Well, after months of design and testing... it is what it is. JE designed an intake manifold and modified an Injen CAI to go with it. After some gains with the first design, they thought a smaller plenum and longer runners would yield more power... alas, it lost power so we put the 1st version back on and called it a day. The attached dyno also includes the NST pulley and my (now quieter) 2.5 custom stainless exhaust. As the numbers were a little dissapointing, my guess is that the mani will not go into production. I had planned to have them also do custom long-tube headers and catless dp but (which, in a Lotus they did, produced nearly 15hp)... but my BMW 1M will be here in a couple of weeks and I will be spending my doe modding it instead. I'm keeping the xD (I love our little car), but as this will now be my wife's car and she couldn't care less about getting more power if it = louder, power wise, I'm done. However, my brakes are shot so I just ordered some Rotora rotors and Hawk ceramic pads.

Here's a better look at the modified Injen CAI that tucks nicely behind the bumper. A pic of the 2nd version of the mani that lost power but you can see the type of work JE can do, really great people. The exhaust, and... my new baby which I should have later this month.

Oh, forgot the dyno sheet...

You know I think I still want one. I mean it looks like it looses power above 4.9k rpm, but gains pretty good tq around 7 ftlbs at 3200. So there are gains below 5k rpm, where my daily driving maintains. Who should I talk to?
Oh, and congrats on the new car. Those are sweet!

Yeah, I was a little disappointed but, I guess a little down low is better than nothing. Maybe this is why no one has made a mani for our xD, not an easy task. You should talk to James if you're interested, he's the owner. And thanks, really excited about the baby-M - already got a full sponsorship from CP-E and if I take delivery on schedule, we're hoping to have the first modded 1M and hopefully that'll mean some more sponsors before press... we'll see... I'm sure plenty of other guys have the same idea.:nails:

If James does not intend to make any more, would you be willing to sell yours? (doesn't hurt to ask) Also why did they go with a smaller plenum for the longer runners?

Mmmm, I'll think on it... I paid a boat-load for it...I'm almost embarrassed to say how much.

James says that NA cars typically do better with a smaller plenum but longer runners (bigger plenum for turbo cars). With our car there's not much room to play with runners so the 2nd version used longer but folded runners. But, for whatever reason, it lost power so it was scrapped. After flogging it while doing some errands today, one thing I noticed is that the new mani was really hot, maybe that's normal but I just checked it an hour later, still really hot... wonder if heat is an issue. I don't know, I only know what I read in car mags and forums... and only understand about half of that!

Thank you for the insight. Is your car an auto by any chance?

Yup

Look at it like this, at least this shows that the OE Toyota unit is a fairly good design.

LOL, guess you're right.

sorry to hear that dude. but atlas you have a nice beamer coming 8) . But thats without a tune right? if you ever consider selling it. Let me know. Maybe we can work something out. I will try to continue modding this little box and still give the 2zr some hope :icon_biggrin:

True dat! And all though I probably won't mod my xD much more, I do love it and will keep checking in now and then. (I'm "Ohcrap" on 1-Addicts too !)

haha cool beans! and thanks again :cool:

Well, I've been communicating with James Evans from JE, and here's what he said.

Hello, I took a look at the thread and figured I would let you guys know that your comparing the wrong runs. The run showing the high top end gain is the new manifold. Which is why this manifold would be well suited for turbo. The lower more rounded dyno plot was the stock manifold. The gains were all on the top end with this setup. It would be nice to test one more design change that we have, but I would want to try this on a manual trans and not the auto. I think this AT setup is skewing the number a little. I think it could be mass produced for under $1000, but we would have to make ten or more to make it that cheap. We, "JE" do a lot of R&D and testing for a company called "Sikky", these guys would be the ones mass producing these manifolds should they decide to. I think they would probably want to test this final design change first before doing so and it would need to be on an automatic. We would have to find someone local to maryland willing to buy this manifold and offer up there car for a before and after dyno comparison. If this goes well, it could go into production but based on the gains this current manifold would really be sold and marketed as a turbo manifold. That is very interesting that the manifold is listed as the same part as those other cars. I had no idea. If it could be sold to them as well it might convince the powers that be at Sikky to invest some more time and money into it. Steve was kind enough to put up some money initially to build this manifold, but our combined design time and CNC time is ten times what steve has in it. Which is why we are at a crossroads if we want to try one more time, who knows....as they say, third times a charm?

I want one, but it looks like we need another good soul to step forward from Maryland. If this product could be marketed to other vehicles with the same manifold I'm sure we could secure 10+ people(1.8 Corolla, Matrix, XD, Pontiac Vibe). So is any one game?

Mines a manual ... and your saying we need to give more $$$ to find out if we can get more ponies out og this intake? I can hit up the corolla ppl and see if anyone is interested. and didn't they have crap's xd for months before they handed it back to them .. btw how much more we tlkn about

Did they ever show a pic of dynateks intake design? Maybe je can kinda get the idea nd copy it lol

They shud make us cams nd pistons nd I'm deff. Down lol

im in a 5spd, and even though im in northern VA ill make a drive if they are really in need. only thing is this is my DD so i cant hand my car over for days lol. :icon_juggle: but anything that could potentially give the xD more parts and powuh is fine by me.

