  1. Jacques, I think sport seats from S4s and GT3 are the same, and sport300 one is different from them, not only the extra seat belt seat. The seat shells can be still ordered from SWLC or other. regards, pan
  2. Hello all, I would like to have my seat shells trimmed as same as the S4S sport seat. Mr. Mike already helped me a lot to send some photos to me, but the trimming shop advises me to send some photos of the rear of the seats, especially the headrest area and under the headrest area to see how and where the drawstring works, and the photos of the underside of the leading edge of the cushion on the seat are needed too. If you have the S4S sport seats in your car, would you do me a favor and send me some photos? I really appreciate it. thank you. Regards, Pan
  3. Dear All, I am very interested in the carbon parts such as doors, tailgate and bonnet and engine cover. Does anyone know who still can make them? Thank you so much.
  4. I gave up the idea of upgrade T3/T4 to ball bearing, I would like to buy G25-660 instead of EFR6258 or 6758. I already rebuilt my s4s turbocharger and keep it as an original part, the shop charged me around 600EUR. They did a perfect job expect the price and no name plate on the compressor housing.
  5. Mark, both of the inlet and outlet of turbine are V band but with different size, Is it possible to send Alunox the turbocharger or turbine side for alignment?
  6. Around 400whp. I want a really fast spool up time and response. it seems that g25 series is a good choice for this and its efficiecy is much better than EFR7670 , it has smaller compressor and turbine wheel and I can choose a 0.72 turbine housing. So I think it can compensate its weight. But G25 is lack of the choice for turbine flange and no twin scroll choice for 0.72 A/R.
  7. Hello mark, Can I order a V band flange?I plan to run Garrett G25-660. My MKII seems too close to chassis tube, I would like to buy a MKIII are there two version of MKIII? It seems that they have big difference at downpipes from cylinder 2 & 3, one is similar to MKII, another one is a different design.
  8. Hello All, I would like to upgrade the T3/T4 turbo of Sport300 to an ball bearing one( Does everyone know the specs of the turbo? I just know its turbine AR is 0.48, I have no idea what the compressor wheel trim and compressor AR are.
  9. Hello Travis, This is my own idea. HKS Power Editor( can rearrange the output voltage of 3 bar sensor to the range of 2 bar sensor sent to ECU, and if offset the output voltage to cheat the ECU what the actual boost level is, the boost level can be over 2.07 bar while ECU still can take control. The boost level is a parameter to the control of the fuel delivery and sparking time. The boost level read by ECU is lower than the actual boost level, It may make the car run lean or advance the sparking time(the lower the boost is, the more advance sparking time can be), but the pulse width for the fuel injectors will be increased automatically to approach the pre-set A/F ratio. Is it a good way to increase the boost level?
  10. Thanks for the inputs. I think I will go for an more efficient C/C system as I have no idea how to tune a meth/water injection system, It could be worse at A/F ratio without a good tuning.
  11. I was told that bigger chargecooler should be paired with larger or more efficient cc rad, bigger c/c will add more turbo lag but meth/water injection won’t. Alunox c/c should be a good product but it is too big for me, I prefer the r&b one. Thx Ian, Proalloy was my first choice before but I couldn’t find any comment about it. The cc rad listed at their website is as same as yours and can be fitted perfectly without any modification?
  12. I prefer the aquamist system but I still don’t get any information about the performance on Esprit. I think the best place to mount the nozzle is the port for IAT sensor on the chargecooler for a better mix up before enter the cambustion chamber and then screw the IAT sensor into the plenum backplate for a accurate reading.
  13. Thx Chris, I don’t want to make the A/C rad as part of chargercooler rad as A/C is necessary for me in summer. when you added the meth/water injection system, had you checked whether the engine would advance the sparking timing? And did you feel a better on-boost/off-boost performance?
