Slowpoke-thanx bro, i am rather cool lol.....I'm looking fowad to thi mini-car debate cause u seem like a guy who knows his shiiiz, & i can appreciate that.

The equation LS>3800 is incomplete, silly even w/o acknowledging the desired goal, (mine is a lightweight, reliable, descrite, affordable, sleeper that can run in the 10s, and is relatively docile on the street to be moderatly daily driven.) My philosophy is enough is cool but too much isnt cool.

lsx's Canidacy:
1. The LSX platforms generally dominates as a result of cubes, but to stave off a turbo Series II or Lc2 in a 2500lb car you gotta throw boost at the truck motors or n2o @ the pass car versions. A 800hp motor would also need adequate trans, rear axle, fuel system & suspension. Bench racin a turbo lsx in a 2500lb car is cool but actually cutting a good 60ft is different.
2. even my lil sis knows that a mazda or datsun aint supposted to sound like a vette, so i doubt ill rope any1 into a race 4 cash (We bet out in philly)

Boosted 6 bolt main 3.8: Accomodating, adequate but not excessive.
The series II & III acomplishes all the above, even some of the goals the lsx cant. For pennies I'll build a series III. l67 or l32 block, fbody intake manifolds, modded fbody exhaust manifolds w/a 4l60e from a fbody. With traction, a decent stall, nissans r200 rear, moderate sized turbo(PT6776 ??), injectors, Walbro 340 gpl Fuel pump, intercooler, Cam, 1.9 rocker, ls6 valve springs & racegas I'm @ my 10s goal(eg Darkhorizons sinfully fast feiro). Remember I technically dont need to run a 9.3 @ 150mph, i jus need to be across the finish line b4 da cat next to me.

Grand National, where boosted 3.8 made a mark.
If you check the dates im sure you will see that when mike/misred built this 3.8 rx7 it was yrs ago, prolly b4 ppl were throwin flipped manis & slappin turbos on lsxs. I have a friend w/ a 99 ws6, another friend w/ a terminator cobra & i have a turbo regal. While the larger displacement lsx does have more max hp potential, it will in no way make more torque than the lc2/grand nat motor w/ the same minimal amount invested($5-600).
