variable valve engine comparo

[alwayz_yummy]

sa akin lang, honda is good naman, pero way too madami na sa road natin, which somewhat i dont like...b16a, vtec, parang word of "filipino" mouth na yan...

pero in fact, 2 cam lobes lang ang vtec, MIVEC, 3..pero needs high octane rating. 4age silver and black top is not as noisy as honda b-engine..now k-series engines na ata) personally, i havent seen a SR16VE, nadidinig ko pa lang siya, and 2 years ago ko lang siya nalaman.. ang alam ko lang is SR20VET! the first turbocharged VVT engine, 2.0L rated stock at 280hp!

by comparision, nissan makes first in in VVT technology. just like in CVT(continuosly vaiable tranny). actually, a honda fan again will say una ang honda, well infact, JDM sentra and serena models 1998 is already using it, and ga16 and sr20de mga yun, not 1.5 and 1.3. take the murano, v6 3.something, pero CVT, mga year 200 pa ako nakakita ng USDM models, na happy to say pareho dito...pero OT na yaung CVT..VVT topic ko.

purpose ko nito, is research. if ever i will get a honda, ayaw ko ng kapareho ng typical honda fan..mitsu, subbie, mazda and nissan fan ako,e...recently lang ako naconvert sa toyota..honda, well, CR/HR-v and odyssey, lang...but trying to pit in somehow...may honda tuning ako na libro dito, vol. 1, includes swapping guide from civic EF-EK, inluding CRX and del sols, accord 92-2000, also prelude..kaya madami na akong guide for honda..but how does the other VVT engines pit in against the loud honda vtec?

ang isa pang gusto ko sa VVT engines, mostly NA siya, no turbo lag, and fast spinners: 7000+rpm redline... may VVT engine ba that goes 10,000rpm(max) honestly.

pansin nyo mga recent threads ko, ung civic shuttle, mazda astina/lantis, wira hatch, corolla wagon consider ko din, cheap wagon/hatches..may maxima din ako(na coconvince ko nalang si mami na wag ibenta, kasi nadesisyonan na nya) swapan ko sr20ve/sr16ve..20det, parang common na masyado, pero ok din.. e..

*loud-->di yon tunog ng makina, loud i mean is yung masyado siyang bukang-bibig, lalo na ng mga wanna-be and boy racers..i'm glad dami inputs about this here. locally avail vvt engine din habol ko (honda b-, 4age20v black/silver), MIVEC, ung SR16VE baka walang makasagot kasi uber rare dito sa atin yan, sr20ve, ganun din ba?...of all VVT engines here sa atin, nissan is the most silent one. parang tipong enthusiast talaga nakakaalam..

nabanggit din as ot yung cvt...

tagal na subaru nagtry with a cvt, sa 1980 justy ata yung may cvt. heheh.

[alwayz_yummy]

sure kasi na local honda fanatics will also brag CVT as their first.

i never expected these replies nga e...just keep them comming.. also, para din ito sa mga gusto malaman kung anu ang VVT engine advange/disadvantge between the manufactures, not just honda/toyota/mitsu...so including din mga european & american cars(if the americans use VVT..)

[nugundam93]

ehehehe.

hmmm...i have never heard of any pure american engine that used any vvt system. meron nga ba?

back when the nsx surprised ferrari, they responded with the f355 and when asked why they did not use a system similar to vtec, they said that their 5valve/cyl system was superior to the vtec. read it in a road and track issue where they first tested the f355.

[nugundam93]

that is also what I LITTLE understand about it. I am not sure but I read that is why people use racing chip for their Vtec to make it aggresive from the start. meaning a factory tuned Vtec is intentionaly designed for Economy...

not an Engine Expert, but in Movies, Games and real Test videos, mas na-uuna po yung Nissan GTR Skyline. I have no Idea what kind of engine design ba siya... basta 2.7L :lol:

they probably just lower the vtec activation point...?

the GT-R uses a 2.6L twin-turbo straight-six. aka RB26DETT.

[nugundam93]

bakit hindi dinala ang mga engines na yan dito?

ang gagaling ng Japs when it comes to extracting power from NA engines.

hindi ba ferrari owns the highest HP/Liter at the moment? not sure kasi ako eh.

pero true, the japanese can pull some big numbers too.

***edit***

FXX vs '06 S2000: 127.75 bhp per litre vs 125.19 bhp per litre respectively

[alwayz_yummy]

alam ko nga non-vtec ung 1st batch ng nsx....kaya ko dinugtungan ng "if americans use VVT"...knowing them.... nothing replaces displacement ika nga...pero european and japanese, including koreans use vvt in almost new engines nila...

rb26dett ang gtr, pero non-vvt pa to,rigth, just like 6a13 ng mitsu, only v ang mitsu...IS200 i think is a vvt engine na..straight 6 2.0/3.0L RWD!

hay the advantage rich oil-consuming countries!

[nugundam93]

right from the start eh vtec na yung nsx. iirc ito yung 1st mass-produced application ng honda f1 vtec.

lemme recheck the tamiya 1/24 NSX manual. andun yun eh. :D

[alwayz_yummy]

may nsx ka pala!

subbie lang sa akin,e ung black 22b WRC!

may bad pala kung sakali....cheap ferarri and nsx,e..

[nugundam93]

i actually have that poor nsx in pieces. i painted it in car paint kasi, it went bad, so i soaked it in thinner. ayun, lumutong yung plastic and as i was scrubbing the paint off, it disintegrated

ehehehe OT post. :D
