Building HF block

so i got a spare HF block lying around, its already stripped and in decent condition, no cracks, etc... i also have a spare y8 head kicking around. anyways i was thinking about building it up, using the block filling method posted on the sticky to reinforce the block, but im worried about the rods, the're like ------- toothpicks, anyone know what crank/rods/pistons will fit in there? ima try and buiild it with the lowest lowballer budget possible. thanks

Re: Building HF block

just use it stock or dump it
if its not at least 1.6l then its not worth building or filling or any of that ----

Re: Building HF block

well lets see thats the only engine that i dont knwo about as far as internals but the only difference i can see between that d15 and the others is the cylinder head. you could probably use the d16 pistons cause it has the same bore as the d15s (75) and a cr of 9.2:1(d16a6); 9.4:1(d16y5/7); 9.6:1(d16y

. other then that you would have to probably use any d15b rods/pistons soo look it up there isnt many piston/rod combos that will fit in there rods would have to stay d15 because the next one closets to it in the d family is the d16 rods with have a larger stroke 84.5--->90 and rod length of 134mm----->137mm. that is of course if the d16 piston will fit on a d15 rod or vise versa.

Only HF or D13/D14 rods will work with the HF crank. I'm not sure, but don't think the other D15 cranks will fit either.

Re: Building HF block

I suggest selling or trading for something that takes less work like a d15/16 they are dirt cheap.

Re: Building HF block

the most productive thing you can do with it is save it for a replacement engine if you ever kill the one that's already in your car. atleast you'll be able to get around during the down time.
