Icon7 F23a block+F22a head=202hp

A hugh thank must first be said to:

Joe at Locash racing for the great tune and time taken with some trouble shooting.
Rosko racing for the custom parts.
Jeff at CHR Racing Products for the head work.
Steve at CCC for the great intake work.
Bisimoto for his custom cam, header, and valve springs.
B&R fittings for custom fuel line and oil catch can.
I'm sure there's some I missed and I appolagize.
The set up is as follows:

Block:
F23a bored to 87mm
Balance shafts removed
OEM TSX pistons and rings (revers mounted and valve reliefs fly cust)
Custom light weight Pauter rods
OEM bearing's w/ main bearing oiling holes drilled out bigger.
Endyn modified oil pump
Custom crank scraper (bitch to install)
ARP head and main studs
OEM 2 layer head gasket

Head:
P&P w/ valve job (head flows a little over 300cfm)
Milled 0.010"
OEM valves, Locks, and Retainers
Bisimoto springs
Bisimoto rocker arm spacers
Bisimoto custom level 3 cam w/ .480" lift intake and .503" lift exhaust
AEM pullys and cam gear
B&M fpr
RDX 410cc injectors
Roscko racing fuel rail, IAC block off, and EGR block off.
NGK spark lug wires

Exhaust:
Bisimoto custom header
Rs*R exhaust mag exhaust
2.5" high flow cat and test pipe.
-exhaust is funny fitting.

Intake:
Bisimoto IM heat shield gasket
Blacktrax intake manifold spacer
-ported TB opening on plenum to 70mm.
CCC ported H23 intake manifold taken from 8 ports to 4 ports
3" intake w/ Bpi flow stack and K&N filter
Omni 70mm TB

Transmission:
H23 5spd w/ F23 fith gear
Fidanza 8lb flywheel
TXS 6 puck clutch

There is prob. more that I've forgotten. It was able to put down 202hp from 6700rpm-8000rpm. And 156lb/tq at 5100rpm. The motor wanted to keep reving but stopped because it was so flat and no need. There is still more in it. Once it hits about 5000rpm it just takes off like a rocket. I have a dyno chart that I will try to post.
There are some idle issues that need to be sorted out but all in all very happy. If there are any questions just please ask.

Sweet. 'Bout time someone made a 200WHP SOHC F-series.

What do you think the compression is?

compression is around 11:1. I'm going to put a 3" exhaust and either a bigger cat. or another test pipe on it and see if it will hit 210. Should be able to.

I would love to see some in-car vids of how this runs. I am working on almost an identical setup.

Keep up the good work.

I don't want to sound crtical but it seems pretty low on torque. I'd expect something in the 170s. I am also curious on how the car idles. Is this a streetable setup or is this a dedicated drag/track car?

What would you price this build at if someone were to duplicate it?

Congrats on the numbers!

i think its the exhaust hurting him a bit, if its the exmag exhaust, thats like the ws2, great for sound and a street car but not for power.

what was it tuned on

yes its a street car. Idle is wacked right now. I'm trying to get the IAC remote mounted to help this out. When the IM was welded up for the 70MM TB they closed the hole up for it.

When it does idle its very lopey, sounds like a V8. Sorry but no vid. I have a couple pic's I can try and post. The torque is not bad its still an improvement of almost 20lb/ft over the last motor, so it def. helps.

If I had to put a price tag one it I would say about $5000 w/ head work and custom header. This along was $2400 of it.

it almost looks like it wants to make about 210-212 but something is choking it like an intake or a small exhaust...

It's the exhaust. I want to up grade to a 3" exhaust and 3" cat. or test pipe and have it re-tuned. I should see the cork come out at that time.

I told Joe I would be happy with any thing close to 200hp. On the first real pull it did 197. He let it come to an idle for a sec. then turned off to cool and said, well were done your close, lol. Thats when he called you. He was pretty supprised as I was too.

The dyno said it was 100* in the shop when it did this number and the intake temps were a consistant 110-112*.

Thanks Scott that means alot coming from you. Go luck on your single cam build and getting the H22 squard away.
