I have been soo much research to figure out the cost to build a 500 rwhp ls1. There are so many mixed results so it is hard to figure out what is possible and what is not. I have a $6,000 budget and want to know if it is possible (without nos). I was planning to over build the engine so I could add a turbo or super Charger later

Willie B.

6000 budget assuming you already have the engine, it should be doable. Even if you dont have the engine 6000 still might do it. Considering that with stock heads and a custom cam GMHPT made 527 @ 6800 rpms. That was flywheel but also no other internal engine work cam and bolt on only.

I don't have the engine but I have a guy that works at a junkyard who has a couple ls1's. I am mainly looking between 450 and 500 before turbo. But if I need a turbo to reach those numbers then I will but I would like to see if I can do it without

Willie B.

Really good flowing heads is the key, and I would say compression too but you want to add boost in the future. So great flowing heads with larger valves maybe, great cam and , maybe you reach that 500 mark or get close 475-480ish. That type of hp will be high in that rpm band though. Adding some cubes would help out (stroker kit).

iTrader: (2)

Could explain more into the striker kit? I don't fully understand that

Willie B.

Are you pushing through a auto or 6 speed. Harder to see those numbers with a auto and a 346 ls1. As I think about its going to be really hard to see those numbers if you going to build for boost. Low compression and all. But 400whp is good power for a low compression na motor, or boost she will be a beast. My car only made 272whp no boost 440 on boost 10 psi and I couldnt floor it on the streets if I wanted to keep my tires in good shape

iTrader: (2)

So what would you say is the best route then? I am rather new to this

twizle2

iTrader: (2)

Also where are you in nc? I am stationed in Jacksonville

Willie B.

A ls1 stroker kit, basically new crank,rods, and pistons. Take if from a 346 ls1 to 383 or depending of what kit you buy. But me I would just put a cam in it, maybe forged pistons and rods, and save the rest for turbo kit and tune. Stock crank good up to 600hp "supposely"

Stationed in Goldsboro, NC but I'm in the sandbox now

Wouldn't a iron 5.3 or 6.0 be cheaper and more durable than aluminum block engines in boosted applications?

camarorookie

Go to corvetteforum.com and look at the C5 and C6 forums. Guys over there running up to 1200hp and street legal.

twizle2

iTrader: (2)

I was thinking the same thing. A 6.0. But all that is usable with the 6.0 is the block I believe

dprest68

iTrader: (1)

Yeah, I was thinking the same thing.

25th327RS

iTrader: (2)

Exact reason I have a 5.7 aluminum block. The block, internals, and heads are all that is easily useable for us. I wanted a 6.0 for the torque, but was too expensive to piece a swap together with a 6.0, compared to buying a complete ls1-t56 donor car. Will change to a 6.0 when I find a good deal on one, or if the 5.7 grenades(high miles, it probably will), and I am forced to do so sooner.

Try to find a good 5.3 motor. Those things are built like champs. Seen a lot of stock bottom end 5.3 motors with turbos put out well over 500hp

twizle2

iTrader: (2)

What is the cheapest yet most durable and long lasting route? I have heard good and bad about all of these blocks but don't know enough about any of them to pick the best one. I have heard a lot of good with the 6.0 blocks but I read you can't use any of the accessories

five7kid

iTrader: (14)

Using 6.0 accessories in a 3rd gen is problematic because of the high alternator mount.

You can use f-body or y-body accessories on a 6.0 block. One bolt hole needs to be drilled and tapped on the driver side of the block, that's the only issue.

twizle2

iTrader: (2)

So let me get this straight... For a turbo or supercharger set up you want a low compression engine which in turn lowers you hp

five7kid

iTrader: (14)

You need to adjust SCR for the boost you'll be running. It's all about balancing everything together so it works and doesn't blow up or melt down - SCR, boost level, ignition timing, fuel curves, etc., etc., etc.

twizle2

iTrader: (2)

So essentially I need to get a really good tune job haha.

bungy74

on forced induction, i think the idea is to lower your compression via dished pistons or bigger combustion chambers so the turbo or supercharger has a larger volume of area to cram more air into, hence making more power.

