Call me Mr. Smooth, I guess!

The Megasquirt guys did this a decade ago.... the consensus was the ONLY capacitance necessary was provided by a small engine gas filter. Anything more and the MAP started getting sluggish in response.... and if you have sluggish MAP response then you get hesitation. There IS such a thing here as "Too Big" and the brake booster is it! You DO NOT want a separate reservoir with the MAP taken from it!!! That is TERRIBLE and when you put a megatune on it and datalog you start seeing the disconnected lag that results in longer larger TPS Dot enrichments to cover the lag that you normally wouldn't have if you piped it properly. Let me put it this way: Look at a GM MAP sensor, or the old Honda PGM FI MAP sensor and see how they are plumbed. Yeah, I know, a common plenum manifold, but the MAP sensor is RIGHT THERE with maybe a 6" hose. The impulse spike from a dedicated runner manifold can be mitigated somewhat by using a BALANCE TUBE, and taking your MAP there but if you are running Carbs it becomes a BITCH to synchronise and mixture adjust the carbs properly then unless you make it easily isolated... Really that's the best compromise, and most people run the balance tube as it makes a vacuum tap easy for A/C etc... But if you are running without one, then you want a dedicated line and a variable orifice which you trim for best response using your datalogs. WOT vs MAP change, %Throttle Angle Change vs MAP change, etc. As stated, most guys found sticking a Briggs & Stratton or Weed Whacker fuel filter in the line worked out just right to dampen the pulses but not add so much volume that MAP Lagged. "BEEN HERE DONE THIS!"

JWT 450 Kit had that name for a reason...

I said LIKE screwing a Donkey, or a Sheep. I knew bringing sheep into this would get a Kiwi's attention...

A storage sea container can be very easily climate controlled. I know someone who has 40'ers in their yard where they store Cotillion Gowns and the like...right next to his machine-shop barn and Deisel Mercedes Hoarde... If Miss Universe / Miss America competitors can trust their gowns to a climate-controlled container....your car is in good hands! Though the carpeting is probably overkill...

Dan Hyusman and Strictly Foreign is not...

The booster is a big source of capacitance...if you are using the brakes there is a draw in the line which can affect the readings. Better to take it direct so no skew whatsoever enters the system. Watch what happens with a MAP straight on the runner, then with a Briggs & Stratton or McCulloch fuel filter in the line. The capacitance changes how the MAP reacts. Same for the brake booster which is indirectly a vacuum using device.

3.70 gears... 2nd is 60 mph at the top of second. Anything after that is illegal anyway...and the car will double or triple the speed limits in most any state. My 3.36 ran 2K at 50mph in 5th... YEECH! Also the E-Motive numbers above are "published"--the actual numbers are quite different, it had a bit more than 750hp at 7500 and 21psi... Those were just enough to impress the mag writers of the day. Real competition the boost was higher as was the rpm ability of the engine. It's really not relevant to this discussion.

I've no clue, it's Priddy's manifold!

Nothing is wrong with screwing donkeys, that's my point. And a Z31 system is not an L28 ECCS, I would say that's more sheep or monkey than Donkey... Not that there's anything wrong with that...

Clear lacquer... There was a clear electrostatic coating as well...

Hahahaha! More and more people are telling me that! Having read the life chronology of John Muir (not the nature photographer, his descendant who was an engineer at Lockheed and "tuned out" to become a long-haired VW mechanic -- and wrote 'How to keep your VW alive! a step by step guide for the compleat idiot') this may be in the stars!

The way I gauged VW Shops is I'd take the Bus there for a valve adjustment. If they didn't want me to leave it overnight... I found a reason to move on... In orbits, from my apartment in LaHabra I ended up with a place next to the In-n-Out Burger at Palm... They moved to Oregon...so I went back to doing it all myself!

Exactamundo!

Asking a shop for references is a normal course of business. If they have references they readily give you, that's generally a good sign. The places to get feelings about are places nobody talks about, and where they talk big to you but can't give you a previous client list. In LA, some shops won't give out celebrity contact information... But when you see Jay Leno in the back of the shop with dirty hands you get an impression that likely Jay got his name from somewhere reputable! I don't know how to relate that to the middle of the country. I guess if you see the cast of "Duck Dynasty" in there picking up their cars...chances are pretty good they do extremely high line work.

Blame DaveK!

AEM has some E85 compatible pumps available.

You are going to read the above...look back at the photo you posted and have a Homer! "D'OH!" Before our very eyes....LOL

NO! You, my son, have missed the forest through the trees! Not the down pipe, but those two little clamp things to the RIGHT of the huge down pipe accordion bellows...you know, the ones in EXACTLY the same place as on your manifold? THOSE bellows and clamps are the ones JeffP used. They fit and as of last year were still available from MB.

