How much money do you have?

 

... because this hasn't been asked thousands of times already... search. (here, TwinTurbo.net, and 300ZXClub.com)

The stock internals have been proven for over 700rwhp, so just start reading about which turbos will achieve your goal and figure out what supporting mods you need... a stage chart will help.

 

The SGP STAGE CHART should be a pretty good guide to get you there.

 

these are a few mods that im thinkin of doing as of these yr, of course im a average joe who works for a living and all. Anyways, im thinking of

Down pipes
Test pipes
Cat back
Flywheel
clutch
ECU upgrade
pop chargers
SAFC-II
boost Controller
Port and Polish Head

on these mods where would you guys say i would be with a tune and with out a tune

 

I'm not all that familiar with Z32 bolt ons but that wont be enough to push 600HP. First of all the turbo's will need to be upgraded. Second is that the stock MAS's wont read enough air to produce 600HP. And third, the stock fuel system is not up to the task of any where near 600HP. And finally, the stock intercoolers are most likely not efficient enough to tame those power levels. But with the mods you mentioned, basically your only limitations are going to be those things. Add those to your list and you've got the potential to push that much HP. But whether or not your engine is sound enough to handle it is another question

To sisqo if u have 10,250 dollars i would tell u to have z1 motor sports do it as for me i will have my 300zx 2+2 to stage 4 twin turbo some time this year as i am getting a settlement...

 

damn man thats tight that ya getting up very soon. WEll my question to the mods that i listed is where would the power ban be with those and i already have upgraded intercooler, FMIC, other stuff and ya i know wat ya sayin bout fuel and turbos, thats a must to get there i understand that i just wanted maybe a suggested route to go about it. I have a good idea just wanted to hear from you guys. Thanks and na these project is not gonna be like a couple of months its like two yrs or maybe 2.5 years thats when im tryin to get to in that time.

 

Depending on how much boost you're going to run, I would say 325 minimum to 375 maximum at the wheels. A dual-POP charger is useless at these HP levels. You only need to upgrade this when you're exceeding 400 at the wheels. If you're porting and pollishing the head, then you should look to upgrade the injectors at that time as well.

 

like do you think it will make a whole lot of difference if i dont, just cuz im gonna be getting back into the internals when i do the cams later so right now im just porting the heads just to see if it will make a whole lot of difference, becuase my brother got it done and it pulls on his Celica GT-S,

 

There is very little room for improvement with the stock TT heads... not many people bother with doing it. I'm not saying there won't be gains (with increased airflow, there are always gains), I'm just saying that the gains are minimal and won't be very noticable. So don't be surprised when you do it and don't notice a difference.

 

oo ight then, i feel ya on that. Well say when i get a tune done after i get enough parts where a tune is needed do you think it will show then

 

Not unless you have some kind of benchmark to compare it to.

Seriously though....if you get up to 600whp, then I've heard that porting the heads may give you up to 20HP, and I think that's a stretch. Not much bang for your buck.
