You don't need to build an sr20 to have a reliable 400hp engine. If you DO then your tuner is garbage and relies on those aftermarket internals to withstand his too-aggressive tune.

At 400rwhp I would say the bottom end of any stock sr20det is on borrowed time no matter how good the tune. That is close to what,
460bhp? Almost 500 from a stock 20 year old 2liter engine is asking for oops no matter what manufacturer.
The
mistake here is trying to modify the sr20 without owning the
machine shop equipment to do everything yourself and being experienced enough to do it well.
sr20/
2jz is an amazing engine. They all are (the ones that matter). Opening anyone of them and doing surgery could cost 10k. If it was done right and tuned right there isn't any reason for them not to last
200,000 miles. Its just a whole lot of things need to line up that normally people don't have the
tools or
attention to detail to be able to achieve that kind of longevity, and it usually winds up being around 10% or less of what was possible, as evidenced by the OEM who did this, they setup a strategy refined over the last 30+ years to get better with time.
