F4R or F7R??

Just at the plotting stage but what 1 is the better vfm engine to fit in the mk2?

Has anyone put a F7R in a mk2? I reckon it would probably just be my brakes that id need to uprate as my suspension has been done whereas everything needs done for the f4r.

Any opnions are more than welcome!

erm i thought it was t he f4r Matt sold for £1500 plus vat (172 engine yeah?)

Whereas a f7r can be had for less than a third of that

F7r edde?

its not a case of buying an engine and sticking it in the mk2 clio works on a multiplexed wiring system it would be much harder to fit an F7 engine than it would a F4R

how hard to do an f4r from a k4m?

thats my plans and it dont look difficult mechanically, 16v jon, u sound like u know your electronics.. could i use the same loom and change the ecu out?
 
Ooops yep sorry mixing my codes up

I meant 172 engine the F4R is the better idea.
The F7R could be made to wrk though the easy way would be to swop the whole looms from a crashed Williams etc I'd think.

u say could be made to work, with the same loom as the 1.4s and/or the 1.6 16v?

Might as well swop the looms as well a f4R is say £500 then £300 for a box £150 for the radiator etc then you need the driveshafts and brakes and supension realy so that say £300 for an extra £400 you can have the whole loom for an extra £200 or so.
The ECU's are the same so in theory the stock one can be rempaped to run the F4R engine its not worht the hastle though.

Andy I reckon it would need to be a combination of looms but this is done on things like vauxhalls so no reason why it couldnt be on Renos.

Yeah but would I then need to swap things like my speedo and other instruments?
Not a huge job extra realy when you think you've talking about swopping the engine gearbox suspension brakes radiaotor etc anyway.

Yeah but when the dials are a completly different shape thwn it would look s**t!

Swapping mechanical bits is more interesting anyway!

mmmm

right well then f4r is more likely. Mines is a ph1 so a mk1 172 engine would seem the more natural choice but these are getting on a bit now. Wouldnt mind a 182 engine but with teh cable throttle!

Would'nt say the 7 will be cheap mate. Matt wanted alot for just an engine when i converted my hybrid and i didnt find a cheaper low miled one elsewhere, just decided to go through another party as it was close to home.

I would say a good engine will cost between 6-800 and a good willy box will be anything between 2-350 and then the fitting will probably be a b**ch in a mk2.

Id just do the 172 engine which should be easily findable, abit more power there for the heavier mk2 shell too.

The engine would fit there the same engine realy. Just need the Mk1 throttle body.
How about a rebuilt 172 Mk1 engine and have it fettled and tunned when its being rebuilt?

mmm good point jay

Day yeah that was the original plan but im a sentimental fool who doesnt want to sell his car! It would make financial sense but hey ho, im only young once!

Yeah could get a rebuild with headwork and get a 182 manifold on at the same time i guess. labour charges would hopefully be kept to just the rebuild, got a good bunch of mates and between us we could chuck it in i reckon. Gonna see where is cheaper than Matt!

ooo a conversion happening john?

just something I'd like to know....how do insurance companys look at this, eg is it cheap to insure a 172 or a lower model with a 172 engine (modded)

Depends on the compnay one way round it is to get the looms engine etc from a Cup etc and get your car reregistered as a rebuilt Cup and you xcna insure it then as a normal Cup etc but has been a Catagory rebuild.

Yeah you can re-register it with the dvla apparently. I'll be nearly 24 by the time its done so insurance shouldnt be too hefty hopefully. Will be a lower ,mileage policy as it would become my fun car with a diesel or lpg runabout for commuting

most likely!

It'll probably stay how it is for a while after getting the engine done and then we'll see about other things. But it would be fun to have a track car!
 
  Tweaked Leon Cupra R
Thats what ma clio is aimed towards, a designated track car!

Me and ma brother are gonna do the swap..

can u run the 1.6 shafts wi a 2.0? or is that asking for trouble?

or can i run 172 shafts wi 1.6 bearings?

i reckon you wouyld be best running the 2.0 shafts as they are intended for teh box and hubs so you may as well.
You could sell on a compltete 1.6 16v i bet
 
  Tweaked Leon Cupra R
i dont wanna chage hubs, got ma fk's on and not sure they are the same fitment as the 172..

mm the 172 hubs are different and the shafts only fit them i beleive. Remember the track is wider too. You'd maybe have to sell the coilies on and get new 172 ones

the 1.6 shafts wont fit into the 172 gearbox or hubs

you need to change the engine gearbox engine loom uch ecu decoder ring shafts front brakes, hubs and suspension internal wiring loom clocks fuel pump radiator hoses front brake hoses

matt supplies the whole kit for £1500+ vat the reason for this is he includes everything and if your missing somthing or its broke he'll send you a new one you can buy kit cheaper but they wont supply you with things like the vin number so you can have a key made etc,
I even had 2 gearboxes from matts for free when they shouldnt have done and they are always helping me out with diagnostics for cheap.

The conversion can be done cheap but only if you do the labour yourself, if not then your much better off selling up and buying a mk1 172 or even a CAT D repaired MK2 as the labour charges etc will be murder

So you reckon its best to stick with matt then cos of teh service?

How much is rebuild likely to be, dont want to put it in and blow it up too quickly!

As i say the labour would be free apart from the engineering work on the block itself

The track is wider due to the hubs the wishbones and drive shafts are the same lenth

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.
