What to buy for MIVEC?

spetz · Post by **spetz** » Sat Dec 25, 2004 9:56 pm

I assume when hotting up the MIVEC you do it in the same way as any other engine.
But what brands? What increase do they have?

RPW seems to be good for this kind of stuff, but they don't seem to have any proof/dyno runs???
Basically it seems that if boring 5mm from the TB on a 4G93 gives some power, then the same should be done to the 6A12 and it "should" increase power.

What is the recommended path I take for doing the engine up?
At this stage it is a stock engine with high flow cat and 2.5" mandrel exhaust.
Next mod is an Apexi power intake filter on custom piping to behind the front bar. What do people think of this? Any risks from dirt/water? I will clean the filter after say 4000 km everytime with an oil change.

After that, I was thinking RPW Race Extractors??
Then overbore throttle body
-Fuel Pressure Regulator
-Greddy Emanage
-Finally maybe some cams, but which ones??

Any help would be greatly appreciated!

I just wish that I had the money to afford all that!

Does the cat make much of a difference? Did you change it or was it already on there? That is probably the next thing on my shopping list (after some new discs), but it has not really been discussed on this forum very much.

The car is actually a lancer with the MIVEC V6 not an FTO, and the exhaust including cat (which he said was better than the stock one) was fitted by the person doing the conversion.
It was a drive in drive out deal with all that.

Anyway it's not like I am going to be ordering those things tomorrow, probably over the year of 2005 I hope to have them all.

Anyway, back to topic...

Is Boxing Day & Iâ€™m lazy with few hrs of sleep, therefore my asking would sounds weird hehehe

RPW don't make race extractor, it was a one off.

Don't expect a world of different, as I already done most of the stuff u had mention. Heres the list below

RPW extractor
Adjustable FPR
9.5mm spark plugs lead with iridium spark plugs
Ported & polished head
Pod filter with heat shield & CAI
Cat back 2.5" exhaust

I had the 16bit Unichip before, but no one can tune it properly for my FTO, thatâ€™s including every dealer in Vic that was recommended by APS (makers of Unichip) I might get a 32bit version later. But for now Iâ€™ve got a SAFC.

They sure would give you a great dyno result, but its not that much different on the street, itâ€™s still an FWD N/A after all. I am happy with it as it does catch lots of cars by surprise, as people always under estimate FTO.

I'm waiting for Steve with his throttle body project, & hopefully it will came through soon, if not RPW can do them for $220 on exchange basics, & according to RPW you have to machine the throttle intake to match as well.

The cam from RPW would end up costing (including freight & labour) around $2500-$3000. Steve did mention his also working on that too, hopefully he can reduce the cost of the cam. I never heard anyone had done one with FTO or MIVEC, but on another type/brand of cars it produce good power but you end up with a rough idle as usual.

Ok enough said, i'm going back to bed now

I hope your not forgetting suspension and brake upgrades

hehehhehe me or spetz?

No there's enough spent on both suspension and brakes.

So, after all those mods how much of a difference did it make?? Was it clearly noticable? How far ahead of a stock FTO would you be?

Should I just try supercharging it instead?

With Steve's cams, I don't like the idea that they re-ground stock ones. RPW ones are billet and brand new

Power is noticeable, I never bother drag a stock FTO, don't see the point when I know Iâ€™m going to beat them anyway, so I don't know how far ahead i am, maybe not much off the line, but i know there are fair bit of different at med to top end.

I don't think is a good idea to supercharge a 6A12 MIVEC, apparently RPW use to have a supercharge kit, but it keep blowing out engines, so they went back to turbo.

I wonder if anyone had the RPW cam, maybe you can put a post at some of the UK FTO site, as RPW export lots of their stuff to UK.

Would you say the noticable difference in power was worth the few thousand in mods?

What's the UK FTO websites? The problem with RPW is I talked to David about the cams and he said he has no dyno results or no feedback at all from people with those cams. Basically the way I see it is that he applied some theory into building those cams but there is no proven results. This makes me a bit uncomfortable as I remember a while back there was a problem with some 4G15 SOHC cam where he sold that and an E-manage or something to a customer and the package just couldn't work.
And the MIVEC cams are $2500 or so (plus valve gear and fitting) which is a lot of money to waste for something that has no proven results
