what model of ecu is a P07? i got one with my d15b swap and instead of using that one i used my stock P28 from my d16z6. should i switch them or keep using the P28. i am not getting a codes and seems to be running fine. so should i not mess with a good thing, or switch. 2nd question is S20 tranny came with it. Does it have LSD?

thanks in advance

 

P07 is from a 92-95 Civic VX. Uhh an S80 tranny is from an Integra (DOHC) so its not gonna work with your SOHC...

 

he said s20. pm mistabone he knows his d series trannies.

 

Goddamn my glasses

 

s20 tranny's are from all 92-95 civics/del sols. Theres another code on it that determines what model it is.

 

Oh yeah...they will all work (d series S20's) but the one u want the most is the Si/Ex one. A lot better gearing

 

it is 97 SI tranny. at least that's what i was told. my question was this tranny have LSD or not. and will the P07 ecu be better than my P28?

 

USDM/CDM S20 trannys did not come with LSD.
96+ trannies are S40 not S20.
Unless the car is from Canada there is no such thing as a 97 SI, if it is from Canada then it's the same as the EX here in the US.
the P07 uses a wideband O2 sensor, EGR valve and lean burn cruising to get better mileage.
Unless you have the VTEC-E version of the D15B you do not want the P07, stick to your P28.

 

how would i find out if it is vtec e?

BTW thanks for all the other tips that what i wanted to hear. and yes the car is from canada and i am sure it is a S20 tranny for sure.

 

p08 is the d15b ecu and it will have LSD stamped on the tranny if it has lsd..

check the case of the tranny it will have larger black letters LSD on it if it has LSD.

If the head code is P07 you have the VTEC-E engine
if the head code is P08 you have the VTEC version that is closest to the D16Z6.
about the D15B - - http://asia.vtec.net/article/d15b/

 

look on the block and you'll see what engine code is stamped on the block, D15Z1 is the engine code for all 92-95 civic VX's that came with the vtec-e

the tranny codes are A000 and B000 i'm pretty sure that you want the B000 thats from the ex/si dont quote me on this tho

 

the s20 is the jdm version of the p20... the dx has the A000 stamping and the ex/si have the B000 stamping on either s20/p20...essentially, s20 and p20 are the same transmission but the p20 is usdm

 

thanks everyone
