Help Identify My Engine/ecu

[dantheman88]

Hi guys, im new to the forum but just recently bought a r32 with a half started rb25det conversion. Anyways i was told it was a r34 neo engine (which i was sure it wasnt). But now I need help identifying what I actually have so i can buy the right coil packs and power fc etc for it. I have tried googling the ecu numbers but nothing comes up.

So the ECU number is MEC-R521 A1 1077 and the wiring with is seems to be right for it. I was thinking it was a series 2, but I found a broken igniter that seems to fit the harness in the boot amongst a whole heap of other parts.

Heres a link to the car i bought

Well a metal CAS would mean it isn't a NEO since they all run the plastic one.

[dantheman88]

yeh even with my limited knowledge on rb's thats how i knew it wasnt a NEO.

[dantheman88]

also i noticed the bolt pattern on the ignitor wouldnt line up to the coil cover

[mad082]

engine number would also be a way to see what series it is.

[dantheman88]

engine number is rb25105495a. any idea?

[Bronx]

i think it should be a rb25det series 1 motor, the ignitor on coil cover lines up, the cas, and some bolt patterns/pipe plugs on the cam covers show its not a neo, i dont have half the bolt patterns or plugs on my neo.

[dantheman88]

no the igniter doesnt line up to the coil cover

Isn't that just for vin numbers? It's a conversion so it won't match anyway

Funny that it has a Neo timing belt cover though

the crank angle sensor has a mitsubish emblem on it too. Is that normal?

[PM-R33]

Yeah that's normal. They are a Mitsubishi item.

[dantheman88]

Oh ok. Well can anyone shed some light on this mystery?

[Bronx]

take the head off it you will then see, or if you have one of them long camera sticks you could shove it down the intake and through an open valve, check it out.

[dantheman88]

What would I look for then? Is there anything on the wiring loom or ecu that would maybe show a difference between a series 1 and 2 besides the igniter? Or maybe take the ecu somewhere to see what power fc would fit it? Or do the series 1 and 2 Ecu's use the same Power fc's?

if you take the head off, and you see the pistons, you can tell if it is a r33 rb25 or a r34 neo rb25, different pistons. and im also trying to figure out how to tell a series 1,2 and neo apart from one another.

Are you saying all r34 rb25det are neo's?
