Turbo BS Thread

Try some wd40. I haven't had issues stretching couplers. I had the issue of them being too loose. 80mm coupler sounds like a good solution.

 

No video from my trip. I wasn't going fast enough to film anything exciting. Barely got above 50mph.

 

There are 3.25" couplers. They don't come cheap though. HPS silicone couplers makes them. Quickest to my mind. There are others as well.

 

Just imagining all of the on/off throttle fun, is exciting.

 

Got a picture of that?

 

Any of you 2TR guys with turbos have a picture of where and how you did your oil drain?

 

Circled in red is where I tapped the upper oil pan

You can see it running down between the manifold, around the oil filter

And into the part on the pan I tapped. I used a screw-in bung, that has a lock on the backside that gets staked...Didn't have access to a TIG, but have zero issues with leaks

 

Can't nail down a good size set of twins for the 454, really hard to find what I need with T3 base.

 

I'm too lazy to go back through old pages, but are you referring to a 454ci engine? And trying to mate up T3 turbos to a motor that big??
Shit, even 5.3 and 6.0 LS motors want T6's!

 

I was going to say T3's would be way too small I'd think. 454's are massive

 

She's gonna be a low boost low revving old bird, well not old, it's all new and I've hand ported the heads to their limit... but I'm not chasing horsepower to the ends of the earth or anything.

I've got two NOS cast manifolds for T3 turbos. Thinking 61/62 Garrett twins

 

Idk, a 454 is gonna choke a T3/T4 turbo pretty heavily unless you have a massive hotside. You'll be making more backpressure than boost lol.
I'd go with at minimum, a GT40/ HX40/ S400 series turbo.

Even here, they recommend a large turbo: https://www.motortrend.com/how-to/junkyard-454-163-ebay-turbo-700-hp/

 

I could see that if it were a single, even a single HX40 is wayy too small. But twin 61/62 with .82 AR turbine housings is too small ya think?

 

Maybe go for a 1.06 exhaust housing to keep that backpressure down if you going for a gt3582

 

I'll browsed AGP turbo later and see if I can find a housing when their site is working

 

But you could probably run a .82 just fine. 3.4 tacomas typically run gt3582's with a .70 hot side. Half your motor is 3.7

 

I had the .82 on the 3.4 w/35r, moving to the 1.03. Shooting from the hip, for a 3.7 (x2), I would do the same. Maybe look at other people's results?

The new G35-1050 has a new 1.21 hot side available now. Could even mirror the turbos.

3.4 pron w/1.03.


.02 cents fwiw

 

So it's settled that the next I4 Toyota puts in the Tacoma will be a 3.7 because math and why not? #torque4dayz

 

I have since replaced that upper oil pan with welded in bungs, was getting leaks with these. The second one is for the AOS-R
