Theoretically 50% increase in power. Probably over 100 hp. You can safely use stock hyper-eutectic pistons then, but you really do need a good ignition retard. If blow through, you will need a variable pressure fuel pump to push fuel into the carb against the boost and you can use an inter cooler although for 8 PSI you won't gain all that much. EFI isn't a simple as that. These systems are simple and can't supply much more than stock displacement requirements. A 1.5 liter at 8 PSI will 'look' like a 2.3 liter engine for fuel needs.


So as far as getting enough fuel to efi, I need a strong fuel pump, and injector(s) able to push enough fuel so that the mass air flow sensor can tell the CPU to dump
More gas as the RPM's increase and the turbo spools?? Or is that not a correct assumption?

I'm expecting 7-8 pounds of boost.

If you are really serious, this is going to cost you money and more research. I think you better do your research first. You can't run an intercooler with a draw through set up. You're going to need forged pistons if expecting to boost over 10 PSI. Stock pistons are good for about 8 pounds of boost. I would hold off on the H-190 or 8.8 because the engine won't last long enough to matter.


That's why I came here, so I'd know what I'm getting into, and have a starting point for my research. I may do a blow thru, which one is likely to make More power? Draw thru is easier to tune with carburetors right? And with efi, either draw thru or blow thru is equally difficult/easy?

Mocking up for an intercooler the other day, it's on jackstands now waiting for the trans mount, driveshaft and a few lose ends.

*young guy disclaimer* "because I have it" isn't the reason I'm doing it this way. "Because I want to blow big motors out of the water with a tin can car and rubber band motor" is the reason I'm doing it this way
