Engine swap suggestions
Okay guys I have a 1990 300zx. The stock motor isn't completely gone but I don't think I want to go through the hastle of rebuilding it. So instead i'm thinking about swapping in a v8..I know the vh45 is a pretty popular swap for these cars but I wanted to know what other options are out there? How reliable are the vh45 motors and what kind of power can they handle? I originally wanted a ls swap but they are a little bit out of budget right now..So throw out your opinions!

Welcome to ZDriver!
Endless options. It all depends on your skill level and budget.
http://en.wikipedia.org/wiki/Nissan_VH_engine
It only puts out 278hp / 292ft/lbs torque. It's built like a mother-trucker because it's for the SUV... so it COULD handle more hp (which costs $$$). But 278hp flywheel is A LOT of work, for little increase of power.
So... what is your budget?
VG30DETT
2JZ
RB26
Supercharged LS7
I could name every high-hp engine known to man... kinda hard to tell you what motor to swap into YOUR car... especially without knowing your budget or skill level.

Do you know how much hp/tq they will hold before they need to be forged? It will end up being rebuilt anyway, but just trying to plan things out!
So... what is your budget?
I have about 2k to spend on a motor but the cheaper the better. The actual swapping/fabricating will be taken care of, i just need to figure out what motor will be the best for me.

Haha i'm trying to stay away from the turbo motors but its still an option..Every turbo motor i had (redtop sr20, turbo ka24, and now this vg30) just didn't seem to want to stay running. Like i said, my first choice is an ls motor. But they are pretty expensive for a full swap..Anyways, thanks for the reply!
Dollar for dollar, there is rarely a cheaper way to make hp than by turbocharging. I suggest doing research... real research. There are plenty of websites and books / ebooks in pdf that go into great detail about making reliable power.
The ideal motor swap is the VG30DETT (actually, the "real ideal" is to just start with a Z32TT)... because it's already designed for the Z32. Stuffing in any other engine will also require modifications like steering, suspension, motor mounts, transmission mounts, a/c, wiring, etc. If you're up to that and have the time and $$$, get on it!

No clue on "how much it will hold". That's relative to "what it is holding up to".
Turbocharged motors have [require] tighter tolerances than n/a motors because they have to endure more pressure & stress. Since you are apparently going to rebuild any motor you choose, why not just start with a strong turbocharged base?
