Toyota estima engine swap
Discussion
So first post so let's get it going.
Iv got a (free) 93 jap import estima 2.2 td. Not the best thing in the world but it was free so,
Basically the plan is to strip it down (already done 90%of that) and cut out the rear floor behind the c pillar and fit a..... Honda a k24....
Yeah not a simple swap but why tf not.
It's not a pretty vehicle and is actually the second one I own, iv got 6 kids and needed a minimum of 8 seats so choice is limited as I don't want a van.
Anyway the plan is simple, remove everything I don't need and sell to raise money for the engine swap. Its a honda accord with a k24 that's the engine donor.
The bodywork is the last thing to be done as its the easiest, basically stock looking with nice wheels, the goal is 400hp with a k24 turbo setup. More photos to follow

As you can see it doesn't allways go to plan, I removed this engine on my own in my drive
Gutted the interior to get the wiring loom out was a pain
Oh look I can see across the street.
Cyl 1 is ok... Ish, if you close your eyes
Cyl2 is about the same
Oh.... That's not good, major scoring and a snapped piston ring for cyl 3
Cy4 was probably the best of the bunch tbh
Atleast the bearings are good.....

Will be interesting to follow this.
My parents had the UK equivalent Previa, same platform but wider than the Lucida you have there. They weren't very complimentary about the handling, so you may want to consider chassis improvements in due course ;-)
Any reason you're planning to cut the floor out at the back, rather than mounting the Honda engine in the stock position under the front seats? Seems that would be easier, but maybe not? 400hp sounds good, the stock 2.4 petrol engine was always a bit underpowered for a fairly heavy car, exacerbated by the engine being under the cabin so you heard its exertions loud and clear. Cabin was a nice place to be though, great views.

Yeah the handling is honestly about on par with the other mpvs iv had (mk1 galaxy, zafira a, b) just a little softer. Bc coliovers and some other mods are on the cards to help with handling.

132-135 hp for the 2.4 petrol and 100ish hp for the 2.2 turbo diesel isn't much in a 2T car especially once you stick a bunch of kids in the back and all there crap. Put it this way I'm not winning any races unless your walking then it might have a chance.
I had thaught about fitting the engine in the stock position and it would be alot of work as the oem engines are tipped over at 75 degrees and I doubt I could make the honda engine work happily at such an angle without serious modifications.
Oem 2.2 td engine, yellow arrow is the "bottom" of the engine where the sump is normally but the orange arrow points to the actual sump. Its just a normal toyota 3ct engine that's been tipped over and another sump stuck on the side, same with the petrol 2tz fe engines.

Interesting build. From what I remember of these, the engine was pretty much underneath you from the interior and space was limited.
Interior space is actually really good, it's got a really flat floor from the b pillar back. Yeah the engine is directly under the front seats and that make services on the oem stuff interesting, my daily is a 2.4 petrol 4x4 version and you have to remove the drivers seat, carpet, half the floor just to get access to the spark plugs. Oh yeah, of course, lubrication could be an issue with the engine tipped over at 75 degrees! I know Honda ran the F20C in the S2000 leant over, but nothing like as far as that so probably would need changes. Can see that making space to put it in upright will be easier. What's the plan for the gearbox? Engine far enough forwards to have a conventional inline gearbox between it and the rear wheels, or a transaxle unit?

The plan is to use the standard honda engine/gearbox combo, subframe and suspension. Essentially the entire front end stuffed unter the back Yeah the Honda all lean over a little but 75 degrees is mental, might aswell have made it a full 90! But I'm not gonna argue with toyota engineers..... Just gonna throw there work away and use honda instead!

Oh yeah I get it now, transverse engine, take the whole lot from the front of a Honda and drop it in the back. Just like how the Clio V6 has a Laguna frontend behind the seats, whole lot just with the steering locked out. Makes perfect sense.Yeah the Honda all lean over a little but 75 degrees is mental, might aswell have made it a full 90! But I'm not gonna argue with toyota engineers.....

In terms of handling, obviously putting a the engine weight a bit further back, I guess the conventional thing to do would be to fit some slightly wider tyres and wheels on the back - but it may be fine anyway.
As I understand it, by inclining the engine at 75 degrees rather than 90 you leave just enough space for the exhaust manifolds to come out of the head underneath, thus keeping the crank height low compared to having the cylinders completely horizontal.

Yeah that's the one, make up some adjustable bars to lock out the steering. I'm going to have to try and drive it in a circle with both axle cranked right over just for sIn terms of handling, obviously putting a the engine weight a bit further back, I guess the conventional thing to do would be to fit some slightly wider tyres and wheels on the back - but it may be fine anyway.

ts and giggles.Wheels and tyres are gonna be some nice looking ones no idea what ones yet though but I'm going to slap some good tyres on the oem wheels and go for the sleeper look as the exterior is that last on the list and isn't going to change to much
The engine setup makes sense, like you say the exhaust has to go somewhere.
Did you know that the petrol ones come with hand made tubular exhaust manifold, stupid bit of trivia for you.

Brilliant effort! What is your plan for the ECU?
The plan is keep it stock till its driving/Road legal but I'm probably going to use a hondata or a haltech depending what direction I want to go regarding function. Once it's drivable and Iv worked out any kinks in the setup then the turbo/injectors and other bits will be bolted on and sent to the dyno for all the boost...... Well a little boost to start with...... Probably....

I guess this never played through then.. been keeping an eye for ages for ideas on my estima
The 'sensible' performance option for a Mk1 Estima is to fit the supercharged engine which was offered as an option in North America, since it's factory fit.The more ambitious option would be some kind of V8. People want to go for the 1UZ to keep it in the family, however I wonder if an LS might be easier as a pushrod engine will be less tall, so more likely to fit in the stock location beneath the seats.
