My 3.3L Subie Conversion Thread, Got me some 914rubber stuff Options

[flmont]

Great video Chris,...could U remember the MPH as U go thru the gears,..and yea,.man sounds great too,...!!!

[914forme]

Sounds great (IMG:style_emoticons/default/piratenanner.gif) BTW wasn't that Bob's complaint about his EG, he would forget it was running at idle. Nice to see it go, all that hard work paid off, and glad to see you got the intake flip worked out.

[mgp4591]

So when you get your new MAF, have you given thought to the Z32 unit from Nissan? It's a larger diameter piece for more airflow and it's supposed to be fairly easy to wire up even though you may be tired of conversion projects by now...
Also, do you think the torque increase is from the added intake runner length? It makes sense that it would but I thought the whole object of this exercise was the fitment issues without cutting into the trunk space.
Great job and thanks for the video - I think that's going to be a project for me also when the time comes. Thanks for the inspiration and the intensive documentation!

Congratulations! You guys are making think I need to pull the 2.5L 4 cylinder out and replace it with a six! (IMG:style_emoticons/default/headbang.gif)

(IMG:style_emoticons/default/piratenanner.gif) (IMG:style_emoticons/default/piratenanner.gif) (IMG:style_emoticons/default/piratenanner.gif) Super fantastic results and you deserve it. (IMG:style_emoticons/default/beerchug.gif) I'm proud of you for sticking with it. None of us talk about it but when things go awry, as the often do, it is disheartening at best. Not to mention the effect it has upon your attitude. Ya did good Bud. I'm glad that you finally can "feel the power". (IMG:style_emoticons/default/sheeplove.gif) awesome, isn't it? It's as if the car thanks you for the transplant and repays you with the feel of force and a six cylinder symphony. Your probably going to find any excuse you can in order to drive it for the next several months. And you will, so have you updated your insurance to reflect your cars value? Did you take your wife and daughter for a ride yet? My wife starts screaming and punching me whenever I floor it. (IMG:style_emoticons/default/happy11.gif) What video recorder did you use? It picks up the sound very well. At what point did you realize that this wasn't "Your Father's 914" and would need some time to learn how to harness the new found power.
Again, congratulations. I'm happy for you. (IMG:style_emoticons/default/beerchug.gif) kent

That 2.5 is nothing to sneeze at. Besides, we all have the same Speed Limit signs to deal with. (IMG:style_emoticons/default/beerchug.gif)

That's funny. My sister lives in France, thirty years of tiny Fiats and other tin econo boxes. When she was over visiting for a summer I gave her a ride, top off, cute little red car, same size as what she's used to. As soon as we were out of the neighborhood I hit it hard and she stuck her arms and legs straight out, bracing for whatever was exploding and about to hit. Straight out, rigid, terror. I laughed like a fool, got her just like when we were kids. Later I let her take her husband out and she did the same thing to him.

My granddaughter used to laugh like crazy, too, but now that she's bigger and more responsible, she says "Grandpa, too fast!!"

Thanks everyone for all the support. Really appreciate it. Thanks for all the parts Bob and Steve! The flip was very successful and I got several small issues resolved I didn't know I had! The oil leak is fixed too. Funny thing is that one of the main problems is still there (idle issue) but since I pretty much changed everything else out or tested it I am nearly 100% sure it's the MAF (which rolled off the trunk...). No one was home when I took it out but I'm sure they will all want rides. Works for me!

The MAF is a known issue with the SVX. They get old and are extremely sensitive to vibration. Some people re-solder them (might try that). You can use a Legacy MAF from the same era. $35 vs $150. I don't know how a Nissan Z32 MAF would react with stock injectors. Anyone have an opinion on that? I know there would be no performance improvement. Just need a different connector to use that I would assume.

The performance improvement is just due to the fact that I replaced the sensor (s) and fixed the MAF wiring. The old intake was actually much longer. Now you can be going 20 in 3rd and step on it and it picks right up. Bob liked the fact that you could literally drive the Subaru 6s around in 5th gear all the time if you wanted. And yes he sometimes couldn't hear his at idle and he did my exhaust. I painted it with ceramic paint. Will post pics right after this.

Frank, I don't know the speeds but I shifted around 5k RPM. Can't really get past 2nd that way in town. Then on to 3rd if you want to keep the revs up...

Ray, if you knew how many times I said "if this doesn't go well I'll buy a late model 2.5 and BE DONE WITH IT" you'd feel great about your engine. I like the EG33 a lot but my next motor will probably be a 4. Maybe the BRZ when it gets cheaper or an EJ25.

