What kind of mods will it take to get 400 rwhp out of a 98 mn6?

G5X3 cam, Pulley, Callaway Honker CAI, Longtubes (catless x-pipe), Corsa Indy exhaust, and a tune. You should have no problem with an mn6. Probably over 400rwhp.

ls6 intake, heads, cam, headers will get you there. you can always go FI too.

MS3 $400 LS6 heads $900, hooker headers $600 Prices are generous..... but you'll get there for under 2 grand, not including the clutch you'll burn $1200, rear end you'll break $2400 and hours spent on the install.

So far I've got tpis longtubes, Vararam ram-air, b&b exhaust, and off road x-pipe. What should I do next? Not really looking to do a cam quite yet. What would you guys reccomend? By the way this would need to be a daily driven setup. Can this # be achieved with stock heads?

yea it can be achieved with stock heads, and an ms4 cam along with g5x3 came would prolly both get you over 400whp on stock heads

Add ported ls6's, a nice cam like a g5x2 and ls6 intake. Basically what you have and what i listed is what got me the numbers in sig.

Would it be worth the time, money, and effort to upgrade to a LS6 intake or should I save for the fast LSx intake?

My sig minus the ported 90 fast and tb, and no afr 205's or ewp (meziere) or asp ud pully.

LG pro longtubes, g5x3 cam, vararam, billy boat bullet system and a tune. 403 rwhp 385 rwtq. Sorry no graph to go with it.

LS6 intake would do if all you want is 400 at the rear. You can get with stock heads. But you do need a cam. Your choice how big and a good tune. Good luck and have fun.

You can get there with headers, exhaust system, Z06 intake if your car is 2000 or older and a cam with 230 duration and .595 lift..and a set of good heads and you will be in the 440-450 range

I made 399rwhp in my old FRC, it was a vararam, LG motorsports pro long tube(prototypes with V band flanges) headers, modified STOCK H pipe, LS6 intake, MSd wires, and a mild cam with dual valve springs. 588 lift. And tuned by diablosport.

No other mods. Car had 100+ thousand miles. Stock mufflers.

Also, we made 398rwhp on an 02 Z06, I put on a fast intake(90), lg pro long tubes, cats, and b&B bullets. and a diablo tune.

Will stock springs work with the G5X3 cam on LS6 heads? Stock pushrods okay too?
I would like to hit 400 RWHP with my conversion. If this cam will do it with what I have listed I should be looking hard at this cam.

Your gonna need DUAL valve springs,...and NEW pushrods. "KITS" should be available for decent prices. I had everything for sale, for cheap, brand new but, just sold it to pastvertical last week.

pushrods
retainers
locks/keepers(or you could use stock ones)
DUAL valve springs
camshaft
..your choice on replaceing the CHAIN. I would.

Do all those things man...you'll probably make 410++ easily to the wheels.

Don't forget about the tune. Strongly recommend long tubes and a vararam with the camshaft.

Your car will be SICK,..and it'll RIP. Not the fastest car in the world but,..very friggin fast next to alot of car.

I raced, and WHIPPED *** on a DIABLO from a 25mph roll starting behind him, and passing him at 170mph with a 220lb passenger with that 400rwhp combo.

A very cheap, sleek, supercar crusher.

Never seen the diablo again after that.
