hey i tried to search but couldnt find anythig.


my mum has a 1997 magna wagon 3.0 that blows smoke and the rear main is shot.
now would a 2000 th 3.5 engine and box go into it or not??

if so how hard is it and what is needed??

thanks heaps

yeah i can, its fairly easy, my mates and i did it over a weekend.
best if u can get your hands on a engine crane. everything should bolt, up
the only thing that didnt work for me was the plug that the injectors plug into, (cant remember for sure)
so i just swaped the whole unit over, took like 5 mins. i only noticed this after the engine was installed.
i cant think of any problems, oh and the exhuast manifolds, you will need too.

so would it be old engine gear box loomand ecu out then new 3.5 engine,box,ecu,loom in
is that all that needs to be changed over??

Just grab the 3.5 and the 3.5 engine pipe, use the top manifold and wiring off your 3.0 and should be all go.

Make sure when you start it up for the first time you leave it idle a while for the ECU to learn again as it will be pulling a little bit more air being a larger motor, the ECU should adapt ok.

after reading the aftermath ot the dyno day that low rider was apart of i think that is not the case, i believe his car was still running lean after a few months.

yeah was running too rich, but the car runs fine, apart from lacking low down power, like under 1500rpm.
so a tune is in order, other than that, runs perfect.

ok thanks, so use to old 3.0l loom and just the 3.5l engine and gear box but change the top manifold

thanks heaps for the help.

Lol here we go again, 10.0:1 is rich, not lean

There have been many done over the last few years and AFAIK they are all still going strong

Personally I prefer the 3.0 as it is a revier motor.

ah yes i have notcied this, kinda do miss it some times.
but like they say, no replacement for displacement
