300Zx Tt Potential

[scotty nm35]

I just finished working on a 300zx TT, full twin cooler piping and twin 3 inch exhausts. Anyone that thinks they are hard to work on has never seen under an M35 Stagea, that's for sure.

The owner is wanting 450kw with ethanol on a built engine, running twin 2860's. Going by the 350kw run in tune on 98 it will make that no problem.

Are there any GT28's that would have an epic whistle like a GT3076?

[AngryRB]

Assuming the car was a manual with basic exhaust mods, good service history etc what are the chances of me dropping in some 850cc injectors, E85pump, nistune and E85 with the stock turbo's and it making 250rwkw's?

Have a look at this thread off one of the US forums, you'll need to sign up to view it though

He's aiming for 800hp with an internally stock vg & a pair of GTX3071's, granted US power figures could be considered 'optimistic' compared to aussie ones but worth a read. & have a look through the build section on aus300zx.com, plenty of members doing builds aiming for 350kw so easy to get an idea of what's involved.

Im getting used to PITA setup's, the top feed rail on gtst is something id like to forget in future...

Just throwing idea's up at the moment, also considering a Toyota Prado 3.4L petrol for something different, looking for best bang for buck for under $10k..

best bang for buck under 10k would have to be the my00 wrx in my option

Just remember when looking at a 300zx is 90% of them have seeious electrical demons and most of the water hoses are perished and require replacing. They are also very light in the rear and have trouble with traction at standard power levels.

Also they are harder to work on then a gtst (won't say skyline cause the Gtr is a pain) and good ones may be harder to find

Did you just ignore the fact that a bunch of Z32 owners came in here prior to you posting this and tried to deter people from posting bullshit?

Everyone I've driven has had wheels spin even at standard power levels, so there is no needs to get sooky about it

because every dead shit seems to throw on crappy china tyres or even worse, bald ones. I've driven 20+ different Z32's and i can guarantee the only ones that had wheelspin issues were the ones with high hp.

Dude read my previous comment. 250rwkw is attainable on 98 on 16PSI, its been done before with a good tune. There are some in the 11's at 120+MPH on E85. Turbo wise you can turn them up to 24PSI(look at the compressor map of the turbos, also confirmed by people who have done it) but will drop back to 17PSI by redline due to the turbos choking. Highest i've heard of that has backed it up with MPH was a 450rwhp run. This car runs 11.4's at 121MPH another car has run similar on the dyno and ran 11.23 @ 124MPH.

[AngryRB]

that's massive meat under the curve, makes me wish I had a 300zx from the start, would of got a better result than my gtst..

+1 for super dragger's comments. 250rwkw is pretty easy for a Z32 TT, even on 98Octane and standard injectors (although you'd prefer the 555cc's at a minimum to have some more headroom). Standard fuel pump is good for over 450kw on 98 oct.

For 250kw you'd need

Good condition OEM fuel pump

555cc injectors for some headroom.

Larger Side mount intercoolers

Tune

Exhaust from dumps back (standard dumps are pretty good for this power level)

All your maintenance up to scratch

If you are running E85 and put some more boost into it I'd expect over 300kw. Mine is making 320kw on 20psi (98Octane) and I am going to run it on E85 soon and see what it makes.

I wouldn't really listen to the people saying they have electrical issues... I can't really think of any common electrical issues and they don't suffer from the coilpack issues that plague skylines. Probably would budget for a S2 PTU (as per s2 r33 GTS-t). I've had mine for close to 7 years and have never had an electrical fault.

How many have you driven? They don't have traction issues at standard power levels...

[JSFF35]

Got this one for sale, a really nice example, a lot of the work already done.$10,000. Owes about 40.

[r32-25t]

over 20, I use to work at a compliance workshop 10-13 years ago when imports just started to become popular and 300s were a massive market

[eightsixboy]

Don't forget though that there pretty boaty at over 1500kg compared to a r33 etc.

I have never driven one but knew someone that had one, he told me they are a great car just a bitch to work on

[Rob260]

How does a 300ZX Twin Turbo compare to a R33 GTS-T? Considering wether its worth it to buy and modify it to hit the 300kw's.. If the RB30/25 is a torque monster can the 300zx be similar with similar, what im after is a fairly cheap reliable 300kw for the street and thinking of doing Injectors,computer,Eflex and 18psi on stock turbo's to get close to 300kw if I bought one.. At this power level with the R33 it was frying second gear and a handful, could I expect the same with a 300zx??

Pound for pound the potential from the 300zx is far greater than the R33.

More displacement

Shorter stroke

Forged Crank

Forged Rods

More torque

That said there is far greater aftermarket support for the RB platform, and being a "simpler" (is that even a real word?) configuration is much easier to work on.

Dunno about traction issues -mine would spin 265 Nankang's on a stock motor, but good tyres make all the difference.

Also there's a world of difference between losing traction on a hard launch at Maccas compared to losing traction at the top of 3rd haha

Again pound for pound the Z32 with wider footprint should be more stable than the R33....

[Rob260]

ok well assuming it has good turbo's and we don't need to remove the engine, what potential does it have with ( stock turbo's apparently are garrett) to make over 250kw with E85 and say 18psi??

would it be a push in the seat experience or lacking????

Stock turbos will be very responsive and easy to make 250rwkw with E85. Stock turbos make an easy 220 with bolt ons

Dyno below is when I first bought my car, it had an HKS pod filter (which are crap), 2.5" cat back exhaust, and a GFB manual boost controller

Throw in intercoolers and you could wind the boost a little higher. Throw in more fuel and you can go a little higher again.

On E85 it'll smash 250 out of the park with an even better curve.

Consider for E85 though you'll want bigger injectors, probably Sard 800 just to be safe.

[eightsixboy]

Don't think e85 is really 'daily' material, not yet anyways.

I personally think there a great car, just to bad most if not all on the roads these days are farked, they always seemed to be owned by chromed wheel wearing, autosalon paint spec bogans, atleast in vic anyways.

[scotty nm35]

5 years I have been running mine daily on ethanol, you must be a pansy Paul.