Zach/90\irocZ

iTrader: (6)

you will most then likely need a tune if your on boost can get away with out one swapping small cam but its ideal to get a tune after completing your combo

5.3 or lQ4 6.0 for boost and call it a day 600+ rwhp
5.7 LS1 or LQ9 6.0 if you NA route 400+ rwhp depending on supporting mods

goal is reachable if you dedicated in searching

twizle2

iTrader: (2)

I have been searching all over the place looking for what I need an reading other people's threads. I just hope it stays within budget and the engine will last and hold up

twizle2

iTrader: (2)

Just curious also about nitrous. I probably won't do it but is it bad to add a nitrous setup to a forelced induction system?

Zach/90\irocZ

iTrader: (6)

depends on how much the effects are stronger with boost so small around 50 shot amounts of nitrous is a must but you better have a good tune

use meth injection

basically idea is to cool intake charge which is a good thing

just search Craigslist,LS1Tech,Ebay,Thirdgen, etc ive seen full ls1 trans combo as low as $2000 you have to be dedicated to searching

Fyi i got my Complete LS1/Rebuilt 4l60E with converter, Harness, wiring, pcm, Gas Tank, to inckude engine mounts and manifolds for around $1300

twizle2

iTrader: (2)

I have heard of meth injection but don't fully understand it. I will have to look it up. And I search the web everyday I can for Ls engines. Haha. I was trying to get a 4l90e tranny which I found a guy selling a brand new one for 1800.

No as far as adding a turbo what else comes with it? Lets say I run 12 pounds of boost. Will I have to do more stuff to make the turbo function properly?

Zach/90\irocZ

iTrader: (6)

What are you exactly trying to ask ?
just did quick search should give you a better idea on whats needed

I can do all the research in the world it won't help if I don't understand the concept behind it and what happens to the engine when you add a turbo. That is why I am asking you guys. You can explain things in better terms and easier to understand. And everyone's build is different so to understand what I need I have set a budget and seeing if is a realistic goal

Zach/90\irocZ

iTrader: (6)

Ok i Understand Completly
The Basics Broken Down

More Air +More Fuel = More Power "Hp"
Cooler Air Makes More Power - then Hotter Air !

Boost = Blow dryer = More Hot Air + Even More Fuel = Even More Power "Hp" ( use Intercooler to Cool Down The Hot Air = More Power "Hp" )
( Meth Inj is Used to Cool Down The Hot Air = More Power "Hp" )
( Nitrous Shot is Used to Cool Down The Hot Air = More Power "Hp" )

Boost is Supercharging,Blower or Turbo

Turbo use exhuast gases to Spin A Turbine To Force more air into engine = More Power

Supercharger/Blower Use a belt pulley system and its own power to Force more air in Engine = More Power

Natural Aspirated

More Cubic inches can Suck more air in Naturally in turn =More power
5.3 , 5.7 , 6.0

Bigger Cam allows Intake Valve to stay Open Longer and Open Wider
which allows More Air and Fuel to Come In = More Power

Exhuast System Headers, Catback Etc
Alows the Burnt fuel to escape more freely = More Power

Intake System, Fast, Ls6 Etc
Allows more air to come in = More Power
Yes your goals are realalistic

Heads , Porting/Polishing, 243 Heads, Aftermarket
Allows more Air and Fuel to Flow thru Combustion Chamber = More Power

What Are your Goals for your Car ?

Daily Driver or Sunday Car or Racer Car

twizle2

iTrader: (2)

My goals are for a weekend driver and enough power to race if I please. I was looking to push 425 to 450 hp before a turbo. But I don't know how much a turbo adds and I assume that depends on the turbo set up you have. Also I know for a turbo you want a low compression in your engine so I might have to sacrifice the hp before turbo to achieve a final goal of 500+

I have a $6,000 budget for just the engine

twizle2

iTrader: (2)

Btw that last post literally just explained most of my questions regarding power adders and how it works

Zach/90\irocZ

iTrader: (6)

is that flywheel or to rear wheels
and 6000 jsut for engine or 6000 for entire swap

if your dead set on going turbo then get a LQ4 Block Or 5.3 you wont be close to 400 rwhp morre like 350-300ish rwhp with LS6 Cam "still would be a fun car " 300hp is enough to get into the 12s with right suspension and tires .. then when you add a turbo you should be 500+ thats on a budget and you can use the rest $$$$ too go turbo and get parts to built your trans higher stall and rear gears and tune

while driving on budet engine

too get 400-450 hp NA you need to do alot more then just LS6 cam but it might not be idealfor your turbo setup ... you have to pick a road go NA or go Boost or you just waste money and have a mismatch combo you dont need alot off $$$ to make HP as long you have match mods and balance combo then you will have a fun ride

no worry thats pretty much the basics Barney Style

twizle2

iTrader: (2)

I'm looking for rear wheel hp. I don't want have to have a turbo but It teems like an efficient way to get hp. I want a set up that will last and break 500.

