No I’m actually going to leave the ports well alone. I’ve grown up being told about smoothing ports to a mirror but I’ve seen M3’s with those weird lines in the ports and again if Renault have done that and achieved that BHP it must work. I’ve been reading so much this past week about it, even...

The smaller ports must work, Renault got 180bhp from that and you can run a turbo up to 280bhp so it really can’t be that’s bad. Thanks for the replies so far people

What a minefield! I’m putting a turbo on mine so currently looking in to which head will be better for that. There is just so much info out and lots of it conflicting. I’d love to own a dyno and do back to back tests to find out what is better.

Thanks for that link! So is there any reason why people would go for the smaller ports? Surely bigger would be better, I’m up for being educated though.

Ha. Thanks Steve.

Yeah no problem. I’ll get them tomorrow.

Bloke - I don’t know. The engine was removed from a ph2 172 so assumed it was that. Comparing them side by side the only difference is the exhaust ports are massive and have been machined. Maybe I’ve got real lucky and it has a ph1 head on it.

Brilliant, thank you. Exhaust ports are huge compared to the 182 so It looks like i have a ph1 head.

Hi guys, I’ve got a question I can’t find an answer for and hoping you can help. I’ve got two heads, 172 and a 182. On the 172 both inlet and exhaust ports have been machined, I would say it’s a standard job and not aftermarket. On the 182 only the inlets have been done, again I would say from...

hi all, been using the forum for ages now and after having to sell my cup to buy a house I'm now back in the market for another clio. I've seen a few clio turbos for sale recently and after driving an r26 I think that engine would be a riot in the clio. Is there anything to look out for when...

That is interesting. Do you have any more details of this? Also, as it would be a low blow unit plus not running much boost could you do without an intercooler or is it essential? ive seen that JMS inlet for sale and part of me thinks all this playing around with a turbo the JMS would be just as...

Hello people, so me and my brother own a track day 172. its road legal but majority of its life is spent on a track. its more than capable and its amazing fun, I have just as much fun as the 50k gtr's that whizz past me but we keep thinking a little extra power would be nice. so I wanted to ask...

When you see performance cars from the factory they are not mirror finish For example bmw m3 head the ports on that are very smooth but not a mirror finish. Im sure if getting a mirror finish help improve bhp/torque/flow or anything like that then bmw would have done it from the factory

If you rung Renault with your reg they will give yiu the radio code have done it a few times now

I was in an l200. Normally in a blue 172 black bonnet

Saw a trophy in eastry the other night number plate somthing like t9phy

Got a set of 15" oz f1 and need longer bolts to suit a 20mm spacer 1 set come with the spacers and they just fall through the alloy the chamfer (sp?) Dont seem to be big enough. What does everyone else use?

No but I cant be bothered writing out a massive list of bits it had for you to just argue cos you no best was bored of you about 3 months ago

Thats what I ment if its over tolerance then it needs a bore. Its not just road cars we build just finished an m3 track car thats just had 30k stuck into it. Our engine rebuild cost wasnt for that wasnt 4k it needed another head and a piston as it had dropped a valve and he is still going fine...

Its a proper rebuild mate it wont make them lose in the bore if its over tolerance then it needs a hone. Simple stuff Not gonna argue online about it my dads been doing it since he was 16 now 45 and we have had our family buisness over 20 years now rebuilding engines so im gonns go with what I...

Thats a load of rubbish you dont need to spend 4k why rebore an engine if it aint needed thats stupid a proper hone (not flexi hone) and a new set of rings will outlast the car Also new valves? Seriously if they are straight then you reface the valve grind the seat and its like new there is...

You could cut the price on above if you just wanted to head and sump the unit flexi hone new rings new bearings and built back up with a skim and new gaskets but its best to have it done properly

A proper full refurb (strip it to every last nut and bolt acid dip and degrease and rebuild with all new gaskets head skimmed bored or honed depending what it needs new piston rings new main and big end bearings crank grind if needed) your looking at around £1000 mark with a 2 year guarantee...

Brake and clutch cleaner is pretty good for cleaning bits up

Got some funny noises coming from brakes after the track day at Bedford think the discs might be a little funked
