98 supra NA->TT

[spot]

I have a 98 non-turbo supra with the vvt-i engine. I am thinking about doing a 2jz-gte engine swap. I don't know a lot about engine swaps. What all do I need to do. Can I just buy that engine swap it with mine and I'm good to go? Does all the transmission requirements come with the engine or do I need to buy a seperate tranny? Anything else I am missing? How much would all of this cost? Also how much could I sell my vvt-i engine for if I did this?

Your help would be appreciated thanks.

i did a swap to my 93 supra we got a jdm 2jzgte with a 6 speed trans and it was not cheep motor trans and ecu were 5k then i had to buy a rear diff,drive shaft,wire harness,tach,a usdm ecu,the hole exhust system,o2 sensor simulator and a bunch of other little stuff and it wasnt that cheap but that is all up to you i know you can by the motor without the trans so i was told but the most expensive thing to due was the 6 speed trans convertion.

[spot]

o so how much was all that? and how much do you think i can sell my vvt-i for?

[jrodd]

im not sure how much you can sell your motor for but i would check on ebay to see how much other people sell them for.like i said before,the most expensive swap was the 6 speed i spent 5k on the motor and trans,the wire harness was 1500,the mass air flow sensor was 250 used,the usdm computer was 300 used,the drive shaft was 950,the rear diff was 2k,intercooler and piping were about 1k,the exhuast was a tanabe and that was 750,the down pipe was 90,and the tach was 250.i also have a turbo timer and other small stuff like coolant hoses to throttle cables.

and how much do you think i can sell my vvt-i for?
Unfortunately, probably not a whole lot, like $500 to MAYBE somewhere near $1000 (with trans, ecu, uncut wiring harness). Think about it, most people looking to by a motor are looking ot upgrade from what they have now, which is often the 2JZ-GE (non-turbo motor).

[Quicksilver .-MKIV-.]

for that amount i rather keep my motor (it has 16k miles) then build the motor later on when i have lots of $

jrodd- your 93 was an AUTO before the conversion right?

im gonna go JDM TT auto (about 2.5k - 3K full engine/trans, ecu, harness) but will keep jdm twins, converting camshafts, harness, ecu to USDM, and adding on MAF

other parts ill be adding are BCC, Blitz BC, Boost logic FMIC, 4" dp, larger injectors(hadnt decided yet), boost gauge, TRD tach or TT whatever comes first hopefully TRD,

[Lexurious COupe]

TRD tach or TT whatever comes first hopefully TRD,
There was a 10k TRD tach on E-bay recently, but I think that bid was up to like $400 or something.

wat is a jdm motor. i keep hearing jdm.

[jrodd]

quicksilver-my 93 was a 5 speed but i can just picture how much more it is to go from auto to manual
also the tack has to be replaced the na tach gets a differant signal than the turbo tach and me personaly i would not spend that kind of money on a trd tach. it doesnt make the car go any faster

[jrodd]

spot-jdm stand for japan domestic market jdm motors are usualy imported from japan and usualy have beter mods than we do like the 2jzgte has bigger turbos than the usdm also usdm stand for united states domestic market which motor are you looking to get

[Quicksilver .-MKIV-.]

to easily perform a swap just go for a JDM engine, and convert it to USDM. plus they have LOW mileage! usually around 30-40k miles only. be sure you get the Supra motor not the aristo, if you get the aristo then you will have to also swap the oil pan and water pump to supra oil pan/water pump which is wasting more money.

i think you are 98 NA auto correct?? just like me.

i recommend you going for the swap that im doing, unless you want to also convert to stick (Which is 3k more, not including tranny) 5k for a jdm gte-6speed plus 3k more for misc/accessories parts for the tranny. the only differences the JDM GTE have are:

Camshafts, Injectors, turbos/manifold, ecu/harness, MAP sensor instead of MAF sensor, and EGR (If you must add it)

face it USDM gtes are hard to find, if you do the motor itself will easily cost 3k just like that (unless you get lucky :)) and usually they'll have 80-90k miles or so

well wat do u guys recommend? Where would i even get a jdm motor. can i do the regular bpu mods to the jdm? quicksilver when do u plan on doing this?

