I read somewhere that Pro5's in Australia or somewhere have a V6 option. Is this true? If anyone knows, is this the 2.5 from the MX-3 and MX-6? KL-ZE I think. If so, would it be a direct bolt-in? I would rather pay 3 grand for a six cylinder than a turbo,(horsepower for the V6 is 200 I think, pretty much the same gain as a turbo), then save more money and turbo the 6(although I hear the 2.5 cant hold alot of boost). Any help is appreciated.

 

what i want to know if the v6 off of the mazda 6 will fit in are pro's that would be cool...even there new 2.3 litter would be nice

 

Never heard this.

all the engines for the 323/protege worldwide are 4 cyl.

Not even the JDM market gets a v6

 

Well, they USED to come with a V-6, but not anymore. Several variants of the 95-98 BH-chassis Astina/Lantis/323F (foreign hatchback variants of the Pro) were sold in Europe, Asia and Australia with the same 130 hp, 1.8L KL08 V-6 that came in the MX-3 GS, or with a 140 hp, 2.0L version of the KL-series V-6 that was never used in any Mazda sold in North America. However, all of the V-6's got the axe when the current bodystyle came out. All versions of the BJ-chassis Protege have inline fours.

I doubt that a V-6 will bolt in to the BJ-chassis Protege due to changes made during the 1999 redesign. Actually, V-6's will not fit in a BH-chassis Pro either because of inadequate firewall clearance (the MX-3 used a different firewall). If you want power for your P5, you're better off looking at turbos than V-6's.

 

Oh well, turbo it is then...not that thats a bad thing Actually, I think I am gonna keep it NA. Just get the J-Spec cams and a CAI, headers, and a good cat-back. If I do go the NA route, is there anything else I can do for power; that wont cost an arm and a leg.

 

get higher compression pistons, they should be good for about 20hp, but it wont be a cheap mod. people on the board have done it and as far as i know it would cost a lil over 1000 to get it done. Also the ecu in our cars kills power and replacing it with Haltech E6K or Greddy Emanage or some other fuel management will also yeild some pretty big hp gains. hope that helps.

 

you would not get full hp gains from the high compression pistons with out some kind of ECU upgrade. I don't think the ECU would fully recognize the increase in compression You could install the pistons yourself to save money. If you don't know how, save the money for a turbo. It would be much more cost affective
