6A12 Mivec 2ltr V6 Performance

[VR4WGN]

what is the best way to get gains in performance on the V6 Mivec engine?
i know the basics ofcourse(NO POD FILTER) but mivec controllers or is there better ways to get gains noticeable?
i want to make alist of what to get for it,i would like to have it haul arse....

SAFC???or more than that?

MAP ECU is a standalone ECU Q, SAFC is merely a controller which intercepts signals from the MAF and alters them before sending them to the ECU.

[Nutter_John]

Ryan , Mapecu is a piggy back ecu made by a company in NZ , Ben H has had some good results with it on FTO Mivec's

maybe ftooc would be a better place to look

[Ryan]

I stand corrected on the MAP ECU. I believe my description of what the SAFC does is accurate though?

MAP ECU (or piggyback of choice).

Decent exhaust and intake. (including exhaust manifold).

Possible Cam re-grind / replace / timing.

Larger throttle body.

Then you're into headwork, porting etc.

After that, you will be looking to go for wilder cams and higher RPMS, which means precision balancing the internals, which means you might as well replace them for titanium components. By the time you've spend this much, you might as well have dropped in a different engine with forced induction. NA tune is much harder than Forced.

Indeed, either http://www.ftooc.org/ or http://www.mivec.co.nz/

Searching around first is the best idea, otherwise you'll have Nutter John joining up to tell you to search.

Because they are a highly tuned N/A engine any gains you get will be minor, maybe 5kw for an exhaust, another 10-15kw for an ECU and that will be about it really.

ok il ldo Mani and Exh, Intake(ram air??)
and piggy back ecu
and see how that goes.then do Cams

[VR4WGN]

what about this baby??

That ecu will be fine.

[AlanDITD]

You gotta realise though your never going to make much extra from them with those mods and mapping i would guess at about 25hp tops. Possibly abit etter ddriveability but thats about it.

[Turbo_Steve]

Actually, most of what you do to it is likely to compromise driveability, just like on the Hondas.

[AlanDITD]

well i guess that depends on how you set it up. With mine it was fine untill i put a harsh clutch in. The engine reved so really freely and idled fine it was just awesome to drive imo.

You guys havent mentioned chucking in a lightened fly wheel either i would def look at this if theres one available

[Dom B]

A full throttle body set up well resonant tuned will open up up to 20-30bhp more but it will cost mega bucks. As the guys said the mivec is pretty highly tuned as is so there is not as much to gain as say another engine could.

[VR4WGN]

thanx heaps for the info boys i really really apreciate it, fortunatly i am able to make a new throttle body easy as so that is a big possibility,would you reccomend not getting an ecu then and just doing all the add ons,EXH,MANI,THROTTLE?? and wht do you think of ram air in NA?

[Nutter_John]

what are you trying to do ?
why are youy trying to do it ?

answers to the abovewill help answer more questions

[VR4WGN]

i like knowing im 1 better than the other Mivec engines out there,you dont just put a mivec in a legnum and thats that,you play with it to make it sound good,look good and feel good right? hence why i want to know what the best options are,im not drag racing or boyracing but merly want it running beautifull,and have the extra performance if i want it.

like maby introducing the mivec earlier and having a good sounding exhaust is a few of the majors to me..

[Nutter_John]

Dude maybe you should to stick to what your good at and not try and run before you can walk .

You are playing in an area that you seem to have seem to have little knowledge , this knowledge can not be gained by asking questions on a internet forum .
