Some background: Been slowly chipping away at modding my auto 4th gen since 2004. Got an invite to drag racing and everything progressively spiraled out of control from there. Got the auto 4th gen from running ~16.3 to 15.3 but this was not good enough... The need for speed had me looking for a Crx del sol chassy (non transtop manual) for an H22A transplant but after no luck, a 4th gen manual Prelude caught my eye... A phone call + one plain ticket + a heap of cash later I found myself the owner of manual 4th gen.
Having lead a humble life in stock trim for 250k kms, the time has come for a transformation... In the short term, I am aiming for 13 second passes down the ¼ mile and somewhat more long term I aim to get 200wkw NA out of the H (eventually, after much $$$ and hard hours...lol.).
