Diy t4 all input welcome
okay guys my buddy has finally decided to upgrade his turbo on his truck he currently has stage 1s and exhaust also this truck is a e99 truck I know I know this is the obs forum but he’s not a member his plan is to in the future to have is injectors upgraded to stage2
but for time being he’s going to just upgrade turbo and put a t500 in while at it he’s planning on ordering a s369sxe and a .91 Exhaust housing the plan is to build a t4 Mount at same time he orders the turbo he’s ordering new stock up pipes to use and some exhaust bellows and vbands for each uppipe and some pre bent exhaust pipe I’ve read multiple diy t4 threads but I thought id see if you guys would give any tips or tricks or any recommendations for us on this project I’ll post pics once stuff starts coming in also I’ve got my old engine on stand with correct drivers manifold on it thanks in advance guys

My eyes! I know your period (.) works because the ".91" shows up just fine.
I used an HX50 but that's no matter here as a lot of stuff still applies.
Tips:
A mock-up engine on a stand is your friend. It's nice you have that.
Vibrant makes a nice stainless bellows section for the turbine inlet pipes (part number VIB67632).
Buy a mixed bag of 2" mandrel bent exhaust pipe pieces from ebay.
Save the manifold-end flares from the original pipes. They're stainless but can be successfully welded to mild steel pipe with the correct wire or rod (based on MIG or TIG).
There are many ways to skin a cat where the collector is concerned. I used the factory 95-97 collector and a 4"x1/2" piece of angle iron to both mount the collector and had it machined to adapt the original T4 collector to the T6 turbine housing that was used (unnecessary in T4 to T4).
Your pedestal height will vary but mine is made from a piece of 3/4" plate welded to a 1" plate that is bolted to the block.
The lower plate is also the sealing surface for the block o-ring feeding the oil through a line to the turbo.
The drain uses a 5/8" piece of stainless flex tubing and a machined adapter in the fuel pump hole.
Other than that, it's a bunch of test fitting and time.

The plan is put a vband in each uppipe along with vibrant bellows my main concern is the turbo drain to the fuel pump hole trying to make something that will fit there without leaking or anything thing but we will see stuff should start coming in next week if all goes well in mean time any pics or ideas are welcome thanks guys

Here’s another question for you guys what kind of driving characteristics should he expect with this turbo his truck is a 99 crew cab short bed it’ll have a t500 stage ones for now 3:73 gears 305/55/20 and a local built auto with triple disk converter mainly curious if it’s gonna be laggy or not all info and opinions welcome hopefully everything will be in in the next few days so we can get started

Well bunch more stuff came in an fittings and hose and stuff came in for turbo oil supply and drain from JEGS while we where ordering we went ahead and ordered all the fittings for his fuel system probably a bit over kill but where using all 8an pushlock and fittings planning on ordering a walbro pump and a sump next also got a yellow tape box in to bought a fuel rail crossover for it and hpop gasket and line tool next gotta get hpop sent off

Few questions for you guys we ordered 10an drain hose and fittings for turbo is that large enough I went off what several other build threads had for sizing we also went with 6an for turbo oil supply which I’m hoping won’t be a problem anyway just share any and all opinions are welcome probably went a little overboard on fittings and stuff but he plans on keeping this truck a long time so he’d rather do a project once than twice
