this forum has crazy heavy traffic and it makes searching a pain. so many results, but none that answer my questions.
i want to swap an ls1 into another car and make 400whp na.
since this motor is so big i wouldnt mind moving the power curve up into a little higher rpm range and sacrifice some low end. there would still be a mountain of tourqe, right?
i want to use it in a drift car it would see high revs a ton and i would like it to rev to 7k rpm.
what parts would i need to make this happen?
brands/prices/etc any info would be appreciated.
anyone have the setup i'm after? lemme know how you did it.
thanks.

Well you don't NEED to spin it to 7000 to make that kind of HP so I'm not sure why you want to spin it that high.

But if you really want to you'll need lifters, pushrods, springs, valves, rod bolts at a minimum.

AngryRoomate

oh, i know i dont need to. i want to.
what parts to make the power though?

ls1 with all bolt ons headers exhaust intake pullies cam will put you at 400whp

I made 386rwhp with full bolt ons and MS3 cam. And thats without an LS6 intake manifold. Im sure with an LS6 manifold and ASP underdrive pulley i'll break the 400rwhp mark. And i shift at 6500rpm, if you want to spin up to 7K get the TRex from Thunder Racing.

wtf is the Trex?

WhosNXT

Trex is a cam. If you do not need to rev to 7k why do you "want to"? 400hp is easy with the ls1. You will need full bolt ons ms3-4 and a tune and you will achieve that. I would suggest full bolt ons, with a smaller cam such as a 224r or somthing simillar with a set of aftermarket heads. With this you would be well over 400 and have better drivability than with a big cam like the ms's and the t-rex. JMHO

You will need at least one internal mod for the power, and two or three to be reliable at 7000RPM.

Just a good bit of advice..... first of all there no need to spin a motor like this that high... thats just stupid.. the best way to achieve your goal while staying N/A woud be the following:

LS6 intake or FAST if you have the money

Headers and full exhaust

MTI G-1 Camshaft and springs. When you order the cam you send them your computer and the reflash it and your car will run so well you wont know what to do with yourself.

my buddies vette with these mods gave him approx. 397 at the wheels (this was on a mustang dyno by the way)

i would highly reccomend this setup. the cam has a nice lopy idle to it but one of the most streetable out there, plus it makes great power. Just my opinion....

most of a cams power will end well below 7000rpms, so why even spin it that high when you risk the motor and are not even making peak power anymore? Check the internal section for more help on what you need but if you look at most dyno graphs, you will see when the power ends and you start to risk **** breaking. 65-6800 is about the highest you will see power with most heads/cam for an LS1 unless you want to start building the bottom end up which will most definetly will have to do if you plan on sending her to 7K for any amount of time.

i take it you are putting this motor in something other than a camaro/firebird or vette since you say it will be very light and used for drifting. a agree with everyone else, 7k is alittle more than you should/would need to rev it and it would be less reliable than a 6500-6700 red line. something like suggested such as a ms3 or similar and since you'll be drifting i would rig it for a dry sump oiling system because oil starvation is an issue on something like that so i'd go ahead and spend the extra money.

yeah, agreed with slow trap, you will need a dry sump system if you plan on running circle tracks or drifting. I was reading a thread on here about a guy using an LSX drifting and how he killed his brand new motor from oil starvation. Try searching for, I dont rememeber what section it is in.

My setup sounds nice for you. Vindicator(240/244 .608/.596 113), ARP Rod Bolts, LS7 Lifters, Hardended Chrom Moly 7.4" Pushrods, Patriot Dual Gold Extreme Springs, LS2 Timing Chain, LS6 Oil Pump. 400+hp and spins to like 7400rpm.

I'm going to suggest staying away from spinning it to 7k, there is no need for it at all, and all you will be doing is putting the engine at risk to tear it up.
Kind of silly IMO.
It's not an S2k motor.....

Stock internals + 7000rpm = whole in your block

AngryRoomate

sounds good, i'll look into your stuff a little more specifically.
for years i've had a bunch of jap cars with little jap motors that rev high. i liked it, but grew tired of the shitty powerband. i know that with the powerband of an ls1 and gearing options, i dont NEED to rev that high. i want to. feel me?
the car will be an fd rx7 and i'll be doing it middle of next year. the swap has been done in that car a million times already. looking for a shell already.
dry sump, huh? this is getting pricey, haha.
cant wait to have this car on the track next year!

The stock LS2 GTO rev limiter is 6.5k and the cam I am getting has a powerband that goes to 6.5k....so how is an extra .5k RPM going to rape the engine?

Thule

i wanted to spin my motor to 7k also, and to be able to do that savely i did the following

Katech rod bolts,
Katech head studs,
high performance main bearings, cranshaft bearings and camshaft bearings,
heavy duty time gear and chain,
ported ls6 oil pump,
ls7 lifters

slow trap

iTrader: (22)

an extra 500 rpm is alot.MOST stock motors last forever not going over 6k with decent springs but when you add in the extra piston speed the rods and oiling system get stressed.if you are dead set on spinning to 7k i would put atleast better rod bolts in or better yet a set of aftermarket rods/pistons, ls2 chain or double roller, decent dual valvesprings and definitely splurge on a drysump.

Thule

slow trap your numbers are awesome,

do you see anything wrong with the list i maked? i also have the double extreme lift spings, comp cam chromoly pushrods
