what did you use for your brake booster?

 

looks clean bro...

 

Nice work. Good detail. I learned something interesting from your thread. I've had a minor oil leak on my oil return flange since day 1 and I never thought about it coming from the bolt holes. Always assumed it was from the main return hole. Thanks.

 

Yea I have some more pics of like intercooler piping and other small things. I will post up some videos of it running and some more pics soon.

 

I used the line coming from back of intake manifold. You can also use the line in between manifold and valve cover but I think it looks cleaner the other way. I still have to do some cleaning up of the engine bay a little bit to get it just right. I just got my oil catch can in yesterday so that will help.

 

That turned out really good, yeah definitely take it easy until you get the Street Monster tune, lol. Can't wait for the vid clips. Good job bro!

 

please send me or post pictures of what line you used. To me it looks like you didnt use the one at the top of the intake manifold..

 

I am doing a 2JZ-GTE swap and I went on the www.jdmenginedepot.com the value went up. Is there anyway or cheaper transmission I can get from any website? I can get the engine but the transmission is what Im looking for???

 

Not sure I understand your question entirely. You don't want an engine from the engine importer but just a particular transmission? So you already have a 2JZ-GTE engine at this point but no strong transmission to go with it?

If you are going automatic you want an A341E 4-speed auto from an Aristo 2JZ-GTE or any 90's 1JZ-GTE auto engine set. Or you will want any version of the 1JZ-GTE's R154 that will suit your swap. V160's and V161's are in a very expensive ballpark now.

 

Okay I gotchu. I'm doing a 2 car project right now. The first one is a 1994 lexus sc300 and a 1981 Mercedes 380SLC. I have bought a USA 2JZ-GTE None-vvti shortblock with cams, valve, and everything like the longblock 2JZ, will the JDM Aristo transmission or 1JZ-GTE fit with it? Or will I need to go on another route? Also for the SC300, will i have to modify the driveshaft and differential? Or can i use it? I don't know if you're familiar with the mercedes but I've seen one guy did a 450SLC 2JZ swap but haven't given full intel on his swap. I need to know if the transmission of Aristo or 1JZ 90's will be able to fit on the 1981 Mercedes 380SLC or can direct fit the stock driveshaft and differential of the mercedes.

Lasty, The ECU computer. Can I use JDM Computer on it? or does it need to be USA? Or does it need to be aftermarket like MoTec 600's which ive seen for a lot of people?

Nice cars! Those 380SLC's are timeless!

Yes. The JDM Aristo and 1JZ-GTE A341E automatic transmissions will technically fit any JZ but of course your USA-spec 2JZ-GTE Non-VVT-i will work with the JDM Aristo A341E which is technically the same transmission that the USA Supra MKIV Twin Turbo Automatic came with.

Now if there are minor differences I am not aware of them but the fact is that automatic transmission was designed to be bolted to a 2JZ-GTE (Non-VVT-i and VVT-i).

If you are sticking with the USA-spec 2JZ-GTE wiring harness and ECU setup you will need: whatever model year USA-Spec Supra TT Automatic ECU that you want to use (OBD1 or OBD2) and if your wiring harness is not already set up for an automatic transmission you will need to add a few things before you get it installed on the engine and the car it will be going into.

If you are going with custom wiring and an aftermarket programmable ECU (assuming there is automatic transmission control support) then the transmission control wiring requirements will still be the same.

Your flex plate, torque convertor, flex plate bolts and auto transmission rebuild and strengthening options are all going to be the same as what is available for all Supra MKIV Turbo Automatic transmissions.

You should be able to go this route. As long as the driveline will fit a 2JZ and compatible transmission can be swapped into almost any type of vehicle.

For the SC300 if swapping in a 2JZ-GTE with an Aristo or 1JZ-GTE derived A341E automatic transmission you should be able to re-use your existing SC300 Automatic front and rear driveshafts. There should be no custom driveshaft needed. You will however want to get yourself a 92-97 SC400 rear differential (3.92:1, bolts right in) or a JDM Aristo rear differential (3.769:1 and requires an SC300/400/Soarer companion flange swap to otherwise bolt in). You can also try to find a Supra MKIV TT Automatic rear end (3.769:1) since they often come with Torsen T-1 LSDs reliable up to 500whp (but the seller must show and prove that a Torsen center is included).

For the Mercedes 380SLC you will absolutely need a custom made driveshaft.

I know of, admire and am familiar with the R107 and C107 Mercedes two doors but I've never had any experience with them myself. A couple of W123 sedans and coupes, a W124 sedan and several W461, W461 and W463 G-Wagens through friends who own those yes. I'm familiar in the general sense with how Mercedes did things during that era of their vehicle designs. Mostly my experience is with Mercedes diesel OM617, OM617A and OM606/T powered or swapped models.

I am not aware of this 450SLC with a 2JZ swap but I would guess that a substantial amount of custom work was performed to make it all fit.

