a few questions. im thinking of going from a blown 355 sbc to a ls1 single turbo.

what can stock 6.0l motor make in stock form?

i would like to go with a smaller turbo for better street ability. tell me if i am off my rocker or this kinda thing is possible?


thanks

i guess i should elaborate a little more.... i am trying to figure out what motor to look for a lq4 motor i would think from what i read looks to be what i want but i have herd there is a few different compression motors obviously i am looking for the lowest compression. um the computer stuff i will figure out later after headers and the motor is mocked in the car.

get the Lq4 those come with about 9:1CR i think. or even so get a 5.3. those are good with turbo set ups...

I picked up a 04 lq4 6.0 trying to the same with a single turbo in a 68 chevelle

There is an LQ4 and LQ9 6.0L truck motor. If your looking for low compression look for the much more popular, easier to find, cheaper LQ4 motor that was used in most trucks. The LQ9 was the high perf version used in caddy escalades, silverado SS AWD`s, etc.

You can also do a 5.3L though, Parish8 ran one of those in his fairmont with a Z06 cam and single turbo, IIRC he was making around 650 RWHP

And you can do this on stock internalls?

There is a GTO w/ a bone stock LQ9 that put down high 800's on pump and a lil meth injection, TO THE WHEEL. Are you looking for 650 at the motor or at the wheel? Only reason I ask is because 650fwhp is deff. doable and sustainable, but i wouldn't push the stock pistons/rods past 600rwhp and expect 100% reliability. Although the stock crank and block are good to 1000+whp levels.
If you are able to fit it into ur budget a decent set of Mahle pistons and Scat rods on the stock crank w/ a 4.03 bore will be a stout 370 combo at those power levels. It is also well known that the stock Z06 cam makes a great FI cam.

Oh yeah and FWIW the lq4 has a 9.4 cr and the lq9 has a 10 cr w/ coated piston skirts and slightly strongers rods. Also the 2000+ motors have upgraded rod bolts that make for a more reliable stock bottomend.

i new at this these abbreviation's whats a FI cam

and whats FWIW? lol i am sorry but ya lost me.

learningthehardway

FI=forced induction
FWIW=for whatever its worth

FI cam= forced inductions cam, or a cam well suited for turbo/supercharger.
The LS6 is a cheap turbo friendly cam.

FWIW is for what is worth.

Im building a 6.0 with a Master Power GT45. Its only a 69mm turbo with a bigger exhaust side. I bought it before too much research on here. Ideally a 76mm is about right for a 6.0 to make 650 rear wheel hp. It would allow for lower backpressure over using a 70mm. A 70 will probably get you there but will need probably need methanol injection and wont take you much farther.

My plan is to use the Master Power to start, using a air to air intercooler, and E85 fuel to lower intake temps. Im hoping for around 600rwhp.

There are also some affordable Borg Warner units that people are successfully using to make big power on the cheap.

For the 6.0, you could do it on stock internals but will have to watch the tune up very closely or you will take out the stock pistons. I would upgrade the pistons and rods to forged. Again research on here.

Heres the combo I would recommend.
junkyard 6.0 LQ4
Diamond pistons with appropriate dish for 8.5-9 to 1 compression
Eagle rods
arp head studs
gm multi layer steel head gaskets(called MLS)
02 LS6 cam
stock heads, decked just enough to straighten them
Patriot Gold dual springs
Comp pushrods
60 lbs Mototron injectors
76mm turbo of choice
Turbosmart pro48 wastegate
Tial 50 blowoff valve
Ebay intercooler
stall converter with good efficiency with around 3400 stall. (yank, precision industries, circle d)
rear gear ratio of 3.00 to 3.50

That should get you 650rwhp reliably with room for growth.

I am looking to build a nice street setup. The 650hp would be crank hp but I'll take 600 rwhp! I would like to use a stock short block ie stock heads and stock rotating a cam I would def do. I was thinking of using the edelbrock intake with one of there elbows. I'm a little unsure on the wiring and computer but it looks like this is the place to figure that out! I think I'll just start with getting a motor in the car and get some stuff to make some stainless headers. Put some miles on this tig I got here.

Thank y'all for all the info so far!

The eldelbrock single plane and rails are nice. Check out intakeelbows for the elbow.
Also check out Parish's nova thread for using Weld Els(sp) for the headers

last stock 6.0 i built a turbo for made 608rwhp with pump gas and meth.
just upgraded patriot springs, ls6 cam, pr's, and arp rod bolts.
heads did not come off. this was with turbonetics t76 turbo and 3' dp
in a m6 c5
also lq4 is 9.4:1
lq9 is 10:1 scr

LQ4 with a 76mm s400 will get what you want and more.

Well I think I may start with a holset turbo from a 5.9 cummins. Just for building and to get the car running and driving. I was reading up last night on some computer stuff I would like to do a laptop tunned setup with a wide band of course. The trans will be a built th350 to start but I'm sure that will puke. This is budget build of course I would like to just get the car going the tune and upgrade parts.

I'd use a t70.

You can use the LQ4 or LQ9. LQ4 preferrably because of the lower compression. Note:the LQ9's have better rod bolts. 2005-up LQ4's have the better rod bolts also. The stock heads and internals will get you 800 plus hp on race gas. If your gonna run pump gas try and stay around 550 hp. These hp levels are at the tires. I'm doing a similar build.

02 LQ4 w/ 05 LQ4 pistons & rods
stock heads w/ 5 angle valve job
custom ground cam
Precision T76 turbo

I'm hoing to make 800 plus at the tires on race gas w/ meth injection. There is a guy on here that can give you some great info on doing this. His screen name is hellbents10.
Good luck with your build.

I am curious how yours is going to do. I am currently working on a lq4 swap into my 85 t-type. I have a hx35 I am going to use also,(budget build, lol) with a p&p 19cm housing off a 1st dodge. Looking for some arp rod bolts from a few local guys. heads are getting ported and ls6 intake. I wish I had enough money to do a Z06 cam, lol. Anyways keep me posted and I will do the same.

i haven't started the swap yet lol.. a little delay on a new garage. i decided to go with what everyone else is running a t76

TurboBandit

how many pounds of boost are you all running these on?

I'm using a t70 turbo on my LS1.

ARP rod bolts, MLS gm gaskets, ARP head bolts, GM hotcam, comp cam push rods / valve springs /retainers, BRIB underdrive pulley, Fidanza 4.3 clutch

Stock internals, rotating assembly.

I'd like to get just over 600rwhp
8lbs do this? or will i need 10+?

How conservative are you running your timing?
