The car is a 2001 Transam WS6 M6.

Only mods done to it are a cat back.

At this point in my modding, it's either go with long tubes, do a head/cam package and call it good on the engine mods, or go with FI.

Which method would be best for a daily driver? I'm looking for reliability, if there are any street issues I'd like to know about them as well.

Thanks very much in advance.

FI - No question.


Of course - how deep is your wallet?

boost is addicitng so be prepared to break ****, if your not prepared to jump into a pit of never ending spending then go heads and cam, your looking at one hell of a combo to get 550rwhp out of a H/C combo,

gas mileage will be better w/ FI

I think you're going to have to get really wild to get to 500 rwhp N/A.

Why not do a normal heads/cam/headers to get you around 400 rwhp and add a 150 shot for occasional use?

'Cause you're going to need a big bucket of money and a full crate of patience to do the FI route correctly.

For streetablility then your answer is going to be FI. But like stated above you better have the funds to back it up, because it wont stop there. One you get a taste of the boost you will want more and more and then thats when you start breaking stuff.

But IMO if you want something reliable(as long as you dont go to big) and less expensive then H/C is the way to go. IMO nothing beats N/A power. Goodluck.

Go head/cam and be happy with whatever you get. FI will cost you way more than you ever budgeted. FI is stiill king though.

Email Jordan Musser, you can find him on this board. He has done some nasty solid roller ls1's that have over 500rwhp, and I dont think he spent too terribly much on them.

If you want 500 NA using a 346, you'll need the best of the best. AFR, TFS & ETP are making 470-500rwhp on a regular basis now days. Going this route will be much cheaper, much more simple, and will give you alot less headaches than FI.

Go with some trick flow heads and a ed curtis cam and call lg and find out when their pro f body long tube headers are coming out get an electic water pump and see when ETP is coming out with their new cathedral port intake and run a 90mm TB you will have over 500 rwhp and be streetable and save a ton of money over FI route and it will be more reliable. You will have a sick setup and be hella fast!! That is what I would do. Trust me I have done my homework and then some. These are all the best of the best parts.

Its gonna come down to what you want to spend or willing to spend. You can do a reliable F/I kit and get 500RWHP and salavage your DD abilities and MPG. Either way with 500RWHP or more something is gonna break if its not upgraded. Regardless if its F/I or N/A. I say find a few guys with the power you are looking for and take a ride. If you never owned anything over 400RWHP though a moderate H/C to get you about 420-450 is going to feel fast as hell over stock. Take a ride look at your check book then decide

503rwhp with decent gas milage

500rwhp N/A is not going to feel very street friendly. I have a little over 400 and it feels like I'm driving a race car. It all depends on what you can tollerate I guess. With FI you can feel stock untill you give it more gas. I went the n/a route first and now I'm adding the FI. I probly would have been better of just starting with FI in the first place. Now I get the race car feel and then the FI power on top of that, should be pretty sick but I'm sure glad it's not my DD.

500 rwhp NA on a stock cube LS1? Drivability = teh suck.

I appreciate the responses so far tremendously.

Only a few more questions then I'll have enough info to choose the path I will go.


What makes the streetability on a NA 500hp motor so much different from 500hp on boost?


Some responses say that it feels like driving a race car even with around 450hp NA, why is this?

Is it because all low end power is lost and you have to keep the revs high to have any power? I'm just a little confused about it. Wheels always breaking traction? What is it about 500hp NA vs 500hp FI?


Thanks again in advance, obviously very new to the high hp scene.

you'll need a big huge *** cam, that will take 2 min to find its idle, and it won't start making power till probably 4500 rpm and you'll have to rev it to 7,000 rpm. Thats hard on valvesprings. Youll have to run high compression too which wont be so pump gas friendly and you'll have to watch your timing when it starts getting warmer.

500 hp with FI is considered mild and conservative. The FI car will make torque at a lower rpm and make more torque than a na can dream of.

My advice is just to read read read, and use the search button. lots of questions been asked and answered.

My recommendation is not to waste your time on n/a unless you have budget issues.
