Newbie question bout ls

[Brandon619]

Hey im pretty new to the civic world i just bought a 92 coupe with a 94 b18b motor in it it has I/e/h when i bought it the guy said it wAs tuned but iam wondering why the rev limiter hit at 6k rpms??? After searching the fourms i found out that they say the ls motors make max hp and tq numbers at 6200 so my question is am i losing power by the rev being set @ 6 k any help is apprecaited

It's more likely that your tachometer is incorrect because if he had it tuned they wouldn't lower the rev limit and if it isn't tuned it wouldn't stop there either. What rpm are you at when you hit 70 on the freeway? The limiter on that engine should be 7200

Hell I don't think that any of our american D series are even limited to 6000

Umm bout 3500

If your around 3500 at 70mph and ur tires arent ridiculously sized it sounds like you have a GSR transmission, or more likely your tach is incorrect. Borrow one from a friend or find a cheapo external one and test that out first cuz the LS trans should be around 3000 or so.

On my d16y8 redline is at 7000 rpms and the stock rev limiter is set at around 7500 rpms yea I've hit it a couple of time

How can i tell what tranny i have i looked on the tranny and its just a bunch of numbers on the plate

 

[speedygonzales]

google the numbers that you find. it'll be either the part number or transmission code I can't remember which it is. or post the numbers that you find, in this thread and some one will be able to help you out with it

I tried googling it nothing came up the code is JH4DC2397WS001334 and im pretty sure its not a cable trany...and back to the orginal question my ecu is p75 i took it out and swapped in my cuz ecu pr4 i believe and the rev limiter still hit right at 6k is there any other way the old owner could of changed it???

JH4DC2397WS001334 is the vin number

DC2= B18C

3: 2dr 5spd

9 GSR- Leather seats

W Model year - 1998

So it seems like you have a GS-R transmission
