A lot of great work and cool mods had already been done to this motor when I pulled it apart---most notably to the head---but it is pretty clear that the shop or individual that put it together before I owned it did a very sloppy job. I initially tore it down because of a rod knock, but I found scored lifters, a badly rounded-off and uneven cam, broken rings on two of the pistons, and a nearly frozen oil pump...this thing shouldn't have lasted as long as it did...
The current build now consists of:
B21 pistons, rods, and 8-bolt crank.
Milled bock and head to achieve 9.25:1 compression ratio from an F head.
VPD Street Performance cam.
IPD Hi-Rev valve-train kit.
Steel and aluminum timing set from VPD.
Housings machined for rubber crank seals.
Ported head with larger-than-stock valves.
IPD header.
Toyota alternator.
Crane Cams optical ignition.
IPD adjustable F.I. box
Lightened flywheel.
240 pressure plate for a stronger clutch.
Should be putting out about 160-170 HP---maybe I will dyno it once it is broken in...
Here are some shots from the build:
