I'm getting mixed reports - so i wanted to start a thread with this topic and get things on the table.

I have a 99 LS engine ... recently broke the differential on an LS tranny and I'm thinking of putting a Type R tranny on there.

Now I know the gear ratios are different than the LS tranny, but with a little help i would try to gauge by how much this is different. Anyone with experience on either one please let me know.

Is it worth considering opening up a brand new Type R tranny and include the final gear from the LS tranny - to get the best of both worlds - quick start and milleeage on the highway with lower engine revs, or not.

Is the type R gear ratio different enough to want to consider just getting a solid diff in the LS and run it like that?

thank you for your input on this.

 

The difference between a Type R tranny and a LS is like night and day. Please dont get a Type R tranny and put an LS final into it. Just take the ITR tranny as it is.

Here's two links to look at...

Can I please have the reasons why you're asking not to swap the final drive in a Type R tranny?

I would like to understand what your rational is and what makes you say that.
Thanks much

I think it may be too big of a jump from 4th to 5th. You may have to push 4th every time to be able to maintain speed in 5th.

Use the calculator I linked you to, to find out

:taps gaydar: "Is this thing on?"
Use the calculators to see what your frankenstien tranny will end up doing. Look at where you end up in the next gear after shifting at redline.

i don't know what kind of girls you're hangin out with

if that's a chick then damn...i bet she's british or something, if it's a chick

 

well - i'm glad were sticking to the subject here ...

... still no valid reasoning for not changing the final drive in the Type R with an LS one.

I doubt you would have to redline it in 4th to get the 5th to work
Any wisdom on this?

She looks female to me. The cheekbones, plucked eyebrows, and eyelashes...it's a girl.

Tried to use the calculator, but I think it's fucked up.

For the LS final
6800...4th gear....101

101......5th gear.... between 5000 - 5500

For the Type R final
6800....4th gear...97

97.....5th gear.....between 5000 - 5500

Do it, and tell us how it goes

 

If you want the ITR transmission for performance, you are essentially hindering that by swapping an LS final drive and wasting money on an ITR transmission. Why not just get a GSR transmission and swap an ITR LSD? The 5th gear RPM would be lower than the ITR with LS FD without sacrificing 1st gear acceleration.

Keep this on topic.

 

Well - I got the Type R transmission in place.

A little background information and specs:

LS Block/Type R tranny/T3/T4 turbo/ODB1 (downgrade)/eManage/auto-manual conversion

The readouts are as follows - the speed is OFF by 5 miles on the high side - i know this because i compared speeds with other vehicles on the road going the same speed as me.

3100 rpm - 60 mph - 5 = 55 mph
3400 rpm - 65 mph - 5 = 60 mph
3700 rpm - 70 mph - 5 = 65 mph
3900 rpm - 75 mph - 5 = 70 mph
4100 rpm - 80 mph - 5 = 75 mph

**********************************

these ARE the ACTUAL numbers - drove the car in this morning. No guessing.

**********************************

I'll keep posting as i get this tuned more and get the new tranny settled over several hundred miles.

I may post mpg also if anyone is interested.

That is kinda high, no?

Did you get the car dynoed?

 

You're not kiddin it's high.

I remember when i had this on automatic - i was at 80mph at 3000 - 3050 RPM.

I mean ... now it's off by ... 1500 almost.


No - i did not get the car dynoed yet.

 

Your tires could have something to do with the speed being off.

Normally, it will not always be off by the same amount.

Ex: 40 is really 45
50 is really 57

stock type R specs
80 mph is about 4200
70 mph is about 3800
60 mph is about 3100

 

The wheels/tires are indeed different - but check this out:

http://www.miata.net/garage/tirecalcold.html

and put in these numbers:

195-55-15 vs 205-45-16

the speedo should be off by .5mph - not 5MPH

 

I looked it up on Team-integra and found the same...

Speedometer(mph) / Actual(mph)
30 / 29.7
40 / 39.6
50 / 49.6
60 / 59.5
70 / 69.4
80 / 79.3
90 / 89.3
100 / 99.2

 

I know - i posted about this a while back to try to figure out what's causing the speed reading difference and i didn't get too many responses.

That's not to say - probably at all.

Plus - the tranny speed sensor is identical for both auto/manual.

Did you ever change the gauges?

Maybe try and change the speed sensor.

 

No gauge replacement done.

I inquired about the speed sensor - as these are not necessarily cheap ... they are identical. No need to change those ...

Just woundering if they can ever go bad like what has happend to you. Maybe look in some junk yards for one.

Other than that, I've got no clue what could be causing it
