where can i find info on the two engines offered in a fifth gen. which would be quicker a s/c 00-01 or a tubo 02-03?what are the differences/advantages of both?

 

well i think that a slightly modded 02-03 engine runs fairly close to a sc 00-01 motor, and if the 02-03 motor has a turbo on it, say a stage 2 thats out right now, thats pushing around 500 hp (not whp). so i would say that 02-03 with a turbo would be muuuuch quicker. correct me if im wrong, cause i might have missed somethin

I believe that turbochargers tend to be more efficient that superchargers, so I would have to say the larger 2k2 would be a lot quicker than a SC 2k.

We just need to find the room to twin turbocharge a 2k-2k1

 

and we need to find a way to fit the greddy twin turbo kit for the 350Z on the maxima VQ35

what is the stage ii turbo for the 3.5? the ssr engineering one?

 

hmmm.....manual SC'ed 2k/2k1 runs about 300+whp with a 3.125pulley. Even my auto 3.0 SC'ed dynoed at 270whp with 10psi of boost. I dont see how close it's going to run with a slightly mod'ed 3.5vq.

but....if you have an auto tranny 2k/2k1 SC'ed with a larger pulley, a modified 2k2 manual will be able to give it a good run. emax walked an auto SC'ed 2k with stock pulley (3.60) before.

 

I think we need to find a way to beef up the engine and tranny componet for the 3.0. Single turbo is able to bring the 3.0 over 400whp.

 

FWD- wrong wheel drive. I've owned plenty of high HP FWD cars.... all of em turbo. U want RWD for power delivery.

 

Shampoooo is better.........

 

I don't think so. Maybe an automatic w/ a large pulley but SCed 5sp will easily walk away from slightly modded 02.

 

a turbo 2k2 2k3 vs a SC 2k 2k1 would be fairly a good race the 2k 2k1 will pull right off the line but he 2k2 will catch up when the high rpm start to kick in, in the end i think the turbo would win though, cause all a SC really does is helps u get to your top speed much quicker as the turbo really does add extra power

 

not really, the turbo 2k2 will just pull on the sc 2k all the way

 

comparing a SC VQ30DE-K to a Turbocharged VQ35DE is like comparing a RB26DETT to a GA16DE. If anything traction issues with the Turbo 3.5L would give the 3.0L SCed an edge of the line, then the 3.5L would just smoke it like nothing. Every time I drive a 3.5L FWD Nissan- I35,MAX, Altima, I just don't feel the top end is there like on my K motor. Eighter way.... SR20DET would smoke both of these motors for less $$$

 

I smoked an old SE-R with an SR20DET easily. Very unimpressed. Of course I don't know what the Psi is or how built up it was but it was no doubt turboed.

 

Bone stock 6.5psi SR20DET in a B13 SE-R will run high 13s to mid 13s on slicks.... doubt it was runing right or driven right. I made 547WHP with a SR20 on stock internals code named 54C No VQ comes close...

 

Probably wasn't you that day.

 

Keep in mind the superchargers offered for the 3.0L build more boost as you get closer to redline, whereas the turbo'ed ones hit their full boost at much lower rpm's therefore you end up with muchhhhh more power (area) under the curve. So if you had two different maxima's, one supercharged, and one turboed running the same max PSI and say the drivers were the same skill level, and both cars were properly tuned... the turboed one should win.

 

I remotely enjoy people claiming you can achieve the effects of a forced induction with bolt ons.

That aside, my personal choice for a daily driver is a supecharger. Yes it produces less power, but is mroe reliable and generally provides smoother power delivery in general city conditions.

It really depends what you are after really.. track machine or just that extra push once in a while.

 

good number.

we havent seen any VQ closed to your no. because most of them are running on stock injectors or 370cc 300zxTT injectors (4th gen only). Aftermarket hi-flow injectors are still unavailable for 3.0 5th gen. There's only one 4th gen maxima running on 555cc nismo injectors.

SR20 has a lot more aftermarket support than VQ30.

 

Your car is faster but all i have to do is wait for that axel to break and i coast right by

 

That must be done.....then the turbo prices form SSR and Stillen (or whoever makes the other one) will go down.

