hey

i want to put an EA T5 onto a au series 3 engine into my ea. I will eventually have all the original wiring out of the au into my ea. The au is a 4 speed auto with economy switch. My question is will i need to get an au series 3 manual computer and will the T5 fit on the au ser3. If i need a computer how much and where can i get it from.

thanks

ben

Pretty sure you will need a manual computer, it makes it a lot easier anyway. Just remember the EA T5's are pretty weak and the AU engine is over it's max torque rating.

are you running the BBM from the AU engine... My car is running the auto computer, but is a manual...

If you dont run the BBM manifold from the AU engine, you will be able to run the EA MPI computer...

It might be a stupid question, but you have got thermofans???

hey... so does that mean the t5 from an EA will break with heavy driving ??

yeah i have thermofans from AU. i really want to use the complete au setup because it has more power and better fuel than the EA MPI.

thanks guys

Yeah if you treat it hard it has a much greater chance of breaking, be nice to it and it should be fine.

You are going to need to by-pass Smartlock, if you want to use all of the AU wiring and computer etc...

I am going to be upgrading to an AU engine soon, and I am going to keep the existing manifold, as the flow rate i think is a little better up in the rev range then and BBM.

The EA 5 Speed is the weakest box eva... With a bit of thrashing it wont be looking too good.

You will get plenty of pep out of your car if you keep your original inlet manifold. Also, I think the ED inlet manifold flows a little more than EA-EB Manifolds...

I have 179 rwhp and i havent done many mods at all. Best thing is put a better cam in...

Yeah the fixed runner manifolds do flow slightly better up high but you loose a ton of power through the midrange. BBM take about a second off the 0-100 and 1/4 mile times so I would be using the BBM if possible.

change the diff gears and he will be laughing...

15.153 qtr time for me... and that was with a cactus EA 5 speed too...

I have to try again with my new box...
