I was looking at some of the dyno’s and the 8474 just did not look like it had much to offer, well I guess that was the top end anyways. It shines in the mid range? As long as it’s no larger than the 8374 then I should really consider it.

Maybe Team can chime in, as I don't remember exactly nor want to go down the rabbit hole to find out, but it has same max power output as a 9180 but much better low to mid range flow? I'd figure for another $150 its a no brainer. Unless you're getting an 8374 somewhere else for cheap.
Okay, It looks like Turbosource/turblown is getting the 8374 back in stock, so I will be purchasing soon. I have a couple questions I wanted to run by you guys before I do.
Is the main difference between the iron and aluminum CHRA weight savings? Is there a big need to get aluminum?
What EFR wastegate canister is best? I was thinking medium boost which is about 19 psi. My goals are a solid 400-450 hp.
Also, I'm going to get a speed sensor and the Inconel turbine housing shield.
I believe the medium actuator is 12psi (that's what I have) then you can use a boost controller to get up to 20 or so PSI if that's where you want to go. Personal opinon, I'd just get the iron CHRA and save the extra cash, this is a street car after all correct?

Building for street and maybe 3-4 high speed touring days at our local road course, Hallett.

I did a little research. The issue with the 8474 is that it gives up between 500-750 rpm of response. It’s really meant for someone who wants to push to 500hp.
I don’t know if I will ever want to target 500 hp, but I don’t mind having a capable turbo. I think I will be happy with 400 hp honestly.
I want a very responsive system so losing as much as 750 rpm until boost worries me.
no, you only want the 8474 for pushing into 600+ whp. The thing is you’re not going to get anywhere near there on stock ports. It will be hard pressed to even hit 450 whp on stock ports imo. You can get to 550+ whp with porting and the 8374.
otherwise you’re buying the turbo from Turbosource/Turblown. So the answer is obvious; ask and follow their advice. Which is likely going to be the 8374 with medium IWG Turbosmart canister, but you should still ask Elliott.
.
you can get a feel for how porting and fuel type influence the end result; porting allows more flow at lower boost pressure, better fuel allows higher boost and it also coming on sooner, etc. So my previous comment about 450 whp on stock ports is somewhat conditional to that.

Got the turbo in and started mocking up where the turbo should be placed.
TeamRx8 should get all the credit for giving me this orientation idea, otherwise there is not much room for an equal length runners.
Likely this is very close to the final position however minor adjustments can be made to the y axis and to the compressor orientation.
3.5 inch down-pipe should fit without issue.
I plan to cut the bottom of the coolant thermostat holder and weld an AN fitting to that location.
OMP may fit without sohn adapter.
I’ve been looking at getting this for a heat exchanger for water to air cooling system, but it’s been out of stock for a long time.
✔️sxe362 turbo .88
✔️450whp 93pump gas.
✔️old dyno 4,000 pounds
✔️I wanted more hp but my injectors reached their maximum.
✔️With efr8374 turbo and 0.92 you do 450whp easy. maximum 500 or 500 to 520 with e85 fuel.
unlike your ported Cosmo RE, his is a stock port REW.
It’s established that it takes low-mid 20 psi boost to get an EFR 8374 to 450 whp on a stock port REW. Shouldn’t be a problem on E85, but the highest stock REW port result I ever saw on same was ~490 whp at 29 psi boost. So it needs porting to reach the potential.
Don’t want to say much before we have an actual result, but we’re still working on the low-mount turbo manifold, though not using the shorty design. It’s taking a little longer to do since the off-the-shelf piping with appropriate flow sizing isn’t going to work. This is requiring us to jump through some multiple-sourcing hoops to pull it off. Assuming we do.

When I bought my 8474 through full race, they advised me that the Iron CHRA was the better choice for rotary application due to the high EGT's. It took almost 9 months to actually get the turbo in btw.
Proof I have not totally slacked over the holidays.
Mounted the heat exchanger. Had to make custom brackets. Everything turned out really good I think. I should be able to duct the incoming air and hopefully the most forward hood vents will make it low pressure behind the heat exchanger.
I did open up the front firewall as much as I could.
What do you think about this placement? Any cons? Do I need to do anything to make negative pressure behind the heat exchanger? Open to constructive criticism and discussion.

Not sure if anyone could or would say anything definitely in placement. Ideally you just want flow across the heat exchanger to be as unrestricted and smooth as possible. From the pictures its hard but I don't think it's the most ideal location without ducting. Upside is heat soaking won't impact the water temps directly.
I plan on mounting my intercooler directly to the AC and Radiator. I am hoping that with a hood opening and some ducting I should get good flow through all 3.
