  1. ok, i will try a smoke test from my mechanic ... hoping it can help solve the mystery I noticed, however, one thing .... disconnecting my HKS ssqv bov, and blowing inside the tube connected to it, the air does not remain sealed but vent a little ... (I blew with my mouth not with the compressor) , is this vent normal? or in any case at low pressures should they be completely sealed?
  2. hi guys, Unfortunately the supposed air leak is not coming from the vacuum hoses (none are damaged, or they were inserted wrong, all clips were tight) ... Only thing that is left "old" 20 years is the HKS ssqv ( I bought the kit to regenerate the internal o-ring, and a new reinforced silicone hose ). Regarding the temporary TTC mode, I had a doubt ... that is, even if I did it, it would allow me to know if there is any solenoid / vsv not working well, but not that there could be a air leak, and, above all , where it comes from .. I'm going crazy: \
  3. The hose are all BF Goodridge, with high pressure and heat resistant (with the rope texture inside them). the silicone couplers are by Whifbitz. Since i have the JDM spes i change the oem BOV with HKS ssqv one
  4. what do you mean by the two link pipes between turbo and intake? are you referring to the aluminum pipes or the rubber pipes that connect the aluminum pipes? because I have also replaced the original rubber pipes with silicone one(which could swell and block the flow). In addition, the turbines received the modification to the core assy by SRD, so no more ceramic assy, to withstand even the 1.2 / 1.3 bar of boost. I had read something about the temporary modification in TTC, but from what I understand it serves to rule out any problems related to the solenoids / vsv. I had thought of proceeding in steps, first check that there are no vacuum leaks, and if all the tubes are ok, proceed to check the solenoids. I'm going crazy looking for a method.
  5. ok ... I will try to hear if there is any leak from any pipe or duct .... and I will double check all the vacuum pipes. Could problems with the solenoids and the Vsv be ruled out?
  6. Hi guys, I started having a little problem on my Supra S2 (2000 late model, 2jz-gte VVT-I, 6mt., JDM Spec.). as for the changes it has totally stock engine, it has only a full bpu with Mine's ecu. The engine has approximately 67,000 km. Suddenly he seems to be having trouble reaching maximum pressure in full boost. Normally it reached 1.2 / 1.25 bar of boost, while currently it can reach 0.98, sometimes 1.15, other times 1.08 .... Even the speed in revs seems more "sluggish" than before, but beyond that it has no grumbles, it has no progression failures ... in short, it seems "alone" with less hp Even at idle, the turbo pressure gauge, which normally fluctuates between -0.4 and -0.5, is now fixed at -0.6. In short, it seems as if there is an air leak, but about 6 months ago, all the vaccum tubes were replaced, with new clamps as well. Clean all the pipes, clean the intake system and change the filter, change the spark plugs .... etc. the car was fine, and after a few months it is showing this problem. What could I check? could it be the solenoids / VSVs? Thanks in advance guys
  7. I have carefully read all the pages and also others on the Lexus forum ... they speak of compatible models, but no one indicates the oem part number for the various spare parts, and, for example, for the 3.615 ratio that I am looking for there are 3 codes different (including two for the same models / years): 41201-59055 41201-49135 41201-49125 .... I would not want to spend several money and then discover that they are not compatible
  8. it is really difficult to find a UK / Euro differential with 3.58 (bif diff) and if it is found it costs a lot, plus I would have to change the drive shafts (mine is a jdm with small diff A03B). So I wanted to buy only the crown and pinion. the difference between my ratio 3.26 to 3.61 is about 10% (3.78 seems to much on the TT with v161). the problem is to understand which is the correct part number for the lexus 3.615 r&p spare part
  9. hi guys, I am a Toyota Supra owner and I live in Italy. my Supra is a 2000 m.y., JDM spec, 2jzgte vvti engine, V161 / A03B trans / diff. Soon I will rebuild my diff. and I wanted to shorten the final drive, by installing an R&P in 3,615: 1 (currently I have a full BPU, 18 "wheels, and I don't care about top speed but to have more acceleration). Having said that, I have read everything on this page and something on the Lexus forums too, but unfortunately I have not found the answers I am looking for, and before I spend any money, I hope someone here can help me. Consulting Toyota / Lexus EPC I found this out regarding 3,615: 1 compatibility -41201-59055 (500usd): Toyota Celsior (UCF30 / UCF31-3UZFE) Soarer (UZZ40-3UZFE); Lexus GS430 (UZS190-3UZFE), LS430 (UCF30-3UZFE), SC430 (UZZ40-3UZFE) -41201-49125 (720usd): Toyota Century (GZG50-1GZFE); Lexus GS300 (JZS160-2JZGE) GS430 (JZS160-2JZGE) LS400 (UCF10 / UCF20-1UZFE) -41201-49135 (502usd): Toyota Century (GZG50-1GZFE); Lexus GS300 (JZS160-2JZGE) GS430 (JZS160-2JZGE) could you explain to me the differences between these R&P? Anyway which of these is 100% bolt on on the Supra's small 8" diff? I also read that some R&P, despite being adaptable to the Supra small diffs, are "thinner" in the crown diameter and must be flanged Thanks in advance
  10. Hello to everyone, I need your help... I am installing the greddy profec oled ebc, and I would like to have some advice on which is the best spot from to take the boost pressure source to power the greddy oled control unit, not the solenoid. for now I have used a "T" fitting on the OEM pressure sensor tube located on the intake manifold (from the side that gives on the valve cover; many peoples use it as a source for the boost gauge. ic attached). but I would like to find a different, more reliable and direct source (the hose is only 1/8 "and therefore it could blow away). Furthermore, the greddy manual says:" For Toyota's JZ engines, Mitsubishi's 4G63 engines and engines with fuel pressure controlling solenoids, make sure to tap the pressure in between intake manifold and fuel pressure control solenoid. (do not install on the line between the fuel pressure control solenoid and fuel pressure regulator.) ". what other source can i use safely and reliably as a boost pressure source?
  11. Many thanks....and Do you know of any company that makes a rigid collar to install instead of the OEM one?
  12. Hi guys, I am owner of a Supra jza80 TT, JDM spec, v161 and A03b differential. Since I have a second differential A03b that I don't use, I want to use it to mount a 2-way lsd, and a shortened final drive. I wanted to know if it is possible to install the 3.77 final drive coming from the Supra differentials of the model with automatic transmission A02b or A02a. Are they completely plug and play? alternatively do you know of some site where to find the final drive for A03b and the relative rigid collar to use instead of the original one? Thanks in advance
  13. in fact I can not even understand if it is a widebody or not, and who distributes it can not tell me much more (and I can not find information around). I would be interested to understand if it can be installed on the original front and rear fenders ....
  14. Hello, does anyone know who makes this body kit (manufactur or dealers)? http://topbodykit.co.uk/p/5074/toyota/toyota-supra-mk--body-kit It seems like a TRD copy one. I would like to have more info about this, some reviews or other that can help me to know somethings about quality\fittings ecc.... thanks
