Mileage not as important as power and fun, but I'd rather not go below the 30s. I told them that ideally I'd like a lot more power, no smoke, and great mileage, and keep it conservative enough that I don't need to spring for a beefier clutch. I just got a Kerma tune, where they asked what I had for hardware, and what I wanted to do. It might be a good idea to talk with a guru and a tuner early. Now I would like to know what you TDIclub guys think of this: and an 02A five-speed transmission from a '98 TDI (the '98s had taller gearing that will help with our mileage goals" So I am ready to start this now, did some of the homework tonight and found out that the Rabbit sipster used an ALH engine but an AHU transmission apparently ". Now that I have introduced my ideas, and project I can add to this now that I have just recently bought a 1994 Golf (2.0 ABA) & a 1998 TDI Jetta. I have since changed this plan to a Mk3 mainly from learning from the ecomodder forums how little role the weight plays and how much the aerodynamics does! I figure I can lower the weight on a Mk3 much easier than making a Mk1 & Mk2 more aerodynamicīut more importantly I learned that Cd is only half of the story (if even half ) cause I found this info: So I first was considering to do a Mk2 and in fact started this thread on this other forum:
#Mk3 2.0 o2j swap driver
I was pretty sure I didn't want to start with a Mk1 (Rabbit) as they did, just because I want this to be a daily driver etc. Timing covers from the ABA 2.0L need to be used as the 1.Ever since I ran across the TopGear's Rabbit Sipster project I have wanted to do something similar. The timing belt from the ABA 2.0L is used because the block is taller ( 109 052) It is recommend to replace the timing belt tensioner as well ( 109 055).ĩ. Techtonics offers piston machining service to lower the compression for $100, this includes chemical cleaning of the pistons as well.Ĩ. 9.2:1 Compression is the most Techtonics would recommend on pump gasoline with out a knock sensor ignition. If your car wasn’t originally equipped with a knock sensor you can retrofit one from a ‘85-’87 GTI or GLI that uses CIS injection. The ABA engine has 10:1 compression ratio and a knock sensor ignition system should be used. ( 103 103S) OE replacement bolt set or ARP head head stud kit ( 103 102U) can be used.ħ. OE head bolts are a "stretch type" and should always be replaced. The head gasket alignment dowel pins will also need need to be changed to 6mm dowels (103 139). Do not use the 2.0L ABA head gasket as the oil drain holes are not correct. The head gasket you need to use when installing a 1.8L head on the ABA block is from the 2.0L 16V and Audi 80 2.0L, ( 198 137) composite or ( 198 137M) multi layer steel. The CNC machined plate is drilled & tapped for mounting the CIS warm up regulator in the factory location (used on the early Mk1 & Mk2 cars).Ħ. This kit includes freeze plugs for the 40mm hole for the breather and one for crankshaft position sensor hole which is not used. You will need a Techtonics breather block off plate kit ( 103 135) to solve this problem. Mk1 and Mk2 cars are set up for a breather outlet in the valve cover. The ABA engine comes with a breather tower on the front of the block. If you are installing the engine in an Mk1 chassis (‘75-‘84 Rabbit, ‘75-‘88 Scirocco, ‘80-‘84 Jetta, ‘80-‘93 Cabriolet, and ‘80-‘83 Rabbit Pickup) you will need the Mk2 or Mk3 dual outlet manifold in conjunction with a Techtonics conversion downpipe. You need the Mk3 downpipe or a TT downpipe ( 251 117S) in order to accommodate the taller block.Ĥ. If you are installing the engine in an Mk2 chassis (‘85-‘92 Golf or Jetta) get the ABA exhaust manifold and downpipe. (The 2.0L has a larger distributor hole and larger drive gear than the 1.8L)ģ. This will allow you to adapt your original ignition distributor to the ABA block.
You will need the Mk3 ABA 2.0L distributor drive gear as well as a Techtonics distributor adapter bushing ( 103 140). If you are installing the engine in a Mk1 or Mk2 Chassis you will find it easier to use the ABA short block and using your existing fuel injection rather than using the complete ABA engine, this makes it much easier because there is no wiring issues to deal with.Ģ.
