Best setup to get 800hp out of a 300ZX

[TTkickedin]

if you're asking to use 89-octane, you're not even ready for 500hp, anything less than 91-octane and you're asking for the engine to knock.

True.


However, 89 Octane gasoline + 100% Methanol liquid injection would actually work, DvlDoc from DevilsOwn seems to think so.

i can run 93-octane (or 91-octane if you're in california, etc.) and methanol liquid injection instead, there's no point in running 89-octane. no one should run 89-octane in a boosted car.




fyi, op, on a vg, 800hp usually requires racing fuel (or e85). and for that kind of power, a good budget is around 25,000 dollars+.

built engine, and i don't think the usual eagle or scat rods would cut it (those rods have been known to stretch around 600rwhp+), you would probably have to step up to pauters, carrillos, or crower rods. cams, forged pistons, 2.5'' intercoolers and intercooler pipings, msp manifolds, 3'' exhausts, at least 850cc fuel injectors, a good ebc, ati damper crank pulley (forget the UR stuff at these power levels, you will need dampening of the crank), and you're looking at possibly 18,000 already.

we haven't talked about strengthening the transmission and driveline, and suspension upgrades yet either. and this is assuming you do all the work.

feasibly, i would start with something more manageable, such as 450-to-500rwhp and go from there+.

LOL @ using 89 octane

[mrmoose]

Gt30r's huge injectors, bigger fuel pump, bigger fuel line, bigger piping... Eveything has to be a lot bigger! Then a good dyno tune. All which has been said before.

OR

2jz swap ha ha ha

the oem fuel pump is pretty strong, actually, you can run a dual-oem fp setup or a bosch or aeromotive as your secondary pump.

Yeah stocker is good to mid 500s. The Bosch 044 is good to. Anyways for 800 fuel delivery will need attention. I would also consider wider tires, bigger brakes etc

89 octane seriously???!??! 93 if you have it in your area if not then 91 and don't ever put anything else in there unless its higher!

And where would you get 100% methanol? Boost Juice is only 49% methanol, anything higher and you need a hazardous chemical license to transport it.

Stock pump can handle 700RWHP on the high end. Been done before, by a couple of people.

If you want to tune for 89 octane, just tune for 87 and get a Civic. There is no point in running mid grade gas in a performance car.

^ Not once was it mentioned that this is a good idea, OP, use your judgement. 89 is piss water. 93 is barely gasoline.

that seems like a recommendation to me,

all kidding aside, if 93-octane is barely gasoline, what would you consider real gasoline?
93-octane is the best that we can get here in new jersey.....racing fuel is 10 dollars per gallon+.

[TTkickedin]

would actually work, is not a recommendation. You can steal, but it's not recommended. you can shoot somebody, not recommended. You can do things, but they're not recommended. I hope we're not going to start bickering about what's a recommendation or not.

93 IS barely gasoline. It's one the best we can use here legally in the states, but in other parts of the world 97 is sometimes the lowest.. i'd consider that borderline real gas. Race gas is real gasoline, it's what makes an engine run best.

I'd really not like to continue talking about gas. I've got a nap to take.

i don't think it's a feasible solution, if you want to go to the dragstrip, sure.

you're arguing semantics ---- let me be clear ---- no, 89-octane WOULD NOT WORK, recommendation or not.

stealing and killing are illegal, NO ONE WOULD SAY "WOULD ACTUALLY WORK" for those activities.

when you say "would actually work", that equates to a recommendation. for example, 18-psi would actually work on 93-octane, that's a recommendation. you're backtracking because you got called out on it.

just admit you don't know what you're talking about.

you say 93-octane is one of the best that we can get in the USA, what country do you live in? WHY EVEN BRING UP WHAT GAS IS AVAILABLE IN OTHER COUNTRIES?

if you live in the USA, 93-octane isn't "barely" gasoline, it's also the best gasoline that we can get. let me know when you daily-drive on race fuel.

anyone can see that you don't know what you're talking about.

too many people giving advice when they shouldn't be, Tony.

Race gas is real gasoline, it's what makes an engine run best.

incorrect. race gas doesn't let an an engine run its best.
race gas is leaded, and if anything, introduces more wear and tear to an engine.

race gas lets you run more boost, that's it, it doesn't let an engine run its best.

"The report read 'Wear was well above average in the first sample from this unit. We're assuming that this is a race car, as we found quite a bit of lead (leaded fuel?) in the sample.'..."

Lead is an anti-knock additive. I would think that the reason for the higher wear was due to the gasoline getting into the fuel, leaded or not. Running race gas in an engine not tuned for race fuel is 100% pointless, as it will not run any better, but your car may be faster because your wallet will be lighter Also, FWIW, there is 100 octane AKI fuel available in unleaded by Sunoco and other manufacturers, such as VP fuels.

93 IS barely gasoline. It's one the best we can use here legally in the states, but in other parts of the world 97 is sometimes the lowest.. i'd consider that borderline real gas. Race gas is real gasoline, it's what makes an engine run best.

The 97 you reference in other parts of the world is 97 RON, which is really equal to 93 AKI (RON+MON/2) which we have in The States.

Bottom line, if you're not running, don't plan on running, or can't afford to run 91 octane or better, you shouldn't be driving a Z32, NA or TT.
