5 speed transmission limit ?
Hey guyz, new to this nice forum!!;);):wavey:
I have some money saved and from what i will get from my parents i want to buy a supra! but because the twinturbo supra is so expensive :eek: i will buy the na-t 5 speed and make a conversion. A) I wanted to ask how many HP can i reliable get from the 5 speed tranny ??:dunno: and if i can only get ~320 hp, can i make something to it(the tranny) to withstand around 450-500 hp ? :D B) I saw the xs power kit on ebay > LINK < Is the T61 turbo reliable or is it better to buy the kit + a better turbo separately ? I plan on buying the kit + bigger injectors, another headgasket for compression, upgrade the fuel pump and mapecu. But I can't do all this if the tranny will broke, so how many hp's is the limit ?:bigthumb: |

The 5spd can hold about 400rwhp. A T61 is reliable. You should always get a complete kit (eg. fuel kit or turbo kit). Do not try to piecemeal it together with turbo then header then hoses/lines/pipes/couplings, or injectors separate from fuel pump separate from fuel rail, and then try to piecemeal it all together and make it work. It probably won't work properly, and you'll end up with weeks or months of headaches. |

I think you are kind of right, but the next affordable supra is the auto tt supra...i've driven auto cars before but nevers sport cars...isn't the supra kinda meh with the auto tranny ?And plus how many hp could it withstand? The manual tt si expensive :( and after that i have to make it like apu for ~ 500 hp, right :(? that means at least 3000$ :eek:? with the fcd,ecc,downpipe,exhaust,cams etc ? EDIT : Or will I be better buying the auto supra + t61 kit ? Another set of questions and I won't be bothering you anymore. If I build the na supra, let's say to around 500hp / ~ 430rwhp...because I still think is less expensive then the twin turbo(I know it's not the better choice) and is better for me because I can add the turbo after like 1 month of buying the Supra(so I don't need all the cash in an instance), how much time will the tranny resist if I don't drive really hard ? And I saw some rebuild kits on ebay like THIS, are these good ? Because if it can hold this amount of power I don't mind paying for rebuild once every ~15k because I won't be driving too often. I know the brakes are better on the twinturbo, but are these necessary or just recommended ? What about the diff and ignition system ? Thank you again for taking your time !!!!!!!:wavey::wavey: L.E: What are the exact differences between a TT and a NA beside : brakes, turbo, tranny...do na's have ABS or Airbags ? |

Take a look at this technical article: www.mkiv.co.nz (check under technical section. A wealth of information on the Supra helped me a great deal. I'm also in the market for one - I desperately want/need it :crazy2: I found great deals in it's homeland of Japan so, I'll be getting a JDM spec - oh yeah! The w58 N/A tranny is capable of 260rwkw (I think that's 360HP) whilst the TT's auto A340E is capable of more at 350rwkw (+-470HP) and the king V160 6 speed TT tranny is capable of a whopping 500rwkw + (750HP)!!! Definitely the one to go for if you're running that power. N/A is great and very affordable. However, the Twin Turbo is the undisputed king and ultimate Supra MKIV - if you could possibly afford one, please buy it. If you really cannot, set up a careful budget for your N/A Turbo conversion - if done well, the 2JZ-GE can produce massive power as well. It's just much more costly of course. As for differences between the two, the article will have you covered there. Suspension wise, the TT came with Bilstein shocks, better ABS system, traction control as standard, spoiler control. Since you will be buying an export spec in the UK, the brakes are bigger than the N/A's. If you're buying from Japan, 93 - 95 Supras had the same size brakes for both TT and N/A. If you're pushing much more power than standard, upgrading them is a good idea with bigger rotors or at least slotted ones with better pads to match. If not, the Supra's original brakes (TT, especially) are very, very good in road or track scenarios. Best of luck bro! Keep us posted... |

2) MOST importantly, a strongly performing car is about SO much more than horsepower alone. What's the good of horsepower if you just sit there and spin with skinny 16" tires, or can't corner when you get going, or can't stop at the end? The Mkiv TT gives you all of that in one package, and the n/a does not. Quote:

The 5spd will probably hold 500hp for a good long while. The MKIII Supra with the 5spd has proven very reliable at that level. Quote:

The oem n/a ignition system ...for lack of a better term... sucks donkey balls. You'll need to upgrade it to make a reliable 500hp+ with an n/a-T. |

