Default Installed HX35w 12cm. Where is the shove in seat?

I have a 92 5sp so a 21cm exhaust housing stock. bought used hx35w 12cm. First off what bolt did anyone everyone use for lower left when switching to wastegated turbo. Second took a spin around block and I'm not feeling no shove in seat. Not even like my old 92 auto with 18cm. Any guesses.

I hate to repeat what you just said but I wont see any results until I turn my pump up more? I guess in the end no matter what mod you do the best one will be to get gauges cause you will need them regardless of what you do unless you leave it stock.

you're catching on... gotta have the fuel to feed the fire. add some fuel and do some tuning; you'll feel the difference

I agree with adding more fuel and turning the pump up. You may also need to replace the stock injectors to really see your truck come to life, but until you add guages you are playing with fire - no pun intended.

did you leave the bolt out of the lower left? IF so you probably have a boost leak. You should have faster spool up.

i have the 60mm upgrade, seemed to spool a little slower, but the truck runs better all the way around, lower egts, higher boost. i like the upgrade wheel, but i need a bigger turbo anyway so it's soon gonna hit the pike for a s300
