5 GT Turbo R225 ENGINE CONVERSION

Has anyone done a Megane R225 engine conversion in a 5GT. If it possible can anyone help with some advice things like gear box to use etc etc.

Thanks
 
there are a few that have though it depends how you want to do it. the easiest would be turbo the 172 F4R and use the stock 172 box over the 225 F4RT and 6 speed box, the 6 speed will require fabrication to the chassis to fit where as the 172 engine and box is near enough bolt in. I am generalizing with the F4R engine rather than just the 225 variant
 
The f4r 774 is generally more expensive than the Clio engine , bled er it's had a lot of the legwork done for you. It can take upto 300ibft of torque.

The Clio engine will need rods to do that.

Cheaper still the f7p is another route .

I did the F7P conversion last year but i sold the engine in the end wish i kept it know.
 
Will the nd0 even fit in @Adey? Though most were mated to a jb3/jc5

anything "fits" if you can cut weld and fabricate. The other way to do it is F4RT engine, re drill the block and fit a 172 gearbox along with flywheel and sump (sump will allow alignment of gearbox)

If it was me doing it id buy a cheap clio 172, swap it all over into the 5 then turbo it after. long run it would be easier and cheaper than buying everything individually.
 
you can use bits out of the meg engine but tbh its not worth it. To get to meggy power on the 172 engine bolt a blower on with a super thick head gasket to drop the comp ratio and you will see 280bhp with the right turbo and mapping. after that its forged pistons and rods same as the Migraine
 
yeah but no point using them in a 172 block as the pistons dont fit properly due to the clio having VVT and the meg not so they will meet each other. When you add in machining them to fit or loosing the vvt you might of just saved stripping 2 engines to build one and just slapped rods in with clio specific turbo pistons
