hello

searching for info on some new generation toyota engine swap possibilities. specifically i'm thinking about motors from this generation tacomas (both the 4 cyl and the V6) as well as the 2GR-FE (out of the RAV4). other than winddancer's thread on his 4.0 L 1GR-FE V6 swap i've not found much. it doesn't seem very feasible for my needs anyway so i'm starting to think about other possibilities.

the 2GR-FE has really interesting numbers and doesn't seem to be too big (or heavy) but i don't know what it would take to mate it to an R150F

i'd also be interested in the 2.7 L 2TR-FE out of this generation tacomas. it makes the same power as my 3.slow but probably weights much less (haven't located the exact weight yet) giving a much better power/weight ratio

anyhow, it would be great to start compiling info on other options

If you were ok with putting in an auto Id say go with the 1uz instead.Not very much info on the other swaps you are talking about.

Just recently finished mine and what a difference.

 

yeah, i've seen the 1UZ info (including your thread, thank you for that btw, wish more people took the time to document swaps like you did) but i'm strictly opposed to autos.

I'd drive a Rav4 before considering it. Those engines don't seem to make much low rpm power unfortunately, and thats on a lighter vehicle.

 

what ya tryin to swap these into? 4runner or truck?

 

lighter vehicle yes but engine hp/torque is what it is. i don't know about the torque curve on those motors, something else to look into

edit: after a quick search i found this: http://www.toymods.net/forums/showthread.php?t=43884

2GR-FE into an MR2. his dyno shows some nice power.

into my '92 extra cab - don't need swap right now, just want to figure out what i'm saving towards

 

i hear you on the RAV4 motor and you are probably right (though that dyno does show some power down low) but i'm not willing to rule it out yet because it is a great motor, plenty of power and great fuel consumption - i'd consider the 2GR-FE for the same reason: it's the same power as my 3VZE but with less weight and much better fuel consumption. i'm trying to find a balance between power and MPGs

The 2gr is a front wheel drive engine. Not sure how that would affect a rwd swap.

Does anyone know what trannys will bolt up to any of these engines?

 

why not the 3rz the 2.7 4 banger from the taco's ? pretty much the same thing as the 3.0 performance wise better gas mileage and pretty much bolt up in a 22re equiped truck.

 

well, i've done that swap already (2RZ into my old '85). i liked it but had to sell the truck because i was moving abroad.

the 2RT-FE is interesting because it appears (i say appears because i don't have the key piece of data yet) to be much lighter than the 2RZ or the 3RZ. it is all aluminum and has a ton of plastics incorporated to save weight (and cost of course). it also has VVT-i which is better at managing power and fuel consumption than previous generation motors.

check out the chatter on marlin: http://board.marlincrawler.com/index.php?topic=48380.30

this would appear to be the swap of the future for those of us hunting for manageable power without a ton of weight.

just remember the 2rt is drive by wire, so u will need all of the wiring with the electronic gas pedal too. it sounds like a pain to mee, but i would like to see someone swap one of these into an older truck

 

i know, drive by wire sounds like a total PIA but i am looking for a project to learn more about electronic components. still, i'm a ways from taking this on, just playing with the possibilities at the moment.

i would have to a) verify the weight differential and b) find a way to bolt it up to my r150F trans before i considered doing it.

the 2rt uses an r series transmission stock, so it will bolt right up

 

reviving another dormant thread: any data on weights? found an old post that puts the 3VZE at 350lbs but no other data to verify. there may not be a lot of power difference between the the 3RZ-FE and the 2TR-FE but the weight difference plus the VVTi would definitely be something to factor in. then again there's the drive by wire...

 

I truly think that the 2TR-FE is the swap to look into or attempt. It bolts to an R series transmission with it's bellhousing so it seems to me the big deal is the electronics. Also, as a note on power, it actually makes more power than a 3VZ-E by a whopping 10 horsepower. It is a tad weaker than the 3VZ-FE numbers wise, but seriously, which one would win the race?

All in all, I think this swap is one that will be doable for the v6 trucks and guys that want better fuel economy and the same horsepower, though it will end up being faster as well I'm sure. If it's documented, I'd love to read up on that swap. It just sounds awesome.

 

The weight and vvti is something to factor in, then factor out how it will be accomplished. I read a bit on K20a.org when I had a K24 civic and your looking at a lot of work for a bit better engine. At least in the civic you gain 100hp and go from 90 hp to 205hp. Plus many import guys are not concerned with being street/smog legal.

Things I can think of to consider when trying to get a DBW engine in a DBC vehicle is the throttle body, ecu, fuel management (return vs returnless), possible stand alone engine management system, gas/clutch pedal from donor car...

My vote is the 3RZ