Secondly, I want to clarify some things about my future use of the Supra. I'm a student in London, and this thing means 2 important things: 1) I will only drive the Supra on weekends(+ I don't intend to drag race it for the moment or road race it too much) or MAYBE 1 time during the week if really needed as going through London is way better/convenient with underground/overground/buses 2) For the reason above, I don't have that kind of money to pay for gas every day and that's why TT manuals + upgrading are kind of over my buget for now(until I finish uni and get a job) because as I said before, I only have like 3k $ asside + around 3k $ from my parents; so the only affordable supra is the n/a or maybe if I find a cheap high mileage auto tt(but that means keeping it stock). Saving like 200$ per month for tt means I have to wait years, so i'm better moneywise + learning wise with n/a made turbo until I finish uni, get a job and afford a tt. I don't even think of buying the n/a auto, all the time I was referring to the 5spd n/a. You said it will hold 500 hp, well I don't intend on going higher than that because for my first Supra, my first 200hp + car and my first right hand drive car I think it's enough :bouncy: And why will I struggle so hard to achieve 500hp? You make it sound almost impossible :eek3:. From what I've read in the last week over and over again, the n/a with a turbo kit(intercooler, wastegate, bov etc) will make over 300 HP and will need the 1.3mm gasket to lower compression, map ecu, upgraded fuel system(fuel pump + 550 injectors) and ebc(to raise a little the boost) to make 500 hp. What I am missing ? :confused: Again, I REALLY KNOW why the TT is way better than the n/a(even with the turbo) but in my situation, as I can't afford the TT soon but can afford upgrading the brakes on the n/a after ~ 2 months, and then something else, piece by piece, I believe this is the best solution. Feel free to come up with other solutions/ideas! |

No V160 has ever failed at anywhere near only 750rwhp, except the 2nd gear synchro from abusive power shifting. |

Here's an example of a complete na-T kit: http://www.boostlogic.com/catalog/p1...duct_info.html ...and for $5250 you do get your 500hp, but on a car with substandard brakes and suspension. Based on your situation, I still say wait and get a TT. Doing all of these mods to turn an n/a into an na-T is something a student probably doesn't have time for. For what it's worth, I say take more courses and get your degree done sooner, or get two part time jobs and save up for a TT quicker. *shrug* Either way you go, I do wish you the best. |
I'm a first year student in a 3 years degree, so I don't understand how I can get my degree sooner. I will get a part-time job as soon as I get my right to work (~3 months), 2 pt jobs means full time and as I'm a student it's impossible. Saving like 3-400 pounds every month means I have to wait 1 year+ just to afford the TT 6 spd Supra...and a few more months just to afford all the mods to make it APU. So the n/a seems for the moment the best solution but who knows, maybe I'll win the lottery :bow: :rofl2:.
"note that a thicker head gasket in a 2jz-ge does not produce a combustion chamber with the equivalent shape and horsepower potential to a 2jz-gte" I know this, but I meant raising the boost from 9-10 psi (don't know the stock n/a boost level) to 15-16 psi, not higher. "You also still may run into detonation issues at lower boost levels" I also had in mind better spark plugs + better coils. That should do it, right? And for all the work I'll ask a friend to help me + I'm somehow a medium mechanic, as I've worked before at my motorcycles (when I used to ride them) + I've helped a friend build a 240sx, from whom I've learned some good things. For the harder things like the gasket kit and the drilling the oil tank, I'll try to find a good mechanic (who worked with supra's before). Thanx again!:bow: |

Another thing is, auto TT is considerably cheaper than 6MT. I'd advise you to go with that instead of the N/A if you truly want turbo power. Of course, it won't feel as dynamic as the 6MT :D If you do go with N/A, try to find an SZ-R (JDM spec and grade) post '95 - they have the same tranny and suspension (Bilstein shocks!!!) as the TT so, turbo'ing that baby will be even more sensible. Did you see any in the UK so far for good prices? Have you checked out the link I gave you?? Lots of great info there that will answer many of your questions on N/A - TT differences and conversions... Hope you get it soon :bouncy: |

The SZ-R is the perfect candidate for the n/a's, but it's rare... In UK, TT's go from 5500 pounds for auto's and from 9000 pounds for 6spd. And as this is the starting price, these come with high mileage or seem used hard so for a fairly good one add at least 1k more. The n/a's start from ~ 1750 up to 3000 pounds for a very good one. The thing is I could have money for the auto TT(even though I want the manual :(), but I have to keep in mind also registration costs, I want to fit an alarm with gps, service check before buying, changing oil, brake pads and etc beside the power increase which is the whole point :(... Pwpanas, what about the SZ-R, you haven't said anything about them. If I could find a SZ-R, I could also put tt calipers + brake disks and I could also rebuild the engine after ~1 year with TT pistons :D. I prefer this instead of waiting until like mid 2013 to buy the TT...:rolleyes2 |
