I don't have nitrous. I said ditch the nitrous with boost idea because you're putting all kinds of strain on the engine already with boost. Nitrous hits so much harder and more violently than boost that you really increase risk of blowing something up unless it's absolutely, 100% perfectly tuned. It's doable, but the tuning is very, very critical, I'm talking hours upon hours on a dyno to get everything perfectly dialed in. I personally would never use nitrous on a turbo engine, but that's just me.

exactly thats why im going to hold off on nitrous for right now. I first want to get a feel of the boost and learn how to lay down a good tune. Then when I get another vehicle i can spend time on the dyno as much as i need. Hey spliner does your intake pipe connect to the other inlet of the intercooler or where does that inlet on the drive side of the intercooler go? thankz

I have the hot side pipe running from the turbo, to the passenger side, down into the fender area, and connected to the intercooler. I have the cold side pipe running from the intercooler into the driver side fender area and up through the whole where the stock intake tube used to be, up and around the battery and over to the throttle body.

Then what is the block with 4 hard lines comming off it to the intake manifold for?

those are his extra injectors shooting right through the ports of the runners of the intake to the ports of the head. He tuned it by ear and a knob and a great job too

I tuned it by ear? Last time I checked I couldn't see my AEM Wideband A/F gauge through my ear...

But yes, those are fuel lines for the extra injectors. My new setup will have a rail for the extra injectors instead of individual lines.

im just curiouse as to why you used extra injectors? I mean was it because you kept the stock ones in and are running more for the extra fuel shots... or did you upgrade and have the extra for a diff. purpose. Im running the 750cc fuel inj. with a 250 liter per hour fuel pump..... im just curiouse with that as to why you need the extra shots of fuel in the intake before it even hits the port of the head with the other injectors.

[spyhunter]

for extre fuel perhaps? since that was his way for solving adding additional fuel?

okay i was going to start another thread for part 2 of the rebuild LD9 and title it parts for the rebuild. But since this thread is still receiving posts well here it is. I currently am in the process of buying everything that i need for the project. I already sent the block to the shop so now waithing on them. It took me 3 hours to tear the engine down to the block. I just got my t3/t4 turbo in the mail today(looks funkn beatiful!)will the turbo manifold for a Z24 work on the Alero?( pic down below) I am new to turbo to please help anyone, thankz
and heres some pics also of the High Output Intake Manifold with the tabs grinded off with an angle grinder, real easy to do

[spyhunter]

ahh that's a top mount turbo manifold... It should clear the hood no problem, and from the looks of it, I believe it shouldn't make the turbo hit the firewall at all. Only you test fitting it will tell. Nobody I have seen is running that manifold yet except maybe one or two jbody guys.

That's a reallly new manifold to come to market.

[DOHC_tuner]

yeah I dont believe I'll will have an issue with it hitting the hood, but maybe with the firewall. So should I buy it and just try and see or does anyone else know? Considering spy doesnt know probably no one else knows help

[alerojack]

thats a nice looking turbo manifold, where did you buy that from? i also have the log style but is not as nice looking as that one and the turbo also mounts on the back side of the manifold.

[DOHC_tuner]

I havent bought it yet, I typed in Z24 turbo manifold on ebay and thats what came up.
