Compression and racefule adjusteble timing to the max.
Then open up on intake and exhaustside.

But its a nice one

 

J's yellow car has one of their throttle bodies on it. Its not ITB. Their white car was mentioned to have it but the yellow does not.

 

the yellow one jus has the 66mm throttle body on the list

 

when they say the motor is blueprinted...what does that mean?

 

I have heard different opinions on this, and seen different shops take it to different levels, but basically they machine the block to the specs it is *supposed* to be from the factory -- chamfer and de-burr all rough edges, hone the main housings, surface the deck perpendicular to the crank, bore true the cylinders perpendicular to the block, and (using a torque plate) hone the cyinder bores perpendicular to the block. I know that when our cylinders are bored/honed Honda uses a torque plate (very rare for OEM blocks), so the cylinder bores for the F20C and F22C engines should be fine.

All of this can free up a little horsepower, but from my understanding is mainly done for engine longevitiy and reliability, especially in hard racing conditions.

 

can anyone post the specs of the j's s2000 with itb's or post up a link thanks

 

when i went to j's racing, i saw j's most powerful s2000, which makes 320hp and has itb's. The specs are in hyperrev #112, but i can't translate any of it. I'm guessing they've done new mods that are not listed in the article, because they are always tuning their cars and making them faster.

 

the white demo car shown in hyper rev #112 is the one with ITB's. It is using some prototype forged internals etc. These are supposed to be released this year if i recall. I'll ask them about it on my next phone call or email to J's.

 

doesnt j's has 4.77's

 

They don't stick with one gear ratio. They change their gears accordingly to where they're going to race. But they do use 4.77 fd on the touge.
