2F turbo (13 Viewers)

[flaminbandit]

just been for a play as i finally installed a tacho one of the main reasons why i had nfi what rpm i was getting boost
im hitting 15psi at 2000-2100rpm in 3rd gear
also realised im only reving the engine to 3000rpm acording to the memory tacho LOL


im gonna swap boost controllers im nto really happy with this new incab controller i brought getting a boost spike to 15psi even when its set at 10psi

its all fun in the land of turbos

Is you turbo dialed in on the FJ40?

 

[Mace]

Not yet, but I did work on it this past weekend.



I finally can start with the actual pics..

 

[speeed_dmonx]

ROCK ON MACE! I CANNOT WAIT TO SEE...I am contemplating a 292 with a turbo....just to try it...I look forwards to your pics my friend...

 

[Mace]

alright, I got the parts to rebuild the turbo and reassembly

Here is the adapter.

 

[FLYINGLOW]

Mace whats the adapter made from? Stainless? Do you have a couple detail pics you can post up?

I have trashed my header and my exhaust is pretty rusted so I pulled a manifold out to put on... I started thinking of brewing up a turbo as well, still learning about stuff though and found your thread. I will run it with the TBI and hope I won't have to do anything with the computer.

 

[Mace]

The heat riser was removed and a new plate fashioned for where the stock intake manifold bolts to the stock exhaust manifold.

 

[Mace]

Then you start assembling the turbo to the exhaust system and incorporating the waste gate.

 

[Mace]

Three steps,
1st pic - Turbo bolted to the stock exhaust manifold.

2nd pic - Stock intake manifold attached, and plumbed to the turbo

3rd pic - Turbo intake plumbed. The carb sits on the top of the last pipe.

It is a simple Draw through turbo setup so no need for enrichment under boost.

The adapter is mild steel (unfortunately the damn thing has rusted significantly)

I don't know exactly how many more pics of the adapter I can take,

The easiest description is to take a stock downpipe and weld on a T4 flange on it with the wastegate coming off of the side.

It is a very simple setup.

LOL!

It must look different in person because that is not how i would describe it.

It is a very simple setup.

Thanks Mace. My only problem is that I was saving a stock downpipe for ever and threw it out a couple years ago cause I couldn't forsee ever needing it again... Now I can't remember what the stock flange looked like, I know there was a donut gasket in there somewhere too. I'll hunt around for a flange to use if I can find a turbo cheap enough to go through with it. I have an ARB to buy or fix first and then I'll see what the budget allows...

Maybe this should be called "Tailgate Turbo Build"

The bolt pattern is an offset 3 bolt round system.

Kind of annoying actually. All three legs are a different distance apart. Not like a standard 3 bolt header flange.

Ya I noticed that... Just got the remains of the last broken stud out of my manifold last night.

 

[FJ40Jim]

Mace, it looks like you made space between the intake & exhaust for the heavy duty exhaust blockoff. Has the bottom of the intake been milled off, or the top of the exh, or maybe both?

 

[Mace]

bottom of the intake has been milled off.

To tell you the truth, I am not sure why.

I have not identified what makes the block off plate necessary..

 

[badass]

Mace i'm thinking about starting to make these now that i actually have to the tools to do so. hmmm... Ok so the adapter consists of one t3 flange which i can purchase from any turbo website, but i'm thinking i would have to custom make the 3 bolt toyota flange.

Anyone know if the 3 bolt flange can be purchased anywhere???

Then i had a question about where the wastegate mounts up to the circular portion of the adapter. Is that a common flange? What is it called? And i don't see any bolts, how the hell does it mount up?? Or is that just a universal circle that you welded the flange to? Thanks.

I like the big blockoff plate.

I see it as protecting the bottom of the intake from the excessive EGT that can pile up in front of the turbine under heavy load.

If the engine is running propane, then no carb heat is necessary, so it would help performance to divorce the intake & exhaust.

 

[Mace]

on top of that, the carb is mounted on top of the turbo intake instead of the LC intake (so not heat there either). I suspect that you are correct about the EGT issues on the aluminum intake manifold..



Badass, the stock flange could be used, but I think that a thicker flange would be a good idea

And, I am running a T04 Turbo instead of a T03.

The wastegate flanges typically come with the wastegate. Pretty simple..

 

[badass]

ok, so mace what do you think is a better flange to use on the adapter a t3, t4 or t3/t4 hybrid? Assuming all that actually exists.
