How to build a genuine 300+ Turbo Clio

[T.Trophy]

Suprisingly I was only at BTM on Monday for a quick catch up with Fred. My Trophy is at the fabricators still (1 year on the 2nd May), when I get it back I need to pull then engine out as I have some custom pistons and one piece stainless vlaves to go in. I haven't decided 100% on what cams to use but I'm looking at mildish ones as I want a sensible ish rev range and some decent midrange torque. But I will pop round when it's finished

Good to hear mate!

any pics?

[Dave/G]

Handy thread this, it's given some ideas for my build, quick question, what were your charge temps like on the gt2871r?

Did you not find the cast manifold caused a lot of restriction and reversion?

[T.Trophy]

I honestly cant remeber what the temps were and I've deleted my old data logs, I think they were high 30's/low 40's but can't be 100% sure.

Those were the exact problems I was having with the log mani at 374bhp, I don't think the small 53mm turbine wheel used in the gt28rs and gt2871r helped much either. I used an EGT probe and the exhaust temps were starting to get silly if we tried to push it any further.

[Dave/G]

I bet your charge temps would've got silly high if you had gone much further.

A mate of mine is building an R5 with a Clio engine in it, he's gone straight to a GT3071R cus he's worried the smaller turbine wheel will cause too higher temps

[T.Trophy]

TBH it was almost two years ago since I had this set up and all the problem I experienced were based around exhaust gas flow. The old F4R lump flows surprisingly well, I've not seen many others make 341bhp for 1 bar of boost. Who's your mate with the five? As I know most of the lads running f4r lumps in fives, in fact Ashy has a gt3071r on his F4R Five.

[Dave/G]

He's using an F7R which is the Williams lump I think

weve just built a 400+ clio turbo for £1000

What spec is it?

how much did you pay for each part?

And where did you get each part from?

Nearer £1,200 TBH


Some proper bargains to be had if you know what to look for.

Just read through everything. Epic read. Has caused some serious thinking..and assessing of bank account

[mark 5t]

i also want to build a low cost f7r turbo in the future.

my biggest problem will be wich clutch to use.

anyone got tips?

i am aiming around 250 BHP and this engine will only run trackdays.

[Chip-mk1]

Just use a 4 paddle helix drive plate with a standard cover mate.

[mark 5t]

i also have a r5gt turbo with 200bhp but this clutch cant hold the power so it thought
the f7r engine/gearbox would also have a problem getting this power on the road.

i think i also need a stronger pressure plate??


or will the original plate be strong enough?

[Chip-mk1]

Mine was a helix paddle and standard cover when this graph was done, and it did 10K miles like that:

[mark 5t]

i see this is a clio172 i am building a F7R i think the F7R flywheel is smaller this means smaller clutch plate
the biggest problem I see is getting the engine power to the ground
anyone got experience with F7R turbo engine and in particulary the clutch to use?

did you use standard cams you do any head work with the head? and what about the bottom end bearings and stuff you uprate those? or use new standard ones? cheers
