3sge into 1994 celica help

[hachi-rocu]

I am looking at getting a 1994 Celica Gts. The motor is blown and I was hoping to put a JDM 3sge into it (TVIS version). I know that I will need the motor tranny ecu and wiring harness to make it work so far. I was just wondering about what to do for the fuse box and would all of the guages work.

If anyone could lead me to a site about this swap it would be appreciated. Thanks for all your help!!!

try look for a all trac fuse box...any other questions

Personally... If I were to go through the hassle of an engine swap... I wouldn't swap in a 1st gen 3SGE. That engine isn't much better than a 5SFE (stock for stock). it does have build potential over the 5SFE... but aside from that... no major advantages. I'd reccomend you go with a 3rd gen 3SGE or something... at LEAST a 2nd gen 3SGE.

The reason for the first gen is because I have a friend who can get japanese motors. This motor can rev higher has 160 hp and a big aftermarket support. The 3rd gen is out of reach for me and even though the 2nd gen has a little more power I like the TVIS system and with some bolt ons I could get them to equal in power. I am not trying to build some huge turbo motor either I would prefer to go the high compression route. Either way I would be happy with around 200 horse.

I think you're mistaken, the TVIS 3SGE is the first gen (130HP), the non TVIS 3SGE is the 2nd gen (153-160HP.)

[allblackalltrac]

I think your both mistaken...1st and 2nd gen 3SGE incorporate the TVIS system it wasn't until the 3rd gen they eliminated the TVIS. 2nd gen utilizes a dual plenum design IIRC. Also there was a 160HP 1st gen 3SGE designated 3SGE(LU) high output. It used a higher compression piston to achieve the higher output HP and a more aggressively tuned ECU. FYI if you go with a 1G 3S get the 2G 3S exhaust header, small port, long runner design and if you opted for the 2G 3S use the 1G 3S larger port, short runner exhaust manifold.

why do you want to stay NA? why not go for a 3sgte? much more potential with a turbo...

i would do what wraith suggested and get the fuse box that goes with the wiring harness. if not, you will have to splice all kinds of wires to the correct types of relays and fuses... and there arent going to be any detailed schematics of the fuse box from the JDM motor...

Are you talking ST16X or ST18X engines?

There were several different versions of the 1st gen 3SGE.. yes 130hp, 150hp and 160hp (160hp is overrated IMO). The difference is not in compression, it's purely ecu tuning and emission restrictions. The 2nd gen 3SGE which came in the ST182 (amougst others) had NO TVIS. It was a smallport head design and used a completely different intake set-up. It had higher compression and power was bumped up to 155-170hp depending on who you ask. The 3rd gen came in the ST202 (amougst various others) and had even higher compression and eliminated under-bucket shims (~180 hp). 4th gens are the Fabled BEAMS versions... although I'd consider the Altezza BEAMS 3SGE a 5th gen model... Each version in essence had a completely different head design... TVIS is not for making power.

*AHEM*... er... lads.... 2nd Gen 3S-GE never used T-VIS, this system was replaced by a system that worked like T-VIS but was much more efficent and it's called ACIS (Acoustic Controlled Induction System). 2 short runners on low RPM and 2 long runers that open on "higher" RPMs (usually 4.200 RPMs). I had the engineering paper written by Toyota on this ACIS thing but not the link to where I got it from.

Here is an brief part of the doc.

"Acoustic Control Induction System
The Acoustic Control Induction System (ACTS) is used on the 7M-GE, 3VZ-FE, 2JZ-GE and other engines. As with the T VIS system, the pur pose of this system is to improve engine torque throughout the engine rpm range. The system consists of the same basic components as T-VIS and operates similarly. The ACTS system uses a single intake air control valve located in the intake as chamber which effectively changes intake runner length as it opens and closes."

It continues to say "The main difference between T-N'IS and ACTS is the single butterfly air control valve used in the ACTS system. This valve is located in the center of the intake manifold plenum and is designed to divide the plenum into two sec tions, a front chamber and a rear chamber. By dividing the manifold plenum into two cham bers, the effective manifold money length can be controlled by opening and closing the valve." and "The ECU controls the position of the intake air control valve based on input signals from throttle angle (Vta) and engine rpm (Net. The VSV which controls the vacuum supply to the actuator, is normally closed and passes vacuum to the actuator when it is energized by the ECU."

Hope it helps

I know the first gen JDM 3sge has 160 and the north americain one has like 135.

I dont know if the Japanese one gets its power from compression because I have several japanese magazines that say it is 9.2:1 like the north american version. I have heard different compression numbers from different places.

I know alot of the power is gained through the ecu and the different emissions systems.

The reason I want to stay N/A is because it is different and something that I can build up to redline at some stupid number.

The consensus is that the 2nd gen engine is much better than the first, the work is about the same amount, and the cost is only a few hundred bucks more.
