I have been warned by several members here against using TWM itb's for my 96 Prelude.

I contacted Jenvey. They do not carry anything for the H22. Jenvey recommended, Chadil. They make itb's for the H22.

Have you heard of them? Opinions please...

Jenvey told me that if I can get this manifold (bottom left):




Jenvey can supply some TB throttle bodies to fit.

 

whats the price on that manifold??

Why is TWM so bad? just price?

I don't own them, so this isn't first hand experience, but I always read about people having problems with the throttle sticking and issues with the vacuum system.

 

thats a pretty cool, that little adapter manifold. If someone made an adapter to make like 954RR throttle bodies bolt up.....they would probably be a rich man, very cool

From personal experience, I know the throttles like to stick open. An easy fix is to add a third return spring going the opposite direction at the driver's side strut tower.

And the vacuum system isn't the greatest, you have to drill and tap each runner and run to a vacuum log in order to get a somewhat constant MAP reading, like so:

I was shocked by some of the PM's I got about TWM's. ****...even somebody who sells them doesn't recommend them (not on this forum)!

Basically, throttle sticking issues and vacuum issues.

hell ******* yeah...how much for them and what is the turnaround time?
also how much are the jenvy tb's and velocity stacks?
they also make their own tb"s also...might be cheaper
site looks good but currency is in euros

^ I sent Chadil an email and am waiting for a reply.

The only reason I am considering this is becasue Simon at Jenvey strongly recommended Chadil.

 

interesting, maybe we could get a group buy on those flanges? I'd be up for at least one.

 

Those manifolds are for DCOE TB's or carbs. They are also made to allow a maximum ID of 48mm.

Not worth messing with

So what? No reason you can't port it out right? It wouldn't be that hard to design your throttle body around their bolt pattern or even make an adapter for an existing one. Its alot of work to machine a flange like that and if it could be had for a few hundred even, it would be well worth it. (to me at least)

 

looks like a good idea,
will allso reduce the intake temps.

i thought the same exact thing.

 

in for more info

 

Under accessory's on the Jenvey site it show's adaptors for Weber type to SF type TB's . Just ask Simon, he can sort out what ever you need.
