can a B18C1 (GS-R) motor fit headers and an exhaust for an LS motor?

[RyanDC2]

I bought parts for an LS motor. Come to find out the motor in this car is a B18B motor... but I have a GSR now with a B18C GS-R motor. Will the Megan Headers and the GReddy Evo 2 full cat (LS motor) fit the GS-R B18C block? Please Help!!!!

You made another thread? After the other one had like 8 replies? wtf?

Yes, the bolt are the same pattern/length on both motors, the flange will line up exactly. The only distance is the LENGTH of the header. You may have to get an LS catalytic converter to have everything bolt in like it should.

It should be fine if you bought the header and catback for a 00-01 GSR. If it's for a 94-99, then the lengths will be off.

header will be absolutely fine regaurdless. exhaust may have to relieve a few inches off..

The header will bolt to the head regardless. A 94-99 header will not work with an LS catalytic converter. The 94-99 model GSR exhaust system has a shorter header, longer cat and longer B-pipe. The LS, 00-01 GSR and ITR all have the same length piping and will work with each other.

94-99 GSR exhaust parts will need to be modified if you are using anything from a LS, 00-01 GSR or ITR.

The LS parts I ordered are 94-01 motor. the GS-R is an 01 so yor saying I won't have a problem at all!
