A complete LD9 build??

montana_GX · 05-07-2007, 04:10 PM

I was over at a friend's house on cinco de mayo and he was showing me his bike in his shop. As i was looking around i noticed a 97 acheiva sitting in the corner. He said it was a car he was doing a engine replacement on. Well long story short he's letting me have the old LD9 out of it and put it on a stand in his shop. So i have officially begun my 2.4 Build for my car. I'm gonna try to take a ton of pics of every step. We're gonna strip this thing down to nothing and build it back so it can handle boost and maybe even some Nitrous stages. Nothing track worthy like some of the beautys i've seen on here, but once i'm done it'll be the baddest olds around my town. Pics soon to follow.

what's your plans? Like what do you plan to throw into the motor to make it sout? Just curious.

Don't exactly know entirely. Gonna start by tearing it down and have the cylinders bored. New pistons/rods/springs/valves and everything. After the bottom end is done i'll rework the head, hopefully get some "secret cams" that i've been hearing about. Past that we'll see, can't decide if i'm gonna go supercharger or straight boost. any recomendations at this point are appreciated.

Oh, and spyhunter, just want you to know that the grand am is now another one of my inspiriations.....NICE WORK!!!!!!

You're on the right track with forged pistons and rods and a ported head with larger valves and stiffer springs. If you're going all out on the engine, you might be better off getting custom ground cams instead of just using the secret cams. No doubt they'll work pretty well, but a custom set ground to your specifications will work better. And I vote turbo...or "straight boost" as you call it. No sense wasting a fully built engine on the GM supercharger and only pushing a max of 250hp.

ya, i'd like to go turbo. the only issue was price and ease of install, however i now figure if i'm doing all this other stuff i might as well have the best results i can for the work. any suggestions on turbos or packages?
