I'm going to build a motor this spring (or sooner) and I was wondering what the best set up (reasonable $) will be to run high 12's. I'm buying a stock 86-93 LX, so that it is light. I was thinking about nitrous also... thanx!

Ok....you said "Reasonable" and I would assume you want it as cheap as possiable with-out really cutting corners.

(providing traction traction devices have been addressed& you have a sound bottom end)

Option One: 125-150 shot of spray with 3.73 gears and slicks...

Option Two:

*GT-40P heads for your local Junk Yard
(of course I would recommend having a good valve job, and new vale springs, keepers, retainers.)

*Cobra intake or explorer intake...(from your local junk yard)

* 65-70mm throttle body and a 73-75 mm mass air flow sensor

* 24 pound injectors

* E-cam w/ 1.6 RR rockers ( Both used)

* 1 5/8 headers w/ 2.5 exhaust

*3.73-4.10 gears

*155 lpi or bigger fuel pump (if remaining EFI)

*Pullies

* and remove any unnecessary weight.

If you wanted to go carb....an Edelbrock Air-Gap RPM intake with a 600 cfm DP or a 650cfm vacuum secondary carb and dont forget a new fuel pump, regulator, and dist.


This is only one of the ways of accomplishing your goal on a very limited budget.
Good Luck
