6G Celicas Forums

I have also been watching all the traffic on MR2oc. what i want to know is what 2GR is the best to use? RAV4? all the talk about immobilizers gets me concerned. also what about he wiring? what is involved for body harness?

The thing that we need to contend with is the lack of vertical clearance in the celica engine bay. If the MZ barely clears the hood, what's to say that the taller GR will fit? can someone get some measurements of the motors for some benchmarking?

I'm itching to do this swap hardcore, but there is still a lot that needs to be addressed before I can take on a project like this. As my 6g is my DD, I can't do the necessary research required to answer my own questions, let alone the ones in this thread.

ask and you shall recive!!!

only mods done are the ones nessisary to do the swap.. IE: full exahust, and intake.. oh and eliminating the slush-box
this is one of toyot's best flowing motors in the head/intake manifold, toyota sqeezed the hell out of its ability to breath with a sevierly restrictive exhaust. that coupled with a very heavy slushbox = the rated HP that this motor gets when in "true" stock form...
again, this is ONLY with "mods" that it takes to do the swap.. NOTHING els..

oh and gouky's VERY in-depth thread
2grfe swap thread

oops. did not see that FORGMANN had already posted the sheet..

I have wired for about a dozen of these in mr2's. All of my harnesses have been based off of the 2plug harnesses for use with the nonimmobilized rav4 ecu. The 2plug camry engine harnesses are ok to use with the rav4 ecu. For the basic motor, you can use just about any 2gr you can get your hands on.

^^^ thanks for the response, now how much different will the wiring be in a 6th gen. there are big differences between ODB1 SW20s and ODB2 celicas. plus CA smog BS! i couldnt have any CEL on. i know that in toyotas the 2GR is only mated to an auto, but what about the lotus evora? its a 6 speed manual. so thats my loophole for mounting it to a manual tranny

The automatic tranny codes kill the rav4 ecu for California. That and the stock 2gr exhaust manifold interferes with the clutch slave cylinder, so you're stuck with headers, another problem for CA.

You could potentially use evora exhaust parts and the evora ecu, only problem is that those ecu's are all immobilized.

This is definitely an area where toyota is inferior. I've done a number of swaps with Chevys. The ecu's are open, so all I have to do is plug my laptop with tuning software into the obd2 ports, access the ecu, and uncheck the box for security (and rear o2's and evap and automatic). With Toyota, you would think you were trying to access some military secret. The dealer can't even disable security.

i know that connor just got cal/smog leagal.. im not sure that it was a 2grfe though..

Edit: its a 1mzfe.. never mind....


Smaay do you not have family in florida or alabama, or any of the other very relaxed emissions states that could "own" the car for you?

Let's keep the discussion alive guys. I want to see this happen. Why is not someone on top of this....

i work on 2gr-fe all the time at work and 1gr-fe on tacomas and a bunch of other motors, the 2gr is very powerful and torquey, reliable of course, doesnt sound great stock on camrys etc, lol but yeah its reliable i havent had issues with it, and only thing i see normal mait water pumps leak here and there but thats prev, maint. great idea for that motor but its big, and where would u just find a motor? its fairly new on newwer cars

the problem with this swap, is no one is done it or tried on a celica. The motors are plenty on ebay, and yards now. people wreck cars every day. its a matter of grabbing the balls to do it. but no one seems interested here. I guess its the cost.

u should lol

The cost is prohibitive, but I think about the 2gr every day.
No one knows for certain if a 1gr crank will fit in a 2gr, there you would have the potential for 4 liters fwd.

Also, my favorite part about this swap is that the S in ST204/ST202/ST205 stands for S-series engine and the AT-200 has an A-series block so a 2gr equipped celica would be a GRT-204 or GRT-205

Just a matter of wiring and the cost associated with that. Will it be worthwhile going through the hassle versus just dropping in a 1MZ/3MZ hybrid? Though haven't those with MR2's done this now? So one should more or less be able to take what they've done and apply it to the Celica.

Why don't you do it?

If I had the money

290 HP, N/a on a celica, its worthwhile, and the swap is a couple pounds lighter than the 3sgte...

i have too much on my plate, atm. beleive me if i did not have a tore car in my garage, i would totally do it...

the 2GR is a kick ass engine, when the cost of them gets down to 700 like a 3MZ then ill attempt one. until then, ill keep my 240 torque 3MZ

Blade Masters have the 2GR's here.

There was a NZ'er with a 2GR SW20 MR2, in the end making 208.7rwKW, since sold.
