has anyone else attempted to build the measly little Buick 181/3.0L carbureted engines found in the FWD X-cars and A-cars in 1982-1985?
I'm saving up to buy a particular 1982 Oldsmobile Ciera 2 door, which is currently equipped with the LK9 engine....as far as my info on these engines go; I am interested in the posisbility of this build with the following steps after getting it to be drivable and running good
1) intake/head port matching and opening up air flow; maybe upgrade to 4bbl Q jet....
2) roller cam/lifter swap, not sure which cam yet, since i have a 2.66 stroke and a 3.8 bore to work around....
3) open up exhaust manifolds, or get as close to headers as possible
4) redo the timing on the ignition system, since its an ECM controlled distributor, it shouldnt be hard?
5) rejet the Dualjet carb, if i dont swap out the intake manifold/carb set up to flow more A/F
6) custom lightweight 181 LK9 pistons for more revving, deck the block for more compression, into 9.2:1 or so from 8.45:1 stock
7) if i should choose to, and can save up enough, or get a job by then, TA Street Eliminator heads (they flow enough to warrant a 4 barrel upgrade, theoretically?)
now..I have a friend who;s on Cardomain and another forum, he currently have done turbo set ups on the following engines, 3.0 LK9, Draw-Through turbo, with TBI modification, LG3 turbo in his DD, 2.8L chevy v6 with turbo, another LG3 type turbo, at the cheapest route, with quality (currently at $700-900 plus car cost)..he thinks the mods #1-5 described above would be enough to push me closer to 200 HP on NA, with pump gas (91 octane or so)...at higher revs, and be stock appearing...until i can acquire a draw-through turbo set up, since i happen to like the carb look lol.....opinions? (should i just do the TA heads on a LG3 SFI block and work around the whole intake/computer thing?)
