Anyone done the Ls1 to Ls6 conversion?

I'm running just a set of ported stage 1 LS1 heads with stock size valves and good double springs, cam, and all of the bolt-ons. Haven't dynoed but the mph to hp calculators say that it takes well over 400 hp at the wheels to pull 118 traps.

Re: Anyone done the Ls1 to Ls6 conversion?
If you do the LS6 head,cam & intake package with no tuning you get 400hp at the crank right? So if you do the LS6 package plus the SLP 400hp package wich is Cai,Maf,1.8rockers,Headers,catback,diablo 2 programer and K & N filter what do you get 500hp or something?
Re: Anyone done the Ls1 to Ls6 conversion?
Not quite. ....Don't we all wish advertised HP mods would stack... Its like this: Stock equipment has to meet regulations so thats why its so restrictive. If you did the ls6 swap with stock exhaust and intake with no computer tune, other than people calling you stupid, you wouldnt get close to the advertised HP increase. or maybe i've been drinking too much tonight. idk.
Re: Anyone done the Ls1 to Ls6 conversion?
Ghost are you sure that doing the head and cam and intake package with stock equipment would not get you the advertised HP?I think you might.I am probly wrong though.
Re: Anyone done the Ls1 to Ls6 conversion?
Problem is I live in Japan and I want a 500hp ls1 but good tuning is out of the question here so I have to live with what i can buy of the net that is why these kits seem like a good idea and this is for my daily driver.

The cam is a custom grind 228-236 .614-.603 112 LSA ground 2° advanced. The lift numbers are with 1.75 roller rockers. It would be .598-.588 with 1.7s.

yeah....good luck with that!
the SLP kit is not a bad kit, but the only things that are really doing you any good are the rockers, headers, catback and the Lid (you don't list it but i'm pretty sure it's included). the CAI is not really gonna gain you much, nor with the maf sensor. and the programming of the diablo isn't bad, but for 1/2 the price you can mailorder a much better tune.
the power numbers we were talking about earlier in the thread....the final gains from the LS6 kit....were assuming you were running must of the parts that come in the SLP kit you mention.
i'll try to lump it all together:
lid
LS6 intake
LT or midlenght headers and Ypipe
catback
figure about 340rwhp from this round of mods. all for about $1500 give or take depending on the header style and catback you choose.
LS6 camshaft
stock LS6 heads
with a decent mailorder tune from madwolf or similar you should probably put down 375hp to the wheels, which is about 425hp at the engine.
the rockers will probably gain you about 10-15hp on top of that.
now if you want an honest to goodness 500hp car....it's gonna affect how well it performs as a daily driver.
to achieve that...assuming you mean flywheel...you're gonna have to be making 430-440hp at the wheels. which means a pretty decent size camshaft and a good set of heads, along with a good tune.
something in the lines of the F14 cam from Futral and a set of ported heads should get you there without too much problem. the cam alone is good for a solid 400rwhp and most heads shouldn't have a problem adding the extra 30hp on top of that.
sounds like you really need to sit back and assess your goals, do some more research and start planning out your attack plan.
speed and power take money...how fast do you wanna go?
remember, once you start making those power levels...things like clutches, transmissions and rear axles start to break....and that's not cheap!!!

Re: Anyone done the Ls1 to Ls6 conversion?
A good idea is to de-screen the MAF though. I did that and it really increases my throttle response. But there are a few places that do mail-order PCM exchanges. You could email them or call them on the phone to discuss your future upgrade plans and see what they thing you should do. They know LS1 mods really well, so they would actually be a great place to start. Plus they deal with thousands of LS1's so they know all about what mods yeild how much HP and what tuning they require.

Why do you keep saying that? What makes you think that a mailorder tune is better than a Predator tune that was designed for the package?
You keep dissing Predators. Have you ever had one?? If not then quit.
If you've had a Predator and the tune sucked then dis away.
For the results of a Predator custom tune check sig.

Re: Anyone done the Ls1 to Ls6 conversion?
relax al...
i wasn't aware they did custom tunes for h/c combos. my bad.
but still...for $100 lower price you can have a similar tune by mailorder.
$250 for a custom tune or $400 for a custom tune....not sure which one i would choose

Well let's see $250 mailorder tune, what does it do after the tune.............................................. ..................hummm nothing.
Predator $400 custom tune, what does it do after the tune..........................................humm mm oh yeah it is a live scan tool, it reads and resets DTCs, it allows you to touch up your tune with WOT timing and fuel changes, and you can still change settings for gears, tires, shift points, rev limiters, ect without exchanging computers yet again.
