i think my friend is on hash.

I would love an auto, boosted launches RULE! Ive even contimplated ATI's th350 kit.... mmm.... stall converters... and consistency too!

boosted launches rule, your autotragic crapping out on 10 PSI and a full exhaust system is not.

I am also contemplating the manual swap, but the automatic is plenty fast, and just so comfortable. The slipping is driving me mad, however.

 

[suprashred87]

hm....alrighty, thanks!

I went auto to 5 speed, and I'm glad I did. It all depends on what you want out of your driving experience. I don't care much about what an auto can offer at the strip, and think a manual is just more fun. Where's the 5 speed love? :dunno:

Edit: I did mine for just over $1000, including a brand new engine harness (i.e. $600 for the tranny swap)... Shop around for some deals - they're out there.

 

[supramike7m]

oh and to answer your question, your buddy is right, the driveshafts are different lenghts.

 

[TheAmazingDave]

An MR2 with an auto is sacrilege, an auto in a Supra is almost fitting.

Too bad it sucks.

i love the 5spd. tons of fun. i have an auto 1jz and 5spd 7m. i dont really like the auto much on a 1jz though, they dont have enough torque to spin the tires no matter how hard i try. the 7m on the other hand, before i swapped could spin them quite easily off the line.

 

[suprashred87]

so then guys, i think my mind is made up. painting it black<it was white> changing the tranny to 5 spd, dropping the twin 2j doing a head and cam kit, intake, exhaust, and having the engine rebuilt with roickin solid parts. that should net a decent amount of hp. im not looking for too much. thanks!

 

[supramike7m]

how much power you wanting? im pretty sure a stock 2jz will handle anything you can throw at it, it already has roickin solid parts from the factory. there is no reason to upgrade the internals unless you want like 900hp, or unless you like wasting money, which your swap is gonna cost you "several" thousand already.

 

[starscream5000]

If you put a 500 HP built auto supra up against the same setup, same tune, but with a manual, the manual would loose every time, and would most likely still loose if it had 50-75 more HP than the auto.

Autos are more expensive to build to make them handle the HP, but they are better in quite a few areas:

1.) Boost off the line. A manual can't do it unless you two-step.

2.) Consistant results every time at the track. The same can't be said for the manual.

3.) You will gain your respect once you hand everyone their ass who has a 5 speed and thinks that they are superior.

4.) Tons of different ways to modify the tranny for your specific setup (kick down, stall converters).

 

[blackturbona]

im with the manual guys. i just feel so much better driving a manual and having full control of my gears and everything. also i never take it to the strip, although i should, so consistancy isnt important. also i have the worst luck in the world trying to street race, as in, i NEVER find ppl to race but a auto to manual swap does seems kinda silly based on price and effort

 

[suprashred87]

oh, so no need to reinforce the internals if im only shootting for 400 MAYBE 450 hp? awesome. and i really just want a manual tranny for a fun driving experience, not a boring one. thats all. lets not argue over transmissions. that would be dumb.
but lets say i end up with 450. with a good tuning, how much do you think will end up at the tires?

What can I do do improve the shifts? I am only looking to put ~300 hp to the ground. Already with what I have, the 1st-2nd shift is horrendously long in either ECT mode, and it seems to take too long to lock up under boost.

I was going to have a shop flush and fill with Redline synthetic ATF and add an extra cooler. Do you think that will help, or is the problem more internal?

There's only 68k miles on the transmission.

 

[Fuzz420]

do u mind introducing me to your friend

 

[suprashred87]

hahaha. sure! he'll give ya a sweet deal too rofl.

 

[Doward]

Yeah....

Automagic ftl. I bought a Supra to DRIVE, not to suggest where it point itself :3d_frown:

Manual advantages (just to be on the opposite end of SS ):

1) Direct mechanical connection between engine/transmission = Less parasitic drivetrain loss = more power to the wheels.
2) I can lose 2nd gear, and continue about my merry way
3) Battery died due to radio blasting while working on your buddy's car? Push start it!
4) $300 clutch job vs $1500 transmission replacement.
5) No cooling lines adding extra heat to your coolant system, or being a PITA when working with the radiator.
6) NO LEAKY TRANSMISSION PAN.
7) Much more respect when you can run consistently, with a stick shift.
8) No need for a 'shift kit' - if I want performance shifting, it's up to me. If I'm cruising and want the shifts to be buttery smooth, it's no problem. There is no 'compromise' with a manual transmission - you do as you want.
9) R154 handles more power than the A340e, stock vs stock.

And most importantly:
10) Though you may be able to put your hand on your girl's leg as you drive, it won't help you. She's still going to sleep with me, because even chicks know that MANUALS ARE COOLER THAN AUTOMAGICS.



10 reasons a stick is better than an auto. And two-step FTMFW.

 

[suprashred87]

ROFL! GO DOWARD! LOL. THAT MADE ME SMILE!! AHAHAH

you really need to read up on a 2jz, seems you have no idea of the capabilities. 450 hp on a 2jz is nothing. id say about 390 whp if you have 450bhp. stock twins can handle that power. factory internals are capable of 3x the factory rating. id say with intake, exhaust, bcc, boost controller,intercooler, your approching your goal.

I can't offer good advice as I also have a manual tranny, but if I had to do it over again, I would have bought an auto because it would have fit my purposes just fine.

An auto will be more expensive to build for high HP, but if racing is your thing, then auto's the way to go. As stated before, a manual car with the same setup can have more power to the wheels than the auto and still get beaten. It's impossible for the manual to shift as fast as the auto, plus, you don't loose boost between shifts in an auto :sarcasm:

If you want to look cool, ocasionally do a little street racing, go manual.

If you want the ease of driving without worrying about changing gears, go manual.

If you want the fastest times you could get on a strip, a built auto is probably going to be your ticket.

You can chose what gear you want to be in in an auto to who ever mentioned it, it's called Suprastick v4 IIRC, ask Ian how well it works .

 

[Dan88t]

I've been debating whether to start a thread about this or not but here seems like a good enough place to ask my question. Everyone seems to swap from manual to auto, I have an '87 and an '88, one is auto and one is manual. I'm making one frankenstein out of the parts from both and that means I'm swapping my auto tranny into the manual shell. There dont seem to be any threads on that swap.

So my question is, what do I need from the auto car? Besides the obvious, transmission/shifter... The TSRM tells me there's a transmission computer hiding in the cabin somewhere but my quick glance didnt turn anyting up the other day. I think I remember someone saying the gauge cluster is different, is that just because of the normal/pwr lights?

What's the going rate for a used r154 these days since I have one laying on the garage floor that might need a new clutch but is otherwise fine?

 

[suprashred87]

sorry..but..what is bcc? i couldnt find the terms outside of blind carbon copy, lol, and stuff to do with economics haha.
