I wanted to know something. When you remove the torque plate (auto flywheel) there is a spacer on the crank. In other words, it is sandwiched in between the torque plate and crank. what i want to know is, do you have to remove it when you install the manual flywheel or do you leave it on? To clear any confusion, it's about a 1/4 inch thick, removable and has 8 holes just like the crank.
hey. just spoke to john. verbatim, "throw it away".

and for the pilot bearing question you had, he said there is an installer that you use to install is, and you put it in till its flush.

I'm in the middle of the R154 install and I ran into an issue. I need to know exactly what I need to do when it comes to mounting the tranny mount and crossmember. I have 3 mounts I can use (R154, IS300 manual, IS300 auto). The R154 mount bolts just fine to the tranny but doesn't bolt to the crossmember (the holes are closer together plus it has a big nut at the bottom of the mount that doesn't let it lay flat on the crossmember. I would need to elongate the holes and then drill a huge hole in the middle of the crossmember to allow that big nut to pass through so that the mount lays flat on te crossmember). The IS300 manual mount bolts just fine to the Crossmember but not to the tranny. I haven't even tried the Auto one. I already know about the 3/4 inch spacing. Please help!

anything yet roy?

i think this is what you should do:
take a steel block, like 1" thick, and whatever size is similar to the stock crossmember, let's say 12" x 4".
then you can drill whatever holes you need that match up to the R154 mount.

then take two more small pieces to use as spacers. probably like 4" x 1" (wide) x 3/4" (high). and you drill two holes in each that lign up with the holes in the body of the car to bolt up the crossmember.

i think that's your best bet. your buddy should have no problem doing this, honestly. this should be the least trivial thing of the whole swap, you've already done all the complicated sh*t!

I know imagine that, I have done day's apon day's of research and I am getting stuck on something like this. It just comes to show you that you can always do more research.
Well I think the car should be done within the next couple of day's.
I will be looking foward to giving my review.
Thanks Leon!

marlin re-did there site recently

there are a lot of people on the forums here that have had their tranny rebuilt by them...i'm sure they can chime in

in a few months i'm taking mine to them, i've talked to them on the phone...and they said they haven't had anyone return that they have built a tranny for...and they make the tranny pretty bullet proof

i've only heard good things

Hey LO how's the car driving? how's the clutch feel?

i think my plans for boost are going to be an R154 with a Aristo GTE eventually. i just like to see how yours feels now.

Also as far as Marlin goes, the link i posted says they require a core exchange. so should i try to find a decent shape R154 and send it to them to see how much that one would cost? or buy one that is blown and send it to them to be rebuilt? i guess it would be better to call them and talk to them huh? lol.

yeah...call and ask them to make sure
i have a blown one that i'm going to send them, but i just have to get the money to do it (1200 + the shipping of your tranny both ways)

if there are parts from toyota that they need to order...they'll put them in and charge you

ps...anyone feel free to correct me if i'm wrong, as i don't have the money quite yet, i haven't covered all the angles on this

well see this is what i was thinking. if i'm going to have to pay 1200 + to have it rebuilt then why spend more up front. as in why pay 500 for a decent r154 when i could pay 200 for a blown one. does that make sense?

i have a friend that works at some kind of parts store that deals with used parts and he said he could get me one. i'm just waiting to here back from him, but he said it would most likely be pretty cheap.

i just didn't know what the difference would be in sending them a decent one and a blown one. or how they do the core thing with the one that i linked above. but i'm sure if i call them all my questions will be answered! lol thanks for the help though.

Well, that sucks. I live in a county where I need to pass inspection. Would you happen to know what the codes are that came up? If these are codes which will keep me from passing inspection I will have to scrub the swap plans (sucks even more, since I already started purchasing parts).

Side note. I keep hearing everywhere that the R154 is also used in the Saturn Sky and Pontiac Solstice. I know there is parts sharing between GM and Toyota, but I was surprised...

Solstice/Sky 5 speed manual (man, that is a long extension).


R154 from this thread.
hey, well this questions probably been asked before but i'm looking into these tranny's too but i heard that on some of these tranny's, you have to extend the shifter farther... from the top one, it looks too far for our cars... the second one look perfect but then most of the tranny's i run into have the shorter extensions... which tranny's are those?... are those from the supras?

yea the top one is off a pontiac that recently began using an R154, but their shifter housing is totally wrong for the IS.

the bottom one is the one i used, its a post-'94 soarer/chaser tranny from japan. they pop up every so often and a decent one will run you $1200-$1600 (and if it doesn't come with the 1j bell housing then you'll need that as well obviously).

the more common R154s you said you've been running into are off the '86-'92 mkIII supra. those will run you $300-$800, and will work with NO shifter housing modification as long as you use the '92 SC300 shifter.

my buddy that i made this thread with (DC5ROY) finished his swap today, so he'll probably be posting pictures of how a regular R154 with the SC shifter sits

and i had forgotten to post pictuers of my finalized center console
probably will just get a momo or sparco shift knob but besides that it turned out great. shifter location and height came out perfect after modding the shifter a bit.

a lot? haha relative to what?

how much are you looking to spend then? averaged out, i ended up getting every single part for about half of what it retails for if you get it from the dealership. my tranny costed me 1200 with a shifter. and i ended up getting a great deal on my 6-puck which costed me wayyy less than half of what a twin disc woulda costed me. the only thing on my swap that coulda been cheaper is the tranny, which if you get a normal one for 600 and add a $200 shifter, mine wasn't an exaggerated amount more ;-)

if you're not prepared to spend at least 4 grand, probably closer to 5, i wouldn't do the swap yet.
it's quite an easy project to do if you have someone that knows what they're doing, but there's TOOONS of parts. look over that list in detail and maybe put it in a spreadsheet so you can properly plan out your swap, what parts you have left to gather, and how much it might all cost you.

as of right now, i'm just looking into it... I dont have the funds nor the brains to do this right now... haha... so i'll gather up my knowledge first and maybe later down the road I might just make this my project... its just all very interesting to me right now... but yea... i'm diggin it a lot tho...
