I just installed a T4 on my '01.....so I have some Dorman uppies, a modded stock turbo with DieselSite WW2 (rebuild with a 360 bearing) and a delete pedestal. PM me if you are interested.
Guys I just wanted to give a quick update since I bought a new part for the conversion.... from ebay. Please dont wait for a install/review since im putting this kit together little by little. There are other truck maintenance thats a little more important right now.
Im open to the criticism from buying it on ebay. But I liked the price and the number of people that have purchased it before, gave me some peace of mind... some.
I bought some just like that, think they were $129. Was pretty surprised by the initial quality for the price. Fit was good, no issues installing them, has been 2 years now. Make sure those come with the collector flange, not just the pipes themselves.
They look just like the ones from Irate Diesel. Two things that stand out to me.
The still seal to the heads with RTV so not much gain there.
Just a flat plate with a spigot welded on. No contour to help air flow.
My thoughts are only worth what you paid for them.
I would agree with HD rider on the mating surface. RiffRaffs plenum are more expensive but they seal awesome. And if you have to remove them and an o ring tears install new ones and good to go, no scraping off the old junk and a long clean up process. Never have had any leaking issues out of mine at all. One of the best things I ordered when I did my E99-L99 swap.
Looks like you are on your way. I will agree with Colorado 350 and go with some quality up pipes if you are doing this.
I wish I would have known as I just let go a rebuilt gtp38 with a billet wheel and deleted pedestal with 2k miles go. 3” plenums with inserts, and 17 degree Bosch pump with 10k on it.
If you need any parts let me know as we are in the middle of rebuilding 5 motors, a van SDmotor, 00 forged rod motor, and 3 obs motors.
All of the bolt ons are going in the scrap pile and the heads, front cover, crank, rods are all that are to remain. If you need anything let me know, that goes for anybody....
Lastly regarding plenums. People get carried away with the aftermarket plenums. Are they an improvement absolutely, have I purchased installed them-many, but I will note for your circumstance or 90% of the builds on here they are absolutely not needed. Put your money else where maybe in the up pipes.
For that chitty rtv, id like to find someone who actually can claim they blew it out. I have cracked 6.0 coolers before I ever blew a plenum or even had one leaking after resealing the first time. Personally have banged on my personal truck from 25-47 psi since 156k and now at 720k, still hold 60psi on a leak test without leaking. Stock plenums with that worthless rtv :-) more than sufficient for your setup.
Yes billet o ringed pieces are pretty and have their function.
Also save your 80$ on the high flow outlet. Takes about 5 min with a die grinder and center punch to knock out the rivets on the butterfly, buy a 1/2” freeze plug and after pulling the rod and butterfly seat the freeze plug and stake it.
If it were my truck, I'd do the same thing. I'd keep the EBV though, so I could run a decel tune.
It opens up so many more options at far better prices.
