Thread: 4BD1 Isuzu (/Perentie) Budget Turbo Install

Turbo intake:


From memory the costs were:
Manifold $280
Turbo (ebay) $300 (T2560 from a Nissan Silvia S14 SR20DET)
Mandrel bent 3" full exhaust and custom dump pipe $500
Turbo oil feed T and hose $130 (enzed)
Misc - bolts/hoses/flanges/clamps $300

Boosts to 21 psi with wastegate wired shut.
On the highway at 100 it sits between 4-10 psi on the flat depending on headwind.

Some tips and tricks:
You will notice I used socket head cap screws wherever possible. 7 years later and they are all fine and none have loosened. The turbo adapter is just sealed using VHT copper gasket cement. For the dump pipe and other exhaust gaskets I reuse the original gasket with a thin coat of silastic/RTV each side. RTV is the best stuff for exhaust/manifold/turbo gaskets.
Wastegate is wired stut.
Water is not connected to turbo (you can see water connections in one image)
The only time I have needed to touch anything on the turbo/manifold setup in the last 7 years was to R/R the starter. I still have the winged sump so it is easier to get at from above.

Sweet Writeup, from the looks of the setup there is no IC, do you feel that an IC could be plumbed as it sits?

No I haven't installed an IC (yet?).
For the boost levels I am running I probably should be, but 6+ years of hard work and counting things are still OK.
I am halfway through building a laminova-based intercooler into one of these manifolds. But a bunch of things got in the way. Maybe in another 6 years I will finish it

Wow, that is interesting, I've never heard or/noticed an intercooler incorporated into a manifold, pretty interesting.

Why I like using intercoolers, is from my own experiences I've found the IC to be an Insurance Policy for the motor. I've seen 2 turbo's let go below, and both times when I have pulled the IC to clean it out (backwards) I emptied a lot of chunks of the impleller blade. In my mind if the IC wasn't there than those would be in the motor.

I have just recently been in contact with matt mcinnes about building a laminova for mine, i think i had to use 3 or 4 cores and it was going to take up a fair bit of room. So i just ordered a water to air from plazmaman instead. 😊
