Subaru STi Block Honing

A Subaru STi block being honed on the Sunnen CV-616 by John Edwards @ Costa Mesa R&D Automotive Machine for a set of Wiseco forged pistons. The engine will receive a GT45 turbocharger to increase performance. www.engine-machining.com (949) 631-6376

If you are honing a block, doesnt the honing takes some metal of the inside of the cilinder casing? And does the piston still works properly?

I mean, if you use the same piston from the old block and put it in a honed block, dont you have space between the piston and the inside wall of the cilinder casing?

And does it increases the enginevolume?

@eddohan - 2 things, you hone to take the bore oversize, or you hone for effect. Honing oversize removes a specific amount of material that requires new pistons to fit properly and it does increase displacement. Honing for effect generally involves removing about .001" of material to enable the rings to seat and work properly so there not measurable increase in displacement.

Do you offer torque plate honing for models such as D16A^,SR20,4AGE, and EJ25~, ?

[fiatnutz]

@station2station - Yes.

[ithollywood32]

whats the price of doing this?

[fiatnutz]

Honing a 4-cylinder runs around $140

You're a nice guy sir.

But relax, go have a time on a trip or something, and get some sleep ;)

Thanks for making so much videos for us though :)

@gc8impreza98 bro are you really thinking of running that much HP with that turbo??

[compucar03]

What do you think about boring and honing this engine on a bridgeport? Should work ok? I have one in my garage and was thinking about just lining it up with a co ax indicator and going .010-.020 over on a junked motor.

another big question since you do a lot of blocks, WHAT ARE THE OEM CYL WALLS rated at for the o6 sti USDM model, i'm trying to take all those facts into consideration since the gt4088r i have can produce 700 plus whp with the right mods, some people tell me not to do the sleeves other tell me is the best way to build a block, please let me know THANKS

[GC8Impreza98]

06 sti with a gt4088r just pulled motor out to do the build the right way to support that turbo since i was luckily running on oem pistons and rings,i need to do some good pistons and rods, which brings me to my question, should i do a bigger displacement on the block, like BOre or will i run good if i use some STD JE PISTONS with their JSP skirts,im building the whole bottom end and any advice from you will be greatly appreciated since i seen you do such great work, don't sleep is a waste

that VW block sure is Good.

@zolja95 Its a lubricating oil, not leaking.

[jjk1224]

Thats some yummy looking oil!

[zolja95]

@Bones12x2 tnx mate :)

[yohpaulus]

is he stoned???

@zolja95

Its for lubrication to prevent damage
