First Tank Results CRX HF/DX
First off thanks to all for helping me with my questions to get this thing running. It was a short fill so we'll see. 125 mi 2.6 Gal. Filled to first click on the lowest stop on the fuel nozzle both times same pump 48MPG.
This is with a d15b6 head on a 50K JDM D15B (DX) shortblock. I drove like someone with a new car, revs all over the place, 70 on the freeway. I think with easier drive technique (light hypermile), some low rolling resistance tires, synthetic oil, I'll hit at least 55 mpg. For the record this is not a unique engine. The 92-5 CX had the same head PM8 on the DX block. |
Looks pretty good so far, you should be able to get those numbers up no problem.

So the valve reliefs on the pistons are not a problem? I would think that running an 8 valve head on a bottom end with valve reliefs for a 16 valve head is going to cause some piston/valve issues.

Had both bottom ends sitting side by side. Everything about them was the same except for the two extra reliefs. Since, as I understand it, the piston parts are unavailable at this point, using a DX block is pretty much the only choice available if the pistons are shot