If you can't find the Nylon66 adapters, I found out my local hardware store has a web store...PM me if you need the info...but you should be able to find them locally...

No, they are not. The physical dimensions are very close, but the fuel pickup is the big difference. The 260 has an 8mm (5/16) fuel pickup, 6mm return The 280 has a 12mm (7/16") fuel pickup, 6mm return For the life of me I can not remember if the J-Bolts were from my 260 or the Donor 280! On a 240Z you ABSOLUTELY need the longer J-Bolts from the 280Z to get the tank straps to fit. I don't THINK that was the case on my late 260...but if you can manage to also get the bolt set and/or straps from the 280Z tank you would sleep easy knowing if nothing else you have spares! (My straps were cut in half to remove the tank...so they became "end donors" being welded to a 304SS Strap with 309 TIG Rod If you are OK using an adapter on the EFI tank to the smaller line, then go ahead, use it. I put a 6/75 EFI Tank in my 12/74 260Z when I did the Turbo EFI Swap. As I recall, there may have been vent hose differences, but caps, plugs, or simply som Nylon66 barbed hose transitions (5/8"x1/2" or 5/8"x3/8" depending on what fuel line size you can tolerate for your vent hoses...) and you're set! I convert all those large 15mm vent lines to 3/8" with the adapter fittings (same as used on the Z and other Datsun stuff of the period.) I haven't used a stock set of vent hoses in 20 years! Cheap to do, and leaves those vent hose openings for running trailer harnesses through, etc... Tank easily holds 5psi leak test pressure overnight, so SMOG check pass, and the fuel lines don't seem to deteriorate as quickly as the original braided covering hoses do!

Like I said.... Intellectual honesty prevails, I'm not going to debate it. Anybody who has taken a "perfectly running" L28ET and swapped to aftermarket EMS RAVES about the drivability improvement. To a man or woman, they can't believe the change. It's a different car and almost every one says "I regret not doing it earlier, I'll never go back." At this point of the project, having NO EMS whatsoever, nor harness, nor AFM, nor Spark Control, and looking at the prospect of BUYING every single component....why compromise on sluggish, disconnected throttle response, 30 year old (at the newest) ECCS box with dry caps skewing the signals, etc...instead of just getting an Aftermarket EMS once and being done with it, and being able to expand to 450+HP on that very same box? If he had a running L28ET and was doing a swap, that would be different. But he doesn't and he's going to have higher compression than the ECCS was calibrated to run with...not an L28ET! It just doesn't make sense given that starting point. And this coming from someone who's got intimate knowledge of the JECS ECCS and retrofitted them to other vehicles when Aftermarket EMS was a cost-prohibitive or unavailable prospect. It was near the best for its time, but it's hopelessly outdated and a relative poor performer against even an MS-1 with basic 8x8 tables, much less the expanded fuel and spark mapping in MS1 on MS-n-Se (or an SDS) the two entry level EMS's that fall quickly to mind for the beginner. If this was 1989, maybe. 2002? No longer! In Colombia, it's not uncommon for pubescent boys to take up and consort carnally with a donkey. Some may have several donkeys with which they have regular sexual relations, one reason given is it increases the size of their sex organs. Culturally it's accepted, and when they eventually find a female, they move on and leave the donkey behind. They realise it was only a one-dimensional release, and that a relationship with a human being is so much more fulfilling on so many different levels. I chose to leave the donkey (JECS ECCS) in my past, and suggest since he hasn't started, to not even waste the time. If someone chooses to screw donkeys, I will not stop them, but having moved on myself (MS Group Buy #2, 2002), I will not let them colour prospective newcomers into believing it's anywhere near the same experience.

Pfffftt! FLYWHEEL LIGHTENING THREAD CLICKETY CLICKABLE LINK

Not E or C... What was available in1983? Were there E's & C's then or were there just 280D's? SL's were there... Maybe an S... I believe it's on Jeff's website. Going to a Mercedes shop to look at microfiche and say "that looks close!" Or maybe a junkyard? That's what Jeff did to figure out what fit... Then he went to a dealer with the VIN information of the car in the Junkyard and ordered a few new ones along with their clamps. From what I recall it was an "exact fit" after a slight stretch of the bellows for axial length adjustment...which may be the case on the MB installation as well. This isn't rocket science here, this is basic Junkyard 101 engineering, take a likely prospect and see if it fits or you can make it fit. Beats the alternative of an NC lathe machined part that will have to be copied from a parti don't have access to measure right now!

Now with that kind of response lets hope their stocking system lays in another ordering bigger quantities!
