what are the differences between 94-01 LS and the pre 94 models...i figure there must be a diff, is it something like a knock sensor or something small like that or is the difference as great as for example...93 tranni wont fit on 94 block...i want to get a ls and i see like 91's for like 400-500 and i see 97's for like 750-850(excluding transmissions) which should i go with...besides the fact that ones obdI and the other is obdII , and ones like half the price than the other are there any other differences?

 

well they are the same except the 91 might have 200K miles and the 97 might have 80k miles. Thats the difference old and new.

 

couple ponnies difference...more miles with 90-93 motors most likely..the 90-91 motors are obd0 by the way and 92-95 are obd1 and so on...just to let u know!

 

90-93 130hp 124tq
94-2001 142hp same tq
90-93 cable trans
94-2001 hydralic trans thats the big differences i can think of..

 

90-91 is 130 @ 6000 RPM / 121 lbs-ft
92-93 is 140 @ 6300 RPM / 126 lbs-ft

The B18B motors have a little more power due to the intake manifold. Longblocks are the same otherwise.

That's mainly because of the YS1 LS tranny gear ratios (vs. the A1 tranny gear ratios) and OBD-0 vs. OBD-1 electronics.

 

I would hafta disagree with you newman. Maybe the gearing is slightly different and of course yes, the obd difference. But the <U>major</U> factor of the ~10hp is the cams. the 92-93 are definetly larger.

90-91 = 130hp obd0
92-95= 140 hp obd 1

all in all they are pretty much the same speed

 

Newman said it was the tranny, I just stated the #s

 

i corrected it, sorry hhogan

 

Well, G3's are heavier than G2's, but the ten extra ponies might just even it out....Theyre almost identical...

 

90-91 cable trans

92-00 hydro...

I need a cable tranny, ef swap...duh
