aw11 swap for 3sgte - Toyota Nation Forum : Toyota Car and Truck Forums

89MR2kid · 06-17-2011, 12:40 AM

Ive been wanting to do some upgrades to my aw11 and was originally going to upgrade parts on the 4age motor. But i was looking into and i couldnt get much power gain if i did that. So i looked up the sw20 turbo engine and thats the power i looking for but i like the aw11 body better and ive heard of people swapping engines and was just curious to how hard it will be and how expensive it will be? im going to buy both the transmission and motor and then take it to a shop to be rebuilt and then maybe bore the pistons and other stuff. i heard that to do this swap you have make special motor mounts, how expensive would that be to have someone do? and how much would the swap overal cost not including the rebuild?

Thanks,
Zach

Go to mr2oc.com. There is a section on MK1.5.

not counting the engine/transmission...

the hubs OR hub carriers will need to be replaced to fix the turbo axles.

you'll need to have the factory side engine mounts cut out of the chassis, then have another set welded in place (www.speed-source.net sells them). roughly $450.

the fuel tank will need to be dropped and the fuel pump will need to be upgraded. Walbro 255lph pumps go for $90 on ebay.

you'll PROBABLY need a custom exhaust setup (ie. midpipe and muffler). i would GUESS about $200 or $300.

of course, you'll need the wiring done to mate the sw20 engine harness to the aw11 body harness (phoenix tuning does this). $400 is the price that phoenix tuning last quoted me (absolutely worth it!).

those would be the most expensive (and largest) portions of the swap. you can make your swap as simple or complex as you like, of course. and that does impact the overall cost of the swap.

That is an expensive swap idea because you are looking at somewhere between 900-1200 for the rebuild kit for the engine alone plus labor on top of it, tack on about another 1k for the tranny rebuild. You are going to need a ton of money for this kind of swap.

After that, he'll have a car that's a TON of fun and has a basically brand new powertrain. I'd say it's well worth it. I also don't think I'd bother with a rebuild if everything eks out okay (compression/leakdown test and good synchros in the trans). A stock 3s-gte in a mki is a riot.

most people on the road could barely handle a mildly overboosted supercharged MKI Mr2 (roughly 160hp), let alone a 200hp MKI Mr2.

i think the 'cool' factor is winning over the 'realistic' factor with this swap for most people.

You guys are making it sound like a real giant PITA and costly. Honestly you get yourself a hand on either a donor crashed mr2 turbo or a clip and you are looking at a generally cheap and easy swap (compared to others). There are over 50 people on mr2oc that have this swap. There are companies that actually make the mounts required with kits to help you get it fitted correctly

Like BDSL said, look in the MK1.5 section on MR2OC. There is a ton of info about the swap on there

uh. it IS a PITA and costly.

ask those 50 people how much it cost them for the swap, and not 'oh, not that much...' but actual $ amounts.

as a point of reference, i am putting a 3sge into my AW11. i have done what i think is reasonable to my swap, others will disagree. i have dropped over $6000 into it, and i'm still not done. i do believe i even did a price breakdown too.

anywho... i checked Speed Source just before posting below, to make sure that the numbers i post are as accurate as possible.

http://speed-source.net/
MK1.5 engine mount kit:
$190 (plug shipping) for the left and right engine mount kit.
$285 (shipped) for the front and rear engine mount kit.
=$475 (not counting shipping from the left and right kit)

and if you want to use their 'jig' to make sure that the left and right engine mounts are placed correctly, that is $500 - you DO get the $500 back once you return the jig. that also does not take into account how LONG you have to wait to get the jig.

none of that takes into account what it will cost you to have the original left and right engine mounts CUT OUT of the chassis of your AW11.

and again, UNLESS you start with an SC AW11, then you will NEED to swap over the hubs, as the NA hubs will NOT fit the turbo axles splines. that boils down to MORE MONEY. how much depends on where you get the hubs and what kind of deal you find.

so... its not as if we are posting 'hey, this is a big project' without reason. we're posting that 'this is a big project and WILL cost a decent amount of cash' because 'THIS IS A BIG PROJECT AND WILL COST A DECENT AMOUNT OF CASH.'

well one of the guys in my area had a nice donor for the whole thing and i think he only spent about 2-3k on the whole project.

you are counting on the very unlikely situation that someone gets a donor setup that is not raped, abuse or destroyed.

for the other 99% of the people that go through swaps of this nature or any other, the price tends to be higher.

so, in short, if you do not wish to put forth a realistic situation or rough price, then state as such.

This link is to the mr2 forums where someone is doing a 1.5 MK1. Even with a perfect donor in hand be prepared to have a good sized budget.

I am doing a Silvertop 4AGE swap into my MK1, including the cost of the motor...I have spent about 3.5k so far on the swap. And my motor bolts straight into the tranny and motor mounts, so it hasnt had alot of work as far as fitting wise compared to your swap that you have in mind.

We are just trying to give you a realistic outlook on this swap.

That is the ideal situation, more than likely though if he is getting a donor car for the swap then there is something wrong with the car. In most cases the donor engine and/or tranny probably need a rebuild hense its a donor car.

Realistically if he goes with a donor or even a jdm motor I would have a budget of somewhere between 5k to 7k for the swap.

whoah dude, calm down.

#1.... SC and n/a hubs have identical placement and outer splines. There is a variance in the rear suspension in which the hubs are different -- but that has nothing to do with axles.

#2.... the cost will all depend on his, and friends who help, ability to weld, wire, and fabricate. Further it will also depend on who what he pays for the motor/trans

#3.... as I said in your post I'm gearing up for a 5sfe swap. Though not a 3sgte (this is a much easier swap) I am looking into a couple options on how to install. One way, which was done successfully on a v6 aw11, apparently, is to create brackets between the stock mount and the new engine mount. I will be looking into this option as it may not require any cutting of the chasis.

For my 5sfe/s54 SW20 swap into the aw11 I'll be looking to have less than $800 total... including engine, transmission, wiring, axles, hoses, etc. Your $6,000 price tag is because of how meticulous you are and that many of the items you're using are quite expensive.

$450 for a full 91 motor/trans out of an SW20 (picking up today)
$85 for ecu, sw20 wiring harness, and sw20 coolant filler neck

Expecting to spend around $50-100 at a pull-a-part to get the intake side alternator/bracket and maybe some various mounts to see what I can make work.
$100 on an ebay 5sfe header... unless I can find a 3sfe rav4 in the yard...... however if the motor comes with a good cat I'll get another $40-50 returned just by taking it to the scrap yard.... probably paying for any metal I might pick up.

The speed source mounts are extremely useful. Don't get me wrong. However I cannot fathom spending that kind of money on about $30 of scrap metal and a couple hours of welding. The jig isn't necessary if you know how to use a tape measure. Those are definitely useful tools but I don't feel they're required.

other than potential future "costs" if you decide to not have an mk1.5.... cutting the stock mounts out of the side would cost about $5 in blades and 20 min or so to get 'em out.

^^thank you, thats all i was trying to say.

not12listen · 06-29-2011, 01:44 PM

toyotaspeed90 - i do understand your point, that you can do a swap, and NOT have it be expensive. my point is that you seem to be over simplifying it.

last i checked, the SC and NA axles have different spline counts. if i am wrong, then my apologies. i do know that the SC and NA axles are completely different on the inner portion (where they mate to the transmission), but that would only matter if you're swapping the transmission.
