ferrarit

Just got a 98 ls1

stats as I was told:

425 Hp (at flywheel?)
GM Alum cylinder Heads (later casting) - ported / shaved about 7 thousandths with machined valve guides.
LSM 226/230 camshaft
Manley Dual valve springs
ferrea stainless valves
cloyes timing chain and gear set
fly cut pistons
NGK tr6 plugs
cometic head gaskets
etc,etc

Does not have an intake as of now ...

mileage:
1500 on the upper
100k on the lower

My desires:
About 700 HP+ (give or take)
turning the block into a 383, so need to pick a crank.
Turbo charged

I wish to keep it fuel injected.
Need to pick the right headers as well.
It needs a new intake.
Uncertain if I should go automatic or manual? [the project car is an auto as is but ...]
700r4 ? or t-56 ?

All t56s Ive seen are about $2500 plus on a used tranny.

Not sure where to begin at with the build.
I don't wish to just carbon copy someone else's LSX build.

the engine will go into a 3rd gen nova.

first build ever, the goals are high but I love a challenge and none shall sway my determination.


I could get a:

5 speed Borg/Warner - $600

tranny, bell housing, fly wheel, clutch, and slave cyl out of a 95 camaro
65000 miles

??

The majority of borg warner or tremec trannys I find locally are from mustangs.

Hmmm, where to start. If i personally was shooting for 700 rwhp, I'd start off with getting the bottom end fully forged and rebuilt, thats alot of power. Maybe start here http://www.texas-speed.com/shop/item...d=884&catid=88 I'd go with the callies compstar crank over the eagle, not a big fan of eagle.

Pick up an LS6 intake, fast 90/90 if you've got that kind of cash. Since you're going turbo, it's going to depend on what kind of setup you go with. Most turbo setups use stock/modified stock manifolds, not headers. If you do it right a turbo setup can easily put down 700 rwhp with enough boost, you'll need some big injectors.

The top end if probably fine, I'd probably pull the heads off and make sure everything looks good on the valvetrain. Not sure a how that cam will work with a turbo setup though, probably want to look into a custom grind or stock cam. Not sure what exactly was done with the heads, even if their mildly ported i don't see them having a problem putting out 700 through a turbo setup if done properly.

Couldn't say what to do with the trans, i personally do not care for auto's unless its a track only car. That's your personaly preference. Also you're gonna need a beefy rear end if you're going to put down that kind of power. Make sure you have the right gear ratio for a turbo setup.

This is all my opinion, just throwin it out there.

Do you mind me asking why is that? {no it will not be a track car}

btw thank you for the ideas!
really Im doing lots of reading and listening to a lot of suggestions to come up with the best plan.

thanks!
