where is the parts list that lists all the parts that are needed to do a 1jz conversion??
Like which motor mounts, what oil pan and oil pump or the pick up, drive shaft. you know, all the odds and ends. I found a motor withh trans from a supra for 1999 plus 170 shipping. So unless you guys want to see a SR20det in a cressida, you all better help a nugga out. a list withh actual links to order the parts would be awesome too.

this site is cool: http://www.1jz-gte.us/
and this one is good too: http://www.jzx81.net/jzx83

front sump and all the parts including the turbo oil drian
jzx81 mounts as complete as possible, I used JZA70 rubber mounts with jzx81 brackets, but I think you could make jzx81 brackets out of steel if really needed.
1990 V6 4Runner throttle cable
jza80 waterpump (optional, eliminates hydro fan oil pump and increases reliability)
all the things on the engine that need service when you get it (oil hoses, coolant hoses, belts, turbos, etc..) may need service.replacement
I got a $350 driveshaft at driveshaftshop.com, sorry I forget which one works with the factory hanger bearing.

if your car is already running well (minus the motor) a JZ swap will be easier. My swap is taking forever because I started with a rusted $900 parts car and have to replace everything.

mine's using stock (new) cressida rubber mounts withh JZX81 brackets, it's real nice for the street but it might be too soft for your drifting skilllzzzz. zero engine vibration though. if i'm not mistaken, the 91-92 uses a harder rubber mount than the 89-90. also get a supra half shaft for the R154, use the stock driveshaft. brand new 2JZ pump is a good thing to start out withh. non of that hydro fan mess... less stuff to break in my opinion and the clutch fan works fine

Yeah most of the stuff thats been mentioned. I used a lot of the JZA stuff in doing my conversion but LHD will have slight differences.

Main things are the 2 sump peices, windage tray, pickup and oil drain.
JZX81 engine mounts or alternatively JZX90 mounts work if you put them on backwards.
instead of replacing the pump I bought a barb fitting that screwed into the water pump outlet and looped the hydraulic lines.
standard MX83 transmission mount will work on the R154
From memory you're already 5 speed so pedals arent an issue. might need a clutch line to be fabricated.
I used JZA70 throttle cable but im RHD
and as mentioned before replace all the hoses and clamps withh the engine out of the car.
Also if your budget will allow for it, fit an aftermarket ECU as well.
Ditch the stock intercooler as well.

i think it's easier to fit a larger intercooler upsidedown and route the pipes through the radiator support... unless you have the complete JZX81 clip to swap parts over from... otherwise the JZX81 intercooler won't fit withhout some modification if i remember correctly...

edit* found the post

anyway for my parts list:

jz-r154 bellhousing

r154 = 3lb sledge and an hour on your back under the car.

driveshaft = 5sp mk3-T front half, mx83 cressida rear half

engine brackets = jzx81-90 specific. pitmfa to get. if you want me to fab you a pair its gonna cost but speak now before the motor is in the car or forever hold your peace.

rubber isolator mounts = new toyota. WAY TOO EXPENSIVE. check rockauto.com first... about $60 per as opposed to $112 per. if you are strictly track make your own solid mounts.

intercooler = free starion cooler for now. cxracing (really nice shit i got off ebay for hella cheap) gonna replace it sometime around when the turbos let go and i do a big single :P

downpipe = ausie made jzz30 DDP. clears stock mounts no problem. hope it clears the fenders and frame rails too. PS: FS when stock turbos blow up :D

clutch = gripforce F1. ebay special. 6puck sprung hub. hella heavy (i guess the stocker is too) rated better as far as tq and hp handling than comparable ebay special.

boost gauge = used pivot off ebay. hella cheap. pivot makes good shit. this one has seen better days but the gauge and light still work.

RAD = plastic endtanks suck, but otherwise stock rad is burl as hell. ima rock it for a while and see what it does.

PS lines = use the stock jammies, just bend them to the propper location. otherwise JZA80 works.

AC lines = ehhh im probably going to have to take it to a AC shop to get the lines done right. im gonna try to bend them to shape first. mx83 lines point in completely different directions than the 1jz's though

clutch pedal = looks like im hittin the junkyards tomorrow looking for a NA mk3 supra, for the pedal and clutch master. anyone else using this pair to drive a r154 clutch slave? for the hydro line, just get a length of steel tubing, bend it to shape. deal with getting a softline....either use the stock supra softline or get your own shit made to length at a hydraulic shop.
