I own a s5 turbo 2 with a jdm motor.

First whats the differences between the usdm motor and jdm one?
Ive tried to find the info to no end...
One thing i do know is it doesnt have a fuel cut.

Any links would be great.

More questions to come.

Ignoramus

I spent a minute searching and found some info. Google is a big help.

There's no major differences, just minor things and emissions.

jdm s5 block unknown internals, hybrid/upgraded turbo unknown specs as of now, internal bov, stock manifold, stock jdm s5 ecu tuned to 12psi by KS Engineering same place as rebuild, racing beat down pipe/test pipe, intake filter, Bov stock tmic for now, i dont know rebuild specs but it is jdm everything, no fuel cut, walbro 255

Question is can i run these spare rc racing injectors i have sitting around there 650cc, on my secondary fuel rail, because the stock one in there are old and not in the best shape

Whats a good boost gauge to get?
Boost Controller?
Fuel Controller?
Fpr?
Fuel filter?
Were can i get a total new emissions deplete kit so i can redo what was done already?
Ect...

I just am trying to figure out what more i should get, also ive seen and am familiar with racing beats products whats a few of there simple mods that will make the car last longer oil, cooling, ect...?

It will be a daily and am trying to save as much money as possible on these parts, i want parts on the cheaper side but are good quality,

Also it has heat range 6 and 9 plugs now non platinum ones needs a tune up
I should replace with ngk platinum ones right, but what heat ranges?


any help is greatly appreciated

Thanks in advance

Boost gauge won't really matter, just get whatever you like.
You can manage boost off of the stock wastegate spring, a manual boost controller, or an electronic one. Manual (mbc) is the cheapest way to crank the boost easily, ebc's are nice but a lot more money and not exactly needed.
Fuel controller? Are you considering an aftermarket ecu or a piggyback? For my build I chose a haltech computer. It's nice to have full control of my system and to get away from the stock computer.
I have an aeromotive fpr. Very high quality and definitely worth the money! no complaints..

It was a Gxl at one point but has a N/a dash thats why i need a boost gauge.

Stock ECU is not tunable. JDM or otherwise. The only exception I know of being Rtek 2.x series modified ecu's. Hope they ported the turbo wastegate while they were in there.

Those injectors will make the car run richer above 3800rpm. Probably not rich enough to cause misfires, but definitely way richer than necessary because of the walbro-induced higher fuel pressure. Since you have an unknown hybrid turbo, it's hard to say what will work.

If you do get a tunable ecu, you'll probably want to go bigger than 650's because you won't get much more power out of those injectors. Really depends on your power goal for the car and get everything to support that number.

For plugs, use 7's and 9's. Or all 9's if you're making lots of power. I don't find the platinums necessary, but it's personal preference.

Heres some of the turbo pics i will clear everything out the way and take better pics at another time.

Yeah i couldnt find the chip it has a wire sticking out the side like it once did but not now sucks theres also instructions in japanese and KS stickers that i assume say void if open ill take pics next time i pull the ecu out and when i take better pics of turbo also.

i know re amemiya has a chip like a rtex like one of those black boxs attached to the side of a chipped ecu or whatever it is

Here's the details of your knight sport modified ecu. Yes, it does exist. You are not nuts.

Google Translate : http://www.knightsports.co.jp/

If you want your car to run correctly, keep everything exactly the same as the ecu is a modified unit and only programmable by knight sports I believe. If you want to change your injectors, turbo, etc. look into a programmable ecu wether it be a modified oem unit like the rtek or a standalone like the powerfc.

i knew i wasnt nuts as im a jdm fanboy and have seen things like this.

But what do i do now since that said mini black box is missing? lol

that link just linked me to there home page ive been there.

You have to see the jdm instructions attached, i knew i should of taked a pic when i pulled it out to inspect also the harness ground thats by the kick plate for the ecu wasnt grounded i went and grounded that. should i have?

The chassis and suspension is worked, besides coilovers, maybe ill have a build thread one day.

I'm not sure what the mini black box is that you are taking about. Fuel cut defencer?

Ah yes thats prob what it is for a us model lol never mind on that.

So i do have a tuned ecu right its claimed to be tuned to 0.9 bar.?

which i believe is 12psi

What could the little black wire be for sticking out of the ecu's side?
Maybe something like this below, what is this?

Does this make any sense to anyone?

I will also post a pic of the taped on paper instructions in japanese later have to pull it again. And of the whole unit.

Does anyone know how to read japanese?
Can anyone confirm KS Engineering is Knights Sports?

I can understand why you guys scream WHY? its cause i cant go standalone yet, im in debt and this is what i got, gotta work with it for now, plus if i know what i have i could sell it later down the line.

Im pretty sure my KS turbo upgrade, consist of a ported wastegate and maybe a bigger rear wheel, stock front turbo part, but i still dont know yet either i will have to pull down pipe off to take a peek in there i think i know what the differences are...
