To start, My name's Dylan. I drive a 2006 Nissan 350z that I've owned since I was 16. Purchased an LSX block that came along with heads. The block and heads are 0 miles never used on the road.

block # 19260089

My current go to list for what I think would be a good purchase so far:

Bore the block out to 427
Wiseco +2.5cc Dome Forged Pistons 4.125 Bore
K1 Technologies 4.125 Stroke Crankshaft
BTR Platinum .660 Dual Sping kit with Steel retainers
Compstar Connecting rods
Cometic LSX 4.125 Head gaskets

Not sure where to go for Cams or much of the smaller stuff since I'm not very familiar with the aftermarket side of LS engines. I'd like for this car to be streetable sitting around 800-900whp.

 

What power adder are you going to run?

Cause you are going to need it to achieve that power level...

 

How much space is there in that engine bay?

Like Jay mentioned, you'll want to factor in compression ratio for the turbo/blower to achieve your power goals. What is the car going to be mainly used for? What Transmission? Many many questions!

 

I was happy thinking NA, till i read .660 BTR springs
😫

What type of Evil guy is he...

 

Turbo platform car

It'll be a turbo platform car. The car is going to be street driven often, very often. Thinking T56 Trans although I do have a CD009 laying around if that's strong enough. And the 350z has two firewalls, one in the far back and one that curves around the engine, removing the secondary firewall gives access to more than enough room for anything. Even if you don't remove that firewall you have enough room, the stock VQ is bigger than the LSX itself so. Please ask all of the questions I'm trying to get as much information as possible!

Is there something wrong with those? I was suggested them. It's not going to be an NA car.

 

Nice! Should be a fun little project. Lots of fab work for a turbo setup, but you can't argue with the power. Over the counter T56's are rated to like 700hp IIRC, tough to swing huge HP through the manuals without some serious $. Check out 4L80E's if you can massage one in the 350.

 

Thanks for the information I'll probably do that! Are there any cams rated for 1000+ out there I could run? I want the car to be as reliable as possible considering it'll be driven very often.

 

Word! The right cam is like the final peice of the overall puzzle. The right turbo(s) are the absolute key to making numbers.(extremely over simplified for sure ) but check out BTR and CamMotion for their turbo cam offerings.. They’ll have cams that are focused on lower RPM street driveability power or max effort drag, or things in between if you want to think of both worlds. (Aka truck Norris)

also, highly recommend Richard Holder as your new favorite YouTube channel. what heads came with your LSX?

 

Stock heads, could go with aftermarket ones and sell the stock ones.

 

When you say "LSX" are you referring to an aftermarket "LSX" block? or just a new 5.3 or 6.0 block?

What is the casting number on the "stock heads" ?

 

Not sure what the intent of the question is, so I'll answer both versions...

1. Is there a cam that is rated to withstand 1000+ hp? The cam sees very little actual load. From that standpoint, just get a cam. The only thing that makes them stronger is larger journals / larger OD, and the LS cams are much larger than the old SBC.

2. Is there a cam that is rated to generate 1000+ hp? This will have more to do with boost levels than with the cam. What I would do is build a badass NA spec build with lower compression. Like good heads, and a good high rpm cam for the size engine, but keep compression lower, say 9.5 to 10.0, and add boost accordingly. a 454 LSX will easily make 500 HP all motor. Add 15 psi, and you're at 1000 hp.

 

I'd like to know where he thought cams have a "rating".
It all depends on the total package as Darth alluded to.
One part will never give "XX" amount of power without knowing the rest of it.

 

Yeah, I think there's some confusion going on.

Dylan, this is what people generally refer to as "LSX" blocks, LSX Engine Blocks; Chevrolet Performance.

Anything else just gets referred to as its three digit RPO code, like LM7, LS6, LQ4, etc etc.

 

For a box stock unit the T56 Magnum holds up pretty well, especially in lighter weight cars. Since he already has the CD09 I'd use that, they are pretty strong, arguably stronger than some of the T56's.

 

799 on the heads, the block I'll have to grab the number off of it's sitting in a crate covered with fogging oil right now I'll check that out this afternoon.

Okay thank you!

I guess it was just miscommunication

It's a performance block crated and shipped from GM never used I'll grab the casting # off of it and look it up this afternoon.

Probably going 4L80E just to keep it bulletproof I want to go beyond with the car to make it as reliable as possible.

 

You've answered the first question of what your power goal is?

The question that should come immediately after that is, what's your budget?

I mean like a realistic budget...

FI isn't cheap. Yeah there are some things you can go cheap on, some things your definitely shouldn't.

 

I don't have a budget, as in no amount of money is too expensive for me at this moment and I am willing to throw down whatever amount necessary.

 

I'm a big fan of making as much NA power as you can, THEN boosting it. Yeah you can get there with more boost, but more boost brings more heat, more back pressure, etc.

I think for that power level I'd do a LQ4 block, stock crank, aftermarket rods/pistons, AFR, TFS or FED heads. Pick the camshaft/intake accordingly to where you want your powerband to be at, then size the turbo(s) to your desired power level.

Oh, and over build your fuel system, especially if you are going E.

It's crazy that you can make that much power nowadays with off the shelf parts.

 

Using the block I have, will probably do what you suggested. Was probably going to throw it in the car NA and see how that goes before boosting it. My family has a variety of 1000hp+ cars I have no issues with control I've had plenty of hours behind 1400hp cars.

 

You'll need to look at dished pistons for this boosted 440 unless your plans are to go E with Meth injection or just straight M1. Could reach 800-900rwhp on 93 with a different set of pistons, especially if this is going to be streetable as you stated.
