the ultimate 22re head

i'm gonna re-do my spare 22re head
has anyone tried larger than engnbldr.com o/s valves?
they are 1.2mm o/s intake and 0.9mm o/s exhaust as i remember
and am using his 'mild efi' 270 cam
i'm thinking i'll fill in the top swirl above the intake valves with epoxy, as i see this as a wasted space in the flow pattern
which would cause eddies and turbulence
which would not be helpful for performance
and then if the 'choke point' of the intake where it bends down towards the valve is not reduced down to 65% of the volume of the entry of the intake port at the manifold joint, i'll fill in the floor of the port up to the choke point till it is 65%
this is supposedly the magic number to create the best 'velocity porting'
this seems highly effective on this long stroke motor
and maybe would get rid of the flatness at the top of the powerband ?
i'd fill in the exhaust port floors too if it didn't require welding aluminum
or i could ask the dOOd who's gonna weld up the coolant port erosion how much he'd charge
it's gonna be milled .020"
that's a lot
that won't cause timing chain tensioner problems, will it?
with nitrous and as much hp and torque i can squeeze outta this baby eventually with new cam, intake manifold, throttle body and afm, and aftermarket efi system
it won't be optimized for n20, but i won't be using it that much
it's a 88 daily driver 4x truck
or can i go much larger valves without losing much down low in the revs ?

unless your in the USA attach a chain to the 22R and use it to anchor a nice hose boat on lake elidon then get a 3s-ge when you come back

totally 100% agreed. there are lots better engines you can waste the same amount of money on to gain better results

apart from the 22 being a bad place to start, theres some hell Kooky ideas in there regarding porting, swirl and flow imho

if only we could talk him into a decent motor like a 7m

there's lots of reasons to keep the stock motor
i thot about a smaller motor
but that seems foolish in a truck
and any swap is lots of work and $$$
and i can get almost 25 m/gallon now
if this is disappointing i mite try another motor
but i'm not looking for race power
it's a lifted 4x
too dangerous to race crazy style ...
not that i don't try
building the stocker is actually MUCH cheaper than a swap
i'm keeping the stock pistons
and i'm in L A
the city the angels avoid ...
no one seems to build these without buying a lce stage 5 head
but i can't get anyone to tell me about their powerband
and $1500 for a head for this motor seems absurd
i'm mostly skeptical about the swirl technology in the stock head
ever seen the intake ports?
really really weird
never seen another head like it
doubt it actually works like advertised
swirl for low rpm power, sposedly ?
but that was right wen that one motor builder exposed his swirl tech for nascar, and caused all that controversy, which motivated the toy head designers i assume
but the nascar builder didn't really get proved correct as far as i can tell
the choked down velocity port ideas came from motorcycle builders
and the stock intake has poor injector aim and design
i could maybe gain sum mileage with a homemade manifold
and power i'd expect

If you really must use a 22R, forget about using the stock head; get your hands on a 20R head (far superior) and build a hybrid like everyone else does. The 22R head is intentionally designed to be restrictive, so getting any power out of it is going to be an uphill battle.

Even with the 20r head, your not going to be excited.
Factory in the states there was a 22rte - that may be a better idea.

Hardly. Same head, just add ct20 turbo  .
Seriously though. Turboing a 22re isnt a bad way to go. The bottom end I think is fairly solid, just the head is junk. Anyway, if you do some serious researching, and take a look at bill sherwoods "why 4 valves are better than 2" writeup, you will realise what I did and go straight for 3s powah
Cheers,

Not sure what everyone is trying to compare a 22re head with... it's not designed for high-rpm performance. It's got a 5500rpm top-end. It was designed for giving good torque down low. It's like the difference between 'G' and 'F' motors, for lack of a better analogy. You hear about guys trying to use the 20R head and that just raises your rpm range and reduces your low-end torque. Where do you want power if it's a street car?
Anyway that said... I ported and polished my stock 22re head. No other mods. The difference was night and day... it is definitely worth the effort. I'll try and get you a sound bite if you want to hear it in action... don't have a 'before' to compare with however.
By comparison, I ported and polished a 5m-ge (spent triple the amount of time working it compared to my quick job on the 22re) and there was little difference, it was better but nothing to warrant all the work that went into it. The 22re head ported and polished was awesome... night and day. Never had it dynoed, can't give you any real numbers but it feels better, runs better, gets better mileage and to top it all off, it sounds super cool.

All very interesting, but this thread is over 12 months old.
