I'm looking seriously into this now, but a quick couple of questions I know the ae111 ITBs fit fine (with adaptor) but do the ae101 ITBs fit ok too? (the reason i ask is the ae111 ITBs are hard to find around) 46mm Vs 50mm size, does it make a big power difference. from what ive read it shouldnt unless im hoping to make huge power gains (which im not) and lastly, can I still run the dual VVTI with the ITBs when i run an aftermarket ECU, cheers guys. |

To be honest I see more BT ITB's avalible. TradeMe / but if your not already over there, Toyspeed. Members sell / trade usually has a couple a month. Trademe prices from 150 - 400 dollars. I'd love to do this much later but knowing I'll need the right ECU and tune it sounds like a savings mission. But yeah 3 sets of ST ITB's on trade me now

hell if you can find some BT available now, send me in that direction. there was one i was looking at, but sold it outside of trademe. (prick) ---EDIT--- cant register for toyspeed now unless you have a paid email address. so thats me out anyway. |

Could try T-Parts, just a tad higher than the average price (not by much for a wreaker) they have a good stock usually on the 4age department. Guess it depends on how baldy you want them at the end of the day. Good luck I'll keep an eye out, the ones on my blacktop are required by me :lol: |

It'll cost $3-4k minimum to get an ITB setup working with dual VVTI. That's an expensive 20 horsepower! |

I didn't want to post it. dyno before with all ducks in a row to have a measure against final gains. ITB's: Fabricate adaptor plate Aftermarket ecu correct linkages MAF sensor Custom made plenum Custom made trumpets ECU installation & tuning Dyno after the fact to prove gains. I'd say closer to $5500 for a final result being conservative if you cannot make half of it yourself. I'd be in this category but my mum's partner is a steal fabricator / engineer, he's always slapping steal on something his Ute, parents trailer Only thing I will say is "unique" better sounding than a turbo (IMO). Better throttle response and its not all about how fast you go in a straight line that matters so comments of "go turbo" while expected may not be what the OP is looking for. Gain's would be WELL more than 20hp if tuned correctly. I imagine combined with a TRD solid flywheel/clutch system it would be rather fun. Ahhh a harmony of four trumpets singing together is something special

Just wondering... Can you have both turbo and ITB together?? |

I'd say yes however I'm not expert on such things but another guestimate would be that it would likely require a highly skilled tuner. |

Its been done but your going to need to be one rich dude to pull that off and would not be suitable for the street. |

Yes can definitely be done with the use of an intake chamber or similar. RB26DETTs use individual throttle bodies from factory |

im not really in it for the extra horsepower. for me its all about response and pleasure to drive if i wanted big power i'd rip out the 3sge in seconds.
convieniently my brother is a stainless fabricator and my boss built his own 400kw monster. so that wont be a problem.
are you saying that quads wouldnt be streetable? or are you talking quads and turbo? |

He mean's I believe, no low end, you would be braking the law every time you put it on the road i.e. impractical for road use (correct me if I'm wrong).And if your serious, I 've got a response on another forum. |

breaking the law? theres plenty of cars running ITBs that are road legal. yea im serious, its something im wanting to do. if i tune it right i wont lose that much low end. |

Nope I confused myself, that was CLM877 asking that question
Trumpet length, but again it's probably been proven what lengh to run with already, track and street use are really two different things. And yup, seen that beauty, I'd cry if it got a stone chip in the bumper

There's not necessarily ANY power gain from quad throttles, you could just as likely lose power. An S2000 makes 250hp with a not overly amazing looking cast manifold with single throttle. Altezza has a better factory intake manifold design than an S2k in my opinion. I had a full quads setup good to go, but found that power/response/etc was great with the single throttle setup, so sold it. "CelicaRA45" did some back to back tuning with quads or not, ~20hp improvement when in conjunction with aftermarket ECU if I recall. Bear in mind that in order to gain 60hp, the TRD engine needed revised pistons, rods, cams, quad throttle setup, exhaust manifold, full exhaust, ECU. You're not going to get 30-40hp from just Quads. |

Its all relative, you wouldn't install a turbo without the supporting mods, neither would you just bolt on a 3-5k setup without exploring the potential elsewhere. But yes that statement is correct, tumpets alone won't yeald much but sound. We all know forced induction is the cheapest means to build horsepower, it's just not everyones cup of tea ![]() Don't get me wrong roman, I actually appreciate the feedback you give, generally helpful

if you just bolt them on and dont tune it then youll never make it better, but tune it correctly with an aftermarket ecu and there is an improvement. again, im not looking for HP improvement. im looking for a car with a good response and something fun to drive. celicaRA45 had his engine up to 180-ish KW atw with all his improvements. id start with quads and ECU (with proper tune), then pair it with a less restrictive exhaust system later on. |

I was referring to itb plus turbo. It would be hard to keep the noise to a minimum |

Yeah I'm not bagging the idea, quads are great. My suggestion would be that if you use the 20v throttles, do so in a way that keeps the two stage throttle actuation, to open them at a non linear rate. Car will be much nicer to drive when just cruising that way. |

my mate/boss that built his supra up has wicked contacts to get the link g4 stupidly cheap. aparently you can tune it to run in a standard state, then with throttle hard down switches to a more agressive tune. i dont know enough about this sort of thing, so am looking into that more closely. |
