2001 Toyota Yaris T-Sport Engine Swap

[dylanwild]

I have got a 2001 Toyota Yaris T-Sport with a 1NZ-FE and multiple mechanics said the engine needs replacing. I kind of want more power out of it so was thinking of doing an engine swap. I have little to no mechanical experience, I want to learn about mechanics so I was wondering whether it was worth learning by throwing myself into the deep end and trying to figure out how to swap the engine myself or if I should take the car to a mechanic to put another 1NZ in it or take it to somewhere specialist to do an engine swap for me.

Only do this if this is a car you do not need, as going down this path will likely take it out of action for an extended period!!

It will become your Project car, aka an unending hobby-slash-moneypit that someone who takes pity on you may call Car SOS to finish for you just before you pop your clogs  

Most decent mechanics will be able to do a straight like-for-like engine swap, and there are jappy car specialists who can advise on upgrades/swaps better and do the work, but this will be extremely expensive.

DIY will take forever as you will need to 'learn on the job' and you really need a friend or two who's also into such things who can help out, but could be a fun hobby and you'll learn a lot (Including a whole repertoire of new swear words!  )

Haha thanks, I think I'll give it a go myself then and turn it into a project car. Wish me luck!

Try looking at this project Yaris, lol.
I think the playlist has the episodes out of order, though, so it may be a little confusing.

The hardest part will be the electrics with a swap tbh just change the engine

Short answer: Just get a replacement 1NZ

(slightly) Longer answer: Before you decide or do anything, find out what it is you want to achieve. Go faster around a race track? Outrun the local moped hooligans? Be first away from the traffic lights? Or just a talking point at shine&show meets? The thing is, fitting a different engine touches on so many things and requires so many answers: Which engine will it fit physically? Does the new engine mate with the existing gearbox? If not, which one will? Will the new gearbox work with the existing driveshafts? Are the driveshafts the same length? Will the new driveshafts fit the existing hubs? Which stubs could be used to build a mongrel driveshaft? Can the ECU from the new engine plug straight in? Which sensors need to be changed / are missing? What about meter readings? and the list goes on and on...

Here's the thing - the 1NZ is a good platform. If all you want is "more power" then there are plenty of ways to get that out of the 1NZ. All of which will be easier than doing a complete engine swap. The engine is fairly durable and easy to get hold of. There are plenty of parts for it; camshafts, pistons, induction kits, turbos etc. Jenvey even make an ITB kit for it. There's no reason to cross the river to fetch water.

Secondly, depending on what you want to do, more power is not necessarily the answer. Considering that the car is front wheel driven and already struggles to put the power down from the 1NZ in standard tune, one of the mods I'd do before tuning would be to get an LSD. To go faster around a track, the first thing you should do is to get a good set of tyres, good brakes, and then maybe start looking at suspension components. The T-sport is surprisingly good 'as is'.

Wearing my "old and wise" hat; Do not underestimate the mental challenge of a project like this. Working on cars is meant to be fun. Jumping in the deep end and taking on too big a project can easily lead to loss of motivation and enjoyment. Doing smaller jobs like suspension upgrades, new camshafts, exhaust, ITBs etc allows you to see progress along the way and you can enjoy each stage. Of course, if you've got the money to get someone to do it all for you then nothing is difficult. Neither is it particularly rewarding.

Might be easier to buy a new one and keep your existing t sport for spares. That way you've got both a car to enjoy and one to learn on. Space permitting of course..

What did he say was the specific issue? Its not a hugely complex engine with loads of sensors everywhere, and there's a good technical resource here if you get stuck.
