GDI Clio 172 (ITB'd) VS Subaru Impreza vid

[BenR]

2.2's for a road milage car.........not such a great idea. Bores become thin, cylinder sealing area becomes tiny (prepare for blown head gaskets if its not built perfectly). Plus the 84mm pistons on the market are plain crap and not something i would be running on a daily basis. Infact, none of the forged pistons on the market are that impressive, and most are pure junk, certainly wouldnt be wasting my £500 on the crap thats out there.

I would stick 2ltr, stock crank, forged pistons and rods.........a steel crank is just a total waste of money as you wont make the torque to break one, nor reach the rpm to break one with the stock RPRF valve actuation. Hell.............you wont even really need steel rods without good purpose.

And as far as i know, from the pictures, andy is running a stock crank.........cant see any logical reason to run a steel one.

And on a side note, our AWT pistons will be out in the new year. I've pushed the manufacturer to spend the dosh making a new forging die specific for the piston design i require making it ultra light and ultra strong. It'll be made out of far superior alloys, with superior rings and a piston taper that will allow 8 tenths of a thou clearance when running (hot) without issues.......which means zero piston rattle from cold. And even better........they will be cheaper than the best offerings out there at the moment, there will be no reason for anybody to buy anything else.

Is a rebuild even needed if its in good nick?

I love it when you get all geeky

Will give you a buzz tomorrow and arrange to come over either friday, but most likely monday.........if your about?

 

[BenR]

will be there....just give us a bell like usual.

 

[TheJesus]

so just pistons and headwork then your saying?

Andy does have a steel crank... I've touched it! lol

... it looks great too and I want one

 

[BenR]

you have one, the stock crank is a 'steel'

Stock one is fine to over 8k, dont even see a point.

 

[TheJesus]

yeah, my mistake, it's a stock one... it was all clean and shiney n' stuff though... lol. either way, I want BE work doing though, dont want to worry about all the strain on the stock BE and it losing compression (even though it's almost as new in that sense).

basically I wanna be running 250+ bhp in time for the Nurburgring trip next year that I'm going on... looks like I'll be going with the Scooby lot now, so will need a few more ponies... not really bothered how it's done as I wouldn't understand it all anyway, I just like having stuff done to my cars as I tend to keep them a while...

250bhp! get your wallet out

bottom end really is fine, no need to touch it

I tried to find you data of the car, but couldn't find it. How much hp and what are your mods?
And how much hp for Subaru? I can't believe there is a Prodrive chip in it. It's a very slow Sub

I couldn't see the vid but if it's a UK classic the PPP only pushes it up to 240bhp on the WRX which is a god but there's the weight to be factored in.

250bhp in a Clio sounds pretty bonkers

cant see it being too rediculous like you are making out. 182 manifold, some headwork and BE work and it should be about there I'd have thought anyway... plus cost is not an issue, I'm doing it for fun and to have something different. I think you're scared it will be quicker :rasp: lol

Neil, fook knows what power it is, it's not been RR'd that I know of, but it's about similar to his last one he says... that was around 260bhp+ iirc

 

[Fred@BTM]

mate we're on 205bhp @wheels (approx 240), thats about the limit (without spending £4K on the head), and we've mucked about with comp ratios galore

trust me on this, you won't be getting 250bhp, speak to BenR if you don't belive me!

headwork and manifold don't gain much, and your looking for 35+bhp!!!

 

[ben_p]

what about a ebay chip?

 

[lewisniven]

yeah, the resistor of eternal glory could be what it needs, lol. Seriously tho mate 250bhp will be mad, loved the vid tho.
