I am planning on running b18b turbo(t3) at 8psi, is b16a3 tranny too short for this set up, this is a daily driven car..

 

what kind of racing are u going to be doing?

 

if u dont care about doing high RPM's on the highway. and as long as ur car only traps like 100mph in the 1/4 then u could probably get away w/ it w/ out haveing to shift into 5th. if u trap over 100 at least get a GSR tranny. but the car would be hella fun w/ the b16a tranny, insanly short gears and good acceleration but very low top speeds for each gear w/ only a 7k redline.

 

listen to him

but you could swap an LS 5th for highway driving. But you would still top out 4th at like 10xmph@8000 RPM. Not the best for Track

 

oh , no, not this again..
lets try to leave it at direp's post

 

what's the top speed on 5th gear on b16?

 

I just was at 8000rpm tonight in 5th in a '00 Civic Si and my speedo said 142.

Oh, and use the B16 tranny, don't list to anyone else. It's sweet. Ask Karl (Jinxproof) how it works for the 1/4 mile

EXACTLY specially with slicks.
the top speed of the tranny is like 140-145 mph i think(actual) of course your speed is off at that speed.
ive hit 145 indicated before(no turbo) but im sure it was more around 130-135 as i still had rpm left and the gauge is off at those speeds

 

alrite, thanks guys.. I dotn think I will hit over 130 in a EG...
I guys I will go with a b16 and see what happens.

 

I'm running a type r tranny and If I'm correct they are are the same except for 1st which means nothing. My car is turbo and I love it. Mine does 140+ in 4th at 9800rpm. You'll get thru the gears quicker and stay in your powerband.

 

yeah. the problem is I can only go to 7k rpm.. since i have a B18b..

 

It works fine for me. I have type r tranny, B18B with drag3. The only problem is the highway. I wonder how long it can handle 4500rpms for? But so far no problems. You shift alot, but if you like shifting(I do), you will like it. I have considered an LS tranny and putting in LSD though.

Here is a link to a good gear ratio calculator.....

what mph is the 5th gear @4krpm

 

i have the stock B16 tranny with a CTR ecu in my Si and 4th gear will top out at 125 at 8600 rpms

 

Just over 70 mph. 70 is 3851rpm with stock 93 si tires.

Try the link I posted above.

 

what size tires do you have? You can check your speedo accuracy by going to tire rack, getting the rolling diameter of the tire, putting it in the calculator above, and comparing.

 

in my Si(R) im at 3400 rpm at 60 mph
