Beams performance parts?? Options

[BonzaiCelica]

So i know i dont have a beams engine or an ss-III for that matter but im doing the swap in a couple of years. I was looking in the parts database. Well specifically the exhausts and headers. for all the the exhausts like the hks and 5zigen or any other ones it says that it will not fit the beams engine. the same goes for the headers. Why is that. i thought vvti only uses its main power from the throttle body. So why is it saying it wont fit with those exhaust parts. as of right now i have a magnaflow exhuast which i know is not the greatest with 2.25" exhaust piping. what size does beams engine use for exhaust piping??

Those exhausts mentioned are probably designed for the 5S-FE motor, not the 3S-GE, The flanges and bolt holes wont line up. 3S-GE comes with 2.25 if not 2.5 standard so it will be no better than oem even if it did fit, with the exception of the possibility that the exhaust pipes you have were mandrel bent instead of press bent then they will be a tiny bit better than oem. Are you fitting a beams motor? I don't understand what you mean by "i thought vvti only uses its main power from the throttle body." (???)

Well i plan on doing a beams engine swap in a few years from now and i was wondering which exhaust i could buy for it along with the size of piping i should use. Ya and about the vvti, that was my explanation of how i thought vvti. Cuase i heard people say that you have to be careful as to what type of filter you have to use on beams engine. I'm not really understanding the concept of vvt-i yet. i thought i saw a beams member with these headers on his engine

Wow those headers are beautiful, perfect shape, Love the twin catalytic converters, I'm sure with custom work that could be made to fit a beams engine. VVT-i is a design which (better than previous designs -- VVT, ACIS, TVIS) addresses the age old tradeoff between low rpm acceleration and high rpm horsepower, the tradeoff being that the engine draws in air most efficiently at a certain rpm depending on a number of factors (shape & size of intake & cams--which lift the valves, etc.) On an economical engine with low horsepower, then the engine generally breathes the best at a low rpm giving you good off the mark acceleration, on a high horsepower engine the low rpm acceleration generally suffers due to the valves/intake being too wide open for the lower rate of air that needs to be sucked in at that rpm resulting in lost air velocity, but in the high rpms acceleration picks up stronger and stronger instead where the economical engine's power would hit a plateau.

VVT-i does a fantastic job of giving you the best of both worlds by effectively altering the profile of the cams, the changeover happens a bit past middle of the total rev range.

The beams engine I think uses an air flow meter which means you'll need this silver thing in the picture here which says HKS on it with the filter attached to the end, thats the air flow meter adapter.


(Thanks to Google Image for that one)

Sometimes you get airflow meter adapters which bolt on with a plastic flange to the pod filter it comes with as a package, The one you see in the picture is the general 3" clamp type and the airflow meter adapter's end is the same as any other ram pipe, just clamp onto it

hmm oh ok then wow that made a whole lot of sense thanks for that explanation. ya if you look at this pic from the beams owner maikl you can see that his headers are different from the hks type 2 racing header. So ya know i see. And also look at his cai, it also has the adapter in the middle of the piping.

also how the hell do you put pictures in a post im not quite sure how to do it?????

Ive got a quick Question, Since VVT-i on the Beams Engine alters the Intake cam which varies the Air Flow, how does the Dual VVT-i System om the Black Top Beams Engine work, Im Assuming it does the same as the red top but what role does the Exhaust part Play?

[MercuryFree]

Isn't that the intake air temperature sensor? I thought the air flow meter sensor was located just past the throttle body? It's this way on my 3sge non-beams, but I don't see why it would have been changed at all for the BEAMS.

My BEAMS came stock with a factory header.

The HKS item is the mass airflow sensor. My motor also came with that item.

VVT-i on the exhaust camshaft helps expell exhaust gasses at high velocity in the low rpm without restricting exhaust flow in the high rpms.

Restricted exhaust means extra friction to the exhaust stroke (4th stroke) which robs engine power and high velocity exhaust gasses also reduce friction aswell as help out exhaust extraction (where the pulse of one exhaust shot creates a vacuum behind it sucking out the following exhaust pulse)

Oh I see that makes alot of sense, So Dual VVT-i notonly helps the Engine breathe at all RPM ranges but it helps it expell gases as well, But if Dual VVT-i was introduced in the BEAMS 3S-GE Black Top in the early 2000's and it creates such great power numbers why do most newer engines like the 2ZR-FE make such little Horse Power even with Dual VVT-i? is it just because they weren't designed to be such High-performance engines?
