do you want pollution gear is the question?
Look at this dude: Tom Wyat III he munched everything in SCCA with a snail and holley!
One truly inspiring Datsun story involves Tom Wyatt III, otherwise known as Turbo Tom. Turbo tom built a rather fast Turbo powered L20b Datsun 510 and entered in the "Walter Mitty" at Road Atlanta one year. The engine developed 275 horsepower at 21 pounds of boost for drag racing, with 250 more like it on the track. It featured at T04 Rotomaster Turbo and 4150 Holley carb set up.
As the story goes, SCCA officials started him out in class with similar style cars, but had to keep moving up in class as he blew the doors off each increasingly powerful group of cars. By the end of the day he was racing with the Corvettes and Cobras. He beat a Porsche 930 on a lap by nine seconds, and a race prepped 427 Cobra by 3 seconds. The race staff didn't know what to do, so they gave him a custom made trophy instead of embarrassing one of the more prestigious classes. http://community.ratsun.net/topic/324 ... -e-bay/page-2#entry134157
almost ls1 power with 8psi you can just use the head on an L20B block
crappy turbo choice but k24e head setup manifold can be from ebayhttps://duckduckgo.com/?q=nissan+ka24e ... b=v37-6_u&iax=1&ia=images
a canadian using the ebay manifold is making over 200kws at 16psi.
Ka24e in SCCA NA tune made 340hp and not allowed 16v but 12v head.http://ozdat.com/membersites/zac510/
Balance is the key 200-240hp atw with torque at 3-4k rpm is what makes it fun
Tom Wyatt III destroyed everything on the track with that power using old tech!
Also you are talking small wheelbase 3-4 inches less than a 510 so be careful
Pity there arent long guard and bonnet kits swap to a double wishbone 1000 setup
to lengthen the front and wheelbase of a 1200 with a small reverse bonnet scoop
the 1200 would be a Z killer in handling and out on its own in looks.
