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! :eek:

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.
