Vortec 4200 6 Cylinder Swap into IROC-Z
It now runs...Sounds hilarious, like a ferrari V8 at full wail... no turbo yet, just getting some seat time again! I'll bolt the turbo crap on when I take some time off work, very soon. Here is a short slideshow of progress.. took a while. It's SOOO tall. Valcecover is cut down 3/4" Lot of oilpan mods but still the factory pan rail.
Oilpan is complete. 8qt rear sump. Very compact oil pickup. Slosh control. Turbo drain. Oldschool Volkswagon dipstick. Front section is 1.5" tall. As shallow as the main girdle allows.

Maiden voyage on Telegraph! Quiet as a hybrid at idle..500rpm.. and louder than my SBC was at part throttle.. 300hp Inline 6 cylinder. 4" race bullet dumped at passenger door.
Joe at Downriver motorsport wiring is a genius. Fans running off PCM, Cruise control works! Underhood pics to come! Thanks!
First gas station visit was funny. A fellow gearhead(mopar guy) asked if it was an LS1 or LT1.. Asked to see the engine bay after I explained it to him... He wanted to say.. "that's F'd up..." But he said "that's.. Different!"

10psi now, I can't get it to go any lower, even with the 6psi spring in the wastegate. 10 psi it is then.. The MAF sensor maxed out at 4600rpm so I moved it to a 4" induction tube pre turbo.. Draw through MAF now reads 60lb/min(66lb/min is it's max abilities now) of air and pulls cleanly to 6600 rpm in all gears. Limequat at Lime-swap.com is making small tweaks to get the tune right. It definately has some attitude now!
Downpipe is finished into a 4" Dynatech race muffler under the passenger seat. RPS BOV is working good also after cutting 1.5 coils off of the stiff spring.
Here is a short grainy video with 6" downpipe, NO MUFFLER.
