is it possible? Does it bolt right on with no modification? What kind of results are expected?

 

This is something I would want to do, I would have to get a electronic fuel controller and a wideband.

But does it give any gain?

This would be cool to do when I go megasquirt 2(i am waiting so I don't have to convert to distrib)

does anyone have more info

Maybe if I get my hands on one I could make a aparter plate

but is it worth it?

 

no bumps allowed in here..


What will happen? you'll gain 95 rwhp and a more steady sex life.


To my knowledge it won't bolt up, and it would more than likely be too big and actually cause a loss in driveability and power unless is on some crazy ported motor.......but I dunno.

might have better luck nd a more definitive answer in the 20B section.....

 

As far as I know, the throttle body isn't exactly a system bottleneck. There are much smaller areas in the intake assembly.

 

Um, why would you need that for a mild increase in TB flow?

You mean adapter plate? That would defeat the point of using a bigger TB. If the three holes in the UIM are still the same size you will get zero benefit.

This is nowhere near a bolt-on job. It would require significant modification to the UIM to be of any real benefit, and then the benefit would be minor.

The 20B TB is the same size as the 13B-REW TB. Can you explain why this TB could cause a loss in drivability and power if you managed to fit it to a 13BT when it works fine on a 13B-REW? Coz your guess makes no sense.

 

I thought the REW had slightly bigger intake ports than a regular 13BT? (Well I know the 13BRE does for sure...)

 

yea the rew has bigger ports than the 13bt..

 

so I didn't check my spelling

And I had no idea that it was the same size as the rew tb, that was what I was asking. I thought it might have been bigger.

 

No, it doesn't swap and bolt right in.

I guessed wrong, thanks for pointing it out so eliquently.................

I know the rule about assumptions, and WHOOPS I figured an engine with an extra 650cc's might have a bigger throttle body, which may cause bogging at lower throttle inputs due to the OVER-sizing. Now I've never had a 20B TB on my FC no.......but Ive had other, LARGER, (mustang) TB's on my N/A when I was mucking around and found that too large means its hard to drive...WOT was fu as hell, but puttering around was difficult....now....

You seem to be baking up the fact that it is a larger TB, so tell me why it wouldn't cause any lack of drivability at all? which is what your post is suggesting.

 

Because the primary throttle is still 45mm (same as FC), and that's what you use for most low-load driving. With the 50mm secondary throttles added it's only 15% bigger overall, and I can't see that causing any problem. And like I said, the 13B-REW has no trouble with this TB, and neither has anyone with an FD UIM/TB on an FC.

 

ahhh makes sense......now you got me

 

thanks for the help
