Hi to every one.

I have a b16 eg and i am thinking of doing b18c4 coversion with itr rods and pistons with double valve springs with skunk2 stage 2 cams.

Dose anyone know what the compressoin ratio will be, and what the pros and cons of this type of swap and any tips would be most gratefull.

(Just to let you know this is the first time for me to do any type of engin swap)

Snoopy

compression would be 11-11.5:1.

pros - nice bump in power and torque if tuned properly
cons - blown motor if not tuned properly, headaches if you dont know what you're doing

Do you mean if the timing is not tuned properly or is there other causes to pay extra attension to.

And what type of power would i be expecting (i assume 200-210bhp)

Snoopy

fuel and ignition timing must be properly tuned to keep your af ratios in check.

Would a standard itr map be ok. then fine tune af ratio.

Snoopy

as long as you only use the it basemap to get to a tuner

I am picking up some itr pistons and rods tonight they are out of a 98 or 99 dc2 and i will be getting new rings and bearings. Will used pistons with new rings work fine?

Thanks for your help.

Snoopy

as long as there is no scoring on the skirts or cracked ringlands you can reuse them.

get honda bearings only

I want to get honda pistons rings as well, but i haven't priced them yet.

What size rings would i need?

And will i need itr injectors? or will the standard b18c4 be ok? I will be having a 9k rpm limiter
