Last friday I was on my way to work and at the last stop light I threw the #1 rod straight through the block AND the oil pan on the 1-2 shift. First I though it was the differential exploding and spitting a spider gear through the case...but I noticed the engine was missing and barely running. Then this big a$$ floppy piece of metal come flopping out from under the car and smoke started coming out of the hood so I knew what happend then. I shut her down and drifted all the way to work. It appears the rod bolt failed but I haven't torn the rest of the engine out yet. The piston is still in the bore at TDC...which could mean bent valves, but the spark plug isn't bent or even have ANY signs of detination etc...
The stock bottom end w/ the small B6 rods took 24-26psi on a BIG GT30R turbo for over 10,000 miles! I'm impressed they help up that long, but now now its time to quit playing around, put the BUILT bottom end in that has some compression to it and gun down 500+WHP turbo only. Then comes a custom 1 off ported head, intake manifold and MONSTER Intercooler finished off with lots n LOTS of nitrous!!!!
Hears what happens when BIG HP throws a rod with NO detination....

about 20+psi @ 7600RPM or as soon as I hit 2nd gear...went by REALLY quick so I'm not sure exactly which point it broke. Can't wait to put the other motor in with the LSD!!!! It should rain pure terror on the street and pull low 10's all day in the 1/4 mile!

Yes it was a B6T...out of a Capri XR2 Turbo. I rebuilt the bottom end with off the shelf Speed Pro Bearings and Beck Arnly Rings. It was sealed up by a Fel-Pro MLS Head Gasket, ARP Head Studs, & Copper Gasket Maker on every thing else. We modified the oil pump for increased oil pressure put in a set of the Corksport Turbo Cams (Web Cams). And the rest you can see in the engine bay!
The B6T's can have 2 different size rods in them. The ones out of 88-89 323 GTX's have VERY beefy rods...larger than the 4G63T's rod base! The later motors came with the smaller rods also found in both B6 & BP series engines. The B6's & BP's can all use the same rods because they all use the same rod length, wrist pin diameter, and crank journal diameter. The rods I broke are the small B6 rods, also found in the BP's. The part I believe failed first is the rod bolts.
The car was estimated to be making around 400WHP and would spin the 225/45-R16 Yokohamma AVS ES 100's even up at 120MPH! I upgraded to 245/50-R16 Falken ZIEX ZE 512's a while back and it still broke traction through 3rd gear until I put the muffler silencer in....it still spun to 70mph in 2nd gear! The gear ratios are HUGE with the 245/50's!!!

That was back when I was running the stock B6T setup w/ the B6T turbo and manifold. Yes you do want your MAF before the turbo because it isn't a blow through MAS. I'm not sure if the DOHC MX-3's MAS sensors are able to take blow through pressures or not...I wouldn't recommend it unless the hot wire sensor element is pretty hefty. The MAF cars can be upgraded to a 2nd gen RX-7 MAF which becomes a major bottle neck at around 300HP.

If you want man when I take out my b6de for my bpt. I will sell you my motor if you wanna rebuild it. It has 160,000 miles on it. Lol this way you don't have a hole in your block and you can get back on the road.
