It is engine related, but it isn't a technical question, so I present it to you here, for whatever it's worth... The "ported" (emphasis " ") heads that came on my car VS. The "cleaned up a little" heads that came on another 109 I bought recently. Just goes to show you, life is all about...

56/56 turbo, turbonetics .63 turbine housing, Garrett compressor housing. Bought it last year from a board member new and ran it about 500 miles just on 93. Worked well, spooled very easily, just had some compressor surge with my big front mount. Moving back to a bigger one now. $600 obo with...

Yeah I've ran a 10 psi sweep of boost pressures testing with my 5.7, and can keep it pretty close by adjusting the fuel in the chip. it is nice to have that much room to adjust. I wouldn't mind just having it able to lean itself out a little when the weather changes, I wouldn't want to leave it...

Interesting. When I breezed through the instructions pdf earlier it sorta just read like you adjust your tune via the axis instead of using the normal chip method. Not seeing much about it correcting on its own. Definitely sounds like a good setup, though. Looks like I have yet more reading to do...

I had never done any reading on the AXiS until just now. If I understand correctly, it will correct somewhat based off the maf? As opposed to my regular 5.7 which just looks onto "255" at wot and gives however much fuel, timing has been set. I was just looking into 6.1 because I already have...

In my research I've found a lot about the 6.1 chip, but not this one little detail. Does the chip need to see an actual MAP reading via powerlogger to make the mid-boost fuel corrections, or is it just a calculation based off of rpm, tps voltage, wideband, etc? I already have PL, and I already...

you better hurry up and just put it in the car, or I'm gonna beat ya without alky :sneaky:

looking for a poly passenger side mount, already have a good hr driver side. Also looking for either valve cover spacers for stock covers, or a set of taller valve covers, depending on price.

Rockers came in this morning. Thanks Mario!

It is a 20 bolt block like the 109, so they should interchange. The strength is the question. I wouldn't have been surprised if they were about .060 in the hole I meant, but not .085. I Suppose they may not be factory, as they are marked "standard". Very much the factory style of dish...

I've read that the 14 bolt hot air blocks had a taller deck height than a 109, is the same true for the 140? Are hot air pistons identical to ic? I ask this, because upon teardown of my 140 equipped hodgepodge of an 87, I've found the pistons sitting ~.085 down in the hole. They're factory...

Looking for a good short block before I dive into this one instead. Don't need anything crazy, stock one would be fine.

I don't know, slow, and heavy. Never weighed or been on a dyno, full weight hardtop, power windows, locks, ac, spare, etc. Only got to mid 7s/high 11s with my ogre self in tow before the 200 let go. I can test back to back at the same low boost, but it won't be apples to apples, as the converter...

A 4l80 with a very basic, near-stock rebuild will handle power approaching the levels of most 200 builders' "level/stage 2" unit all day long. Those are almost always $3,000+ builds these days. Mine was built locally, with nothing more than dual feeding direct and the Superior kit. It cost me...

Some seem to be thin enough that it's a non-issue. The steel trans-dapt brand one I used is about .310" thick, and it came with a locating spacer for the converter hub, and a set of machined washers to make up the difference at the converter bolts. I would definitely get longer dowels for the...

Updating to avoid wasting people's time, turbo has been found.

Gap is .030", should be no issues with the tr6 and late model 4.3 coil pack jumping that gap until much further than I've gone, haven't been over 20 psi yet. Agree with your analysis of force against the valve, that's why I mentioned it seemingly being worse with more boost. It does act how it...

No heat sink, it's the v6 truck coil, waste spark setup. Still, I haven't heard of a bunch of issues with them, so I think you're all on the right track. I'm guessing I was 'marginal but getting it done' pressure wise last time I was racing it, but they have since worn in and weakened. The cam...

Autolite 25 platinum, because that's what was around. NGK ur5's were doing the same thing, and also NOT doing this before the car sat. Both are resistor if I'm correct in my understanding.

Probably need replaced by now even if not the culprit. Good a time as any to put the rocker shaft braces on I bought eons ago, eh?
