  1. Yes I've outwardly checked all hoses etc but thanks so much for this info I have passed it on to Rob at the Japanese car specialist where it is going next week. It's defo turbo, its just like driving an NA at low speeds.
  2. Thanks everyone, I am on it now!
  3. Does Chris have a website? Or do I message him?
  4. I've just been emailing everyone I can find, are the pistons 44.4mm does anyone know on a JDM front caliper? I have found a full kit for that size
  5. Does anyone have any interior trim panels, I will buy several for the boot interior if anyone has any. Mine were all damaged when I bought the car and I am looking to replace them. Money waiting guys and gals!
  6. I assume the brake repair kits for UK cars fit JDM cars, ie the pistons are identical in size there are just less of them? I am going to buy a set of pistons/seals etc to have my brakes stripped and rebuilt and I wanted to check as I can't find anyone selling a kit for JDM fronts. If not, does anyone know where I can get a kit for JDM?
  7. Thanks for your help guys. Ok so I have driven it significantly more and it is the first turbo just not doing much, I can go along a road and whilst the boost gauges show pressure there is no increase in speed beyond engine power, ie its linear, until about 4000 or so when I suddenly get boost. By this point I am doing 80 or so (I'm not on WOT) so I am assuming it is the second turbo. The more I drive it the more 'puddingy' I've noticed it to be around town as well, which I am taking as a sign that it is NA until second turbo. I think switching it to TTC is a bit beyond me so I am going to book it in with the Jap car specialist and get them to resolve it as I would imagine it is just a blocked line or something as it's not pluming smoke etc.
  8. No misfires, when the first turbo kicks in it does seem to pull more but not massively, but BC and gauge are both reading pressure - the spool sound is definitely quieter on that though. If carried on to WOT it then pulls at about half the rate of normal. I will drive it more today and see if I can gauge more. I would say it's running on one turbo but I can't figure out which one it is and obviously I am going to have to go a bit gingerly now. The autobox oil is bang on and was replaced when the rebuild happened so should be tip top. How do I put it into TTC? I assumed this was much more involved and I never wanted TTC as I love the power band of twins but if it helps diagnostically I am happy to temporarily do it?
  9. Yeah, the car only had a service 2 months ago, new plugs etc. It's an Auto full BPU and has even had a full engine rebuild prior to the BPU and only done about 3000 miles since, all flawlessly.
  10. Hi All So over the last couple of weeks I've noticed a small smell of petrol on WOT but no loss of power, and then this morning when I went to overtake it was like I had 'lag' and then the turbo kicked in. I am wondering if the exhaust is a little loose or if for some reaosn the first turbo isn't kicking in? on WOT later this morning it was significantly down on power overall but my BC is telling me I am getting pressure and the max is 1.12, any ideas? I'm TT 93.
  11. Cheers for your help, I have been in touch with a different mechanic and will get this plan into action.
  12. They're just the standard 3 inch decats from WhifBitz. I don't know why I just assumed the standard exhaust was 2.5 inch where it joined the back box?
  13. Thanks for all the input guys! To clarify it is a 93 MKIV TT Auto and the fail (amongst a couple of other niggles to fix) does state there is a cat missing and also emissions level fail, I believe on fast idle but I don't have it in front of me but it definitely stated missing cat and emissions high. With this said and many thanks to Annabella for the tip off allowing me to buy a second cat last night .This should be here tomorrow and I already have the first cat from my original car so I am going to have these bolted back on and it should then pass both stipulations. My only question is do I need any kind of adaptor to bolt it back on to the rear section? Obviously the two cats will fit to the manifold and each other but how do you connect a 3 inch rear section to the end of the second cat? What type of adaptor is required or does it just fit?
  14. Are the normal cats 2.5 do you know? And will I meet the emissions with one fitted? Also has nobody produced an exhaust system with a race cat or cats fitted that I can just buy and leave on for BPU (ish) performance? I don't mind spending some wedge to do this.
  15. Hi All So my BPU decatted Supra (93 TT Auto) has just failed it's MOT on emissions for the first time ever. It's been BPU 3 years but I guess I got a real stickler this time. It has a 3 inch exhaust system with straight downpipes. Is there any 3 inch race cats that run BPU but pass emissions that anyone on here use and if so what sort? Any help you can give would be MUCH appreciated as I am off the road now by law!
