I have decided on a 172/182 conversion for my 19 16v cabriolet. Questions...

[Reno5gtt]

After a long hard think I have decided to replace my 1.8 16v F7p with a 2.0 16v F4r lump.

Reason being I have set myself a 2k budget and I am going to struggle getting an F7r up to 200bhp with that amount. I have looked about on the net today and found all the bits to do the 172/182 conversion for around £1200, or even a complete 172 for the same amount.

Has anyone done this conversion, herd of it, or know anyone who has?

What problems will I have to overcome. Would anyone on the forum like to have a go at fitting it for a fee (i'd help) and take my old engine and box off my hands at the same time (free).

two main worries, speedo drive to my clocks and gear linkage?

Speedo drive will fit straight in on the early 172s iirc

Gear linkage will connect straight up as the 172/182 box is a JC5 which in most respects is interchangeable with a JB3.

Your biggest problem will be the exhaust manifold, you'll have to do some fabrication as the standard 172/182 manifold would be in the bulkhead if you put it in a 19. I have thought of using a supersprint 19 16V manifold, chopping off the head flange and getting an F4R shape flange watercut and welded on. Probably the most direct solution if it works.

 

[minichapperz]

did you mention the manifold would foul the bonnet/vent neal ?

 

[Neal R19]

Well I thought the inlet would but I've seen a 19 on youtube with an F4R in on standard manifold so clearly it doesnt.

that nakaphots or whatver, seems quick to me

Heres a f4r fitted and turboed,

its your best route to 200 bhp as no 172 actually put out 172 most struggle to put up mid 160's. Having test driven two 172 clios a really early one and a facelifted one i wasnt inpressed they dont feel that quick my 19 ([email protected]) feels as quick. maybe i just got two duds.

 

[Reno5gtt]

Your not the first person to mention about the exhaust manifold, I think that will be my biggest problem your right. Everything else seems pretty straight forward now, I have sent an Email to canems, for a price on engine management to directly plug the engine in with no cutting of wires etc... Also thinking of bike carbs again.

That was a good link there F2clio cheers, I have never been in a 172/182 lol I think I better go take a test drive first I just thought they'd be a bit more reliable plus being up on 40ish bhp they would be a better starting point to tune? Hmmmm

youde get a f7r over 200brake easy with 2K

engine like 200quid for a start

I offered him £200 for it a few days ago and he said he was just going to let the auction run because it is the only one on ebay which is fair enough... And I missed a 2L F7r bottom end that I bidded on that went for £40!! because I had to go out lol

Been looking on that williams head though Think Neal is sorting me out a loom for a 19 16v , didn't hear anything back from canems after sending an email. Might just end up chucking something simple to get my car on the track at french car show this year , you going?

Cheers

use www.gixen.com and set a price and walk away

willy head on a 1.8 is a wank idea IMO the inlet valves are bigger than the outlets so why get more in than you can get out?? LOL the 1.8 inlets are same size i use a 1.8 head and cams on my f7r and its quicker than a standard williams

 

[Neal R19]

Most/all performance engines have larger inlet valves than exhaust.

 

[bbracer16valver]

still seems a stupid idea

 

[BENZO 19 16V]

My willy lump coughs out some good torque an bhp, in my 19 if i remember it was 159bhp an 190ibs of torque,
just keep it simple an do what im doing stripping abit of weight out the car make it lighter .

The exhaust valve/inlet valve size comment just cracked me up.

Every engine has a smaller/fewer exhaust valve/s.

 

[Reno5gtt]

Canems have got back to me and they are very helpful, told them exactly what I want and they are sorting me a price as we speak for an engine loom to directly plug into my 19 but mate to a 172/182 engine. I'll let you know what they say, they did say it was a very simple conversion.

I have seen a few old side valves where the exhaust valve was the same size or bigger but these are generally pre war
