Sikky 350z/G35 LSX swap
Really looking forward to seeing numbers from this build and how it compares in both performance and cost. If possible can you find out the weight of the assembled block?
I already know what kind of numbers we're going to hit lol
It may be heavier, but at 800 wheel, who cares.

Honestly the cost is already WAAAAY cheaper than anything I could have expected. Of course, we're just starting and who knows what hitches we'll come acoss, but it will be well documented for all.
Mad props to SOHO Motorsports here in Charlotte, NC. The guys there bend over backwards to do the right thing for the customer, 100% of the time. I'll never go anywhere else, with any of my vehicles, as long as they exist.

lq9 is roughly the same weight as an assembled gen 1 small block chevy long block with aluminum heads, expect right around 480-500 pounds for the longblock.
My dream would be to drop in an LSX, preferably all aluminum,
and mate it with an EMCO sequential race trans. Maybe one day.

That shifter in the video above looks and sounds like A$$. I want something that makes my car more streetable, not less. This would be great for the track, but too much for the street IMO.

wonder how much fab work would ave to be done to get that to work.... although i hear the tr6060 trans is a bit longer so itd be interesting if somebody came out with a sequential shirter similar to ikeyas for this application
+1
Anything is possible, just maybe not practical.... the kits out there seem to be for the LS series exclusively. You should post in the LS forums to see if anyone has info if the mounting is the same.
mounting is exactly the same you might have hood clearance issues though as the truck engines have a much much taller intake, but if you can make it fit the truck intakes flow on par with aftermarket intakes, like i said its just a lot taller.
also im not sure on the engine management and what would be best for it, since the l92 has variable valve timing. i imagine the best bet would probably be to get the ecu out of the same car and just use hp tuners.

ls1 is starting to get rare its been what 8 years since it left production? by iron block do you mean the 5.3L lm7/l33/lm4/l59 or are you looking at 6.0L lq9/lq4? probably is going to be near impossible to find just a bare block but local junkyards should have tons of wrecked trucks with them. if your after the 5.3L then look into the smaller trucks. 6.0 can be found in the smaller or bigger trucks(and by smaller i mean like 1500 series and there suv counterparts they share a frame with.)
and honestly you will probably pay about the same pulling a engine from a truck yourself as it would cost to buy a bareblock from someone.

5.3 would work, i would just bore it to 5.7 specs. my block has a hairline crack in it so id want to swap all my built internals over to a new one. aluminum or iron, no care. but i wanna keep it 5.7 so i dont have to buy different sized pistons, and from my research, most ls1's cant be bored out much at all if theyre aluminum
Look for an LM4, L33, LH6, or LC9. They are GenIII and GenIV 5.3 aluminum blocks from trucks and SUVs. I think I saw an L33 the other day for $200. They are great budget blocks to work from. ERL prefers to use them as cores for their monster cube (454+ci) engines because of their strength (after a resleeve, of course). Punching one out to put your 5.7 rotating assembly is going to require a resleeve which brings the cost up significantly. After you find an LS1 or LS6 block and refresh it, you'll probably be looking about the same price but have a much stronger block with Darton sleeves.

Has anyone adapted their swap to purely run in speed density yet? I'm looking into this right now. The OEM GM pcm, for the ls2 at least, uses a blended SD/MAF system, but I'm finding the stock MAF hits it's ceiling around 500-525 g/s. Which is roughly 470HP, so anything beyond that and your clipping the MAF. Unless you replace it with a larger one whcih doesn't really make sense in my head when you can just delet it and reduce your intake restriction and simplify your tuning.
