any of you guys know the turbine outlet diameter for the 60-1?

 

Find dimensions here.....

JET

 

keep in mind the 60-1 on the TN kit utilizes a 4 bolt t3 turbine housing as opposed to the typical t4 turbine housing on normal 60-1s

( I was having a discussion with a Supra guy who told me supras running 60-1's make 550-600whp so I looked into the turbines those guys were using versus ours heh)

 

thanks JET, i guess, as far as i can see, its 2.75", does that seem right.

 

I'll find out for you. I can tell you that the 60-1 turbo (compressor section) can come with any turbine you want. The Turbonetics kit uses a Stage V turbine wheel and housing with a .77A/R Tangential and 4 bolt discharge. I have a turbo sitting on my file cabinet at home and I'll measure it tonight.

 

thanks, just measure the exhaust turbine outlet diameter, id appreciate it.

 

Will do.....looking for a new turbo?

 

OK Tig, what are you thinkingof doing?

 

I'm thinking of a GTK turbo for him

 

lol, nah, im thinking the exhaust turbine outlet on the aps turbo is too small, its 2.5 inches for gods sake. they make a 3.5 inch downpipe and suggest their exhaust, but they have all the exhaust going into a small exhaust housing and being forced thru that 2.5 inch outlet. just doesnt make sense. im looking at getting a different exhaust housing with a 3 inch outlet and for an external wastegate.

im just want to see what size the TN turbo has.

 

Gotcha, I'll check that when I get home. And there my friend is the issue with internally wastegated turbos especially when you try to run a large turbo with an internal gate. What type of turbine inlet does that have? 4 bolt T4 or T3?

 

yep, 4 bolt T3 i believe.

 

tig apologies but last night by the time I got home I forgot to measure this for you. I will do this tonight...

 

its gotta be a turbine housing backpressure issue. i did some measuring last night, the turbine housing is .63A/R, meaning no lag, no top end. i think the turbo is the GT35/40R, the compressor wheel measures out to be a 40R wheel so it cant be that. but that A/R is terrible. they make a T3 4 bolt 3" outlet turbine housing that i might just have to buy, but it uses an external WG.

 

.63 seems really smalle for that much airflow. The Turbonetics uses a .77 A/R just to keep spool up times decent but could probably go bigger...You could weld a wastegate mount on the last merge pipe. Either that or try running to wastegates one at each maifold exit.

 

Tig its 2.75"

 

thats what i thought, thanks mia.

 

No worries. If you want to try a different turbo hit me up. I'm sure I can find a turbo you would want for a nice price

 

haha, i think i might just change turbine housings to the .82 AR.

 

Tig, if you go ahead with this plan, keep us updated.. I was planning on installing external wastegate anyways.. Good luck with your R&D!
