I want some judgement on my plans...
This is my current ( and lame ) setup:
Cheap tires ( 205/55 R15 ) ; Stock suspension ; TSW rims ; Stock headers
Straight exhaust pipe ( cat off ) ; Custom muffler ; Prototype CAI ( sucks hot air ... )
MazdaSpeed groundwire kit ; Stock sparkplugs ; Stock spark wires
I started off with a slow car ( it still is

) with only 120bhp full stock
With my changes and a better use of the car, the numbers raised: 136bhp
I am planning this setup for soon, tell me your judment about this , and what should i expect ?
Toyo Proxes tires ( 215/45 R16 ) ; Lejofors springs ; KYB shocks ; OZ Ultraleggera rims
OBX headers ; Straight exhaust pipe ( cat off ) ; HKS muffler ; RocSpeed CAI
MazdaSpeed groundwire kit ; Denso Iridium Sparkplugs ; Kerr Nelson K1 10mm spark wire
Bored out intake manifold ; Full remapped ECU
maybe 150bhp ?
what do you guys think ??
