Not exactly what I expected, but I think I'll hit the 200whp before the end of summer after I change a few things.



Mods:

JDM B18C (GSR)
Balanced bottom end
Eagle rods
Bored .20 over
11:1 CP pistons (teflon and ceramic coated)
Teflon coated bearings
Alaniz ported head, 3 angle valve job
Skunk Stage 1 cams
Skunk springs
Skunk retainers
Skunk cam gears
Skunk intake manifold
Hondata heatshield gasket
RC 310cc injectors
Walbro 255lph fuel pump
64mm throttle body
Fake J's intake
JDM DC 4-1 header
Carsound 2.5 cat
5zigen exhaust
Exedy 3 puck clutch
ACT 12lb flywheel
JDM GSR LSD tranny

Tuned with Hondata s100.

I forgot to get a print-out of the A/F ratio, but let me know what you think.

Thanks to Hybridynamics for building and tuning the motor.

mind you, i'm new to the whole built engine HP levels, but, 180hp from a relatively built B18C1 is pretty weak...

am i wrong?

 

I chose these parts expecting 200-210 whp, so no... I don't think your wrong.

I say "mild built" because of the Stage 1 cams and 11:1 CR.

 

maybe the dyno reads low? try getting it timed.

 

higher compression and some bigger cams would have taken advantage more of that ported head...

 

The header, exhaust and intake will probably be changed soon. If that doesn't make an improvement I'll buy a set of bigger cams and mill the head.

you could add a one layer gasket instead of milling.. But, you could also do both

 

intake - get the ITR cold air by AEM
header - a GOOD one, ie. SMSP, DTR, RMF, ANR
Exhaust- free flowing 2 1/2

you should see around 190-195 tuned right

get you some stage 2's and you'll break 200

exactly and add a one layer head gasket and go with rocket motorsports m22s and youl probably see 210+whp

 

it's a good midrange....but replace the header....with a smsp or hytech...and if u got money left over..get a skunk 2 stage 2 cam.

i put down 197 and 131 dynojet whp/whtq on a stock block stock headcast us type R motor..just valvetrain and a mugen HG.

 

Some better headers, and some Rocket M22's or skunk2 Pro 1's with more dynotime will get you pass the 200whp.

 

Better header, cams, intake manifold and intake and you should be able to get close to 200 whp.

 

They put a velocity stack on there and picked up 3hp in the top end. The midrange stayed the same.

I'm going to do some research and find a good header for this set-up.

I forgot to mention that I still have the power steering hooked up.

 

don't get a one layer head gasket it won't last a long as a three layer making it that you will have to keep changing it and that's a pain in the ***. but get a cai intake, a better header and some bigger cams

 

When tuning we noticed his car pulling a bit of vacuum so when we finished his tune we tosed on a 3" short ram w/ a Prototype Racing velocity stack to see if it would help. Sure enough it did and fattened up the power 6500-8000 rpm by 3-5whp w/ no gain in peak. But this was a heat soaked run compared to the one in his graph so I am sure peak would have been a few HP more considereing it was a bit leaner too. We were having some sever heat soak w/ this car and runs were hard to keep consistant.

BTW the car has a Cat and P/S too. So there is few more HP's lost compared to some of your setups

I am confident that you would have been in the 190whp range w/ a beter exhaust w/ no cat (Most 5 Zigens neck down to 2" or so through the resonators), the V-stack, and no P/S. Maybe close to 200whp w/ a header change.

Very nice car overall. It was one of the cleanest we have had though the shop

 

You spent a lot of money to make 180 whp

Do a compression & leak down test on the motor.

 

Thanks Denis, I'll probably run the car as-is for about a month or so and be back with some new parts to hit that 200whp mark.

I did, but it will allow me room for improvement and still keep it reliable.

 

i think those #'s are pretty straight on considering that most dyno with no catback on and no belts besides the alternator. They usually also never show the SAE corrected #'s like you did and instead show the STD uncorrected #'s which are usually higher. You might also want to keep in mind that they will also use a Dynapak and not a Dynojet which i think tends to read lower.

This guys a moron and probably has never tried a 1-piece head gasket. They are just as strong and reliable as a 3 piece.

But for reals get rid of the POS intake and get a AEM CAI for an ITR. I'm certain you'll gain at least 10whp from that simple swap

 

Ya, that intake may be holding you back some. I don't think the compression is your problem.

I made just over 200whp on a stock ITR block, & ITR cams, a few years back.

Have fun with what you got. Sounds like a few minor changes, and you'll be right were you want.
