Itís time to build a new engine. So hereís the thread. As with everybody, time is tight, but I will do my best. Blah, blah, blahÖ.
í99 with less than 40,000 miles, but already on the 2nd engine.
The car- next to my SHO:
The windshield of the Miata ends below the rear deck of the Taurus!
This happened two years ago:
The block-vent is attributed to an improperly tuned first generation FMII setup. Thatís the one with the link piggyback controlling two additional injectors and retarding timing. No wideband. Old T28.
In order to get back to driving a shortblock from an NA 1.8 was installed. In addition I installed MS3/X with 850cc Five-O injectors, as well as LC-1 wideband. Stock ECU is still installed for emissions. Making that boomslang harness sucked! Stock ECU is still controlling idle, VICS and AC.
And since some of the valves were seriously bent, I replaced all 16 with Supertech +1mm valves and added Supertech springs.
This setup has seriously less power than before:
Not sure whatís happening here. Torque drops like a rock above 5krpm. I thought with the bigger valves that would not be the case. Maybe the VICS isnít working. Need to check.
This shortblock has seen better days, so I sourced another block & crank. Dropped it off at the machine shop. Hereís whatís going into it:
- Supertech 8.6:1 pistons
- China rods
- ARP bolts
- Super-awesome harmonic balancer
The block has been bored and decked. The machinist asked my 3 times if I was certain about the 0.004" piston clearance, but I held my ground!
Next week itís time for checking the mains (was waiting for the ARP bolts). And then itís assembly time. Iíve never assembled an engine, so Iíll try and document every step, looking for feedback on what I did wrong.
Further down the line I hope I can afford an Artech/EFR setup. I think this engine should be able to take it.
