Small update.
1) Tube frame is being finished up
2) Keeping my ms3, need a higher pressure map sensor
3) Kmiata Bmw trans adapter is on my list the second it comes out. Thinking of the E36 5 speed. Also acquired a 8.8 and some factory five racing axles and monster miata broached hubs from his v8 swap days.
4) What fuel pump do you guys recommend for 500+ hp. I've even seen a couple people running dual pumps.

 

I've got a radium fuel surge tank with a walbro450 if interested.

 

Would I really need a surge tank for mainly a street car? The 450 sounds very appealing!

 

Definitely not, it's a liter in capacity, but an option lol
