So Im upgrading my B18B1 (LS motor) to a JDM B18C (Type R) but I have a full race turbo kit on there now.

I know the exhaust manifold/turbo setup will fit the new motor, but Im mainly concerned with the clearance of the downpipe, ground and oil pan. Are these dimensions the same or close at least? Worst case, Id get a new downpipe made but Id like to know what to expect.

Im making new intercooler pipes anyways so ill be good for that. Just worrying about the downpipe, lol.

 

The deck height should be very similar to each other, if not the same. You'll have no problems with clearances, or fitment issues.

 

I hope your getting a new tune

 

should be, for the most part, a direct fit

don't even consider driving that car anywhere but straight to the tuner and out of boost
