Question How much boost can I run?

Hello I'm quite new to this forum so excuse me if I sound like a noobie. I recently pieced together a T25 turbo kit from various sources for my 1991 miata (with 145k on it). I am running it with no intercooler or ecu, but with a economical supplement - a FMU (vortech) and a MSD ignition box. I plan on achieving around 4-6psi now is that possible given those parameters?

There's this magical thing in the top right of your screen called a "search bar."

Beware: the magical thing's magical powers may overwhelm you with great knowledge.

In case you didn't know, you're about to get seriously made fun of.

Simple answer: probably.

Slightly more verbose answer: I personally could not imagine tuning any forced-induction engine without a wideband O2 sensor, but then I do remember a time when men were men, sheep were scared, and wideband sensors were the exclusive playthings of OEMs and the very rich.

so a piggyback or standalone ecu would have to suffice?

Raise fuel pressure to 100psi, set static timing to 6 degrees, disconnect actuator hose.

OP this guy has a truck engine just like your B6, and he runs 150PSI, so I'd run at least 75PSI or you are a *****.

You can run as much PSI as the turbo is capable of running.












Once.

If this was my car and I wanted to run ALLOFIT, I'd kill myself for running bandaids and no intercooler.

Says the guy currently running only the wastegate on an EFR.

14.7 psi... absolute

at least until you get some proper fuel management, then you can explore above atmospheric pressure.

C'mon, you queers. It ain't that bad. The RRFPR and MSD "Sebring" box may not be cutting edge, but they were mainstream fuel and ignition management for a number of years.

Stop scaring the new guy.
