ok thinking about coupling my 87 iroc-z with a 3rd gen trans am gta. can you guys tell me what you know as what is the best year hp ratings trq ratings aaliable engines etc etc etc my iroc is almost mint and i paid 1600 hundred for it exactly what i plan on paying for a gta or simaliar

 

Best year for HP were the 91-92 model GTA's. 92's put out about 240 Horse at 340 ft lbs of torque. For further info, be sure to look into

www.gtasourcepage.com

 

I also should have added, 92 GTA's are very hard to come by - if I remember correctly, they only made 508 of them.

 

90-92 L98s were all rated at 245 HP and 345 Ft/Lbs. Z28s, T/As, and GTAs got them.

 

BTW, it may be a bit hard to find a mint 91/92 GTA for $1,600. Good luck though! Here's a layout of all the engine specs if you decide to go with another year.

i should have mentioned this but i hate those models they changed the nose on it i dont like them at all the other model is what im looking for with the wrap around wing

 

So, anywhere from an 87 to 90. The specs for those GTA models as well can be found at the above link.
