Is Nigels turbo kit better for a auto or is Hals turbo kit better?

 

You would not enjoy your car with that auto tranny. Trust me on that one. Id get a a 5 speed first before getting getting a turbo. 6PSI aint **** at least for me it was not had to bump it up to 9.5 PSI. Just sharing my opinion and at 8PSI bye bye auto tranny.

 

What if I get my auto fixed by level 10. How much boost can it take than?

 

there should be a sticky saying if you even want to think about turbo have 7k in your pocket before attempting it.. civic killer..just drive what you have and enjoy the car.

 

thanks (Ilovemymax)

 

but still how much psi can a level 10 tranny take? any thing will be helpfull.

 

Its not about the boost (psi) but rather how much fwhp/tq the car is making. A well tuned car could be putting 100hp more to the ground than a improperly tuned setup at the same psi. (well, maybe not quite that much but you get the idea)

 

There are exceptions to that, if you spend more time planning things, then the money needed is much, much lower. My personal setup is costing me less than half of that $7K number.

But Maxima turbos are kind of a new field right now so a lot of things have to be tried to find the right setup which isn't going to be cheap.

If someone is even considering a Hal kit though, they need to do a ton more research or they will spend way too much fixing things. Hal's kit is the reason there would even need to be a sticky about needing $7K before attempting it.

 

I know I didn't pay $7K for my setup.. I didn't really pay much at all now that I sit back and think about it. But what is great about my setup is that it takes the knowledge of all of those who have already attempted it and had problems and tried to avoid all of them.

You are going to have issues, small things, big things, smells, etc but that is just what you come to expect I guess. All in all, just wait another couple of months until the evolution-autodesign turbo kit is available.

 

evolution-autodesign is making a turbo kit for a maxima,cool what are the specs on it like (turbo size,piping,and lay out of the kit). is it a bolt on kit or is custom and how much will it cost? is it going to be better than the (CUSTOM MAXIMA) kit that just came out?

 

I run Evolution-Autodesign, specs will be up soon. As well as the layout and so on. I'm in the process of building prototype kit number 2 for my own car. Jason's kit worked out rather nicely.

I can't say whether it will be better or worse than any one else's kit. That's not really my place. When it's done, we'll let the results play out.

For pics, check out http://www.evolution-autodesign.com/projects/max2.htm

That was the first kit we did. My car is an auto, so that is why we are building prototype number 2 as obviously a manual kit won't work on an auto. The layout would be similar to what you see in those pics.

 

(shadow) What are the pipes made out of? Will they rust?

 

Pipes are standard steel, but they would be powdercoated and the feed pipe and down pipe would be ceramic coated. So I would not worry about rust too much.

It's too much hassle to work with aluminum since it's so expensive and hard to work with. Same goes for stainless.

 

Thanks for the help!!!!!!! try to send me a e-mail when that auto kit is done

 

No problem, give me a couple of weeks to get it done and make it pretty

 

Thanks

 

one thing that has been driving me up a wall is there are so many turbo kits out there IS (CUSTOM MAXIMA)'S KIT GOOD OR BAD?????? Peolpe say that it blows there engine and I am thanking about buying it so should I or not????????

 

I 2nd that comment, just get a 5-spd swap and then do some planning. The Maxima auto trannies are weak, no matter how much the internals are strengthened. There is no such thing as a bullet-proof tranny. Level 10 is weak too, and don't even think about getting those worthless VB upgrades, just get the manual swap.

 

There right

Dont waste your money on turboing a AUTO, the auto tranny in any gen is weak, Even with a stage 10 Tranny you wont be able to boost over 7 w/o blowing your tranny, it just slips too much, I did research on it because I my self am an AUTO, Use your money for a 5spd conversion, or trade it in for a 5spd and turbo that.

 

100whp.....my god! that's a lot. how many psi of boost are we talking about here?

just to clarify. in my case, both runs were untuned, one lean, one rich. my peak boost is 10psi from supercharger.

lean run with greddy cat-back : 261whp and 13:1 AFR
rich run with stock cat-back : 267whp and <10:1 AFR (off the chart)


so if I get the AFR to 11:1, I will probably get a 280whp the most.

 

Hey Bags, where's your opinion on this?

"Don't waste your money on a worthless VB mod", "auto transmission can't hold more than 7psi without blowing up" ..

How many of you guys saying this even HAVE boost on your autos?

