S2000 injectors have a reputation for springing leaks and being expensive to replace, if I have picked that up correctly, while there are no known issues with Prelude or ATR injectors?

Though... Pics of the injectors?

TPS is the same then
Looks like egr valve is different connector
Distributor definitely different, as expected - A5 has more pin-outs (I suspect due to having the tdc sensor built in where a7 doesn't)

Louckie? How do they compare to yours?

will take pictures tonight and post guys TIA

I had S2000 injectors on mine and they worked fine but you have to make sure you buy the right year.

Yeah, so you are definitely running an a5 distributor and egr off an a5 as well.
I assume they put an a7 short block in (i.e. swapped ALL ancillaries and engine loom from the previous engine).

The A7 egr connector is different, but if the a5 egr bolts onto the a7 manifold, just swap it and happy days - no fannying around. That leaves the only question being the injectors.

It's literally just the electrical connector that we need photos of on both of sailor's cars and louckie

The more I’ve been looking into this the more it’s juat twigged

That I doubt the vehicle is even running an ATR ecu

It has a standard inlet dizzy and exhaust manifold

The wiring loom again is standard. It is literally an A5 with a jumper up engine producing little to no more power at a guess

Oh yeah, I'm sure it won't be running an A7 ECU.
The ECU's on 5g's were coded to the igntion key (immobiliser yo) so they wouldn't have wanted to fanny about with that...
The ATR exhaust manifold doesn't fit a 5th gen lude unless you modify the front cross-member.
Short block A7 into otherwise standard A5 prelude by the looks.

Little update

Purchased black world Racing 68mm throttle body

Purchased ATR INLET

Purchased Hondata S300 V2 with obd1 to obd2a harness

Now my questions are.....

Do I have to run an EGR valve and the runner plate or can I blank it all ?

What injectors do I run..... ATR head and ATR injectors ? Although I’ve already tapped the holes to plug the secondary air feed for injectors ???...

As far as I’m away I have to run a 2 wire Iacv is there a walk through on this anywhere thanks in advance

Sorry guys for the late reply...I been busy lol
Yes, I can confirm I had an injector leak on my 04 S2K. It wasn't the seals (replaced them all) turned out to be leaking from the body where there is a little hole.

Replaced all 4 with brand new OEM from balade-sports.
My search on s2ki.com/forums found pics with same leak. They are Keihin injectors.