Since Mercedes nearly always had long inline-six engines available in most of their vehicles the length of a 2JZ will probably fit. The oil pan clearing the Mercedes crossmember may be the biggest challenge but I do not know honestly. You have two oil pan options with Toyota JZ engines: front sump (Aristo and other Toyota JZ cars) and the Supra MKIV and Soarer Z30's rear sump setup. The oil dipstick lengths are specific to front and rear type JZ oil pans and so are the oil level sensors.

Engine mount brackets would have to be custom made. If possible you will want to use the Mercedes engine mounts when custom making these brackets. The original 2JZ engine brackets are valuable so those you would definitely re-sell.

It's impossible to know how well the Toyota A341E automatic transmission will or won't fit into the Mercedes tunnel but as with many mix and match engine and transmission swaps into vehicles they were never originally designed for you may need to hammer out or otherwise modify the transmission tunnel to allow them to fit.

The automatic transmission shifter unit that goes inside you can probably adapt for the Benz interior or perhaps (I am only speculating here!) you can figure out what electrical signals it needs and perhaps adapt the original Mercedes automatic shifter to work with those signals or maybe adapt a newer Benz automatic console shifter that looks right in that interior. That part is uncharted territory so the only way to know for sure is to start digging into it and experimenting to find a solution that works!

...

As to the driveshaft and differential of the Mercedes 380SLC... again... the Toyota drivetrain was never made for that car originally so you will need a custom driveshaft using the Toyota style end that goes onto the A341E automatic and the rest will need to be compatible with the Mercedes driveline from there on back. And this will need to be balanced properly. I don't know how strong the Mercedes 380SLC driveshaft system and differential are but unless there are stronger/beefier parts you can swap in from the 450SLC of the same production years you will just need to be aware of just how much torque the SLC's driveshaft and rear differential can take reliably with or without upgrades available for them.

This depends entirely on what you want this setup to be by the time you are done. If the engine harness your USDM (USA spec) 2JZ-GTE has come with is USDM then the easiest plug and play solution is a USDM Supra MKIV TT Automatic ECU. If you instead are starting with a JDM 2JZ-GTE engine harness then the easiest plug and play ECU will be from a JDM Supra TT Automatic or JDM Aristo Automatic. There are some minor differences between the wiring of either type of 2JZ-GTE engine harness. And you can modify any 2JZ-GTE engine harness to work with any 2JZ-GTE ECU-- it's just a matter of how much wiring modification will be needed.

You will need to do some custom wiring of the body plug parts of the harness to hook into various functions of the Mercedes body wiring, instrumentation, A/C, etc. anyway.

If you are for instance trying to make this swap California Emissions legal then you will definitely need to stick with a USDM Supra TT Auto ECU of the appropriate year you want to register/smog it as.

If you want to get into an aftermarket ECU that is when you will exceed the stock Toyota ECU's ability to tune beyond a certain power level then sure you'll want to go with an aftermarket ECU setup such as a Motec, ProEFI 128, AEM, Link, Vipec, etc., etc., etc. The important thing with aftermarket tune-able ECUs is how well you or your tuner knows how to work with that ECU system and dial in a very good tune for it.

But if all you want is a 2JZ-GTE that is good to around 500whp max reliable horsepower then you can safely use a stock/OEM 2JZ-GTE ECU (whichever specific type fits your specific build/engine setup). You can even start your build on an OEM 2JZ-GTE ECU of the correct type for your build to make sure the swap has ALL of its bugs worked out to 100% reliable operation and then *later* if/when much more power is desired you can upgrade to an aftermarket programmable ECU of your choice with a custom tune.

The SC300 Automatic will be the easier car to swap to 2JZ-GTE Automatic spec. There will still be plenty of little things to address to get it set up perfectly but all of those things are heavily documented and most are a bolt-in or bolt-on affair.

For the Mercedes 380SLC there will be a lot of custom work involved but even so it is entirely doable so long as everything fits. Also, for the Mercedes try to find a rear end or ratio that is closer to 3.7x-3.9x:1 for optimum gearing. You can run a 2JZ-GTE with a 4.10-4.30:1-ish rear end (I have done this myself briefly) but it is far more beneficial to stay in the former rear end gearing range if you can. For a BIG and very powerful single turbo setup you can go with an even lower rear end ratio than 3.7x:1.

 

thanks u very much your kindness and taken times to promptly answer all my question.....

-for sure sc300 is best easy to swap 2JZGTE.... match all spces.....less modification for sure.......

-the reason y cuz i have 2 cars 380slc & 1 possible get 1991 300sl soon..and thinking swap 2jzgte...and i know will need a lot hrs and times to modfication more sc300..i will check all gear ratio and look re-search modification rear drive shaft....

-i am also saw some guy swap 2jzgte sc430 2002 that also i am thinking try to do that as well......but like u said show full explanation nothing is easy need a lot hrs times effort to make it work..

-i will look into another sc300 see if i can find any local here...... i saw u have sc300 with R154 manual trans 5 speed that is nice looking car........maybe i go that round is taht first time to own one cheap and easy simple car to swap 2jzgte with or without automatic A341E Aristo or 1JZ-GTE trans....

again thanks u very much your times and effort help me answer all this detail about 2JZGTE swap.....
