ITB...

Hmm what if I was using a transmission adapter plate and pushing the motor forward slightly as a result?

Why do you need an adapter? Are you using a t5, th350 or 400 trans? The 3500 bolts right to the v6 RWD trans.

I cut and rotated the coolant neck to tuck it in along side the passenger side head.

How did that help? There's only about .5" from the manifold to the firewall, rotating it won't make it any thinner.

I tried fitting a FWD manifold with the t-stat in the rear and the manifold itself fits, but the coolant neck won't without firewall modifications.

A little off-topic, but could an equinox plenum be used with a rwd setup to allow use of the fwd accessories and timing cover? Makes it easier to run an external trigger IMO.
Is there enough room behind the engine to keep the thermostat housing at the rear of the engine? (in 3rd-gen F-body)

if you're having clearance issues... why not try an equinox plenum? It's basically the same as a 3500 just with the TB up top.

if I could get one locally, I would give one a try, but they are just so ugly...

Wouldn't you have to build some sort of custom plenum to run boost anyway? (or run 6 pipes from the intercooler...)

one half of me really wants to make this happen, the other half knows I shouldn't....

I've seen superdaves, it rocks!

I think the triumph TB's are 45mm, but I do not have confirmation on that yet.

Yeah, I like what he did as well with the ITB's. I quietly observed his posted progress, truly a fantastic engineering accomplishment!

This thread seems to suggest that I would need a 35mm itb setup...

[ericjon262]

well that say's 54mm, but doesn't factor in rpm or power levels, so I don't know how well to trust it.

how about this one...

thanks for posting that! thats pretty cool! what size TB's do you guys think I should shoot for?

His TB's were 48mm, his engine displaces .75l/cylinder.

mine is a 3.5 and displaces .58l/cylinder.

I'm thinking about 42mm would be ideal....

read my build thread, nothing is a bolt on, until I make it!
