3.2 intake & backfires?
 

Just exchanged my 3.0SC CIS for an EFI system using a 3.2 intake.

Still get things finalised, but have gotten to the driving a little up the road and back stage.

The EFI tuning needs work, I am backfiring, The CIS had the backfire blowoff valve, but how does the 3.2 manifold handle thing?

I appreciate that the 3.2 aluminium intake is stronger than the stock 3.0 intake and airbox - but can I damage the 3.2 intake manifold through backfiring?

Thanks in advance

You can split the rubber elbow and I have heard of the barn door tweaking from a backfire, but compared to the CIS system the 3.2 intake is tough.

Charging, what am I missing?
 

Have recently had my internal regulator alternator rebuilt.

Had the engine stripped for another project and took the oppurtunity to have it redone - I had never been confident it was putting out properly.

While it was out, I replaced the earth wire and cut back the positive and tack wires to reach good wire (34 years old) soldered and heat shrunk all connections.

Now I'm not charging at all, red charging light stays illuminated full time and volt meter shows no charge.

I am confident of the repairs to date, looking for advice as to where else to check, before I pull the alternator and recheck everything again.

One other thing, my oil level guage immediately pegs at over full with ignition turned on and/or engine running. Not sure if its related or just another gremlin which crept in whilst "I was in there"

Being you went EFI, I assume you are not using an AFM. More than likely a MAP sensor with possibly a MAF? If so, those are pretty safe I'd think for backfires and the intake will easily handle one being cast aluminum. Popping that rubber union coupling would be pretty tough to do too.

You're probably fine.
