NICE RACK


But seriously, that looks nice. I've been thinking about how 'I could get some spare tires of the floor recently. Gonna have to fire up the welder.

It is just some 1/2" conduit that I squished the ends on, bent to lay flat against the wall, and drilled holes in. The other side is just slightly smushed the ends so it welded to the long, straight piece better.

This is only about $3 worth of material and 30min worth of fab time. The materials are 1/2" conduit, flat black spray paint, some #3 2" SS screws, and a small amount of welding.

^I was wondering the same thing. How are you planning to smoothly accomplish the transition from circle to rectangle with an accurate shape at the port side?

I've been thinking of trying my hand at fabbing an intake mani for awhile. Your pics are really inspiring me to try it... alas, I don't have access to all the tools you are using so I would have to be a bit more creative.

[RipperXX]

Did I tell you, your my new best friend? lol





Very nice work!

[topstreet]

You guys are funny!

The idea with the intake manifold is very simple. All you are doing is using a vice, forming die, splaying machine or something to that nature. Then you squish the end untill you are happy with the shape. In one of the above pics I posted... You can see one of the tubes has already been formed to the rough shape I need for the head port. That was done with a bench vise.

I hope the guys at Road Race engineering (Road///Race Engineering Mitsubishi Eclipse Parts and Performance) dont mind me refferencing a few pics of theres.

This one is of a Magnus street manifold. Notice the flange side is the rectangular shape, but down the runner, near the plenum, is the round.



This one you can see the transision really well from the side.



And of course... A picture from the top to show the transision from the other side.




So basically, I am not trying to do anything out of the ordinary. Just going from what my (and others) experience has proven works.

I wasn't being funny just sarcastic!....

Build your own intake manifold

I would be interested in adding your design ideas to that thread. I'm interested in your plenum volume specifically.

I was saying "you guys are funny" to this one, and the "NICE RACK" comment. Not you... Sorry, should have quoted.

I quickly went through the intake manifold build thread you have, and thats crazy how you and I came up with a lot of the same ideas, completely seperately.

The top of this design is just a 4"x18.125"x.125" wall 6061 extruded aluminum. Then its cut in half. The throttle body side has 3" tall side plates, that tapper to 2"at the end of the plenum. The base plate is 4" wide.

The ITB intake manifold I used to have was basically the same thing but with 2" tall side, going to 1". It had the same "half tube" top piece. This is the manifold I was making 800+ whp with.

BUT!!!..... I was out in the shop last night and I might be scrapping that design. I bent up a plenum a few weeks ago that I didnt like at first. Now that I can see it with the base plate and the runners attached... It looks much better then the current design that I have pictures posted of. I will get a "prototype" picture today.

Jake Hanhardt

[topstreet]

This is the plenum design I was originally working on, before the square one with the round top. I got finished bending this one and disliked it. Now... I am giving it a second look and liking it more. This one is just a prototype. The finished product will have the same design, but stand slightly taller. I am just changing 2 of the bends from 45degs to 30, and one of the bends to a 60deg. This is going to stretch it up a hair.

I would like to know everyones opinions on what they like or dont like about each.

looks good man

keep up the work.

Hi jake. Its been along time. By the way, if didnt tell you before, thank you for all of your help with my last project. Speaking of projects. I am starting another project. Another 2g. I am going to make sure that this project gets the AWD conversion. I am trying to get to same level or alittle furthur. I am hoping to get your assistance again.
I am happy to see that you are getting back into the swing of things. The work that you are doing looks really good. I dont remember if you mentioned it before, but you selling of the items that you making. Or, are they just one off items? If you are selling them, I am interested in seeing using your product. Especially, the twin scroll manifold. I love they way they look. The welds look perfect. And the design looks flawless.The intake manifold is coming along nicely. I would love to do some dyno comparison using my Venom/DNP combo, against jhracing intake and exhaust manifold. If you dont mind, I will post the dyno results.
If you are interested in doing a couple of things for me. I am in doing a dual fuel rails and I need a fuel cell. Can you help me out?

Anyway, Thanks again.

Hey Kene!

