supraspeed Posted February 4, 2009 Share Posted February 4, 2009 ok sorted out a deal with the parts place about my 6 speed and are giving me discount on other parts i need....sooooooo... ok mines a 5speed n/a-single currently got the 6 speed box and as far as i know these are the only other parts i need so could anyone add anything else as i want to try and get it all bought in one go 6spd box tt propshaft tt flywheel tt clutch slave cylinder tt clutch anything else as i dont want to be missing anything once i take it all to whifbitz by the way i did use search but all auto-6spd conversions Link to comment Share on other sites More sharing options...
Homer Posted February 4, 2009 Share Posted February 4, 2009 Some details from a thread yesterday (it's about a 5spd conversion, but the points are still valid): http://www.mkivsupra.net/vbb/showthread.php?t=175841 And TLicense's 6spd conversion parts list: http://www.mkivsupra.net/vbb/showthread.php?t=91861 You are missing the 6spd diff and driveshafts from your list. Those are the only "big" items missing, lots of smaller ones though Link to comment Share on other sites More sharing options...

tooquicktostop Posted February 4, 2009 Share Posted February 4, 2009 Is Paul going to get the single working properly as well, as it would be a shame to have the drivetrain and not have the power Link to comment Share on other sites More sharing options...
supraspeed Posted February 4, 2009 Author Share Posted February 4, 2009 Is Paul going to get the single working properly as well, as it would be a shame to have the drivetrain and not have the power i'm hoping so yeah. everything i can in one go to get it working up to a decent standard....ish lol basically i just want it not to blow up, break down, or cause me any major problems. if i need to have anything major doing eg: like turbo replacement i'l just run it on no boost until i have the cash to sort it Link to comment Share on other sites More sharing options...

Drive shaft? thats a new one to add. i hardly understand a word of the 6spd conversion parts list lol. I might be way off here, but the it was my understanding that the 6spd prop is a different length to all others and therefore won't match up to the diffs in the small casings (NA and autoTT). If it's from an auto it'll be the smaller casing. Where was the B, at the start of the axle code or the end? Its the same reason the driveshafts need changing with a 6spd diff, they are a different lenght as the diff is larger. Link to comment Share on other sites More sharing options...

As mentioned in the other thread, you can either swap the diff and driveshafts or get the prop cut, welded and balanced and use the auto LSD, but it will make a difference to gear ratios. It's really advisable (ideal) to get the diff and driveshafts changed to 6spd items too, they are far stronger than the auto items, but the prop mod is always an option if you can't find a diff Link to comment Share on other sites More sharing options...
supraspeed Posted February 4, 2009 Author Share Posted February 4, 2009 sounds a bit involved cutting and welding. the place i'm getting my box from has got a whole supra man tt undamaged for breaking so i'l try and get the bits from them. they owe my a discount now cos of the agro with the box so i'l think i'l take advantage of it. ok... gearbox clutch slave cylinder flywheel propshaft driveshafts lsd .... probably more lol Link to comment Share on other sites More sharing options...

Did you see the thread link in my first post here? it didn't load at first but now i see. cheers. shit thats a lot of parts! hope the rest doesn't cost that much. this is going to be a laugh trying to negotiate these parts down the phone to the breaker lol. i dont know why whifbitz failed to mention this when i asked them what i needed.

Homer Posted February 4, 2009 Share Posted February 4, 2009 Apart from then relatively high cost of the diff and shafts the rest is more or less useless stuff a breaker will never sell. I got my 5spd including the entire drivetrain and all other parts including an NA engine for £350. Bargain with them hard, they should chuck in most of the stuff for next to nothing as they'll never sell them otherwise. Link to comment Share on other sites More sharing options...
supraspeed Posted February 4, 2009 Author Share Posted February 4, 2009 ok cheers. just wanna be prepared for it going in. probably easier to just say "everything from the engine backwards" lol Link to comment Share on other sites More sharing options...
Homer Posted February 4, 2009 Share Posted February 4, 2009 Are you stripping the car youself or letting a yard do it? There are a heck of a lot of bolts, etc that will be needed so it'd be best if you can get there are get the main parts yourself. Last thing you need is to miss a washer, etc. Any missing component will cause problems, delays and more expense to buy from Toyota. Link to comment Share on other sites More sharing options...

Terminator Posted February 4, 2009 Share Posted February 4, 2009 You do not have to change the diff or shafts when converting an auto TT to six speed, unless you are concerned about economy. You can keep the rear part of the prop as well. My conversion has standard auto parts from the back forward to the centre of the prop. The big advantage of my setup is the improved acceleration due to the box/diff ratios. You have to trade off some top speed and fuel economy. You don't need the front end of a manual prop either.Iif you can find a prop builder they willl cut weld and balnce your auto front end. We have a good prop builder locally, he made up a hybrid prop for our Skyline powered 200SX. They did an excellent job and balanced whole prop.

Homer Posted February 4, 2009 Share Posted February 4, 2009 Okidoki, I'm a bit busy at work right now, but will try and give a breakdown of all thats needed later/tomorrow. It's a pretty large list, but most of it is minor or worthless stuff that a scrap yard will miss Link to comment Share on other sites More sharing options...
Homer Posted February 4, 2009 Share Posted February 4, 2009 Good stuff Termi, so provided you take the hit on gear ratio changes no diff change needed The auto LSD is a lower ratio than 6spd isn't it? Hence longer in-gear ratio? Link to comment Share on other sites More sharing options...

Terminator Posted February 5, 2009 Share Posted February 5, 2009 (edited) Exactly Homer. I am still using the Auto LSD I fitted 6-7 years ago. I have put over 600bhp through it with some pretty violent torque gear changes too. I was originally going to try the Auto diff as an experiment, then put in the manual. I like the combined ratios so much am sticking with my auto based set up. The lost top end speed is not really an issue as most cars will not get driven that fast anyway. It is hard for me to recall as I have got used to my new set up. But at a rough guess, you are looking at around 200 - 300 rpm higher ompared to a manual diff at the same speed as a manual. On the plus side you have the extra torque generated by those extra rpm hence the more rapid acceleration.

However I am not 100%, but you may need to up rate your diff. I am not sure if the five speed diff is as strong as the TT's Link to comment Share on other sites More sharing options...
Terminator Posted February 5, 2009 Share Posted February 5, 2009 Just another important factor, when you use a manual gear box and auto diff you do need a speed signal corrector as the speed signal will be out. So you need to do the same if you stick with the five speed diff. Link to comment Share on other sites More sharing options...
