Individual Runner ?'s

[Doubt_Incarnate]

progress is slow. i've never seen anything have this hard a time cutting through pine. maybe my bit is to slow. or to coarse. it riped chunks out of my practice peice. aniahilated it. i did do some grinding to slim down a couple of valves. i'll be putting my progress on my page. click the "experiments" link

I'd suggest having the flanges, or adapters as you call them, laser cut by someone. They will look a lot cleaner, and will nto warp due to plasma cutting, and will be a lot more accurate and clean. Sure it is another $100, but IMO it is well worth it.

You can just send them a gasket and they will make you a flange, it's pretty easy.

the pushrod motors are differnt from the tdc motor. they messed up on the heads. the part im trying to make will replace part of the lower intake that goes under the valve cover, covers the pushrods. these heads are like 80% of a normal head, on my 318, and the 302, the pushrods went through the head, like everything else. but not these, they didnt feel like finishing the job i guess. i'll take your advice on the flanges, but i'm pretty sure these adapters need to be machined out.

my drill pres didnt make a good "mill", it had a cheap plastic peice that fell off, and kept falling off. i'm going to pick up a router table next week and try again.

I love seeing ideas like this. Here is a pic of a ITB setup I am fooling around with...

that looks cool, but is it really dual tb's? if all else fails i'll do a similar thing with short stack adapters like that. really like to make a one-off manifold, but its gona take quite some time. maybe even try for a "variable length runners" setup. right now i wish there was a machine shop nearby that did custom stuff, things would go a lot faster.

That was the origional plan but now I would really like to do an ITB setup.

i was thinking about doing this, but my plan was take 3 or 4 inch tube cut it in half, add a piece of sheet metal in the center, making an oval type shape, and having the runners come out the side and use like an LT1 TB. basically same idea as the TPI intake manifold.

That is similar to one of my other ideas.

I have come up with so many different plans/configurations for my 3400 swap in the Fiero. The origional plan was dual TBs with short runners and a stock Buick GN turbo.

Then I bought a 300ZX TT and the project was put on the back burner, actually all the ingredients were put back in the cupboard...

Then I had the crazy idea of putting a Z TT engine with a Maxima 6-speed in there but I decided the weight/cost/headache was not worth it.

Then I started thinking of just putting the 3400 in the car stock.

Then I went back to the GN turbo idea.

Now I am planning on building an 11.0:1 ITB 3400 to keep weight/headache to a minimum and have a nice potent NA Fiero.

Here is the mock up for my 300ZX ITB intake. I know this is a GM forum but I am just posting these to give people some ideas. It is a 60 degree V6 afterall

? why not ?

what about raising the stock upper intake to get more intake volume

If you want to keep it under the hood, you only have ~1" to work with, and going with 1" makes the plenum hit the hood when its closed.

RE: Re: ? why not ?

As the TB's are sitting in those pics they are already too high. I need to trim som more off the center portion (manifold) so the TB's can sit lower, almost on the cam covers.
