thats alright

how would i go about modding my ACIS?

rather than tell you how to mod it heres a way how not to mod it

(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.

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

[BonzaiCelica]

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 ��

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.

Camshafts for 3SGE ACIS and Beams Redtop. someone from south africa told me it was $1200 + shipping, but came with springs and retainers.

http://www.catcams.com/engines/engine-sele...Manufacturer=26

Dry Sump Oil Pan for 5sfe and 3sge = $600
http://www.mr2.com/forums/threads/94399-dr...e-3sgte-as-well

Wossner High Compression Pistons 12:4.1 = $1200.

they have a branch here in Southern California....

https://www.ebay.com/itm/WOSSNER-FORGED-PIS...v-/140508110953

3SGE Beams ITB adapter plate $285, the problem is that i dont think straight trumpets will work. i think they have to be slightly angled @ 60 degrees to clear firewall.....

updates on performance parts for 3SGE

This post has been edited by BonzaiCelica: Nov 25, 2017 - 7:11 PM

[BonzaiCelica]

bump. for tuning parts....

[BonzaiCelica]

The camshafts that can be used while still retaining VVT-i are these.....

http://www.catcams.com/products/camshafts/...AMSETUP_id=2410

Please note that you have to check the lower valve seat if the lift is
more then 11.2 mm
Also check the clearance between the valve seal and the retainer like
mentioned on the data sheet.

You also have to change the springs and retainers to use this cams.

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

[BonzaiCelica]

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

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
