Block guard or sleeves? 300whp

- Wed Jun 29, 2011 3:05 pm #261525 im sure its been answered before so take it easy on me. I have done research, but most of the stuff i want to click on is from turbod16.com and the site is not working for some reason. my goal 300whp with all supporting mods. s300, pistons/rods, injectors...list goes on. But the one thing im not sure on is the need for a block guard or sleeves.

I know tuning plays a huge part and i do plan on having a great tune.

So any advice you may have will be sweet. Thanks

Block guard will reinforce the top of the cylinders but at the same time retain heat near the head so there's the good and the bad. I've never personally used one but I'm not at 300+ whp either.
