F4R or F7R??

[16v_jon]

what would you be doing to the block?


well i dont fancy chucking in an engine with say 80000 miles that could be 95% track miles for all i know so i would get new bottom end bearing in and everything pressure tested. I'd also want the head checked over and probably ported and polished as well as the plenum chamber being sorted.

If you buy one from matt he will only sell you a low miler 20k or so, regards to modding the block would be an idea to get used to the power before doing anything to it, then rebuilding it over a winter

 

[16v_jon]

higher rated springs for the coilovers?

yes the 172 engine is a good 50kg more you would need a higher poundage spring the bolt spacing on 172 is 54mm your will most likley be 58mm

 

[Djw John]

It would get put in over the winter this year hopefully so dunno about running about as standard for a year, and then ripping it out again, know where your coming from though!

So would i just request the mk1 172 tb and ecu from matt then even if the engine was potentially from something else?

You could bodge the struts by drilling the bottom hole 1mm over diameter and using a set of camber correction bolts.

if you ran a mk2 172 cup engine (the easiest to convert) then you would need to change the whole dash phase 2 spec
low mile phase ones are hard to come by but you could have a phase 2 engine with phase one loom ecu uch and throttle body all the engines are the same some phase 1 (ph-quick) have larger exhaust ports but it hardly makes a difference est if you want a 182 manifold.

john - which power steering does your car have hydro or electric?

 

[Djw John]

hydro

I like the idea of ph2 engine and box with ph1 wiring, seems like the best bet for me

 

[16v_jon]

problems you will have and have to think about

1 power steering - your is hydro so it will be easy my conversion runs the electric rack (it took me weeks to get it to work)
2 fuel lines - as yours is a phase 1 it may have a return line if you run a phase 1 engine loom you may have to fit a pressure regulator
3 getting it started - the key has to be programmed to work with the ecu unless you can find a conversion kit with a key you will need your car programming when your finnished to start it.

The rest is easy everything fits where it should do

oh and if your going for a phase 2 engine try and get a phase 1 gearbox the ratios are slightly different and acceleration is much better

I think the best combination is Cup brakes setup (ie no ABS) so no MOT trouble register it as a Cup
Phase1 looms which are easir no UCH to deal with.
182 engine with phase 1 head.
182 gearbox (Ok slight issue here as there no abs but you could fix this by using a ABS looms to run the speedo
182 Suspension with different dampers etc.
All that in a white RS shell humm lovely. Just got to buy a house with a garage first.

 

[Djw John]

Ok thanks to you both for the help. plenty of food for though and no doubt will ask more questions soon!

Cheers again
John

 

[16v_jon]

how would you get the speedo to work with a phase 1 loom but no abs? and a 182 gearbox

 

[Djw John]

I dont have abs at the moment so maybe possible to adapt the wiring i currently have?

 

[16v_jon]

No abs you will need a phase 1 loom with the gearbox speedo sender and phase 1 gearbox , edde suggested the 182 box because of the diff retainer but you can convert the phase 1 gear bos with the 182's diff retainer (i did ) that will be the answer .
when you want to get started give me a shout if you need help with anything also matt is a goldmine of knowledge but your better off ringing him up at work as he gets paid for it then

 

[edde]

I'm sure it can be done use the 182 hubs or 172 full fat with the sensors and make the car with ABS as such but don't plug it in just use it as an output sensor. Or find out what the output from the gearbox sensor is and wire it to a ABS wheel sensor.

I'lk have a look tomorrow at the wiring if I get a chance.

 

[Djw John]

nice one thanks Jon, I qualify in October so the saving starts then, only 14 weeks to go, will be done over the winter!

Thanks again

 

[Djw John]

that'd be cool if you could edde cheers

 

[16v_jon]

for the speed sensor to work edde's way you would need the bosch abs computer to be plumbed into the loom the speed signal that come from the abs sensor are converted by the bosch abs computer to a signal the ecu can understand, you may be able to do it with some resistors etc

 

[Andy_J]

what about me, i have ABS already, is it near enough a straight swap if i use the Ph1 box?
