Problems with the f7r engine

ruf_ect · Jun 1, 2003

I cant start my engine after the F7R bottom conversion. I wantet the bigger clutch so I used the flywheel of the megane. Now I am wondering if the flywheel has has different triggerpionts of the egnition, since I only get a spark at the 2 and 3 sylinder.

please, enyone who has done this and know if I can use the megane flywheel???

have you put it back in teh car already?

take the sensor off, put the engine to TDC then count the triggers and location as they pass then compare to the clio flywheel.

No. Running 16v ECU for now. Everything is 16v, except for the bottom ink flywheel and clutch...

BenR · Jun 1, 2003

Not very helpful but form the looks of it (cant really see) the triggers look slightly diff, but teh angle is bad.

Actually, looking at it now, its been no help at all! hahahaha

sorry

ruf_ect · Jun 1, 2003

Thanks enyway Ben. Lookes like you have some cool software

!!!

I Read a post that you needed the Megane starter to do the conversion, so I asumed that people where using the Megane flywheel...

clean16v · Jun 1, 2003

yep, megane flywheel and starter needed, it comes ont he bottom end as a whole

viceroy · Jun 1, 2003

Ben isnt that the Renault parts software used at the dealers?

You need to use the megane starter cause the clio starter will not fit the megane flywheel.

So did people use the Megane flywheel??? Or do I have a different fault??

BenR · Jun 1, 2003

in most 2ltr conversions they use the 2ltr starter, but i dont know if they keep the F7P flywheel or not, but if it doenst work, that answeres your question dont it.

Viceroy.......no

clean16v · Jun 1, 2003

when i got a 2l bottom end, it was a whole bottom end, flywheel and starter attatched already

Adams_16v · Jun 1, 2003

mint, hope this one i just bought has the starter on it. almost bought one yesterday...

ruf_ect · Jun 1, 2003

If people use the megane starter, then they must use the flywheel. Good, then I dont have to take the engine out. But what the /%#¤#%&/( is wrong??? Ah, the joy of cars...

Adams_16v · Jun 1, 2003

Click to expand...

Nope

What about my brand new group N clutch i bought a few months back. Surely I can use the willy starter and keep my flywheel and clutch?

ruf_ect · Jun 1, 2003

Adams_16v: Dont think the willy starter will fit a 16v flywheel.

Red16: Booooost. Lookes good! Yes the flywheels are different regarding the clutch. But I am hoping the triggerpionts are the same. Would be great if you could take a detailed pic of a F7R Flywheel

Red16 · Jun 1, 2003

ruf-ect, a pic is no problem mate

williams starter will work on a clio 16v, as its exactly the same apart from the main body of it is smaller. bolt holes n everything are identical, honest!

Adams_16v · Jun 1, 2003

pheeew, ok cheers mate.

So this could be Rufs problem? if hes using the megane flywheel?

ruf_ect · Jun 1, 2003

I agree that the bolt holes are the same. If you look at the teeth of the two starters you will see the difference.

Adams_16v · Jun 1, 2003

oh..........sh*t...lol

need to find out then really...as id rather use my 16v one cos of the new clutch!

Red16 · Jun 1, 2003

teeth should be same on willy starte and 16v starter, cos ive used both starters on my flywheel and gearbox with no problems!

Adams_16v · Jun 1, 2003

actually jimbo was sayin he has a willy starter on his valver...

cliokongen · Jun 2, 2003

Hi!!!

Had the same problem doing a 1,8L / 2,1L swap

You can´t use the Megane flywheel as it won´t work with the 16v ecu.

It, only has 2 pick up point and will only ignite on 2 cylinders (lumpy idle!?!?

)

You have to use the 16v flywheel!!!

Regards Michael (DK)

Soon to post pics of my ongoing 2,1L big valve project

Chris_H · Jun 2, 2003

Michael is right, the joys of wasted spark ignition systems.

ruf_ect · Jun 2, 2003

Great info Michael!! Good to know what is wrong. Out with the engine again..

I have just bought a Williams ECU. Will this also apply when using the willy ecu. I mean: Are the 16 and willy flywheel the same???

cliokongen · Jun 2, 2003

By the way...

The 16v flywheel is a whole lot lighter... yummi!!

Get it lightened and balanced with your crank!! You´ll get a much smoother idle and a very rev happy engine.

Don´t worry about the clutch, it can easyly handle the power of the 2L lump.

But I think you will need a stronger clutch if you go above 175-180 bhp.

I can recommend a Sachs sporting / sintered metal. I will be superb for your drive round the Ring! But not funny in daily traffic! (I know, as my left leg is about doubble the size of my right leg!!! LOL

)

16v and Willy flywheel is exactly the same!!!!

And you can use the Willy ECU....

You got a CUP engine in your 16v?

cliokongen · Jun 2, 2003

Yep...

Cup engine.. It used to race in the danish Clio Cup, and won!! Bought it stripped down cause i needed an engine after I had a little accident with a 2,1L engine. I had a faulty inlet valve!! This F*****g valve sort of desided to leave my engine bay and this earth through my zorst!! Destroying the head and piston..

So had to do something, and bought the cup engine.. Cup engines are almost std. They had to conform to very strict rules. Small differences lie in fueling etc. Can post pics later as i have not used this fueling system on this engine but will on my 2,1L.

Pics at: http://www.hi-speed.dkwww.hi-speed.dk Go to gallery, and Michael´s Clio 16v

aaronc · Jun 2, 2003

What sort of times you getting? e.g. 0-60 0-100 etc......bhp?

Dust · Jun 2, 2003

Got Excited there, thought he actually had a 172 Cup engine in! Phew....

cliokongen · Jun 2, 2003

Dust: Have thought about that!!!! But haven´t got the time or money to do it

aaronc: About 140-145 bhp, but it is slow because of my 17" and the gearbox, which is from a Laguna. Too high final ratio
