172 engine in an Elise?? The Elise been out a lot longer than the 172 think it came out on P Reg or something so the 172 engine wouldnt have been about in its present form. Anyhow hasn’t the 1.8 K-series got shed-loads of tuning potential I think that’s why they used it.In reference to the 172 engine in a valver.. I had a look at doing this after i wrote me 172 off, the main concernes where:
* The height of the engine, mainly due to the inlet manifold.
* Mating either a gearbox or driveshafts to match the engine etc..
* Getting a exhaust manifold to fit
* And Then sorting out all the wiring from the ECU etc...
Its probably doable with a bit of work, perhaps having to tilt the engine to fit inside the valver engine bay, and modifying a few things here and there such as manifolds and subframe etc
Someone will get round to it one day, but i guess your gonna have to ave a bit of spare time on your hands and a fair wedge in the bank
They originally intended to use one of the F7 engines from the Willy (F7R) or Clio 16V (F7P).Quote: Originally posted by Tim-Grove on 09 November 2003

The deal fell through because Renault got funny and were using the F7R in the then forthcoming Spider.
The engine could probably be made to fit but you would need to swap most of the vehicles electrical/injection system as well due to the immobiliser and obd system.You couldnt use after market throttle bodys due to the variable valve timing is controlled by the renault injection computer.
what have they done about about the valve timing.Have they just disregarded it and made up the loss of bhp with the throttle bodies.The variable valve timing is only active through mid range revs and only under certain conditions.How could they control this accuratly.The actual operation of the valve timing is controlled by a solenoid which controls oil flow to a two position dephasor on the inlet cam.The solenoid is easily operated but doing it at the right time would be difficult.
Just about any engine conversion can be done to any car, Ive stuck a Vauxhall Xe in my mini and there are many Honda vtec ,Toyota ,Rover conversions even a front wheel drive Rover V8 in a mini so putting a 172 motor in a 16v shouldnt be too difficult.
As for the VVC on the 172, from what I have read it only works at low revs to reduce emissions (not like a Honda Vtec system) so you could remove the ecu control and just have a permanent live to have it activated at all times which is no worse than fitting a wilder cam profile.
I did put the K4M in my Clio1. Was a lot of work, but it was possible, also wiring and ECU....

I think the F4R is also possible but bigger effort.
