Well they helped to take my car around the nordschliefe in 8:31 mate, so they'll be plenty good enough for UK roads. Tbh I loved them to bits and sometimes wished I'd upgraded to the custom kw's instead of the ast's.
Well still waiting on overnight parts so I decided to drop the coolant and make a start on getting the engine and box ready to lift out. Also had a chance to offer the new smaller ally rad up to see what mounts I need to fabricate.
You can see in this shot some of the mods to the slam panel for...
The majority of the rollers will be inside somewhere then probably clinging to the magnet inside.
The cup is essentially the same mate, it's the plate and casing of the diff that's not, due to having 4 holes drilled and tapped in it to hold the plate secure. You should be fine to try it...
@EVOgone heres some comparison shots of the 2 heads. Inlet ports only as the exhaust ports are identical in position.
172 inlet port: Lower down in the casting and not as wide as the 197 port. The head is upside down in this pic.
197 port:
Slightly higher up in the casting and substantially...
Have you seen the difference between the 1*2 and 197 ports though? In fact what head are pms running? Is it a 1*2 one? I've just had a watch of that video you mentioned about in your pm as well. Interesting results.
How many metal filings came out when you dropped the oil mate? I imagine they've all been quite well chewed up by now tbh so any damage is already done. Fit the other diff cup and run it mate. It's not ideal, but if the box is now fucked it'll show itself reasonably quick. If your wanting to...
Are you wanting to fit the 182 diff into your gearbox then? No speedo drive gear on the 182 diff for a start and you can't just fit the part that bolts in either unless you drill and tap your original diff.
It's not something I'd do tbh. Your better off getting the renfort plate off eBay and...
Agreed. The big hp duratecs are running 52 or 54mm butterflies just to get the transition right, which is where the 197 inlet ports are similar in terms of size.
The Ashford f4r on YouTube is also running 50mm butterflies, possibly bigger.
Needs 50mm butterfly's to get the maximum out of itb's/this spec ideally, and it's only 45's available off the shelf. It's all about the transition/taper from the butterfly to the valve face, with the optimum being around 7 degrees. You can't get that with 45's unfortunately.
A mate of mine who...
Its the longer primaries mate. The Clio 197 R3 maxi and maxi evo manifolds have huge primaries in terms of length.
The collector will have some effect on performance but nowhere near as much as the lengths.
I can measure my pms one if you like?
I'd would definitely fit a set of arp's mate. It's added security and peace of mind, plus it's much easier to do when the engine is out of the car.
I'm just a bell end mate. That's why I never bothered fitting any in my standard engine.
My original engine has been seeing 8k on standard everything...............for quite some time now. Lol! No arp rod bolts either!
New engine will/should/better (delete as applicable) see 8k safely.
If it lost all 36 needle rollers, that's the main diff bearing that failed. I would imagine that when they were floating around inside the box, there were a fair few of them getting between gear teeth and wreaking havoc tbh! It could easily force the shafts apart and damage the casing without...
It's the dog gear on the gear itself that's come adrift mate. Very easy repair to do but it does mean the box needs to come apart. Your looking at about £160-£170 in parts though just to do that particular job. I know these gearboxes intimately! Lol!
It's demise has definitely been caused by...
Gearbox nearly finished now. :nomouth:
Ok, so maybe that's not a jc5, but it's as equally unreliable. Lol! Got a full strip and refresh to do on this, then refit it. 9hrs of fun. I thank you.
In jc5 129 news I'm waiting on back order parts to arrive overnight from Tokyo. Allegedly. So nothing...
