The problems you listed on page 25 are mainly caused by no speed sensor or the one that "fools" the ecu. Did you rig up a 5 pulse speed sensor? The vss probably needs cleaning as well.
The computer chip can be hacked and changed. I have yet to do the svx but I have done a obd1 for the 2.2. I will need to did up the info on the chip set. BUT I think the performance end is pretty good.

I didn't read thru the hole post. I will later.

Did you need an extra ecu harness? I probably have at least one.

Hi Jeff,

Nice to hear from you. Hope all is well. I hope I describe this correctly...

So when I had no speed sensor hooked up at all the car just had an occasional stall issue and an idle issue, which I think is common since the SVX is automatic. If there wasn't enough load the car would stall. Late last year I took the speed sensor that I had saved from the SVX trans and installed it in the 2006 WRX trans I am running. Screwed right in just fine. Although I noticed a huge improvement in the idle and some behaviors, it seemed to bog down and stutter, especially when I opened it up, but also on takeoff from a stop. It's a '95 so it doesn't have that '92-'93 issue that some might be thinking of where the car bogs down off the line. I was wondering if it was just a loose wire or something. Maybe the IAC valve was sticking...something like that. I think there are two speed sensors on the SVX. Do I need to rig something else up too? Would a different VSS be better?

Steve (914forme) was looking for an ECU harness, but if you have MORE than one I'd take one too. Happy to throw some $ your way. If you just have one Steve is welcome to it. He deserves it after welding about a mile of sheet metal (IMG:style_emoticons/default/biggrin.gif) .

Damn sure sounds like the VSS is screwy. I'd change it out but I don't know whether it's a mis-match or simply defective. (IMG:style_emoticons/default/confused24.gif) Wonder how you can test one? (IMG:style_emoticons/default/idea.gif)

Thanks good to be back. Iv been helping a guy with the 95.5 basterd child swap into a type 3.
Is the vss all the way closed just sitting? I would pull it out and see if crap has cloged it. Second the vas is conected to the outside port on the switch valve?

As far as flipping the manifold hang on .. I am working on a fix for the svx to fit the vanagons and the 914. I just did one for the type 3 2.2 but I'm not sure on the svx. I'm working on an extra manifold as I write.

You have inspired me to get this think back to smoking tires.

[Chris H.]

I'll pull it and shoot some pics tomorrow. I wired it up exactly as it was before using the stock wiring harness end.

Let me know on the manifold situation! Sounds like something quite a few people would like.

[Cracker]

Chris - Sorry for the late reply...I don't have any experience with the 5 speed. Several of the members here have them behind Subbies I believe. The ONE thing I do know is they have a smaller R&P - if your car would ONLY be a hot rod/street car. I highly doubt you'd ever have a problem. I don't know if the adapter, flywheel and clutch pack is dynamically cheaper than the 6-speed - maybe.

It is not generally a cheap way to go (Unless you're are BOB)...he can make anything happen for nothin'!

All the best and enjoy what you've got!

Tony

How's the gearing on the 5 speed? Go big or go home? 6 speed or nothing?

[Chris H.]

Hey no problem Tony. I thought maybe the adapter would be a lot cheaper on the 5 speed...if not then the 6 speed seems like the only way to go. Is the adapter really that much more complicated that it costs $3k vs the usual $550 or so? Must be.

[Cracker]

Again, I don't know if the adapter, flywheel and clutch are different between the two - someone here surely can chime in (who has a 5 speed version - same as the audi/vw variants). It is NOT just the adapter plate - that price includes the entire assembly (adapter, flywheel, PP an clutch). For the 6 speed - it is quite impressive and much more robust than the standard set up.

It is yours Chris, for what I am doing with the car I would like things like launch control etc.... That being said I am still really thinking about SDS, as they have done EG33s and turbo EG33s.

So I am ditching the intake upper section at a bare minimum. Trying to determine if I am going single manifold or ITBs. Part of me really wants to do ITBs (IMG:style_emoticons/default/happy11.gif) But Single manifold is a lot easier to turbo if I wish to do that latter. Maybe build both as I like to build

[a914622]

So it looks like the manifold mod is a little more than I was going for. I was going to cut the Tbody surface 90 deg to the secondary manifolds and install keenserts to bolt the throttle body back on. Not enough meat on the svx manifold. I'm going to make a plate and see if the welder can/will spark things back together?
It should move the Tbody .5 inch froward and point straight back not up and back.

