## Questions & Answers

**Q: Will it work for a four runner 2001 Toyota V6 motor**
A: probably long as its a fuel injected engine since this is a universal kit.

**Q: Will my 2006 acura tl with 130k miles handle 100 shot?**
A: most stock internal combustion engines can handle extra power. stock blocks can usually handle and excessively higher amount than other components like the connecting rods. for my engine it makes 200 chp stock and the block can handle well over double that, BUT the connecting rods can only handle 275 HP of torque shock before they will be prone to failure

**Q: will my stock pistons and rods stand the 150 shot  ? I have a stock 2009 g8 gt pontiac**
A: the rods will handle it all day. I've had 2 g8 gt's just make sure you pull a cpl degrees and check ur fuel enrichment. go get a wideband 02 sensor if u plan on running it long term

**Q: Where is nozzle installed on supercharged application? is it like na cars, after maf but before throttle body?**
A: Before the maf it means do nat spray nitrous and fuel to the maf will trowel off your maf tables
