You're board arn't you?
Had abit of time Sunday morning so I dragged the 5 out the garage, mopped up all the water in the foot wells and got on with sorting a few issues.
First I finished the new breather system with a new filter but I'm considering modifying the tank so it has 2 ports for breather pipes and the filter on the top.
Second dropped the oil and filter and fitted new, so nice putting new golden oil in
What filters do others use on their non C1j engines? The standard part for that engine (in my case the F7R) or something else?
And third, chucked the bonnet on, cleared out the drivers seat and went for a rip
All seems good ready for mapping on Friday, 300bhp is my initial target for this year even though it could easy make more. Next year when I've saved up some funds ill look at a different gearbox, tubular manifold and inlet with twin injectors and then wind it right up
would just like to wish the oli, aka" the ipswich" the best of luck on friday for his third but not last mapping session of his ever evolving renault 5gt turbo, (im not the only one then) hope it all goes well , and if anyone else from the east end massive can make it, its 10am onwards @emeralds of watton
ps rumour has it oli's buying every one from the rtoc who turns up, a free breakfast stick!!!!
If you're still around at 12ish I'll stop off and you can buy me a breakfast stick for my lunch
Good luck on Friday Olli, and enjoy handy's stick.
WTF are you lot going on about?
Oli - bring the HP home tomorrow fella - hope it goes well, Sorry not to be there, I've burned my extra days already this year.
Good luck for tomorrow Oli, reckon first East Coast Massive meet up of the year is on the cards soon...
I think it might be something in the water andy, they're all a bit weird over that way
I'm working in kings Lynn tomorrow so won't be able to stop in now, bit gutted as I wanted to have a nosey round the toaster as still not seen it converted yet
Try not to blow it up, you've got another engine to pay for
Hmmm... engine for project 'old codger'...?! C1J
what a day!!
i will leave oli to post up results, but it now seems gearboxes are his next purchase/upgrade dont think it will happen ready for national day, but you never know
dont think he got time to enjoy it before it stripped third gear by the sounds of it
we all knew it was the weak link ,but expected it to hold out longer than than a mapping session and a drive home less than 30 minutes away, on a plus note he has seen both mine and jp's 02m conversions go together, so at least he has a head start and will find things quicker to source

So come on don't keep us waiting then what power did it make did it make the 300 you was hoping for or did it make a lot more
The day started ok, left my place at 8am, it's a 30 minute drive to emerald, I needed to be there by 9, I wanted to be there early. Within 10 minutes of leaving home I'm sopped at a garage with a failed TPS sensor, whilst waiting for a tow I decided to check the fuel filter wasn't blocked, almost wish I hadn't as I found yet another bodged job by the guy I trusted to do the original efi conversion.
Fuel filter the wrong way round and held in place with a tie wrap, fuel hose to tank looked like carb hose not injection hose and the pump itself looks smaller than the Bosch 044 it's supposed to be.
Not too much longer Mal turned up and towed me to emerald where young Jono and HAndy got the TPS changed aswell as fit the larger 560cc injectors, Jono started mapping at around 12 and straight the first numbers were good, 238bhp at 7psi, not too long after that 257bhp at 8psi, a couple more hours of part throttle mapping and is was time to start upping the boost.
And again we hit problems, at 10psi it misfired massively, we swapped out the plugs for some new ones HAndy gapped abit tighter and fitted a temp fuel pressure gauge to make sure the pump wasn't playing up, the plugs made the difference and we got 14psi where it made 284bhp and 281ft lb.
The fuel pressure did seem to move around a lot which concerns me abit so I'm gunna rip out the pump and filter and redo the system properly.
We would of turned the boost up further but the solenoid was maxed out :/ the actuator would take it but the solenoid wouldn't so we ended the day there.
Unfortunately on the way home it popped out of 3rd gear and wouldn't go back in, before hand it was going like a stabbed rat. I didn't a chance to give the gearbox a once over when I got home as the misses bundled me into the car for a weekend away for my birthday.
I can take 4 things from today.
1. My charge temp problems are gone, didn't see over 28 degrees all day.
2. The fuel system needs a complete over hall.
3. I'm pretty sure the stock megane cams arn't helping flow and are costing me power.
4. The cast exhaust manifold although restrictive and poorly flowed did its job ok and with time should still produce the power I want for this year.
bugger mate! it looks like it's just plain luck (or unluck) with these gearboxes. one drives with 300+ lb/ft without breaking it and others break it within a few miles with less than that.
i hope you fix it soon and finaly have the chance of enjoying all your hard work!
Oli - FPR have you got on there?
would still look into trying to get a smoother curve on the boost, maybe doubling up on the solinoid valves as the cheaper option, as your system is already linked into the ecu
Just took her out to see if I can figure out what's wrong with the gearbox and it worked perfectly
So I gave it a boot full at 14psi
Well done Ipswich! Is the blower fairly laggy, looks like u gotta use the revs to get it going but when it's spinning looks like it does a top job :-)
Not as bad as you'd think, knock it down a cog and your off
Makes plenty of power on low boost but its deffinatly being choked top end when the boost is turned up, the manifold doesn't help but the cams are the first thing to change as I'm sure the engine will flow much better with better cams
Well I've done nothing to the 5 except drive it, till tonight....... Boom the diff went a mile from home
that's not good mate I've got a spare box if needed
It'd probably work lol
It's the diff that seems to be the week point, more specifically the crown wheel comes loose from the diff itself.
I'm in the process of stripping it down now, just the driveshafts, down pipe and gear linkage and she'll be ready to come out.
Been thinking about it more, it's either the diff crown wheel or I've stripped the splines off the centre of the clutch friction plate :/
If its the diff ill chuck a Gtt box in for now, if its the clutch ill have to wait a couple of weeks for funds
Got most of the car stripped down by lunch time, just gotta pull the engine and box out as soon as Butterbean finishes with my engine hoist but I was able to find what failed
Bearing in mind the circlip had been welded to stop it popping out :/
So while everything was out and the car up in the air I got the wishbones braced al la turbo ted stylee
The plates are bolted for now but when I'm getting Mal to do the tracking and camber setup and ill get him to mig along the edges of the plates to strengthen them further

i used a plate which comes on newer Renault jc5 gearboxes to reinforce the diff:
made the holes a bit bigger so i could fit 12.9 m8 allen key bolts
sorry mate, i don't.
i got it off someone who wasn't going to use it himself. however iirc it came on al newer jc5 gearboxes so if you could find someone who has dialogys he could find out.
or just visit a nearby Renault dealership and ask them if they could have a peek.
as you can see in the pictures i had to file the outer edge because the radius of the plate fouled that edge.
good luck mate!
This could be the cheaper option for those happy with say 300 - 350 bhp, what about putting an LSD in there Oli. I know it's £££, but if this is the part needed, it will be a lot less than the OM2 route plus a huge performance enhancing upgrade.
