Has anyone tried to use a Mazda 3 MPS motor in one of our bad boys? I'm thinking of trying it though if someone knows more than me and can offer any advice that'd be sweet.

My main concerns are the AC piping behind the exhaust where the turbo would sit and the drive shafts -> hubs (not in order of priority! haha)

I figure standard block should need little to no modifications to the engine mounts/mount points.

Side note: I'd say one would lose dash entirely or some features with Mazda computer running it but lets face it, PI or MoTeC would be the way to go

Oh, the reason I'm suggesting this is 100% more torques, 75% more kW's and it is 25% lighter than a Mazda 3... The kicker is it is a "factory" engine so it should be reliable!

Cheers, Steve

there's a bloke doing a project thread on his fiesta st with that engine!

if i remember correctly he's having a bit of difficulty fitting it???

 

Fezzy on there is doing one but most of it is now ST parts and the mazda ECU has had to be ditched.

 

Thanks guys, reading fez's stuff now... Pic's of the engine are interesting. My boss and I were wondering if the exhaust would fit

 

only just realised there was a fez st forum on here

as Si says ive had nothing but problems even converting it back to standard injection
is a pain

 

dont ruin the engine

 

the standard MPS engine has steel rods / crank and forged pistons as standard.

great engine to use IMO

 

there was a guy on fiestaturbo.com who done the same type of conversion to a mk3 he used the ford 2.3 duratec which is the same lump basically, he changed the pistons though and had to change a few pulleys and what not to make it fit. his user name is jimmyesh this is his build thread http://www.fiestaturbo.com/forums/mo...hilit=jimmyesh
have a read i'm sure you will find some useful info even though its not a st you can get the idea of what is involved hope this helps a bit, good luck with the project if you decide to go ahead with it. Obviously there will be complications but thats what modifying is all about you live and learn
