Randomly came across this...

I'm not going to argue semantics but even if you did build your own T Sport you're still gaining close to 200 lbs and if I'm going to go through the hassle of a motor swap which I'm forced to gain weight Id rather do it for more than a 22 hp bump is all I'm saying.

And yes I don't like the look of the XD either.

how are you gaining 200lbs? the engine weighs about 40lbs more than a 1nzfe

you gain as much weight as you do adding a blitz supercharger kit...i weighed mine when i had it.

intake/header/exhaust ive been seeing about 145whp/140wtq on corolla's...thats on 87 octane and on an oem ecu

i ran 135whp/130wtq with i/h/e and 91 octance on my yaris...

im not saying that an engine swap would be easy...it won't be. but oem reliable power is a plus in my books

[xnamerxx]

I was using the T sport as reference which weighs about 180lbs more than the standard car.

What corollas are you seeing that make 145 hp on 87 octane? I don't think I've seen a single corolla not powered by a 2zz make anywhere near that much power N/A but excluding that its still only 20 hp more and your adding weight in the worse possible place in front of the axle. I'm not saying a superchargers better but its substantially cheaper. Hell my competitor with a 1zz corolla didn't even break 125 and he built it to the limit of the rules.

If you take into account the cost of getting the ECU, Transmission, Engine, Axles, and accessories pus the time it takes to swap it it just doesn't feel like its worth it for such small gains.

If your dead set on swapping a motor getting the 2zz swapped would be a much better choice as the gains make sense plus the motor is far less limited than the 1zr and 1zz.

2zrfre corollas on corolla9.com have been making it....if i recall correctly

castrex, a member on this board with a TS, pulled the dyno below

40lbs isnt THAT much to add to the front, and you'll be adding that with a supercharger and at least that with a turbo/intercooler setup

n/a 1zz's ive seen will top out about 140whp with cam's....and the cams really suck at low rpms

2zz is a great engine, but only really with the c60. the transmission case is longer than the engine bay is wide in the yaris, so you'll need to notch the frame for it to fit. can be done, but its not typically an in-your-driveway swap.

what im saying, is that since the 2zrfe is available and, in theory, bolts up to a standard yaris transmission, its a decent option for oem-reliable power (in my opinion). a "new" supercharger kit, if you can find it, are about $3200-3400, used about $2000. i still think the 2zrfe swap could be done for $1500-2000 if you can DIY

im still keeping watch for a yaris cheap enough for me to attempt an engine swap

castrex dyno

[xnamerxx]

I've seen that dyno float around many times and its always associated with RichardHoldener but basically its a custom intake manifold, intake, long tube, and race exhaust which adds a considerable amount of cost to the project plus those parts don't exist and no one has been able to duplicate them so I don't believe its real. Most of the dynos fall in the low 120's to low 130's with high 110's being the norm for stock. I'm just saying 140's are unlikely to be seen from a 2zr swap.

40lbs is quite a bit of weight to add for 20hp but even so you still need an all the supporting parts to make it work plus its such a small gain I don't think its worth the effort.

I don't see what the issue with the c50 transmission is, for a higher powered engine the gear ratio's aren't terrible you just need to get a better final drive but that's not even that big of an issue since the weight gain is 80 lbs total for an extra almost 80 hp plus you also have room to grow and the engine has way better aftermarket support whereas the 2zr does not. The only reason I can see someone going with the 2zr is if they wan't to remain CARB compliant in which case I'd just sell the car and buy something else because it would be far easier and less of a hassle to get the power you want and still remain emissions compliant.

Like I said before I'd much rather swap to 3mz or a 2gr or even a 2az before I'd even consider a 2zr engine simply because the gains are more inline with someone who's modding a car would expect for power output.

aucorium ran 145/140 whp/wtq
http://www.yarisworld.com/forums/showthread.php?t=40105

guy on matrixowners.com ran 118whp with intake, header, axleback on a slushbox. that could be about 135whp with a proper transmission. also, keep in mind that the stock matrix/corolla/xd exhaust shrinks down to 1.75" (like the yaris) after the resonator, so removing the axleback/muffler section only would have less gains than adding a midpipe (available now through rpm headers, actually)

anyways, i see what you're saying, the cost/benefit ratio could be skewed. turbo is still likely the best bang-for-the-buck, but i still love to entertain the idea of the 2zrfe swap. i think it can be done on the (relatively) cheap.

edit: this dyno too, slushbox 2zrfe corolla with intake 116whp (could also be as high as 134-135whp with a manual (25% loss assumed for auto vs 13% for manual) - - 116whp/0.75 = 155bhp x 0.87 = 134.5whp manual)

2zz/c60 would also require switching to a throttle cable...and you'd need both the engine and transmission. 2zz's run $1000-1500 and c60's are 500-1000...plus all the other stuff.

for potentialy "simplicity", i still like the 2zrfe

[xnamerxx]

the 2zz is compatible with the c50 and to keep the tb you'd just need to make an adaptor so you can use a tb from a drive by wire car like the tc or xrs matrix.

I get why you like the 2zr swap but looking at it by cost to benefit it just doesn't make sense unless you plan on boosting or something.

The c50 is a 5 speed. You wouldn't want to use it with the 2zzge, trust me. I had an 04 matrix XRS, currently own an 03 vibe GT, and I'm putting a c60 into a 1zz vibe today...

You NEED the close ratio 6 due to the 2zz's peaky/short powerband

X2 but my folks have the '03 XRS with the higher redline. 1st-2nd even as close as the gears are still puts you out of lift for a few hundred RPM shifting at 8300. The 5 speed would be useless with the 2ZZ.

[xnamerxx]

I never found an issue with the Vibe GT transmission I'm sure a close ratio 6 is better but the Vibe GT and Matrix XRS are also quite a bit heavier over the Yaris your talking about a 550-600 lb difference between the Matrix and 800 for the Vibe.

[thebarber]

Again, not sure where you get your info....the matrix vibe twins, except for body work, are identical. The 03-06 Vibe GT, I can assure you, is a 6 speed with a c60. The XRS/GT both weigh 2800lbs or so.

Its the 09+ XRS/GT that have the 2.4L 5 speed (same as the Camry/tC/xB2) with a beefed up curb weight of 3000+lbs

Bluevitz, you can land in lift 1-2 with the 03 lift of 6200rpm (I also used to have an 03 ecu in my 04 XRS) you just need to run it to the limiter and powershift into second...

Its only the celica's that really varied their redline from 8200, 8400 fuel cut. But to the best of my knowledge the always had lift at 6200rpm. 03 vibe/matrix was 6200, 04 6500, 05/06 (including Corolla ) was a useless 6800rpm. The corolla was actually pretty quick still due to 2500lb curb weight.

[Bluevitz-rs]

I'm just talking normal shifting 1-2 from limiter drops it down to around 5900-6000. Just under lift for a few seconds. The 5speed would be down to 4xxx for sure.

Shred. Only person I recall using a 5peed with a 2zzge was a guy screen named war in Alberta (iirc the location) had an imported MRS and built up the 2zz for turbo. He wanted Tue wider gears of the 5 speed since lift didn't matter for his setup and he raced on track, so less shifting was better

Has anyone thought about a fwd Sr20de engine from like an Infiniti G20 or a bluebirds nissan series?idk just a thought.

[ilikerice]

I am sure everyone has thought of every motor imaginable.

ANY motor swap is possible if you have the resources and funds. esp. from a different manufacturer. cant use the same ecu, would have to go standalone. custom everything from mounts to shift linkages, axles, exhaust, hoses. Again, its possible. just ridiculously expensive if you don't like wiring and welding and alot of trial and error