I'm. Jst about 45 mins away but yea they looking for an auto. So how much power they make again? I man thats without injectors and tune

In the follow up e-mail, I asked if he wanted a auto or a manual, and he said a manual would be preferable. I think he was referring to an auto for continuity sake.

Just to be clear...JE Import Performance is a great shop, with super friendly people, that do some truly incredible work. You should see some of the insanely awesome cars they've built. The work they do is top notch and they are completely candid and fair.

Just wanted to make sure that's clear. I would trust them with any of my cars.

i feel like no one is listening to me :nope: lol

anywho ii sent a post on my corolla friends and see if theres any interest.

Xdkidd, don't you want to drop your car off?

not enough funds yet...

Ohcrap, how long and how much was it for one manifold?

Ohcrap, how long and how much was it for one manifold?

Expect to have your car in the shop for a fews days at a time, a few times. But James, Anthony, etc, are really good about scheduling and coordinating so that your down time is minimized. And no matter what, you'll likely come away with at least some positive results, not to mention, something custom, beautiful, and one-of-a-kind.

Cost, well as James said, they will be eating a lot more than you in R&D, CNC, dyno testing, etc, but you'd have to get with James for a quote.

what about test nd mid pipes... im sure a lot of ppl be interested in that

what about test nd mid pipes... im sure a lot of ppl be interested in that

I agree, LT headers and catless mid would definitely be great bang for the buck after production... just need someone to pony up for the initial development set. I did my turn, somebody else's turn to step up!

I am conflicted in posting this, but it would save me some money. Mr. Evans e-mailed me again, and had more info for me. The reason I'm conflicted is because I halfway wanted to keep it to myself, and drive up there (~1000 mile trip, 1 way) to be the first to get this. After doing some calculations; gas would be ~$200 round trip + hotel and I would need to wait to schedule time off work. If someone beats me to it well that would be fine as well. Here's what he had to say.

Oh, yeah I had a typo in that response. I meant to say manual when I wrote auto. The manual would be ideal for more accurate numbers, the auto would not necessarily be needed to test again because we will be able to measure the gains from the auto compared to the newer design on the manual. As for the manifold, I would be willing to cap it at $1000 installed for the third version if someone was willing to pony up the cash. This would include before and after dyno testing and downtime would be two days. This person would need to call us and schedule an appointment whenever they are ready. On a side note, anytime someone sees some demand for parts on anything we are always willing to look into it and see if it's something that could be developed and mass produced here in the USA. We enjoy working with Sikky manufacturing because they have the ability to take our working and tested prototypes and put them into production. The beauty of Sikky Manufacturing, is everything they make is 100% made in the USA and top notch materials. Not like almost all the parts made and sold today, that come out of China using really crappy materials. For example, if there is demand for a quality header and or test pipe setup on these cars and some kind of group buy can be organized to get the quantities up to a point that makes sense we would be all for developing this or anything else. The bottom line when looking at performance parts for this engine is that it was designed from the ground up as an economy engine. Gains can be had from performance parts, but because of the engine design the gains won't be record breaking. Although a 5 hp gain does not sound like a lot, on an engine like the one in the XD with the base line power number it makes it's still a good gain that would be felt in the seat of your pants so to speak. It's all about the percentage.

though i live not too far. I don't have enough funds so u mite beat me to it ... oh wells. its a good offer.

Did anyone ever go to JE for the 3rd intake design?

nah ii lost faith in that but they are gonna get some work done for me over the summer.

I went up to JE import performance, and didn't have great luck. They were professional and very knowledgeable. They had it done in the time they quoted me, and they made a good looking product. This version has short straight runners, no velocity stacks, but they tapered the runners. The fit was almost perfect except it rubs the bar that latches hood down. Since I don't live close, and I had to get back Chattanooga I didn't ask them to modify it any. I felt like they would if I had asked, but time was a factor for me. In the dyno results, the car gained power low, but lost HP and a gob of torque when the vvti kicked in. Then it gained again above 5k rpm. I was surprised at the stock numbers I had because I expected a few more HPs from what I had done previously to my car, but I'll chalk it up to needing to clean the filter and the heat ( it was a high of 101 when I left). I had 10 hours of driving to get familiar with the unit (drive home), and was hoping that the ECU would get use to the changes, but it never did. It's hard to butt dyno, but I defiantly noticed the lack of power where the vvti would kick in. I'm still happy I did it because the journey itself was fun, and well just because I tried. I do think the intake manifold could be updated from stock, but I'll have to wait and hope.

Here you can see how short the runners are compared to stock

Damn u shud of hit me up .. ii wld of met up wif you at je. But glad you still enjoy your product. Its def. A one of a kind piece.. you can turbo now lol

That dyno graph makes me sad. :(

That dyno graph makes me sad. :(

Don't be sad little buddy. It's just a graph.

once the vvti kicked in, it must of been a little depressing. "omg this POWE........awe....."

Yeah it really sucked on the highway trying to pass somebody. I'm in the proses of installing my stock manifold. Do you guys have any pics of the hose routing? Im down to a couple, but not quite sure what goes where. A pic of under the throttle body would be very much appreciated!

you can tune it now. Fuel injected

never mind i figured it out. thanx
