Hank EFI-DIY From there to the tail pipe its a 4" system orginally off of a duramax. Got 25' of pipe, hangers, muffler all kinds of bends . It sounds like you are using a stock Duramax muffler? If so, that will cause some back pressure & cause your turbo to spool up slow. Two cents thrown. MBHD I think its an aftermarket exhaust - the muffler is a straight thru glass pack. . _________________________ 51 GMC 4.2 turbo Can't solved today's problems using the same technology/thinking that created them

inline300 inline300 Active BB Member Registered: 12/13/04 Posts: 460	Reason for no aftermarket, is this engine was only stuck in a big ass SUV, people in general wont make the transition from, take the kiddies to soccer practice and get groceries to, hmm...I wonder just how fast I could get the kiddies to the field and to the store and back with the old six banger...:D Now if GM woulda pushed their twin turbo SUV prototype in everyones faces, as they sat in the dealer showroom waiting for the salesman to come back from speaking with the "manager" as to whether they could give them the "deal" of the day and shown them how 400+hp was tangible...then things would be different and much more inliner friendly. $\:\)$ Sad part is, the gen III v8 in a ligher/aerodynamic vehicle, this is the higher hp LS1/LS2 versions, actually gets really nice mpg, 30 isnt out of the realm of possibility.

Look where GM stuck the 270 & 302 and our forerodders found them and scared the stuffin' out of a generation of V-guys. The shame is that many of us seem to be late picking up on the potential of the 4200s. I agree with Marc and wonder why we bury our heads in the casting sand of an out dated design. Tradition?

Hank Active BB Member Registered: 09/23/04 Posts: 4550 Loc: Ca	Just thought about the comment about the newer 06 & newer head flows 50% better on the exhaust, efi-diy,,you stated it will help w/the turbo spool up better. I disagree,ports being bigger ,less velosity,slower spool up. A few ways to bring the spool up is by Nitrous,smaller turbine housing (I recommend),or a loose converter,not being a BB turbo,3500 stall is aprox the min. stall needed,that's if you want to be able to boost launch.

Smaller turbine housing - good chance this will come to pass Higher stall - don't think I'll be able to get away without it - maybe a 100HP hit it'll shock the coverter enough..(maybe boom $\:\)$ ..) Last time out it was just a 20HP shot. AS for the ports for spooling yes and no - yes velocity is a good thing, but you also need volume... the small ports are so darn restrictive that I'm thinking the its choking the engine pretty good. We'll find out once the built engine goes in. Once a gas stream reached sonic velocity - its really hard for an orfice to pass more gas. The other item that you wouldn't know about is the internal passages in the turbo manifold are sized for the 90% of the later port. So on the early head the velocity falls off. So with the later head the gas stream will have to increase velocity as it enters the manifold. Worst case it'll be slow to spool but run like a raped ape once the boost comes up...

The fabricator that finished welding my oil pan is will to build headers for the 4200 if he can get 15 committed orders. Mild steel or stainless. 6:1 straight tube or stepped pipe, or, 2 x 3:1 >> 2:1... With enough demand the parts will follow.

efi-diy efi-diy Active BB Member Registered: 11/21/04 Posts: 1386 Loc: Calgary Alberta Canada	Went to the public scale today I was kind of surprised at first... 3800#! << porky Then thinking about it.. added turbo, turbo manifold, intercooler, 4" exhaust system out to the back bumper, charge air plumbing, and NO2 bottle. If I remember correctly I think with the 292 the truck weighted 3550# but I never wrote that number down so its fuzzy. So at 3800# and 98.3 mph == 280RWHP >> 360ish at the crank. Density altitude was around 3800' so I think this HP # is about right. It line up with what the goofy chassis dyno reported. Before I installed the turbo the truck ran the same ET with the stock 4200 as it did with the tricked out 292 (ported lump port head big valves, cam, offy, holley 600, & headers).

Beater of the Pack Beater of the Pack Active BB Member Registered: 10/06/07 Posts: 2492 Loc: Northern Nevada	Here are some photos of my friend Dan's '64 Chevy pickup with a 4200. I took these in May when he had just got it going. I saw it Saturday but I didn't have my camera. The engine compartment is cleaner and more complete now, ( wiring etc...) He got some help on the wire harness and computer. I haven't got a ride yet, but he is really happy with how strong it is. He says it loves RPMs and ignores the Sierras. His only problem is that he can't get it to warm up without overing 1/2 the radiator. Marc, He wants to know how the Black Opel guys run the distributor. He made major mods to the front cross member to accommodate the pan. My '68 frame is the same. I'm sticking with the 292 for this one, but I'll check the '90 Burb 4X4 frame and see how that would work for a future truck.

efi-diy efi-diy Active BB Member Registered: 11/21/04 Posts: 1386 Loc: Calgary Alberta Canada	Beater, The opel does not use a dist. its running 3 wasted spark coils driven from the MS system without a ignition control box. The ignition is triggered off of a 36-1 timing wheel out of a 92 escort. Rather than mod the cross member I'd modify the oil pan using 2 I5 pans to get a rear sump. My truck is running - not driving it much now - a bit cold without heat. More focused on completing the real turbo motor, which is trying to say the least. Seems murphy has signed onto the engine build team here...@@#$!!@# its a lesson in patience. _________________________ 51 GMC 4.2 turbo Can't solved today's problems using the same technology/thinking that created them
