Hey guys I am currently building a 3rd gen 3s engine and my only concern is the block cracking problem my Block is a 3s 1996 block it is the thicker reinforced block.
I am aiming for big HP (850WHP), but this block roumors are getting abit to old everyone says different thing about it use sleeves dont use sleeves use Hardblok dont use it, leave the bore standard... alot of mislead info Can anyone out there share with me what I should be doing with my block should I sleeve it or not the bore I am going for is 86.5mm I have had someone tell me its not safe to go above 650 with this bore this person uses sleeves and has no probs but I have other freinds stating that the sleeve will still crack so basically I dont know who to belive . I have spent thousands on parts I dont want it all to go to ****s after all this money spent only weak spot i found is this block issue so please anyone out there running big hp on a 3S share with me what I need to do. Also I would like to use the 3s block I dont wanna use the 5s!!! --------------------  |

Our heads are the real first limiting factor (for an extreme hp goal). And as Art (lagos) mentioned a 98+ 5s block is the best for this swap.
If you are not a member of mr2oc for this power goal… you're wrong. Also with 850whp…. you need to go AWD. I spin a ridiculous amount at a little over 300 lol, you will just sit there and spin wheels at 120mph if you aren't. I have a pretty good thread on mr2oc (link here) that has a TON of info for going up to about 600 (which is already ridiculous) read through that. Info on 5sgte builds, e85 conversions, ect.
