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
