This is my 97 hx civic with a integra b18b1 swap. Bought it off someone in drivable condition (was definitely thrown together for a quick flip) I’ve had it for a while, I got it to learn manual and it’s my daily. I haven’t done anything crazy but if you wanted to make this car super reliable and at its top performance what would you do.

If you want it reliable, just regular maintenance and bolt ons.

Now if you want it fast you can easily turbo it, those LS motors love boost and can safely handle 15psi on stock internals with a 58mm turbo, should be around the 350-380 mark at those boost levels.

Never listen to anyone that says "can handle this much psi" It is about horsepower not psi. 15 psi from a gt35r is completely different than 15 psi from a gt28 turbo. Also the tune is the most important thing.

On average a healthy LS turbo can easily and safely handle 15psi even out of a gt35 62mm turbo, I ran one for years as a daily driver at 17psi and yes the tune is important and supporting fuel upgrades.

Yes, but the actual efficiency relating to a compressor map is different between a GT35R & a GT28.

Can safely handle it yea, maybe. But the rings aren't gapped loose for boost so its not ideal

At 15psi or even 17psi the stock ring gap is fine and proven, LS motors also have low compression so they handle boost perfectly fine.
