Max power including flex fuel isnt that common cause most people dont use flex fuel or will probably limit the ethanol they run as various posts here indicate that anything over E10 causes some kind of issue sooner or later. Truth be told, ~1500$ for a 20-30hp gain is a lot of money when W1 can go much much further. Reliability is costly and reliability doesnt come only with with quality but also boost. The more boost, the more likely something will fail, starting with the rods. The TD03 cant run as much boost as the W1. I wont compare the PRL big turbo cause both TD03 and W1 are "bolt-on", meaning you can run any downpipe and any intake.

If you go FBO and TD03 on 93RON, I guess a slight torque shift to higher RPMs and a max power of 250-270hp (engine, not whp) is possible. It looks like the TD03 is the perfect option for the non-Si, as their rods arent as strong. If I had an Si, I wouldnt really consider it against the W1.

If someone will sell the TD03 including all necessary hardware and confirms that it will fit any downpipe that fits the OEM, I will most likely go for it (and then try to figure out the intercooler and the piping...)

I thought it was more than 10% ethanol content. people stay under 40% (usually 30-35%) ?

full race updated the description on their website:

260whp with stock fuel system
plug’n’play conversion only small adjustments are necessary.

I am not too familiar with flex fuel, I base what I say onwhat I ve read here.

260whp verifies what litoto17 said. Max 300hp, more likely 280hp motor. I will not bother with anything that is not bolt-on. I need to see more on the "small adjustments".

Well to say TD03 can't run as much boost as the W1 is false information. Most people with W1 including myself push it at around 29 psi and some can go even a little further with a 4 bar map sensor and some meth injection. On our stock Si TD025 turbo a lot of people max out at around 27-29psi so yeah it could run as much boost on stock map sensor. As for as quality the MHI should take it as it's oem and everyone know's their built to last far more than aftermarket as said by DRob and EMan. Another thing to mention right now is quite a few people with W1's are experiencing blue smoke when turning right and boosting which is a sign of oil burning through the turbo oil seal or even thrust bearing failure.

This turbo is a direct bolt on with no modification's needed. It's literally made by the oem brand of our turbo on our car's. Just better upgraded larger billet wheels this time around.

One thing is boost and other eficiency and power (yes, most of you know :p). So it may boost to 29 or more psi but wont make the same power as bigger turbos. Im waiting for someone to test this and then decide between the 27won or the TD03 DBO.

What worries me is the "small adjustments stated in the website. I do my mods in the Honda dealership (they are cool like that), but I need to bring them everything needed and do not have the time to search for missing parts or leave the car there as its my daily.

Having a CRV which for the EU means Si engine overall apart from the non-Si connecting rods, the TD03 would be an excellent option for me. The price doesnt put me off, having the stock IC with no bolt-on solutions does. I ll contact an official EU dealer to see what they say about fitment.

Seems this would be a likely upgrade once the stock turbo decides to take a dump tbh.

I d do it but find it a bad idea to install it with the OEM Intercooler.

You are right, I didnt express myself correctly, my english aint perfect. What I meant is what kytos wrote, about efficiency. Anywayz, the TD03 seems to be a decent option.

I don't think it's a major problem as it will be more efficient at the same power level. The problem is you will have to upgrade the intercooler at some point and custom tune again (I mean, for more power)

That's why you do all the supporting bolt on parts first before upgrading turbo lol.

This is pretty cool news. MHI turbo's are 100% the bee's knees. Nice to know we have a just as reliable as factory option for replacements down the road that will provide some benefits even on a stock car.
