Just get the B18c5 swap..
Its worth it... You get the LSD tranny which is $1200..
You'll be much happier overall... With just boltons, you can make close to 185 whp in a B18c5.. In a hatch, 185 whp will run 12s...

That would take way work and money to to in a B18c1..
Plus you dont get the LSD tranny..

Trust me.. B18c5 is worth it...
