Morning gents,

Hope ye are well. Unfortunately my 2008 invincible decided to break my heart this Christmas. Long story short, i have had to get new engine, injectors and decided while i was going that far to get a new turbo etc.

I've tried to look online for any advice or information with regards breaking in a new engine for this model and unfortunately can't find much. A couple of brief things only such as "no towing for the first 1,000 miles". Can any of you advise? Since its invincible and has the power box, i assume it might need that tiny bit extra care since the new engine would be putting out more power than the standard. I'm good anyway with regards servicing the jeep on when it needs, leaving it warm up and cool down etc.

Thanks

As you have already stated in driving it , drive it normal is  best way to break it in , as for a tuning box that is not standard for a 2008 invincible , the 2008 version is based on the LC5 with even more extras , so if your 120 has air suspension at the rear it is not the LC4 invincible with the tuning box , toyota stopped fitting tuning box/power chips because it was found to contribute to cracked pistons due to heavy extra fueling creating a very hot internal temp and extra pressure on the pistons , so if your 120 has a  chip/tuning box on a air suspension 120 it was added by the owner ,

They were not power boxes made or issude by toyota factory in its self ,  but by toyota GB who sold an LC4 model with and aftermarket power chip box made in Germany and had printed the toyota logo on the chip box , but after the cracked piston issues on these LC120s and hilux that also the chip box on some models were all dropped and the new version  of the invincibles were based on extra equipment only .

Sound info again Tony. 👍

I think after getting a new engine (how much did it cost, if you dont mind me asking), I'd be tempted to ditch the tuning box to make sure it doesn't happen again!

[TONYCY11]

I agree with Karl , there are better ways the get your engine more responsive and more pep in the 1kd  120 engine that actually help the engine last a longer life span and with better economy than risking destroying your engine with tuning chip boxes that all they do is  over fuel the engine causing stress on the pistons that can end up cracking them or blowing a hole in them .

Agree with the lads, i'd have that tuning box out.
Its probably a Steinbauer unit and would sell rapidly.

You already allow the engine/turbo to warm and cool sounds to me like you already know how to treat that new engine for the first few months, i would go old school and give it a first oil  change at about 1000 miles, don't know if you have to follow some service regime to keep the engine warranty intact but might be something to read the small print on.
