Hi guys! I'm new on the forum, my name is Jan Kenneth Steinsåker and I reside in Norway, Europe. I've got an '88 6th gen Galant (one of the first 6th gens).
I need some ideas on how to get my Galant to produce around 150HP instead of the <110HP it's doing now. The manual states that the car has 109HP, but I'm guessing the engine's mileage has worn those HPs down a bit
It's a standard 4G63 SOHC. I'd rather not do an engine swap or a DOHC head conversion, as parts/engines for that would be hard to come by in my country. I know the DOHC 16V head would give me 145HP, but it's nearly impossible to get one over here.
As you've probably figured out, I'm not after insane HP figures. I just need to have the engine make some 150HP so I can get real value for my money when adding nitrous. With nitrous, I'm aiming for 180-190HP...
I plan to replace the original air filter box with a KN or Raid HP cone air filter setup and custom make my own stainless steel tubing for it. This way I'll be able to place the cone air filter element right behind the front grille or in very close proximity to it and add some velocity to the air that is fed to the engine. But how much can I expect to gain from this simple mod?
I understand HKS makes a replacement cam for the 4G63, but does anyone know whether it's compatible with the SOHC Galant engine?
HKS also carries metal head gaskets for the 4G63, so I'll ask again: Will these fit the Galant SOHC?
What about swapping the original injectors for ones with larger capacity - will that affect HP output, and in particular - how will it affect HP output when combined with the cone air filter element/increased air velocity?
Larger injectors are made by a company named RC Engineering. Has anyone got any more info on this company?
Any and all ideas/help on how to get a little more output from the engine will be greatly appreciated. I really need to prove the Galant's potential to the locals
Thanx
Jan Kenneth
