ok.. i'm building a 18 mile race car and here is my setup
L28etP90 Head and felpro head gasket
stock 3.54 diff
stock internals and head.
stock turbo
stock 78 wiring and injectors.
10:1 FMU
15 psi of boost.
Butt dyno tuned.( AF ratio ,Fuel pressure and boost gauges)
my best time so far was 8.3 with slicks. 1.8 60ft
i want to make this car as possible with stock internals, my next buy will be alcohol injection,merkur injectors and a bigger turbo.. i don't have the knoledge to install a stand alone system.I'm a college student in a third world country(tijuana Mexico), and i love z cars..
i would like to know what differential ratio would be the best for 18 mile racing(i'll weld it), my budget is really low but i can buy l28 engines for less than 100$ us dollars .. help me choose the best setup to hit 7's ..
