I've always wanted to do that, just hammer a jy motor till it begs for mercy., I just don't have the time to change one out after every weekend. Guys used to do it the old 5.0's back in the day.

 

What body style car is it going in? With the parts listed you busted your 4k limit. If you could find the intake, heads, and short block used you might make it.

The valve train needed to make 500 NA will cost 1200-1800 new.

Cam -300-500
Rockers 200-(stock) 400 rebuilt stockers
Springs 180-400
Lifters 300-600
Pushrods 100-200
Timing Chain set 100-200

It adds up fast. You could do a stock or yard N20 build. If the tune is good you'll be close with a 150-200 shot. If the tune is bad (Boom) goes the short block.

Then you'll also need the draivtrain to handle the power, even on street tires.

Good Luck

 

3/4 race cam fosho would be matched great with fairy dust and that stage 2 chip..haha but seriously 500wrhp aint cheap, if it was, everybody would have it!!

 

What about the JY engine guys throwing turbos in. Most have around 4K in it. check out denmah, even though not all of his stuff is up to par, such as how he lost a axle when a c clip popped. His motors seem tough to beat.

 

Yes I am new here and I wanted to put this motor into my 1998 Camaro. I was expecting to get the 500+ rwhp with the turbo and bore.

 

for 500rwhp turbo no need for a 408 kit, no need for the intake, no need for the L92 heads.

Your first post sounded like you wanted 500rwhp NA now for $4k and then a turbo later.

Still though the budget is tight even just to hang a turbo on an otherwise stock engine.

 

How about a "Done It" share?

Used 134 meticulously serviced LQ4, used yet done set of 862s with springs that matched a Comp .629 lift cam. Stock bottom end, Eddy LS1 RPM intake, used AED100HO carb. Heads and cam were $1250, engine was $100, intake was cost $700 new, carb was $300 but was bolt and go. In a 78 Malibu, 3500 stall, 4.10 12 bolt, 275 60 Mickeys.

11.34@119.5. HP calculator with a 3350 pound raceweight said 520RWHP, 603 flywheel HP. LSX seems to be too easy. Havent went injection yet, and have since killed it with a 200 shot of spray, I just upgraded to a 402 stroker, same ported heads, slight bigger cam, 6010 ignition box, and a Super Victor intake. Hoping to be high 9s pretty soon, then a 250 shot of N2O.

 

Bolt ons with nitrous or build a rearmount. If you do it right both can get you what you want

 

Try searching the classifieds for these items:
ported heads (I'm assuming you currently have an ls1, so cathedral only)
fast intake
pacesetter headers
tsp duals
unnecessarily large cam
gaskets and head/rod bolts (you'll need them for the rpm it'll be running at)
+ some tuning

I estimate that's around $3550.

Getting 500rwhp isn't the hard part; getting a reliable and streetable 500rwhp is.
Built trans/driveshaft/rear, converter, drag radials, and probably some suspension would be needed to handle and utilize that kind of power.

If you wanted a streetable 500rwhp, try a ported AFR/FAST combo as opposed to ported stock heads and stock fast. The sweet spot of ls3 heads seems to be in the 445/465rwhp range on 6.0's. You could obtain your goal with them anyway, but at the cost of low end power. Same with the stock ported heads/ stock fast option.

 

The engine can be built for 4k and make 500 at the wheels...or very close to it. However, supporting mods to handle the power will break you.

 

I know...I've got around 10k in mine

 

Nice job. I like those old bu's last of the full frame cars.

 

Yea if you can do the fab work needed for the turbo. Other wise it gets $$

 

Can you please share the HP calculator you are using? IMO it is wildly optimistic. Would love to plug my 4200lbs car into it or a friend's 3800lbs 10.9 at 122mph into it(425 on the chassis dyno), and they are just heads/cam, hydraulic, ported stock casting LT1 turds.

Most of us wont fine a good LQ4 for $100 either. Around here a burned one is $500+

 

Realistically, any combo of CNC heads, decent size 236-240 ish cam with over 600 lift...fast 90mm intake, longtube headers...and a nice 3" free flowing exhaust... Will get you 450-480 on any dynojet In The country

Then just add an ati damper and a moroso vacuum pump and you will be over 500 to the wheels....

Now....500 to the motor, is pretty easy... Cam only and an intake gets you there

 

I meant to type $1000, not $100. I did however just buy an aluminum 5.3 off Need2Speed for $100, but is was just a shortblock. But after dissasembling it, it is mint. Fire sale, never find another.

http://www.dragtimes.com/horsepower-...alculator.php?

Never dynoed either of my Malibus in thier current setups, but the calculator is pretty fun too play with.

 

That gave a result of 450FWhp for your car and 528FWHP for my heads/cam LT1.

Far as aluminum 5.3s did you get a FWD one? Those sell cheaper because they are a PITA to use.

 

The first thing that comes into people's mind when someone says 500RWHP and $4000, most will say hell no, aint going to happen! But reality, its Subjective!

We can tell you what parts combo will do it and what it would cost retail, but that isnt always the case.

People find rare buys, have buddies to give them stuff, and people don't mind used parts or how long the final product will last.

It can be done for $4,000, but it will take either one hell of a bargain shopper or sacrafice realiabilty to stay cheap or a combination of both.

OP, for 500RWHP, you need killer heads, big cam, Nitrous

 

I assumre it was front wheel by the bigass hole cast into the oil pan. Once I got the pan off it seems to be just another LS, but I haven't looked at motor mount bosses or much else externlly. But hey, the block is worth $100 just for scrap.

My car? Screwed the pooch. The car is 3350 without my 325 6'7" frame in it.

 

Looks like another ls...but it's way different.

The block and crank are shorter, the bell housing bolt pattern is for The metric trans, the motor mounts are in different spots...etc.

PITA is an understatement...
