it took me a while to figure out that Osmo oil is for the shed, not the engine!
Drop the motor mounts 1/2”? I’m sure one of the racers on here has done it to get his exhausts to clear the trans tunnel.So Osmo oil is worth 100bhp? I'll definitely switch to it!
I've heard some suggest they have only 1 inch clearance between engine and bonnet, so taking 20mm out of it seems to worry them.
For me, it'll probably be challenging for my strut tower brace, but I'll deal with that when I get to it. But generally I don't see a problem.
I’ve just discovered when I went to fit the chain tensioner block how close the drilled and tapped hole edge gets to the gallery in the tensioner block, I reckon it’s within a mm. Just check urs. I hadn’t originally been aware that the tensioner is hydraulic powered and spring assisted.I drilled and tapped a broken bolt to m8, and drilled and tapped one of the oil gallery plugs to 3/8 NPT on my LD28 block.

thanks, I will have a look at that. I also need to check how it works with the KEW twin idler, when the standard tensioner isn't there. Maybe it just sprays out all over the timing cover and chain. or maybe it should be blocked. hmmmI’ve just discovered when I went to fit the chain tensioner block how close the drilled and tapped hole edge gets to the gallery in the tensioner block, I reckon it’s within a mm.

scratch that, the lower idle gear goes where the standard tensioner goes.thanks, I will have a look at that.

Absolutely identical to the Eagle rods I’m using, even the box is the same shape. I’m sure these are all being made in the US and shipped to China for repackagingno danger of me saying anything about anything on faecebook.
Do you have to use expensive american brands to be cool on there?
I’ve got 138mm rods and JE pistons with 27.13 CH, stroke 84.7mm. Assembled I’m at 0.37mm below deck.what length are the Eagle rods, and what CH on your pistons do you have Andrew?
That makes sense, ta. Are you going to skim the block to get it at least flush?I’ve got 138mm rods and JE pistons with 27.13 CH, stroke 84.7mm. Assembled I’m at 0.37mm below deck.
what cc are your chambers?

what diameter are the pistons? are they custom and how much did they cost ? I'm not decided on pistons for my new engine yet - a piston height around 35.5 or so is what I need, and Kameari have that for L28 crank/block & L20 rods, probably about £1000 delivered. But only upto 89.5 diameter it seems, and 90 is a nicer round number.
we have been in touch with Rebello about how they get the ld block out to 90mm+, if they come through with that I'd happily reward them with that.Chambers are 44cc, with a 0.76mm head gasket that’s giving 10.8:1. I considered going higher but general consensus seemed to be this was a good number. I don’t want to skim the block any further as I’ll end having to machine pistons or do more headwork.
Pistons are 88.5mm. If u bought them here in uk they’d be about £150/piston. They were $900 from the states, but they had better info on the valves cutout positions over there.
You could speak to Dave Rebello about your pistons as he’s already building a 3.5 motor, I’m sure he’d sell just pistons.
I imagined you would be going on liners? I wish I’d done this with my LD block, it seems like a great approach with no issues over reliabilitywe have been in touch with Rebello about how they get the ld block out to 90mm+, if they come through with that I'd happily reward them with that.
Yes, that's what we're expecting, but would be good to know a little detail about what Rebello have done - weld it, braze it, cherry on top, anything they're willing to share.I imagined you would be going on liners?
