Need help creating parts list for 2JZGE-A340E to R154 swap for MKIV/SC
Please help me correct/complete this list. I've been researching for days and this is what I’ve come up with so far....
7MGTE R154 Transmission - make sure the tranny has the two side covers and the two sensors in it. The speed sensor is on the passenger side and the reverse sensor is on the driver's side. You can use the speedometer cable from the auto tranny, but you'll probably be better off getting the lower section for the 5spd tranny – not sure what the last part means…
Rear main engine seal- optional, but a good idea.
Rear transmission seal- optional, cheap ''leak prevention' insurance
1JZ Bellhousing - 1JZ-GTE equipped, sold in Japan only from '90 - '93.
1JZ Flywheel, bolts, pilot bearing- 1JZ-GTE equipped, sold in Japan only from '90 - '93.
R154 Clutch plate-
R154 Pressure plate-
R154 Throw out bearing/assembly -
R154 Clutch release fork and pin-
R154 clutch hub, bearing and snap rings-
Master Cylinder - from make/model/year?
R154 Slave Cylinder
Drive Shaft - front ½ from R154 any year (get u-joints replaced?) probably a good idea to change the carrier bearing now too. Be sure to align it properly when installing it too.
Rear diff- can keep existing auto
ECU - keep existing auto ECU – might need re-wiring for cruise control?
Brake pedal assembly
Clutch pedal assembly – need to cut out firewall?
Trans cross member mount – from make/model? not sure if it can mount in same location?
Trans "Wing" support brackets - 2 pieces, from make/model?
Lower and two side covers plates - 1JZ supra/soarer front inspection cover -1JZ supra/soarer side inspection covers
Have to extend the shifter linkage - there's a DIY on the forums thanks to VIPsoarer!

Shifter parts: new shifter boot, console boot, new console piece?, shift lever, (short-shift mod)
shifter bushings – there are 2 of them… 1 green (33505-35020) & 1 white (33548-31010) http://www.mkiiitech.com/forums/viewtopic.php?t=374&sid=a7198efb300e8e341a935ef8d4c9bff0
Hard line - that goes from the master to the slave, and a soft line that is part of the package; suggest changing that to a hard line as well. Brackets - for the hydraulic lines
A few other things I have picked up from posts on the forums.
The R154's main weakness is the "thrust washer" or spacer. It is nylon and if it breaks you have a floating gear so that you can not get it into first. Replace it with an aluminum one, and shift forks due to being cast pieces, shotpeening or cryotreating will help those.
There are a few wires that will need to be spliced together so that the car will start and so you can have your reverse lights. Wires will also need to be spliced together so that the power steering and ABS brakes (if equipped) will work. The Toyota wiring manual can give you all the necessary info to get these wires connected. There are some wires under the dash that will also need to be spliced so that the clutch pedal has to be pushed in to start the motor – this exert was taken from a MK3 auto to MT swap but I’m sure the same would apply for both MKIV and SC. I need help here!
Be sure to bleed the clutch system VERY well before driving the car. Bleed it as if it were a brake
system, using the clear piece of hose on the end of the slave cylinder bleed valve and pumping the
clutch pedal. Get ALL the air out of the system for the best possible feel and performance.
Some kind of pump and tranny cooler would be a nice addition !
