Default 1990 crx b18a1 swapped

Hey guys i just bought myself a crx with the b18a1 swap and the car has forged pistons and rings, 8 pax full exhaust, 6 pound flywheel, with ngk racing plugs and wires, im sure there is a few more small things also. With all that being said i would like to know roughly what the cars HP would be, im sure its not far from stock seeing it only has a few upgrades.

Pretty much stock. I would really question if it has forged pistons or not.

It is impossible to guess.
The forged pistons could be anything.
What is the previous owner had built it with lower compression with the intent to add boost?

No he intended on making it all motor, but he went to jail not to long ago so i ended up with it. They are high compression forged pistons so it wasnt built for turbo, and i honestly dont like the 6lb flywheel what would you recommend for daily driving?

They are NGK wires so technically yes racing plugs, also it came with most of the recipes on the build so yes it is in fact a 6lb flywheel and your right it sucks *** for daily driving thats why i am on here asking questions.

High compression, low compression.... doesn't matter.
The point was that if the compression isn't stock then your hp isn't stock.
If you don't know exactly what the parts are then you can't calculate or compare.

Take it to a dyno and get a few pulls and you can find out. Otherwise if he hasn't gotten it tuned, it may not be recieving anything better than stock and may be worse, unless the ecu adjusted to the changes which I doubt

How did it feel on the street? anything more than 150hp feels pretty sporty in a CRX
