transmission
 

I have a 1.6L 5spd and i need a new tranny... can i buy a 1.8L or do i need to modify the bell housing? is the bell housing bolted to or part of of the tranny? is it a direct fit? what do i have to do to drop in a 1.8L 5 spd or a 6 spd?

Can you do a search?

i believe the 90-97 trannys are all the same correct me if i am wrong?

They're all the same, different speedo gears for some years maybe. Otherwise it should be fine.

id like a taller gear ratio... my car goes through first in less then 1 second.. turbo hits at 3000rpm and goes right over to 7300rpm

Then you need a different rearend, not a different transmission.

well for starters i need a new transmission, the car wont go into reverse (54k miles) and sticks going into 3rd so i cant power shift into third, and first gear is very short

Cause your granny shifting and not double clutching like you should.

ok vin diesel.... lol you amost had me? you NEVER had me! You NEVER had your car!

+ban

why is everyone obsessed with banning? what did i do? quote the next line in a movie?

dude, the 5 speeds are god for 300 hp, and the 6 speeds will bolt up to yor car, and handle alittle more power. You need a different rear end ratio to solve the shitty gearing for first gear.

Do a motherfucking

does anyone else have this problem? first gear is like one second long? but all other gears are great? short but great?

Then start is 2nd gear and quit your whining. We all have a short first gear. If you don't like it then get a taller rear end. Or you can spend a small fortune on the Quaife gearset.

i would start in first but i also slalom(smaller version of autocross) and the idea is to stay in one gear... first... and it would just be nice to make first gear just a little longer, the rest could stay the same

Get a taller ring and pinion. You probably have 4.30s right now, get 3.9s.

do you happen to know how much that would run me?

no, but i bet a SEARCH would bring up all kinds of information. Believe it or not, you're not the first to think of this.

ive used the stupid search button every time you guys say, i read through all of the forums listed as best i can and guess what? THEY DONT ANSWER MY QUESTIONS SO I ASK THEM HERE!!! if you dont like it, then dont answer the question!!!!

took me THIRTY SECONDS

ban.

sorry.... but, LOLOLOLOLOLOLOL!!!!!!!!!!!!!!!!!!

Wow, are there a lot of folks on this forum warm and welcoming like this? I've been in the miata scene since '91 and have had various forums of a turbo since '96 but... am new to this forum. Yes, I agree on the search ethic but lighten up a little. Not everyone has all day to look for an answer to a question that is buried somewhere. BTW, some of the sacred forum info from dated posts aren't exactly current anymore so it doesn't hurt to ask some of the same questions. I used to be sensitive to reading the same questions on other forums, but it's the nature of it. I got over it. A reply like this one is just is brilliant. Feel proud.

btw, your search didnt give wht i wanted, just so happens that i clicked on braineacks name and red his pages and got an answer i was looking for, but not price...i need a 1.8L rear end... you didnt come up with that one in your search though did you?

ban.



ps, thanks leebo.. everyone is always trying to ban people... i get sick of it so if someone says ban me, i write back with ban to them.

1.8 Diff swaps can be had for $200-$600+ it seems depending on how good you are at shopping. If it doesn't have the ring and pinion you want they can be had 2nd hand or new as well. Price will vary on those, i've seen 3.9 gears for $150 all the way up to $350.

so heres a quick question for you... in 5th... how much rpm loss is there?
I dont want to lose too much because the track is 3,4,5... is there much of a difference in the 4.1 and the 3.9? or even is there a big dif between the 4.3 and the 4.1? noticable?

Like that's my problem? OHH SEARCHING THE FORUM IS TOO HARD ILL JUST ASK THE SAME STUPID QUESTIONS OVER AND OVER AGAIN. Even I do a goddamn search every time I have a question, and then I take the info I get from that search and post a thread - with the info I've already gathered - and ask for opinions on my particular setup. If this guy had come into the thread saying "hey guyz i wanna swap my R&P for a lower one, but i dunno how much lower to go, how does everyone like their 3.9/3.6" he would have gotten a bunch of good responses and this would have been a nice thread where everyone can compare their shit.

This is not a polite forum, and we (or at least I) don't tolerate stupid shit like this. There is so much info and so much work put into the various FAQs, and so much can be found with a few minutes of searching, that I have absolutely no tolerance for people who think the entire forum is their question and answer service. You wanna solicit opinions about a setup, or share your stuff, or ask questions about a new product, that's fine, but asking shit that has been covered over and over and over and over again is annoying as fuck, and on this forum, you get called out for it.

i dont mean to point out the obvious, but if you dont want to answer the question, no one is forcing you to... and this thread started as me asking if the bell housings were the same on the 1.6 and the 1.8 and for the 6spd. then it turned into other things, such as a whole new rear end, then we started talking about different ratios, would you like me to start a new one?

