so an efi turbo 800cc is looking more likely by the second.


Some of the Cappucino chaps used to get impressive numbers with an F8B (yes, B) block out of an 800cc Hatch (3 cyl, 797cc) and using the Turbo F6A head with a Cappucino F6A sump.

Just as a comparison, the F5A twin-cam Turbo makes approx the same power as a F10A (but at higher revs and with less torque), and F6A twin-cam Turbo makes about the same power as a G13A (but at higher revs and with less torque), so you could expect that a F8B with a twin-cam head with turbo and correctly set up with larger injectors and re-mapped ECU could get the same power figures as a G16A. You wouldn't get the torque figures of a G16A, but at least as good and possibly better torque than the F8A.

F8B bellhousing bolt pattern (and clutch/flywheel) is the same as F8A and F10A. F5A and F6A bolt patterns are slightly different. You would need a Jimny/Sierra pattern sump from the F6A rather than the Cappucino sump.

F8B blocks were only ever 6 valve heads, so you might need flycuts on the piston crowns to clear the valves of a 12 valve head, or just double up on head gaskets to keep the CR down.


8) I had wandered if that would work!

Do you reckon the head from an F6b would fit on an F8a? That'd be a nice combo. 8)

You're going to love that motor. Sort the gearbox and you are laughing.

make sure you get the acelerator pedal as it has a kick down switch on it ( yes even its a manual) Must be like an extra fuel cut in super turbo boost button type thing.

It *might* be a WOT switch that ups boost slightly when at WOT with the airconditioning on.

My Cappuccino made 8psi stock and 11 psi at WOT with the AC on.

It's irrelevant if you use a boost bleed. Greg's ran a bleed and made 11psi all day with the bleed fully closed.

The turbo is so small that more than 11 psi is pointless. Try for more and boost will spike over 1 bar on a transient and hit the fuel cut, and if you defeat that you'll find the turbo runs scaldingly hot in any case.

Really, they need a bigger turbo if 11psi of boost on a stock turbo isn't enough.

I am surprised that people say that a cappacino goes well, I have had the misfortune of driving one (yes it was a squeeze) and thought it was ordinary. What KW are they supposed to make maybe I drve a dud??

Tell me more please :D . Is it an IHI RHB31/32 unit? When do you start seeing boost on the 660?

RHB31 from memory.

Torque is not legislated in the Kei Class, only HP, so the turbo is sized to provide boost as low as feasible (about 2800rpm) but that means that once your above about 6500rpm the turbo is out of flow. The result is a slightly doughy feel above those revs.

In a Cap motor, boost actually falls above about 7500 rpm.

The bolt on solution is a high flow version of the IHI turbo form Suzuki Sport, (Japan) the "small" turbo from a twin turbo (B4) Liberty, or one of the CT20 turbos from an 1GGTE toyota. Manifolds will be required for anything except the suzuki sport turbo. They will all raise the boost threshold, effectively resulting in a narrower power band.

Remember the whole point is torque and the restrictive manifolds, tiny turbo etc make sense.

Stuff to consider.

Sweet! Cheers for the info its actually for my other project. I'm going to use an RHB31 with ~285cc that revs to 10k. It should boost descently :P