[jrodd]

spot its up to you and your pocket to me it was well worth it to some people they think ts better to buy the tt version and thats it to me having the car a building it the way i want it makes me enjoy it more you can just do the motor swap or motor and trans

[spot]

o so the jdm motor isnt twin turbo?

[jrodd]

spot-it all depends on the motor you want you can the twin turbo with an auto trans or manual trans 5 speed or 6 speed i bought mine from osakajdmmotors.com but i rec not buing from them

[Quicksilver .-MKIV-.]

it is twin turbo but the material used is ceramic and they are smaller, they're 280HP they spool faster. the USDM turbos are made of steel and they are bigger then JDM turbos, they produce 320HP.

[spot]

o0o0 i see well i will have to look into it. hopefully ill have it done for christmas and bpu it. Put a paint job on it and man i will be in heaven.

[Quicksilver .-MKIV-.]

ill get my shot next year.. *glup* hopefully :( but i'll know what to do already :D

[spot]

Does anyone want to tell me EVERYTHING i need to do to swap my vvt-i to a 2jz-gte in my 98 supra? I need engine, transmission...what else like ecu and other electrical things? If someone could just write out a list for me that would be great. (please don't leave anything out)

[Lexurious COupe]

Engine, Trans, ECU, UNCUT wiring harness <-all that should come with a "clip", so it shouldn't be a hassle to source parts.

You may or may not need some sort of intercooler; lots of engines and/or clips are sold with them, lots without. If you don't get one with the engine, you might as well go ahead and do a FMIC instead of the stock side-mount, unless you really don't have or don't want to spend the extra cash. You'll also need a fuel pump, either the stock TT one or the Walbro (which is like $100 for the pump and install kit).

That's all I can think of that you will absolutely need, but there is endless room for upgrades.

Also, since you have your engine out, and the new one hasn't been put in yet, it's a good idea to just do some basic maintainence stuff; new water pump, idler pulley, timiing and accessories belts, plugs and wires, and if you want even a new clutch if you're a stick (all up to you though). Personally, when I changed engines (swapped a GE for another GE... don't ask), I also put in new motor and trans. mounts. It might make life a little easier down the road.

Did I miss anything?

First I got to ask you if you're going for the route I recommended... which is a JDM 2JZ... most of these engines are sold in sets (Engine/tranny, harness, ECU) I assume you're going to stay auto so the JDM engine set will cost around 2.5k-3k.. Now do you want to convert it to USDM or keep it JDM? If you want to convert it to USDM you will need to swap out the injectors, camshafts, turbos/manifold, add a MAF sensor, harness/ecu to usdm, and switch your NA rpm tach to TT. If you want to save money get a stock sidemount intercooler. And there you have it a full JDM 2JZ-GTE fully converted to USDM. Yea also swap out the fuel pump to a TT or walbro, walbro is cheaper I think.

I cant believe i missed this post lol!

I dunno if they are selling just the motor..you may wanna google out some motor companys, also try ebay. hey arent you from vegas???? West coast gets a crap load of connections..you should call up some shops and ask them if they can get you a motor.

Actually the site i posted probably does sell the motor and tranny together, thats all you really need because the jdm harness/jdm ecu are useless if you want to convert to USDM that is, you should give them a call

[spot]

i think im just going to get a usdm 2jz-gte. A shop near me has it in stock with about 70,000 miles on it and I'll problably do that. thanks for the help guys.

[Quicksilver .-MKIV-.]

Congrats. how much is it though, does it come with a tranny,ecu/harness?

[spot]

I'm not sure of that yet quicksilver.

So all of that takes care of the engine but are there any other things i should change on my NA that the stock TT MKIV's have on them like brakes. Do they have like different steering components or any miscelaneous things like that. I just want to truly make a whole TT car not just the engine.

