thats alright QUOTE how would i go about modding my ACIS? rather than tell you how to mod it heres a way how not to mod it http://toymods.net/forums/showthread.php?t...;highlight=ACIS (also I recommend a new thread for 3SGE ACIS/Beams discussion) I've been playing around with ACIS recently and I've discovered a few things about it, The basics ... when the vacuum diaphragm pulls the throttles, the larger diameter in the corner of the inlet pipes open up (under the lid) for high rpm and when there is no vacuum to pull the throttles are free to return to the constricted low rpm position. A few problems noted with ACIS: 1. When switching between high and low rpm modes, the vacuum diaphragm sometimes get stuck in the high rpm mode 2. The engage point is too late First experiment was to see how the car behaved with the throttle pull lever tied up with cable ties as to lock the throttles in the high rpm position, What I observed with the butt dyno was that under full throttle the rpm range where the car would "suddenly get up and go" was lower down, noticed in terms of road speed 65kph before, 55kph after (2nd gear) so in other words 5000-7000 was the get up and go range, without ACIS constriction in the intake the get up and go range was observed from 4000 to 7000. No loss in acceleration was noticed from idle to 3000 under part throttle, but loss was noticed under full throttle, between 3000 and 4000 I couldn't tell either way in neither part throttle nor full throttle whether ACIS was better in low rpm or high rpm mode.... This suggests to me that 4000 is a better changeover point than 4800 for performance. 4800 is an rpm not reached by normal driving due to speed limits & gear selection thus ACIS seems to exist for the purpose of keeping intake noise down at legal road speeds rather than for improving low rpm torque as midrange torque takes a hit with this setup. My proposed solution on how TO mod the ACIS, is to gutt the vacuum actuator system and replace it with a motorised cable pulling actuator triggered by a frequency switch relay at 4000 rpm the signal could be obtained by the ignitor right behind there. -------------------- Mike W

Sounds like you're splitting hairs 0.8PS (Pferdestärke) is 0.8HP or 0.588kw. Also 15-11=8.82 just stick to 1 form of measurement
Did you ever get your Celica dyno'd Bonzai to see what your base power is and go from there? So you know roughly what your gains are when you do buy & install some parts for your beams. When I installed the Tom's ecu I got a print out of the O2 readings from the exhaust. No since we have never had some sort of smog checking, I can't really compare my results to others locally. Would be interesting to compare - if it is comparable, to people in the States -------------------- |

Nope. I don't plan to do any dyno unless it's real cheap. And adding other engine parts isn't realistic. Got other plans. I was just putting the info so people know what to expect. With a full system.
Oh yea sorry. I just fixed that post This post has been edited by BonzaiCelica: Feb 10, 2016 - 2:28 PM -------------------- For Sale Items:

Not a new product or anything. But companies like technotoytuning and battle garage offer individual throttle body set up for beams motors that's actually compatible with 4age blacktop. Im just not sure if a whole kit is bolt on per say.

TRD made an second oil pan with larger oil capacity along with baffles built in and offered spacers for the oil pick up. This is probably where mr2 heaven got the idea from.

While over the ditch, NZ make these custom ones...
They can do 45mm, 48mm or 50mm Not sure on price. But gen 3 owners could use their lower intake runners, and possibly a small adaptor bracket between that and the itb's -------------------- |

I think this is a 120 degree angle, but only because it was fitted into a newer corolla that originally had an 1ZZ motor. While the one you picture looks like a 90 degree bend.

Valve Clearance Spec for 3SGE Beams Redtop
Intake .17-27mm Exhaust: .32-.42mm upgrading your transaxle to the 1994-1995 E56 trans gearing and swapping out final drives from the 96-2000 RAV4: Increase in torque from 4.176 - 4.529 is 9.24%. Increase in torque from 4.176 - 4.933 is 18.14% Which means a 4.933 final drive in your E56 transaxle will gain 27 ft lb torque + 152 ft lb (engine torque) = 179 ft lb tq more details here in this video: https://www.youtube.com/watch?v=kb3F5238fco This post has been edited by BonzaiCelica: May 15, 2023 - 1:01 PM -------------------- For Sale Items:

MAF intake adapter
https://www.driftmotion.com/2JZGTE-VVTi-MAF...pe-p/dm3584.htm Manifold flange with enlarged exhaust ports for those that plan on doing proper cylinder headwork https://www.sq-engineering.com/product/3sge...1QQm4nx2w817u3o 3sge Beams motors have an intake manifold thermal spacer. something that is not found on Honda's B18C or K20A motors. Furthermore the Beams has an improved PCV system over gen 3 design. This allow crankcase pressure to remain much lower and not push as much oil out the valve cover. These improvements were carried over to the 4th gen 3SG-TE platform despite better PCV system. blow by still occurs and oil puddles inside the intake manifold. Would recommend an catch can set up.

someone is detailing the conversion of Altezza motor into a FWD setup. https://www.mr2oc.com/threads/3s-ge-beams-b...rite-up.693735/
was told 70-72mm throttle body is a great addition to a set of more aggressive cams. however i have not seen any dyno graphs to confirm this and was told larger throttle body opening wont help much in the way of more air flow. the runners openings on the oem intake manifold are too narrow and restrict velocity into cylinder head the Caldina Greytop (auto spec only) was produced until 2002 Benefits of Dual VVT-i motor over single vvt-i redtop: Better flowing intake manifold, higher compression, exhaust vvt-i (greater flat torque curve), larger valves, different valve springs and more aggressive camshaft profile. As Far as cooling is concerned, I was told by a member who has an ST185 Celica; that his oem koyorad radiator kept engine cool on track up to 400hp. better than the dual core alloy radiator. The OEM fans are quite large and flow a lot of cfm, but come close to contacting the oem exhaust manifold. Keep your OEM (Koyo brand plastic tank header and footer) and upgrade to SPAL IX-30101522 fans. This post has been edited by BonzaiCelica: Yesterday, 01:30 PM -------------------- For Sale Items:
