what trans??

[92sihatch]

I'm running a B16 swap in my hatch. I've got the S1 trans w hydraulic clutch. I drive interstate 80 miles a day. I need something that doesnt spin 5000 rpm at 75mph. What do I need to look for and how much difference is there in rpm?? Thanks

LS trans is the most economical in terms of gas mileage and price and will spin at a much lower RPM,I think around 3500.

get the gsr tranny - it is just about the perfect balance IMO

just put a ls 5th gear in it

Keep the B16 tranny. Put in a GS-R fourth and an LS fifth. Done.

Is it worth it, as far as fuel milage and the wear and tear of 4500-5000 rpm every day??

Probably...

 

[92sihatch]

Anyone have gear ratio's for all the(LS,GSR,S1)?

 

[BrutalB83]

Look in the FAQ/Reference section, there's a thread about it...

Got it, Thanks! Ok, if I am to buy an LS trans (junk yard hunting), what year car do I look for and what engine? How do I indentify it? I have a hydro trans.

Since you have hydro you want a 94+ trans, you'll notice a slave cylinder on hydro trannies. IIRC the trans's should have their code stamped on em.

94+ is hydraulic, that's what you need...
