Dude i really don't care i will post the pics when i get to them,I am not hurt ,anybody can say what they wanna say because i started this threard and i didn't post the pics.If you don't wanna hear about the progress without the pics then don't look at my thread thanks.
:confused: I think you must have missed the good natured humor in my post ...

The "hit us where it hurts" comment was just because no legend owner can bolt up a turbo and aim for 500 HP that easily, the comment was all in good fun.

It's really easy to work on them a lot easier than the Legend.I am going to stop the project and pull my car out of the garage cause one of my friend the GS300 totalled his GS so i am helping him parting it out.The Turbo oil return line got melted and everything caught on fire the Turbo and Battery sit side by side so basically evrything that has plastic under the hood is toasted .So his giving me a lot of parts for my GS and the SC
wheels,Steering wheels,Woodgrain,Suspension a lot of parts.So my project will start back on monday.
I got everything only thing i waiting on is the heads Studs and the machine shop i am hoping they will be done the heads and block tomorrow, then i going to pull the motor and trans out.

I will take the pics of the Performance parts i am just kind of stuck right now.

Thanks man

So i got the engine back from the shop , trying to replace front seal and the cranshaft sprocket would not come off,second the the original engine doesnt have a CPS that mean the oil pump is different but i can still use it no problem.
Now i need to lower the compression to somewhere between 8.5.1 to 9.1.1 ,then i did some research on SF to find out what headgasket to use some say 1.3mm,1.6mm,2.0mm,2.5mm and 3mm which is to much .
the 3mm is to tick and it will be fun puting the T belt on and the ARP studs.
the 2mm and 2.5mm are about 360$ which i dont need cause i am not trying to run 18lbs.
So i decided to get the GTE headgasket which is 1.3 or 1.4mm but nobody seems to know the right tickness!!!
I ordered the gasket and they brought me the wrong one ,so i reorder it this afternoon let see what happen now!!!!
As for the parts i am thinking about selling it to my buddy and buy the BL 2.5 kit which is more money, but i wanna do it right the first time.
The Turbo needs a rebuild that will cost me 1400$ per Precisoin when i call them ,because it's a DBB nobody sells a rebuilt kit for it except Garrett and Precision !
that a price of a brand new Turbo ,i can get a GT35 for 900$ shipped brand new.
That's why i am thinking about buying the whole kit and be done with it.
I will keep you guy posted

I so wish I could dive into projects like that.

Looks like your working hard, fastest progress I've seen documented here.
Ok thanks i have a lot of work to do man!!! still haven't pull the engine out yet!!!!
I got a Race built tranny A650E Valve body Upgrade,sprags and Lextreme TC 2800 Stall but i will just keep that for my GS and do the manual swap on the SC ,500+ whp will be fun to drive in manual trans.
I have so many parts in my garage so no room to put the old engine and trans, that's why i still haven't pull them out.
here are the gaskets

Yeah the GT35 is the deal of the year for 900$.
On your GS it will be A340E which is 4 speed O/D maybe about 2000$
And it all depends on what you wanna do with my GS i will do the the 2JZGTE VVTi swap cause my car already has the VVTi and i dont wanna loose it, with the GTE non VVTi i will have to relocate the motor mount brackets,which i dont wanna do i just wanna plug and play.
If you are not looking for more than 400whp you don't need a race built trans ,again if you don't let it slam in gears or don't beat on it just get a bigger tranny cooler and a 2800 stall TC and replace your rear end you good to go.
I have been lazy for a few days i am going under the car tonight ,i got the head of sunday night , i will try to pull the engine and tranny tonight maybe tomorrow ,This project has been moving slow this week and i have a lot cash tight up on some parts that i am not even using !!!! for the swap
I will have some update tomorrow :yes:

lol now i know how people feel when i post a bunch of Honda engine/trans codes. Im not familiar with Lexus and all the engine codes are confusing as hell. I like learning them tho, so keep it coming!

ok with lexus the 98/05 gs300 the trans are A650E which is a 5speed auto and 4 speed auto with O/D from 93/95 not sure about 96 and 97.
same thing with the sc300.
I am not sure about the the 400s, i guess cause i don't have one!!!
The manual trans in the sc300 w58 can't handle more than 500wrhp
The r154 mkIII supra Turbo from eighty's to 93 800rwhp
The w58 is in the non turbo Supra MKIII and MKIV
The V160 is the Big boy up to 1400 rwhp,from the 93.5 supra till 97 TT.
the V161 which i sthe same as the v160 for the 98 supra TT.
With my sc 300 i am going with the w58 i got a good deal on it ,let see what happen otherwise i will upgrade to the r154.
The Us R154 and JDM R154 are different!!!!!!!!!!!!!
the the US R154 u need to the 1JZ bell housing which is found in the JDM SC300 ,Chaser and extend the Shifter about an Inch to work in the SC300 or 400.
The JDM R154 will work the SC plug an play, same as the V160 and V161.
The V160 go from $5k to $7k brand new and will be the last tranny you will ever need.

Thats watsup. Can't wait!

BTW the funniest thing happened this weekend. Being foolish I caused a connecting rod bearing to spin which probably caused a flatspot in the crank.

Now I gotta replace the motor and I am debating on changing from a 2jz to a *UZFE V8 with trans(if it's as easy as getting an SC400 wire harness, custom motor mounts and custom exhaust, only because of the torque) or 2jz GTE. But most likely I'll just drop in another 2JZ-GE because I need the car to be driveable asap and still remain on a strict budget. Especially since I plan to take the car down this winter to build my version of an Aristo.

Any advice or words of wisdom?
My fault for the threadjack.

yeah i can be done some Aristo came with V8 in Japan i am talking bout 91/96 aristo which never came to the US till 98.
I have a few block in my garage right i am trying to give away, i dont even have room to work on my car right now.
I gonna be a pain to get the V8 in there and a lot of wiring i can get u the v8 motor with trans ,ecu and harness let me know.
