M20 Turbo => M50 turbo fun.

Yup. Bought it. He gave me a wastegate too. It's in super good condition. Yea I have it on Craigslist and one guy is going to buy it if I still have it in 5 days. But he wants it for 300. Whatever. Hopefully someone gets it for 400. It's a damn nice turbo. Best hx40 too. Welded the wastegate shut tonight. And I learned to tig weld!
also, this dude is going to help me make a short runner intake. It's going to be super gnarly. Gonna find a huge throttle body off some gm and put it on there.

Simple, a larger throttle body will let in more air when you push the pedal down the same distance as before. As a result, I have to use a very light foot when driving my car. I found it easier to modulate the throttle when leaving from a stop with an OEM throttle body. If you do want a monster throttle body I think I have a land rover one that you're welcome to. Just pay shipping. I may or may not still have it though... hard to remember.

I stole this from the accufab site;
For instance, the popular 5.0 Ford Mustang typically was equipped with a 60MM throttle body from the factory. This equates to a flow rating of 495 CFM. The Accufab 5.0 Mustang replacement throttle body sizes start with 65MM. The 65MM unit flows 664 CFM. This is a CFM flow increase of 34%. The Accufab bolt on replacement throttle bodies are available with units up to 105MM for the 5.0 Mustang. The 105MM unit will flow 1550 CFM, way more than triple the stock flow rating. Of course, only a serious race engine could even come close to benefiting from that amount of airflow.

I am not sure how this would work with a turbo setup, but on an NA engine you would want to measure the pressure difference across the throttle body. Connect a vac. gauge to a vac. port upstream of the throttle body and take readings at full throttle+high rpm, then repeat with the vac. gauge connected to the manifold (downstream of the TB). I'd imagine you would want to run the smallest throttle body that gives 0 (or virtually 0 ) pressure drop.

Well because I want about 500hp, Well a least this Is what I'm building the intake manifold for, I would roughly want around 1000 cfm right? I don't know. I just looked some stuff up. So I need to find a gm throttle body that flows 1000cfm... I think?

That's even a lot for a stock m50, and they handle boost wayy better.
Sent from the future. Or my phone, who knows.

Going a new direction! Swapping in an m50. Anyone wanna buy a m20 with 128k on it? Also hooked to an auto trans so it was never over revved. Getting a m50 with 135k on it. Hopefully I don't have to replace too much. Too bad I just spent a bunch on money on that damn m20..
