Do a google image search for R3 exhaust manifold mate and you'll see what I'm getting at. It looks night and day different to the original 197 manifold. It's a proper race spec bit of kit. So is the pms one.
I think you'd struggle to fit the R3 manifold mate due to space confinements. They're a 4-2-1 with really long primaries and they don't look like they follow the same path as a 1*2 manifold. They're serious £££££ to buy as well unfortunately. Possibly your best option is to buy a 2nd hand 197...
Correct, you would have to re-drill the block to suit the jc5 pattern. Cam followers are an issue over 8k or if the engine spends majority of its time in the upper rpm (you say yours is a race engine so I imagine this to be the case). I've heard of them breaking and also flipping off the...
Exhaust ports on the majority of f4r's is small mate other than the ph1 172 from what I've seen. They all have the same size valves though in the 2ltr range.
There not the nicest of jobs to do on your back and a lot easier if on a ramp. I did mine on my back and it took about an hour from start to finish, so that includes jacking it up and back down.
Stainless bolt will be fine as iirc the originals are only 8.8's anyway.
The block is different in terms of the water pump is in a similar spot to to where it is on the xe, but as for if the block is stronger to avoid flexing issues I couldn't say chip. The block I had, had no main cap tops so it was disposed of.
Yes mate bore and stroke are the same on them (as in 1*2, 197 or meg225) but the block casting is different on the 197 to a 172. It's stuff like the bell housing bolt pattern.
Yeah maxi engines were high comp pistons, heat treated original rods, lumpy cams and a fancy exhaust manifold. Head...
197 block and f4rt have the water pump driven by the cambelt Morgan for reference. You need to drill and tap the 197/225 head to accept an idler roller like the 1*2 has to make the head work on a 1*2 block as well.
OP as Morgan states, the R3 maxi engines do indeed make the numbers, and that's...
Difficult to say without seeing the car at its current ride height, but it will be out. Mines currently set ridiculously low anyway so it's possibly not representative tbh.
I thought they were 17mm tbh chip on the Clio but I'll stand corrected. Either way to open it up to 17mm isn't an issue though. The only bit that concerns me is the extra leverage adding to the elongation issue. This is what I've been discussing with my machine shop. We possibly have a solution...
That's what I've already got chip, but it's more a case of if they will still elongate the bottom ball joint hole. I've had quite a few sets of hubs delivered to me already that show signs of that happening even from the standard joint!
That kit we've done is obviously more radical to overcome...
I only fitted them because the front wheels just look lost in the wheel arches when they're lowered! Drove it maybe 100 miles and tried different geo settings to try and overcome the change from neg to pos scrub, but all to no avail. Removed and sold on! Oh definitely because ricecar mate! Flol...
In short mate - no it can't be done. You'd have to completely redesign the bottom ball joint and rest assured that would cost £££'s. The only possible option you've got is searching through a host of parts books from a factors and look to see if there's anything that's similar (possibly mk2 golf...
Where are you getting the angled spacers from? The ones Jenvey sell are are SF bolt pattern, unless there's some others on their site? Or are you having them custom made?
