Single Pass DIY
 
K, not quite DIY. My dad did the most of the work. But metal fab is his specialty.
Before I begin I'd like to say this is meant to be an informational thread. Comments and constructive ideas are welcome, this is my first attempt. However don't come in here and spam my thread with how I fail and blah blah blah unless you actually have successfully built a better single pass and are willing to post pictures and reasons why your mani is superior and are willing to share actual info like this forum is meant to do. Which pretty much eliminates 99.99% of ppl on here.

So firstly I marked how I wanted the pipes to come out.

Then I ground out where I wanted to weld the pipes in.

Then welded the pipes on. They still need to be cut to length but I'm going to wait till I size it up in my car to decide where I'll chop em.

Then we took a stock endplate and built up the one area where we felt there wasn't sufficient enough material to mill out a passage large enough for fluid to pass though.

The most important resource in this process, my father Journeyman Welder, Journeyman Machinist and Journeyman HD Mechanic extraordinaire milling out the passages.

We milled out as much as possible and then finished it off with the die grinder.

I will not have any info on how well this works up for a while as it is winter here and my car is in storage till spring so you'll have to wait till then for that info.

looks awesome, ive been working on this for a while, just getting sum1 to do the machine work has been a pain, gotta get sum1 I can trust. about how much was your total cost on doing this?

l8r,
PD

ls1fbody Dec 28, 2009 09:29 PM

Looks awesome. Kudo's for having the balls to try this out.

I know Qwikredline has a single pass setup, he may venture in here to comment.

Ur dip stick is going hate that bottom tube...I had the same idea a while back, but was going to just drill and tap 2 fittings in...decided not too

TurboTechRacing Dec 28, 2009 09:31 PM

Nice work! Great pictures.

qwikredline Dec 28, 2009 09:39 PM

awesome work on the right track for sure.

Flatgod Dec 28, 2009 09:47 PM

Had to buy a mani but since my dad and I did the work the labour cost was $0.

ya we make them for 600 exchange but its not worth the aggravation, and like you said the 99% wack jobs make it not worth talking about.
you cant pay your dad enough for the craftsmanship he put in.

The dipstick is no problem, just bend it out of the engine if you bend it in the easy way you risk cracking it at the block end. I had a few dipsticks get away from me until i got it right. And a TVS makes a little harder. It can still bolt to the IM needs a spacer stud. You also MUST cover and insulate the power lead from the alternator to the starter motor the single pass makes that a problematical routing

all other advice is off line :lol:

Jrhdpaintball Dec 28, 2009 11:08 PM

i had to move the oil dipstick on mine. also agree with qwikredline for the cover on the alt. with the re route of the dipstick, it comes extremly close to the power wire of the alt.

besides all that, you will need some 90* angles to get it to come out then clear the radiator. pain in the ass at first but im sure ull figure it out.

good luck! looks good

ya i used moulded hose and y 's except for 1 all gently sloping down...iat's say it works...

Flatgod Dec 28, 2009 11:21 PM

I'm going to find hoses with nice 90* bends in them. I hate those plastic 90* elbows and want to use as few connections as possible. Thx Qwik for the info on the alt wire.

mrbelvedere Dec 28, 2009 11:36 PM

sweet work and all thanks for the info

Iats stay pretty good, stock pully tvs, single pass, meth, big cx racing HE... love it lol

i accually used my dual pass endplate, modified slightly.

when i took off the old stock hoses off the stock endplate, save those. they work perfect to get the hoses routed good. you will just need a coupler to extend the rest of the hose. but the hardest part will be done at that pointl.

Flatgod Dec 28, 2009 11:53 PM

I had dual pass on my car before so I pretty much butchered all the stock hoses already. I'm running a TVS, meth, optb with dual FMIC (zzp s3 & big cxr). Had a 2.9 on before but switching to 2.8 after this. Killer chiller unit should arrive this week so it will get that as well. Also looking into the phenolic spacer. I just want to be able to run the 2.8 without issue and be done with heatsoak.

*boostinss* Dec 28, 2009 11:58 PM

OMG! how do you fit both of those heat exchangers in there lol.

ya gonna need a LWB Redline to fit all this stuff....

SCcobaltSS Dec 29, 2009 09:46 AM

That is some nice work OP. I plan on doing this on my upcoming build.

JapEatr Dec 29, 2009 09:59 AM

details on your FMHE setup...

excellent work on the single pass as well

Jazer Dec 29, 2009 10:21 AM

Sub'd - to see pics after work =]

selfinfliction Dec 29, 2009 10:35 AM

good stuff man... :cssNET:

i think the dual exchangers is a waste on a regular system, but your single pass system may actually benefit from it.

instead of adding more exchangers, you should look into getting your biggest exchanger coated in TLTD, it's fairly cheap and can increase cooling efficiency up to 30%

BeermanSSSC Dec 29, 2009 10:55 AM

doesn't he have the ZZP S3? Which is pretty much the biggest.

Flatgod Dec 29, 2009 11:06 AM

The stock H/E is removed and the AC condenser is moved back into the H/E's place. That allows room for the CXR he to be mounted behind the hood latch assembly rather then under it and on the ground, Flashbrandon made a how to for this. Then I mounted the ZZP S3 directly in front of that and hooked them up in sequence. On my old dual pass setup the addition of the ZZP H/E was huge for dropping AIT's.
