I'm going to go ahead and ask this here first, because I figure there's a plethora of guys with leftover pieces...

But does anyone still have an intact 2.5 intake manifold that would let go for dirt cheap? The throttle body area is busted off on mine, and I'm looking to do some R&D.
I haven't junked all my leftovers yet. So I have the 2.5 Ford IM. You can have it if you want, just need to pay for shipping.
 
I have recently flipped my MZ3 but the engine is still working. The car is totaled and I am looking into the possibility of buying a same car that has a dead engine and putting my old engine in it. Do you think this would pay off? The engine spent 1hr flipped and it still starts but has a cloud of smoke coming out of the exhaust, probably oil but could also be the transmission and coolant fluids. It is a 2010 mazda3 2.0L engine with 148HP and 135000 miles. Before the crash it ran smooth.

The critical question is how long was it running upside down before it was turned off? It doesn't take too long to damage an engine if the main and rod bearings are no longer getting oil. The cloud of smoke you see is probably from oil seeping past the rings and into the combustion chamber while it was upside down.

The car wasn't running upside down at all. It turned off immediately. It is manual transmission so stopping killed it right away. How can I clean the engine from that oil that is now everywhere on the inside? Thanks!
 
I went to that dyno meet but after the first 3 cars put down just short of 2000 hp combined, I figured I'd spare myself the embarrassment. :laugh: The weakest car in the 3 hours I was there was a Focus ST that was still doing 2x what I would have put down. It was almost exclusively V8 cars, some of them boosted. Lots of 500-600hp Vettes, CTS-Vs and Mustangs. Highest was a turbo WS6 that did 840whp.
 
A little group of douchey trolls in the crowd didn't really help much. Meh, a local Mazda group mentioned having a dyno day. If they do it I'll go then for sure.
 
Currently working on a solution for the 2.5 intake manifold.
Buy a throttle body spacer for 2.3. Countersink the bolt holes and JB weld some nuts inside the countersink so you can bolt the 2.3 TB to the spacer. Drill and countersink holes in spacer so it can bolt to the 2.5 intake. Now bolt the spacer to the 2.5 intake and then bolt 2.3 TB to the spacer.

I also noticed that the 2.3 turbo (Mazdaspeed) throttle body appears to have a similar mount pattern to the 2.5 one but it looks like it has the 2.3 throttle body electronics.
 
Wouldn't be hard to make the spacer from 1/2 inch nylon with nothing more than a Dremel and a drill. You'd lose the 2.3 mani's dual stages though.
 
From what I understand, the 04-05 didn't have dual stage manifolds anyway. It sure doesn't look like it whenever I have it off. You're talking about variable length runners, right? And yes, between the two of you, that's essentially what I'm doing. A friend of mine had started tinkering with carbon fiber, and offered to try making me an adapter plate.

All 2.3s came with VLIM. That's what those two vacuum solenoids on top of the manifold are for. One of them actuates the VTCS, one is for the VLIM.

I'm not sure if the genpu 2.5s used a VLIM. If so, that would be the one to get.
