New S13 Sr swap issue

[atmsanchez]

Finished the swap today and when we where testing it noticed that the car has no power. You step on car and car barely moves. It starts, idles and revs perfect in neutral. But as u drive in any gear car does not want to go. It is on stock boost now. any ideas what can be the cause?

[OnTheChip]

Weak fuel pump, broken FPR, or clogged fuel filter are possible causes.

[atmsanchez]

Fuel filter is new input the 300zxone ill check other 2

Check timing as well and did ya'll compression test it?

[ultimateirving]

Timing seems most obvious. Also check ECU for codes might tell you if something else is amiss.
and for new swaps i always always insist on boost leak testing. You never know what is leaking that you overlooked

[atmsanchez]

Changed pump already no change, trying fpr and timing next

[atmsanchez]

Well it that it is on timing and changed fpr. I am lost it is crazy. U step on gas and it is like I are doing the opposite

What ecu codes?
Did you pressurize the whole system?

[atmsanchez]

Well rechecked it again and now it on timing. Driving little better. It has some power now seem till starts to bog at top boost. Might have to see about doing a boost check. Also as I was returning from around the block. Blew a small coolant line on bottom passenger side. Now need to wait til it cools


And only code is 55

also on stock plugs you should be gapped around .032 i believe, somthing to consider as SR coil packs arent known for their hot spark

[atmsanchez]

Car is running better with some power but still when it gets up in boost it starts sputter bad

I changed to iridium

[ultimateirving]

I changed to iridium

can you please tell us what the part number is from the plugs. and what gap did you set them to. You CANNOT trust them to be pre gapped from the factory.

Ill will check tomorrow and will check he gap also and let u know.

Found the problem. I took coil pack and coils from my other 240 and now car runs perfect. Just checking now to see if its the coil pack or coils themselves.
