I decided to build my own manifold instead of using the obx,it seemed like it would be too thin walled.This is what I have so far its slightly offset so my downpipe will still work.Im going to angle the collector towards the head and if my measurements are right it should clock the turbo tighter to the engine than my log did.All the runners are 13 3/4 inches except number 1 its 14 1/2 inches.

Good job so far!

How is this going to clear your firewall, though?

Very nice. What diameter pipe are u using. Were did u get that header flange?

Looking good!!! That should be an improvement over the log style you had.

How is this going to clear your firewall, though?With the persuasian of a sledge hammer.:eyebrows: No it clears my firewall with about 2 inches to spare,but its already been bumped in slightly.The pic makes it look like it way out there but it actually is only 10 1/2 inches to the outside from the head.

Yes it will be interesting. If the header helps a bunch that will definitely be one of my next projects. Got to fix all the damage and get what I have now working like it supposed too first!!

I want to come over and check it out.I should be able to finish it this weekend hopefully,I get to work on it when there is nothing else going on,which isn't very often.Yeah come on by and check it out,I bought my son a 1990 vnt you need to see too,thats whats been taking up most of my time.I had planned on hving this done by now.

Almost exactly what I was working on. This is mine with an HE351. Plane 2 is 10" from the header mounting face and plane 4 is 1" from the header mounting face. With my engine mounted I measured 10" from the header face to the firewall and 9" from the VC lip to the firewall so this should all fit. Obviously I'm not completely done but I just need to lower runners 1 and 4 to meet up with the flange and then equal things out by lengthening the intermediate pipes in runners 2 and 3. The flange is at 55deg to the mounting surface and the header was designed with 1.5" short radius weld els.

Sorry, almost forgot to say yours is looking :thumb:Thanks,yep they're pretty close to the same thing and that is exactly how my turbo is going to be sitting.What car are you using this on?I have my firewall pushed in slightly already so I know it wont hit,the turbo is actually going to be farther away from the firewall than it was before.I had to offset it to the driver's side about 2 inches so my downpipe wasn't so close to the power steering pump.I still havent quite figured out where Im going to put the wastegate yet,I was thinking out the back I still have to do so test fitting.

Mine is going on a Shadow so I don't know how close that is to a Daytona.


I had to offset it to the driver's side about 2 inches so my downpipe wasn't so close to the power steering pump.

I have a feeling I will be doing the same thing. I need to weld on the 4" bend and take a closer look.


I still havent quite figured out where Im going to put the wastegate yet,I was thinking out the back I still have to do so test fitting.

I will be using the internal gate in the Holset so I may still have to do some work to get the canister to clear but it will be very doable.

Overall I think we will be ending up with a very similar product.

How are you doing the collector? (you know me. ;) )Something simular to the one on this page unless you've got a better Idea.http://www.sdsefi.com/techheader.htm

This would be a better collector if possible. http://www.amsperformance.com/store/images/tn_AMS%20SRT4%20T3T4%20Exhuast%20MANIFOLD.JPG

If you were to do a angle cut on each of your four current runners, then do the same cut on some short pieces, you could achieve the same thing. I personally hate the collector on the sdsefi website

03-15-2007, 07:04 AM
I was going to make a collector like the ams,the only problem might be the angle that the turbo needs to sit.What is the problem with the one on the sds site people have been using that style for years without a problem and had some good results.Remember Im not building an f1 car here.

If you were to do a angle cut on each of your four current runners, then do the same cut on some short pieces, you could achieve the same thing.Ive been looking into collector designs and I believe you're right Im going to build a simular one to the ams except the turbo needs to be angled towards the head.

Frank
03-15-2007, 03:56 PM
My only thing is the big change in volume from the runners to the SDSEFI collector. yes it works but is way less efficent for similar amount of work. If you could tweak the volume and shape to be a better transition then the SDSEFI, then you could do that too.

But good deal and nicely done!

Don't forget that our engines are tipped back, so that the plane of the firewall is not parallel to the plane of the flange on the head. The turbo may be closer to the firewall than it appears in the model, if you only measured the one spot from flange to firewall.

That is a great point. I actually hadn't forgot but with the space I had and the flexibilty to change the flange angle I knew I would be OK once I checked it. Here is a new one tilted at 11deg which is where my engine sits. I changed the flange angle from 55deg to 50 deg and it is still within the 10" firewall. Thanks for the heads up though.

SolidWorks header pics look nice! Got any other angles for us? looks liek 1 & 4 need to merge a little closer to the collector?

I started drawing mine in 3D AutoCAD years ago, then said 'F' it and just started making it, LOL

Except when you don't want to do things twice and you want to make the header while your engine is at the machine shop. This way I was able to make a jig and then a plate to mock the turbo placement to make sure everything would clear or to see if I wanted to move something.

Here's an idea as you do the collector that you could try:
http://hometown.aol.com/russjerome/images/coltheader%20002.jpg
I'm not sure if the pic shows how high the pyramid in the middle
goes, tape would show 2.5" after the pipes join, kinda lets the gass's
merge individualy from what I have read without turbulence. Its as
easily done as you would imagine, 4 pie cut triangle welded up in
a pyramid. Weak pic but you get the idea, kinda picture the 4 different
volumes of exhaust meeting in a slow merge/Burns collector.

edit: 2.5" from the base of transition, this side shot gives and idea:

Looks good Kevin. I just started welding mine up this weekend. My collector will be a bit different but besides that almost identical. I did find I had to move the turbo over 1" to the drivers side so the exhaust would clear the PS pump like you said. I also had to change the 90s at the head to clear the starter similar to what you did. Glad to see you got yours done.

Yea, damnit! Kevin won't leave things alone. Our cars were neck and neck on street radials. Haven't tried mine on slicks yet, so I don't know there. I don't know how much more I can squeak out of my old school 8V crap to keep up. At least he will have his going again before mine so I know what I'm up against!! It's all in fun.

Well that sucks that it didnt work out like that:(

LMK what you figured out w/ the trans and when you get the slicks broken in and back to the track.

Ready to see some updated times:thumb:

I was also curious if the new header would allow more boost or timming on pump gas compared to the log(due to less reversion and back pressure) or if your EGT's changed at all

Kevin needs to reply, but I know his EGT's dropped at least 100deg with the same tune. I'm not sure about the timing. I don't think Kevin is sure yet either. We do know that on the dyno, that the engine didn't make any more HP with more advance. But the dyno session wasn't totally accurate with the high stall converter and the way Kevin loaded the engine on it. It will take some track sessions to nail down the ign. advance. Kevin's car is a beast. His engine in my car (lighter) would be scairy fast!! He is really making me sweat and get down to the nitty gritty to make an even a lighter 8V car keep up with him. But I like a friendly challenge. I have a feeling that when he gets his trans finished, a new personal best will surely happen for him! I'm going slowly about putting my car back together until I see what he runs. I have to at least know what I will be up against! :D
