My 4AGE Story... (56k Warning)
So, my 86 has been off the road for a few months now but its nearing completion and you guys might be interested in the story of whats happened over the last few months.. So here goes!
I finally got my Toda Cams (304/288 8.5) and ITB kit on the engine and sent the car off for tuning with my Engine guy, a few days before a drift day.. Here is how it looked at the time after some fettling: ![]() The car was ready for tuning on the dyno and it made 150hp, with a little more to go (compression issues due to bore wash was hindering power a bit).. Then... ![]() ![]() Damn, spun a crank bearing while making a power run ![]() Final spec of the engine is: AWT (Angel Works Technologies) competition high torque port development, hand blended valve seats with compound radii, extensive chamber work to match piston crown and quench area and allow good flow at low lifts and with piston at TDC. AWT custom Camshafts. 282/278 deg duration, 106 deg LSA/peak timing, 3.8mm @TDC inlet, 3mm @TDC exhaust and 12mm lift total (50%more than the old todas!!!). Arrows F1 Team solid lifters with daimond like coating AWT custom forged 1mm oversize pistons with custom crown design to best enhance burn propagation, compression ratio, quench area, valve reliefs which aid flow at low lifts and active mixture conditioning, coated skirts. Note in the pictures the before pic which is the bare machine finished piston, they are then hand finished and blended and textured, otherwise alot of tuning potential is lost in terms of EGT, ignition timing (run as low as possible) and how lean we can run it. It really helps starving off det/knock/pinking, you turbo boys should all be doing it! Rods, crank, pistons, flywheel, clutch camshafts all lightened and balanced by the best in the business, not your average balance job. All this running though the existing OER throttle bodies, which have been modified to flow much better with less turbulance and expansion pockets, loosing less energy in the process. The Pistons: ![]() ![]() ![]() After the Block was bored out and all the components installed, 12 thou was taken off the deck because of water damage from a blown head gasket. The head work was started the day after.... Driftworks - JSPFab.com - DangerStyle - NightSpirit |
