I believe some of the sensors are in different positions between the two motors. If I recall correctly, I think the knock sensors are the biggest dilemma.

besides that I sould not encounter any bigger issues?

[rajiv1998]

dude y did u even bother. The differance is only like 40whp. Full exhaust and a tune could make that power. U shuda just kept the LS1 and modded it. All the bolt ons and a big H/C setup will get you near your goal

[99huggerz28]

well mu ls1 has over 10000k on it and no longer was feeling as good as it once was. Plus my ls1 was not aluimium boack it was cast iron , going ls2 will be a little litter and its going to be brand new without any miles . I guess I was looking to recreate my car and motor .

Why do you think you had an iron LS1 block? Had your motor been rebuilt/replaced/swapped out at some point?

[99huggerz28]

just buy looking at it .. it does not look anything like the new ls2 block. I figuerd it was cast iron.

[9t8z28]

How many miles did you have on it? Are you sure it was 10,000miles?

All factory LS1 blocks are aluminum, not cast iron.

[99huggerz28]

it has 112,000 miles on it not 10k sorry and i swear it was cast iron . it was my stock 99 z motor ..

[99huggerz28]

even if it was not iron it has 112,000 miles on it .. what would you rather have a 112,000 mile ls1 our a brand new out the box 400hp ls2 ? thats really the ?

[9t8z28]

it has 112,000 miles on it not 10k sorry and i swear it was cast iron . it was my stock 99 z motor ..

If it was stock, it definnitly was aluminum. It has either alot of corrosion on it or alot of oil and dirt.

[9t8z28]

Any way, sorry to have hijacked your thread!

[99huggerz28]

any one got some good ideas as far as getting the most out of the ls2? i was saving up for a supercharger but i just might add a small dry shot. have any of your had any ideas on this

[Corey1987]

put a magnet to the block and it will fall off bc its aluminum, but yeh, heads, cam, full exhaust and a shot of the laughin gas should get u near 500 atleast

[INIT2WIN]

just heads and the right cam will get you at the 500hp mark at the motor. what are you shooting for 500hp at the motor or 500hp at the rear wheels?

[67CamaroRSSS]

One of my friends got 497rwhp N/A on a conservative tune with a 402 in his 99 SS.

[bluefields88]

you might need a new rear end if you have the stock 10 bolt, what kind of tranny do you have?

[99huggerz28]

trannie is stock (auto) rear end stock and im looking to swap out rear end too but im looking for 500 at the wheels
