Hello all,
I've had a 77 280z for a few months now. It's got a 75 L28e motor with the non exhaust lined head. Since then, I've converted it from automatic to 5 speed, 3.9 R200, decent paint job, etc. My friend and I were getting the car ready for a long trip (1500 miles) doing routine maintenance when we heard what sounded like rod knock. Well, a 2 hour basic maintenance trip turned into a 10:30AM to 5:30AM bottom end rebuild. This was 3 days before my 1500 mile trip. Regardless, the car made it with no issues!!
Essentially, everything has been touched in this car except for the wiring. It runs great and is my daily driver. Now I'm looking for some more power. I've already done the basic stuff (auto to 5 speed, 3.9). I do like the L28 motor, but I have no issues swapping in something better. I am not looking for a crazy drag strip beast, just maybe upwards of 200whp with decent gas mileage (20+ would be great!). I know generally power and gas mileage don't go together, but I know some of the Chevy V8's can get you 28+ on the freeway.
For a budget of $1000, what is the best way to go? From everything I've read, it seems an L28ET may be the best option. If I don't do a swap, will any upgrades to the L28 give significant gains within this budget? There are still intake, headers, megasquirt, cam, headwork, etc.
My goals are a 'quick' daily driver, so I would prefer to keep the power band lower rather than higher. Torque improvements would also be nice.
I'll be happy to give more information if necessary!
