anyone ever ran weber 45`s on the 172?????

[rsi_scotty]

iv got a pair of 45 webers and want to know if anyone has ran webers on the 172/182 lumps?? just curious really .i know everyone will say go with throttle bodies but i like the old skool webers.

cheers

You can run em yes but you'll need an ignition only management system still. I don't know of any Renaults running a carb'd F4R but there's a couple of Volvos I believe.

Will there be enough room to fit them?

I think if you removed the upper slam panel there wouldn't be any issue with space

 

[Fred@BTM]

plus fuel pump, 3.5bar into carbs won't really work LOL

 

[Dan]

Race tank + different fuel pump to match the carbs?

If its a road car it's sounds pretty pointless for the work involved, but so does 1000hp of supra on the road but people still do it lol

 

[rsi_scotty]

its not for a clio. its for an r5 gtt. i currently have a low mileage f4r lump which is being worked on at the moment. im looking into cams, i have a custom stainless mani made and the correct mounts to make the engine fit perfectly.i have a r 11 gearbox to make the gear ratio nice and short too so should sprint amzingly! l/b fly and helix clutch etc.

its just something i want to do. its no race car ,its just what i want.

so my idea of 45`s are just to keep it old skool and simple. they sound amzing! its either the 45`s or going to look into the rs2 inlet. which iv spoken to a few guys about.

so if anyone has any info or can help on the idea of 45`s on the f4r please post up! any help is great! opinions are fine too

cheers for the replys so far.

Why go from injection to carbs? A lot of cost and work for what gain?

not alot of cost really as i can get an inlet made for next to nothing and i already have a matched pair of webbers. plus its for love not bhp /power that everyone seems to aim at nowdays.

Just do it! But to balance them is a b**ch?? Is it like my motorbike ?

 

[rsi_scotty]

thats what i thought ! hahaha. i actually have 3 people who can tune webers local to me . and a local tuning company that deal with mk 1 mk 2 escorts lotus cortinas asta mk2 gte etc all ex race cars which run 45`s and the can balance em up easy so no worries there

 

[not normal dan]

Will you still be able retain the vvt system?

 

[Dan]

I understand the love

I think carbs can be done but there will be a lot of the "unknown area" to travel through to make them work well

 

[rsi_scotty]

im not sure about the vvt but should be fine. and as for the unknown area it should be pretty easy as i will be simplifiying the engine. but its a learning curve. so as said anyone thats knowledgeable ,any ifo will help .

 

[Dr HMS Derv Destroyer]

go for it, i like people being different. F4R carb'd = epic noise !

 

[clio ph1 Belgium]

I did build crazy expensive crap . Like my 750cc go kart haha. Had no differential , broke so many axle.
Had no silencers just a pipe . But it took me a while to balance the bodie's . And I gave it away for 0 euro's

 

[rsi_scotty]

like i say its more of a love build than bhp plus as said will be different!

 

[Dr HMS Derv Destroyer]

other thing is, LESS electrics to go wrong

Back in the summer a friend an I built a mk1 golf cabby with a 2 litre 16v ABF engine to run a twin 45 weber carbs, in standard form the abf makes 150bhp. After installing the carbs, balancing them an roughly setting the mixture with colourtune an setting the ignition timing it ran 207bhp on its first power run! We then fitted smaller mainjets which then reigned it back to 188bhp but smoothed the curve out nicely.

I think on the older cars especially it looks alot more period when carburettors are fitted, but if your after numbers an more efficient performance in my opinion theres much better ways of fuel managment.

I totally understand the OP's reason behind doing it all though as he is not particually after numbers an is doing it for the love!

 

[MicKPM]

Will you still be able retain the vvt system?

Should be able to yes but he'd need a management that can run VVC also. Fred has pointed out the main issue which would be the injection fuel pump which will need changing/fuel pressure stepping down for use with carbs.

 

[Dr HMS Derv Destroyer]

if you do this, i will have to come see it in person, wether you bring it FCS/CSS or some track day :approve:

thats fine . i have the subframe built with r11 box. once the engine is mounted i then have to make the choice!fueling is no issue either really as the r5 gtt has an inline fuel pump so will just get a new bosch pump and regulator. the hardest thing for me is electrics as im colourblind. and i have never played with management as all my cars have been old . the only new car iv owned was a masdaspeed rx8 which i used a company to tune.there a pain as standard!

so the main issue i see for me is wiring and management

I used to run 48's on my Escort rally car, fantastic!

Balancing, hosepipe is your friend, or an old stethoscope.

 

[Jack-C]

Fair play for doing something different, I'm looking forward to seeing how you get on with it.

Any reason why you don't want to stick with the c1j? A c1j on efi will make more power than an f4r and be just as reliable.
I know you said its not about power, I'm just curious. Carbs do sound awesome but so does turbo spool .

I remember someone putting an f4r in a R5 before and he said the extra weight ruined the handling and he want back to a c1j.

Hosepipe is the future when balancing carbs

 

[lewvr6]

Off topic I know..... but what gearbox code is your r11 gearbox out of interest? And presumably bell housing fits straight to f4r?

 

[Jack-C]

I think this is an f7r on itbs but it sounds amazing!

Well worth a watch

there have been a few fives built with the f4r. trouble is with efi on the c1j its expensive. custom inlet has to be made and there aint alot of people that will make em for you. the the major parts after soon add up. i got my f4r lump off a mate who got hit up the backside in his ph1 172 clio . the car had only covered 37000miles and he had owned it from new. i helped him break the car and i got the lumpfor 200 quid with box. had to be done! so this is where my idea began.
iv always fancied an older car with a modern engine. and iv always wanted to run a car with a set of webers. my dads had webers on his previous cars and have sounded the dogs danglys! so put it all together and this is what i want. the c1j pulls well and yea the spooling sound is great but theres nothing like raw na. when there going they scream.and as for the extra weight theres not that much difference. handling wise ,you just run harder springs upfront. again not really an issue as the five is only 820kg

What about itb's?

 

[rsi_scotty]

will check the code later mate . the box came out my old r11t track car. the f4r runs a 215mm fly but the gtt one bolts straight on so the 200mm fly fit inside the bellhousing and bolts straight to the block. also making an easy fit the the gtt subframe.

 

[rsi_scotty]

What about itb's?

find me a cheap enough set and i will do it. i havnt alot of pennys. so doing my best with what i have

 

[Jack-C]

thats f4r on bodies

Yeah I wasn't sure just saw williams in the lower grill and put two and two together.

Whatever lump it is it sounds brilliant!

Yeah efi certainly isn't a cheap option and in your position I can definatly see why you want to give the f4r a try.
Good luck with it, I'll be following your progress closely

Fair enough, I did see a set of jenveys up for sale in the classifieds section last week.

I take it you got the carbs already then?

yea there was a set for sale and they sold . everytime i find a set they sell. i cant afford new so will hold out for a second hand set. and yea i have a matched pair of 45`s.

Ahh I see, yeah would be interested in what the gearbox code is. Thanks for the info.

Be great to see an f4r on webers, something different, even if it's not typical route to go.

just went out in the garage and looked champ

r11 gearbox code -jb3 002

shorter final gear ratio than the gtt box.

 

[lewvr6]

Ok, thanks for that mate. Will be keeping an eye out for a weber'd f4r build thread!

hahaha gona need some help on it! easy bolting everything together but getting it wired up and running is gona be fun for me !
