Part 9 : Putting 3S-GE !!!


Now it's time to put 3S-GE engine in. :)
The propeller shaft is different, so make sure you get the right shaft for the 6MT.
One on the top is one for the 6MT, which is longer than 4AT version.





While we are installing Hardrace new bushings on all the lower arm, we also reinforced the rear lower arm.
Below is pre-weld picture.




Stock bushing...




Hardrace(stiffened rubber) bushing installed! :)






Bye-bye 1G-FE & 4AT





Hello 3S-GE & 6MT!!!!




I Also got the all the used Altezza suspension/subframe.
Altezza DID had thicker sway bars compared to IS200s.
Also there are extra differential mounting point on the rear subframe.





Installed Hardrace reinforced engine mount.





Engine has been placed on the subframe.




While we are at it, we also drilled few holes on the thermostat. :)




Now time to install the clutch pedal!!
Requires cutting/drilling/welding and etc.









New Exedy clutch has been installed before putting tranny on the engine.




Had to pull the shifter and rotate because it was leaning towards RHD side.





Modified stock Altezza LSD to create some initial torque.
Left one is from IS200(4 bolts end caps), right one is from Altezza(6 bolts end caps)











The exhaust manifold interferes with steering gearbox input shaft, so we had to fabricate the custom exhaust manifold(2-1 section, no pictures yet)
Relocate the coolant line, power steering line, fuel line, clutch line and etc, then here is...Whoohoo!!!




Now time to work on re-wiring chassis harness to accept 3S-GE ECU.

Looks really good! I don't know if it's just me but some of the pictures aren't working. Can't wait to see it finished!
If you refresh, it should show up all the pictures.
The media server is also located in Korea, which causes some delay. :)

Part 10 : Firing up the 3S-GE!


Hello guys.
It has been awhile since the last update.

The re-wiring the chassis harness to accept 3S-GE was PITA!!
The problem was I was not be able to get the chassis wiring of SXE10(JDM Altezza).
The SXE10 service manual is only avail in Japanese and it IS very hard to get.



After spending DAYS and DAYS with 3S-GE Engine wiring diagram and 1F-GE Engine & Chassis wiring diagram, I finally figured out everything. :)
We did had issue with engine stalling, TRC and etc but very glad that everything worked out after many trial.

Altezza ECU does NOT support OBD, but it DOES uses VSC which IS200/300 only sports traditional traction control(TRC).
So we had to disable ETCS(Toyota's electrical throttle body), and use direct cable link to control throttle body.




Used stock Honda S2000 resonator to use on the rear muffler. Now welding time for the exhaust!








We put Personal shift knob and boots. :)




Installed power steering cooler. :)




We used Recaro Pole Position for front seats, Willans 6-pt harness, Challenge FULL-Aluminium coilovers with Hyperco springs(800lb/550lb)

















Also had to cut the transmission tunnel little wider since 6-SP manual transmission didn't fit the opening.






Seats and harness are installed :)




Now waiting for the wheels. :)




Enkei RPF1 17x9 ET35, have arrived!






The white car will be running first race day with stock engine(1G-FE, 155hp) with 4-sp auto since we spent too much time with the grey car.
ECU problems and power steering pressure issue took too long to fix.
Since the driver of the white is the beginner, we thought it would not be a bad idea to run the track with under powered engine for his first race day.

But we still installed the suspension and wheels.
Excuse the front fender since it will be re-done by bodyshop once it is all done.

RPF1 17x9 ET35 with 255/40/17 all around!!
Using Hankook RS-3 tires due to race regulation.

Part 10 continues...


Quickly we also re-made the GT wing lower bracket.










We also installed S2000 fuel pump since stock one can not support extra 60hp.






Now time to fit some nice Personal steering wheel with WorksBell GTCs on white car!! :)










Also swapped out the old riced out LED taillight with stock ones on white car.






I will post up the detail shots of the complete car soon! :)

jesus that was awesome. Love this thread. RPF1's look sick!

I'm not sure if its been mentioned but are you going to turbo the 3S GE?

Nope, 3S-GE will remain N/A. :approve:

Part 11 : Completion of 3S-GE equipped IS200!! (for now)




Here are pictures of the grey car after quick wash.
The car needs few details sort out.
Still having power steering issue, where the 3S-GE's power steering pumps out too much pressure that IS200 steering gear box can't take. :(
Anyways power steering does very little on the track, so we will just stick with no power until we find some solution.

The white car will be running the track with stock engine + auto tranny for just race day since the driver is still novice.
After the first race, we will do another conversion on white IS200 too. (I will keep posting on this car too)

Anyways were are some photos now. Enjoy!



















We detailed the car little. :)










Here are some detail shots!! :thumbup:









I will post up some more of details shots, and also continue the story on how we did on the track and etc. :)

Very nice.

I would have proposed an SXE10 body harness swap and run the digital Altezza cluster then gotten a standalone lap timer instead of running the integrated digital dash you put in.

Yup that would be another way to do it. :)

But I also like to watch oil pressure/oil temp with the Laptor R1.
It also records all the driving lines and etc for data logging to improve the driving skill.
