BTW: I know it's better to install another engine, but that's not the idea of this project, I want to get the most out of this engine because I like 1.4s. 6N is my dream platform, I like everything in it!

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Hello everyone, I decided to ask you what modifications it is possible to make on this engine?

I''d like to have MPI system!

For a start, I decided to start with the following modifications:

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

272 or 276 cam

Porting and polishing the cylinder head

Custom intake manifold with universal 65mm or 1.8t throttle body

Exhaust cut off valve

Chip tuning

Ramair intake or HKS mushroom filter

flywheel lightening

Omex rev limiter for launch control

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

I have the following questions:

Can i install ABU or AEE cam and will there be an increase in power and torque?

1.6 crank on 1.4 block and maybe 1.6 head if necessary? I read in a forum about 1.6 with 2.0 crank and pistons and that's why I decided to ask!

Can i put itbs but with MPI?

Can i put bigger injectors for more fuel and better fuel pump and will there be any benefit?

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

I want to have 100-120 or more HP! 

i''d like to have low end torque that have now if it is possible!

Thanks in advance to everyone who responded and helped with the project!

itb would be = mpi...each throttle body would have its own injector , wont run on standard ecu

 

no gain in oversized injectors , you would need to view the duty cycle at full load/revs and see how much reserve the is  

For all those who think that the topic will end at once I will assure you that I work constantly when I'm not at work and for now things are going slowly. Аs modifications to the engine I installed Cold Air Intake, accelerate the car for almost a second faster than the standard acceleration time, and before I had a brand new factory filter. I think the selection of the size of the pipes is very important, mine are 63mm, the filter is 70mm(RAMAIR cone filter)

In my opinion hate is a bit unnecessary for cold air intake on older cars. I will soon install a 1.4 AFH throttle body because my throttle started to cause problems.Тhen I will install a cut off valve directly to the manifold.I am currently working on the exterior because I want to fix the rust and make it a bit like a rally and hill climb car.

Hey, hows it going mate? I have some plans to do something similar, i kinda want to go with cbr600 carbs but we will see.
