Hi All, new to the forum and impressed with your threads and information shared. Have a 2003 SC430 stock, Silver exterior, off white interior. Purchased the car used a few years ago. It is now time to customize and improve this great ride. Do any of you have a list of recommended updates to increase the horse power and improve the handling?
There are a ton of threads about suspension and engine tuning here. I'm sure that several of the members will be sharing their favorites here shortly though also.
Things that I would recommend in order of importance to improve the SC430 all around performance.... just my opinion. You can search the forum for more details on specifics on each.
1. Trans Pressure Mod
2. Rear ISF Sway Bar upgrade with Polyurethane Bushings
3. Weapon R Cold Air Intake with Ram Air Kit
4. Sprint Booster
5. Front Sway Bar upgrade with Polyurethane Bushings
6. Cusco Tower Strut Bar
7. Third Cat and Resonator Delete (check your local inspection rules).
8. Supra TT Big Brake Kit
I've done more mods than those listed, and I'm sure other members will have different opinions- as many have done more and many have done less. Just a few for you to consider, off the bat.
This is a perfect list. Thanks ShawnOK.
A lot of the posts seemed to favor the injen air intake. Is there a reason you chose Weapon?
No problem. Glad I could help. I chose Weapon R due to price, slightly shorter in length at the curve which allowed me to keep the OEM scoop, and even included the Ram Air Kit.
