Frankenstein Rod/Piston (Evo or 2G) Results?

laser_raiser · Jul 4, 2012

Hi everyone,

I'm looking to do a rebuild and crazy blueprint of my next engine. I'm inspired by Ostar's 749awhp stock block and would like to work with similar results on a reasonable budget (but using DSMLink, and more economically priced stuff, and not necessarily stock)

I'm considering possibly running stock Forged Evo pistons which requires modification of 6 bolt rods (probably end up purchasing from DSMgraveyard.) I just can't seem to find much for experiences with people using them.

I really want to get the geometry and mechanics of everything spot on, and I'm not sure if these modifications would help at high horse power or not? The only thing I found is that someone with EVO9 pistons think they broke wrist pin after 1000miles which is not a good sign, but could have been an assembly issue.

Thanks

IF you want something with 500+ horse power that is somewhat reliable than you just need to spend the money on a good set of forged internals and not try to be cheap. Yes they have had great success with that 6 bolt, but they have blown a few up in the process. That thing is living on the edge of destruction every pass it makes down the track.

I'm also looking at frankenstein block options, and what people have had most success with.

i recomend 2g pistons on 1g rods with arp bolts that is the setup i an goin with its good for 500hp +

Does anyone know of any threads with people's experience running these setups? Modded rods are in theory weaker and puts in machining tolerance errors that could be a weak spot that breaks with high hp.

They aren't many... 90% of people never get a chance to make that much power before the car is sold or parted out. I know of one guy using 6 bolt rods and evo pistons making over 500.

This is just my opinion but your better off spending a couple hundred more and getting a set of forge rods and pistons. I mean why spend 500 on a set of 2g piston on 1g rod. When you can get some thing better. If you really insist on doing it, your better off taking it to a local machine shop and have them machine the rods to fit the piston.

I'd like to get a build capable of 600-800awhp+. Apparently 749 is possibly on OEM rebuild, but what's the next weakest part, and how long until it fails? (stock wrist pins? then what?) I've read that forged is only really needed to handle the sudden torque produced from hitting high boost suddenly.

I'm trying to get a good picture of what the weak components are and get a high potential hp build, while only upgrading the weak or less durable parts to prevent massive failures. I don't want to upgrade parts unnecessarily if I don't need to, which would save $$ for other upgrades, and help develop a picture of what components are adding actual gains that I expect to use.

For that much power to be reliable you need forged internals. Yes 749 has been made on stock internals, but for how long will the stock internals handle that. You don't need to worry about saving money and being cheap if you are trying to make that much power. 700 buck for rods and pistons is a very small amount of money compared to what you will spend on the turbo, fuel system, transmission, transfer case, and suspension.

Don't buy from dsmgraveyard you should read their feedback is horrible.
