Frayz's V7 Prodrive Edition Impreza STi - "The Bomber"
Tonight I managed to get 5 min to spend on the motor. So the cylinder heads have been fully assembled. Rewashed, final inspection, measure of all valves and guides and final cc check and then assembly of the valvetrain.
Everything was in spec and the final cc of the chambers came in at 54cc dead for all 4 chambers.

As promised ive always said that when the time is right i would just go ahead and put the engine together. Well today was that day and ive assembled the short motor.
So within 48 hours i have a fully built set of heads and a built shortblock. lol
I'll get some pics up when i can, but heres a taster

Okay guys,
Nice to get some time to spend on the short motor yesterday. So here are some snaps from along the way.
Block, crank, rods, pistons were all hot washed and inspected and allowed to cool. (Soak to room temp) Rods were assembled to crank with new ACL Race bearings. Bolts were torqued and checked for stretch. Big end side clearances were measured.
Block was then split and main bearing liners fitted. Also ACL Race series.
Orings were put in place and crank lowered in place.
Block was then sealed using Loctite 5910 and torqued to spec. Crankshaft endfloat was measured and rear main oil seal was fitted.
With the block torqued i gapped all piston rings, Top comp set to .40, Napier set to .48 and oil controls were set to .38.
All rings then fitted, gaps orientated and pistons installed. Turnover torque was measured. Wrist pin access plugs were installed along with the rear breather plate.
I wanted to fit the oilpump too but i seem to be missing an Oring, so that will have to wait.
Now the motor has been bagged and sealed and will be placed on a stand for further build.
Compression heaights willnow be measured and i can order head gaskets formy desired squish and CR.
So nothing too exciting but progress all the same
