Hey guys, I'm new to the forum and relatively new to the whole car tuning scene. I own one of the 50th AE 300z's, and I know the engine is limited to 137. I do also know that it can go a decent amount faster. Is there any way to remove that Gov, or am I stuck with it unless I drop a new motor and tranny?

its an electronic gov, you wouldn't never be required to change the engine or transmission to bypass it.
Kimbro Slice: (2010-10-10 23:04:45)
gotcha. So what would be required to remove it?

Cut the purple wire…

Yep it's that simple, but as you are new to the car scene and assuming the suspension is stock, why would you need to exceed 137? At that point it seems like just a bad idea.

It seems I can never remember the difference between RPM and SPEED
and the dang pictures are on my site,

I've been going 137 on a freeway in the middle of BFE with a friend in an LS1 swapped Z28, and he pulled away cause i was getting stopped at 137. i wont be going over 137 much, but I would like to have it unrestricted just in case. And i'm running with the MacPherson struts, so it should be able to hold fine for short amounts of time at a higher speed

Feel free to kill yourself by exceeding the safety limits in a car with worn suspension. It would be a shame to wreck a good AE though.
Kimbro Slice: (2010-10-11 01:06:22)
Didn't ask you to be a dick about it, I was just curious in how to do it
Richard_85ZXT: (2010-10-11 01:08:31)
I'll just say that make sure your suspension is at least up to stock specs, in stock form the Z31 can do 137 easily enough but with a little wear it can start to get unstable. Exceeding 137 it will become more noticeable so as you look into upgrades I'd start there. I'm not a fan of MacPherson, struts, I think they are acceptable for daily driving but mainly intended to save space and cost. If I wanted to street race I'd find a turbo Z that's not a limited production, but ultimately it's your car so I'll make any suggestions I can to maybe prevent that from happening while you do what you decide to do.
Kimbro Slice: (2010-10-11 01:10:49)
Thanks man, i'm still figuring out what i want to do to the car exactly.
Richard_85ZXT: (2010-10-11 01:34:05)
since I have a general idea of what your uses are, what do you have done now? There are a few members that street race that may be able to help.
ZFast88Z: (2010-10-11 01:51:54)
Wait, your saying an LS1 Camaro was pulling on you because you still have the speed limiter? LOL
You should probably leave the speed limiter in place.
Cut the purple wire, and put it on a switch. Preferably the horn button on your steering wheel. Dont forget to scream NAWWWWZZZZZ when you push it.

I did 145 on a stock NA suspension with worn front struts…wasnt fun at all. Did 140 on Bilsteins with stock NA springs, it felt fairly stable, havent gone fast with the Z3Rs but the car feels better a lot speeds no doubt.
Kimbro Slice: (2010-10-11 19:04:53)
I have a cold air thrown on, magnaflow catback exhaust, and im getting a bov on right now. Since not many companies make parts for these cars anymore, i'm still lost and not exactly sure on what to do with the car. I do want to get some lowering springs and more suspension work done first because it is a 27 year old car
Richard_85ZXT: (2010-10-11 19:41:26)
Coilovers are becoming more and more popular but are not exactly a direct bolt in, but just using upgraded springs (suspension techniques/eibach/Z3R's), upgrade the shocks (Koni/Illuminas/Bilsteins) and poly bushings throughout is what most people do. It will make for a stiff ride though, I'd recommend stiffer sway bars rather than springs so it'll be similar handling but a softer ride. Z31parts.com is awesome, for clutch there are a few options but a recent favorite is south bend clutch. EP racing has tons of possibilities if you are willing to pay, Also more common lately is the VG33ET, that should be be a good start to get you going, as you get going I'm sure you'll have questions. Brake upgrade would be something I'd suggest as well, but search around the fourms here and you'll find PLENTY.

Yeah man, I've been reading around quite a bit the past few days. I'll just need to determine what exactly i want to do first, and then just go with it. The main thing for me right now is money, haha. Once i get some cash i can really start building into the car.
Richard_85ZXT: (2010-10-11 21:34:24)
well....that's most of us. I've got my builds decided for the most part but money is always the problem, it's the common Z31 owner curse.

I fear the worst for your 50th :-(
A race against your buddy isn't worth your life. Doing that speed, on or off the track, without at least a helmet in a 1984 300zx on Mcphearsons, is a recipe for disaster.
Kimbro Slice: (2010-10-29 19:15:59)
Oh we weren't racing, it was in July on the way to Import Alliance held at Nashville Superspeedway. My buddy in his Z28 sped up to catch this mustang in front and they started pulling away so i wanted to stay with em. I'm not racing or anything for now, I wanna get stuff replaced first. I'm also in the process of purchasing an S13 shell to use as a drift car, but yeah.