[Lexurious COupe]

Well, why didn't you try to find yourself a MKIV TT? Yes, the TT brakes are different... and also like a $3,000 upgrade for front and rears, PLUS you'll need rims with Supra offset or more to clear the calipers. I mean, everything is different; interior, frame, body, etc - It's a different car.

meh...worry about the brakes later...i know plenty of people that are either NA>TT or NA>NA-T that still have NA brakes on, and they don't have a problem.

unless you're loaded with cash then do whatever you want

[spot]

haha not loaded jus dont wanna fuck shit up. thanks for all the help guys. if not for christmas then definently by july!

[spot]

Hey I think I want an auto tranny and the engine has a manual tranny on it. My tranny now sucks and wont handle the hp. Do you think I should get a boost logic built tranny?

[Lexurious COupe]

Sure, but if you're gonna leave the engine semi-stock for now, then finding one with and auto would be a LOT cheaper... unless you're shooting for like 600whp, then go with the BL built one.

[spot]

ya only problem is finding the auto engine. ill keep lookin

[Lexurious COupe]

Touche... wait, are you trying to find a USDM engine? I think maybe I missed something...

[spot]

ya

[Quicksilver .-MKIV-.]

just dont build the NA auto to the boost logic built auto, just giving you a heads up, because i've seen more than enough people use an NA tranny core and they all have had slipping issues.


however if you use a TT core then you're okay.


have you found that usdm yet? :)

Interesting... what's the difference once you have them built? I don't know very much about tranny internals and such, so it may very well be beyond my comprehension.

[spot]

no haven't found one. if anyone knows of a usdm auto tt holler at me.

[trafik]

Well let me first introduce myself,
Matt
Chicago
93 NA

I will be swaping to 2jzgte by the end of march and I need some pointers from you guys. First of all dose anyone know anyplace that sells USDM engines
( yeah I know hahaha, another newbie). Probobly not and the JDM ones are cheaper and have lower miles and better condition ( not allways true) anyway so I should just deal with that ,right? If I am going to pull the US NA auto and drop in the JDM TT auto still have to change all of the stuff to USDM like the injectors, camshafts, turbos/manifold, add a MAF sensor, harness/ecu and switch NA rpm tach to TT???? Is that all the stuff I have to do just to make it work? Can I keep the auto ecu or no? Will going single right away help in the swap when I will be droping it in? I dont get the whole deal with the egr.

To make my long boring question short, I just want to know how much crap I have to do just to make the JDM work in my 93

thanks you guys are great/

[USMCSupra]

Honestly, guys, you're not going to be finding a 2JZ-GTE USDM. The only way someone is going to sell their USDM 2JZ-GTE is if they totalled their car. If you guys are on a budget, and don't mind a lot of custom work, sticking to JDM might work for you. If you can, convert to USDM as it will give you a better platform to put mods on later.

Spot: If you have a 98, make sure you pick up a passenger side engine mount bracket for an OBDI Supra if you end up picking up an OBDI JDM motor, they're different. If you go 6spd, you will need both rear axles as they're different on the 98's. Your tranny is much stronger than the typical NA Auto tranny, but I would get a built auto if you have the money. You might want to start looking towards a JDM motor and converting it to US Spec. If you don't want to go through the process or have trouble finding what you want, go on supraforums and PM Sherbaz. He is very reputable and will take care of anything you need.

Use a US Ecu/Harness for a us spec vehicle. If you're keeping everything JDM, you can keep your jdm harness/ecu... but you will have to extend the wires into the harness... pita. If you have the money, do it all in one shot, it will save you the trouble of taking off the stock twins later on.

[trafik]

Well I found a USDM engine and tranny with a uncut harness and ecu, it has about 45 K on it a and the comp. is good. $4500..

P.S what a good setup if you are going single ( turbo , manifold ,downpipe ) or just a good setup.
