F4r/f7r

Does anyone have any cross section pics of these? I need to know where the oil and water galleries are on each.

 

[BenR]

erm.........look at the oil and water gallery's?

 

[Dan@SJM]

i would but i dont have either engine apart!

 

[Dan@SJM]

Right well ive just looked at pictures and the oil returb is on the other side of the block on the 4R, so i am going to get the 172 head machined for a dizzy, then run the williams managment, and scrap the vvt. either that or...

Does the 172 managment Need the uch to run? or can i strip down the 172 loom and cut out the bits i dont need, i.e the uch, and just have the engine ecu to run the engine, i know ive got to tackle the immobiliser, but thats not a problem, but the uch does concern me.

 

[BenR]

Why the willy ECU? whats the point, run the 172 ecu.

You'll have issues getting the correct distribution off of correct cam since the inlet has VVT on it, and the ex doesnt have the correct alignment for the rear slot, although i have tried and it does fit with very minor work.

 

[Dan@SJM]

yea, i was planning to do it in a weekend or so get the 172 lump in and running.

I will go down the route of using the 172 ecu, just need clarification of the uch being needed for the engine or not.

 

[BenR]

you dont need it if your not running the 172 dash, you can just use the ECU to run the engine.

Depend if you using the phase 1 or two the phase 2 needs the UCH. Idealy stip your loom down.

 

[Dan@SJM]

brilliant, im using the ph1 loom, so its all gravy.

I thought you had throttle bodies and a webcon ecu?.....at least thats what u told me.

 

[BenR]

lol............here we go again?

 

[Fred@BTM]

or why not buy a turbo F4R head off me (no vvt) whack a megane RS mani and turbo on it and off you go

 

[alexbleubolt]

whats a uch

 

[Fred@BTM]

the brain of the car sort of

 

[alexbleubolt]

the brain of the car sort of

thought that was the ecu, but dunno what a uch is, and like to expand my knowledge of these techy terms, whats it stand for universal control head ?

 

[Fred@BTM]

the ecu is the main brain, its kinda like a secondary unit

 

[Dan@SJM]

So many differnt directions i want to go, but as you said i cant get the ecu maped other than by a webber dealer i gave it back to the guy who got it for me.

 

[alexbleubolt]

thanks

Money, plus ive got everything here i need!

 

[Fred@BTM]

i never said i wanted much for one

 

[stan*]

maybe just oral?

 

[edde]

whats a uch

Its the computer which runs the car realy its the network which runs everyhting realy on tyhe phase 2's the ECU only runs the engine.
