hi i need help. i have a mk2 gti 1.8 8v pb and i have a abf engine i want to install, i have the whole car but its got a stainless steal exhaust manifold and from what i read it might not fit because of clearance issues? i cant seem to find a standard one anywhere, can anyone point me in the right direction or tell me if there is one i can use off a different car? thanks
the manifold from a mk2 or mk3 16v, plus corrado or passat 16v will fit, if you are going with ABF managment then you can use a mk3 2.0 8v/16v downpipe on it plus decat pipe, then fit a mk2 16v exhaust. the corrado 2.0 16v or g60 downpipe will also work with a decat the same way. if going with kjet or using aftermarket management without a lambda then you can use a std mk2 16v downpipe. alternatively you could get a boss welded to a mk2 downpipe at a local exhaust place, the abf managment will drive ok without the lambda hooked up, so you can get it in and sorted then drive to a an exhaust specialist to have the boss sorted
yeah the 1.8 and 2.0 corrado, passat, mk2 and mk3 16v manifolds are basically the same just some will have a sniffer pipe and others wont. seat 1.8-2.0 16v also have the same manifold but harder to get
I never advise that complicated and fairly costly step, nor will a garages well versed in engine swaps. If you already run a GTI MK2, to simplify the swap you can use the original GTI 6 bolt downpipe and weld a lambda bung into the exhaust stream at the collector of the manifold to allow fuel trimming to lambda 1 part load. ABF engines with Digifant 3.0 or 3.2 controllers do not 'like' running without the lambda input when warm and while they will start and run without, part load fuel consumption goes up considerably and your throttle response reduces. If the MK3, 8v/16v downpipe components would just simply fit to the original cold end without buying any more components, then on the basis of taking time to convert and document the "How to ABF your MK2 Golf", I would have included this step for the average DIY installer. This is why I have recommend to simply contact a friendly exhaust center and weld in a boss perpendicular with the parallel part of the piping, merging in at an angle to avoid condensation on the sensor. Here in London, the Style Dynamics guys, are pretty versed with this operation and it takes a lot of hassle out of the conversion, once you can get the car to them. They will check the rest of the system as well. I do know what it is like to carry out these conversions on your back and will give tips that helps the end user save money and time as well. The option simply adding an exhaust bung to the MK2 system will be at a fraction of the cost to source a MK3 downpipe, when one is not required and also sourcing some aftermarket made de cat pipe to link the rest of the cold end.
thanks i have been reading your guide its really helpful. could you tell me what i need off my engine for the abf other than gearbox, like any water flanges i need to transfer? also the mk3 i have has a purge valve do i just remove it and block the pipe? i plan on keeping the abf ancillaries power steering, water pump etc if that's possible?
You need the complete engine which will bolt to your 8v gearbox, once you swap the 8v clutch, pressure plate and flywheel. These then mate to the 8v downpipe. The evaporative components, such as the purge valve and canister is not required. and blanks are placed on the outlets. As in my own car, the stock plastic top hose flange works with a trimmed down 8v top hose. A small kink is left but I have been driving this engine set up like this for the last 50000 miles. If your car has power steering, then you can use the MK3 PAS pump on the doner engine, bit to keep all the MK2 PAS lines, the valve from the MK2 PAS pump will need to be swapped over. My signature has the links for "How to ABF your MK2 Golf" and the JENVEE thread. Have a look there and ask any questions. JENVEE, is a car that I actually drive daily and has many components that I can recommend for a user attempting to do the same. That car is driven in many situations, including EU trips and on track. It provides a practical and running example of what works and does not work on an ABF powered Golf MK2.
Hello, i am reading your posts dor a while and i have one question for you. Recently i made an engine swap into my mk1. I have 2.0 16v abf but i can't figure out why i have so much rich fuel/air mixture. Black smoke is comming out and the engine runs a little bit rough when hot. I've changed almost everything. Tps, o2 sensor, spark plugs, spark wires, distributor cap with an rotor arm, etc etc. colud the problem be at the coolant temperature sender beside the fsct that it gives good readings at OBD?
