JRSC'd engines are very reliable and pretty easy on the engine at 6psi as long as it was tuned correctly. i would have a compression and leak down test done and if all is goood in those tests buy it.

Which supercharger has a 100,000m warranty?

JRSC

the JRSC kit comes with a JR FPR and that should run his motor pretty safe as long as the timing was retarded a bit.

if you can i would recomend getting the JDM B18c1 (GSR) motor and do all the mods you want instead of someones leftover project.
