i have a 30v 2.8 motor with 115K, withtranny and eveything, ecu, mounts and all that gud ****, with new timing belt and water pump done at 100K, it was given to me from a family member so i kno the history, i paid nothing for this motor, is it worth me removing my 205K 12v motor and tranny from my 96 A4 and putting in the 30v? and if so wat major problems will i come across? please reply

 

no

 

That's a keeper.

 

I think the blocks are the same, if so, it may be possible to just switch the harness and heads so removing the block and transmission wouldn't be necessary. However, is it worth it? Simple answer: No. the 30V is ratted for 20HP more than the 12V, which is marginal to say the least for the amount of work. Besides, there's acutaly *more* aftermarket bolt-on support out there for the 12V than the 30V.. the only worthwhile mod for the 30V is the supercharger.. which I believe they don't produce any longer.

 

Um... no. Not even slightly true.

I would say that since your 12v is starting to get up there in mileage, keep it in the car and put the 30v in storage. Then, when your 12v finally gives up in a few more years, swap in the 30v to keep the car rolling.

 

if you have enrtyhing and the time its doable, everything would be the reverse of removal, and yes i have seen a 12v turned 30v.

 

If you got it just sitting around definetely do the swap. You'll just be prolonging your cars life along with your piggy bank swelling. Are taking the task on yourself or getting it done ?

 

agreed. and even if you werent going todo any aftermark performance mods youll notice a big difference in the 30v even if it only has 20hp more than the 12vjust cus it can breathe so much better

 

Well worth it in my book.

The 12V is a bit of a nail, to say the least, and seeing as the 30V was free...

Do it.

 

im def. goin to have it done, its my project car so the guy who's gonna do it is goin to take his time
