hey how you doin mate. look i know im a newbie and all 2 dis site but i had da same problem. wen u punch it n back off n hold the clutch in does it feel like its gona stall on u and come back 2 normal revs?? and da splattering??? ok i tried bigger fuel pump, coils, sparkplugs, etc etc etc. when i wen back dey narrowed it down 2 da vct. while dey have it on a dyno if it does it again get em 2 pull off da plug 4 it n play around wid da timing.
just a hint. it took me a month n every day at da work shop 2 get em 2 find it.
i have a r33 wid hybrid front mount single stage boost controller, bov, aftermarket fuelpump, platinum spark plugs ( which do make a better spark in my case ) that are gapped at .8.
even with da vct not connected i pulled 213.2 kw@tw. so im guessing u will blow way over wat u think
anyways good luck wid it n hope it works out well 4 ya
