Tuning increase cento power

i have a seicento 1.1 sx mpi 2002 i have a k&n induction kit with 3 cold air feeds and getting a sportex exhaust system would upgrading the throttle body to a 32mm or 34mm or 36mm help with performance at all and do you need to mod a 32mm to get it to fit

wheres the 3 cold air feeds ???? pics please ?

you have an mpi. so better bet is retro fit the 1.2 16v manifold, not much you can retro fit to an mpi apart from induction exhaust and porting.

a good service would do the car alot of good

it hasnt been serviced for like 15,000 miles so could do with one bought oil and filter and just bought iridium spark plugs would getting better HT leads help at all

Iridium plugs are a waste of money. You should of used the money on magnecore leads which perform the same as good quality standard ones but look the part.

Mpi seicento's have a 38mm throttle body as standard and is more than enough for a non reworked engine. Even the standard airbox works quite well.

is that inlet or exhaust mani?

 

[tony811976]

inlet as far as ive learned on here

you must be mistaken, a 16v manifold isn't going to a fit an 8v head.
