because i have done it properly with a forged motor, front mount turbo system. and a proper fuel system

needadvice

Will a new 99-02 PCM handle it all just fine? Or is an expensive aftermarket management system required?

What is the cheapest one to go with that can handle it all but is still a good system?

i see that u said u already had a 4l80e sitting in a crate is it built or just a new stock 4l80? No mention of a converter in there anywhere thats going to north of $800.Any kind of suspension mods at all? 1000rwhp is going to flex the hell out of your car.Any thought of what kind of wheels and tires u might run to have a chance at hooking that much power on the street?Gauges theres more nickel and dime stuff right there.Believe me it adds up quickly

needadvice

Its built big time. Was gonna go into a Grand National drag car. No stall yet. I think the same guy who I got the tranny from has a custom 9 inch converter for sale, but its for the drag track. I can send my PI 3200 in for a restall I guess.
I have subframe connectors, pan hard, LCA's, STB and I have a torque arm for it with a cross member bracket. My car has a 422 lsx now, ported LS6 heads and intake, 480 RWHP.
I'm having 3 inches cut off each end of my axles, hammering the wheel wells in like my friend did to his and I'll be putting 335 tires on the rears. Deep dish Bose rims, 18x12 rear, 17x9 front.

Like I said...all I need is the engine, turbo kit, fuel system and management system, etc.....
The $1,800 LSX block I can get is ready for boring, then assembly.

Your not going to save much money on a vic jr in comparison to the wilson. I usually have 1k or so in a full carbed style intake. Throttle Body, elbow, rails, Iac, ect.

A stock pcm is definitely capable of controlling fuel and timing at 1000 rwhp. However there are some features that a aftermarket computer will have that help the situation. At 1000 rwhp you also need an injector driver box for the stock computer to be able to drive a low impedance injector.

Fuel system is going to run atleast $1200.

I would definitely do a 6 bolt block/head.

You can defiantly plan and do it on a smaller budget then some mentioned here. Other people were right when they say you can also always buy cheaper then you can build. I have built a few cars that shared goals very similar to yours and they arent cheap but it can be done reliably. I made 920 rwhp on a mustang dyno in race form...with about $4500 in the complete motor intake to oil pan. Reliable.....


for a couple months, lol.

looks like i'm going about the same way as you... just iron 370 with a 88 or 91mm turbo....

What heads are you going with? At what cost totally assembled?

i already have a set of AFR's 225. i got a killer deal on them for $1200. only have 18 passes on them...NEW they are $2500+ theres alot of awesome deals out there if you want to get SOME used parts. can save you alot of money. there are a few people selling turbo kits on here for good price

Unless that PI converter is a triple disc, you're not going to be able to use it. Bob

How about using that LSX block at 4.125 bore and using a stock stroke forged LS2 crank. That would give you a very oversquare engine that would love to rev. Somewhere around 380 cubic inches if I remember right. Then put a huge single or two big twins on it and be done.

CALL JOSH AT KYTP. He will break it down for you.

I understand that, but you wouldn't need to spend that kind of cash to make such power. I did it with a cammed stock LS1 that had 60k miles, all the other parts were stock too. But I understand that 500rwhp was a starting point and you could go much further than my stock motor set up. but 500rwhp with a forged motor should never be anyone's goal IMO.

A $5k 402 will not hold 1k rwhp very long.Heads and intake are about right.Don't forget about lifters,gaskets ect.Fuel system will be $1500-$2k
Converter about $1k.

We always see posts of people that think 1k rwhp is cheap.Yes,you might be able to do a few dyno pulls at that power but hooking it on the road for long periods of time is what destroys everything.Ussually 800rwhp is a good goal for a street car.That will beat 1000cc streetbikes on the highway.

amen brotha-for a real reliable 1000hp shortblock you're looking at $6000.00 or so,also you got,cam,lifters,oil pump,timing chain,head studs,gaskets,pushrods,rockers,etc.

a RELIABLE 1000rwhp longblock is usually $12,000 or better.

you can't ust bolt parts together and expect it to last-it needs to be BUILT properly.Lot of things builders don't tell you,that the novice doesn't know.

i am sry but i do not see how it is going to hold up very long if it will keep lifting heads. and it will happen on a 4 bolt motor. unless you o ing the motor of coarse, and that is another 1000bucks

I'm really NOT typically the guy that says "go write a check" , but if your intention is to run a semi-reliable 1000rwhp street car, there are a few on this board that can "get it done":

-Nasty Nate spec'd fuel system(bet on 2k)
-Let Shawn@VA speed build you a short or longblock. He's really not blowing smoke, he can do things and HAS done things with FI LSx motors few other people in the world have.(bet on 8-12k depending on options)
-Let Josh@KYturbo build you a front mount 91mm setup. You DONT NEED that much turbo to get there, but it will give you room to grow.(bet on $5-7k depending on options)

That's not even taking into account trans or rear. But that's pretty straight-forward.

Just buy my engine and slap a turbo or supercharger on it.

needadvice

Ok, so if I send you this LSX iron block, the Wilson intake I can buy used and the brand new 4" Callies Magnum crank that I can buy from a local guy....what will it cost to complete the engine from top to bottom with a 4" bore so its a 402ci. You pick the 6-bolt heads that will work nicely (but not overkill All-Pro heads or others), cam, rods and pistons and proper compression for my goals. And of course all the little things like gaskets, bearings, studs, timing chain, etc.....

PM me with info if you like. Thanks

And again, I'm not trying to do a "cheap" build as in "cheap quality". I am trying to see how cheap I can do this entire project with parts, quality and workmanship that will suffice this type of build and hold up ok. Basically, I don't want to do anything that is a total waste of money and it be considered "overkill". Like using All-Pro heads, I already know that is totally unnecessary for this type of build. If I was rich, I'd just have a shop do a turn-key and tell them to make sure it's a $60,000 build and I bet they could have fun going nuts.

If it turns out its simply not in my budget, I will re-think it and just do something else.

From my experience, my first TT setruck manifold setup, I was driving around on a little over 900rwhp and this was with a $4500.00 6ltr. shortblock with stock crank and H-beam rod's,forged pistons. This motor would still be alive today if I had got it freshened up. Instead, the motor lasted a little over 2 year's,150dyno pull's, mostly the last 100 pull's over 1000hp. So yes it can be done.BUT I did change out head gasket's ALOT, when I was racing alot with the Auto. The 6speed wasn't nearly as hard on the head Gasket's. So with that said here is breakdown, some you can get cheaper and some a little more expensive?
Shortblock-$5000.00-includes pinned main caps
Head's- $1800-$2000.00-used AFR you can use stock rocker arms.
LS6 intake-$300.00
TB-$150.00 or so
Fuel system including rail's,injectors,fuel pumps $1500.00-2000.00
Converter-$900.00-1000.00-used
Gauges-$300.00
BS3- $2000.00-$2500.00 if you cannot tune the setup, you need to pat a tuner or have a friend that you trust tune it.
Turbo Kit-Josh is the only way to go. He can keep A/C with the truck manifold setup for you.$5-8000.00?? Not sure on his price's.
New Exhaust for turbo setup-$500.00
Roughly $22,000.00+ all the little extra stuff. So figure $23-$24,000.00 by the time you are done AND DOING THE LABOR WORK YOURSELF!!!. I am sure I may have left a few things out???
Keep in mind on the shortblock. You WILL lift the head's and push water if you do not use larger head studs and o-ring the block/heads. That cost is extra, depends on who you get to do the engine work. If you use your LSX Block you can get, then use a set of Trick Flow 6 bolt heads and you will not have that issue.
