I am looking to buy either a 2001 SE or 2001 SE.

I like the way the 01 looks better than the 02.

I was wondering how much does the super charger cost for the 01? How much HP does it add??

Any ideas // suggestions for a good 2k max?

 

A stillen V2 SC is around $4000 .... the hp gain is probably around 80 hp at the crank..... but it depends on what size pulley you use.

 

Heh, well my vote is for the 2001 SE.

What are the actual pully sizes? I know of the 3.25" but can anyone explain exactly how they change psi and everything? or maybe if someone has a webpage to point me to. Thanks.

 

Get the 5spd 01 or a 6spd 02 (when it comes out). Do not get an auto if you want the most performance out of your Max especially if you are putting on an SC.

 

3.60" about 6.5 psi (stock)
3.48" about 7.5 psi (safe)
3.33" about 9 psi (on the brink of pusing it)
3.25" about 10 psi (pushing it)
3.125" about 11-12 psi (find a new tranny... QUICK!)
2.87" *BOOM*
2.67" *KABOOM*

 

smaller pullies make the blades in the s'c turn faster thus giving it more 'boost'. and you can go as small as you want as long as you take other precautions. like kev says, you need mad precautions for 3.25 and smaller. beefed up tranny (or new one all together), tranny cooler, oil cooler, optimized fuel map, etc. etc.

 

Mad precautions?!?!?!

beefed up tranny (or new one all together) --- VB, TCM, solenoid

tranny cooler --- yes

oil cooler --- I want

optimized fuel map --- . . . . . . . .

 

I never said it would be easy or cheap. but anything can be done with enough patience, persistence, and MONEY! and by optimized fuel map i meant completely tuning your computer for timing, fuel delivery and everything. i just was trying to shorten that. and i meant the mad precautions for smaller pullies than yours. i think the 3.25 can be run generally safe on a fairly stock motor...

 

You'll either need the UNICHIP or a stand alone ECU to change the timing and fuel maps.

3.25 on a stock motor is fine..... but the tranny.......... still sort of risky.

 

we should pool our knowledge and try and crack the Nissan ECU program....then reprogram it with our own stuff

 

Nauman's program = *BOOM*

 

but as long as it makes you fast, it's all good right? No implied warranty on longevity

 

. . . . . . . . .

 

It actually sounds like a good plan. Who here knows code, better yet, who knows what code Nissan uses for the 5th gen. I feel like we have some intelligent folks here at the .org, we should be able to pull is off. Make some nice cash in the process. Anyone know someone that actually has done any sort of reprogramming for any type of ECU? We need to do this.

 

Yes, but it's NOT that easy, DEFINITELY not cheap, and not worthwhile for anyone that can't sell LOTS of them. Especially, breaking Nissan code by uncompiling it then reverse Engineering it. You need serious hardware and LOTS of extra ECUs, because your going to break several. We would be better off putting PRESSURE on JWT, G-Force, or for a stand alone ECU Electromotive. JWT/G-Force have the resources and experience with Nissan ECUs. They just need some monetary persuasion(sp?) to get motivated and think its worth while. Their a little busy on Honduh boys and getting all their cash. I do think it's possible and the NEXT critical step in performance mods for our cars. Without it, I don't think we can gain much more from just bolt-ons.

 

You are absolutely correct. It needs to happen. Think of the wonders it could do for SC's, NOS, Rev limitters. I need to hit the lotto, FREE ECU's FOR ALL!

 

I know your tranny is auto, so how would one beef up a manual? I'm guessing a high performance clutch would benefit things? Just so I don't have to bug you guys about all this technical stuff, anyone able to refer me to a website that explains exactly what these different things do, and at what point and how much increased power one would have to add/beef up these components? thanks a lot

 

I know a bit of assembly for intel x86 and Motorola architectures..... but as to what processors the Nissan ECU uses?? It would take a lot of reverse engineering to take the machine opcodes, convert them back to assembly, and then go from there.... especially if we don't even know what language its written in....

 

It has got to be sort of a uniform code for automobiles. Well maybe among the imports. I am combing the internet now for forums or any sort of place where I might find anything useful. There has to be someone that knows what there doing. There is a chip for nearly every manufacturer/model sp? out there. But like Ice said, it would take alot of money and ECU's to mess with it. I think maybe we need to heist the computer the mechanics use to diagnoses your cars, Nissans of course, that would give us a start. And when people went in to get the TSB for the 5spd trannies they hooked it right up and loaded a patch, and presto.

 

People running high horsepowered Maximas recommend ACT street clutch...

 

When I had the TSB done for the 5spd ECU issue, the technician at the shop had to actually reprogram the ECU.
From what I gathered it is not a patch. Only 1 guy in the shop knew how to do it. If he knows how to do it.... then its possible.
The only downside is that if you screw up you need a new ECU. The shop said if the reprogramming didn't work that I would have needed to wait for a new ECU.

 

That's why I said we would need LOTS of ECUs. At least with the ECUs I mess with, the program is loaded into a VERY tempermental FLASH memory. If anything happens during the download or if a poorly written program over-runs memory capacity, the FLASH is screwed and you need a new part(actually a pair). The only problem is that the FLASH is not socket-mounted, but surface mounted, therefore the board is trash. I've broke a few at work and sometimes you can fix them, but after a few screw-ups they can't be reprogrammed.

"Uniform code for automobiles", yea right! Every company has their proprietary code and tools they use. They constantly change tools/code/methodology to the latest and "greatest" technology. Also, I've heard some companys are using software that "autogenerates" code. Now maybe that could be hacked and reverse-Engineered as long as you had the same platform, tools, and lots of money.

 

Are those my only choices?

 

umm no

tell me what you think I should buy??

I currently have a 97 maxima se and I want to get a new car.

 

Auto tranny's that is 5spds you will be fine.

 

so the final answer is????