I am glad to hear that you are going to be putting another 2G together. Its too bad that your last one got wrecked before it got finished being tuned.

Anyways, Thanks for the input on the products! I have been working like crazy to get the manifolds put together. Its nice to hear that you are liking what you are seeing.

It would be really cool to see some comparison on the dyno for HP. If you need any parts you just have to send me an email and let me know. I like being able to help the DSM community when I can. Expecially with your setup. If fate ever lets you get put together AND finished... Its really going to kick butt! You will get a good chance to see the fuel rails that I am going to be making on my car, and hopefully its something that you like.

Thanks again Kene, and give me a call sometime so we can bs.

Later,

That's a pretty nice looking intake manifold. I really like my JMF RWD manifold. Too bad I can't use it. I don't have enough room with my shock towers to clear it. It also sticks out too far for me to run intercooler piping. If you, or anyone wants pics of this manifold, I can post them here. It's a superior design to the Magnus unit that people complain about. Apparently people running high boost are breaking the welds on the Magnus units. The JMF unit has fewer welds and are much thicker looking welds than the Magnus or other units.

[topstreet]

Thanks for the input imtall77... I REALLY don't want to start comparing manifolds in this thread.

I'm sorry if I gave the wrong idea by posting the few pics of the Magnus one. The ONLY thing I was trying to do there, was to show the "reshaping" of the runner at the head flange. I was not trying to start a discussion about, one reason or another, about why someones is better or worse.

Just out of curiosity though... Why cant you use that one???

Jake Hanhardt

[iamtall77]

The JMF unit is just too big for my car. I ran into clearance issues with it and my brake master cylinder and also intercooler piping. I have a pic on photbucket of the master cylinder clearance. It's about enough to fit a business card. And with an NA throttle body, I have about 1.5" from the TB to the radiator inlet. I'm working on another design that should make life much simpler. I'll reveal my secrets when I get it back from the welder.

I wasn't trying to say who had a better intake manifold. I was just trying to point out the differences in each design, so that you don't make the same mistakes. If you have the time and skill, why not make your own. I think you have things handled. I was just trying to give some perspective on what might work.

[gsx4g64]

Hey Jake,

How are things going? Yeah, it was terrible to see my car wrecked by a supra. But, I am on the path again. I still have my manifolds, but I am interested in using yours. I went by your site, and saw that you have a sale on your exhaust manifold. The price was good before, but it is even better now. I will take one of the T4. Can the wastegate flange be modified to fit two hks 50 wastegates? Besides from the manifold lookinf great, what can I expect from this manifold? I heard that you are offering a lifetime warranty.

Anyway. Let me know what you need from to get the manifold out. Also, when are you expecting the intake manifold to be finished?

[Boost92awd]

Hows the build coming along? Any updates?

[dsm614]

Damn Jake why didnt you tell me you had a RWD build thread?

[Slippi84]

JAKE ANSWER YOUR EMAILS !!! This is one nice build man the rwd talon build has always seemed like a interesting process to me.


Side note..JAKE ANSWER YOUR EMAILS !!! This last t4 manifold buisness better not be true I want one of those things bad for my stroker build. Come on let one more go

[topstreet]

Hey Guys!

Sorry I havent had a minute to step away in the last month here. I have been working like crazy to keep up with manifold orders and havent had a lot of extra time for the car.

BTW Sean.... I got one with your name on it. Call me and we'll get it going.

Alright... Here is the skinny on the project. This weekend I was able to pickup the trans that I am going to be using. I decided to go with the R154 because I like the strength, gearing, that its built by Toyota, and that I had one become available to me.

I started mocking up what would need to be modified to get the trans to fit a 4G63. So that is what the mid plate is doing clamped onto it. Dont pay to much attention to it just yet, its just in the mock up phase.










Next, I was able to get my hands on the links and rod ends I will be using for the 4 LINK!!! This is just getting the axle in location and figuring out what else needs to happen before its ready to roll.

Jake, Billsautofab.com makes the bellhousing adapter you need to use that tranny on a 4G63.

Check it out, thats who made my adapters to use all the chevy parts on my RWD build... very great work.

