So I'm preparing to completely rebuild (if not replace) the motor in my 99 Z28. It's not dead or seemingly even close, but while I have the money to do it I want to get it out the way but while I'm at it, I want to build it to its intended purpose. I really don't know what that is yet. I am looking for something powerful and unique. Costs arent a factor but I don't want to go insane on it either but I am more than aware F.I. isn't cheap.

I was thinking first, keep it simple, rebuild it to a forged LS1 346, or maybe stroked to a forged 372 or just dumping the LS altogether and dropping an Iron LQ4 / LQ9 in there with heads, cam and 7 PSI from a Magnacharger. The reason I chose Magnacharger is purely for asthetics. I like the way they appear nearly stock over a pro-charger but am aware pro-chargers make more power. I "could" go with a ProCharger but I think I would rather turbo.

And thats what brings me to my next theory.. I LOVE the way the APS Twin Turbo Kits look, although they no longer make them. I found some turbo headers on eBay and was wondering what if I installed the turbo's on the side of the motor under the firewall like the APS's are installed, or if that was a possibility? I would definately get a Tubular K-Member, but want to keep the A/C. If I went this route, I'm going with a LQ4.

Input?

I think you should do a crazy twin supercharger setup.

lol. Is that even possible?

I don't see why not. It's pretty stupid but it is doable for sure.

That's dual prochaegers I do believe. Or centri's which ya that's been done quite a few times. I guess we were talking about two roots blowers

Yeah there are 2 roots chargers in action. I still stand by what I said though lol. It's doable but pretty stupid. It's a completely flashy thing. You can hit 1200hp with a single blower promise you that

I think they are twin Rotex blowers actually. This was done by W2W (Kurt Urban) back in the day of my memory serves me right. Think they were a little short on blower but there are bigger ones out now.

Why would you put all that money into the motor to put a small SC on it?

Mainly for ease of installation and reliability.

I was a bit hesitant about Turbo'ing although I know it's superior in terms of power. Here's a question, do you think a stock LS1 no internals modified will be able to stand up to a Magnacharger?

Or even if it could, would it be more cost effective to just build the motor and turbo?
The Magnacharger is still pretty up there, about $7k - installed ontop of a STOCK LS1.

Twin Turbo'ing, I'd have to build the motor to handle it (easily a minimum of $5k) and then the twin turbo setup itself can range a good bit but probably wont be done for less than $7k for the actual system.

So on a STOCK LS1 the Magnacharger would be about half the price .. but on a built motor it would be about the same...

There are plenty of stock LS1's making 700hp +

The bottom end will support that much? I have heard that the weak link are the rods and from I have seen the limits on a stock LS1 was about 550 - 600ish HP before risking catastrophic failure. I don't mind spending a bit extra for peace of mind. Thats what I'm mostly concerned about.


But lets say I did just keep the motor stock (200k mile motor) and slapped a magnacharger ontop of that, should that hold up pretty well?
