(08-12-2010, 07:04 AM)ForcedInduction(08-11-2010, 07:42 PM)stomis Is there a reason you cant reuse the stock pistons if the cylinders are within spec?No. But at the age/mileage of any of the IDI engines I'd be surprised if the ring lands are still within spec limits, especially on the 617.
Quote:Some sort of diesel or MB specific thing?A little 8:1 compression g@sser might get away with a ringjob at 200+k miles. Diesels make 300psi+ every compression stroke, upwards of 700psi at full boost. They are built much stronger than a typical g@s engine but at the same time they have to endure much more stress. 1970's/80's metallurgy can only last so long.
Got ya. I figured that much just wanted to be sure there wasnt some special condition I was missing specific to these motors.
I'm no half asser. If it needs pistons then I'll choke up the $1000 and get pistons believe me. I'd rather start off with a $300-$500 motor and spend from there than start with a $2500 motor and still have to spend like with a 4bt.
@ E300TSC- I would appreciate the pictures. I think I know what build your referring to. Its a later model red blazer which are a tad bit more cramped than the earlier model I'll be using. I also plan to switch to hydro boost brakes so I'll have no issues with booster clearance.
@ George3soccer - George thank you. I've been waiting for someone to outright say my number goal is obtainable with the 617. I'd rather go with it to gain more engine compartment space. I've been reading through alot of the dyno sheets so I'll keep digging through. Thanks
Thank you all for the input its a huge help. I have a line on a 250k 617 and trans in my area for $400. Guy said he pulled it running great.
