Bumblebee 2 featuring LY R26

[Brigsy]

Going back to post above i wasnt happy with the compbrake top mounts as the small spacers were missing. Looked at all options and oem are pretty expensive and no camber adjustment. To fix current ones spacers and bearings around £100 from compbrake. As i love destroying my bank balance i looked at the PMS meg2 top mounts and went that route.

Ordered and arrived next day. Sexy


The engineering is superb. One of the best aftermarket top mounts ive ever seen. Leagues ahead of compbrake, bc, and the ast ones i have on the kangoo.

Main reason i went for these is they do not raise the rideheight as designed not to.

PMS vs oem.


Compbrake in comparison add 10-15mm to rideheight which is sub standard on oem shocks/lowered springs..ok with coilovers maybe.

As with all pms products it fits exactly how it should.



Set negative camber as much as available on standard diameter springs as they hit the turret if you go for more. Its -2deg so thats fine for what i need.

Fitted and back on its wheels. Taxed and on the road.




Straight down for geo and dialled in 10 mins of toe overall. Camber -2 deg as above and castor is around 5.4. Thrust angle is now zero.

Looks much better with everything new!




Now drives excellent. No knocks or nothing, as straight as a die. Turn in is awesome, and its absolutely planted on the back roads like a good r26 should be!

Also improved the overall cabin rattles and creaks as ive adjusted the boot latch to pull boot closed tighter. The boot used to creak when going over bumps etc, and now no noise with it adjusted. Done the same to the blue meg years ago and its like night and day.

Took it out for some datalogging on the evening. Started raining so didnt go too mad.

Noted coolant temps when cruising are slightly higher than expected between 90-92deg. In comparison megs are usually in the 80s unless your driving quick.

The bumper under tray is missing so airflow is not forced through the rad pack so id say thats the issue. Done the same on the trophy and refitted it and dropped a few degrees off temps. Ill bang a new thermostat in just incase.

Washed the bird s**t off it on Sunday and it rained as expected.




Progress has been a little slower than expected but were back road legal and only a few jobs left. Get the snagging finished and get a trackday done soon hopefully!

Thanks for reading.

slower than expected, mate you smashed getting this back into tip top condition

Yeah I was gonna say, time like this for car stuff is what dreams are made of!

 

[Brigsy]

Cheers all. I reckon i could have had it done 2 weeks ago if id had foresighted the top mount issue.

It pained me taking it apart again but it worked out miles better in the end. Drives fantastic for a megane now.

Ive been away with work this week and the mrs has been using the meg daily. Said it drives awesome and its not broken down so id say its a job well done!

Drivers side window has packed in however, well it is a fcuking renault aint it so something had spoil it :LOL:

Used it lastnight.



Noted headlamps are pretty crap even though xenon and the lenses have been polished.

The lighting ecu was wrecked so the self levelling does not work on the xenons. Id sniped one off a breaker to fit. Bumper off in 2 mins, headlamp out and fitted


Headlamps still not doing the level setting when turned on. Hooked up clip and ecu still not recognised.

Dug out the workshop manual for diagnostics.


Connectors were good. Time to check fuses and its the upc one. Right piss on taking battery out etc.


The 7.5amp fuse was indeed popped. Not suprised considering the state of the xenon ecu. I actually think its dragged on the floor at some point.




Put it all back together. Does it work? Does it fcuk so that was pretty fruitless.

The headlamps work ok and ive adjusted the level on the drivers one manually as it was pointing at the floor. Had same issue on blue one years ago when lowered had to wind lamp adjustment manually to max. The xenons work right on the blue one however iam suspicious of the level sensors on that as both bars popped off years ago and made no difference to the lights!!

The headlamps still work ok so i might revisit one day when really bored and start pinning the wiring. Until then it can wait!!

Updates

His and Hers together. Blue one had a quick clean before its mot last Tuesday.






Check out the camber on pms top mounts on the yellow meg vs stock top mounts on the blue meg.


Give the carpet a wet vac and fitted some nice oem r26 mats that ive had in stock from breaking the red r26 years ago. Give the steering wheel a quick rub over with some ipa that removed years of grot and took it back to a matt finish. The red band stitching is knacked, looped some electricians tape round it to take your eye off it.


Changed sidelights for osram led ones to replace the piss yellow standard ones.



Been having a bit of fun in it on the commute too.

Noted that the heater blower was not very blowy. Cabin filter was on the list to change.

Nice.



Hoovered out and new filter fitted. Blower is a bit more blowy.

Thanks for reading!!

I think I prefer yours over the missus' car

 

[Big Steve - Raider]

Loving the Blowy updates!! Keep it up @Brigsy

Blue one is the OG overall its absolutely mint in comparison. Mot tester even commented on how good it is and he hates renaults! Yellow one is an eyecatching colour though and it drives great for the money.

I love how you give this lemon your TLC to bring it back to life.
Your has all those things all megane 2rs suffer from.
M2rs is by far my favorite renault sport car, i love working on them en preserve some for the future.
Thanks for keeping us updated, i really enjoy reading this topic

Where did you get the new front shockers from @Brigsy?...I was led to believe they were NLA?

Thanks Sir, glad you are enjoying the updates m2rs is also my fav renaultsport.

I got the front shocks from RPD. Still in stock iirc.

