Anyone know the difference between the pre-6/99 and post-7/99 manufacturing dates for 2000 model year Fed-spec VQ30DE-Ks?

Is it anything that'd affect swappability into a 4th gen?

 

Swirl vavles in the lower IM(post 7/99).
Pre have none. But most post 7/99 still only have one nipple on the Vias
Mine have none

 

I thought only Cali-spec models had swirl valves?

 

Nope........

 

I have seen swirl valves on one post 7/99 Fed DEK, though the production date on that engine may have been listed wrong. All the pre 6/99 Fed DEKs I have seen all have had swirl valves. Best bet is to look at the motor before you buy. If the VIAS actuator has two nipples it's got swirl valves.

 

There's nothing that would affect the swapability of any model year DE-K into a 4th gen.

 

Lies

My expierences different

But you are the one with the DEK's in your garage so I will believe you

 

Didn't the '01s not have EGR?

 

that is true, but with a 95 ecu you can go without egr.

and if you have the swirl valves, you can always remove them and jbweld the holes

 

True you can get any DEK, but as people have said the 01s don't have EGR and some '00s have swirl valves which is just more work to remove.

 

DEK engine count - 3

Again I think the yards confuse the production date and the pre and post stuff seems almost irrelivant. You have to go by the damn VIN # of the car to get the exact specs.

 

Thanks a ton, guys. Just ordered a 7/99+ 2k DE-K. Tilley will be doing the install on Wednesday. Wish me luck, and no more damn oil burning....

 

I believe I saw some EGR quipement on my 2k1 DEK.... I'll look again and snap some pics.

 

Well, maybe the shop I got the engine from had bad data, but the engine definitely has butterfly valves. Bummer. It was supposed to be a >7/99 Fed spec.

EDIT: It's still awesome though.
