So I recently 4l80 swapped my ls gmt400 2 door blazer (02 5.3 with exhaust and a cam ~30k miles since I rebuilt and swapped it in), it’s now very underwhelming and I’ve always wanted to throw a PD blower on it. Ie a Magnuson or Whipple (and not that ugly side mount stuff). It’s a winter daily and part time summer vehicle in alaska, so it sees from -50 to 90 degrees. So reliability is a major factor and I figured one of these would be the best way to add some reliable power. I already own a turbo 55 pickup and a CTSV, not looking for fastest but just some more go.

However aside from a brand new $6k+ kit I can’t find anything used. I’d be happy with either a 1900 or 2300, just seems like there would be more of these for sale. Anyone have some leads on one of these, I’d even settle for a partial kit at this point.

 

They are hard to find used. Ppl like to hang on to them

prochargers are cheap tho and can be built to be snappy

 

LSA blowers are all the rage right now, one of those would so well.

 

and LSA are budget friendly as well

 

They were more budget friendly but prices have gone up a lot.

A used LSA blower is $1,500ish or more on ebay and a new ZL1 lid is $700-800 now. Add in the CSTV fuel rail, injectors, adapter plates or swap cylinder heads, intercooler, pump, wiring, map sensor, whatever else and it's over $4,000 now.

 

Yeah that’s about the price point I was figuring it would cost to do an lsa.

Someone local to me has an intercooled p1sc kit for a 88-98 chevy, I could get a bracket to mount the head unit to an LS. Just wasn’t sure if the p1sc would make decent power. I was hoping for 500 to the tire.

 

With enough boost you'll get to 450-500hp no problem. It just won't have that low end grunt because it's a procharger.

How much boost it takes can vary. What fuel you run, how much timing and how big the camshaft is.

 

I made 477 on 12lbs with a P1, through a 100% stock GMT800 exhaust

Im changing everything now. Different cam, long tubes, D1 conversion, 8 rib, overdrive lower and waste gate. I have all this done, but of course im
waiting on the 4L60 to finish dying so I can swap to a 6L80 and put it all together

P1 will get you what you want if your cam and exhaust will let it

 

My 370/whipple combo made 483 @ 8psi on a fat tune.

The difference from 8psi to 10psi was noticeable.

When I put the 2.5in pulley on it, it made just over 14psi. I ran pure Redline Water Wetter in the SC cooling system.

That thing was stupid by this point. 0 traction in the first 3 gears.

**** tends to break more with the more boost you run.

 

Pure water wetter and no water? Is that legal? DId it help much?
