I'll have to remember these mods for the 7A-GE I want to build. Speaking of oiling and mods, would it be worthwhile to smooth out or polish the inner section of the block behind where the oil filter sits? And to radius that hole where the oil flows out and into the filter? without a doubt.... radii...

Looking forward to this build, please post as many details as possible, also about the block assembly, would be nice to have a good build tread about a 7AGE, as I am going to build one for my car :dodgy: Will you be using a 4AGE Oil pump? yes... with a few minor modifications (more later) and now i...

Epoxy instead of paint? Have you heard of ceramic coating a block, for shedding heat? I was talking to someone at a shop who has ceramic coated parts for me, was getting some ideas. I was thinking about ceramic coating the 4A block that I've been using as a guinea pig (smoothing out the inside cast...

What is the advantage of the MRP's wet sump, compared to a normal AE86 sump? 3 distinct advantages: 1) Volume... the MRP pan holds 5 quarts, the largest stock pan holds 4, and some 4AG pans holds only 3.5. 2) built in windage tray as well as baffles/trap doors to keep oil around the pick up. 3) ext...

Nice! And what about the crank shaft? Will that be MRP or 2ZZ? to remain 7A... Back in February I was contacted to build an engine for an N2 Levin replica being built in America. The client was not looking for all out power, but they did want a big valve 7AGE. About a week ago this arrived..... htt...

I suspect a lot of work going into the head for this one. Big cams and valves. Replacement of the valve seats to accommodate the new valves? This head will be similar to OST-043, so yes... a great deal of work - beginning with new valve seats. So then the owner will retain the stock internals of th...

more to come.......

Were the other cyls clean & dry & smegma free? Is there going to be any more finishing/grinding the comb chamber, all the area after the 45, on the 60 to 90 and the ridge around the seat? dry for the most part, but far from free of build up.... no more work in the chambers... Blending the a...

Do you have a print out of the dyno??

I have a few rebuildable cores... any interest in a fully rebuilt - ported head?

As it says in the title. Looking for a crankshaft in good condition and one that has not been cut to use oversized bearings.

Do you know which largeport head it is??

looks like you got the tube header... good score over the factory log.... BUT check clearance... the one I acquired was too tight to the radiator

Wow, that's a new one! If the guide's top isn't normally submerged, extra seal or no seal shouldn't oil it up that much, besides it's only 1 exhaust & isn't going to affect the other or the chamber. Burr on. bothered client....... So what's the plan for this engine overall? The plan... the bott...

Just make sure you get a mineral oil without any friction reducing additives . Oils with friction reducing additives and synthetic oils impede the bedding in process and should only be used after running-in has been completed. Cheers... jondee86 I've used "Driven BR30", and recommend it t...

Those domes are pretty shallow... estimated to be 13cc... Actually... they were 10cc, so static CR on the 5V is(was) under 9:1.... :( Thank you Traum Piston - With their help, this is what my 5V will be running..... instead of 10cc, this piston has a 21cc dome http://ost.ebeans.ch/albums/userpics/1...
