Kamotors E30-Turbo to ITB M20

[ThatOneEuroE30]

I'll be running the e28 lower as my E34 lower was cut to fit the stock E30 rad, and the lower ports sits further down on an e28 rad.

I hope it all works I wanna see this thing shred tires!!

also don't remove the thermostat, the M30 cooling system doesn't work properly without it, you won't be forcing water through the radiator and will just make the cooling problem worse.

overboosting fixed

with no other changes besides adding around 2 feet of exhaust it now sits a at a solid 13.5-14psi of boost at WOT in any gear. My exhaust was total around 18" previously

Why would the exhaust lenght cause overboosting?

Oh that's will make a difference for sure. How do you plan on finishing of the rest of the exhaust?

[RagtopE30]

Because with the lack of back pressure from the longer exhaust the path of least resistance was through the turbo regardless of the wastegate

[kamotors]

More bends=slightly more restrictive, so now more exhaust can escape via the wg(path with less resistance). Similar problems happen with wrxs when they goto a 4" down pipe.

quick video, kinda slow still but its getting there, this is at 13.5psi and missing a lot of ignition timing.

I would cut out all the plastic between the grill slats if i was you. That is a lot of frontal surface area that could be airflow to your rad. I did it to the euro grills on my car.

Yesss that's so sick. Good job. I really need to finish mine so i can turbo it haha

[MPLFoster]

nice

[golde30]

Sounds like a beast. Can't wait to see some tire consuming once the new setup is all tuned.
