I have an extra 99 gsr block lying around.
I blew my SIR2, and I was wondering if I could do this combo.
What will I need from one engine to the other?
Is the head compatible without any extenal oil line?
What other miscellanous things will I need?
 
Yes it is possible, that is pretty much what an ITR motor is B16 head (slight port on the intake side) and GSR block.
 
If you want use an ITR head gasket, and pistons it is up to you, ITR pistons will give you a better compression ratio, than GSR pistons.
 
what would be the best set up for this_
My budget is kinda tight.

I was thinking,
B16a pistons
Gsr head gasket
Gsr crankshaft
ported-polihed head
b16a oil pump
Gsr fuel pump
gsr tranny

What ecu :blink: Ive got a p30 but can trade for something else.
Which OEM fuel rail, injectors?
WIll it be a drop-in swap?
 
Bump.

I would totally like to hear about this one as well! I'm pretty much in the same boat.
Mine is the same but I would have to use the JDM B16A SiRII Tranny, and mostly B16 parts. What would be the run-down on this block swap? How about difficulty?

And the last and stupidest question of the day........Is it worth it?
 
Use the JDM pistons, higher compression.
 
You will need to machine either the pistons or the rods to make them fit together. I am not sure which ones need the machining, as I have not done this.... Yet.
The p30 should be fine, but you are going to want to get a VAFC, or Hondata. Hondata would be better but a good deal of tuning can be done on a VAFC, and they are relativly cheap.
