And finally here are pics of the motor build, courtesy of Derek from Innovative Motorworks We are still waiting on the bearings before the build starts

Block finally back from Benson Sleeving

Pistons, crank, rods installed


almost all together, missing a pivot bolt on the chain guide, have to get thru the dealer so we are waiting on a new one


me and my friend picked up our built motors

And so it Begins

Motor almost ready to pull

ready to pull

lifting out

empty motor bay

new twin going in, flywheel on

clutch disks and pp on

going back in

 

all 4 mounts bolted up, wiring underway

pulled my knuckles off to install buddy club ball joints

new ball joints are in the knuckle

radiator, battery, front bumper bar re-installed, as well as cruise control deleted

mounted and wired up my new AEM digital gauges

installed my RBC, fuel injectors, fuel rail, and fuel feed

clean up the engine bay, installed my ktuned throttle body bracket and cable, tilton cmc, and a few other things

mounted up the intercooler

and mounted the turbo manifold

ran some of the ic pipes, mounted the cmc resevoir, bled the clutch, still need to hook up the injector clips, run vacuum lines and hook up the turbo when it comes

body is back together

intercooler pipes hooked up, fuel injector wiring done..... now just gotta wait on this turbo. but when it comes just gotta clock it, hooked up oil and water lines and boom

car is back together, back on the ground.....

 

 

finally have everything hooked up. well still need to extend boost solenoid wires, and mate up the 2nd piece of my downpipe then fill her up with oil.



heres the first startup vid

This is from D-Rob's thread he created. took the quote out so pics would show up

"As some of you know the twin scroll EFR 8374's have finally begun shipping, and a customer of mine ("Jeff122886" here) was one of the first to receive one of these puppy's.

Yesterday, he made the long trip from Boston (7 hours each way) for some welding, engine break-in, and finally pump gas and C16 tuning.

His previous mid-pipe was constructed by what looked to be a blind baby with a MIG welder, and was thrashed up pretty well by the road. Below is the old versus new, because there's no use trying to make a bunch of power with a fancy new turbo through a crushed exhaust.



The turbo sitting nice and comfy in the engine bay of the RSX. It's strange to see a Full-Race divided sidewinder without gates on it!



Finally, the car on the dyno.



The engine was fresh (we assembled the engine over the summer, Benson-sleeved 87mm/Wiseco 9.8:1, Manley rods, etc...), so we did a small engine break-in on the dyno, changed the oil, and went for the lowest boost pressure setting available with the actuator on the turbo.

I was amazing to find that the internal gate was able to hold boost wonderfully at low pressures, with nothing but a small increase in boost over engine speed.



Next was to turn the boost up with the integrated solenoid. Upon applying duty cycle, I found that boost did not significantly move up until about the 50% or so range with this actuator. We also saw that while the internal gate does a great job bypassing exhaust flow to keep boost down, it still carries the same characteristics as most internally-gated turbos, in the way that once pressure goes up, it has a tendency to spike, then level, and ultimately fall off. That being said, I was able to make about 20psi in the middle, and 17.5psi up top with the first actuator, with controller duty cycle at 90% or so from 7,000 RPM and higher.

Below is a plot of the boost pressures on pump fuel. It is a comparison of the "high" setting, and the "low" setting after some preload adjustment.



With that said, the final 93 octane numbers were 508whp / 410wtq @ 20psi falling to 17.5psi up top. Because of this boost taper, the torque curve is a tad wavey up top. The engine's torque curve holds on, while boost drops. The dotted line shows wastegate pressure with a slight 1-2psi creep, so the curve looks normal.



After learning of the gate's tendency to drop boost pressure, a slightly stiffer actuator was installed while the 93 octane was pumped out, and C16 filled in its place.

The new actuator's lowest setting was around 14-15psi, and with that we were able to make about 25psi up top with 90% solenoid duty. In the middle, there was enough to make 28psi or so, but for the sake of consistency, we tuned to a flattened out 25psi.

At 25psi, we ended with 640whp / 480wtq.


As with the other gate, we saw a spike in pressure on spool-up, a slight drop, and then stabilize. The spike in torque on spool up can be seen on the pressure plot below.



Here is a comparison of the final C16 plots versus the final 93 octane.



Over-all, the turbo seemed to make similar power to a 6262, but spooled much like a GT3076R on this engine.

Here are a couple comparisons versus similar turbochargers:

EFR 8374 versus GT3582R


EFR 8374 versus T3/T67 H.O. (car with T67 is 11:1, on E85 even)


The EFR 8374 is hands-down one of the most responsive turbochargers of this size that I have dealt with.

Thanks for taking a look, just thought I would share the results.

nice thing prob a beast

 

640 whp........oh my god

 

WOW this thread is dead.

 

its sad theres more people searching for what leather seat to buy for their tl than a fullly built honda integra

 

Seriously !
WOW that was some cool reading !

 

Nice build dude!

 

Holy shit! Absolutely mind blowing. Congrats to you sir

 

got a gopro, better vids to come in the future

 

and one more, this one is better, shorter and just highway pulls

 

damn

 

diff angle, kinda like this angle more

 

epic

 

that camera angle is sick, kinda reminds me of playing grand turismo in car view. lol

 

love your RSX great job

 

freakin sexy!

 

nice numbers!

 

This car is fantastic! Can't wait for the full race turbo kit in my tsx!!! Great job man, car looks awesome, and the engine is unreal!

 

Wait wait wait, i just saw it says Worcester Area! Like Mass?

 

yes, Worcester, MA haha.


will have a bunch of updates in a few weeks or so.

teaser pic

 

no way??!? Where are you getting all your work done? Car looks amazing...idk if you are apart of masstuning...but there are a bunch of meets and things coming up..you should definitely go cars great http://www.facebook.com/groups/18385...6564120709849/ list of upcoming meets and things

 

i do everything myself, except body work and motor internals

 

Wow...respect, good for you man! Thats fantastic! Can't wait to see it at one of the meets

 

bump for updates

 

Wow

 

Holy F*%$ that thing is out props, I think you should go lower though.

 

heres a few more

 

Wow, can't believe I just came across this. That car is bad ass for sure

 

Fucking sick, nice work man

inside view

next run after with a mustang

so much more room to grow. working on the launching thing

 

 

Beautiful car bro, very nice engine work, I admire this and full respect for you and that beast.

 

sooooo SICK !!!

looks greats and its FASTTT !!!!

 

guess you have a following now haah
