I have done some searching. First I am getting a 95 GS300 with 200k miles. I am a Lexus tech and I have a motor from a 02 is300 that need to be rebuilt. Im wondering ifitis beneficial to use this motor for a turbo build? Or jus go and get a jdm 2jz lke alot of threads I ave read? Also i am aware th the newer IS motor s DI ( dstributoless) whichis why I wonder if itsworth it. Im not looking fo answers...maybe some posts i ca read through or w/e.Thanks.

 

The engin off the IS300 is a VVTi block which is has weaker rods and not sutible for a turbo build. Better off finding ur self a JDM engine

 

not to metion wiring would be a pain in the A$$ going from non vvti to a vvti motor....and Yes the block is weaker.

 

OK so im narrowng down my search field now. My best optionwould be to source a jdm 2jz-ge or gte. Also found someone here swapped a ijz-gte. ay specific year?



Found this on ebay. IS this the right or acceptable year that you allare recomendin?

You mean a 1JZ not a ijz right? That link is to a VVTi. You do not want vvti in a 95. A 2JZ-GTE from a JZS147 non-vvti will be fine and will just plug right into the car with no mods to the harness besides lengthening it.

 

Ok so im clear on the jzs147 swap. I printed out the entire thread lol. SO does anyone know or have an opinon on just doing the bottom end. I dont plan to go crazy with boost or hp..thinking a max of 400 which from what ive read is about the limits of the stock jdm 2jz gte ecu. The motor ( my stock GE) has 200k but has been maintained in lexus all its life until 193k. I just want to see which route is cost effective. If im goiing to spend 2500 on a swap verses less by peice build a turbo and doing bottom end work. Thanks all...

 

By the time you piece together a proper turbo system and get it tuned it will cost about the same as the swap, except the swap trans is far superior. Do it the right way.

 

Ideal Swap options:
-JDM Aristo motorset + V160 tranny (MKIV Supra) if you plan on going above 350 whp and want a manual tranny (the swap we all dream of)
-JDM Aristo motorset + R154 tranny (many n/a toyota cars) if you plan on keeping it below the 350 whp mark
-Just want an auto/turbo car? JDM Aristo motorset
-Dare to be a tad different and compromise a bit on the torque for a revvier engine? A swap from a the X90 and X100 chassis (Chaser, Mark II, Cresta, etc) should do. The engine would be: for the X90 1jz + r154 tranny; for the x100 1jz with VVTi + r154

A swap and option I really don't care about and it is worthless IMHO?
A x90/100 1jz swap but auto tranny and a 'turboed' 2JZGE. Just get the Aristo motorset. Way worth it.

These are just my opinions but I do think everyone agrees.

 

Thanks alot. Im doin all of the leg work but I have decided to do the Aristo motorset. I want turbo but not looking for another manual. Thanks all for yoiur input.

 

awesome. keep us posted on your project and welcome to CL!

 

Thanks...im startig to shop around for none maintance items like turbo timer, BOV,etc...anyone have a list of must haves? I was looking into boost controller...will this work on the TT setup?

 

No Toyota N/A cars have an R154. They use a W58, which is good to about 400whp if you don't abuse it.

R154's are good to 800whp or so, depending on the condition. They're getting harder and harder to find these days.

To swap an R154 into a 147, you need to get an R154 with an extended shifter housing (very rare). if you can find one of these, they sell anywhere from 1000-2000. If you use a top mount R154, you can buy the custom extended shifter housing from driftmotion.

How do i know?.... I have a R154 JZS147

 

if u can use a v160 in a sc300 and it fits perfectly than a soarer r154 with the extended shifter housing should theoretically work i would think it would be a lil shorter and make it closer to the ashtray tho but still perfectly liveable

 

About the W58; I stand corrected, thats true and I forgot about it. The R154 is from the mostly 1J turbo applications. Now, about the power thay can withstand, I think this is where it gets grey and mixed opinions come up. I have heard many many things about these trans breaking at about 350+ whp from 1JZ and 2jz owners (chasers, cressidas, MKII's and N/A turbo converted supras) and other people say they drive their 600hp DD just fine. I think it does depend on the abuse you give it.

Hmm... measuring my buddies X90 MKII seems the shifter is fine and long enough to fit in the hole on my GS without mods... maybe it has an extended shifter housing? I do think Soarers and MKIII Supras don't have the extension since the car is shorter than a X chassis but I might be wrong... I'll confirm this once I get the x90 front clip.

 

Yeah it's mixed reviews because some guys don't know how to treat R154's. They're not a W58 or a V160 where you can plow through gears and wot shift. They're a slow shifting tranny. Again it depends on the condition you get them in, I've seen some break at 500whp, and we have some running 800whp on stock internals.

90% of broken R154's I've seen are all because of the 1st-2nd shift fork being bent or broken from abuse.

I'd recommend the Marlin Crawler rebuild package for the R154 to everyone though. They build a great tranny and they take lots of abuse.

Top mount doesn't work, it's too far forward. I believe the X90 comes with a remote mount, but i'm not 100% sure.
