Hey guys. A buddy of ours that lives up in NY and frequently comes down to visit, has a bunch of 1st gens. All of which i have tuned.

But his nice one which is a 90 D250 with a Locker in the rear and a tight 727 auto, he wants to make his toy.

So here's a list of what we've already bought and I'm putting on for him this summer.

Glowshift Gauges
4" Turbo Back Exhaust
AFE Air Filter & I made him an old smokey mount
DennyT fuel pin
HE315cw turbo from an 05 ....no elbow came with it

right now the truck has a rotated fuel pin and a 1/8 timing bump.

So i don't think low 14's or possibly even 13's is out of the question here as it's a light truck and has a Locker in the back so traction shouldn't be too big of an issue.

I've never done a turbo swap before....So If anyone has pictures of their crossover setups with HE351's on NON i/c trucks that'd be great.

Another big thing is Exhaust, the downpipe we got with the DE kit is 4" but has a 3" Flange....Do i need a special size flange for the HE351 then weld it to the 4" downpipe?

If anyone has links to certain parts I will need like the flange for the intake if i decide to make a custom crossover? and the exhaust flange?

Thanks. I know ther'es a bunch of you that have done this swap before.

 

Do some searchin. Turbos are pretty easy to swap. I've seen a pic of one on a non ic with a 90* rubber elbow and custom crossover tube from what it looked like. If you can get a 3rd gen downpipe for cheap then get it and cut the flange off it and weld it on the new downpipe. I didn't use the cast elbow and just v band clamped it and it held and sealed fine.

 

Hey,

I just installed the 4" DE kit and 351CW on my 91. I bought a flange from Jacob at Diesel Auto Power and had it welded on the DP. They cut off the 3" flange and returned it to me.

 

Search much kid?

Oh wow looky who responded on the 2nd post too....

 

I feel like i'm on my chevy truck forum again, jeez.

I get an error every time i try to search that's why i've never been able to on my computer.

But i forgot JustRamit did this swap on his truck so I will probably get him to help. The only turbo swap i've ever done was an HX35 and that was almost bolt on.

 

Hi brandon, long time no talk. Yeah i have pictures and all the adapters with receipts and what not. I might be able to have another flange made, for you, i just need measurements. I just found out about a lathe n sweet cnc machine... and all i have to do is ask, politely.

 

The flange for the intake manifold? I would like to do a 2.5" Pipe going from the intake manifold to the compressor since the compressor outlet is 2.5" I believe.

 

yeah the compressor outlet is a 2.5" ID, 2.75" OD

 

No i was refferring to the flange coming off the turbo, without the elbow(turn down) you need a flange to weld onto a 4" tight radius 90* elbow. 2wd will be easy for welding the exhaust up, its basically a straight shot. I have 1 flange made for an intake horn, its 3/8 steel. I wanted to make a few of them because its a basic shape and i have a few ideas i want to play around with. Including that oval tubing... Another thing to look into getting is a 90* rubber elbow to exit the housing. I wanted to cut the turn out off in such a way where it could be aimed the correct way. and welded back together, but idk if this could work.

 

I'm good on the exhaust. His truck has a full 4" Diamond Eye exhaust. I just need to figure a way to attach the turbo to the downpipe so I think i'm gonna buy that flange from diesel Auto or whatever and weld it onto the end of the DP and get the matching band clamp for it as well.
