Wow Andrew (hotbox240) also broke a pickup tube...

Did you have the girdle bracket attached to the pickup? I have an S14 pickup tube that doesn't have the bracket...

94 and a healthy dose of meth, I think.

We don't have e85 up here.

Tariq, correct me if I'm wrong.

Correction, I've broken 2 pick up tubes. One on my stock block, and one on my built motor. Both cracked the welds that hold the strainer to the pick up tube.

I'm running a 35r .82 a/r & SLS T3 manifold. As for fuel I'm running 94 + methanol like Nate mentioned. My oil pick up tube broke just like hotbox 240.

I'm going to run a s14 pick up this time around...

what was that failure like? just lost pressure and shut it off? happen slow or fast?

and i hate to be probably to 30th person to ask over the years, but how does that 35 spool? i keep seeing them CHEAP. will this thing make 20psi by 4k if you hit it down low in 3rd or so? you ever had this thing on the dyno closer to 20-21psi?

Every time I've broken an oil pickup I never completely lost oil pressure. Typically I would find my oil pressure would start to drop off around 4k...I never saw it drop below 35 PSI though. Both engines were fine when I opened them up. However I can't be sure what happened in Tariq's situation...assuming it went to the machine shop it probably wasn't good :?

When I had a pickup tube break, it may have been weeks before I realized it was the pickup. Under normal driving it may not even be noticeable but yes it does drop off on high RPM and hard turns/accelerations when the oil sloshes and the pickup sucks up air.

Nice pull. I hope to have 500hp on pump gas one day :D

Unfortunately for me the failure seemed to have happened at the track or at least that's where I noticed it. My car had rod knock right after my first pass. I towed it back to the shop and noticed the broken oil pickup after the pan was off.

I actually ran my 10.99@130 with 21 psi and she comes on at 4000. Made 400 at the wheels at 21 psi (mustang dyno)

I just don't think a 35R will make 20psi at 4Krpm in 3rd. It will be well on it's way though. We had one int he shop last week with nistune and it feels like it pulled from 4500-7000 very good on 19psi. Butt dyno was reading 450-475whp.

Its a give and take but I'd stick with the HY35/HE351 setup you have. It will make 400-420whp on pump gas at 18-20psi with a good tune. You will pick up 50-75whp up top with a 35R at the same boost but you will lose500rpm of spool.....

I love my T2 20G on my sr20 car. It traps 125mph in the 1/4 and hits like a louisville slugger at 4Krpm on E85 with 22° timing. Your car should be very similar to my sr20/20g car. Except you cna make the same power I am on pump gas with the 2.4L

Ok, so the s14 pickup is the more 'robust' pickup? I am swapping out an oil pan today, and figure maybe I'll change to whatever is the better pickup. thanks for any help.

I would get the thing welded 100% for peace of mind.

Looks like there's just a couple tacks on it.

The car makes 11psi by 3900 and 21psi by 4100 (3rd & 4th). There's definitely more to consider besides displacement for turbo spool. I have a fair bit of head porting, good flowing manifold, downpipe, jwt s1's & port matching to help with spool, stock intake manifold doesn't hurt as well.

As for the oil pick up I'm just going to get a brand new s14 oil pump for peace of mind. Considering Nissan had made revisions to the s13 one, I figure it's got to be the better one.

they're just tacked together with TIG, then brazed. wouldn't be a bad idea to fully reweld it and reinforce it...
