Supercharged 22r motor... need advice/HELP!
« on: Oct 05, 2019, 01:19:40 PM »
Okay, so I've got a camden supercharger 4" pulley, holley 500 bolted to a 82 22r.... motor is bored 40 over and decked, head was plained... Idk, (it was the first 4cly this shop has ever done, in 3 generaltions of owners).... its got apr studs and head gasket.

So heres where I might have really gone wrong, I bought 22ret pistons and put it in... cause I couldnt find a single difference in blocks... what ive learned is this probably lowered my compression. to much?

Idol is thing sound great... fuel pressure is an issue.. (why I had to rebuild the motor)
So I have LCE (efi to carb) regulator with a 3/8 return hose. hooked up to some deisel fuel pump thats suppose to pull 16psi...(my mechanical pump doesnt put out enough volume, I've got a efi gas tank, so tried that pump... had to drain my oil as the pressure put fuel through my WHOLE motor...)

Shouldnt I have consistant fuel pressure though? idk, so I hooked up and AF gauge to my o2 sensor... idol looks great...
timing set for a normal truck.

The Problem; truck doesnt go under load (putters out)..... is it compression or do I need to go to my 4th fuel pump?  idk what to buy at this point... is the regulator not working right?
Can I put a smaller pulley for more boost to raise compression?
do I get a 22ret head?

can anyone tell me what my compression is?

Could be anything. Sounds like a fuel issue though. Should have a consistent fuel pressure, check Holley's recs on what it should be. Check the needle valve, if it's sticking it would restrict fuel to the bowl. Try tapping the carb where the fuel feed is, it can, at times, loosen the needle valve if it's stuck. You COULD have plumbed the regulator incorrectly, possible. Carb may need cleaning/rebuild.
Compression shouldn't be too low to make power, but using the turbo pistons with the '82 head would drop compression quite low, the pistons were designed for a totally different combustion chamber.
Check your cam timing, idle can be good with a tooth out but power would suffer immensely.
As for your compression ratio? Your '82 combustion chamber would be @83cc and those pistons were designed for an 8.5-1 compression ratio with a 58cc combustion chamber. Without much more info than provided, your compression ratio may well be in the sub 7-1 range. That would be good for 20lbs of boost on pump gas.
Just a few things to check.
Sure it'll fit........ Just needs a little brute finesse.

Emphatically.... NO.  :shake:


When I read these posts I have mixed reactions.  :yikes:

First, I wonder “is this guy real?”…. is this a “robo-post”…you know… like fake news! :willynilly:

Did you REALLY build a blown 22R and NOT know what the specs are?  :smack:

In 3 generations, the shop has never built a 4 cylinder engine?   :dunno:

My 2nd reaction is…. Gee… I hope someone can help this guy!  :phone:  sirdeuce… he probably has some good input.

You’ve asked some good questions, but I believe there are a bunch of questions that would have to be answered to even get close to giving real answers.  :thumbs:

I agree, lotsa questions need to be answered before any concrete answers can be given. I just gave some generalization and pointed in a few directions.

Hey debunker,

Let's debunk your issues with some engine rebuild specs!! :gap:

Or.... should we just debunk your post?  :disturbed:
