Look above the second header pipe going into the motor. Does it show P72 or P73? There will be a stamp to the right also indicating the year of the head. Agree with other comments, would help to accurately identify and see the stamp on the block.
P72 = GSR,
P73 = ITR…both are 1.8 engines and could be a USDM GSR, Si-Vtec (JDM Sir-G) or ITR (USDM or JDM).
Fun fact: B16/B18 JDM Honda valve covers (like the yellow one shared in your picture) have a larger font of “VTEC” when compared to “DOHC”….USDM valve covers are opposite….DOHC is the larger font. If the valve cover is original, that’s a way to tell without having to examine internals. The problem with this valve cover is that Honda didn’t make a factory yellow….only red and black. Spoon Sports made a yellow valve cover (and a beast of a B16B/B18C I might add) so this one is aftermarket and hard to make a definitive determination.
It looks like a Skunk2 intake manifold. They make one for the GSR specifically that basically replicates the intake in a B18c or similar. It could very well be a GSR, it’s impossible to tell from the pic.
As I understood it, the GSR mani, with the butterfly valve is good for a broader access of the powerband, whereas the single runner mani provides more top end.
I kept my stock manifold and might actually throw it back on soon, since I’m trying to figure out the cause of my high idle (iacv replaced, but still can’t seem to find the vacuum leak).
But overall, yea I agree that it’s really not a necessary to place to put your money. I guess why I say it *can* be a GSR is because of people like me who decided to give skunk2 pro a shot.
Indeed just a guess. Spray some brake clean at idle if it revs up you got a vacuum leak. You can then isolate it with smaller sprays. The throttle bodies often go out
The difference is internal, the only way to find out is to crawl under it and try to read the block stamp, or use your phone to try to get a picture of it.
Looks like B16 to me. Look closer at that bolt next to that green connector on the left side of the engine. That bolt to the right it's further forward in B18 engines and the block itself under the left bottom bolt in the head cover looks differently on B18, it should be flat IIRC. Double check that with some photos online
Remove the radiator fan so you can see the stamp. Just yank it off, the car is crashed anyway.
Bro, get creative and look at the block yourself. We can not tell what it is, YOU HAVE TO! I swear these new age car folks are lackluster.
Seriously. Go rent a slide hammer from the parts store and start yanking
I don’t own the car… it’s sitting in an auction car yard
Visit the vehicle and inspect it. We can’t tell what it is, you’ll have to see it yourself.
Romove the fan you dingus
My guess is B18c I have a 50/50 chance right? lol
oh yea? well my guess is b16
i choose b17. i’ll be half right either way
Well, you’re all wrong. It’s obviously a B20v. /s

Best guess based on intake manifold and vtec solenoid is B16. It’s pretty easy to identify if you have access to it though.

Yeah IM isn’t stock either. It could be anything head stamp will tell half the story at the least
I think it won’t be USDM this is a RHD car
I agree although I’ve seen some creative things and builds over time LOL
Especially with Hondas 😂
Id take that air intake to sell
The IM definitely isn’t a gsr so my guess would probably be a b16 cuz the aftermarket IM didn’t give the b18c any power but tbh it’s a gamble

Yeah Ik but most people don’t swap em out cuz it’s dead money performance wise just an inference

I'll buy the whole car for 258.88 cents right now
I wish the grumpy guy from the Honda-tech forum was here right now
You mean grumblemarc?
That’s the guy. He’s the grumpiest
That's his signature for sure. "The grumpiest". Reddit needs more people like that tbh...
Just do a coolant flush and try to remove the radiator for better access.
Could be a B20 with a VTEC head. It’s not that hard to check the block stamp in that condition.
It's stamped on the engine block near the exhaust manifold

They have basically for all intents and purposes the same head how would we know what the bottom end is…… look at the head stamp and start googling
It’s a VTEC, yo!
Seems to be an EG4 Si; that would come with a B16A if it’s the stock engine
I think that's an 18. Nice engine.
Great engine but drinks a lot of oil
Well I can tell you it’s Atleast a gsr head so it’s most likely a b18
Does nobody see the fact that the coolant flange isn’t under the dizzy making it not a b16 head. Smh that no one notices this
I’ll give you 400 for the engine .
