Starting my turbo

cruisedeisel · 03-01-09, 08:32 AM

well this is my manifold, what do you think guys. heavy duty? 2x2 1/4 wall square tube with a half inch plate. i got this turbo from an old mercedez 5 cyl 3.0L. pretty close match to my engine. anybody use one before? just waiting for some plumbing parts to hook it all up. will keep updating.

cruisedeisel · 03-01-09, 08:36 AM

air research turbo, i heard they're like a t3 but???

MrMoMo · 03-01-09, 09:37 AM

Cool - did you weld the wastegate closed???

baxter650 · 03-01-09, 11:28 AM

I like it, nice and simple layout with good direct flow.
You going to have it coated?

cruisedeisel · 03-01-09, 06:19 PM

i'll have it coated with the cheapest high temperature paint i can find. go big or go home. go cheap or get a job.

cruisedeisel · 03-01-09, 06:45 PM

got it freshly shaven. it warped out on me a 1/16th when i was welding it. 80 bucks straight up from a machine shop.

eleblanc · 03-01-09, 07:31 PM

The manifold plate seems to have bent due to heat, maybe you should have it machined.

ozwallaby · 03-02-09, 02:03 AM

Can you take a shot down the tubes or is it a bit scarey down there....

cruisedeisel · 03-02-09, 08:08 AM

and the tunnel. they're pretty skoocum. have to get sum kind of wheel on a drill or??? to clean up sum of the slag

cruisedeisel · 03-02-09, 08:13 AM

yes i did, the bolts holding the plate all snapped, yes i coulda got the heat out and all but that woulda taken 5 minutes

cruisedeisel · 03-08-09, 12:56 PM

buil;t them for $50, beats the 300 they wanted from toyota. i warn you this might make your truck shake a little more.

greencruiser · 03-09-09, 02:04 AM

looks kind of scabby

I can beleve they are less costly then Toyotas but do they last as long?
Guess you will be finding some cracks sooner or later, probably sooner....

Would inspect the edges of the welds on a weekly basis to start with......

cruisedeisel · 03-09-09, 10:32 AM

SCABBY?? take a close look at your truck

ozwallaby · 03-10-09, 07:17 AM

mmmm tractorfab.... if it does the job, it's all good.. tho I think your engine mounts may be shortlived ...

eleblanc · 03-10-09, 08:37 AM

Yep i don't think the support will last, how come you don't have the mount brackets on the engine? and tight that crank case cover.

Tapage · 03-10-09, 04:49 PM

if was dealing with a gasser engine .. they will funtion .. but the vibration from any diesel will kill 'em .. but that's just my thought ..

FJn00b · 03-10-09, 04:58 PM

you will end up either cracking your block or break the frame or welding with your mount setup. Also, your manifold will expend by some 30% in all directions once you reach 1000 f or so.

I guess you forgot to calculate that expansion formula when you used a 2x2 soft metal.

30% expansion.... sorry you're wrong....

cruisedeisel · 03-12-09, 09:56 AM

i love it, arf arf!! dog on me a little more. YES tractor fab, it is a tractor now isn't it? an 80 TLC (Tractor Land Cruiser) right? and whats up with Mr. smartie pants with his 30% expansion smasion B.S.
does this fool know what he's talking about? maybe just jealous. well the turbo will be on by the end of april at the latest and we'll just see about expansion and welds snapping. I also have a 5 speed that im gonna put in. will keep posted.

cruisedeisel · 03-12-09, 10:04 AM

has anybody used these bushings on a diesel before? if not, shut the hell up.

just wait till he is done with that setup . His turbo is too far from the heat source and he will have still manifold of his moving to every direction.

Big Blue 84BJ60 · 03-12-09, 08:57 PM

30% expansion on soft metal is almost unheard of what the fawck is that guy smokin shit i want some...
tops 10% and thats pushing it red hot cast will expand 1-5% if meatalurgy has tought me any thing( fuk off i suck at spelling my shop teachers told me so hahaha everyones good at something me its not english) and 5% expansion is with shitty cast iron red hot soft is aboot the same 7-8% tops its all iron/steel

To compesate for expansion... if your worried just youse over sized/coarse threads and open the holes (that the bolt will go through) by aboot 10% tops and youse a split washer tho stop the bolt from loosenig up diesel will unsrew a loose bolt in no time with just the vibration from the motor

but 30% is unheard of... cast aluminum expands to tops 10-15%(and thats pushing it) any more and I would love to see it and prove my old shop teacher wrong we did heat test and aluminum moved the most

this guys full of shit carry on man
so far great build lets hear it running

lol although you did have to shave 1/16 off the exhaust manifold thats aboot 30% lol (sarcasim at its best)

Big Blue 84BJ60 · 03-12-09, 09:06 PM

fjn00b were are you getting this info I really wana know?
LOL wats the web site???

i don't even know what the hell this dude is trying to say. any guessers?

cruisedeisel · 03-12-09, 09:45 PM

tractors move logs don't they?

Big Blue 84BJ60 · 03-12-09, 09:52 PM

YEAH BUDDY THATS AWSOME

I wissh i took picks of my bj60 wit 450 board ft of pine in the back LOL i hit 90 km no problem LOL 5th gear was useless but 4th I could still giver

AS for buddys quote i thinks hes sayiny it wont work. But I think hes full of shit unless he can pull some web site out of his ass that supports the HOARSE SHIT HE'S TALKIN

ozwallaby · 03-13-09, 07:38 AM

30% 39% 30% hah...... according to the 30% theory, a manifold that is 12" long would grow to over 15.5" long when heated to exhaust temps... I think not..... now back to reality...

Moulds used for making aluminium castings are about 2% larger than the finished product (including machining tolerances). So if your casting an aluminium part 12 inches long the mould would be about 12.25 inches long. So that's going from a moulten state to a solid room temp state.

I see your exhaust manifold appears to be mild steel box section, so it's expansion/contraction will be less than 2%, I actually don't think you'll have a prob with it, though original cast iron manifolds sometimes even crack... if it does crack, just weld it back up or cut down a panel of the neighbours fence and make a new one.. easy

ps... Cruisedeisel, you really should change your name to tractorfab... keep up the good work..

sweet project jules too funny some of the posts u are recieving. think mr 30 percent has any cool projects to show u up with or just lips flapping in the wind

duckling · 03-14-09, 07:02 PM

Man those engine mounts are awesome. I would like to have you around to do some welding on my frame. Just the same…I would get some rubber in there somewhere. Just the startup alone is gonna put a load of torque on those mounts. I don't think they'll break, I just worry about the engine.
