You think so. I know I'll get some good money for the heads and cam; probably do a package deal for around $1,900. I'll be able to sell the headers (Stainless Works stainless steel) and my 44lb/hr Accel injectors (I'll need much bigger ones), plus my TSP True Duals. All in all, what do you think the total cost in parts will be for everything I'll need for the turbo build; ballpark figure?

Would a BWS480 turbo be too big for a 5.3 application? I've seen really good things out of the BW turbos, so if the S480 isn't an option, what other BW turbo would be?

BW turbos are physically huge. Most cannot fit them due to space constraints. They are pretty cheap though. Are you fabbing a kit or buying a premade kit? I don't know of a premade kit that will fit a Borg unit. Comp Turbo has 79mm turbine wheel option you could check out.

You could probably get a 05+ 5.3 for 500-1000 depending on miles. Swapping in your LS6 intake is free and an 02+ LS6 cam is cheap too. Figure in head studs, LS9 gaskets, valve springs like PAC 1218, pushrods.

Given this will be my first build, I'll likely get a pre-fabed hot/cold side kit from Huron Speed. I will be able to reuse my head studs (ARP) if I stick with using my LS1 block. Still not sure about that though. I can also reuse my valve spring too; they have less than 2,000 miles on them.

Bump this up. With a Huron Speed hot/cold side pipe kit, what turbo can get me to my goals?

You dont need an s480 to make 800rwhp, im pretty sure a standard s475 with 83mm turbine on a t.3 will get you there... a 96mm turbine if using a 6.0

I got hurons t6 hotside kit and making my own cold side with just pre bent pipes.

16 psi on my s475/1.32ar/96mm turbine to my stock long block cam only ls1. I don't have rod bolts or head studs or any special anything. I'm pushing my luck I know. Engine has 130,000 miles on it. Still going strong over a 1000 miles so far at that level. Boost it up several times every time its out.

What HP/TQ numbers or ET times are you putting down? Your build intrigues me because you're doing this on a stock LS1.

I went 6.47@113 with a stock bottom end LS1. No rod bolts, no head studs, stock 241's, 227/224 114lsa cam and a PT7675@16psi.

Car weighed 3800lbs. with a 4l80e and A/C.

mrstepheneades

No numbers yet. 18 psi today on a pull on the highway lol. I'll leave it at that setting for the Dyno next weekend at Tick. Then we'll see what's going on. But trap 103 on 12psi and street tires leaving from right above idle. 1/8 mile.

Someone needs to pure alcohol an ls1 to really test the internals strength. Or run some 118 or something. Still think bent rods and spun bearings could be helped a lot of the time if there were absolutely no detonation.

this^^ I found a local guy who blew his motor, traded my 65k mile ls1 (lots of spray on it) for a 12 bolt. then bought a 6.0 short block for 250 from the same guy.. lol

arp'ed the motor, slapped it in and its running great.

I wish I could find a 5.3 or 6.0 short block for $250.00.

Back from the DEAD. I cant believe this thread made it to 18+ pages! WOW. I also cant believe I'm back here in a different car, but in the 8s with a SBE and T56. 8.8@163.

It looks like that may be the fastest SBE+T56 combo. Maybe 1 or 2 other Zr1 deals just slightly faster than that SBE LS9 (cheaters! LOL) + TR6060.

I'll take it.

Any others in the 8s SBE+T56 or TR6060?

It's an old thread, but I figure I'm going to kick a rod out the block or crack a cylinder liner on my boosted LS1.

You might be surprised, there's a cat I know in Texas with a TT C5 all forged LS1 making around 1,300whp with the factory block.
I made 700whp with an SBE LS1 for several years and my current car has a rod /piston LS1 and is probably around 900hp and seems to be doing fine.
LS1 blocks don't get enough love lol.

LilJayV10

It's stock rod/piston. It's on E85 and I'm pretty conservative on the tune up even at 14lbs.

it made 430rwhp with TEA ported 5.3 heads and LS6 intake.

It has TFS220 and a FAST102 now, same cam.

At 14lbs I'm guessing its 700+rwhp. Hopefully I will get it on the dyno this year.

Many years ago Matt Harland had a 5.7 twin setup and I think he ran about a 8.6 anyone remember?

I ran my last SBE LS1 car at 14lbs. on pump gas rams **** only and it was probably at or just over 700whp for four years until the new owner crashed it.
Everyone says 700whp on an SBE LS1 is like running around with a grenade with the pin half pulled lol.
My current car has a T6 turbo kit that came off an SBE LS1 car that made almost 1,000whp once and scattered the engine doing it lol.

Agreed. I think sometimes folks believe something and just keep repeating it years later.

Us having been around the last 26 years in the LS scene know that tuning and boost combos have improved about a million percent.

If I went back in time and told 2003 me I'd be hitting 20-22 psi in an SBE with pump E85 in 2024, I would not believe it. I think the early days of LS + boost was pretty bad actually but by around 2003-2005 people were figuring things out.

For sure, I remember reading about Kurt Urban pushing the 4-bolt LS engines so hard that the head gaskets would be leaking by the end of a pass and then seal back up on the way back to the pits lol.
Having grown up around old school SBC/BBC stuff, what we now do with LS engines is still incredible to me.
