megane engine conversion.

[Guest]

just questions i have about the engine conversion, ive looked back through loads of info on pages on the site and when i think i have it sussed out i find another post from someone sayin something wont work. there is a megane 2ltr engine at the local breakers . i would like to put this engine into my valver. questions i have are :
1) am i right in thinking i can use the valver head on the 2 ltr bottom end? if so ,does it just need a ordinary valver head gasket?
2)can i use the 1.8 gearbox and flywheel on the 2ltr engine? or will i leave on the 2ltr flywheel and just use a valver clutch?
3) will the 1.8 throttle body kit be ok to use on this engine then?. was planning on getting the head ports done and a cam and leave it at that on the head. would it be safe for me to have a go at porting the head myself or would i end up doing terrible damage? is it hard to do? would love to have a go at doing it myself. i will be putting some kind of engine management into it too. was thinking mbe or omex as they seem to be reasonably priced .
if anyone can give me any advise it would be appreciated. ive taken engines out and apart before for a friend whos a mechanic , but never put them back together myself. would i be able to do it myself or is it a daft idea?

1) use a 2.0 headgasket
2) yep, 1.8 gear box and flywheel. cant use meggy fly wheel
3)throttle body will be fine, same as williams.

simplify it. Just use the entire megane engine, especially with throttle bodies. there's s better throttle body manifold available for the megane head, and the head is very very good once it's been re-worked. The megane flywheel is easily compatible with omex, you will need the megane or 172 clutch though. use the 2l head gasket on a 2l block.

thats ok if you want to spend thousands,i've fitted the complete megane engine and converted it to run on valver managment

well i was thinking of using an mbe ecu in it anyway if i could. i just seen that there is a lad sellin a megane bottom end with williams head in the for sale section with only 500 miles on it, am wondering if i would be as good to buy that? only thing is i would have to buy ferry tickets to go over and pick it up which would cost me another 400 euro on top of price for engine.

it surely isn't hard to convert the meggy loom to match the valver loom :?

based my answer on the fact he said he wanted to use management and fit throttle bodies in the first post.

just an update. my engine is bought and sitting out in the shed. i bought an engine, box, partial loom, ecu and all the bits that bolt to the engine from a 2l megane coupe. f7r 710 is stamped on the block. have to clear off my credit card bills before ill be able to start at it properly though. was just wondering, is there much gains from headwork on the megane head since it already has slightly bigger valves than a williams? im needeing to get rough ideas of prices before i can plan the project properly. what, roughly, is the going price to get headwork done in the uk? how much money for certain stages of headwork? im still planning on throttle bodies and mbe management. also considering doing the bottom end. im a bit skeptical of putting in high compression pistons cos the pump fuel over here has a terrible low octane rating, and im afraid if i raise the compressinn ratio it might start pinking?? would it?and will the high compression pistons have a noticeable effect on the engine, driving and acceleration wise? is the standard bottom end strong enough? or if i was to do pistons would the standard rods do? im looking for peoples own experiences and advice. also what is the type of throttle bodies that i need to look out for, am i right in thinking jenvey 45s? im gonna watch ebay to try get an idea of what kind of prices they are making. is there any particular length of body or trumpets i should be looking for?

is there much gains from headwork on the megane head since it already has slightly bigger valves than a williams

yes as the port shapes can be improved bigger valves aren't needed but port and seat work can show 20/25bhp....approx 400/500 on these iirc..

and will the high compression pistons have a noticeable effect on the engine, driving and acceleration wise

about 5% across the range

is the standard bottom end strong enough ....ohh yes..or if i was to do pistons would the standard rods do ....yes unless increase revs above 7000k..bolts can be a useful upgrade

also what is the type of throttle bodies that i need to look out for

jenveys are fine/great along with the right manifold..

is there any particular length of body or trumpets i should be looking for

yes they need a shortened rad to get an effective length really..

try stan at apd http://www.ap-developments.com/ for everything you need

all this depends on what your trying to achieve though bhp/ft/lb wise really