Thanks for the helpful input. I have seen his bellhousings and they look like that are good stuff. But, The way things are looking right now... I am going to be building up enough weld on the housing to redrill the stock R154 bellhousing to fit the dsm bolt pattern. I know this sounds kinda crazy, but does it sound better or worse than making your own bellhousing like Bill does???

I am not 100% about this but it looks like I can completely fill the upper two bolt holes on the supra trans and drill out the correct pattern (slightly smaller). The left one in the picture looks as if it could be drilled as is, but I will probably reenforce it to be safe. And the one on the right will need to be completely added to the trans. Otherwise I know I have the one that Bill is making to fall back on.

Thanks again for the added info!

Jake Hanhardt

[dsm614]

Haha, I was sure you already had something up your sleeve

Just didn't know if you knew of them or not so I passed the info.

Keep us updated man!

IMO, the biggest pain in the ass with not using the adapter plate is going to be making sure the centerline of the crank and input shaft are dead on. I wouldn't be willing to bother with it. That 4 link gives me wood. I'm sure those are the finaly locations for the bars, that would make for a pretty bizzarre IC. Is the axle at ride height in the pics?

Thanks!

The nice thing about getting the two lined up dead nuts, is that the Supra not only uses a pilot bearing (getting machined into my flywheel) but it has bigger access holes in the bell housing. These are there because stock, these have a "pull release" style clutch instead of a "push to release". So I should be able to do a dry run, and just have the flywheel in there (no clutch) and watch to make sure the pilot engages the bearing without any issues.

I think the reason you see adapter plates for the GM tranys and not the R154, is because the bell housing on the R154 is so close that the bolt holes damn near overlap. So you wouldn't really be able to bolt it from the back of the plate, and then bolt the trans to the plate. The bolt heads would hit.

The 4 link is just about ride height right now. You can see in the one picture (with the wheel on the milk crate) that the axles housing is only slightly lower then the center of the wheel.

Excuse my ignorance... But when you said "bizzarre IC" what is that?

Jake Hanhardt

[topnotchgsx]

Not sure how much you are going to like the r154 Jake. They can hold some power yes, and I like the gear ratio's very much, but if you are wanting to go the toyota route, IMHO you should have just bit the bullet and got the Getrag V160 6-speed. Most people can handle 6-700 horsepower with the r154, and a couple out there have 800+ but those may just be factory freaks and I am not sure how much abuse those transmissions in those cars are actually being put through. On the other hand, there are COUNTLESS v160's out there handling 1000, 1100, 1200, 1400, you name it horsepower. Granted they are freaking EXPENSIVE transmissions, but they are worth it. I went ahead and bit the bullet on my supra and dropped $2200 on a used v160 that needs a new 3rd gear syncro. New they are right under $5000, but you can find them used in great working order in the $3000-$3500 ball park. Its a huge price to bite off, but I think it's well worth it.

BTW, I always follow your stuff and love it. You truly do inspire me, and I will be following the same path you are taking as soon as I get out of school! Keep it up!

[wishihadatalon]

Looks good Jake. Let me know how this all works out, I will probably be contacting you in the future because my buddy just picked up a 76 dodge colt that we are going to 4g63 at some point.

[bastarddsm]

Jake, bills autofab actually makes a whole bellhousing, not an adaptor. He also make the same deal for t56 transmissions.

What are your plans for the front end? Theres kind of a steering rack where your tanny needs to be. Mr. Newton says this is a big no-no. I do know that member morphius had a big block pontiac in 1gawd. He did have some pictures in his gallery.

That's hilarious. I'm sure he's got it sorted, or at least a plan. There are a couple more RWD dsm's running around on this board. 95GSXracer up there comes to mind

Put the knuckles on the opposite side and run the rack in the front hahaha I am sure you would have a few bump steer problems that way, not to mention a whole bunch of other issues.

[bastarddsm]

Most are tube chassied cars. thats easy then. just put a clip on it, I was wondering if that was he was doing. See I wanted to do this, but I didn't want a clip put on as it wouldn't be a street car deal.
