    Sorry, pics taken on the run. Deserves an explaniation, huh?

    Quality fasteners and all good parts. Cylinder heads Gen 1 NOS and reman, no cracks. New stainless valves. VF 4 turbo. Times 2. I got three welders and none of them work.

     

    A good bit of welding to do.

  2. Ea- 82 under construction.

     

    Rebuilt. Largest Delta Cams I can get. Don't have these.

     

    1989 SPFI short block, decked .016, so I've been told.

     

    NOS Pink drivers heads. I'm going to hog thease out. .012 cut off deck.

     

    Totally ported, new valves with multi angle valve job. Titanium Retainers and New Genuine Subaru valve springs.

     

    SPFI intake manifold. Weber Carb? 38/38 . Accel Ignition that I have. Full Electronic for carb. Car is wired for SPFI so I can do that when I want. Going to wire the car for twin turbo as well.

     

    Damn, I'm not fond of telling people what I'm going to do. I'll post pictures.

     

    I need to paint the header with VHT. The Ring package fits nice and tight., custom rings from 2 different sets, Japan. These heads will flow excellent CFM when I'm done with them. I've ported 8 sets I believe. Stover Engines.

     

    Steel cam case studs and nuts.

     

    7500 RPM target. Hand polished Valve Rockers Japan HLA. New Genuine Subaru oil pump.

  3. YW. SPFI and Carb block pistons sit flush with the deck of the block. Headgasket is a nominal .060 thick. So, that's .060 piston to head clearance stock. You would be fine lopping .030 off the block. Tightening the quench alone ups the power plus you have higher compression.

     

    Turbo is a bit different. Pistons sit like .017 above the deck so about .043 piston to head. Stock pistons you'd be ok with .025 to .030 piston to head. With a forged piston you'd want .040 piston to head.

     

    But we're talking shaving a carb/spfi block here.

  4. You want to cut any and all wear out of the cylinders. Turbo will blow through any thing less. Hone it and see how it looks. You can get such hones at Auto Zone and such for a deposit, refunded when returned.

     

    It's a real challenge to get a block and all the small passages cleaned out If the bearings go like that. Might ruin all your new work if it's not clean.

     

    Cracked pistons, scored cylinder walls, bearing pollution, not good. The oil pan is sheet metal pieces welded together, your call but some would just replace it as it's hard to clean as well.

     

    You can certainly try though.
