The 914 conversion, 3.3 Ltr suby upgrade Options

[Chris H.]

The only sensor in that black piece is the MAF sensor which attaches to the end. The challenge with the EG33 is it's one of the few intake manifolds that has two air entry points rather than one like damn near every other car. The Rocky Mountain West intake is pretty good but still may not be enough clearance for you. Someone here might be able to fabricate you one. You really just need the rectangular piece.

RMW Intake:



And if someone raises his/her hand to make one they could probably sell a few more.

(IMG:style_emoticons/default/agree.gif) not hard to make but why (IMG:style_emoticons/default/confused24.gif) labor and materials would get in over the cost most here would want to pay. for what looks like a simple box, And show of hands how many 3.3 EG swaps are on here, the pool seems rather shallow to me.

the Evil one is uncommitted right now, well he is but it is a bus who would want to do one of them, Oh yeah me, but it is on the long list of cars, not the short list. WRX STI AWD Ghia is on the short list. (IMG:style_emoticons/default/aktion035.gif)
Myself which might never get done (IMG:style_emoticons/default/headbang.gif)

I had the same thought about the Subaru swap items: Transhangers and engine mounts are the widest market, but what a few a month if that? Then shifter but zero decibel makes a great setup. Subaru gears has the spools, flanges, rear covers covered, and now a LSD also.

I know there is a Walmart market compared to Subaru gears, Zero decibel, but I just can't bring myself to build crap, let alone sell items I would consider crap that would have my companies name on them.

I would say that maybe there is a market if I would build the engine support, trans support, and make a bolt in package all the way to the drive shafts and cooling, with a plug in harness, and exhaust. Just seems like a lot of work just to see a bunch of parts sit on the shelves.

I am guessing that is why Mark runs so many group buys, as it covers most of the cost of the inthrall run, everything else becomes gravy as it sits and waits for the right 914 person to come around. lower the market potential to just Subaru conversions and things get a bit tighter. And the converters I know in this area just build all their own stuff.

Has anyone ever made a homemade Intake system successfully

My crude drawing would show 180 deg. silicone tubes from throttle body then in to a cylinder with appropriate vacuume attachments ,and then a cone filter on the end... (IMG:style_emoticons/default/confused24.gif) (IMG:style_emoticons/default/confused24.gif)

I like that approach if it fits under the lids of everything. I've seen custom intakes made but none seem to work with the efficiency of the stock intake. It's designed that way with the iris valve to work at lower rpms to eliminate flat spots due to the characteristics of the flat plane crank design. I'm keeping the manifold and the stock setup but adding the upgrades that others have done to make good power with stock reliability since that's the original intent of my build. I like what you've been doing so far and really want to see yours run! (IMG:style_emoticons/default/biggrin.gif)

(IMG:style_emoticons/default/agree.gif) 914's are a small market, conversions even smaller. To do well, you need to be able to make a profit on parts and labor.
Our shop doesn't work on any 914's. The 914 guys don't want to spend big money like the 911 guys (me included). It cost the same to chase parts, wrench, metal work and paint a 914 as a 911 but the 911 guys that we cater to don't blink at a $150-200K quote.

I am very glad our 914 suppliers have made the commitment to support our cars but I know it's not easy to do.

[Chris H.]

Wow you guys really read a lot into that (IMG:style_emoticons/default/biggrin.gif) ....I wasn't suggesting there's a huge market for that piece that a business model could be built around. I just said if someone WANTED to make ONE, they might sell A FEW MORE. I wanted one myself and tried to buy the RMW setup when I flipped the manifold but they were out of stock. Now it's not on the site at all so I guess it's NLA.

[914forme]

(IMG:style_emoticons/default/laugh.gif) Yeah I don't even have the throttle bodies anymore so I would not be able to build a set anyway (IMG:style_emoticons/default/poke.gif)

I never like the dual throttle body anyway Can't even remember what it is for as the IRIS section is not feed by a single side of the TB. Maybe it was the only way to get the volume of air required for the engine with the slopped hood of the SVX. If it was me and I was keeping the stock intake I would build an adapter with a 90 or more degree turn and install a similarly sized single Throttle body off lets say a Ford Mustang, and go one with an easier installation of intake tubing.

Then I would also change out the injectors, MAF, and run a chip in the stock ECU, if I was inclined to go that route.