CiViC KiLLeR -- Pretty much any turbo kit you get is going to be generally the same as long as the bugs are worked out. A stock transmission with nothing done to it probably won't last longer than afew months. A transmission with an upgraded VB & cooler will most likely live significantly longer, but as it was previously stated, running 10PSI of boost (on a turbo) will shorten the life of your transmission SIGNIFICANTLY.

I plan on building a custom kit, or getting Shadow/thebigsadler's somewhere down the road. When I do it, I'll be keeping the auto I have (vb / coolered) and aiming for around 350fwhp. I will have money set aside for the 5 speed swap however, because with the amount of power a turbo can put down, it WILL break eventually. If you read most peoples experiences with Level 10, you'll find that in the long run, you're better with a 5 speed.

 

Ah, the .org bandwagon (autos suck, must have MEVI, CAI's rule, no wait, they suck, Frankencar rules, and on and on). How many times has there been a consensus here that something can't be done, or won't work and then it gets proven wrong. Who would have thought we would ever have turbos? Or that it would even be this easy? 2 years back, everyone agreed that you couldn't turbocharge a Maxima because it would just cost too much and be difficult to do. And back then, people thought that if you broke 300 whp, the motor would go, and a little while before that, there was no way anyone would ever run 11's in a Maxima. If we had listened to those naysayers, then there would have never been any advances in Maxima tuning.

Gotta love it when someone definitively states that an automatic won't hold up to more than 7psi of boost. 7psi from the SC is way different than 7 psi from a turbo and 7 psi is going to have a huge variance just between different types of turbos. So if I set my boost controler to 7 psi, I'm guaranteed that my tranny will be ok? Without knowing the type of turbo, the setup or anything else, there are no hard numbers. Yes, Corey blew up his tranny at 7 psi, Kirk blew his at 8-10 psi, but that now means that all autos will go at 7 psi? Kirk drives his car, um how do we say, rather aggressively. Think maybe that had something to do with it? And since unfortunately, Corey's motor let go at 7 psi also, does that mean the Maxima motor won't take more than 7 psi?

Just shows the ignorance of those who "did their research" Of course a Level10 rebuild doesn't help. Level10 is basically a scam shop, they built a couple of decent trannies and got a rep for performance trannies. But it's been proven time and time again that a lot of times, their "performance" rebuilds actually use stock parts. They just lie about it.

Yes, the auto has problems. It won't hold insane amounts of power. But how many Maximas have that much power? I'll admit that the auto will eventually fail under boost or lots of nitrous. But I know of a lot of autos that have been running for a long time on boost. My car is at 100K and the tranny is fine, it was boosted for 20K.

The 5 spd. is stronger, but do a search and see how many 5 spds. have blown up. It's not a small number either. Maximas have weak transmissions period relative to the amount of power the motor can make. The only reason I would say to convert to a 5 spd. is performance. It's got much better gear ratios. But telling someone that they have to get a 5 spd. if they get a turbo isn't correct.

Myself personally, I will see just how much power the auto will take. We're going to keep upping the boost and nitrous and see what happens at the track. Look at JimE's times, he's running an insane amount of nitrous on a stock auto and runs 12.1's. He should be the proof that autos aren't all that bad.

 

If you drive like an idiot, you can blow your auto/manual tranny with no boost.

 

Yup, just remember people. Don't do any burnouts on pillows

Some of you will know who I'm referring to. Wonder if he's done that with the C5 yet.

 

Wow. Nice post Shadow I don't know 100% about the level 10 stuff but I'd be inclined to believe it when I see their sucess rates.

Definately agreed on how you drive. If you're flooring it at every light and spinning the wheels until 3rd gear, your going to have transmission problems -- 5speed OR auto hehe. I'm not even going to get into pillow burnouts or neutral drops.

 

Please, I wonder if he got the C5 back together after last winter.....

 

Been there, done that, and like I said, no matter what you do to the auto tranny it'll still be too weak to hold boost. The tranny will need a rebuild sooner than you'd think.

 

Level 10's tranny isn't jack compared to the NRH custom built auto...

It's on my list of things to get before I get turboed.

 

Can I see pics of your boost setup and your auto transmission? I'm not that inclined to believe you're talking from experience after you stated a y-pipe adds 6fwhp.

 

No problem, smart a$$. And 6fwhp on a N/A car, not a boosted one.
You see the Permacool oil cooler and Hayden tranny cooler in the front?!

 

Nice pancake

If you got 6fwhp from a y-pipe N/A, something is/was seriously wrong with your car. The majority of people on the .org get 12-18, myself included. If you treated your car as poorly as you did your transmission, it's highly possible THAT's the reason behind you only getting 6fwhp.

