Snapped a few pics of both GZ lower intake manifold and oil pan.

Runners on intake are much straighter moving upper intake forward.

 

and now side by side with Mazda oem LIM....

 

Finally the GZ oil pan....

 

All look like well engineered pieces but everything is always great in theory so lets see how that lim really helps on the dyno as well as the oil pan reducing flex between housings.

 

Nice, I wonder how it compares to the RE LIM? Looks like it really cleans the manifold up.

 

what exactly is that hole between the primary runners for?

paul

 

Why wouldn't they go ahead and enlarge those runner a bit? They look the same size as stock.

 

How much was the GZ oil-pan, and where did you get it ?

Let us know if there are any clearance issues.

Happy New Year!

probably has something to do with the ports on the motor. they more than likely assumed that the average buyer would simply slap it on the motor w/o port matching. if you gasket match the LIM and not the engine (which would be somewhat hard to do with it STILL in the car) then you would have flow problems, fuel atomization problems, and so on. i think it was a good idea to leave that to the owner of the car.

whats kinda odd to me is that the LIM/UIM flange seems to sit more "forward" than stock. i would assume that would cause fitment issues.

the runners look a bit thick. . . which is NICE. that means there is PLENTY of room to open up.

very nice piece.

also, this piece looks like it might have fitment issues with the stock twins. . . has this been taken into account?

As Tom93R1 stated in the previous thread about this LIM (https://www.rx7club.com/showthread.p...1&page=3&pp=15) He talked to GroundZero at SevenStock and they said that it will not work with the stock twins due to fitment issues.

 

Lookin' good JD

Too bad they won't work with stock twins/BNRs.....re: the oil pan, how much is the capacity increased?

 

Why wouldn't work with stock twins? Do you mean sequential?

 

The stock turbos and the GZ LIM want to occupy the same physical space, most likely. Thus, you can't run both the stock turbos (or upgrades that are outwardly similar) and the GZ LIM on the same engine at the same time.

What are the weight differences between the stock oil pan vs. GZ oil pan. Stock LIM VS. GZ LIM ?

That's what really matters!!!

 

im willing to bet the flow might matter more than a few ounces of weight difference.

paul

 

common now, I know you RX7 owners have a sense of humor. I know you do...!!!

I'd still like to know the weight.

 

Does this oil pan STOP oil leaks - yes....no...

Tom

 

If you seal it right I'm sure it will.. My buddy installed the upgraded Pinapple oil pan with the oring and it leaked. He coated it with silicon and it fixed the problem.

 

Aren't the Pineapple and GZ oil pan the same thing?

 

I dunno ?

 

Looks like the exact same thing to me?

i think they are the same thing. . . and gargamel. . . sorry about the uh humor thing. . . kinda hard to figure out someones tone on the internet. . . besides, this forum is so full of blowhards lately its almost an expected occurance.

paul

 

Hehehehe, I wonder what car those parts are getting installed on. Muahahahaha(Dr.Evil laugh).

 

mm from what i can see..the ports look the same!! i rather keep my re and shave and cut the emmisions off of it..make it look clean and have better flow..i was hoping the ports would be better..yes it does look like there is a bit you can port out..but i rather have the re manifold and just port and pollish that and still be ahead? amd i right?

but i will wait on flow numbers and dyno numbers..and than decide i guess

 

Did not see where the stock oil level sensor bolted on. How much is the oil pan ?
