So guys since I'm new here what type of 0-60 performance are you getting out of your gs300's. I'm talking about after mods not stock.

 

According to my HKS Type-1 Turbo Timer, I can do 0-100km/hr (0-62mph) in 4.7 secs. I am running a HKS megaflow filter, GReddy Front Mount Intercooler, HKS Twin Power Ignition, Unothordox Racing SS Underdrive Pulley Set, HKS EVC-Pro (boost set to 1.3 bar (18psi), Sard Exhaust and other goodies. I expect to get lower acceleration time with the TRD LSD sitting in my bedroom floor. This is my major mod:

 

how ,uch did the engine cost you?

 

biggie27: Too much. The custom work, additional parts and WAIT/LAG for more parts is what is empting my pockets. But if you are interested in the conversion, be expected to pay $14,000-15,000 for a fully converted Aristo minus the E-Shift option (since my car is was a GS300).

1SICKLEX: Bro I don't know if my car can be classified as a Lexus anymore. That and I my car is basically a guinea pig. But as for performance... I am waiting on a piggyback/stand alone computer to utilize a single turbo setup and larger injectors like Steve's Supra. Uhh yeah.

 

why minus E-shift? If the engine is a conversion, with the ECU only able to understand the 4-speed auto, hence bringing along with the engine the 4 speed gearbox, then shouldn't you get the same E-shift from Japan? Or you just don't have the steering wheel?

And yours is single turbo? thought it's complete transplant.

 

If you (like me) with 2001 and earlier GS300s you don't have the luxury of a standard E-Shift. The main transplant components are engine, 4-speed transmission, ECU, and wiring harness, hence the e-shift option is not available. If you can obtain the V300 gearbox then you are one lucky SOB. I couldn't get a hold of one nor can I get a hold of the Aristo instrumentation cluster. I can gate-shift (I'd rather not though) with the GS300's 1-2-3-4 standard gearbox.

I want to use my single turbo without the harsh idle. Believe me, I really do. 440cc injectors and a T04-based turbo not really a good idea. The Supra 550 is barely enough. Therefore, I am running the stock ceramic twins. I have a spare set if anyone is interested for custom work. I have tried the 550cc injectors but tuning was a bitch because I don't have a baseline example/program to follow. I could use the HKS Super AFR but that will help an extent because I want to get rid of the air sensor. I can use the VPC and the correct rom chip for bigger injectors and remove the air sensor, but I'd rather get the F-Con S whenever it is released. Sometimes this month hopefully according to a respected authority. Heck I even have the F-Con harness ready. Once I have the missing link and negotiate with an unnamed FCon tuning facility, the missing link is found and my "Battle GS Cruiser" is ready.

 

Oh yeah. Our standard GS300 gearbox is 1-2-3-4-D. It basically has a 4-speed auto sequence and D as default setting.

 

I'm still somewhat confused. I thought the 2JZ-GTE V300 gets the 4 speed auto with the E-shift. And the 2JZ-GE S300 gets 5 speed auto like all US GS300s. If you're doing a transplant with the V300 engine, then shouldn't you have the 4 speed auto with E-Shift?

You said because yours is a 2001- GS300, there's not standard E-shift, ok, but since you did a transplant with a new transmission, then.............. isn't it the 4speed with E-shift for V300 in Japan?

 

GlobeCLK,

I am not a mechanic but I can give an overview of what is on my cay and what I have been taught. It is really not that complicated. E-shift is not something built on the transmission itself if that is what you are implying. Just think of the 4-speed transmission, the E-shift/steering wheel, the gearbox, and the ECU as separate entities. The Aristo V300 ECU acknowledges that the transmission is 4-speed with overdrive. It will not detect an irregularity in the gearbox simply because there is no E-shift and in its place a "4." Let's now move to our 98-01 GS300 gearbox. It has the commands for P-R-N-D-4-3-2-1 and not for a 5. I can attach the Turbo Supra/Aristo/Chaser/Soarer/MarkII 4-speed transmission onto our 98-01 GS300 gearbox. They will junction and conform to the P-R-N-D-4-3-2-1 where D is the default automatic gearing and the numbers indicate the appropriate gearing. If you set the gear on 4, you will be running on the 4th gear and not the "M" or E-shift. You do not need the Aristo gearbox to run the 4-speed automatic tranny. However, you do need the correct Nipon Denso Toyota gearbox with correct connecters to communicate with each other. And luckily, they right plug in. E-Shift is something programed on the ECU and would be online if you bring it via "the M" slot on the V300/GS400 gearbox. I don't have the luxury of the M button or the steering wheel, therefore it will never be online.

In theory you can attach the 4-speed tranny onto the 2JZ-GE (I do not advise it). The ECU is still programmed for a five speed. Your shifts will be hard and everytime the automatic/D shift kicks in your RPM level will drop tremendously and unless you floor it you will be back at the gear before (loss of power). I am not even going to guess what would happen when the computer tells the transmission to go from 4-5... probably not going to happen because there isn't a gear 5. I hope I answered your question.

 

yah u did. thanks for the detailed info man. Hope to see ur GS monster soon!
