I have an 2. But I am pretty sure I will be using my s14 one.
I have an s13 one 100k just shot 175 psi on every cylinder. No ecu or harness.
As for my s14 KA. If I were to sell it. Motor has less than 10k on rebuild I believe it was 190 psi on every cylinder maybe $400 harness (MINT UNCUT) $100 ecu $30.
Still undecided. I really want to use my s14 KA.
