What about that guy who runs 9.23 with stage 6

 

Like I said it is possible to be done, but I think you are stressing the capabilities of the cast manifolds. It is just my opinion. I also have very little knowledge of the customer that went 9.23 except that the car has a Turbo400.

 

Greg and Hal are just hard core automotive purists/perfectionists. Stop tempting us regular folk with dreams of 30+ psi.

 

It might be just me but I would always choose a tubular over cast manifold. Unfortunately, the 350z has very tight space for a tubular small turbo setup and that is why we (including myself) would have to run a cast setup over a tubular (as well as a 1/4 of the cost). Like I stated before, if you could have a fabricator make a tubular setup specifically for your intended setup, smaller tube ID, etc. I think it would outperform a cast setup. But we can't do that with the 350z as it will ultimately hang lower, slower spool, etc.

30+ PSI. Pshhh, I am shooting for 60psi and no less

 

thats just being "pussifie"d (no pun intended)... you either want it or not.. but its not some far feched idea.....

For the cost of the builds you should expect perfection and certain capabilities. You cant do it because you wont get out of the street AT(i understand th400 isnt really streatable).... others are simply scared due to a series of bad results from shops with out the experience of building high HP builds. All this arguments have been around quite a few years back in the supra world and failed....people here should listen to SP Injected and all supra shops for that matter... and stop thinking mediocre that 600 is the wholy grail fro people building their Zs.

 

I see where you're coming from dude, but I just can't see a 40psi build having the longevity that most people expect from their setups.

 

This I can agree with.......^^^^^^

If the G/Z had the room for a Tube/Turbo setup that could fit in the same place as the Cast.....which would give me better performance...then tube it is....But as others have said....going with tube for our cars ...you would be giving up alot just to get top end because of lack of space.

 

lol well 40psi...migth as well take out the wg ..that wasnt my point ....on what you said you dont drive 30 psi on the street.... you run it ~15-20psi, that wasnt the point.

 

i think what needs to made clearer here is that this is mostly a case on a production product... custom made it can be made to fit... ovbiously shotting for 1000+hp you cant just go with all off-the-shelf ... IMO

here is the one i had custom made compared to a nismo

 

check this place out.. i got my BMW mani done with these guys..

Jorge.......so you are saying that its possible to get a Tube setup to fit with the turbos in the same location as the log?? If so,,,thats something I am willing to do

 

Not sure that'd work. Jorge's setup is a big single, so it just has the crossover piper instead of a turbo. Maybe I'm wrong

 

ya but there is no reason for a VQ to have such complicated headers, and thats for a twin scroll setup (basically TT piping going to 1 turbo). the ones that SP and SFR make are simple, bc there is no reason to make them otherwise. turns are bad.

Ya the collector design could be better, but they arent making 4 banger twin scrolls manis.

 

James & rich.....

I see....

 

XKR,

have you ever plumbed a pressure sensor into your log exhaust manifold on your 800+ whp G35? I would love to know what the pressure ratio comparing ex.man pressure : in. man pressure would be on your setup! i would guess that it would be pretty high.

 

No...I am sure a sensor was not used.... But I have no doubt it's high.

 

yah, mainly...i was addressing the statement that there is no space and it cant be done...and my point is that people shouldn't just assume it cant be done, not quite feasable to do it with production kits(sure), but custom is possible...... the TT gt37r turbo Z from also uses custom headers

 

From what I was told... A custom tubes could be done... But not even the 530bb would fit in the spot where the cast setup sits....the turbos would have to be positioned the same way as the SP/SFR..... But as I have said before.... That's not the kind of performance i am looking for.... So log it had to be.

There is a guy a few houses down from me that has a TT Lambo. He has almost no lag... Or way less lag that I have with my Tube setup.... Because has TT is mounted right up on the motor where mine is out to the side. Rear motor cars have way more room to play with ... So they plan to do mine like the Lambo....I guess the same would apply to the G/Z .

 

^ So you're saying someone needs to CAST some sweet shorty tubular headers? SWEET!
