I have a techy question for those who know anything about the F6A engine fitted to my 1997 Japanese import, a 3 cylinder 657 cc engine.

It carries a Romahome camper body and to say it's underpowered is an understatement.!

I originally wanted to fit the Suzuki Cappucino engine and ECU to mine, the engine is identical except for a turbo and fuel injection which almost doubles the power out but these engines and cars are as rare as rocking horse poo.

Fitting an aftermarket EFI system is also quite expensive, knocking on for almost a grand at best.

My other option, is to fit a turbo from something small, like a Fiesta and keep a carb set up increasing the jet size. Looking at the manual, it appears that the jets cannot be changed, or at least there are no part numbers listed for the jets. The automatic choke on the original carb is ropey at best.

So what would be the ideal carb replacement, readily available in the west that i can change jet sizes and would work with this engine and a turbo arrangement?

Any advice welcomed.

While the engines look "identical", the turbo F6A ones are a bit different internally I believe to be able to handle the stress from the turbo. Certainly different cam and ignition timing. Theres a bit more to it than just "bolting on a turbo"

Thank you for the feedback, i had suspected something along these lines, but is there a compromise i can reach where the boost is regulated at a lower level in order to gain some power increase without going too far? I have seen countless video's and topics where people have done just this to a standard engine without any problems. With the engine size i have, and the increased wheel size to improve the handling, i am foot to the floor at just under 50 mph with crippling fuel economy. Even an extra 10+ BHP would solve most of these issues. I could bite the bullet and fit the F13A engine, the 1.3L but i love this quirky little engine.

if you're sensible, sure it can be done. Just remember longevity will be reduced and it will require a bit of specialised knowledge to get mixtures and timing right as Turbo engines can be prone to detonation if ignition timings not correct. I'd see if you can find a specialist in the area that does turbo conversions, lots of the race guys love a challenge like this.

As far as the carburetor goes, jets are easily drilled .
A common issue with motorcycles.

Turbo fun!!
Do it!!