Thanks very much for posting the test drive video! (IMG:style_emoticons/default/smilie_pokal.gif)
It is really inspiring to see them and helps keep me motivated to work on my project.

Thanks again for sharing the progress of your build.

[A&P Mech]

Hey Chris, it looks like you are running SpeedHut gauges. How big of a job was it to install them? It looks like your running the GPS speedometer. Can you give me some feedback. I am getting ready to order a set.

Hey you bought your stuff from the right guy. Bob is very knowledgeable. I'm pretty familiar with the parts you bought. Good stuff. Did you buy the R motor or the D motor?

Hey Ray, the Speedhut gauges are very easy to install.

The few very minor challenges are:

- The gauges are just slightly smaller than the openings for the stock 914 cluster. You can wrap them a but with tape and then use the rubber rings, or add a little filler inner ring piece, or make your own face plate. They are BARELY smaller. And you need the 4 1/2 tach and 4" speedo and quad. They measure the faces, not the barrels like VDO.

- The senders for the quad gauge for water temp and oil pressure are 1/8 NTP. Not the same as Subaru at all. For oil pressure I found a nice adapter. Let me look it up and post it here later tonight. For water temp I just got an aluminum 1.25 hose adapter with a 1/8 NPT in it that is made for water temp.

- The oil pressure and water temp wires are too short because they are made for a car with the engine up front so you have to extend them. You COULD put the water temp up front but it really should be very close to the engine. You CANNOT replace your Subaru temp sensor with it. That one has to stay where it is.

The GPS speedo is so easy it's ridiculous. Power it, plug the antenna in. You could also get one that hooks to your trans VSS but I like the GPS better.

(IMG:style_emoticons/default/agree.gif) review would be nicesee we must have pushed the post button at close to the same time. In reality I am sure your typing faster than me, I am two key fingers down. Still thinking I am going to roll my own, but as the car gets closer and closer (IMG:style_emoticons/default/screwy.gif) (I live in my own reality)I think Speed Huts would be a great solution. E-mailed them today and asked if they could put a boast gauge into the speedo or quad gauge. (IMG:style_emoticons/default/happy11.gif)

On the MAF to read the Z MAF you need a ROM Flash, if you can find a stage 2 tune chi,p I say go for it, but you also need bigger injectors. I see a slippery slope ahead sign there to your right.

Grab a 35 dollar MAF, or let me see if I still have mine, and I will ship it up. I sure as hell don't plan on using it.

Awesome job man!

Bob has a "30D" for sale?

[Chris H.]

Thanks Doug! Nice to see you!

You can look at my gauges at Garold's and see what you think Steve. I might try soldering my MAF but if you have one that's awesome.

Kent I think Bob just had an EZ30R left come to think of it. That one was fairly low mileage too. Now the aftermarket systems have finally caught up with the OEM technology so you can run the variable valve timing and stuff.

Got my response back from Speed Hut, they can not or will not do it. Bummer

Aw, c'mon Chris... Looking at posts on the SVX says that the Z32 plus 370 injectors with an chipped ECU will give you over 300 hp. Wouldn't you like that??
On the other hand if I were you, I'd probably be satisfied (for awhile!) with your current upgrades and just wanna drive the damn thing!
And was your previous setup functioning so poorly that you weren't getting all of the engine to the ground? I never saw that in your posts so now you have me wondering... (IMG:style_emoticons/default/idea.gif)

Who does the upgrade on the eg33 to get to 300hp? I remember seeing a website at one time but didn't save the info. Thanks.

[flmont]

mepstein,... it may be Subiechips LLc,.. he said a couple months back he no longer builds SVX motors,.but his website offers those upgrades,But he has no phone number listed ,..So Iam not sure how safe it is to order from that site,..?? plus when I asked about HP and Torque numbers he said he didn't have that info,..??,..But delta cams ,will do cams for SVX engines....

Yeah we'll see. It's plenty fast for me really. The MAF sensor plug was not grounded and I had a bad crank angle sensor so the timing was way off before. Suddenly had a lot of backfiring and loss of power after I hooked up the VSS. Maybe a coincidence but the VSS does provide input that can affect the performance. That's why the power was way down. Initially it was good so the sensor must have gone bad gradually.

Mark, here is some info on the upgrade to Nissan MAF/Injectors/rechip

Subiechips Site

On the Subaru-SVX site the guy who makes these offers group buys (same guy). It's $13 off for every person who orders one, up to a certain number. They can be the standard rechip that just remaps the ECU or the modified one. So if we had say, 5 people buy one the price for each would go down $65 per.
