Hi Guys
I have a 1997 3.0lt TE Magna Advance 5 speed manual that i crashed and and i want to do a conversion of the 5 speed manual into my 1999 3.5lt TF magna wagon,

My questions are will the box fit the 3.5lt enigne?

Do i need to change the ECU and do i need to find a 3.5 manual ecu

and what other complication will i runn in to?

yes it will bolt straight on, your gear ratios will differ to the 3.5ltr manual setup, no ecu change is required

That good news just confirming that i dont need to change the ecu even thought the TF is a auto

MadMagna is required lol

MadMagna might point out that the 1999 Wagon will most likely be a TH ;)

Also, I have a feeling I've read some people like to put a 3.0 box into a 3.5 engine because it gives more torque lower down? But I could be VERY VERY wrong.

Yo, Mal - where you at?

No TF's were made in 1999. The last was made in December 1998. Unless its a late TF that was first registered in 1999.

Ok
For starters, if you have a 3.5 TF either it is a TH like posted above and first regd in 1999 as the TF was not made then OR you have a TF with a 3.0. TF did not come with a 3.5 ever. May also be a TF with an engine conversion I guess

Now, to put what you have into your current car, just look at my members rides and that will be a good start, in short is pretty much a bolt out bolt in, if your clutch was not reasonably new I would look at replacement while out which I can supply you with but other than that, aside from some little neat wiring tricks you can if you want use the auto ecu

BUT if you have a te there, why not use the engine loom and ecu from it while you are there provided is not a TH OR your TF/H does not have features that your TE does not have etc

You are right it is a TH Bulid 07/99 with a 3.5lt and auto

a thread out of date but mine is the opposite question i'm searching for answers: i have a ' 97 wagon 3lite? auto equipped with airbag safety & abs brakes plus i have a '99 sedan 3.5 manual with zilch such things. i wonna convert wagon to manual keeping airbags/abs but here in coffs harbour been asking and replies says i can keep such & such stuff & not that wont work cant do it. any 1 with brains got more experience knowing who can lay it straight.

Well for simplicity you could just fit up the 3.5L gearbox to the 3L engine. You'll probably need to modify the sandwhich plate a bit - but it's nothing you can do with an angle grinder.

However the 3.5L manual gearbox has longer first gear ratio's and coupled with the revy 3L engine - it could be bit slow off the line.

Ideally you'd want the 3.5L engine as well. That could get a little more tricky though. You'll have to check with Mal (Madmagna) but I don't think you can use the 3L ecu with the 3.5L engine and still retain all the abs, airbag etc features. I know Presti is using a 3L ecu with his 3.5L engine conversion but he doesn't have cruise control working (yet).

Finding a 3.5L manual ecu to work with abs + airbag's, could be quite difficult. It'd be probably easier to find a car with a 3.5L auto ecu + bem + dash loom & engine loom and then crossing a few wires on the inhibitor switch to make the car think its in neutral. It'd be a bit of work but the 3.5L engine has more power and a better torque curve than the 3L which lacks a lot of power down low.

ABS and SRS have nothing at all to do with the ECU, they are completely separate systems

So aussiecraig, please when you post use some sentances and grammer, will make reading your post so much easier

What I can tell from your post is you have

97 Wagon with SRS and ABS 3.0 auto
99 Wagon with no SRS and no ABS

WHile you can put the SRS and ABS into a wagon, you will not be able to use the TF gear in the TH as they run totally different systems, if you were to use the TF system you would need to use all electrics etc etc, also either way you need to change front hubs, rear hubs, brake lines just for starters as well as removal of dash to weld on pass side air bag brackets. The list goes on, I have done this before to my car as well as others but is a big job.

You can run the 3.5 with the 3.0 ECU no worries. Perhaps your best option is just to put the 3.5 into the TF wagon and leave it at that

okies and i'm not actualy a genius people do make mistakes.

That's fine, don't need to be a genious, just try and split posts up a little please lol

Is there any particular reason you want to keep the th over the te/f

Is there any particular reason you want to keep the th over the te/f:

its the other way round:

1999 th sedan with manual gearbox no safety features.


1997 tf 3litre/ auto wagon with safety features equipped airbags and abs.

i want to swap the 3litre auto in wagon to 3.5 manual from sedan.

So as you said in your PM's to me - you want to transfer BOTH the manual gearbox and the engine from the TH into the TF wagon. Is this correct?
