Heavy bogging under boost and bogging in low RPMs?

[Z32]

Hi, if I just start cruising on the streets at about 2K RPM, my car starts bogging unless I give it more gas. And today I took the car out and punched it, 1st gear felt very weak and in 3rd gear at about 5k RPM car starts bogging. Right now I have at small boost leak on my TB shaft seals and boosting at about 9 psi and I recently did a compression test and these were my results 150 150 150 140. Is there anyone out there who can identify my problem? I would really appreciate it.

what are your spark plugs gapped to?

That, I dont know. Same plugs that came with the cdar when i bought it. Do you think the gap could make this problem?

1. NGKbpr6es or 7es at .028".

2. Time for a boost leak test.

3. Was the afpr set up properly?

I did a leak test and found a leak at my TB shaft seals, but I would have to buy a used TB in order to fix that because no one sells the seals. On another note I'm running only 35 psi of fuel pressure to help lean my car out a little because it runs way too rich and I stink at tuning AFC's. Could the low pressure be causing this?

Send a PM to Oldman, He may have the TB shaft seals you need for a 90 TB. There is no need to buy a replacement TB.

Merry Christmas Brad.

Z32, yes I still have one more set of seals for 90 TB, pm me if you want it.
