Default Re: Honda Brio: 1.5L Engine Swap (L15A / L15A7)

I own a 2014 Brio and was in the same dilemma as to how to boost up the power. First thought was of going the turbo way, and then got interested in the supercharging options available. As you mentioned Honda's are famous in Thailand and lot of people back there have supercharged their Brio's, but unluckily I could never get all the parts sourced required for the build. The thought of an engine swap never came to my mind and I am really interested in seeing the end result.

All the best with your project

Well.. That really escalated quickly. From 6 year old City engines to a 2 year old JDM one...

What engine is this? How much did you pay for it? Whats the donor car?

You are doing what Honda should have done for the Brio . Gluing to this thread and can't wait for the updates. Whom are you entrusting the job to be done? Any performance mods planned?

What about the ECU. Will the brio stock ECU fit to the city one. You might need wider rubber for the new found power. And bigger brakes. You know, with great power comes great responsibility. I think you should get some good alloys when you are at it.

And what are you going to do with the old engine. This makes me think of only one thing. Use the old engine, stock tyres and a custom made roll cage to make your own go-kart/buggy/whatever you like to call it.

Only if I had all the money in the world to have my own private estate to play with it.

This is an L15A 1500 cc Honda Engine.
It is the EXACT same engine that comes on the Honda City.
The donor car is unknown, but the serial no. says that the car could be manufactured anytime between 2015 and now.

Performance mods for a Gasoline engine are limited. I already have an Automech Exhaust. I also have a K&N replacement filter.

One thing that really intrigued me was the following:

My stock intake design looks like this
Honda Brio: 1.5L engine swap successful (page 7)! Now with RD ECU & larger injectors!-20160714_163102.jpg


It also has a flap in the bonnet that directs air into the intake.
Honda Brio: 1.5L engine swap successful (page 7)! Now with RD ECU & larger injectors!-hondabrio02.jpg


According to me, this is a very crude way of sending copious amounts of cool air into the engine.

The original adage that says, "What ain't broke, don't fix it!" And Honda did just that. They FIXED It! The NEW design of the stock OE Honda City, Mobilio and the BR-V, that share the same engine, just prove that Honda didn't find something right in the way air was being fed into the engine. The new intake design looks so convincing. The best part about it is that it's a PLUMBED COLD air intake designed FOR this engine.

If a company thinks that it's the best way to get air into it's engine, we stand by it. There is no need to go and experiment with anything else. Hence I am on the lookout for an airbox and intake unit from Honda and have put in a request for it through a friend.

That question can only be answered once the engine is in the bay and we crank the car on the current ECU. If the car runs on it, then the next challenge is to get the ECU remapped to run a 1.5 l engine map.
This seemed like it would be manageable but the pictures of my actual ECU have actually thrown things into a conundrum. A Keihin ECU is easy to map, apparently. And most Hondas these days are coming with the Keihin.
But my car has a MOTRONIC (a Bosch subsidiary) ECU and only time will tell if the car cranks on this ECU and if it does crank, then it's only half the battle won.

Tomorrow's plan:
The car will go up on the Dyno and we shall measure what the current L12B engine makes. I am actually quite keen on saying HOW off Honda is, from that promised 89 bhp and 110 nm. Also, I do have a 'performance' exhaust and It will be entertaining to see how many Bee ech pees I may have lost or gained after adding the same.
Tomorrow is going to be a day of enlightenment!

Also, tomorrow the L12B engine comes off the car.


More updates tomorrow!

Are you sure about the manufacturing date? My 2015 Honda City has the L15Z Engine series. How can an L15A make it to a car that has been manufactured in 2015?

The l15z1 series is the same engine with a few changes.
The l15z1 was introduced last year, replacing the l15a series. So it's likely that this is among the last batch of engines of this nomenclature.

Beg to differ here.

If this modded car is going to be used on public roads, it absolutely needs to have the entry made in RC.
Its not as trivial as "who will check the engine even in case of a traffic violation".
Apart from the legality aspect, Insurance claim will get rejected (if the surveyors find out, which he/she will).

I agree, how about just the third party insurance after the swap is successful because insurance claims are always difficult on modified cars.

Warranties are out in any case.

Also just for personal information - will Honda carry out regular service to this car after modification?

Cheers

This just in. I am shocked at the Dyno results


These are the Honda specifications:
Specifications:
Max Power KW[PS] @ rpm 65[88] @ 6000
Max Torque (Nm @ rpm) 109 @ 4500

And this is my graph.
Honda Brio: 1.5L engine swap successful (page 7)! Now with RD ECU & larger injectors!-frank.jpg


The power figures are right up there, but I think the 'performance' exhaust is responsible for lower torque figures.

This is a lesson for everyone including me, who thinks that eliminating the catalytic converter and putting out a straight pipe in it's place will increase performance. Engines these days are engineered to very tight tolerances, and backpressure from catcons and air intakes etc are designed in tandem to deliver performance together. Mess around with one, and the whole thing is thrown into pandemonium.
Which the graph above demonstrates!

UPDATE on the Swap:

Engine swap has started. Old engine will be down today and new engine install will start from tomorrow onwards..

An eye opener indeed. Torque, even while being served at higher RPMs, plays a good role in vehicle performance. One thing the sports/performance exhaust (especially badly designed ones) does is to give you placebo effect of going faster due to its sound effect! A Dyno is the only way to confirm the actual results of the modification and I am glad you shared this with us.

And the 1.2 engine is OUT.

Some complications with the ecu but i will reserve my comments till the new engine starts up on the current ecu and a dyno test will throw up the results.

Frank how about the engine mounts for the new engine? Are they similar or the location has to be changed? Seeing your project I am not interested in my cousins Brio which he might sell some time. Personally I am of the opinion that if this is going to be a straight swap without structural changes, it will be an excellent sleeper.
