Time for a new turbo

[Sir Psycho]

Well the HE351 with external gates has been fun but really only at freeway speeds. Want something that will smoke the tires a little bit faster off the line (spool earlier). I've been reading compressor maps all morning but want a second opinion.

I'm shooting for 300 hp at 20 psi with a mildly ported 531 head. So on a map that equates to a 2.36 pressure ratio and 300 cfm I believe.

Needs to be a T3 and under $350 in good used condition as well. Me thinks a 19t is a little small and an HE351 too big.

Something like a small t04e, stg3 turbine wheel, .63 a/r should do. Or a GT2871

if you can find a used/working one it's a good tester for sizing(and at a very low cost). should spool pretty well with a header and dna took one over 300hp

what's more important, the final whp number or the quickness of spool?

 

[Sir Psycho]

Quickness of spool. More streetable power. Feels like a dyno queen now.

I've been wondering the same thing. Been looking at ebay turbos, but still not sure what size would be best. Something that spooled around 2-2.5k in second gear would be great.

Hahn Super 16G should be pretty much what you want, even if it's not a T3 frame.

 

[Sir Psycho]

Please, I don't need another reason to kick myself for not buying Sam's. Are there any T3 to Evo adapters?

 

[Harlard]

No dude, this would be a near bolt-on. Normal scroll, with T3 flange and 10.5 cm^2 turbine housing (looks like they scaled up the 12B design).

Probably the best turbo out there for a mild Redblock build (and it's soooooo cheap for a new unit).

 

[Sir Psycho]

My HE351 has a 9cm^2 housing but it does look good. Not sure if I'm that good at viewing compressor maps to compare it to the Holset.

 

[Harlard]

Pretty sure that it would spool very nicely, especially with that tube header. I have read reports on these doing very well in uncorked motors with 90+ manifolds.

 

[Sir Psycho]

Got any links on hand ?

Ive been using a he341 and it spools prety quick. Full boost befor 3 grand .

 

[Sir Psycho]

With what set up?

Nice statement. Its not about the total power, its nice quick streetable power. Make a good setup on gas, then supercharge it with some E85 for a little bit more over the top.

Whats full boost? 8psi wg pressure or 30psi full tilt boogy?



Kenny made a statement thats so true, the AR of the housing, becuase its bigger doesnt necesarily mean slower spool.

Find a way to adapt that 20g I have?

 

[Sir Psycho]

Trying to find compressor maps for the HRS 16g & 20g

300hp, fast spool, here are some great candidates/things to look for:

t3 super 60, t04e-40, 'big' 16g, maybe even so far as a t04e-50, but that's going to be pushing it a little I think. bullseye has some great spooling turbos in the same size range, but you may be spending more money.

Maybe KKK24?
