i have a quesion to see if the trans will hold up to the power that i want the pro to make in the very soon future.

what is the major problem with the g series transmission.

can they hold up to some number like 500hp?

i have heard that people have had problems with the gearbox going out and the axles braking? is that true!

what about the wheel bearings? can they hold up too the power.

splinder gear have a problem?

lsd would be the next quesion. there are Phantom grip, msp lsd, then the QUAIFE.

i am not the transmission king so this is why i ask i am a body man but i can do some work. the plan was more then likey the quaife lsd a trans rebuild, custom axles, CLUTCH MASTERS Lightened Flywheel, CENTERFORCE Dual Friction Clutch Disc And Pressure Plate (will the clutch hold up ), if there is some thing that i am not thinking of then please let me know. if the parts that i have listed will not hold up to the 500hp please let me know my plans are to build the highest horse power bp turbo nitrous motor out there.

The tranny can hold as much HP as you can throw at it.
They start to break at ~350ftlbs of torque.
You've got a long way to go if you want to build the highest HP BP.
Dave Lauzier's MX3 was~570hp when I saw it up for sale.
Stay away from the CF dual friction clutch, they wear out rather quickly.

The mazda DOHC tranny will not hold so much power but a kia sephia tranny will hold the power because the axles are more heavy.Here in the island we use to have a 323 running 9.5sec 1/4 miles and the axles will not hold the power so the owner decide to get of the engine of and put a MR2 engine and tranny for the moment.

so the transmission will hold up to the power and the gears will not have a problem?

what about the gearbox? i have read is some places that the gearbox has a hard time living up to the power.

on to the clutch. if the cf wears out fast then what kind should i use?

then the axles i will have to go some place and get some custom axles made?

this will tell alot about how the transmission is going to be used.
i will drag it sometimes but not much, i am really planing on making a highway racer out of it ( you know like 40 to 140mph)
i would really like to see my pro out run any of the camaros, mustang, and this fast *** mark8 that my buddy has build.

so then the transmission will be build like this:
transmission: rebuild
clutch:need to know which one is the best to use
axles: custom from the nearest shop.
lsd: mazdaspeed or the quaife
flywheel: miata aftermarket or the clutch masters
gearbox i am still worried that the gearbox will go out and i do not want that to happen.

ok any other thing that i should have to buy aftermarket
i am working out time to get this done as soon as poss so i need research material.

i want the transmission to be almost " bullet proof "( very strong do goes crazy on that remark) before i go ahead and build the engine so any input is great

midnightblue97

How do stronger axles make the tranny stronger??

midnightblue97

Torque breaks transmissions not HP.
The Strongest G series boxes can hold roughly 350FTlbs of torque before they go south.
Tranny= gearbox

Clutch masters, ACT make good clutches. The Centre forces are good but because of the dual plates, they wear faster because the friction material is thinner to keep the stacking height the same.

I don't know for sure. The biggest problems I can remember reading about were trannys breaking not axles


As for an LSD I don't know how much the oner from the MSP can handle but the quaiffe is known for being quite strong.

midnightblue97

I don't know much on this subject. You can try shot peening or Cryo treatment, but I can't really answer any questions on those processes.
Expect either process to be expensive however.

Start by braking one then you'll see what's needed to improve on it. What going to be your set-up to make 500hp on the bp seems a little high for street use.

scottie855

i do not want to go into the engine at the time trying to keep everything under warps but 500 or more will not be hard. but i am trying to attack this project the smartest way. build the trans before i go ahead and build the miny monster

"Torque breaks transmissions not HP.
The Strongest G series boxes can hold roughly 350FTlbs of torque before they go south"
TRUE but just did not state the answer in torque but in hp. but for the 500 little ponys that will be hinden in the engine bay then the torque will be almost there too right. RIGHT

so there is no way to get the gearbox any stronger?

what about the wheel bearings?

nobody told me if there is anything else that i should look into about buying to hold to the power. i will state again i do not really know to much about the transmission so anything outside the normal please say something about it.

"Start by braking one then you'll see what's needed to improve on it"
i don't want to break anything for a long time i am not going to hold back on any penny, i am trying to build something that will last every expensive part will be had. if there is no way that the transmission will hold up to the power then i will have to find another car that will. so transmission guru's fix the problem.

I am anxious to see how this guy's gonna make 500hp too... even the Focus / Honda / etc. guys have problems making that kind of power and keeping it streetable (I know... I was trying to design a combination to get just 300FWHP and it was hard without running Cam2 only and revving ut to about 9k, even with the engine max-overbored or stroked)

I can honestly say if you make 500hp you will most likely have the fastest BP out there.

skr33t_rac3r

hes gonna cheat and add like a 350 shot of naws

macdaddyslomo

a 500hp protege for sure will have to be a drag car, as those are the only ones i have heard of with that kind of power...I will humor this for a moment and give you the info you are looking for...it will be difficult to make a g series "bulletproof" to 500hp(assuming you are getting close to 500lb-ft of torque too)..first things first...weakest part of the tranny is the diff...have to go with a quaife lsd to handle the power...then look at probably a clutch masters 6 puck,probably like a stage 5....then look at getting gears shot peened....you will need custom axles althought this wont help the tranny at all 500 hp will snap stock axles like twigs....also you may need custom lugs too as this much power will want to throw regular lugs, and if this happens they are almost like bullets,very dangerous....just out of curiousity though....how do you intend on acheiving 500hp??? high boost and N20 ??

skr33t_rac3r

im thinking more like high boost and alot of nitrous

scottie855

i really do not want to go into the engine now but higher compression, very high boost with a small shot more then likely wet shot. but i don't want to go in to the engine now but the plan is spring transmission with the engine coming in the summer. nearing spring so i need to know the best transmission setup there is.

what does he mean by custom lugs? the studs or the bolts themself.

i still need to know what about the wheel bearings?

the lsd i all ready realized that the quaife is needed.

the clutch, and the flywheel i have decided on.

i need to know about the gearbox and the other things that are not the major parts.

i have no idea what to do about the smaller parts.
