Nice build! Like the work your putting into the engine!

Also did you use the stock pistons or aftermarket?

internally the motor is all stock. just cleaned the s*** out of everything, fresh rod and main bearings , crank micropolish , sanded down and polished the piston tops. block decked heads milled and a valve job.

Where are you planning on putting the turbo?

Looking like it's going to be one hell of a ride.

What valve work did you get done?

Love the build so far. The manifolds look pretty cool.

also to answer your fuel question. 1200cc bosch ev14's twin aeromotive 340lph pumps single 5/8" feed "10an" split into 10an to 8an y block, then the rails then a1000 10an FPR and back to the tank with a single 1/2" "8an" return

I was wondering how to fit at least a single turbo in the bay..you think a similar setup for duals would work? with one smaller turbo in each corner? I'm using a custom manifold so that would make plumbing easier i'd hope... also, what engine management you using?

Excellent work. What is your educational / work background? Looks like you have previous experience building engines.

i've worked in a couple shops just going oil changes and s*** like 10 years ago lol. but i just have a really high mechanical aptitude. i've built and tuned alot of turbo honda's before i got this 240. but other then that i just like to learn from doing, nothing like good old hands on experiance!

well this was the only way i could think to do it short of relocating the radiator like jeff taylor did. and i can't think of any reason why you couldn't run twins with one in each corner. i'm going to be using a 1010 aem ems just like jeff taylor used on his. cause really if you plan on throwing boost at this motor you would spend allmost as much on getting a bigger maf and the stuff you need to chip the stock ecu as you would just buying a used honda ems and adapting it.

Ohh, pretty. I'm currently in the process of re-doing a VH swap into an FB Rx7. What size piping are you using? Seems to be fairly large stuff. I'm constructing a log stle header currently using 1 3/4" runners into a 2.5" log. Looks similiar sizing to me.

basicly yeah , its 1.5" schedule 10 for the runners and then collects into 2" schedule 10

Nice build. Can you tell me if you still have original oil filter Bracket locator that bolts into the pump what direction the oil flows. ie the top hole flows through the center of the oil filter or vise versa. I see you to have done a relocation for the filter and your help would be great. \
thanks

i want to say that all oil filters flow the oil into the outside part then out of the center hole back into the motor, i'll have to check later to confirm that.

More info on "oil crap" please. Did you remove the plugs from the side of the block or make an adapter to replace the factory oil filter tree?

little more progress. got the manifolds all welded up and only have to fab up the wastegate portion .
i pretty much trashed the stock fuel hat trying to figure out a way to fit 3 -8an fittings on it, so i dumped it and picked up a q45 fuel hat and that worked a million times better.

oil system is done also.. just have to make the mounting bracket for the filter housing
Image
Image

so basicly where i'm at now is bracing the turbo side manifold , mocking up the wastegate , whole lot of wiring , and probly a bunch of other misc crap i'm forgetting about. but thats the bulk of it.
