I currently have an 01 Audi A4 1.8T with a K04 20psi and methanol injection that has right about 200,000 miles on it. I drive it every day and not all that nice to it. I have a gt28 for it but I also have everything I need to rebuild it, which is getting done soon.

[@UngluckInc]

@@4BillC 260k miles over 14 years making 500whp in a MK1, 1.8BT ftw. drop in rods(aged arp 625 fasteners), re-used pistons with fresh rings and a light hone. OEM bearings.the amount of track time I have on it is crazy, as well as daily duties and cross country. Def an incredible engine the 1.8t20v, but my '17R has been incredible for it's 75k miles so far.

[@4BillC]

@@UngluckInc that's what's up! That's basically my plan! H-beam rods, stock pistons new rings and bearing. Going to keep the stock valves but upgrade the springs (only bit I don't have yet) just so I can rev a bit more. I currently have the rev limited to 6800 just because I'm scared of valve float. I want to be comfortable at 7500.

[@itschefff]

The bad O2 sensor and cutting out you mention, is that common? I seem to be running through O2 sensors fairly regularly (three in the last two years) and no one has been able to figure out why the car will just give up mid-pull. We’ve replaced my wastegate actuator thinking that was the problem. The turbo itself doesn’t have a ton of miles (under 10,000) and the internal wastegate still seems good but when it’s deep in a pull it will just release all pressure like the wastegates opening. If it matters I have a fully built bottom end but the head was rebuilt with stock parts at the recommendation of the shop that did the rebuild. Prior to the rebuild it made 458whp on 91. Now it’s making 375whp on E85 and it’s stumping everyone.

How did you guys like the boss750? Considering picking up a used R early 23 as these prices start to drop. Thinking of doing a "low budget" R build with a stock/catted downpipe, stock motor, stage 3 clutch, boss750, MPI, and an LPFP. I once had an IMS710 R with a DQ500, but that was completely unregisterable and it broke axles constantly (and a lot of other shit). Looking to build something more tame, manual, and daily-able. 500ish whp and 420ish torque.

Hello CO Motorsports! My name is Timothy and I have a minty mint 2016 Jetta Sport 1.8T completely stock. I want to build my car up towards Stage 2/3.

I am 34 and I am currently fighting severe skin cancer and I would love your help/guidance. Please get back to me. Tim H.

[@COMotorsports]

Sorry to hear Tim, typical turbo upgrade for these is GTI or Golf R turbo. Whatever software you start with just ensure they offer a turbo file for those turbos so you're not purchasing different software down the road.
