jdub396 Posted September 22, 2005 Report Share Posted September 22, 2005 Where do "they" (GM) come up with their engine codes - LS1, LS7 ext... Anyone know?!?!?! Quote Link to comment Share on other sites More sharing options...
XGMTech Posted September 22, 2005 Report Share Posted September 22, 2005 Don't know how they come up with RPO codes (Regular Production Option)... but if you noticed, quite often they recycle an old one from the past. There was an LS1 engine in the 60's and 00's, an LT5 engine in the 60's and 90's, a ZR1 Corvette in the 90's and a ZR1 S10 pickup suspension option in the 00's, to name a few...

Cheatin Chad Posted September 23, 2005 Report Share Posted September 23, 2005 I believe the S-10/Blazer option was coded: ZR2 Alot of it comes internally(inside jokes,hidden meanings,etc) and some is even randomly generated. The vast majority of GM part numbers are completely random. That's why replacements for the same parts can have drastically different part numbers.

tonman316 Posted September 23, 2005 Report Share Posted September 23, 2005 i would agree that they make something up that sounds good. You know like gt,vr4,ls1,911,gsx,x runner, gtz, hemi... (well) etc. Quote Link to comment Share on other sites More sharing options...
cwest94 Posted September 23, 2005 Report Share Posted September 23, 2005 I believe the S-10/Blazer option was coded: ZR2 <{POST_SNAPBACK}> Thats correct. I happen to own one of these, lucky me. Quote Link to comment Share on other sites More sharing options...

(well) etc. <{POST_SNAPBACK}> GT means: Grand Touring or Gran Turismo GTO= Grand touring Homologated or Gran turismo Omologato Hemi was coined for the hemispherical shape of the engines combustion chambers (BTW the new "HEMI" is really a hemi in the truest sense) Porsche actually trademarked any car name with a 1 in the middle. Peugeot has done the same with 0 in the middle. R/T = Road & Track AAR= All American Racers (AAR 'Cuda) SS=Super Sport in most cases Quote Link to comment Share on other sites More sharing options...
