If only it was an lsx it would make twice the power of a k20...
Problem is the whole swap is 5x the cost of this swap after all the details.
A usdm k20 with just itbs and a header wont make enough to be worth the work.

So my itbs don't have any velocity stacks and I wasn't to worried about it until my neon buddy showed me this thread.
www.neons.org • View topic - Runner Length Tuning...ITB style
That is alot of cheap power and a huge amount under the curve that I'm leaving on the table.
I'll copy cat this test after I do the head work to settle on a proper size stack but damn am I ever excited to try it out and see what taking full advantage of the throttles can do

So ~10" was my personal favorite.
Also short runners = le suck unless you're doing nothing but drag racing.
Too long though and you start dropping off up top.
Wasn't it already kinda discussed here too though? I'm sure its in one of the manifold threads. Basically you want something like 9" or something like that iirc

After watching Emilio's Crusher I want 180whp like a ************
A turbo will **** up my classing, I'll have to jump up to play with the 300zx fiber body L28 racecars and crap like that :/
This setup keeps me with old E30 m-swaps, swapped civics and the like, things that don't blow my **** away.

Cant wait to look at the vids of this when I get off my phone and onto a computer. Just wanted to mention that ITB's change the design of intake runners a little because you have the runner length pre-TB and post-TB. So you have 2 variables to play with.
I've looked into it a bit and it got awful confusing, awful fast. Maybe with a bit of experimenting you can shed some light on it for us.

Then, I forgot everything I had read; cut my manifold where it lined up with the throttles I had and put them on the car and drove it.
Its a good motor for the miata, if you have the means its a very straight forward swap, biggest issue is the oilpan construction.
