I would say that fuel rail hooks up the same i duno havn't got one yet it sounds cheaper to buy katech's spacer and go with your ls1 rail so ya dont have to buy the ls2 harness for 100 and buy a ls2 fuel rail unless ya already got one....the ls2 runners on the intake are taller thats why ya need the ls2 rail or space them or ive herd of ppl bending there ls1 rail and getting it to work but if you bent it wouldn't ya think it would draw the rails closer to each other when ya think about it

for all that song and dance... a fast sounds more attractive.

If it was a direct swap i could see doing it, but after all the other stuff you might as well go ls6 or aftermarket.

ya its alot of diff stuff to make it work but if it makes me as much power as a fast if i get it port epoxy and i only got 400 in all of that im ahead of the game......going to have to buy a 90mm tb anyways with ls2 or a fast

whats the difference between ls1 and ls2 injectors?

1999FirehawkLS1

iTrader: (21)

I guess the o ring seals are diff and the wire connector is diff

02ssbluethunder

do you think my ls1 injectors will work in the ls2 intake. they seem to fit okay but i won't know untill I put it on the car to see if it leaks fuel or air. Can they be refitted with new o rings

1999FirehawkLS1

iTrader: (21)

should be able to use them juust might have to get the o rings from katech click on the link i posted a few post back they got them .

have u put the tintake on the car yet w a tb and have u had any problem w the tb hitting the water pump (assuming your putting this on your ls1 motor)

pics would be nice!!!

I'm not arguing this, only posting info. Check out this link and read graph #4, the LS2 intake vs LS6 intake on an LS2 engine.

I think you guys mean MAP not MAF Manifold Absolute Pressure sensor thats on the intake its self the MAF Mass Air Flow sensor is the one thats in front of the TB after the lid.

What the OP mainly concern is how it works on a 5.7L LS1 engine. The 6.0L LS2 engine will be a different measure. I'm kinda on the same boat as the OP. I really wanna know how it work out.

you can get a fast 90 for around 500 used. A lot less hassle. Plus after you buy the intake and the little stuff you need for the swap, get it ported etc., your going to be spending about the same.

I will have under 500 and never seen one for that cheap used anyways
and herd that fast can burn up #7 cyc

ls2 intake $100 new
Port work $275
Holley 90mm TB w cable hold brackets 379.00 (going to have to buy 90mm tb no matter what...)
swap stuff to make it work $50 w useing fuel rail spacer
going to have to buy injectors no matter what...

$425 total

you dont have to buy injectors with a fast. I got mine with a throttle body for 750 on the classifieds here. I think your math is a little off too, 50 bucks for everything to do the swap? One of pieces you listed was 70 by itself.
