I'm not going to write any prices. That sorta stuff has too many variables. I gathered these numbers so others wouldn't have to search for hours just to do a simple comparisson. Feel free to post how much you paid for your swaps and who did them. Add more to this thread if you feel the need. Links to other threads would be great.

you might want to put in the SUBJECT of this thread:

IS300 and SUPRA engine/transmission specs

otherwise, this is information that has been posted and plastered all over the internet on other forums as well...

yeah change the subject this is useful info... but but most people will assume it's another already been answered question from a lazy person and just ignore it and not even open it... good info though! should also add 98+ VVTI GTE specs though If you're going to have everything else... unless they are exactly the same just + VVTI... but that I don't know so I won't speculate I'll just wait for someone to post it!

V161 tranny's came out in 1998 JDM market only. not in 93. 93-early 98 the v160 was used. the 161 is the update so hence, late 98 and after.

Also your R154 5th gear ratio is incorrect. It's .753:1

Can someone tell me which 5-speed came with the 1JZ? Was it W58 or R154? I found some sites selling 1JZ's with 5-speed M/T for decent price almost worth it to buy it just for the tranny if it is indeed a R154, but I'm guessing it's W58. Please correct me, as I am merely guessing. This info might help some others out as well, thanks!

I cant recall anyone putting in the 4 speed auto in an IS300 though
Thats because to put a built A340E in an IS300 it would cost you somewhere areound $5000 if not more. At that price you would be an idiot to do that instead of a TH400 or TH350.

-Built A340E + convertor = ~$3000
-Custom Driveshaft ~$500
-IS300 %spd rear end w/LSD ~$500
-PCS Trans Controller ~$800
-Custom mounting/Wiring ~??

This is all the stuff you would need to properly swap a built A340E into an IS300. The Supra Auto's came with a rear end of ~ 3.77, so I guess you could use the IS300 3.91 rear, but the 5spd rear would be closer.

The good thing about buying a 1jz with a 5spd tranny, is that you already get the 1jz bellhousing, all the hardware hopefully and a clutch+flywheel combo. I'd advise getting a new clutch at least, but on the plus side, you get a nice tranny and all you need is the 92 sc300 shifter. ha!

But then again you could go all out and do a 2.5 jz where you using the better flowing 1jz head on the 2j block. That'd be wiked sick...
I was actually thinking about doing something stupid like that, where I'd get the 1jzgte VVTi - use our 2jzge block with a headgasket and the 1jz head - you'd get a single turbo setup, retain vvti, and have an ok boosted setup with the r154 tranny. I think the ass part about it, is not many 1jz parts are available in the US, and I don't know all the specifics of price and fitting...

At that point it's almost cheaper to do the complete aristo motor, but you'd be original. lol.

Is this fact, about the 1jz head flowing better? What makes it flow better, just a better design? What is needed to put a 1jz head on 2jz block, does it bolt right on or is there much modification needed to pair the two? This is something I haven't heard before so I am quite interested, thanks for your input!

Hi
I have been snooping around the internet looking for someone to share some information regarding a problem that I am experiencing with my Lexus IS 300 turbo conversion. The whole build went well with only one major flaw which I battle to solve.
The smooth shifting on the auto transmission. Can someone please share some information on how it is done to get the box to shift like it should
I will appreciate some guidance
