Stock turbo with leak stop equipped DV (slams shut upon spool), WM, and tuning with an err to the timing side of things (4* peak on IX, 7* on VIII) should be plenty for breaking traction from a roll at about 3800rpm.

Timing can really be felt but doesn't really help things if knocking or overly rich

 

Thanks, this is the type of insight that I was hoping for... so, what is WM?

 

2.3+3076+Race Gas= LOTS OF TQ

Scorke

 

that is some insane torque there, scorke!!! some pretty impressive spool-up for a 3076r, even with a 2.3L.


I'm shooting for like 400 - 450wtq to hit me by like 3800rpm!

 

Find Evolutionary's previous build that hit 340wtq by 3000rpm and around 420wtq peak.

 

I wonder if I should be looking into a TR30R or a GT28r, I just don't want to lose all of my top-end and end up like a big truck - all torque with no top-end...

 

If all you want is tq do a stock based turbo, specialized cams, high compression, and displacement an d you will have more tq than you know waht to do with.

thanks, I'll look into that - sounds like what I'm trying to achieve here.

 

Get in touch with TurboDynamics in Britain. They distribute the Forced Performance 5-Blade 20G, machined, billet aluminum, compressor wheel in the U.K., and they do ballbearing conversions too.

You definitely want the FP 20G compressor wheel inside of a IX compressor housing. As for the turbine wheel, since you want low-end torque, I would stick with the lower-mass Titanium-Aluminide turbine wheel found in the JDM RS turbo as opposed to the higher inertia Inconel LT wheel used in the Evogreen. You can even go 9.8 cm on the turbine housing since you to want to maximize low-end torque. Have TurboDynamics outfit it with their Ball-Bearing center section as well.

This should spool and have gobs of lowend and lower-midrange torque. It should hit reallly hard. It is essentially a White Rabbit IX, or BR 20G-9-5 fitted with the JDM RS Ti turbine wheel and a 9.8 cm housing, spinning on ball-bearings. If you were fully nuts you could finish it off with TurboDynamics´ surge ported IX compressor housing with the 4" inlet bellmouth.

Now, this turbo is gonna cost a pretty penny. As a practical matter you could have essentially the same performance out of a Forced Performance White Rabbit IX with a 9.8 cm exhaust housing. Just call Robert and he´ll fix you up.

 

2.3L all the way

 

thanks, sparky... (I sound like Clark Griswald there... )

So, the 20g compressor wheel will help torque over the standard 16g?


Also, I don't suppose I could get an FP green LT turbine wheel made out of Ti-Al? add some ball bearings to it, and I think this would likely be the perfect DD/street turbo...


Not really sure how to run the stock MAF while using a 4" ported shroud on the inlet side of the turbo...

 

Dejontool makes a sick piece, 4-3.18 which is maf size, order one from there any color you want with whatever tubes you need.

^^^ I take it that this reducer doesn't negate the desired anti-surge effect the 4" shroud has?

 

Look, the stock 16G turbo as Warr and Scorke(nice engine bay!) have already pointed out, produces some great low end torque numbers on stock block Evos. It's hard to beat the stock turbo for low end torque production.

I don't think that the 20G wheel is gonna give you better low end TQ numbers than the 16G compressor wheel. In fact, because of the larger trim it'll tend to slow spoolup down a tad and move the torque up a bit higher into the rev range. It's just such a beautiful billet piece and produces great power up top.

I am just thinking that if you'd like around 400+ WTQ by 3500 w/o drugs or a displacement increase, that you'll need to get creative. At the same time, you don't wanna go and break the bank by purchasing ballbearing cartridge coversions, 4" shroud compressor housings, plus international shipping costs.

No, the 20G wheel and/or the 4" shroud aren't gonna help much with low end torque production. It's still hard to beat the stock 16G turbo's lowend torque numbers on a stock block. The stroker motor is a solution, obviously, but it too isn't cheap.( I'd love to see a comparison of before and after torque curves on SmokedMustang's 2.3 Liter stroker(before w/ 6.5 TME, and after with the 20G-LT).

You could have FP configure you a Bizarro turbo using the larger "LT" turbine wheel inside a hogged out 9.8 turbine housing, but still retaining the smaller16G compressor wheel wheel inside a IX compressor housing.

A Bizarro like this should spool like crazy from 3000 RPM on up and produce HUGE lower midrange torque. This would be kinda hard to control boost on with the stock internal WG however, and might surge like a *****. It should spool like crazy though with the big turbine spinning the dinky compressor wheel and keep power down in the lower part of the rev range. This configuration would be a IX-LT, and as far as I am aware, no one has tried it yet.

I still think that I'd prefer the WR-9 as a good fast spooling option, since it has the TiAl turbine wheel, the 5-blade 20G compressor, and the IX housing, while it won't break the bank.
