Hi Guys, thanks for your posts, my car is completely standard. I have removed the HKS filter and returned to the factory airbox again. I now have no problems with it. Is the maf sensor the device that fits in the the induction pipe between the manifold and the airbox? If so, then I was most careful to make sure that the wiring was was in good order and that the sensor itself was fitted correctly. What I have noticed however is how much my Supra loves cold wet conditions as did my previous car, the Aristo, also with the 2jzgte motor. Does it not follow that I have less chance of getting a cool dense charge with the HKS filter than the original airbox,especially as the HKS filter breaths in the engine bay. I left the radiator mounted air scoop in place when the HKS was fitted as per instuctions. Aint this cool! Kind regards, Geoff.

Hi Darren, it does not miss a beat with the normal air box on, I first noticed a couple of days after I fitted it that she was not pulling high revs as easily. I was chasing a Mitsi' Evolution V, and the power just did'nt come in as it normaly does. It did not miss fire or pop but it was not as smooth or responsive and was hesitating which I rightly or wrongly thought was 'fluffing'. Regards, Geoff.

Hi Darren, thanks for the info also. I will try again with the induction kit and new plugs. I was a bit paranoid about damaging the motor because up till now advice was thin on the ground,most people seemed to know only about Scoobies. Gentlemen don't drive four pot motors! Geoff.

Hi Qaisar, I am aware the the vvti induction kit is different simply because DPS motorsport in Warrington sent me the wrong one first. Thanks for the info on the plugs I will most certainly join in on a group buy. Regards, Geoff.

Hi Michael, I am still running the plugs she came with from Japan what plugs would you reckomend or is it time to hit the seach button? done to The combination of Optimax and colder running plugs would appear to be the easy answer to what has been a worry for me. I have heard horror stories about the damage that has been caused to a couple of local imported Scoobies through poor fuel. I followed your link to your site, I had the poor mans Skyline 280bhp rear wheel drive only, no traction control. What fun that was, to much fun really it was like driving a time bomb! You could make fantastic statements like vanishing in a cloud of blue smoke,pop 180 degree turns or do doughnuts. A rally driver friend of mine said that it was more fun than the four wheel drive version for a lot less money. Regards, Geoff.

Hi Martin, many thanks for your reply. I think that in both cases you are right. The exhaust does seem to be the logical place to start. I have also noticed that as with my previous car a Toyota Aristo 3v (2JZGTE motor) the Supra will pink under load on a hot day. Running on Optimax stops this, so I know of all the local garages that sell Optimax. I read the thread about keeping octane booster in the car in case I am unable to find Optimax, as was the case when I recently drove my wife to Cardiff. Do they not sell it down there? Kind regards, Geoff.

Hi guys, I am new to this forum and I am no wizard with computers so I may appear a bit slow. I am the proud owner of a White 98' vvti Supra,now with 40'000 on her,18000 when we were introduced.I bought a HKS induction kit which I fitted but I discovered that she fluffed at high revs and sooted up the tail pipe and I was loosing power. The induction kit was quickly removed in case I did any damage. Would it have damaged my engine or was it my fault for not dealing with both ends- exhaust system?I do not feel that at this point I want to get involved in a new exhaust system so if this is the case would anyone like to buy it at half price? Regards Geoff.
