Figured I would introduce myself

400whp + E30 = death.

False.

[iamsam]

its true, M20s are great for turbos.

400whp + E30 = death.

haha, 400 whp + E30 = no chance of having a decent autocross car.

I kinda figured I could get 300 whp and have a car that is fully boosted by like 3k on a smaller turbo. Ideally it would be boosted enough to be fast as fuck, not boosted too much such that there is no chance to get traction at low speeds, and a small enough turbo to get boost FAST! I'm only thinking like 8 psi, but this is all from what I have read and researched. So, I might be way off.

Bottom line, its going to be a partial DD that kicks ass at autocross and possible track.

TCD uses old turbo tech, but uses ~14psi to get 300whp.

What you need for a good autox turbo M20 is a slight cam (schrick or VAC might have an M20 turbo cam), wiiiiiiiiide tires, and a good suspension setup.

400whp is totally doable, if you have the tires to put it down. Turboing an M20 bumps you into SM class at a minimum, so wide flares, 18x10s or 15x10s, 285/18 or 275/15, and a wicked suspension setup are needed to be competitive. M30 will be better power on boost, but heavier, so not a good SM motor. LS1 would be insane, and lighter than an M20 + turbo option......but you'd be in XP.

If you just want to have fun though.....don't worry about classing and just do what you want.

Autocross is for noobs

Yah, I figure there is no chance to be competitive in SM especially with Chris Mayfield driving that fucking insane evo. Have you seen the video of his national championship runs....you know the ones where he won SM!!!!!

That shit is insane!

[MisterMiniS]

I figure I will keep it in DS or something of the like until I turbo it. Then, I will just be in SM, but not competitive. Who knows.

[hyperE30]

if the m42 is done right and all the right parts which they are very pricey!!!! it could do 400+hp.. but if you build a eta bottom with an i head the right way it can do 300+hp easily.. proven many times..overall both engines are great(m42.. m20)

Mistermini - Welcome to the club.
I am currently sitting on 3 e30s and would/should let one go -86,88, and 89
Let me know if you are coming up to the mountains anytime soon.

[MisterMiniS]

Will do! It's ski/snowboard season!!!!!!!!

[bcausey]

Will do! It's ski/snowboard season!!!!!!!!

Indeed it is...

[Bishop]

I think bcausey was saying he's got 3 e30s that he might be willing to part with Mini....
