Hi i am about to buy a 1991 diesel Jetta. I have never owned any diesel vehicles before so im in the dark about this. How difficult is it to add a turbo to my normal Jetta diesel engine? I do konw lots about gas turbo engines and am wondering if i will ened a new ECU ( If the engine has ECU i dont know) THanks.

no ecu,the engine is mechanical.You can add a turbo ,but to get more fuel under boost you will need a different pump,if you want it to run proper.you can run without "boost enrichment",but you will smoke when not under boost.tap the oil pan for drain and the oil filter housing for feed,schaabam!

Haha sound easy. what boost can these cars run? is it the same engine as a turbo diesel minus the turbo? What would i need to get it to run just like a stock turbo diesel 1991 jetta? Thanks alot!

The turbo diesel engine has oil squirters under the pistons which stand for oil cooled pistons... the piston material is different and the IP.

You can definitely add turbo to a normal diesel engine if you are not going crazyy with the boost!

You need a turbo IP and a Garett T3 or a KKK k-24... these are the two turbos that came as stock... you can also add an IC which was stock in the GTD version... but that was under the hood, go for the front mounted IC; its always better!

If you want reliability id stay in the stock 8-10lbs.The t3 and k24 is capable of 25lbs.Start thinking of some other kinds of cooling.Oil as well as charge.

well that sounds easy enough, but not im thinking my engine has 330K Kms on it is there a newer turbo diesel engine that will fit into the engine bay? What would be my best choice for my 50 ish mpg and more power? Thanks for all the help so far!

THERE HARD TO FIND AND ALITTLE PRICY BUT ID VOTE FOR THE 1.9aaz DIESEL TURBO ENGINE.

IF NOT FIND A 1.6TD ENGINE....CODE mf OR SO ON
GET A ROBERT BENTLEY TOO...IT'S THE MANUAL OF CHOICE FOR VOLKS AROUND HERE!

Ok thanks, is there a section im missing on the forum for engine swaps? Also what year of car does the 1.6 TD come out of and is it a direct fit and what kind of electronics does that engine use Thanks.

1.6td in us is found up till 92 i believe.canada 95 as well as the 1.9ltd if your up north.these(1.9)will swap in though.as far as elect. theres a starter,glowplugs,temp sensors ans switches,radiator fan,one wire to run the fuel shutoff on the pump.pretty easy when your used to obd2.

perfect thats very simple so no making new mounts? How about the cv axles would i need different ones or would the originals work? Also how big of a difference in power is the TD 1.6 compared to just the diesel. Thanks!
