Hi Guys
I have an Indian built 2003 Suzuki Alto with a 1061cc Sohc 16 valve Maruti F10D engine with 64bhp,
It will never be quick but is there anyway I can pep it up a bit?
I know a bit about tuning older engines port matching fitting larger carbs freeflow air filters etc
Do these things still help on newer engines?
Would a larger throttle body and freeflow filter make any difference?
Three angle valve seats?
Port matching?
Its also got 2 catalytic converters would removing one release any more power? (I know emissions at mot time might be a problem)
Thanks
Adrian
P.s It will need a new clutch soon would it be worth skimming the flywheel before fitting a new clutch?

nitrous!!
change the camshafts for wilder ones.
feed it some boost, none of the things you mention will make a noticeable difference.

i think that you mind find it cheaper and quicker if you drop a motorbike engine in it. busa or big zzr or ye olde black bird or gixer or something?
maybe something to think about?

Tbh i think you would struggle doing conventional stuff - time and money over any potential power increase , unless you come across something very obvious llike a very restrictive inlet manifold .
Either way its going to be a lot of work , if your going to have to take the thing apart anyway then turbo charging it may be the way forward .
Really depends how much work you want to do - either way its going to be a hell of a lot of work so maybe just a bigger engine from another model would be better .

all the stuff that works on bigger engines will work on yours , its just all the time and money might yeild 10% increase which will be next to nothing
bigger engine from a sporty model or strip out excess weight

I'm building an F10D Alto myself just now.
I didnt even consider anything except turbocharging. Ive gutted the first cat, taken out the 2nd cat and neither made much if any difference.
Theres a few other tricks you can do to make them drive better though which i can explain when i finally start a build thread

paint a red stripe down the side thats good for 10bhp....(At least)
joking aside....Id say weight reduction on a small engined car like you have would make more sense than spending hours port matching manifolds and stuff.

Port matching made a big improvement to iron head Siamese port pushrod engines, yours is 16v and presumably aluminium..
Perhaps get all the turbo parts from one of those Mercedes Smart cars at a breakers, and if you're on a budget just do single blow through carburettor, then the only new ground to break from a fabrication / design perspective would be a boost referenced ignition retard system, probably Megajolt-Lite or whatever it's called these days. lol

I recently converted a 1600 engine from fuel injection to CBR1000 carbs and ran it on megajolt. With supporting modifications the engine made 150bhp much to my surprise. Turns of the I let was incredibly restrictive to made the vehicle adhere to the emissions regulations implemented at the time.
Perhaps getting rid of the ignition system, converting it to bike carbs, megajolt or nodiz and combining it with a decent exhaust may provide some respectable results.
My megajolt cost me £200, carbs £100, manifold was home made. So with mapping and misc parts it was a sub £500 job.

Take a first generation Ford Zetec 1.6 and compare it to the 1.6 TU5J4 engine seems in the Saxo VTS and Pug 106 GTi. The latter responds to breathing mods very very well in comparsion. If I am honest the 106 engine packs more of a punch compared to even the XU5 engine that's in the 205 GTi. |

Made a turbo manifold for my f10d
Sorry to drag up an old thread (2 years ago, wow)
I've got an F10D that I'm swapping into a japanese suzuki carry truck, replacing the original and gutless F6A three-pot.
I'm currently running it N/A, but having seen your turbo setup I'm wondering what supporting mods are required for this? are you running standalone or the stock F10 ECU? any light you can shed on this would be great! top work BTW
