-90 Burb is going to get the C

[ttammeslehto]

Thank you guys again!



Suburban right after test runs and wash. Could you believe, it's Dec and we still don't have a snow, just that damned rain almost every day, gotto say, I just hate winter time.

Changed the oils yesterday for second time. First was right after 20min run to break in the cam and this was the second after 250miles. Changed also Frantz filter for first time. It's dark due to collecting a lot of Tech Line assembly lubricant, which was used on every possible bearing in the engine.

Boy that sits nice.

Congratulations, Timo!

Although seeing this makes me wish I had time to work on my project rig...

Congrats Timo. . !!!



Speaking for myself (& probably a few other folks too), you've been pretty inspirational to the repower "effort". . Amazing craftsmanship, excellent photo documentation, with *perserverance* & *patience* that rivals anyone I know. . Kudos, man. .



Way to go. . !!!!

Thanks Dudes!



Matt, Lets do a swap, if you clean up my garage, I will finish your Jeep! :-laf



Okie then, last mod. to the burban before I need to start digging in to the junk of my garage. Couldn't clean it up before I got the OD switch thing done.

I don’t like to add switches all over the dash, so I needed to tinker something else. Noticed that tilt lever can be moved forward but it doesn't serve any function. What a perfect place to hide OD switch inside the column. OD needs just a ground pulse to work, so the micro switch grounds the OD wire when you push the tilt lever forward. Wire from the switch runs next to the cruise control wires, rest of it, is just simple things like drilling a hole for the tip of the switch etc. the pics are pretty self-explaining.

Haven't yet started to clean up my garage, since I got a brand new OEM GM dash pad and couldn't just keep my hands off to replace the old cracked one. So last evening spent in the garage was well worth it.

I miss your build up progress... . this thread should be put on the first page for everyone to see how a complete conversion should be done... .

There's going to be a little break of my projects. Like said before the garage needs a major clean up and a proper ventilation. I also need to do some work in the house what I have postponed for some time and promised to do them right after the burban. Don't worry, I'll back with a new engine related stuff. Can't just sit on a sofa and watch TV.

Anyway, at this point I like to say big thanks for all the guys at TDR whom has helped me one way or the other.

Biggest compliments are going to the following persons.

Allan McClure, been knowing him years, but never seen in person. Ones we were close, in N. Y. air port we missed each other by 10min... . He has passed a huge amount of parts over me.

Scott Benz, he has been patient enough to answer all of my questions and also helped me with the parts.

Harry Piers, there was a lot of mails going back and forth, thanks for giving an answer for all of my questions. Lets keep in touch.

Paul, thanks for showing us around in New Port and passing some parts. I wish to visit again at some point.

Mark Kendrick, great and helpful person, thanks for the meter deal.

Britannic, thanks for the good deal of parts.

Matt (HoleshotHolset) he has been around on my thread since day one!

Hey Timmo, you're very welcome - your project is an inspiration and focal point for conversions on TDR. I've never seen such attention to detail and excellent engineering in many years. We just opened another NAPA store in Davis, CA, so I must appologise for not writing sooner - it's been really hectic getting the new NAPA store up and going.



Very best regards, britannic AKA Neil, the "Brit" NAPA store owner!

Heck, I was just honored to help out on such a neat project with someone that is as nuts as me about building stuff yourself.



We should do a top 10 for what parts of the project were the most impressive to the readers. I bet the header or the muffler would be in the top 5.



Enjoy the "Burb". I miss mine... .

Thanks, Timo! I've mostly just been here for moral support and to drool all over your fine examples of expert craftmanship.

Just a short update, odometer shows now 1600 miles. Have done one longer road trip and get around 24. 5mpg. When driving 60mph. Not bad at all, even with 370's and thick washers, although going to replace them with thinner ones, soon as I get my garage back in order. Ones done, going to check the valve lash, maybe adjust timing for 16 or so. Slide the plate, raise the boost etc. But I'm going to give easy life for the engine until spring, on winter, more power is pretty much useless.



I tried to collect most of the engine spec for the list below, since now they are dropped all over the thread.



List of engine goodies:

370's

PDR cam

HX-40/16

#10 plate

Bigger delivery valves

Coatings on pistons, cylinders, valves, bearing surfaces, cam, exh. manifold, turbine housing and down pipe

Ported head

Better exhaust manifold

4. 2" exhaust all the way

Copper head gasket.

ARP studs.

Total Seal second rings

[wicked6]

I love it -



"Better exhaust manifold"..... LOL!!!



Damn, Timo - that's gotta be the understatement of the year. . !!!!

[Vaughn MacKenzie]

Timo, thanks for the update. I am curious how well you think the manifold works in terms of spoolup and engine response. I know it may not be easy to tell because of all the mods you did during your buildup though. Have you driven or ridden in Dodge 12-valve trucks?



One thing that would be cool is some video shots of your rig, if you had a way to put some on the 'web and some time to shoot some.

 

[ttammeslehto]

That's pretty much impossible to say how well the manifold works on my truck compared with a truck with stock manifold. Maybe egt numbers will give some directions, on a flat surface during 60MPH with truck alone, egt's are around 350F-400F, have seen 300F too. But then again, I have PDR cam, ported head, matched runners for the head and turbo, 4. 2" exhaust pipe, flow through muffler etc. Friend of mine have a -96 Ram, I had driven that, it builds the boost faster than mine, since it's with stock hx-35 and I have a hx-40/16 but it's slower due to a lot of things, like a 35" tires, 3. 54 rear end and it's heavier than Suburban. I have a 265/75x16 tires, 3. 73 rear end plus all the engine mods. To do a comparison I should have another Suburban with stock Cummins in it, then just swap in my exhaust manifold to see the difference.

Towing a trailer with a Jeep on last Sun. the weight of the trailer wasn't too much for the Burb. you can hardly feel that there's something hitched. Only bad thing while trailering is the stock converter, the stall speed is way too high. But ones you get the lock up on, then it pulls like a dream. The pic was taken before taking off, it was damn cold morning, around 1F. While pulling the trailer the egt's were between 400F to 650F but it's was a cold day and I only got it up to 650 while doing uphill and punching the pedal for just having some acceleration, I just can't keep my foot off the go pedal when it's uphill, boost builds up so nicely, turbo whistles and brings a smile to my face

Lost oil pressure and had a knocking sound. Opened it up to found a spun rod bearing on #6. Most likely it's been running dry on initial start up and damaged a bit and finally let it go after 3000 miles. Pics show spray pattern with 370's, "thin washers" and 13. 9 of timing, also damaged #6 rod bearing and crank. This morning picked up another crank and a rod since it was damaged too badly, luckily there wasn't any contact with the piston and valves. The coatings on the old crank were looking just like they should be with no peeling off anywhere. Looking to get it back together for the weekend to have a few spins around.



Timo

 

[Desperado]

Sorry to hear of your problems but it sounds like you have it all worked out. I lost the head gasket on my rig this last weekend. Either way it is a dummer.

 

[HRDROKN]

Timo,

I've watched you build for some time, you do great work. While you have it down, check the alignment on the cam bearings. On the older 855 cummins, if the cam bearing was turned off center just a bit. The oil hole feeding the main and rod bearing was blocked enough to starve the rod. I've not looked at a 6bt block. They may have cured this problem.



Bluetick.

 

[nickleinonen]

dude, that sucks about the spun bearing. .
