after having my 9 for a while, and my recent mivec cam snap, im scared to continue to run any type of mivec cam in my car, especially with my new stroker motor.

the 8s have been around alot longer, and its easier to find much larger cams for an 8 than a 9.

anyways, im having the master tech at the local mitsu dealer look thru his wiring diagrams to see if i need to swap harnasses, ecu etc etc.

he told me he thinks that you can just ignore the mivec in the wiring harness, however i may need an 8 ecu. wouldnt i be able to just tune my mivec to 0.0 across the map but wouldnt remove any of the other 9 features? therefore removing mivec completly?

thoughts?

 

what cam did u have, my friends S2 GSC snapped and broke the motor hardcore

i been running cosworths for a while, been good for at least 35k so far

 

i ran kelfords,

apparently kelford, gsc, and cosworth have been making bad cams for 9s, and theres not much of a choice on any other cams without sacrificing alot of performance.

id like to convert to 8 to run JUNs or something similar

 

JUN and TOMEI cams are killer for evo8's

 

yeah thats why i wanna convert to 8
if its harder than i am thinking, i may run FP5R

 

I was looking into the same thing. Does the 8 cam fit the 9 head? I dont see why the Mivec couldnt be diabled.

 

Jun makes cams for the 9.

 

You need to stop listening to your master tech.

You need the 8 harness, 8 ECU with disabled immobiliser, obviously the 8 head with cams and cam gears. The water pipe/thermostat housing is also different, the feed line length is different. It isnt exactly hard but its not easy either.

As far as your comment about bad cams, remember that is an unresolved issue for the exact point of failure. Saying that they make bad cams, when it could be one small batch that they bought from the billet manufacturer, or other reasons is pretty bold.

 

straight up, if you have an evo9 and you want to convert to an evo8 in todays time, your a dumbass.

Buy a good set of cams and reap the benefits of the mivec and additional flow, otherwise just sell the car and buy yourself an 8.

 

the tech said he was going to look into the wiring diagrams to see what it would take, and i dont care if it was a small batch.. im not going to take a risk and get one of the "bad batch" cams again and blowing my stroker.. so as far as I am concerned. no more kelford, cosworth, or GSC cams for me...

that dosnt sound bad but disabaling the immobilizer? no bueno.. ill stick with the 9.

thank you for the info john

 

and why does that make me a dumbass? considering that both ams and buschur use 8s on their drag cars, yet no one calls them dumbasses for not taking advantage of the mivec.

i have yet to see a 9 cam have as aggressive lift as any 8 cam.

not to mention, the more **** the car has, the more **** thats going to brake.

 

MIVEC = GOOD mmmmkkkaaaaay?!!?!?

There are a billion other guys out there running cams on their IX's that didn't snap. You got unlucky, get some new cams and get over it!

 

^word!

 

get the FP cams they give you performance just have to work with the idle. this is a pretty drastic change Kelford has already stated they are looking into the problem and will correct what ever it is.I think this was a result of a bad batch of cores.

buschur and AMS uses the 8's because they bought the cars right when they came out.

 

Yeah.... I didnt want to call him out on that.... he has talked to me about several issues and was completely wrong (the master tech)....

The 9 ecu even has a different plug. There are a lot of small differences, but unfortunately I think there are enough where the best option would be to have an 8 and 9 side by side.....
