ls1 to ls2

[pewterz55]

im looking at buying an ls6 intake for my 99 ls1. im just curious of what else i will need for the swap and how difficult the swap will be. i found it on tech for a pretty decent price and wouldnt mind the extra couple hp. right now my car is bone stock so i know i will need block off plates and take off the egr and air

no one?????

well you can either buy the ls6 coolant cross over pipe (highly recommended) or trim the fins off the bottom of the ls6 for clearance.
i'd also buy a oil pressure sending unit just to have incase you break it..if not you return it...
id also convert to a ls6 valley cover while you are there...great time to do it and improved my oil consumption a ton.
clothespins ...you'll see why.

Shady milkman is right on track. Don't forget the tune option of deletting the EGR valve. I would also recommend a lid/ K&N Fipk, or the slp tunnel ram scoop. A bigger MAF w/ pluming would not hurt either.

Above is a write up on swapping intakes. Be sure to unhook the line from intake to the master cylinder. This will help to keep you from breaking the oil sending sensor. Its probably about a 2 hour job, maybe a little longer if its your first time. Leave the MAF alone too, there is absolutely no reason or benefit to changing it.

Ach 98-00 has a better cooling system.

if you have problems with boiling your coolant then yes i suppose you do. for most apps it doesnt matter anyway what coolant line you use...the only reason the crossover is there is to transfer/ prevent air from getting trapped in that area. In the high po apps and f/i i can see the need for them as it seems like people are leaning out #7..but that issue isnt really related to cooling as much as it is to air/fueling ...so the ls1 style is really just a bandaid for the real underlining problem.

well i was looking up intakes on ebay and found a the Fast lsxr 102mm. it say it fits ls1 ls2 and ls6. its only like $350. but from i read these dont fit? anybody have any experience with these?

[pewterz55]

or anybody have any experience with any other intakes besides the ls6 or the fast? seems like that sall people put on round here

There is a reason why that is what you see the majority of people putting on

For the most part..all of the lsx intakes are based off of the oem ls6 design for the cath. Port fast and bbk ...until the 102mm lsxr. The big differences come in the material. Fast uses a composite material..like oem...this leads to better cooling characteristics. Another big advantage is fast uses a 3 peice design....this allows for much better porting than the 1 peice designs.