I pulled an extra vss out of the stash to check the bottom bushing. It had a lot of wear and I suspect was hanging up or leaking air.

[motoTrooper]

Hey there! I've been avidly reading the EG33 builds here and wanted to comment and thank you all for your pioneering work. I am planning a conversion but into a different car -a 1977 Lancia Scorpion. Seems apropos as like the 914, the Scorpion was a weird cast-off stepchild with a lot of potential. Just needs love, understanding, and an infusion of triple the power to show what it can do...

Best regards,

Sounds interesting Jeff. BTW...the VSS you're describing doesn't sound like mine.

Here's the one I am using.







Screws right in to the WRX trans but it's from the SVX trans. The T shaped part spins which is the speed indicator. It has 3 leads on top. Power, signal, ground. seems to spin OK. Don't see any bushings unless they are missing? Maybe I need to lube it and put some RTV on the threads to make sure it gets a good seal on the trans.

Christopher,

I'm familiar with the Scorpion. Very cool little car. Not many left out there. You're putting an EG33 in it??? Post some pics!

The Scorpion has a transverse layout if I'm thinking correctly. An ideal candidate for an MR2 drivetrain or a Honda B16-18 setup- that little bugger would fly!! Good luck with your build! (IMG:style_emoticons/default/w00t.gif)

[76-914]

Chris, can you look inside the trans to see the where it seats? I ask because I don't remember if mine looks like that on the trans side. Then again at this age I can't remember what I had for breakfast.

[motoTrooper]

The Scorpion I got is a basket case. I have run the mental gamut of putting in an Alfa 164 V6 (cool but they have their own issues and it's been done repeatedly), a Honda/Acura K20/K24 IL4 (powerful & cool but a four banger and sounds like one), a Honda V6 (not a total fan of the transverse layout), the Subaru flat 4 (they all sound like a subaru flat 4 but have the longitudinal layout I like), which brought me to the EG33 (strong, smooth, low center of gravity, balanced longitudinal layout, and sounds like a Ferrari BB512!) The EZ30's appealed also but are more expensive as I'm sure you're aware.
I need to fabricate all the floorpans and address rust issues too so it's going to be a long row to hoe. I'll happily share my progress if you're interested. I love modding vehicles, I've built a few cars and a bunch of motorcycles. I like the friendly camaraderie that I have seen reading through the threads here.

Here's what the other end looks like Kent:



The T piece fits in that slot (or it won't screw in). The WRX one looked pretty strange on top. Couldn't tell where the wires went. It was just a round piece. The lower part was the same. It was made of plastic.

Christopher, post away! We like pictures (IMG:style_emoticons/default/biggrin.gif) . FYI the EG33 is fairly heavy for a car of the Scorpion's size and weight but if you like it, go for it. A VW VR6 might work transversely... (IMG:style_emoticons/default/idea.gif) . Only if the longitudinal layout didn't end up working out. The Audi 2.8 is also a nice small motor (not the narrow angle V6). Could mount that to a Boxster/Passat Trans.

[a914622]

Chirs my mistake. I had an air leak on the vain in the intake. I was thinking if yours was sticking or leaking air that might be the shuttering problem. The vacuum valve it hooks up to had a crack on mine so it wasn't fully opening or closing the "air splitter" in the intake.
The trans pulse should be rock solid. The trans had one or did you have to put it in? Some of the ty756 trans didn't come with it and the have no gear inside. If you have a wrx tran it's probably a ty755?

[motoTrooper]

Quick question -could you give me some dimensions of the engine/trans assembly?

Assembly length, engine width, distance from front of engine to trans axle stubs would be greatly appreciated!

[motoTrooper]

Just found these for comparison sake, the 914 has a 6" longer wheelbase but they seem pretty close...

Well the entire thing from front pulley to end of the shift rod is just under 51"
It is just under 33" wide
And from the stub axle center to the front pulley you have 29" approximately.

All the numbers are approximates but they will get you close enough with a little bit of tape work or a couple card board boxes you can figure out if it will fit