 

3.0L vs. 3.5L, the 3.5 wins. Supercharger vs. turbocharger the turbo wins. Translation- the turbo 3.5 VQ wins easily. Has anyone heard of a little company called ATI Procharger? They developed a air to air intercooled centrifugal type supercharger for the 350Z which produces 370 WHP at 7 PSI. This kit seems way more adaptable for the 2k2-2k3's than a twin turbo. I am hoping I can get a Infiniti G35 Sedan 6MT and slap one of those kits on there. The rear wheel drive configuration should be much faster and easier to tune then our front wheel drivers. Also I hear HKS has a single Turbo set up for the 350Z that makes slightly more power than the twin turbo kit. That may also work on 3.5 Maximas.

 

Ofcourse 3.5 will win over 3.0 with same or no mods.

Bunch of local Cobra owners are running ATI Procharger pushing 500-700whp. Nasty stuff.

 

ummmm.....not true.....root type sc have similar boost curve to that of the turbo. I think you meant "centrifugal SC bs turbo, the turbo wins."? 'cause centrifugal SC has a linear boost curve.

 

Roots type blower do not have any top end power, they ten to restrict the intake manifold alot at higher RPM. The resonance effect in the intake manifold and piston speeds under higher RPMS make the roots blower un-efficient. Ever wonder why a GTP will get its doors blown off from a Roll by a 5spd 3.0L stock ? How bout a Supercharged Xterra ? They seem to have pretty decent powet till 5K RPM on the VG33E engine, but the VG33ER engine runs out of power by like 4K RPMs. Twin turbocharging is possible... just expenssive. Cost of 2 T28 turbos is going to be mega expensive. Some used Silvia T25s for like 200 for both might work good. Another thing ya gotta look at is CFM. of large turbo vs small turbo. I looked at my 3.0 closely- there is room for a twin turbo setup there- front has plenty of room, rear bank U will need to run the turbo over by the tranny and make a custom downpipe.... all it takes is time and effort. As long as putting larger injectors into a 5th gen- MSD 50lb top fead injectors. Make yourself a custom fuel rail-anyone whos been around SR20s,DSMs knows U can make ur own for cheap. I just designed a fuel and ignition Map for my friends SR20DE-T with Emanage, he says it runs super good- and he runs 50 lsbs MSDs.

 

the restriction of the root type SC is due to the excessive heat it generates. Since intercooling and aftercooling is not available for root type or screw type SC. the only method to correct it is to use water/alcohol injection.

but root SC have much better lowend than that of the turbo and centrifugal.

about the GTP vs 5spd 3.0 statement. the 5spd 3.0 is able to take the GTP because the GTP only comes in automatic tranny and a 6psi of SC boost. With a 4spd auto and a low boost, racing from a roll doesnt give this car any advantage. But again....from dead stop or with a smaller pulley, it is a different story.

When I raced my auto SC'ed maxima against other cars from a roll, I know I dont have much chance if I am rolling at 4th gear 75mph. Once I slam the pedal and downshift to 3rd, my rpm jumped to 4500 and my boost gauge read 6psi. That's not enough to pull the car. IMO, SC is better for manual shift cars where you can control your rpm.

I agree with you that the root/screw type sc does not have too much advantage over the top end. it is a characteristic this type of SC system - when all the boost is given at 2000 rpm, you can't expect to squeeze more boost out of the SC. Just like centrifugal SC and turbo have their disadvantage too.

 

you can't compare 3.0 SC vs. 3.5 turbo. The displacement of the 3.5 motor with turbo boost will destroy a 3.0 SC. Look at SSR's kit making past 350 hp on only 5 psi.

For 3.0 SC vs 3.0 Turbo... there are actually many threads and videos of this. SC builds boost relative to engine rpm, whereas Turbo makes full boost instanteously at xxx rpm

and btw, there are aftermarket injectors for the 3.0. Deac found out that the 3.5 maxima/z/g35 injectors fit with splicing, or you can run the PE 380cc injectors direct plug and play (IIRC)

 

the power enterprise one is the direct replacement of the stock injectors. I dont think anyone ever bought it from Japan. The only 4th gen maxima with nismo 555cc that I know of (I havent visited the SC/TC forum for a while) is Sx7r.

the RC injectors that Deac found are not a direct replacement. it needs to be modified.

 

What kind of Horsepower is Deac putting out these days? Isnt Deac over the 400 HP mark and close to 500. Didnt I see someone saying that a VQ engine couldnt make that kind of power?

 

I think the sky's the limit... nismo sells a high strength crankshaft that can handle 80% more power than the stock one. Who knows how far you can push the VQ? Probably farther than I'll ever need.

 

I love these threads, so informative.

 

i believe he was pushing the amount of hp at 10+ psi

whereas with the higher displacement of the vq35de, you could probably match his numbers relatively easily with slightly more than half the amount of boost.
