Hi Guys I tried to look for Welly's engine rebuild info after his rods went. Cant seem to find it.... So I have a few questions. Im in South Africa, owner of a 02 8L S3 BAM Revo Stage2. My car blew oil through the turbo & zaust just 2 days before 112K Miles service, whiles doing freeway driving. I took the car in & mech he asumed it was turbo seals that blew. I asked him to remove turbo by removing the head & @ same time Id do the rods. He refused to do it, since in SA we dont really see rods going on 1.8t's (since the guys crash them be fore the motors pack up) So of he whent & removed the whole motor against my liking. Removed the turbo, xaust housing cracked, oil oosing out all ova. We had a TFSI K04 that was in his workshop & we discussed hybrid/Big turbo options long before the turbo failed & I opted for hybrid for factory look & feel. We then used the kompressor + turbine of the FSI K04 which we thought would match. Machined the housings sothat the new 'propellers' would fit. SDC12536a | Flickr - Photo Sharing! After refitting everything @ startup, cylinder2 had missfire..... Found that cylinder 2 could not pass compression check. Mech than removed the head & found a hole burned in piston & damaged to block. 06022012131 | Flickr - Photo Sharing! Thus the need of new block burn in block to deep for repair... SO best value for price motor we could find is a AGU motor. Heres a few questions....... 1) AGU block with BAM head vs BAM engine. Compression is higher of AGU. Will different mapping be needed for Standard K04, AGU block, Bam head with revo 2 currently on my S? 2) 1 of my injectors failed. If I decide to buy a set of 440cc bosch green giants & fit them on my S with Revo2 can the fueling be calibrated say in the Revo2 soft or limmiwinks. 3) I do not have a custom ODB2 audi soft dealer for hybrid turbo setup in my area, closest is a 9hour drive away! What do you guys think of Unitronics Piggyback ecu setup, wich is the only option in my area except Revo dealer.
