Hi yall,

Came across this 3.5l engine in the ebay thread and was wondering if I could put a 3.5l engine in a TF.

http://cgi.ebay.com.sg/ws/eBayISAPI.dll?ViewItem&item=160356389291&ssPageName=ADME:B:WNARL:SG:1123

Do they have the same mounting points? Would you need the ecu from the engine and the wiring loom? Would you need the driveshafts from the 3.5l as well.....

Not sure if anything else would be needed if I wanted to do a swap.....

PM Phonic. He did this to his TF and got a good result.

thanks.... :)

running a 3.5 in my manual TF sure the 3.0 used to rev like the clapper but cant beat the torque and wider torque band of the 3.5 as well as the extra kw

i have pacemakers extractors so the exhaust wasnt a problem if you have stock headers you will need the ones from the 3.5 due to the taller engine, re-use your uper intake and throttle body, the drivers side drive shaft mid mount is slightly different by 2mm you will need a spacer or washers for one of the bolts. do a search its covered more by madmagna when we done mine

As above, you will need to do the following assuming you are running auto

You will need to use the following off your 3.0
Aircon bracket
Upper manifold
Engine harness (one on the actual engine that plugs into the injectors)

Ensure that the 3.5 has it's original alt upper bracket as these are different

All of the rest you can use of either engine

Being auto, if you can get an intermediate drive shaft (solid rh one that goes from trans to drive shaft) from a TH 3.5 or KE - H Verada, this will go into your trans no issues and will solve the issue with the intermediate shaft bracket being different

You can use the 3.0 ECU no worries

way to expensive!
PM life, he knew a place that sold 3.5L engines for like $300 with warrenty.
i stuck a 3.5L manual into my 3.0L auto, like chalk and cheese

Riverside Spares in Moorebank I believe. SIK_WAGON99 has the info for it. He bought his from there. Looking at this one it would be much better though. Comes with a lot more.

hi guys,

thanks for the replies. I would love to change to a 5 speed auto as opposed to the 4 speed i now have. and considering this engine has only 69k on the clock, comes with a 5 speed tranny, wiring loom, ecu and cv drives, I am pretty tempted. However I know getting someone to fit it here in wa is going to cost an arm and a leg. It is food for thought though.

Its a day job mate, Old engine out new engine in, with the manual conversion add another 2 days onto it, so 3 days. It's still not *that* expensive, got a mate who can lend a hand?

got a few but not sure if they are any help when it comes to changing an engine. :) oh well, it was thought.

On a different note, would a 5 speed auto trans fit into a TF engine??

there are write ups that members have done here, i have written up one myself. just do some R&R on this site, and if your handy with a spanner, then you should be right

With a manual conversion add about 4 or so hours at most

With the engine out there is bugger all work to be done, the only hole to drill is the one for the master cyl, the fluid line goes under the insulation (not just thrown along the fire wall like some butchers do), the shift cables get changed over and a few quick wiring mods

If you want the 5spd tippy, you will need the engine harness AS WELL as the entire engine loom as they are different on the TJII to all the preceeding models of Magna. The differnece is in where the engine loom connects under the fuse box, it is not a big differnece but if you do not know what you are looking at could be an issue

You will also need to change the main dash harness as you will need to add the wiring that takes the BEM, you will need to either get a matching key set, BEM and ECU OR get Steve Knight to de immob the ECU you are getting

You will need to change also your cluster as you will need the indicators, the shifter will also need to be changed

good evening gents,

thank you for the comments. a lot of thought went into them.

The reason i started this thread was primarily because i would love to have a 5 speed auto instead of my current 4 speed auto as I do alot of highway driving and feel that it would be better. I saw the ebay ad that also came with an engine. While considering doing the entire swap, I was wondering if I could swap a 5 speed auto into my 3l 4 speed auto engine as this would be a cheaper option.

I would love to go manual but with a crook left knee, that would be a bit hard. :)
