I have already bored the stock throttle body to 64mm from the stock 60mm and installed a new brass plate. I see no need to buy a new throttle body for a 2-4mm larger bore. The main reason for this is cost. I have less than $70 in parts so far and I would like to keep it that way. The inside of the runnersis radiused so I do not think that I will see any greater flow gains unless I spend $40 a piece for velocity stacks.

This is how the plenum floor looks.







I think that this a superior design to those with velocity stacks for turbocharged cars. Companies like virtual works have smooth entry runners that out flow veilside velocity stack runners by almost 30%. The velocity stacks cause turbulance which disrupts the air flow.

Enough teaser pics. I am finally done.

Too clean for HMT. You could've at least JBwelded the vacuum ports. Nice work bro. Now, you just gotta figure out a price and sell them bitches on H-T.

How does $500 sound?

I think you would sell them like hotcakes. There are also some accord/prelude specific forums that would go for it. Even more so if you got some dyno numbers.

I would like to get some flowbench testing to compare stock and the custom intake manifolds before I put it on the car to tune. But I will have to find a flowbench first.

wow I have been contemplating doing a manifold for the b20 in my 89 lude and that is just too nice, kudos on the work and hope it performs the way you anticipate it to

I will be flow bench testing it along with real world testing is as soon as my motor gets put back together.
