M20 Turbo => M50 turbo fun.

Head welded?

A lot of m20 guys weld some of the coolant passages or whatever. There are some that are just worthless, and it creates a better seal or something. It's like super good and it's not going to cost me much.

[Rowleym]

Hopefully buying a hx35, intercooler, and a oil cooler. Oh, and a fuel filter and cone filter thrown in.

If the oil cooler doesn't work out I have an earls one on the shelf I'll probabally never use.

Why is that?

[240sxguy]

I don't need it and am too lazy/cheap to plumb it into my 240sx.

I'll be in GL for thanksgiving You gunna be home? I'm putting some big mudflaps on the E28 so I can prevent rust

. I'll stop by regardless

[Rowleym]

Well I will be around. Hopefully available though. I have to write a 24 page essay on diet affecting adhd in teens, make a children's book for Spanish 5, and apply to a college. It's going to blow. And after that, I want to paint the e30. Well and pull the engine/trans because the clutch is coming.

[Rowleym]

Buying the intercooler, turbo, oil cooler, fuel filter. And cone filter right now. All I need is like block stuff like gaskets and bolts and flywheel surfacing and shit and I'm done. Oh, and down pipe to nothingness haha

[Rowleym]

Anyone need a "super" hx40? It flows 69lb/minute. 400$ obo great shape!

[240sxguy]

Put it on craigslist, it wouldn't surprise me if someone grabbed it to upgrade an older cummins or some shit like that. Did you buy that HX35 yet?

[Rowleym]

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.

[Rowleym]

12cm exhaust housing on it by the way. That's gonna be perfect for drifting I think.

[240sxguy]

Run the smallest throttle body that will support your power goals, I have a 90mm on my car and I would prefer that I didn't. It was much easier and better to drive with the stocker.

[Rowleym]

Thanks for the input. I'll research that momentarily. I didn't have a clue it would affect driveability. What exactly is affected?

[240sxguy]

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.

[Brian.]

I could take it up to him, he lives in the town where my shop is.

[Rowleym]

Got my flywheel resurfaced. Getting my head welded this week for 200$. Woohoo!

[Brian.]

I lied. I left already

[Rowleym]

I tried reading up on throttle bodies. I want to build the short runner with capabilities of 500hp. Any recommendations on throttle body size?

[240sxguy]

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.
