Thread: Hori Turbo Throw Together

Ok so here is where we got to on Sunday.

I cut out the original intake on the air cleaner and siliconed and riveted a blank over it made of left over tin ducting.





Now that is done I'll get a 70mm hole saw and drill out the original drain and use it as the intake. The air cleaner will be installed 180 degrees from factory.

Once the intake has been swapped, the filter now has to be modified so it still cyclones. We tried prying it off but that wasn't working. After a while we cut it half way down and that gave us enough flex to slide it off. Once off we taped it up and slide it on the other end.

Apparently you can buy these filters with the cyclone on the other end, I'll try find a part number for it.



Next job was to rerun the vacuum line using as much original gear as possible. This meant making a Tee out of the steel pipe for the CDL and reusing the hose clamps. Unfortunately the hose was too short so a new length was run at both ends.



How about that sexy cable tying?



This is my spacer that will hold the EGT gauge. This spacer also sits the turbo away from the manifold so i can in future use a turbo blanket. They were mm away from each other.



And a test bolt up.



Next to do is the Oil Feed and Oil return and modify the dip stick. We thought we might get a RB25DET factory dump pipe and make a tractor stack just to test the turbo haha!

I have been thinking about running the intake behind the engine and below the air cleaner. I would rather run it over the engine but I can't rotate the compressor housing enough because of the wastegate.

Anyone got any clever ideas? Basically the turbo outlet points straight down.

Get rid of the waste gate not needed on 4bd1 diesels mine is disconnected most guys on here are the same binned

So what is limiting the boost? I know nothing about this turbo (other then it is waste gated to 12psi) and don't want to risk destroying it with 20+psi.

Grays sent a half dozen over to sell, it didn't really work out for them.

I did exactly that on my County. Clamped a short section of straight steel tube under the air cleaner brackets, and connected to it with silicon elbows.
It was part of a plan to perhaps run a barrel style WTA intercooler, but I've never got around to it.

Did it work out alright? Not too laggy? There is probably twice the bends going that way...

Boost is controlled by fuel .more fuel more boost ....bear in mind as is fuel wise as a n. a. youll get almost no boost you'll have to increase fuel to get boost hence fuel = boost and control of ...some of the factory 4bd1t had nonwaste gated turbos... forget all your petrol stuff... with diesel the more air the better