But I am out not that one also as I am not sure where my intake got to, I had two of them at one point in time. (IMG:style_emoticons/default/av-943.gif)

As a marketing venture it would fail, (IMG:style_emoticons/default/poke.gif)

Thanks MGP4591, Me to LOL Iam trying to keep the EG33 system intact but keeping that 901 trans is a little bit of a set back when it come to the air intake system,.because I want my axle's to line up,( I know I have some wiggle rm with the axle's but not much)..I may end up cutting the bulkhead just enough for the original duct to work,or splice that area with a silicone tube that can be compressed which then cuts air flow so not sure yet but, I checked RMW,..site I don't think they offer the EG33 intake anymore they don't advertise it,..So I will be calling on Monday...I'am sure If I have all the vacuume points connected with the correct air volume a rigged system could work.,even if I get the duct to fit and work on that side it blocks my dip stick,so I may also flip it like chrisH did,..and said I should...after all his is running !!

[flmont]

It would be nice to have that metal box they have or fabed maybe they will tell me who the vendor was/is,.I could block the side portal and attach to the top and then run it strait back that would work I think..

[914forme]

The metal box is the easy part, it is knowing the final design that makes it hard.

You could do this all in tube.

Two tubes that match to TB, and then one capped on one end, and then running over to where your MAF connects Preferably the same size as your final MAF bore. A Good muffler shop could build it. Then add a couple of bungs for the connections you need to support.

You really don't need a large volume of air after the MAF, you just need it not to be restricted.

That would be the simplest way to achieve your goal, a decent fabricator could do it. Heck you could do it with a bit of time, some spot welds, then take it to a welder and have it welded up. Worse case you might have to JBweld the joint to get it air tight.

You could also build this out of copper or other metal, and solder or braze the joints. In this case both wold produce a sealed joint, and it is not a structural part.

Or you could go hog wild, build the tubes flare the ends to make velocity stacks on them, install them into a box, run a tube out the other side, etc.......

K.I.S. KEEP IT SIMPLE!

[mgp4591]

How much clearance do you have between the intake and the engine cover? If you've got the room, keep your little black box and make the changes to run a large intake tube over the top to a better location for your MAF... Make the tube big enough to flow the air 180 degrees vs the 90 that it previously made and I think that would work. If space is tight, maybe look into an ovalized pipe to give you extra clearance.

[flmont]

with No rain tray at this point seems like plenty of room, Never thought about the Oval tubing..Thats a good Idea to ck out...Thanks

[flmont]

Well RMW, had good news and bad news the good, I was told they are going to run a batch of boxes. the bad not for another month and has no price as of today.. (IMG:style_emoticons/default/idea.gif) (IMG:style_emoticons/default/idea.gif)

So I will have one made JIC they change their minds

Why do 180 degrees? It looks like a 90 degree turn straight up could go to a rectangular box plenum/air filter. You could choose a size to match the rectangular filter of your choice. I would slant the bottom of the box to a drain corner and run the verticals beyond the bottom to prevent rain-induced hydro locking.

[914forme]

Warren, he has to have a MAF in line with the intake. So a small box, then a MaF then a filter of some kind.

You could combine all of these into one set of boxes, and drop down to a 90 degrees to the intake.

If I was looking for the fast way out, I would get 2 180 bends in silicone. Drop a radiator return hose spring in each one just to keep it from collapsing, and take the stock box and put it up top. Something like this not sure if the diameter is correct so you would have to measure that.

That is about as simple and inexpensive as it gets, until you feel like building the skills to fab the part, or having some one fab the part for you.

Just looked on EvilBay for SVX Motor or intake, (IMG:style_emoticons/default/WTF.gif) prices on that stuff has sky rocketed. 300% for the engine alone (IMG:style_emoticons/default/confused24.gif)

Why was I looking, I don't need more of them. I was hoping to grab an intake with the TBs to see what I could make. Hell maybe I should just buy another SVX, if it had a 5 or 6 speed manual I would do it in a heart beat . (IMG:style_emoticons/default/wub.gif)

[flmont]

That's exactly what I intend to do for now at least I can get it started and hopefully it will idle,this engine has never been started so I hope it checks out..Thanks for the Info !!

[flmont]

And yea SVX stuff is getting pricey

I saw one on Craigslist not too far from me for $800. 120k miles and a blown reverse gear. Still drove. I almost went for it but I don’t need another car in the driveway.

Might be most of what you need to complete your engine.

[914forme]

Yeah, I am not planning on using one, just figured it would give me something to practice my TIG welding on. LOL. And help a guy out, somebody else needs to get an EG swap done. (IMG:style_emoticons/default/poke.gif) Yes THAT (IMG:style_emoticons/default/poke.gif) is for me.

[flmont]

If it was'nt for the oil pan this would be set correctly
