TH350 swap or not.

[jessetooslow]

ok, well I can't make up my mind, I really like the automatic tranny, always have, I've owned 1 5-speed car out of 6. I know my tranny won;t last forever, so my question is, Do I do a stock rebuild, my car is turbo of course, buy a built tranny from IPT or do the th350 swap, my question about that swap is, how involved is that, I know a plate goes for like $5-600, is a real hard job, or pretty much straight foward, who has done it, what do you suggest I do.

Do you want over drive and how fast do you intend to go down the quarter mile? IPT tells you the trans is good for 10 flat and above, and to go domestic if you are serious and want to go faster.

You might search nosechunks. He was looking into a GM overdrive trans, but I don't know how that went.

 

[jessetooslow]

I don't really need overdrive, but its nice to have., I'm just loking to upgrade the tranny, how much would a stock rebuild cost?

Stock hydramatic, or Toyota?

 

[jessetooslow]

Toyota

 

[Nick M]

I am not sure if Toyota still sells an overhaul set. I was only prepared to answer the GM question.

Check Champion Toyota. Or IPT Trans.

 

[jessetooslow]

yeah, I was gonna buy a overhaul kit from IPT and have somoe to do it, not sure how much t would cost though.

I would think that a local trans shop, or chain would have a builder. The store may or may not let you bring your own parts.

That is when you ask the builder if he does side jobs. A builder, not installer.

Realistic HP goal?

yeah, my friend knows a guy who works at a tranny shop, he said he would install the parts for $1000

Realistic HP goal?

nothing crazy, but if I could guess, I would like to hit 400rwhp.

 

[IJ.]

Modded a340e then

Hammered mine at 550rwhp and it hasn't missed a beat.

OD and TC Lockup can't be beaten.

where did you get yours? what price?

 

[IJ.]

A place here in Australia called MV Automoatics, I paid $2800 AUD for mine to be built.

I believe IPT there do a good trans so are worth a call to get a quote.

i am in the process of the swap now. here is my thread (little slow going)

http://www.supramania.com/forums/showthread.php?t=79473

i had a full built stock auto on mine for several years and didn't have any issues. decided to change because the gm is geared well for drag racing, super strong and parts are cheap compared to a toyota trans. also for drag racing you can run a transbrake on the gm.

expect around 1000 rpm more than stock at cruise speeds and a reduction in mpg if you do a lot of highway driving. city driving it wont be quite as noticeable.

 

[jessetooslow]

here is another question, how reliable is a NA auto transmission, can I put one in my turbo supra for now, the car is stock, how long will it last?

 

[IJ.]

NA Trans has less clutch discs but is still quite stout so as long as you keep it cool it should be ok to use.

 

[jessetooslow]

what is the difference between the 2? so it should be ok to use, I was gonna get a na tranny off ebay for cheap with low miles for now.

Will the NA trannt bolt right in, or do I have to do any mods?
