I recently purchased a 2001 LS1 22K miles. What would you recommend I do to bring the HP up to match the 405 HP Z06? Will the LS6 intake and new aftermarket cam bring me to those numbers. I will be running the engine in a GTM with high flow cats. Any suggestions would be great.

heads will make the biggest difference
dont qoute me but 243s(might as well have them milled and a mild port job)
a 02+ zo6 cam
yellow springs
ls6 intake
a good tune
thats all that makes a zo6 different if im thinkin right
that should put u where u wanna be

I made 340 rwhp with only a slp lid, smooth bellow, ported TB, Descreened MAF and hooker catback. My friends 2003 Z06 made 342 on the same dyno.

Your building a GTM? We are building one of those at the company i work for, corvette recycling.

must also remember that a z06 also weighs a few hundred less pounds my z made 350 and 370ft stock

The Z06 also uses the MN12 6 speed right. Doesnt that make a big differance also?

Why Limit Yourself To A 405 Flywheel Hp Rating???

2001 LS1s already have the LS6 intake. An aftermarket cam could put you well above LS6 performance.

you can do a nice cam and a nice set of heads and make over 500 at the crank.

Yes I am building a GTM or Better yet Midwest classics is building it for me. I want to limit the TQ output, if I could get large HP without the large TQ. that would be ideal. The car weights 2250Lbs so 405HP will be a 5.56 power to weight ratio. Extra power is always good, but the LS is bolted to a Porshe G20 transaxle. They say the tranny will hold up to 500 Ft Lbs but better safe than sorry. What mods would you recomend? Does anyone have a recommeded cam grind for high HP/low TQ. Ideal I would like 400-450HP at the flywheel and no more than 450 TQ.

The engine it is out of a 2001 Convertible Vette if that makes any difference.

Hearing someone say they want less torque..... it simply scares me.

he just wants to be safe!! but when u do start adding all the good stuff to the motor these engines tend to get more HP then torque sometimes! but u can go with a cam only motor pushing above 400WHP, im sure that will be plenty for u!! if those mak our cars fast i can only imagine with a 2250lbs car!

Ask around - Patrick G may be able to custom-taylor a cam for you that'll up the horsepower while producing very little extra torque. A set of high velocity heads sound like something you'll want to stay away from, since those are where you'll pick up some nice torque gains.

wtf? you dont want torque?? Umm do you not want to get up and go fast or what??

His car is 2250lbs, it would just tear up tires. I'm looking at getting less torque in my M3 when it's running. It will be around 2500lbs.

Don't get me wrong my current car has 588Hp and 617TQ. Lots of down low. I want something that is a high rev, with the power band past 2500 rpm. Many European cars Ferrari, Maserati, Lotus have low TQ but still gets great 0-100 times do to the high rev. The GTM is an American supercar with sub 3 second 0-60 and sub 6 second 0-100 using a stock LS7. It has the exotic looks with the American mucsle. I have a Buell (motorcycle) Crotch rocket looks with HD American motor. I figure a 450Hp LS1 should bring me at or just above the 3 second 0-60, 1/4 mile in the 10's. Maybe some funny gas at some point.

The car is mid-engine so the weight sits on the drive wheels. Fom what I understand it is very hard to spin the wheels. That being said a new transaxcle is upward of 18K. I don't want to replace it because I plan to drive the car to it's limits.

You Dyno seems way high you are usually in the range of cars with LT's and a tune, and your friends Dyno is the lowest I have even seen a Z06 dyno, I have seen a few 01's in the 340's but all of the 02-04's I have seen are 355-365 range.

What is the cost to do a cam swap with Springs and rods?
