ah yeah cheers, found it. yeah the mk2 head seems a strange starting point to me, but was thinking more any physical constraints to using it as apparently it's down around 50bhp and 40ftlb! However yeah I'd forgotten just how much difference there is, so perhaps it's on a mk3 itb setup and of...

Hi mate, don't suppose you got a copy of the dyno graph have you? Wouldn't mind seeing the shape the R3 cams give, I'm having a set profiled to see the duration and lift etc, trying to amass as much mk3 cam info as possible before I go 'big'! :) Also, I know you went mk3 head on mk2 block -...

well yes and no! I am going to get a very cheap car for doing short and crap journeys, certainly before winter is here. But I don't intend for this to not be considered a daily still really, so chances are the school runs will drop off from it's duties... but then again as I work from home I...

Oh yeah another forged motor mate indeed, it's an epic spec really which is just cams and itb's away from some serious grunt. The close box it has means it's already quick to be fair, does 135mph in 6th flat :) If you want to ruin a 200 which is one of - if not the last decent N/A hatch made...

Also PMS low spec entry engine makes 185ftlb on a mk2 head, so 190+ on a likely better head based on a mk3 to begin with... is not at all unrealistic tbh.

Yeah I was surprised (and sceptical in equal measure), but it's a fully built motor from Ashford and the head was done by Ilmor, it's most certainly not some parts bin engine. My last engine on these cams made 215bhp and 182ftlb, but this is the difference between essentially a purpose built...

Same 403's but it shares very little with the last engine really. They are just a stop cam gap before some big vvt delete cams and itb's, but just wondering if it could be why were seeing high egt's and again it's very knock sensitive with these mild cams and a high static cr. Hoping it...

Ah ok, I'll def need to quiz them a bit more about how they measured this then before I chuck more bits at it. Cheers

Hi mate, did you use a stock 60mm TB on this or is it ported at all? Had my new motor mapped now and found to be showing some vacuum so potentially looking at a restriction on the inlet, I'd be surprised if TB and I need to ascertain how the vacuum was measured etc - but as I know you're also...

Are you sure you even have a cat now, the Akrapovic system is manifold back and decats the main cat. Unless you just have the Akrapovic 'slip-on' which is just the backbox. Sent from my HTC One using Tapatalk

Yeah these diags just look to have come straight from the RS parts PDF. Found a mk2 copy here: http://www.renault-sport.de/uploads/tx_news/Teilekatalog_Clio_II_Cup_2005.pdf section 10.84 and 19.05 for the parts.

It's just a sandwich plate basically, Google says the mk2 Cup Racer apparently had one: And integrates to the cooling system: I actually happen to have a spare one I photo'd the other day as came with the new Mk3 block etc:

Ah yes good point Bigash, I do have the stock mk3 modine arrangement. How effective that is I don't know.

Too busy, meh I've never heard that one! Bonnets are meant to stay shut anyway you know ;) For 5k on the road yeah that's a bloody high temp really, very odd. Guess the pressure could be sending too quickly through the cooler, however.... I wouldn't expect oil to get anywhere near that without...

Yeah there is, speak to Mitch at Proline about a manifold mate: 48mm SF's on a mk3 I'm not using an oil cooler, doesn't need it tbh. 111deg was the peak I saw on track, decent Millers CFS NT will laugh at that all day long, I change it every 6k. Anyway, turns out my engine failed due to...

I will wonder for you then! Yeah I can well imagine, essentially identical curves to mine (mine peeks 182fltb from 5000-5300) all the way to 6500 when yours just carries on relentlessly. Coupled with the light mk2 shell you have, batshit and legitimately so. But for me the noise is just so...

Nice curves that, almost identical to mine from 3500-6500, but mine the torque takes a nose dive at 6500 and so the power flatlines, whereas yours keeps torque to a much gentler taper down and power therefore keeps on for another 1000rpm. If I was keeping forged pistons I'd def slap a set of...

Good effort mate. How much was done to your inlet? Extensive or just spit and polish!? My K20 plans have been abandoned (annoyingly so because I've got a whole engine and box to shift!), but it's encouraging to see results on the plenum. 1600rpm idle though, WAY more lairy than 403's dude...

oh I thought it looked like it would give a low CR, looks in the pic like a kinda dished piston crossed with a direct injection like centre to it. Unless I assume then it is the whole circumference of the outside that is raised above the deck height to give the high CR? Anyway the weight of...

What do I have to do to fit those..... mill the block into a 2 cylinder perhaps! 😂 Not liking the look of what the static CR would be either!!

Yep exactly that the radiant heat as it's cycled through the head. You could also get an oil pan heater (the Yanks seemed to favour Wolverine ones)...I did a fair bit of research and both seemed like a great idea. I tell you me and hindsight don't get on too well! 😂 Yep R3/225...

Yeah if you can't beat them - join them!! only sod driving a Civic so making a French version ;)!! Engine arrives tomorrow and got a lsd box already so should have an idea if it'll fit :tongueclosed: Long term plan will be medium to big for it of course, but always OEM cast style pistons! You...

Yeah forgies for a 2nd car only now as far as I'm concerned, and a garage wouldn't go amiss either to wrap it up over night! I was perhaps a bit naive to think what was essentially a race engine would do me multiple years starting most days inc winter temps!! Live and learn! Pistons were PEC...

Awesome...she runs :) I know it's un-mapped but nice bit of lump to that idle :) I think you should make 220+ with those cams for sure. But I certainly wish you more luck than I had with mine; 1 year with 10k miles and 2 track days and the rings are shot! So I give up and am not thinking of...

Yeah I would prefer black/gold fittings and black stainless hose now - but as I bought all the stainless hose and blue/red fittings long ago to go in my blue S2 Rallye (but never got around to fitting), I wasn't buying it all again! You can't actually see any of it in the engine bay anyway as...

Good idea to remote mount, ignoring the practical benefits - aeroquip in the bay is always a win!! ;) Thread fit's like a charm though and no leaking at all since it was fitted last April. The only place I had to deviate was on the sensor fitment itself; a 1/8 NPT male to -4 JIC for the...

yeah it just surprised me tbh, I know it's all healthy still as it made 182lbft at Surrey RR a few weeks ago so compression is still good and high. Guess it sounds like some 10wXX is needed to cover winter at the very least perhaps. I'll look in to it. cheers

I was perhaps a bit naive but I thought using 4032 alloy forged pistons with a tighter gap then they would have been fine.

Indeed, Summer was fine - 1ltr every whenever, maybe a few thousand, I never felt the need to log it anyway. But as it got cold and when I changed to Millers CFS Nanotech over the Milers CFS Racing I noticed it was getting thirsty. Logged the llast top up and was 1ltr in a 1000miles - was during...

Do you run a thicker oil because of the forged pistons needing bigger piston ring tolerances? I wasn't quite prepared for the oil consumption of forged blocks(!) so was in the back of my mind to maybe try a 10w40 or 10w50 over the normal 5w40 grade. I didn't notice much consumption until the...
