This motor has taken longer to build than anything I have done before. I am still waiting on a GSR head that I sent back East in February. The motor:
GSR block-sleeved by Dan Benson to 86mm.
Crower 92mm crank.
Cunningham LS length rods.
IB Spec Ultimate Wiseco 86mm pistons.
The head is a B16a head ported by Tom at Portflow.
Portflow valve springs. Portflow retainers.
JG custom sheetmetal intake manifold.
RPM 74mm throttle body.
RC 440cc injectors.
Hondata tuned by IB Jeff (thanks for all of your hard work buddy )
Custom Prototype Racing intake.
Hytech big tube Type-R header.
Two sets of cams.
Toda 'D's fully tuned on run #23.
Swapped in some Skunk 2 Stage 2 cams on the dyno and tuned them until we got run #34. Not a world record, but I am happy with the results for now.
Peak hp:255.9
Peak torque:175.1


We dynoed this motor back in September with a stock ITR intake manifold, and it made killer torque (178 ft.-lbs.) at about 5,200 rpm, but the motor was suffocating at high rpm. The change to the custom JG intake dropped the peak torque a bit, but upper rpm power improved dramatically.

I would like to thank Jeff at Import Builders (again) for all of his help with this project, Tom at Portflow for a great deal of last minute help when I needed a head done (Tom, you are the man!), Dan Benson for another killer block, and Eugene at Prostreet for letting us monopolize his dyno for so long. Thanks again everybody who helped out

 

god damn

nice

 

Those are good #s..

 

Good numbers, I need to hire you to build me a motor, all yours are beasts!

 

Very nice!!!!!! Congrats to you and also Jeff@IB! I gotta talk to him soon, I haven't spoken to him since early early this year! Hopefully you get your OTHER HEAD soon andc redyno and see how much more power you will make!

 

Very nice #'s. Congrats on the build!

What car is this thing in, and when you makeing a trip out to the track?

 

wow serious numbers. great build up time/effort finally paid off

 

Awesome #s Todd. I'm really interested in seeing the power output when you get the RLZ head

 

Very nice,my build up from IB to,were excepted huge numbers so i cant wait!

 

Time for some ITBs...

 

Wow, Another dyno showing skunk2 stg2 making more power than Toda D's. to you guys.

 

nice numbers

 

Nice numbers indeed...


Sorry if this is a stupid question, but what's the compression ratio? I saw the 86mm Wiseco Ultimates but didn't see a CR, maybe im blind. But keep up the good work, I wanna se 9's outta that.. hahaha

I was thinking the same thing. And an AEM EMS for good measure.

 

maybe you should try BC 4s since they destroyed skunk2s on Tbone's motor.

I'd like to see this as well.

 

Those are some damn good #'s..... 175tq What is this setup in? What is the comp ratio? This man definatly knows his **** and isn't a dick about sharing his knowledge

Do it! I would love to see 270 whp

Wasn't that skunk2s stg3's not stg 2?

Yes but the sk3's killed the sk 2's on my motor beforehand.
I beleive Jeff has better luck with the skunk 2's over the 3's though.. Just goes to show what works for one wont always work for the other.

Good Job Todd and Jeff sick tq

 

nice numbers

 

Nice, what were you aiming for? I would have thought the HP numbers would have broke 260's, but they are still very nice none-the-less.

 

Great Job, When are you going to the track?

 

sick numbers.....
