I have a auto 1998 I30 and im getting a turbo this summer. Is it worth it to get the manual conversion or just stick with the auto. I do not want to change that many things over with my engine if it's not even gonna make a big difference, and I see on maxima.org alot of people with auto turbo's and I30's .

 

this should answer most of your questions

Someone correct me if I am wrong but, from my understanding, auto turbos are faster than stick shift turbos. This is because when you shift in a stick shift, you need to take your foot off the gas. There is this guy on the Supra forum who has a stick TT and an auto TT. He says his auto wins hands down everytime at the track.

 

no....they can be faster, but in genreal usually aren't(stock tranny v. stock tranny) if HP is same, 5spd with decent driver will win 99% of the time

 

If you're good, you don't let all the way off the gas when you shift. Just enough to rev match the gear you're going into.

 

built auto > manual
it will maintain full boost through a shift, not to mention shifting faster anyways. also you can build boost at the line w/out twostep or antilag (which is possible in a manual , just not easy and terrible on the clutch) and typically more consistent & perfect launches

now where you can find a good built auto tranny for the maxima? Don't know. Someone needs to talk SP into making a SP400 for the max haha

for fun driving, manual will always reign!

 

thats right because once you press the clutch you lose boost.
a auto wont lose boost.. but it all depends on the driver and what is actually in both cars....

 

I never thought about it in the context of shifting before, but supercharger boost is engine rpm dependent, turbo boost is throttle position dependent. So you don't lose boost when you manually shift a SC'd car.

 

the blow off valve isnt just to make a cool sound its to help reduce the turbo despool between shifts

and of course i agree with the fact that a $$$well biult auto$$$ will beat a manual in a high hp car but i would never drive it because it would be

SO DA$M BORING TO DRIVE

 

Manual hands down until someone ***** a bullit proof tranny for our cars. People that play alot here on the org are manuals. What I mean by play is that they hang out on private property etc..making racing videos at night. Its true an auto vehicle has the advantage. I dont think that will apply for a maxima. Why would you want that heavy clunk of metal in the car. Any of you ever try to pick up an auto tranny ? that **** is heavy! very heavy. I prefer a manual tranny with a Quaife or LSD over an auto tranny any day.

 

Auto would own a 5spd given the right setup (TC stall speed, gear ratio). Once you pass the 300whp mark the auto definitly has the edge.

 

Doesn't the throttleplate stay open in the auto maximas? I know it closes every time the transmission shifts on a supra. Wouldn't that keep the boost up?

 

if you hold the skinny pedal on the floor the throtle plate is open so yes but you can also hold thethrottle plate open all the time on a manual to i believe its called power shifting

 

Your So Right

 

JUST WHAT IVE BEEN TRYING TO SAY ALL ALONG.. THANK YOU WELL PUT...

 

Yeah, I've always felt that arguments that agreed with mine were well put, too.

 

id like to see someone who knows HOW TO SHIFT A MANUAL AT THE TRACK and there are a few here that do, to run there car with the stick and then put a biult auto in and run it with that. i bet the numbers would be so close that it would be cheaper to add more hp to the car and keep it a stick than to biult a $3000 auto

i mean how much extra power would the manual need to make up for the slightly slower shifting probobly only 20 or 30 maybe even less than that

 

no its the other way around.. it is us autotragic drivers that have to play catch up.. i think we have to spend more money to keep up with a five speed, but once we do... watch out..

 

NRH has a pretty stout custom auto for under $4K...with LSD.

 

who is nrh?

 

You need to talk to JaimeCBR900 - he knows ALL about torqing up auto trannys

 

I believe he used NRH for parts as well. NRH is in Jessup, MD...build high quality, high performance transmissions. Do a search here on the .org (if you can) and look for their name. I might have a site saved somewhere about them. If so, I'll post the info...

(Conrad283) levelten trans SUCK. Thay maybe a little stronger than stock but not much. The beat place that bulletproofs trans is NRH thay are the best for a maxima.

 

i had an built auto in my old i30 (3100 stall, posi, stage 3 vb mod, etc, ect) but i sold it. anyways i raced him from a stop he got owned bad. if you are performance oriented 5-speed baby. if not go auto. whatever you do just go fast.............................................. ..............................



















5 speed all the way!!!!

 

I have an NRH Auto Tranny and will be boosting over 300whp by tomorrow and less just say this thing shifts effortlessly!!!! It Is Da Bomb!!!! The only down fall is the 3500 to 3700. price tag. It has full 100% posi Traction! The best thing is Rob warranties the tranny knowing full well that the thing is going to be beat on. as a matter of fact he wants you to beat on it.




AUTO TRANNIES OWN STICK ANYDAY!!!!!!

 

Silly question, but if I had a spare auto, I could just send it to Rob at NRH? I know shipping would cost, but that's no huge deal. I mean, he doesn't need the car for any of his work does he? And what is turnaround time?

 

I'll definently vouch for Coreys tranny...after riding and test driving the car after this weekends 3 day re/install extravaganza I will say NRH auo trannys OWN!!! the 1-2 shift is simply flawless, smooth and quick as a knife through butter...I have a few videos, but need a host tonight should be fun

 

Turn around is usually 2 weeks on trannies and no he doesnt need the car for anything

Addae we are confirmed for 6pm tomorrow

 

Yeah, what he said. The price more than justifies what you get (both physically, and in the form of his warranty). This is the ultimate auto transmission for our Maximas...

 

I get mine in the next week.
