Yakozan's JDM Spec-R

[Yakozan]

i was kinda suprised when I saw the readings.

I think they calculated the engine power a little high.
when I calculate with a 15% transmission loss I get about 284hp @ the fly

Well well. still good
To bad the EBC wasn't setup properly Could have been a little higher.

Topper, get your exhaust bits on and get those extra horsies :thumbs:

 

[Topper]

I have tried but cant get the car high enough to get the bolts loose

Car is going in for a service next week, so will have them on by the end of next week :thumbs:

 

[Nicely]

:nod: I get 286bhp using the quite accurate calculation (rwbhp+10 /0.88). Its just an estimate really. Better to use the RW figure. Even then its going to vary from Dyno to Dyno...

 

[Topper]

241.5 rwhp is still good :thumbs:

Think i got 228.8 rwhp, will see later in the year how much its improved :thumbs:

well the only thing engine spec-wise differing between our cars are the exhaust bits.
Get those changed and you would probobly have more then what I've dynoed.

I got my result with a peak boost of 0.74bar

 

[Topper]

And a Walbro, which i havent fitted yet either

My peak boost was at 11psi, around 0.75 bar :thumbs:

Would like to see the difference the Decat, Frontpipe and Elbow make. but it can wait :thumbs:

Quite a bit. They are three of the four main restrictions in the exhaust circuit.

lol
the best performance-wise would be to run without an exhaust

Most people change the cat-back first.
For performance you should change the other bits first as the exhaust gases are hotter there and needs more space.

Fit that walbro topper It's plug n play on the S15
the hardest part was getting that plastic lid back on.

Nicely's got a good guide on his site. I used that one for support. Didn't really need it as it was a pretty straight forward swap.
But it always feels better to have a guide next to you when doing it.

 

[Nicely]

The S15's exhaust isn't nearly as restrictive as the S14s. That's where they get most of the 50 extra bhp from.

Denso IK24 sparkies and braided brake-hoses on the way :thumbs:

Shopping Spree madness

Had quite an shopping spree today.
2 new Falken FK451 tires has been ordered. And I just made an enquire to Apex about some Ferodo pads for the fronts

Slowly getting the car track ready

The BBS wheels came with a close to new set of Hankook tires in the back and pretty good SNOW tires for the front

So I ordered the Falkens for the front SSR rims...... Confused yet

This is my plan.
Daily driving.
front: SSR rims with new Falkens.........rear: SSR rims with old tires.
Track.
front: SSR rims with new Falkens.........rear: BBS with close to new Hankook in the back
Drift and donuting.
front: whatever I feel like....................rear:BBS snow edition in the back

Hopefully I'll get all the tires sorted for next year.
Don't want to bin perfectly good snow tires and don't want to put new tires on the BBS because I'm thinking about going for racing tires next year.

Getting there Just need an Aero kit and spoiler and you'll be set... :nod:

Wouldn't mind a full aero kit minus the rear wing

Will try to afford a nice aftermarket (yes, crack edition) kit for next year. But there are so many so I don't know what to choose.
And I also want a Power FC, and coilovers, and big brake kit, and widebody, and bigger and wider wheels to match, and Nismo gearbox, and new turbo, and cams, and new injectors, and so on.

 

[Topper]

Better get saving :nod:

black washer bottle looks nice will have to do this if i ever decide to remove the inner guards haha

With the FMIC I had to take the plastic mesh out in the front and move the washerbottle a bit. It then lit up like a christmas tree in the front so had to paint it

Just ordered 2m of braided hoses and some Earls econ-o-fit fittings.
Soon I'll finally be able to connect that Oil catch tank which has been waiting under the bonnet since like january

Hmm. 2m might be like a meter to much. But there might be other things to bling up with some braided hoses aswell

It doesn't help with being parked next to that...thing. Your eyes are repulsed away from it straight onto your washer bottle...

Yepp. But now it's black and stealthy.
The "thing" is quite fast though. almost 400hp. boosting about 1.6-1.8bar
But with Ford quality He's on his third gearbox and recently blew his head gasket.
It looks abit suprised or should I say shocked with those headlights :rotfl:

It's kind of a nice picture though. The beauty and the beast (S15 being the beauty, and the Cosworth starring as the beast.)

Picture was taken by a guy called Viper89

 

[Topper]

Nice picture, your washer bottle needed painting for sure :nod:

 

[Yakozan]

OK. I was in the garage today and started to prepare the rims for some painting action. After removeing the centercap I discovered that they where 8J wide :thumbs:

Put one coat of black on one of the rims and it turned out real good.
Forgot the camera at home but I'll go back tomorrow and paint the other three and put additional coats on.

I'm planning on doing some track action on the 15th of July at Mantorp Park. the same weekend there is a King of europe drift event in V?ster?s. On the friday there is some drifting for the public which I hopefully will try with my good looking snow tires and then head to the track
My mate with a GTI-R will join me for this trip. Shuld be great fun if nothing breaks down

Recieved my Ferodo pads from Apex today. Just waiting for the tires now and will order some new oils from Airtune.
Last week at work before the vacation too. So everything is comming along Nicely