 

Thanks, the pancake is much better than sticking your filter in the wheel well where the stock fog light blocks air. Do you and the rest of your boys have dyno slips showing this 12-18fwhp? Like I said, boosting an auto with about 130K miles is asking for trouble, which I've learned my lesson. I see your thinking about selling your SC, maybe your actually listening to me.

 

I took my stock fog lights out for that exact reason, but thanks. Some people find the extra 1psi helpful, and cheap.

Here's a link to a 18fwhp gain peak, 29fwhp at 6000-6200:

As for selling the SC, that will be replaced with a turbo, on an AUTO TRANSMISSION. Feel free to flame. Some of us take better care of our autos than others

 

It is asking for trouble...but then again pushing the horsepower on any car w/ any tranny 100+ over stock along w/ tons of low end torque isn't exactly asking to improve its longevity. Automatic or manual you can still destroy a transmission with the kinds of power the VQ + forced induction is capable of.

Now, on a stock car I would say it's best to trade it in for a manual model before starting any heavy performance work but apparently it's very cheap to perform the swap on a Maxima. That's a factor in all those who have already modified their cars a good deal. But what exactly will the harm in boosting an auto car until it blows up and then the person can decide to go manual or to another cheap auto. Same swap, car runs for a while w/o the additional investment, and used auto trannies aren't exactly worth a lot even if they haven't been used in FI setups.

Personally, the control of the 5spd is much better but some people like to drive w/o working out their left leg all the time. Putting down the extra power to the wheels w/ the manual is definitely nice but remember several of the fastest Maximas out there are nitrous autos w/o no actual reinforcements. W/ the kinds of torque nitrous puts down in the low end, I would expect that to be the highest stress test of any auto Max tranny. As I build Shadow's turbo setup, I do question how long until we reach the breaking point but there's no sense in swapping out until we reach that level of power.

 

There isn't any. That's my plan

Shadow's setup should see afew months if his transmission isn't already slipping and he keeps it under 10psi (with moderate driving). I'm hoping to get at least 3 months out of mine after I turbo it.

 

Who says anything about keeping it under 10psi?

It may stay mild for about a week until we get it tuned and all the fuel controls in. Then I get the feeling Shadow may end up pushing the envelope a bit if he goes w/ the fuel setup he wants to. He's always been a bit boost happy. He did keep buying pulleys for his V2...just too lazy to ever install them w/ the stripped out bolt. Being able to up boost w/ just a controller should remedy that.

 

Yea uh, that's a 5-spd with a intake installed, wheres the dyno slip of an auto with just a y-pipe being tested on the same day?

 

I haven't seen very many auto dynos. If you want to throw some numbers around though:

a) 178fwhp with a y-pipe
b) 159fwhp without y-pipe

With an extra 0.07% drivetrain loss (17% -> 25% for the automagic), You've got 148->166.

Next you're going to be telling me the initial 4fwhp gain from a cone filter equates to a an extra 12hp with a y-pipe so that your little theory actually works Get off it moron, if you gain 18fwhp with a 5speed, you're going to get at LEAST 10-12 with an auto.

 

When it comes to an auto , its all how the auto is built. An auto can be built so that it never goes out of its power band, like mine. It can be built so that the loss is almost identical to the loss of a 5 spd, like mine. It can also be made to handle 350 to 400 fwhp with no problems, like mine. It can also outshift any 5spd, and not miss shifts. It also can be built to withstand boost and have a 2 year warranty, Like mine!!!! Hmmmmm the reliabilty of the auto just surpassed that of the 5 spd swap. The big thing here really is that if you want to keep your auto you can. You just have to pay for what you want. The avg 5 sp swap is being done for about 1500 total. Whereas a built auto tranny will run you about 3500 which includes 100% posi traction and a high stall torque converter and twin lock up plates. If someone did a 5spd swap and added those lil extras, thent they would spend about 2500. total. It all comes down to the way you like to drive, and how big your pocketbook is. I say if you have the money and like your auto, then go for it!!! Otherwise, be like everyone else and go the same route as the masses!!!

Yes my engine blew at 6psi but right now the only thing we can come up with on why is improper tuning. We will all see soon. My engine is almost done. I will prove that an auto will handle 350+hp as a daily driver.

 

I want a auto just like REDMAX has in his car. Like he said I want a auto that will handle 400hp and i have 3500 to spind on a auto. auto's kick a** in my book. one last thing what is the final drive in your auto (REDMAX).
