The new NISSAN 350 Z is gonna be desighned on the same consept . it is electronically assist turbo. The turbo will spool up under electronics untill the exaust takes over, which means no turbo lag at all!!!
Alright ,I assume you have a turbo engine . I usually run high comp. engines but there is a difference in exaust. I use a try-Y 180 degree header ( extractor ) design . 4-2-1 . You can use bigger & longer tubes which will give you more torque, which means wicked ecceleration. better off the corners!!
I am a forklift mechanic here in the U.S . The only ones Iv'e seen using the Aseries was the old Datsun forklifts. All the NISSAN forklifts have been using the H-20 for years. very good engine . NISSAN never seen a reason to use any other. Even though the EPA has now gotten involved & have to meet the same standards as cars, they still use the H-20 engine with a redesigned headfor emissions.We are getting 33 new ones in a couple of months .
The question is ------ is this going in a high performance engine or stock? You can stretch the spring in a stock oil pump & will give you more oil pressure ---but ---- too much oil pressure in a performance engine can also hurt you ,not in oiling but performance itself ( small figures though)
