I have been looking at upgrading my car in a few different ways; maybe a body kit / rims or engine upgrades. And that brings me to my question, has anyone made thier 1.8T into a twin turbo? (I have a 2002 A4 1.8T quattro w/ tiptronic.)

 

why? you can just upgrade the turbo itself and push the car up to 400ish HP with supporting mods

 

I was thinking twin would be cheaper, and it sounds cooler : )

But to be honest im open to anything.

 

To be honest, i have never heard of anyone ever twin turbo a 4 cylinder engine. You would probably lose all efficiency of the second turbo. You can only ram so much air at a time.
Like what 1move said, it would be better to do one big turbo...start at a K04, the maybe 2871r

 

Yes twin is cheaper and even has 4 cylinder engine, go for it

 

sorry, you lost me on this one. i dont know if your being sarcastic or not.

if you were being serious, your wrong. Cheaper definitly not. Look at the turbo alone..how is 2 of something going to be cheaper then 1 of them? and the second part about it "even has 4 cylinder" i jsut dont know what your trying to say.

 

Swapping it to a S4 engine yea--> ttp://www.audizine.com/forum/showthread.php?t=239013

 

get a biger twinscroll and stay single a sequencial turbo set up will give about the same preformace but for more money not worth all the work fabing and tuning

4 cylender engine is not too costly , i suggest u this.

 

i've done a few twin turbo setups, but in my opinion a single is far cheaper and just as useful. a twin setup on a 4 cylinder is just not worth the effort. if you want something different, then go for it. pm me if you want to see pics of my work.
