What are you stepping up to?My big heavy junk runs low 10's...I have impressed many being it's nothing special. I'm happy with it however I know it's on borrowed time...lol....I have heard some blocks are capable of going high 9's but its a crap shoot....Yeah I have the on3 kit and love it...I'm a fabricator/machinist too...Fitment issues...dont care..lol. Go for the turbo kit to get your feet wet...Thats what I did now I'm stepping it up this winter...Go for it and have fun...If the block splits youll know what the limit was...
Get a internal balanced forged crank and main studs.... Keep the Mexican blockWell I thought about a forged crank and use the h beams. The supercharger puts tension and twisting on the crank. What's the worst case scenario. Split the block. I'm just seeing who has run a stock or Mexican block down low 10s or high 9s. The block has already proven itself to me. I would back of the boost on the street and turn it up at track. Of course I would have to dump a different map in. Everyone says the Turbo is funner and I'd like to dabble with the on3 kit. I'm a fabricator so fitment issues are no big deal. And I won't whine.
So your gonna rebuild it and turn up the boost till it spills/ splits?
VERY impressive, that is going to be my exact combo in my coupe. Was that auto or 5spd?
62-1 turbo or something else? Same question as above, how much boost and what fuel? I have a 60-1 I am installing, but stepping up the compressor wheel to a 62-1 is pretty easy fro the local turbo shop.
That is what my buddies suggestedMy combo was a 306 afr 185 heads trick flow stage 2 and a t-trim made 595 rwhp and it split block. I would not go through the trouble it sux it broke everything when it went. If you want to go with a turbo and you are between combos either save for a dart that is what I did witch I understand is not in everyones budget or go 351w. You can buy a nice 351w block for same money and have a nice combo that will hold 600 all day. Plus you have the extra cubes to spool up your turbo quicker its win win.
