A 5SFE 2.2 litre conversion any good


Recommended Posts

Effects n/a:

2.0 > 2.2 is a 10% increase in capacity/output. That's the same as adding 1.45psi of boost to a n/a 2.0 (ie, an extra 10% of atmospheric at sea level).

Effects f/i:

Take an ST205 spec 2.0 3SGTE as a base, running stock 10.8psi and go 2.2.....(10.8+14.5 = 25.3psi total) then (25.3psi x0.1 = 2.53psi extra). So that's 10% more power, or the same as adding 2.53psi, ie going from 10.8psi to 13.33psi.

So the options that make sense (increasing in power) are:

1 - fit a 2.0 n/a because it's cheap

2 - fit a 3SGTE because it's "easy"

3 - turn up the boost on the 3SGTE!!!!!!! An extra 2.53psi is the same as going 2.2L.

4 - build a 2.2 3SGTE based thing, but be ready to have to have full aftermarket internals if the 2.2 stuff is weak.

Building a low-boost 2.2 is pointless. If you want to piss about with low boost build a turbo BEAMS, THAT would be worth talking about!
