i had this thought the other day when toying with the meg conversion idea.
If the engines are the same then why cant you just rob the turbo?
but my expertise consist of PS3 lol what do i know about engines!!! Someone shed light on why this isnt possible?...
It is entirely possible but whether its practical is another thing, the meg lump already has lowered compression, stronger bottom end to handle boost and the managment that can run a car with boost.
If you want to go down the route or turbo'ing the clio lump then forget the high revving attribute, u dont rev a turbo car hard thats because as all of the torque (main / best feature of having a turbo over supercharger) generally speaking happens low down the rev range, so ur infact worse off revving it too hard. The Clio has a crank, rods and pistons that are as strong as a tub of utterly butterly, therefore u then have two options, lower the comprssion via decomp plate etc and run fairly low boost levels (10-14 psi if ur lucky) or run very low boost, (4-6 psi) and keep the standard compression ratio but the increase cylinder temps, risk detonation etc or go steel bottom end, doing this is ur best option but then you need to weigh up the costs of that to purchasing a meg lump.
Once the compression ratio problem is solved you then need to look at oil feed / return. Obviously a turbo needs cooling so you need to find a away of taking oil from the engine (probably via an adapter that connects the oil pressure sensor) to the turbo. Once the feed is sorted u then need to find a suitable place in the engine block or sump where u can drill it, make up pipe work and drain the oil fro the turbo back into the engine. This isnt easy as it cannot leak and the angle of the return needs to be high enough so that the turbo doesnt back fill and smoke.
once the oil return is sorted you then need to sort out the exhaust system - make a plate that allows the turbo to relase the gasses, another few connetions will be neede to connect to the inlet manifold to measure boost for the actuator etc.
again once this is completed u wil have to make all of the pipe work to carry the boost from the turbo charger to the inletet manifold, mount and intercooler etc.
Management, once the car has all of the other bits completed it will need mapping. The standard ECU hasnt got the capabilities to control a map sensor needed to handle boost so another alternative will need to be found.
For this you could probably get away with the megane ECU on the clio lump adoptng the map sensor from the megane etc of go down the route of KTEC's own gen90 ecu - again having to pay for the ecu and mapping is expensive.
I have probably still missed a few steps out but as you can see, its gonna cost a lot of pennies so unless u can do all the above urself then its probably not cost effective. Plus on top of all that the clio lump is not designed for boost, the megane is so you will probably experience other problems that are not known to us yet.
Hope this explains it a little better.
