Supercharger

[rxm6]

hey guys, looking for a supercharger. What are you guys running? What do you recommend? Where can I get it or piece it together? Thanks.

Also, probably going to need a better fuel pump right? What should I get there?

[jltibbs]

i would recommend the vortec SC. if you search aftermaket fuel pump, you will come up with a link that youre not allowed to view. i got to it not too long ago and they were charging $85 shipped for a walbro 255.

You have to get a supercharger bracket kit first to mount the charger to the maxima. Stillen used to make them but there are replicas out there that you can get out there cheaper than Stillen.

And yea, you can pretty much get any Vortec S/C blower. That other unprofessional site Maxima.org has a post about all the info and bracket kit you need. The kit is kinda high in price but still cheaper than Stillen was and it comes with mostly everything needed except the S/C...I think it is in group Deals section... ask if you like the linky and I will find it...

You will see an 70HP increase(260HP) with this charger to the crank so aprox you will see only about 221-225HP to the wheels. Which is still pretty good but It depends if the price of about under 3 grand is worth it too you. Not to mention as jtibbs mentioned you might wanna get a high flow fuel pump and a few other parts.

O and here is an example(imo).. of the S/C upgrade...You really won't get beating those crappy(lol) Neon SRT-4s(260HP) just yet, as they have the about same whp after your S/C but they also got the power of the turbo and a shorter geared transmission mixed with a 200lbs lighter car...but you may be able to keep up with one! and beat mostly anything on the road right now in the same league

0o0o lucky... you have VLSD... You may have some edge there... After a poly-mount upgrade as well so you don't get that annoying wheel hop I30s and Maximas are known for.

Wheel hop? poly mount upgrade? do explain.

And only a 30hp increase to the wheels? doesn't seem worth the money. What I need is torque.

[hsckris]

umm... your car probably doesn't have 190WHP right now, being a 98. i believe the 98 had the 3.0 with 190hp at the crank, not at the wheels.

wheel hop isn't good. heres a definition i found, explains it as well as i could "An undesirable suspension characteristic in which a wheel (or several) moves up and down so violently that it actually leaves the ground." 1

poly mounts refers to your engine and transmission mounts, a poly mount would be an upgrade over stock and increase the stiffness to reduce flex & or movement during drivetrain load.

i would recommend also getting high flow injectors and certainly an adjustable fuel pressure regulator. you'd probably also want to upgrade the spark (i'm not sure what is available) and i'd go ahead and do header/ypipe/exhaust and maybe even a few other things if i was going to go s/c. maybe even a JWT ecu (?)

I've noticed this, freaked the hell out of me as I was taking a turn. Won't a suspension upgrade. i.e stiffer shocks and stiffer springs solve this problem to some extent or fully?

umm, nobody said his car or my car had 190WHP... it is 160-165whp...

so were did you get that from?

[A.Tech]

Yes... Poly mounts and suspension upgrade will stop, if not improve it greatly...

I recommend some Tein coilover basics! if you want some of the best coilovers...

or H&K springs matched with some Tokico Illumina... if you want a stiffer setup... you can get some Eibachs!

he said it... he said he didn't think it'd be worth it for a 30whp gain. you said he'd get up to 220ish whp, so i assumed, using basic math, that he was assuming he had 190WHP instead of crank HP.

yeah my bad. I was under the impression the 3.0 had 190whp not at the crank, I made a mistake. So then that means if it only has 165whp that means at most I'm going to get only 200whp out of a supercharger? What about building the engine? Stronger and lighter everything. Can I get 250whp out of this engine? I think if i could do that with a charger, I would be happy. Without a charger could I get 200whp?

[hsckris]

i'm not sure what is available as far as getting deeper into the engine and everything... i'm sure somebody is and will post up.

there was a guy awhile back with a 95 maxima turbo running 12s in the 1/4. i'm not sure what all he had done.

my question is: what is your goal for this car? i mean, you may want to consider other things depending on your goal, like getting a different car or perhaps reducing weight in addition to power adders/bolt-ons.

thats a really good question I'm not looking for 1/4 mile king. I would buy a different car with rwd for that. I'm more looking for everyday performance. Where I live is peppered with mountain and back-country roads and I drive them everyday to get to work. So handling is the most important to me and I know that the i30 can handle well when properly set up. So that isn't worrying me. What I want in terms of power is to come out of a turn a be able to punch it and get somewhere. Right now I'm happy with the 205lbs:ft of torque that the VQ30DE pumps out. But I want more. I really like the car and I'd rather drive a bigger car and make it perform rather than getting a 240 or a Z and calling it a day.

To tell the truth, I haven't thought of weight reduction until you mentioned it. I've seen carbon fibre hoods for the maxima but none for the i30. And I'm not a fan of the unpainted look, so if and when I do that, I would have to get it painted to match. But, what else could I do for weight redux? Keep in mind, I want to retain the functionality of the car. So things like removing the back seat and spare tire are not as feasible as they were in other car's I've worked on. Also wouldn't that mess with the weight ratio: Front vs. Rear? No, I think any weight reduction I do should be at the front, like a hood and lightened engine parts, and all the rest of the car should be left untouched. This might even out weight distribution in the end.

But here I am rambling on. Sorry.

You're not going to make the engine any lighter, it's already made out of aluminum. If you want increased power, get cams, intake, exhaust, and underdrive pulley. Or you could always drop in a 3.5L.

That would be the HLH Maxima. There are a bunch of videos of it in the video sticky on here.
