But believe it or not, I have seen many 300ZX's in the BPU area run door to door with BPU Supra's.

P.S: With a good driver, a stock TT will run mid to low 14's. Auto's, high 14's to low 15's.
MID to low 14s? More like low 14s to high 13s.

Correct, and yes I own one. It might be possible but the fastest I have ever seen for stock is 13.4 but only once, other than that they are from 13.7-14.1ish

I used to have a TT 300zx with intake, and full exhuast and 14psi, on 555r's i ran a 12.72 at 110 with a 2.001 60ft. And now i own a bolton ls1 on 100shot, and i must say, the camaro would eat it alive on the 100 shot, as far as bolton, theyre probably equal

Intake, intercooler upgrades, full exhaust, upped boost, and drag radials would get you there from what I've seen.

That's already more than "a few".

this car is nowhere near light. u could do it around $2500 if you get good prices on stuff and do all the work yourself
you car is 3400lbs? this car is a 3400lbs but I am not here to argue v8's are cheaper to mod to make faster

It's irrelavent how much it costs to install parts, really. My point was simply that it does in fact take quite alot to put a stock 300ZX TT into the low 12s.

It's not very comparable to the LS1 at all - In terms of mods, reliability, etc.

Its a turbo car. Turbo cars can be modded easily, end of story. Would I want to work under the hood of a 300z tt? Hell no......Seen that nightmare. I have small hands and wouldn't want any of it. I used to think fbody's were bad.

I have seen a couple with just a few mods run pretty damn quick. I also saw one go through 3 motors too for only 450rwhp. He would get the motors from japanese import place. All 3 ended up having rod bearings go. One grenaded nicely.

They are fast,moddable,good looking cars. A little overpriced but then again everything in the import market is.........

I've seen full bolt-on LS1s that still couldn't hit 12s, and I've seen one that hit 12.99 @ 110mph with just a whisper lid... there is no "formula" for what it takes to get to a certain et, because every car is different. Why do you try so hard in every post I see to discredit every car that isn't GM? I understand preferences and whatnot, but 300ZXs are still cool cars regardless of whether or not an LS1 F-body runs a couple tenths quicker

Edit: And since when is intake/exhaust/intercooler piping/boost controller not "a few bolt-ons?" Does "a few" mean 3 specifically?

eh, there are cheaper ways to do it, but who wants to cut corners. NA subframe 4:10 gear swap, throw the boost higher than 14psi on stock injectors and risk blowing the engine.

Its like anything, im sure my ls1 could run a 10 sec 1/4 if i put a 250 shot through it.

but all in all, from a person who has owned, raced, modified, both LS1 F-body and tt 300zx, the Camaro wins in every catagory except handling.

But who cares, my car is a straight line car anyway.

Injectors shouldn't be THAT bad......I bet someone could figure out how to run cheaper injectors on a piggy back engine management system like megasquirt.

I don't know a ton about 300z's but I would hate to think that expensive injectors are holding everyone back. I know I could figure out a cheaper way and have better tuning ability. Necessity is the mother of invention.

Someone wanna give me a 300z tt to figure it out?

Those friggen things still sell as much as my car 10 years older and with more miles.
