hey guys ive loved my magnas for a long time so much to the point were ive written 1 off and gone out and got another 1 lol.
its got 400,000km on it neva been rebuilt so im positive it needs 1 as its using oil and blows abit of smoke.
im thinking of rebuilding it into a high compression monster but im after some ideas on parts and what matches with what e.g i read that if i went stage 3 or 2 cams i would need dif valve springs..why is that? is the clearance?..
any way..i can do most the work my self saving a dirt load so basicly can u guys throw me in the right direction in the way of great upgrades to get a pretty quick magna..
im very familur with cai setup and muffler system after that im just going on what ive been reading but i wanna make it right the first time...basicly im after a revy engine i have the 3.0l so its revs are pretty snapy any way but could make it better lol cheers guys

HI mate welcome to the club FYI there is a search button in the top row bar this is always a good starting point for info check there first you may just find the answer you are looking for then if not ask away this question has been covered quite few times before.check this link out.http://www.aussiemagna.net/forums/showthread.php?t=71842. There is wealth of info here bound to find things of interest enjoy your stay .:hmm:

Basically the 3L isnt going to wow you without forced induction no matter how much you do to it (within reason). I would say a 3.5L could be had for not much more than a rebuild on your current.

Welcome Andrew. What you have to do is figure out how much you have to spend, and then spend it wisely to get performance that you can live with long term.

The valve springs have to match the cam. The mild Ralliart Magna cam was apparently OK with the stock springs but Mitsubishi was worried about their durability so nitrided the stock springs. The other issue is that the stock spring is close to coil bind so even a mild high lift cam requires a different valve spring with more space between the coils.

For a heavy road car generally for performance the bigger the engine the better. The 3.5 would be a good base to build on and if you have the $$$ then a 380 engine is much better. It already has better cams, bigger valves and bolts right in with a few simple changes.

Cheers,
Alan

I second the motion for the 3.5 conversion. I recently did it to my car, and my 3.0 was running fine, and it still blows it away. So with your old crusty 3 litre it will be in a different league.

I had trouble finding a cheap option in SA to start off with because most of the good motors for sale are interstate, so you shouldnt have any trouble finding a nice engine package for $500-700
