We know the 2016 2.7l 2tr-fe engine in the 3rd generation tacoma has been changed. We know the compression ratio has been increased from 9.6 to 10.2 and the engine now has variable valve timing on the exhaust side giving it DUAL vvti status. Toyota leads us to belive that the new engine has (been detuned?) to the exact Dual VVT-i FJ Intake mod for Tacoma Single VVT-I engines. Discussion in '2nd Gen. Tacomas (2005-2015)' started by Key-Rei, Sep 15, 2017. Post Reply. Page 3 of 3 < Prev 1 2 3. The FJ/4Runner (Dual VVT-I engines) throttle bodies are a few mills larger than the single VVT-I TB's. The intake plenum opening is a larger bore than the OEM Tacoma Smaay - there ae 2-3 versions of the 1GR. the newer ones have dual VVTI, he older ones single VVTI. I have seen people running 4psi boost on stock injectors and ECU for 320 /360 whp/ ft/lb but there is also the TRD larger injectors + reflash option used for the TRD SC. I am unsure if there is a difference in the FJ vs the tacoma / tundra Wrong.". "The stock 1JZ bottom end is good for 650-700, which is 260 - 280 hp/liter (650hp/2.5liter=260hp/liter). The stock 2JZ bottom end in good for around 800, which is 266hp/liter.". "Both of these engine's bottom ends have been pushed way past the numbers I've just quoted. neko. I think, when it comes to the mr2 engine compartment, its the Dual vvt-i head thats the problem. The cam setup interferes with the strut tower. at least that seesm to be the commonly held belief. however, the beams/4th-gen 3sge head has single vvt-i. Mods: Alpine audio, Aeroware front, sides, and spoiler, custom rear, 94+ Tailights, K&N To really see the benefit you'd need the matching ECU, or something custom to control the second ACIS valve. That would make sense, the twin throttle body has an oddly designed 2 chamber interior that seems designed to allow something like that. '99 1MZ A541e Camry @ 350,000+ Abusive Miles.

The "red top" can found in a JDM Celica and MR2 and also FWD (MR2 not FWD, but you know what I mean). The "grey" and "red" are basicly the same with one difference. The "grey" has cats built into the header. Vanos (or variable Nockenwellensteuerung) is BMW's take on VVT and was first introduced on the M50 engine within the 5-series of the 90s. It also uses cam phasing but with a helical gear within VTEC is developed by Honda whereas VVT-i is developed by Toyota. The VVTi only alters the timing while i-VTEC alters the timing as well as the lift of the valves. The VTEC makes changes to both, the intake and the exhaust valves. The VVTi technology on the other hand works only on the intake valve. aPuRn2.
