[quote name='mazdaspeed7' date='Jul 14 2005, 06:52 AM']The downpipe is definately aftermarket, is that divit th eonly thing that made you think its a j-spec engine?

Yep. After that, there are no differences as far as engine. If the wiring harness is routed towards your driver's side, then that's a giveaway as well.

The "divit" in the DP is not there for the steering shaft... ALL FD's DP's have that divet, because that is were it pass's the frame, it only have about a 1/4" clearance. The steering shaft passes threw an indention in the frame on either side, and the indent is on both sides of the frame whether is is JDM/USDM.... The DP means nothing!







Yeah, and JDM engines have no emissions.... (or no AVCR's, and EGR's.... as if that's new https://www.nopistons.com/forums/pub...R )

Nope. That's wrong. A Petttit downpipe will not fit a JDM car. I HAVE TRIED. My HKS one will. If the steering column wasn't there, I would have WAY more than 1/4". Probably over an inch of clearance between the frame rail.

Ohhh, nevermind, my bad https://www.nopistons.com/forums/pub...1047683664.gif





Yeah, but that still doesn't mean it's a JDM engine https://www.nopistons.com/forums/pub...IR#>/happy.png That acctually looks like a stock cast part, but I remember seeing an aftermarket DP with a cast upper part....





But yeah, maybe they just bought a DP off of ebay....

Yeah, I actually mentioned that in one of my previous posts that I jumped to conclusions about the motor. The US and Japanese motors are identical anyways. It's the UIM/LIM/dp/wiring harness that are different.

[quote name='jspecracer7' date='Jul 13 2005, 01:35 PM']Okay, after looking at the downpipe, it looks to be an aftermarket one...possibly HKS? Either way, that downpipe was made for jspec FD...so my assumption that the motor is jspec is flawed

i think its an hks. it looks like it fits better than the other more tubular fd dp's

hah just wait until 75k miles.

wont be my problem

Little bit of progress today. Mocked up the radiator and oil coolers, just need to weld the mounts(piece of cake).

Ill be removing the 2 cross braces for airflow reasons, and replacing with a single, stronger piece, farther forward. You can also see the second oil cooler, a stock FD piece on the drivers side brake duct.

Im ready to hang the RB turbo back exhaust, as soon as the exhaust hangers come on(wednesday). I cant wait to see how close the RB presilencer flange will be to the fd downpipe flange. Im sure its going to be close, just how much is the question.
