i know there arent that many options for boosted maxes but if there were, what would be a better choice? turbo or sc? since the sc probly has more low end power(since turbo needs time to spool) is it right to assume that a sc car sprints faster 0-60 and/or quarter mile than a turbo max? this is a topic i really want to find out about so any info will be appreciated.

 

no

 

u can get full boost on a turbo max at 3k rpm, on a s/c max you can get full boost at redline

 

I think someone asked this question in the SC/TC forum.

currently, turbo kits are developed for 4th gens and I know few individual who installed it onto their 5th gens (2k,2k1) and they did a lot of work to customize it for better fit.

on the other hand, SC kit by stillen is easier to install, but it does come with few problems like belt alignment. I would prefer an SC kit because it is easier to install. But for getting more boost out of the SC, you will need to swap the pulley and it is really a pain in the butt to do. oh~ another good thing about SC is that you will never overboost.

acceleration-wise. SC does have a better response at low end. However, it has a linear boost. So the faster the crank spins, the higher boost you will get. This means that you peak boost will be at 6400 rpm for a very short amount of time. TC cars get their boost at a much lower rpm, they will get their peak boost once they hit 3000rpm.


the seller of the SC kit has a turbo max now. He gave me rides on his previously SC'ed max and currently TC'ed max. I felt TC max is pulling harder @ 6psi than SC'ed max @ 13psi peak boost.

 

Not to mention the S/C is parasitic in other words it take power to make power. The TC is running off exhaust so its basically more efficeint.

 

I guess they all kinda balance out, Turbo makes more HP = More $$$, Supercharger Makes a tad bit less HP = $$$.

Its all personal preferrence. If I have the money I would go Turbo in a sec. If I don't have that much money, I'll probably just get a Supercharger w/ Nos or something.

 

But there isn't a real turbo kit for the 5th gens, there's a reason makers offer "free" install, it's because their parts aren't good enough to be sold as a kit and it takes an installer to fudge it around to make it work

 

im guessing that its better then to wait for a mass produced kit instead of putting together my own kit from parts? especially if i have limited mechanical know-how

 

Mass produced? There are 3 turbo 5th gens that I can recall, thats all. Maybe 5 at the most considering we dont know the other two. They are all custom installs and each diff from one another. You basically need to have it cutsomized to fit your car since there is not much aftermarket support for out cars.

 

Certain types of super chargers work differently. I know of the roots-type blower, and the centrifugal type blower. Someone on here may have to outline the differences, as far as I know the centrigual type does not see consistant power at all bands, whereas the roots type is more consistant? (assumption, someone clarify that). I will say this, the turbo works off exhaust, and not a pully, also the problem with spooling is why they make sequential turbos, and people use stuff like BOV, and modified wastegates to deal with lag issues. Some cars have very little turbo lag, I think most supercharged maximas are the voretch, which are centrifugal, and all turbo setups are completly custom, so are variable. I think the turbo setup would cost way too much, and the supercharger is a kit, so it's far more practical.

 

Sorry if this has already been asked, but...
Is it possible to have both an SC and TC at the same time?
Wouldn't that be nice!

 

if you really want the turbo. go to turbomaxima.com or turbokits.com they both have a kit for the 2k 2k1 maxima.

 

There seems to be alot of mis-information in this thread.... I hope I can clear it up a little bit. As a 2k1 owner, a former owner of the Stillen SC kit and current owner of the PFI turbo kit, I have experienced both worlds.
First the whole issue with boost...which gives boost faster; the SC or the TC...In my experience, the SC starts to boost at very low RPM and as soon as you put your foot on the gas! Where the TC depending what size TC you have, can take up to as much as 4k to START to boost. I think since my turbo is a bit bigger I boost at around 3500k
Hitman got it right:
"HitManSE Not to mention the S/C is parasitic in other words it take power to make power. The TC is running off exhaust so its basically more efficeint."
But I can tell you this... I was running 11psi on my SC and I'm currently running 5psi on a t4/60-1 turbo and even at 11psi of boost on the SC I have never felt as much low end torque on the SC as I do now w/only 5psi of boost on the TC!!! WITHOUT QUESTION the TC gives you alot more low end power and a hell of alot more torque than the SC. If you're a guy who likes to feel that "pin you to your seat", low-end power then the TC is for you. The SC does provide alot of HP but I'd say I noticed the power in higher gear (3rd mostly) and more so on the high end. Torque levels on the SC were always disappointing to me... you dont actually feel the power as much w/an SC which is why I decided to switch.
The stuff about the kits being harder to install on the 5th Gen than the 4th Gen is not true either. Remember, the engines and the engine bay setups are essentially the same for 4th & 5th Gen so install should really be just as easy for both... the only difference is the length of the piping... We 5th Gen guys have longer pipes Anyone who has had a chance to see the turbo install write-up for the PFI kit knows the instructions are the same! Hope this helps... Have a nice holiday!

Thank YOU Deac for clearing this up for the others

 

is there anything offered for my 03 6sd car yet?

 

So I guess nobody knows whether both a TC and SC can be used at the same time? Just curious...

 

Yes i have seen some drag cars have both. They are really hard to maintain and tune but it can be done. you just have to know your stuff!!

 

hmmmm...even SC starts to boost at very low rpm..but being on a linear boost curve, I only get 1 - 2 psi @ 2000 rpm at the most and I cant really feel anything under 3psi. I start to feel the SC after 4000 rpm where the boost is about 6psi. I have a 2.87 pulley

in this case, TC still has more advantage because at 3000, you already get all your need. The only downside of TC is that it takes a bit longer to reach 3000rpm from dead stop than SC.

 

if i said anything incorrect my bad, I felt my limited knowledge would give him a clue (was I that off???) BTW Deac's car rocks.
I've seen a few supercharger installs because I think must of us here go to the same mechanic, they all look clean, and everyone with the 3.0 vq seems to love em, I wish i got a chance to ride one : /. I'd love to compare the ride on one of those to my 2k2 6 speed. Anyone want to give their impressions?

 

turbomolar: ive seen that setup like that on a Nova be4 and it was basically a show car. The SC and turbos had to be running low boost and the engine built to hell to hold up. Basically all this setup will do is leave no room under the hood (he had no hood) and you will have no turbo lag. Its just for show, not too cost efficient on the street. Maybe 2-3 race cars have had this but its just a bit much and one of the either alone would probably work better, not to mention weigh less.

tonylittell: No such thing as of yet, just a matter of time however.

[maxi-overdose]: The SC has a slight advantage off the line, but consider that when your racing you will always be above 3500rpms were the turbo pulls extremly hard. Basically for things like emissions Id stick with the turbo since they dont go above 3K rpms anyway. The turbo will still be boosting at 2K same as the sc though at just 2-3 psi. 6 cylinders running 1 turbo leaves little room for lag, especially if your runnin a ceramic ball bearing turbo

 

I forget which car has this, but I remember reading that
some car with twin turbos uses a small one to spool up
right away, and a larger one to really kick in the power
slightly after the small one has done its job.

(Remember, smaller turbos spool up quicker but have less
max PSI, while larger turbos take longer to spool up but
are capable of a much higher PSI.)

Wouldn't that be nice?
=)

 

The stock 1.8t VW's will have them (sort of) They have and electric turbine which helps spool up the turbos til rpms climp then deactivate. That idea of twin turbo does somewhat work, but id still rather have two T4's in a supra rather then 1 t4 and one t3 that is why they created a hybrid T3/T4. You need to do a bit of research to understand it all...

 

The Audi S4 has this set up.

 

i think its called sequential turbos ..maybe wrong...

i think the supra has the same set-up