The $6,000 is for just the engine. I have another $10,000 for the rest of the swap. Looking at a 4l90e tranny and a Dana rear end. Just tryin to blue print the engine and car so when I get back from deployment I can't start it

25th327RS

iTrader: (2)

450 Rwhp isn't un-realistic at all. Like Zach is saying, you need to match parts with end result in mind. That being said, making 450rwhp on a N/A built engine, then adding a turbo will most likely become an issue. N/A engines run higher compression to maintain HP and torque, which is exactly what you don't want for forced induction.

IMHO, build the engine for your end goal. If you are sure you will go turbo, but not right away, build a low compression engine with forced internals. You most likely wot see 450 Rwhp with it, but it will be properly setup for a turbo.

If you must have 450 Rwhp N/A right away, you'll probably be at a higher comp ratio to do so, and you will be severely limited to what boost numbers you can safely run. Ask yourself, "if I can't do it all at once, can I sacrifice a little power now, for more power later?

twizle2

iTrader: (2)

I can definitely wait to put a turbo/supercharger on. So I guess that I will start with a lower hp stock and add the turbo for the hp gains later

Zach/90\irocZ

Im not good with typing and words = Bad

Im Navy FMF Corpsman

What do you do ?

twizle2

iTrader: (2)

I am a mechanic with marsoc

Ya I have been searching a ton. Still trying to figure out good combinations. Definitely want a 6.0 block though but if I can't they I will do a 5.7 however I can break 500 rwhp lol

Zach/90\irocZ

iTrader: (6)

no way thats crazy i was in Marsoc also 3 years ago 1st Msob Camp pendleton las flores area

if your going boost to get ls1 block in stock form can handle maybe 10psi max thats on on good tune
unless you get a 383 stroker ls1 then that would be intresting

stick with either 5.3 or 6.0 its easier

get a LQ4 6.0 block if you decided to not go boost get flat top pistons swap out the heads to like IIRC "ls3 heads or l92" or use stock ones they flow good and ,,get a cam,, ls6 intake,, etc to reach your goals

twizle2

iTrader: (2)

I'm with 2nd at lejeune. It's a pretty good gig I would have to say

So I know this is asking a lot but could you help come up with the parts I need to I can complete my damn build sheet? Lol

I was looking at getting a fast intake, 6.0 block, and that's what I have got figure out lol

I have most of my suspension figured out along with interior but I don't know enough about engines haha. I guess now is the time to learn right?

twizle2

iTrader: (2)

So you would prefer an ls6 intake over a fast intake?

SiCkRs

iTrader: (6)

Okay from my understanding of this post you wanna build a high hp engine stock but then want to go boosted later on. This would be a bit harder because the cam you will need for a n/a engine will be a whole different thing then you will need on boosted application. I was in the same boat as you but then decided to just stay boosted and going from there and alot cheaper to reach 600rwhp goal.

twizle2

iTrader: (2)

Yes my goal at this pout is to boost it. Break 500 or get close to 600. Either way I will boost it so I need to start from there

Also will 500 hp be "dangerous" on a t top car? Just curious

Zach/90\irocZ

iTrader: (6)

theres alot of info out there

LQ4,LS6 Cam,LS6 Intake,76mm or larger turbo depending where you want the power at and when you want full boost etc etc

dont take it the wrong way but you have to search more you not going to find some one to list you every part you need to build what you want
you mightest well pay some to do that and you probably wont have a $6000 budget due to labor costs when you have question along the way the ask
its cheaper then fast intake.. but fast flow better

ls6 intake about $300-450ish
Fast intake is $800+ new IIRC thats with out trottle body or Fuel rail

i did quick search and found couple sites that might be helpful some 5.3 turbos other are 6.0 turbo one NA Build

www.performancetrucks.net alot of turbo guys here
