Hey there, this is my first post ever in the community. So my intentions for my 2000 Acura Integra RS is to have completely stock GSR internals. I've come across a JDM B18C being sold for a really good price. It's the entire swap being sold to me. Long block, transmission, ECU, etc. I'm planning to do a full rebuild on it with guidance from the book "How to Rebuild Honda B-Series Engines" by Jason Siu. The rebuild parts that I want to use is a GSR rebuild kit from Ebay. It's easier for me this way and it's also affordable. I've done plenty of research on the differences between B18C1 (USDM) VS. B18C (JDM), and I haven't really found any specific differences other than compression ratio and mapping. So my question is, if I rebuild my B18C with a GSR rebuild kit, will I be able to use the stock GSR ECU and have identical GSR functionality (what I'm looking forward to)?
