  • Spec a Cheap Nitrous Motor......

    So I'm thinking that the 305 in the Monte just doesn't have what it takes, so I'm thinking of piecing together a cheap($2500ish) nitrous motor build.... I still have the small block out of my '71 GMC so I have a block, I just scored a Scat 4340 forged crank(3.48 stroke) off ebay for a song, so now I just need the rest of the internals, I'm thinking 6" 4340 H-beam rods and forged pistons.... As for heads I'm thinking a set of procomps, you can get a pair of aluminum ones fully assembled for around $600..... And I already have a NOS big shot system..... So if you were going to build a nitrous motor for under $2500 how would you do it??

    Put the big shot with little jets on the 305!

    I have an NOS system for the Explorer intake on my mustang $500 jy motor $400 NOS system 150 shot should be fun! To bad I am smart enough to know I don't know what I am doing and it is still in the closet. CL impulse buy

        I would put a wet system in my Mustang and pocket the rest of the money. A 175 shot would be more than enough for me...been eyeballing the Zex system....

          Did you not read the outsider's DW review on brand Z nitrous?

              is this motor supposed to live? I thought this car was getting the super hifi double throw down motor?



              if the su-fi motor is destined for this car, spray the 305 til it sees its "higher being"

                So is the '99 now stuck in two post lift Camaro? It is a step up from the jack stand one though.

                  Yes the Monte is getting the turbo motor, but I got to thinking, that as I do all the suspension and chassis work to the car I could through the 350 out of my GMC into it... I figure I'd beef it up a bit and just spray the crap out of it, that way I can use that motor to help dial in the suspension before putting the turbo motor in it.....

                      you must have metric tonnage of cash to dump 2500 in a temp motor. I would think the suspension would work different with the 2 different motors. just me i guess.

                        It's not really a temp motor than a motor that will make it's way into another car, I just want to build it as cheap as I can, I do have some parts that have been sitting around for years, so that will help, I have a block, a 4340 crank(just got), a Holley Strip Dominator intake, a 800 holley DP, and a head stud kit and a few other odds and ends....... As for heads and a cam I'm thinking these....

                        Heads....


                        Camshaft kit..... ( I may be able to source this cheaper locally..)


                        As for suspension setup, sure their will be tweaks, but it will get me to a certain point, mainly sorting out that the car launches straight...... It also give me time to adjust to the power levels and learn the characteristics of the car, before I go hog wild with the turbo motor...... I'm thinking like a 400hp motor naturally aspirated, and then working my way up to the 350 shot......

                            I agree.

                            leave the stuff alone..and that chassis hates snaps.
                            stay nice until turbo.


                            how bout routing for gauges, wiring to add and the suspension. 2500 could be gone in a hurry elsewhere.
