Just asking a question after doing about 2days of research.

If I build a RB25DE engine,

Lets say I put ITB's from RB26Dett manifold
Put RB25DET Injectors

Would it be possible for me to increase the Compression ratio to 10.5:1?

Also, with that compression Ratio, Will it be possible to put some 256degree 8.5mm Tomei Cams?!

Its just an idea that I was looking at because I see a lot of ITB's builds but no information on them really.
If someone can link me to a place with info, that will be nice.

Also, If I was to tune this, ( Wont have an air flow sensor OR Manifold Air Pressure) What ECU would I be able to tune with?

Something that's TPS dependant? Ideas?

Thanks\
