Lt 1 Engine ?

[SMOKEY818]

I Was Planning To Put A Lt1 Into My 89 Camaro, Is There Different Types Of Lt1 , Do They Change In Any Years. If So Which Year Should I Get.

93 is the only real different year it doesn't have a MAF sensor. Other than that the the engines are all the same. I think 93 has a ob1 computer. 94-97 have the obII.

I thought 95 was OBD II, but I could be wrong.

[SMOKEY818]

Which One Is The One I Should Get,i Heard That One Of Those Obd Ii Or The Other Is A Pain In The Ass To Get The Trouble Codes Or Something Like That?

Your most likely better off with a newer one. Sometimes it takes a couple years to get all the bugs worked out.

OBD II started in 97...

[ridge_runner]

if you got the extra cash try getting a wrecked 98 or newer camaro... and do an ls1 swap... i think im gonna start saving soon to do that in my 84

[Chevyracincamaro]

word. hey ridge, while youre at it can you save a little extra an do my car...

[ridge_runner]

yea i can save ya a few bucks

1993- Speed Density OBD I
1994- MAF OBD I
1995- MAF OBD I, Vented Opti, CA cars had dual cats (still OBD I)
1996- MAF OBD II, More sensors, NO MORE HARDENED PUSH RODS
1997=1996

Tuning software is cheaper and easier on the OBD I cars. There are some extra things that sometimes get in the way of new mods on OBD II. Some people actually pick up 10hp converting from OBD II to OBD I because some of the computer controls are not in the OBD I that affect the OBD II cars. I am not familiar with OBD II tuning, so I cannot tell you exactly what the differences are.

93's are the fastest

93's take to fuel mods a little better due to the speed density but its not really enough to make that big of a difference. The main difference is the electronics/CPU of the different year engines.

[Dober89]

I thought speed density was less forgiving to performance mods and needed to be recalibrated when you do a bunch of mods. To me it seems like 1995 would be the best because it has the hardened pushrods and the vented opti spark.

[Deadcarny]

1995 Is generally considered the best year to get. I know when I was shopping for mine I would only get a 1995.

[89IROC&RS]

well, the key thing to me with the LT1 is the opticrap ignition, there is a second design, i think its listed as the vented optispark, those tend to go bad less often, the first design was pure shit. just my two cents.

i'd go with speed density for the fact that it's cheaper to replace a MAP sensor than a MAF sensor.

is it possible to bolt L98 heads to an LT1 and use the intake, dist, and fuel system?
