time you do taht you will put about Ł50 into a headset and bolts that could have bought you a zetec bottom end then you will still need an efi head unless you want to spend about than the cost of an efi head on adapters (which could mean the inlet hits things)

barrymacpuma

dose any one no if 1.8 cvh engines came with power steering.
I was hopen to keep my puma with power steering.
a was thinking about a dry rack with corsa colum but lots of work.
ANY IDEAS

barrymacpuma

just got thread xr2 on 40s. i should have got a frst instead of erst.
my block has hole for tdcp. i am going to try sores every thing to efi
my engine.
this is my first convertion jumped in head first...
is my mfi head useable.
