i am new to jdm was worked on classic chavys and fords for 10y

I have Honda accord 1.5 turbo Cvt . I I think to Swap up The transmission to manual transmission or 10 speed
with custom shaft base and separated AC for the cooled air intake and engine oil with hks blow off valve , i know it sound crazy idea but just want to start a suggestion
am thinking to make +250 hp from that with new custom crank shaft and hodata or ktuner
and weight reduction 4 carbon fiber parts (hood , fenders and trunk door ) 50 to 100 kg weight loss

It will probably be cheaper and easier to look for a 2.0 in manual or 6MT. By the time you purchase transmission, harness', and all ancillary parts to make this swap you would have probably paid more than just ditching the 1.5 and upgrading to the 2.0.

what do you need a custom crank for, are you trying to stroke it out to a bigger displacement? You could theoretically source a manual out of another 1.5 and sway everything over. the 10 speed would be harder because you'd need an adapter between the block and bell housing. the L15 and K20 aren't going to be outright compatible with parts and transmissions.

Cheaper to buy a 2.0T or 6mt. Not worth the fab or headache.

Take advantage of the HOT Pre-Owned vehicle market and sell your 1.5T CVT Accord. Put that money towards whatever you would like more the 10AT or 6MT. Going to be cheaper this way, no labor, no parts to attempt to source, no custom work needed, and most importantly peace of mind driving with a 100% compatible engine and tranny combo.

The CVT to 10AT or 6MT is a massive upgrade but the 1.5T to 2.0T is also a massive jump in capability and performance. I don't think you will regret it. Also, I can say the 10 speed auto is one of Honda's most impressive automatic transmissions yet. And we all know the 6 speed manual speaks for itself, it seems to take whatever you can throw at it.

I like The L15 series engin more than 2.0t k series, and we dont have manual transmission on honda sence 2009 so a manual transmission on a The 1.5t is a big deal.
I thinck The L15 series has a good Potential

The L15 series engin designed to Work with The CVT s at 6750 RPM Red line. With The 6mt it goes more than 7000 RPM Custom crank to adapt The engin performence on the transmission.

Well if the L15 series engines are what you prefer then I say go for it! We're all car enthusiasts and we all have different taste, you should embrace that and build exactly what you are wanting! If you have the time, money, talent and patience to source the parts and do a custom manual swap you would be a pioneer in this regards and I think everyone on this forum would enjoy seeing the progress and work you put into making it happen!

Yeah, so you're looking to stroke out your 1.5 to a 1.6 or 1.7? I get wanting to squeeze some extra rpms out of it, I just think this seems like a lot for a fairly new platform. Where are you from? I see you said there hasn't been a manual offered on a honda since 2009 where you're at

Is this a troll?
Someone is gonna tear apart a new Accord, change the transmission AND CRANK, plus figure out the electronics just to get a different transmission with a small motor? Just the rental car cost for when the car is apart would stop the project for me. Why not just buy a new Accord? Or if you really want the 1.5L, why not get a Civic Si or Type R?

to adapt the transmission to the engine

a was thinking to design a 3D one and 3D metal printing it
but the K20 the 10 speed, i agree with you its more difficult

my be the 1.5t 6mt crank fit easily .