Yeah that annoying, just like reading your profanity. Don't worry, I'm done posting to this thread. Not worth it. This is off topic anyway.

savington, go to my new thread since your annoyed with the title of this one

Please don't start a new thread.
On the track you will really appreciate the 3.9, i think total RPM drop in 5th is around 300 RPM just off the top of my head, might be a little more or less. Could be closer to 200 RPM.
Here are some good websites to look at:

wow thats nothing, how about with the 3.6? from the 4.3?

I know there are more accurate numbers somewhere, go read that thread i posted a link to in your RP thread. (And here)

Well , there is the problem right there. You really wonder why you're having problems with your car?

Seriously though, 100 posts in a month? :bang:

Newb, you need to spend more time reading about our cars. Your horing up our forum with lots of stupid simple questions that have been answered so many times. I guarantee you the anwer to your questions can be answered with a simple search.

snaps to cjernigan for the patience we all wish we had :bigtu:

FYI: the car is NOT for street use, its street legal right now, but not much longer. on the track, its all about getting the quickest time, im not talking about shifting without a clutch, im talking about fast shifting. ps... i think my clutch is on the way out the door as well

hey ------, we all have better things to than answer your stupid fucking question...like fingerbang our sphincters. Your total inability to do anything for yourself is just about the most excrutiating thing I've ever been through in my life. I'd rather watch competitive elephant ejaculation than read your bullshit threads. Use the fucking search button, and stop posting immediately or you'll have to deal with my wrath. You do not want to piss me off. Do not let it happen again.

you're probably one of those hot-shot poseurs on the track who fucking cries in his sleep and runs his mouth while I post up faster times and go home to bang my supermodel girlfriend.

I don't know a goddamn thing -
But it seems reasonable to just calculate the difference in rear end ratios as a percentage (3.9/4.1) and apply that to the RPM. 3.9 is 95% of 4.1, right? Multiply that by 7k rpm = 6658. That's a drop of 342. Trans gears stay the same so they have zero impact. Linear = easy.

i wish phillip was still here

actually to be completely honest i dont say shit at the track, i have this race car strictly as a family hobby, i love racing cars and this is my latest setup, i had a 93 probe gt with a 75 shot of nitrous and a shit load of other things, it weighed next to nothing, i ended up droping in a klze into it, do some cam work made 275 with the nitrous at the wheels

Sorry, this ain't M.net bitch. You want everyone singing kumbya, go there! And yes, retards welcome at M.Net

Really, if Hustler is dogging you, that speaks volumes.... We used to call Hustler, Timmmmyyyyy! Now, I think we have a new Timmmmyyyyy, and it's 1fastmiata.

Dude this is so fucking simple it is retarded. If you have enough time to make 100 posts in a month you have enough time to read the forum. If you don't want to read the forum the GTFO. We do not mind helping people but god damn people have to help themselves a little as well. This is simple shit if you have had a miata since 91 and do not know this shit then you must not do much work on it yourself becouse your research is directly proportional to the amount of effort you will need to put in to the project. +1 for ban on this wine and cheese check book racer. Leebo 90+% of the info in the dated posts is fuly accurate, even if otherways have come about, in recent years the old ways still work quite fine.

i had a 94 pgt last that i turboed. wheel spin in 4th FTL!

No i havent I have ahd it for 2 years, and for all 2 years after every race i have to do something to my turbo. i have installed a link ecu, i am now boosting 18psi instead of 6psi, installed larger injectors, larger intercooler, o-ringed the head, gutted(not done yet) the interior, and have been trying to fix my cooling problem. this forum has givin me info on how to cool down my car (thank you paul!), has givin me info that i need to buy a godspeed rad and slimline fans that pull 1600 cfm+ each, i should probably buy or modify a hood because apperantly my raised hood is being conter-productive, i need to throw away my link ecu and buy a megasquirt..

the reason why i have 100 posts is because they are either all within an hour, or i turn on my computer, find that someone has replied to my thread, and i go to that thread answer them, wait a little to see if anyone responds and then i shut off the computer, while im waiting I USE THE SEARCH BUTTON AND READ WHAT I CAN, so STOP telling me i dont, because i do and i have learned alot by using it and HAVE NOT STARTED A NEW THREAD BECAUSE OF IT!!!!!!
