So ive been builing my motor for 2 years, bottom up from scratch. just finished it last month and droped it in my 91 DA .
msd 6al 2step , breather tank , Stock gsr head with S2 cams, S2 IM, flat valves, valve train, str fuel rail/cam gears, FPR, 310 injectors. walbro 255 fuel pump, 100 shot direct port. Arp headstuds/ rod bolts. 82mm gsr block / 82mm gsr pistons with ls crank/ rods. 8.5lb FLW , hot tanked polished balanced. hytech tri-y's ,e cut out. tuned on 91 and hondata s200 . making 190hp 136tq N/A 350 with nos. still needs to get retuned.
what do i do next to make more power?? i was thinking itb's or 70mm TB with bored out and port matched IM. on a $1000 limit .any sugestions? Maybe high compression pistons? boost? ooh and this is my daily car

 

I dont even know what to tell you.

 

I would recommend not running ITBs on a daily driver. They make great power and throttle response is amazing, but they are finicky and need constant adjustments. Get your Intake manifold extrude honed and port matched to your cylinder head. If you don't have an ITR Throttle body, pick one up and send it to RC Engineering for big bore work. Or you can just pick up a Spoon ITR Throttle body. To boost properly would be above your $1000 mark.
