Someone school me on this B18...

You’re asking noob/NickAlero questions pertaining to “boost”. 15lbs of boost on a HTA86 and 15lbs on a .50 trim are two different things. 15lbs on a K20z1 with it’s 11.0:1 compression vs. that 15lbs on a stock GSR B18c1 is going to produce different power and have different reliability.

The K series motors are pretty strong stock. There’s guys making 500whp+ on stock K20a2/z1’s and K24a2 bottom ends w/ K20a2/z1 heads and are reliable. Shit, my old K20z1 swap in my EG took a 100 shot of nitrous for a LONG time before something happened with the timing in the tune, and even then the bottom end was fine. I did Wiseco pistons and Eagle rods in that and that’s all you’d really need to do to one of those to have it be reliable. Definitely under $1,000 for the pistons & rods, then new bearings and any machine work you’d need to have done. You’d need to factor in the cost of K-Pro as well(~$800) which is a must need for tuning a K series.

Edit:
IMHO, this car would be retarded and almost not even fun with a turbo K series. You said your buddy has a K24 laying around…A K24 bottom end(stock rebuild) with a K20a2(02-04) or K20z1(05-06) head on it, with an RBC intake manifold, header, 2.5" exhaust, K-Pro and if you really wanted to maybe some mild cams & aftermarket valvetrain like Blueprint stage 2’s or something . This car would fucking hammer with that set-up, and be fun as shit at the same time. I was big into the K series a few years ago when I had mine. I would really like to build another car with a K at some point, they’re extremely fun to drive N/A. Murrdog9000 had a K24/K20 coupe that was N/A then he built it and boosted it and I’m pretty sure he’d agree with me that it wasn’t nearly as fun as an N/A K series.

Completely agree… Car was much more fun N/A
