Hi Guys,

I got a friend here who has a subaru brz

Current mods:

- Kraftwerks c30-94 supercharger kit
- agency power headers
- tomei overpipe
- tomei 3 inch titanium catless front pipe
- tomei 3 inch titanium catback
- tomioka water and alternator pulley
- cusco catch can
- clutchmasters fx350 with lightweight flywheel
- driveshaft shop aluminum driveshaft + axles

his car is runing great, has been supercharged for a year now, going to dyno it again the next couple of days.

last dyno was last year without the clutchmasters and driveshaft shop upgrades and he had a agency power frontpipe + over pipe combo that was 2.5inch catted and it got him around 270 whp on 98 ron (around 93oct)

now he wants more power and wants some recommendations.

- should he go with the smaller pulley for more boost or should he go c38 upgrade?
- which injectors, fuel pump, pictons, rods, etc do you guys recommend to use?
- if he goes c38 upgrade, do you guys recommend him going with the hks stroker 2.1l kit with cams or should he just get a piston/rod set up?
- what do you think are the most numbers he can get as he does want to reach over 430whp ~ 450whp (if possible 500whp even though he doubts it) , not to forget the best fuel available here is 93oct.

Awaiting your feedback guys

Thanks in advance.