Renault Megane 225 R26 Front Shock Absorber - 8200647895

Renault Megane 225 R26 Front Shock Absorber - Renault Parts Direct - Renault Parts Direct is a web based service from our authorised Renault dealer.

Rears are NLA as far as i know. I could do with replacing them at some point but have tested mine and still in working order for now. Mk3 rs shocks fit the rear so they are an option.

 

[GazTwo]

Thanks @Brigsy I've confused myself with all my shocker requests from Paul! Paul did manage to secure me some rears not so long ago, I'll get some fronts ordered for stock, I'm hearing NLA far too often these days

 

[GazTwo]

Optimiz is showing stock of rears @Brigsy, I'm also waiting to see if he gets any R26.R shockers back in stock.... Chassis

 

[Brigsy]

Spot on ill have a look, let me know how you get on.

Loads of bits will be NLA soon on the meg2 sadly. Get the oem bits whilst you can.

Updates

Down to 1 tealight candle instead of 2



Ballast and new bulbs on order. The headlamps are terrible! Might just go back to halogens soon.

Whipped bumper off in dinner hour today to sort light issue out, first day its not been raining and actually had time. Annoyingly passenger dipped headlamp which had totally failed was working again which made diagnostics tricky.

Fitted new 6000k D1S bulbs and a new ballast to passenger headlamp, quick test and working.

Had a look at the lighting ecu wiring whilst in the area, i fitted the 2nd hand ecu a while ago but had no comms with it on clip and not working so left it. Peeled loom tape back a little and found the issue straight away, snapped canbus wire.


Wiring was pretty corroded so chopped it back a bit and spliced a new bit in.

Dual wall heatshrink to finish.



Headlamps on and noted motors moving with ign on.



Hooked up clip and no multiplex issues anymore. Lighting ecu available for diagnostics.


Faults stored as expected so had a look in, old ones from previous car it was fitted to.


Cleared the old variable pas fault that was stored and first time its had a clean slate.


After clearing the old stored but not active multiplex fault on the pas ecu the cruise/speed limiter works again. Not 100% sure that this fixed it or coincidence, had tried a spare switch in previously but no joy so guess something had happened.


Much brighter now. Id say thats a win.

 

[Brigsy]

Macro run today.




Stripped out rear is perfect for the chicken, crisps and sweets run :LOL:


Still getting the odd whiff of oil looks to be leaking slightly on the turbo oil return gasket or top part of the oil return where it had the chemi metal bodge. Had it on my mates lift looking earlier and cant see hardly anything just a slight bit of oil on the joint. Its not even leaving a drip of oil. Ill prob whip turbo off to inspect as will be easiest option.

Borescoped the turbine wheel through lambda hole and dry as a bone. Slight damage to the turbine wheel possibly this was on the engine that blew up previously. Boosts ok to be fair.


ill sort it soon.

Done a bit more today.

Bumper undertray was missing which was not helping with airflow to the rad pack. Expensive as fcuk to buy new for a flat bit of plastic and unobtanium 2nd hand unless buying a full bumper.

I bought a povo spec megane bumper undertray which was no where near when offered up so that was a waste of time. I have a couple of ph1 225 front bumpers in the lockup and thought it was worth a look to see if ph1 undertray could be modified to fit.

Turns out, ph2 uses the exact same undertray and it fits perfectly even though the bumper design is slightly different between ph1 and ph2.

Small bit of original left in place


Offered up against ph1, identical. Test fit and goes straight on.


Originally rivited on, used rivnuts instead as have them in stock


Fitted. Centre bolt on front subframe was snapped so had to drill it out and tap it.



Daft hour to do that so moved onto next job, fuel pump. Bought a bosch pump from autodoc, same one i use in the blue meg at 300hp so adequate for this. Easy job as no back seats in. Sender was covered in s**t and looked like original and took half a tin of brake cleaner to get the crap off the top. Actually looked fairly clean when removed so dury out if changed or not. The bosch pump was slightly diff from the original pump when removed which had no branding on it but fitted OK so sent it.


s**t in the strainer as expected


Back together, fired straight up when primed and seemed to idle a little smoother, unsure if placebo or not but revs as normal.

With any fuel system repairs or mods - afr check should be done just incase something has changed, saves melting a piston or 3.

Dug the oldskool innovate lm1 wideband and sniffer clamp. Still a great bit of kit had it around 15 years and tuned many a gtt on it.



Datalogged the ecu parameters with Rstuner. Full throttle/boost afr 11.8 which is spot on so no problems with new pump.



Coolant temps are a little more stable with bumper undertray fitted, however on a good full throttle pull you can see around 100deg which is too high for my liking. Its fine when driving normally though. Temp gauge never moves off the mark as per any renault of this era, i assume itll need to be 105deg+ to see it shift up a notch.

Its currently got the old aftermarket megane 2 valeo rad off the Kangoo fitted which is not the best for cooling as its not got as many bars as the original rads. Ive got an oem renault rad to fit and waiting for a new thermostat to arrive. This should sort it as the kangoo dropped from high 90s down to high 80s when kicking its head in with a new oem renault rad.

Ill sort it soon as i plan on doing cambelt/waterpump at the same time.

Thanks for reading!!

I had nowt but problems with aftermarket rads on my meg. Waste of time and money.
