Haven't confirmed yet but its either a busted piston or broke ring in my 05 :/. Had intentions of building it more so guess we will roll with that idea. Current setup is Advanced induction 226cc ported heads BTR valve springs with titanium retainers, Lunati trend hardened one piece pushrods, lunati custom grind cam (227/236 114) LS7 lifters and tray. Kooks headers to stock exhaust straight thru magnaflow xpipe. Ls6 motor

What brand rods/pistons is most people going with? Not sure of what power I'm shooting for. Has stock 6sp with ls7 clutch. Want reliable power. Isn't a dd so to speak but sees street driving only. So I'm uncertain whether to run forged or cast internals. Inputs?

If the piston damaged the cylinder you'll have to get another block anyhow, so that will be your determining factor. Another board member built a 383 shortblock for about $2500 (they are about $2k+ more mail order). A forged shortblock is a great foundation for suture builds whether stock displacement or a stroker.

Sounds like a good excuse to go all out to me.

You need to find out whats salvagable from the current motor and what your end goal is really before you can make decisions.

So your car used to be my car. Let me know if I can help!

The cam is a 227/235 btw.

MrAkalin

This, is what makes me spend all my money.

Anyhow, having built a few cars, I suggest most importantly setting a budget, obtaining an end goal, determine what you're going to reuse, then search/ask for help

Yea Andrew it was ur car lol.

Lil update. Started tearing the motor apart today, see exactly what happened. No apparent bent pushrods or broke springs, all spark plugs was good, no broken tips. The intake is full of oil along with the air intake. Hopefully its what I believe it is with no further damage. Went to compression test it, and my kit is for diesels only with no spark plug adapters so I'm going to grab some tomorrow after work.

As for what I'm going for, I honestly couldn't tell ya. I come from the diesel scene, dmax particularly, and started them projects with no end in sight. Made some solid 945hp pulls and wanted more, before questioning what the heck it was I was trying to accomplish. Long story short I sold the motor and driveline out of y truck and threw it back to a stock studded motor I built, and bought this car with the money as lsx motors are 1/4 of the prices on parts, some even more. Car ran decent with current setup, not near as fast as my truck ran, but I definitely want more power. Just got to get up to date on the ls scene info and what works/doesn't work for my intentions.

MrAkalin

Ok, well if you don't have a power goal. Do you have a budget set, and decided if you want boost, spray, it stay n/a?

05maroonv

No funny gas for me, nvr been a fan of it. Made the power I did in my dmax on fuel only. I'm a boost junky. Been looking since I bought the car at chargers etc but haven't stumbled upon a good site for them. No real money budget, but not looking to blow away money like I did in different turbo setups, fuel setups etc like I did on my previous build. Not sure what would be the best route to go honestly, like I said I'm ls illiterate at the moment. I've built small block old gassers and diesel motors, but that's it.

I dnt even wanna now the price on that kit. Hell regular superchargers are pretty high for wat they are. Ideally I believe I'd want around 550 or so. Just got to see what I'm working with tomorrow and how I'm gonna accomplish making more power. Want it reliable so that if I wanna drive across state it wouldn't be an issue.

05maroonv

Lil update. Finished tearing the motor down today after work. Busted a good chunk out of one piston. Head may be salvageable, valves/seats wasn't beat but the busted cylinder pitted the head surface some, have to see what the machine shop says on it....

So on motor options, what kind of prices are we looking at? Lunati pushrods etc are all fine, cam is iffy, debri from the piston is in the crank case not sure if it could pick it up. Is there anyway to make 550-600 on motor only no nx/boost? Or is it impossible. I'm going to make some calls tomorrow and find out some info

In NA form, these motors start hitting a ceiling around 450-460rwhp. Depends on dyno of course.

MrAkalin

I don't see it being done without a larger displacement

ryridesmotox

Of course... But the question is, are you going to like driving it with the cam you would need to spec for it to get that kind of power. And are you going to like replacing valve springs every year.

05maroonv

What would be the best setup as far as daily driver but most output? Looked at 383 kits etc but not sure what would be best with my heads etc. didn't have time to call around today and talk to people who are ls literate, all new to me as to what crosses over etc

itsslow98

550-600rwhp n/a is 427ci+ territory if you want it to be daily driveable.

ryridesmotox

If you want 500-600 just go supercharged or nitrous. Unless you want to swap a new motor in. Staying N/A is noble and **** but its not easy in high HP applications.

I have seen an ls6 c5 383 make 520 whp with a big cam and 11:1 compression. He didn't daily drive it, but he drove it on the street a lot. Would not be the funnest thing to drive in traffic I'm sure.

I wouldn't go any larger than a 408 with those heads. Your head/cam combo on a decent 408 should net you 475-500+rwhp. Not quite what you're looking for, but would still be an excellent power plant N/A.
