as with anyone who owns a Corvette.. the mod-bug has got me sick and I am in search for more power im definitely looking in to doing FI in the near future, i recently finished basically all my bolt on mods on my car.. right now my 98 coupe mn6 is pushing 396/386 with full exhaust stock Z heads/intake and a cam.
I have been thinkin a lot whether to sell the c5 and just get a newer c6, I'm still weighing out my option... although i already have my reasons why a c6 would be good, I would still like to see the possibilities on my 98 c5..

so if you guys can school me about FI and what I can do to make great gains without having to do major work., id like to reach 600 if at all possible on a ls1 ...

 

600 on an LS1 can be done with a bolt on centri kit.

 

I know i have seen many over 600 but how long does the motor/diff/tranny last? I understand bigger hp better clutch ... but just tryna see what kind of maintenance are needed and what supporting mods.

 

If you drive it nicely and dont drag race a lot it should last a good long while. Wirh that said wheel hop kills diffs and transmissions built or not.

 

Was thinking of getting head work on my current 243s before summer.. Would I benefit from this with FI? Or should it leave the 243 stock

 

With a good tune at 600rwhp a really long time. Tranny a diff durability depends on the driver and conditions. Regular oil changes. A good tune.

 

Waste of money at your level. Leave them stock.

 

That's good to know.. That's 1500 I can use toward the sc setup.. Probably a good idea to get a list of things I should and shouldn't do to the car .. But ur saying 600 is a longways for my car ?

 

Yep stoxk heads with good valve train will work fine.

 

600rwhp with a ls6 top end is a piece of cake with a centri.

 

And as for supporting mods go.. What are some of the things that will be needing change and help prolong the motor..sorry for all the questions I'm new to this whole FI

 

I am in the mid/upper 600's on my last pull. I haven't pulled the heads off my LS6 yet.

Not to say their isn't gains by doing a really nice set of heads. Look at Al's Z06. Stock bottom end and it runs low 9's.

 

get a better fuel pump comes with most base kits! run the stock clutch untill it needs a upgrade.

 

so whatever comes with the base kit plus a better fuel pump can get me there?

 

yes I would get a step up from the base blower for futer sicknees you can run a bigger pulley on it to lower the boost and a bigger blower now is only $200.-350 more

sounds so easy... why didnt i go this route sooner?

 

IMO if you're in the 600 RWHP ballpark on a stock engine, supporting mods are a waste of money for the most part.

Drop 6K on a supercharger, and you can make 550-600hp, so why spend an extra 1500 on headers to get you 40hp or whatever, when you can just make an extra pound of boost and get similar results? And do you really want 640 over 600 hp when your tires can't even hook at 600, and 640 just means your tranny is a little bit closer to biting the dust.

If you're going to start doing supporting mods, I would start with head studs and new head gaskets to help the engine handle the boost.

Also look at the DTE or ECS trans/diff brace. They're about $400, and easy to install if you're already putting in a new clutch, and will help your drivetrain survive the power better.

 

He has a 98 so he has a return setup. The pump that comes with the kit should be fine for 600rwhp. He could add a second 255 pump for cheap though if he is planning for more down the road.

 

unfortunately i was one of the guys who chose to go N/A route and hoped for 500hp . i have a full exhaust system with LGpros no cat and a cam on the car... after spending XXXX amount of dollars on parts and labor and with the gain i got (396hp/386tq) i decided to look in to FI thats why im asking all the questions... but if you guys are saying 600hp bolted on to my current set up now for 5-7k.... i say thats worth the power/dollar ratio!

 

I was told since my 98 is one of the older gen.. PCM upgrade should be done for ease of tuning?
