Hi,all

I have a challenge for you..Help me sqeeze 180whp out of this setup..
This car is a track car and there's a power-to-weight ratio to take into consideration.
Also some things are not allowed to be changed..

The b18c4 is the european version of b18c1 (GSR)..

So here goes

IM must remain OEM and we're not allowed to port it or anything.
Not allowed to change pistons,rods,crank..The block must remain untouched
We can change the head to another OEM head
We can change the TB (but since we can't port the IM is it any use ??)


Currently we're at 163whp with the following:

Hondata s100
AEM intake
DC JDM 4-1
metallic cat (2.5in)
skunk2 catback

It dynoed stock at 140whp...

I was thinking an ITR head ,but according to c-speedracing 'howto' it would lower compression and we don't want that..
I can get some Skunk2 stage 2s for a good price, but are they overkill ofr this setup ??

All ideas are welcome..

 

how much $ do you have to spend? smsp/headertech, etc., those headers are the best.. 2 layer HG with some stage 2 cams? comptech icebox intake.. if you're staying all motor, you'll want to bump compression as much as possible so you can run stage 2 cams. good tuning is a must

edit: and of course the IM and TB but i haven't done much research on which would be best for an all motor setup..

 

To get the full power out of those cams you would need to upgrade the valve train, and raise the compression. Also where do you redline at, you would want it at around 9200.

As for the TB and IM i think the Type R TB and IM would be a good setup if you have to stay oem. Get a better header as well.

 

so you can change the head internals right?

-skunk stage 2 cams/skunk valetrain
-type R head and intake manifold. (it only lowers compression 2-3 points, so from say 10.6 to 10.4:1. not a big deal, PLUS it flows a lot better than a GSR in stock form)
-hondata/AN-R intake manifold gasket
-make up with the loss by switching to a 2 or 1 layer headgasket. which ill increase the comp a lot.
i assume you cant mill the head?
-bored type R throttle body to 66 or whatever it goes to.
-better header like AN-R, Bisi, SMSP, Hytech, etc or similar custom one.
Hondata s100
-AEM SHORT RAM intake
-casound cat 2.5"
-Hytech exhaust if youre a stunna and have their matching header, SMSP likewise
that would probably get you ther if not further

Agreed with everything you said except the intake.

Go for the J's Racing Intake

 

im just a believer that intakes dont make the world of difference people make them out to be.i HAVE seen dynos where J's made 4hp over aem, but SGT i think did a test and on a stock ITR the stock arm and airbox made like 3 peak over J's...basically its all a margin of error in my eyes.

 

type-R or B16 gears with a 4.7fd, if you dont already have them.

The limiter is at 8800 now because it's still stock valvetrain I don't want to blow it up

Type R IM is no good without the type R head. It won't bolt up to a GSR head

Yes we can change the head. We are not allowed to mill it

Compression is only 10:1 now..Then it would end up at 9.8 er so with the ITR head..Guess the head gasket can compensate a little bit, but still ???

I was suggested by a fellow HT member to go for this:

Type R TB
Skunk2 stage 1s
cam gears

Think it will give us the extra 15hp or so ??

 

He's got two gearboxes. One from a b18c6 with the 4.785 FD.. He says the gearing is too low and he prefers his B16 tranny.
He would like something in between the 4.4 FD and 4.785 ,but is that even possible ? I haven't seen any aftermarket FDs that are not either lower than 4.4 or higher than 4.785

 

we don't have to go for the stage 2s it can also be stage 1s ..Maybe CTR cams ??
I think it would be good to get a better midrange and not only peak hp (but he's very focused on that )

 

Hi ce.
Perhaps these cams would work well with that setup:

Itr intake arm w/ k&N Filter Vs Js' Racing intake

On my setup (check bio), i know its not a stock motor, but this kind of power is not a "margin of error"
