well wot does it matter even if you have a reference?? the mapping will still have to be adjusted live, and so it will inevitably be mapped specificaly for your engine. i.e. if someone comes on here now and says their engine was at lambda=1.1 at max engine speed/load (with the same mods), YOU...

mix some lacquer and black paint, then spray

As has been stated the ECU will pull fuelling back to stoich on cloosed loop lambda, but the ECU will run open loop lambda above a certain load/speed boundary, and take a preset fuelling algarithymn for maximum power (where lambda=0.88, NOT 1 (stoich)). But as Ben has told you, the AFR of your...

crossflow is the name given to the design you have pointed out....inlet and outlet on opposing sides. increases the overall flow ability of the head. yours will be cross-flow mate, dont worry about it!

injectors make a ticking noise by nature of their operation. u sure it isnt the followers mate? petrol additives are pointless, they dont clean the basket in the injector itself...its too fine they need to be sonic cleaned to do it properly. like i say...u sure it isnt the hydraulic...

immobiliser or fuel pump relay

ok ;)

i see ;)

sorry havnt read whole thread...can some1 summarise wot power it achieved on which dyno & r/r! cheers!!

the megane head needs machining at the end of the exhst cam to accept the distributer boss. then u need to mess on with the inlet manifold and adapt it and the clio loom so that they are compatible. then ud need to map the ecu unless u can diy it then i wouldnt bother mate fit t.bs if u want...

take it u mean meg F7R head?

yeah had major probs with it...i cant get any communication with the ecu. its on stnd willy map, and it goes well considering its far from set-up...mapping is wrong and the cams arent timed. got individual T.Bs on the way tho, with an Emerald ecu;)

it helps cool the exhst manifold area really....heat "release" only occurs at standstill naturally if u were to use the non-16v bonnet u would fit some sort of vent

id say so....mine goes to 7250 with ease...im sure it will go further aswell. but there is always a risk a component will fail have u got the cams for it tho?

the bonnet does fit, but it rubs...needs modifying on the inside.

crank and pistons in the meg are more up to the job. only way to improve is forged pistons with the crank/rods lightened to suit (there is no benefit of lightening crank unless the pistons are lighter).

the mounting holes are on the clio subframe

he has a different map for the 2.0

Because then we couldnt charge ££££££ for detailed engineering work ;)

ive seen it happen on a Mitsi Pajero off road vehicle, so it can happen on a Clio. granted its not likely, but equally not impossible Are you running an enclosed airbox Ben?

He means large volumes of water that may lead to hydraulic lock....

Its all true!!

A typical sensible reply to a typical cliosport thread. cant answer questions straight...deary me

eh? that a bit of a large assumption. why would i only be able to buy pulleys when i finnish the head work? i havnt finnished the porting yet..i told u that, and thats wot i said in my progress report on retro-renault...and so wot? ive been busy. its not exactly crime of the century! So just...

What issue would that be then?? How would you know mate....youve never tried it, and besides, you dont know what i have/have not done...apart from my BRIEF mentionings

V6s are slow down the strip...there was a mk1 16v at the pod that out paced two of them

PMSL!!!!!!

damn..u beat me to it!!

should be good! You got a deal on that standard head ;)!

boring the head out?!! williams has longer stroke and slightly larger bore to give 2.0. the longer stroke and heavier crank reduces the max rpm. it also has larger inlet valves. so...to make your F7P into 2.0, youd fit the williams pistons and crank. the block needs machined to accept the...
