      Just an update on what has happened to my project.
      I had a crash with the car at the http://www.speedfestival.co.za/. I took a long time to recover from the damage to my S2.

      I bought a 3B to transplant all my mechanicals (easier than fixing the body), which I never got round to actually doing.

      My fiance bought me an ABY S2 show car for my Birthday this year which a motor museum curator organised http://www.fmm.co.za/.

      I now am not racing the S2s anymore but I love driving them daily

      So now we have a His and Hers in Red as well

          Hi guys

          I'm starting to gather all the parts necessary to mod the ABY.

          I will be using my original engine which has:
          strengthened bottom end
          RS2 Head Gasket
          ADU Cams
          Mildly flowed and ported head
          Wagner short intake
          RS2 EM however I will change to T3 Wagner if need be
          3" decat exhaust
          VEMS

          Now I have looked at the following turbo options and would like your views on them
          Volvo k24 7400
          GTX2876 ...is there a GTX2871
          PTE5558
          Or what do you recommend

              I forgot to mention that I have revised my power goal to under 400 maybe even 380HP to gain better street drivability.

              I am using the car purely for street now and not events so a smaller turbo than the gt3071 I had before will be more suitable.

              I am sure newer technology now must provide a quicker spooling turbo than the old RS2 turbo and offer better or similar power. Hope you guys can throw some light on what works on our cars.

                Since you are running vems and have the option to play around with settings and hardware I would suggest you buy a GTX3071 with 0.63AR for your goals. Also buy the ADU cam pulley as well if you don't have it in order to take the full effect of the adu cams.

                This setup with the rs2 manifold should give you a close to 3500rpm full boost on 3d gear and certainly 4xx power numbers.

                You could go the other way and get a GTX2871 but my personal view is that the wheel diameter should be at the largest possible to have the same effect rather than getting the smaller wheel and then having to change all the turbo if its not enough. GTX3071 can always produce more on the larger hotside if need be which is not a costly upgrade.

                My current setup with the HTA3076 on 0.63ar and mild head porting is around 470ish but comparing prices of buying a turbo from scratch, if I were to buy a turbo now to get to the same number and spool/lag I would get the 3071 instead.

                  I eventually got down to installing the VEMs as well as the custom shocks, Whiteline and RS2 FARB.
                  Boy did I miss throwing the S2 around round abouts. Now that I have it handling again like it should (well I still need to decide what I do about getting some neg camber), I got down to installing the VEMs with the help of a tuner her in Cape Town.

                  Idles bad, boost comes in too early but this is just the beginning. Pleases to say the MAF is removed(I'm not sure if there is a setting somewhere in VEMs to tell it there is no MAF). I'm decided to do all the setup using the stock S2 turbo. The next step is to install my forged engine and the 3071 with Siemens 630s and 044pump

                    Hi Guys
                    Just a check in after a long sabbatical
                    Hope everyone is keeping safe

                    The Red Baron lost ignition while driving over a year ago. We could not find the fault. Plugged the OEM ECU in and it says hall sender issue. Changed it 3 times to no avail.
                    So I put the Red Baron in storage and now decided to change the triggering to 60-2 and buy a more modern ECU.

                    Boy, have I discovered that the world has changed so much since the days Mihnea, Doug, Mark H and many many others gave good advice. The S2 forum has always been a great place where knowledge and experience is shared with people whose S2s are their hobby and passion.

                    However when it comes to the ECU, it’s a completely different world, the poor tuners are dead scared to give any advice or services, looks like they have bitten one too many times by unscrupulous people.

                    Anyway the world has moved on from simply buying a chip set for the Bosch ECU (life and choices was much simpler then).

                    I have a Motec in my EVO 9. Supplied by Simon Norris Designs which is a great plug and play ECU but this is not available for our old classic S2. I read a thread hear the other day about the ECU Master. Looks like it’s something I could consider, I reached out to Dimitri who is a dealer after reading a thread about this ECU, he has directed me to a reseller locally unfortunately they do not stock the plug in harness for their Black Edition, just their classic which will probably be suitable for my needs

                    Are there any other recommendations on a more modern plug and play ECU where I will be able to change the triggering to 60-2. This is to just make things simpler and easier to maintain in the future like I did by illuminating the MAF with the previous ECU.

                      MaxxECU seems to be a popular choice and there is a harness adapter for the I5.

                              Thnx Guys

                              I have ordered the ECUMaster today. I will build my own adaptor, will put my engineering qualification to the test. Found out there is good local support for the product and its gaining some market share in SA.

                              I'm going to build the 60-2 gear on the damper. Already invited to a premier classic hillclimb so looking forward to getting the Red Baron on track again.
