Hey , i have an 02 R53. Ive only done
M7 CAI
ALTA 17% S/C PULLEY
ALTA CRANK PULLEY
HOTCHKIS LCA
POWERFLEX BUSHINGS
H&R RACE SPRING
Some weight reducing , seat , wheels etc

I wonder what would be the next thing to do? Plugs ? IC? What are the things i need to do before go into compression mods. Cam?

 

Looks like your off to a good start! I would look into IC and exhaust

 

I forgot to list it up , ive done my exhaust. Custom made though. I not sure if my car have a good cooling system or it is just pretty cold here in Malaysia because everytime i cruise or pedal off my temperature goes down to maybe a little less than 90. A bit more from quarter on the temp gauge.

 

Cranks?!
I think you mean CAM!!
Determine WHAT you want...and build it to that! You want a bit more go, a bit more Zip, or better steering? Or just want to spend money?
Lots of stuff to do, But EVERYTHING has Tradeoffs....
Tradeoffs, like street-ability/drivability.
Some mods will help HP at the top end, but may make the lower end less fun....Cams, and BIG VALVE HEAEDS are in this category....
So the question is WHAT do you want to do with the car? How do you use it now or plan to use it in the future?
A Daily Driver is VERY different from a dedicated track car...
Do lots of commuting? Mind exhaust sound or Drone?
Live in an area where the car gets inspected for emissions?
Many questions!

 

Oops , editted that.
Well its a daily driven car , i just want it to go more futher. 250hp maybe?
I think my current exhaust setup is pretty fine with my current mod. Havent done any dyno run though. If i was to do my cam. What are the things i should do before going to cam , head , piston ?
