I've been looking to upgrade my Z. I got a redline with a Turbonetics slapped on pushing around 360 rwhp. It's an auto so I lose a lot of horsepower for the psi I'm at.

I'm to the point where I need to either get another car. Or mod the **** out of it cause I think I've hit my top out point. I want more!!!!

I've been looking into building the block, possibly stroking it to 3.8 or above and putting on a nice TT kit, but I also have this itch to put in an LS2. I've read that I could add just a cam and be making like 400++ rwhp with that ****.

I bought a '88 302 Mustang a while back and never much got to drive it since it ended up being a piece of crap, but that feel and sound of the V8 would be crazy to see in my 350z. I'm doing lots of research on both, more so the Ls2 since I've pretty much already stepped foot in the boosted world. Let me know what you guys think about this situation. I got plenty of time to figure it out and wouldn't mind some input or suggestions.

I'm looking to either build the block and keep the Turbonetics. Build and go twins, or go with an LS2 and possibly combine that with the 60-1 Turbo I already have. I know it's ultimately what I decide, but I've been comming to this site for a few years now and love the Z world and all that it has to offer.

So, what do you think I should do? Get a LS2 or Twins or ......370? GTR? a life?

 

whatever you get hopefully a manual is in it!

 

I live the ls2 swap in the z and I've seen a guy on the net that did his fully built for about 15k. If your looking at a gtr then that's probably in your price range lol if you want alot of power you could just do a gtr with a switzer p700 or p800 package but that's a nice chunk of change. Probably around 100k. I've seen the switzer p700 package online for like 16.5k

 

LS2..

NA - then when you want more - have at it..

 

TH400. Perfect for 1/4 mile

 

LS2 in a Z is just sic! When you hear that deep growl from such a small car, there isn't any options here.. Do it!

 

If you're doing a LS swap screw the LS2... At lease get the LS3 and if your a real man (LOL) drop a LS7 is that bish!

However I was considering the same thing (LS swap for my TT-VQ) when working for EnglandGreen (Corvette performance shop) but found it cheaper just to build my block and up the boost.

 

Only problem is that I can prolly get the car swapped out with the Ls2 for as much as just the Ls7 engine alone. I can add a cam and be in the 500+bhp range for like pennies. I'm just not sure where I can find the LS2 by itself, it seems to be less expensive to buy in a combo pack with the tranny. I just dont need that tranny though.

It'll be roughly 5k for the TH400 and the LS2. And about that for a twin turbo kit and then in add rods and pistons, etc. But yeah the twin build will still be cheaper.

I guess the thought of all motor horsepower is what's got my attention for that build, but I'm still up in the air. But as soon as I get my Tax money, one of those is gonna be happening ASAP.

Too bad I'll never get any time from the drag strip out of my car now, because I think my auto clutch is f'd up somehow since the gears are sticking in 1-2-3. I'm not wasting money on that just to build right after.

 

^^^ true but ls2 build is so much more rare. Not unique but not done as much as tt. You could be super special lol plus lots more potential lol plus bad assery

 

Why not just build the motor and keep the Turbonetics kit?

 

agreed, there will always be a turbo'd z somewhere, but an ls2+ z???

 

There are more than you think. I just feel if someone os going to do the swap to invest in the LS3. I personally done a CAI, long tubes w/ cat-back and, cam job on an LS3 and seen 509whp. Not going to get near 500whp with a LS2.

 

I was thinking of putting the turbo on the LS engine, if I were to get one. Of course I'd have to get a kit fabricated for it

 

sell me the TN kit

 

I guess for the money you're gonna spend I would just build the VQ (complete longblock) and up the boost. And to be honest, it's what I am doing. No reason to do a swap, waste the money I paid for my JWT kit. Just going to do a complete longblock build, up the boost on the GT28s and call it a day.

 

lol pm'd

 

d1mon3k,

I'm just trying to figure out what your interested in ? Are you going to the Drag strip ?....or the Auto-X ?,....or Drifting ? ....my point is, what ever your trying to do needs to have a purpose. If you just want a show car then that is cool too. But it sounds like you are doing it for other reasons.
I would be asking myself what do I want to achieve with this ? Do I want a fast *** car on the track.....the Drag strip.....or just on the Dyno ?

Because I could care less what a car puts out on the Dyno unless it can back it up with some performance too ! You know what I mean ?

So after all that I say......put that LS2 in and don't stop there.....Race & max that Biotch out !

I wish I had the cash to to some major engine mods.

 

Well, it's easy to say I want to do all of that, cause who wouldn't lol. As much as I love how much horsepower, it's not the deciding factor in my decision. I dont need a dyno queen. If anything I'd wanna get the bomb *** times at a strip from a car that doesn't need 600 hp or whatever, But I drive a 350z, not a Honda. I'm in love with a pig. And I just gotta deal with the weight problem. I'm not a rice burner fan either. Maybe a daily driver or something, but I guess since they are cheaper to mod with less weight to deal with it's all good

The thought of the roaring V8 under the hood is just plain nasty. An f'n 350z with a vette engine dude. woah. I dont know 100% what's gonna happen though cause I have to discuss this more with the shop to get the plan in place. They said they're down to do it though and I have all the confidence they'll be able to knock that **** out.

 

The LS3 block is an updated version of the LS2 casting featuring a larger bore of 4.06 in (103.1 mm) creating a displacement of 6,162 cc (6.162 L; 376.0 cu in). It also features higher flowing cylinder heads sourced from the L92, a more aggressive camshaft with 0.551" lift, a 10.7:1 compression ratio, a revised valvetrain with 6 mm (0.24 in) offset intake rocker arms, a high-flow intake manifold and 47 lb/hr fuel injectors from the LS7 engine.

Isn't that possible to do with an LS2? I can get an LS2 for 4k and the LS3 costs 10k. I can get 500 rwhp out of the LS2 for much less then the 6k difference. Atleast it would seem that way. ****, there's even a junkyard in my city that has a complete LS1 engine for $650

 

An LS1 for 650 I'd do it. As far as a LS2 staying N/A; CAI, BIG cam, long tube w/o cats, exhaust & heads... I think that is around $8k-$10 installed. Not including the price of the LS2.
