Looking good can't wait to see this.Originally Posted by Matt Cole
Ref crank angles, you still using the previous map for this engine? if so then it's just a case of using a timing gun enter the value the light flashes same time as TDC mark passes enter the value into WARI wizard and it will do the rest for you
Cheers James. Yes same map but different gearbox and flywheel. I guess I'm going to have to start from scratch. How do you find the angles? My old timing gun has died. The adaptronic 420b/c has the tables as you say but I'm not sure on what to enter as a start!
Hmm, gearbox won't make any difference to getting it running its the flywheel tooth patternCheers James. Yes same map but different gearbox and flywheel.

is it still 60-2 fly still?
It's a Megan 225 patern solid flywheel so I guess still a 60-2
This install looks fabulous Matt
Thanks Trevor. It's been a labour of pain and a lot harder than I first envisaged.This install looks fabulous Matt
I've tried to keep the build cost down, so you won't see over the top priced parts such as tial gates etc and fortunes spent on bling.
It's alive!

great work matt
you best get this to pod
Not quite Mick. Had to take the cat cams pulley off......great work matt

why matey whats up?Not quite Mick. Had to take the cat cams pulley off......
Is that cracking I can see in the pic?!
Mick - My post in the magic sponge detailing thread today - I hadn't even noticed it was in articles. I just thought Pete had put a load of open discussion threads up in a new section. Apols
Yes cracked at the centre. I'm so pissed off!Is that cracking I can see in the pic?!

Well, catcams replaced my pulley with something much better.
Re timed and all back together. I've also modified the cover so I can play with the timing. At the moment it's set at 4 cam degrees of advance.
It looks awesome
Well done
With seeing all these excellent engine swaps, I am swaying towards doing an engine conversion in the future but would most likley look at f7r or f4r then turbo them
Awesome work Matt, I'd really like to see this in the flesh. It looks like it's been a mission and a half to get it fitted and up and running - well worth it though. Let us know how the MOT goes!
This just looks like an absolute animal and it doesn't look like other any GTT I've seen either. Fantastic effort Matt. You should be proud.
Get some more vids up when you can once it's on the road and all set-up etc.
Thank you for all the kind words guys!
Hopefully reading back through the history of this thread you may gather that the most challenging part was fitting in an NDO 6 speed gearbox. Yes, I know the VAG conversion is tried and tested and requires less work, but I wanted to keep it all Renault and no one else had attempted to do it. The diff is quite big and fouls everything, so quite a bit of modification to the chassis leg, sub frame needed to be undertaken. The engine is sat almost upright and forwards to clear the diff! The 172 head is married to the F4RT block which isn't a straightforward fit as some might say
I then had quite a bit of space for a full equal length twin scroll tubular manifold design. Its not the best in fabrication terms and I would like to improve on it in the future.
As winter is now here I didn't think there is much point in taxing and testing the 5 as I probably wouldn't get much use. So over the winter I'm going to do a few further improvements mainly to the interior. I thought I would fill some more holes in the centre console
this better be at pod or ill be very disappointed in you MR Cole!! pmsl

That's the plan Mick unless something horribe happens......

Today I decided to look at the suspension a little. Heavy and hard acceleration can cause all sorts of grief for the wishbones. I decided to steal turbo teds idea of using drop links. Hopefully should prevent the wheels bouncing and offer a little stability on the wishbones.
Looks like one of the heater tubes from inside the car, love the idea!
Couple of 100 miles done and I'm using it for work!

Please do. Well done on what is a truely great build, very testing but so worth it.:
Like Trevhib said the look of the car is special and I love how you have kept it all Renault as well
evening Matt, trying to locate your 172 hub conversion, think you need to add it to this thread :-)
Breaking GT driveshafts was inevitable, so on with a 172 hub conversion:
Horrible things:
And all fitted:
The hubs are much bigger than the GT's. They also give about 7.2mm extra track each side. I machined the stubs down so that a GT shock could be fitted, but also drilled the shock mounting bolt holes from 16mm to 19mm, and then used the Clio shocker bolts. I had custom one piece shafts made up. I did fabricate my own initially and drove around on them to make sure everything worked as required.
The Hi spec caliper rear bodies had to be changed to fit the 172 hub flange with new seals and recon pistons:

I wasnt happy with my original manifold so decided to fabricate a new one using a single 50mm wastegate with a divided collector.
New TS 50mm wastegate:
and on with the manifold fabrication using sch10 pipework:
The waste gate is left open ended (screamer) and exits under the car
The fuel system needed an upgrade as having no decent tank baffle would make exiting a roundabout difficult with the fuel starvation. I fitted a swirl tank and upgraded all the fuel lines to 10mm ID:
This set up is underneath the car in place of the reserve fuel tank. Im using a Sytec "044" equivalent. Its very noisy! You will see i added rubber mounts to the pump. These made a huge difference to the noise in the car.
The one thing about this conversion is carrying the extra weight of the engine , box and turbo. It has a tendency to move. I had 5 mounts which were ok, but decided to add a 6th:
The only issue now is i get increased vibration in the cabin. Its almost like its solid mounted! The engine is pretty much solid now with just enough give to allow some parts of the drive train a bit of an easier time.
Although i dint have a problem, upping the boost might cause the engine to breath heavier. I needed to relieve the pressure by modifying the crank breather cover. I figured that running two large bore pipes would increase the overall volume for the gas to escape, but still keep the effectiveness of the oil baffles:
The last image is work in progress showing only the one pipe to the catch tank.
Picture of the engine bay roughly as it is today:
The keen eyes amongst you might notice that the bulk head/firewall has been re-instated. Made a massive difference to keeping fumes out of the cabin.
New exhaust time!!
Angle off the back box to go over the rear beam. Note the intricate shapes to make the fillet:
Lots of bendy bits:
Comparison next to an old scorpion i had lying around:
Fitted onto the car and over the rear beam:
One of the worst jobs ive had the pleasure of doing on the car!!!
And a couple of pics for those that have not seen it complete. I took these for the agreed value insurance:
The seats are from an Impreza bog eye. Not the easiest to fit at all
In April, it went for mapping to Lord Scoffs at EFI parts. Chris is an absolute pro and highly recommended:
And the result was 441bhp at 21PSI
Comments always welcome on the graph, especially the curve and power band. If i had more time on the rollers, we could have re-gapped the plugs and played with the cam timing, but essential, there is bags of turbo and injector left, so it could make more power. The only limiting factor will be the clutch.

Absolutely stunning work you are another legendary rtoc member and I am in ore yet again. I haven’t read through this since 2017 so I can’t remember what sort of power are you going for, surely that is enough and it going to hard enough to exploit it as it is on the road but loads of fun learning to master nevertheless

I said anything over 400bhp was ok. The turbo can do 2.5bar easily, so another bar of boost would see it over 500 i imagine.
Yes 441bhp at 21psi currently. I think my clutch would struggle beyond this so leaving as is for now.

All is very well. Couple of winter servicing jobs to do such as cam belt and dephaser. I have a small crack in the inlet manifold runner, so will need to get that sorted.
My next challenge is power steering options. Im looking at EPAS, possibly from a Clio 2 1.2/DCI. The issue is fitting the motor and top of column within the GT dash without hacking anything to extreme.
Ill be looking at options for this over the next few weeks.
