Sell the car - but a turbo model.

Then you get the brakes, gearbox and everything else.

It'll cost more to upgrade your bits than it would to actually buy a car and just use what comes standard.

What are you trying to achieve with a 6-speed gearbox anyway?

It'll cost you 5-6x as much, and really offer nothing.

thanks man, down the line when im finished the engine ill probably go all out with the 6 speed gearbox,

but atm ,

im up to getting the mods (in progress) and fitting them, tuning it, work out all the kinks, lay down some 1/4 mile times, hopefully some track runs

and then worry about cruising down the highway in six ,haha, would be sweet though.

cheers.

Keep us updated with ya progress man.. and welcome to the forums

f**k why do threads like this end up with ppl giving him so much shit?! Its pretty obvious from his first post he was just after some advice/opinions on the matter.. Sure, heaps of ppl are helping, but he's also getting a bunch of f**kwitts that act like its money outta there pocket and some sort of insult that he wants to do something different.. If you have nothing helpful to say f**k off.

Different is one thing, a gross waste of money is another :)

But ye, not the first "i wanna put a 6-speed" thread, there have been many in the past, and thankfully people realise there is little point and stick with the normal 5 speed.

Also the same for getting a N/A upto a turbo-spec type thing. Easier and cheaper to start from a turbo base.

mate im in the process of an engine build,

and i beleive an rb25de head iis better, then the rb25det head when building this sort of thing ,

sure its harder, but its what i want to do, so enough critism mate.

i am asking for info.

Nismoid does have some solid points man, in just about every case its going to be cheaper and easier to start with the turbo model as its base has the better gearbox, diff and brakes as far as im aware. Having said that, i completely agree with your decision to do it your way. With these forums having wrecked turbo models all the time, you can pick up all your parts really cheaply anyway. Plus the plans for the car sound awesome.

well s15 6 speed is a pile of shit when lined up next to rb25 5 speed.... so dont bother looking at this as an option.

s13 never had 6 speed.... so yer i dunno what you meant by that.

With a lot of f**king around you can get a gtr box to work but im slightly confused as to why????

if you can give reasoning for ur want of changing to 6 speed then it may help.

unless u regularly drive down the highway at 160 kmph then what is it needed for?

and if your doing track work unless your thing is a missile you wont need 6th gear i would not imagine (depending on track)

if i was going to contemplate spending this much money doing a 6 speed conversion i would just bite the bullet, borrow some money and put a 6 speed sequential hollinger in my bus hahah

from what i recall, to make a gtr 6 speed work well you would also need the diffs, once again cost is going up for no real gain

as everyone has suggested already through experience and knowledge its much better to stick with the 5 speed

6 speed may not change final drive much anyway, it will primarily fill in gaps, which with the torque that an 30/25 will make is going to be of little benefit, you may even find that on a track with the weight and extra changes you will go slower. But you did say that you were just after advice about which box to use, maybe a Supra box?

thanky you, finally someone understands, its not about performance its about drivability sure the 5 speed is great, but i want a 6 speed, i dont need one i just would like to have one.

started with the n/a so even shitty turbo wrecked parts is a start lol, ive got the engine and drivetrain part going good so far, so the wrecked turbo parts ect turbo brakes ect will be all i need. for the time being until i get into serious stuff like racing, track work ect but right now its basically a sleeper project that isnt a typical sleeper, thanks.

im just contemplating my options ive always wanted a 6 speed not to make my car go faster (cause theres no difference except for the extra gear) just cause i want one, am i being so obscene to want to do it my way?

sorry about the s13 6 speed, some dude informed me it was good, ( to bad theres no such thing) thanks.

yes thanks, ive always liked the supra 6 speed, im not worried about the final drive ratios ( i would've just changed the diff ratios lol) thanks mate

from what i recall, to make a gtr 6 speed work well you would also need the diffs, once again cost is going up for no real gain

as everyone has suggested already through experience and knowledge its much better to stick with the 5 speed

im not after gain though, im after a nice drivable car capably of cruising down the highway (my ratios are f@#%ed im doing 3400 rpm at 100kmph in 5!)

while also capable of some sweet power,

thanks for your input, cheers.

Keep us updated with ya progress man.. and welcome to the forums

thanks man good to now there are some good guys that are actually interested in my plans and not just try talk me out of it cause they dont like the idea, my car , my plans , my way . cheers mate thanks heaps.

    • My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.
    • Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?
    • What about if you just give it direct 12v and earth?
    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
