ive done it for my 22r short block with a 500cfm holley on a 4 barrel offenhauser intake had to buy an adapter to fit it in and my head had stainless steel valves stage 3 dual springs put in valve guides and all .310 outlaw cam And a headman short stack header .the only biggest problem was my dad sold the truck to some guy before i got back from a vacation to even run the truck, i was very dissapointed but i got over it and bought a 91 rg cab pickup with a 22re . I was just wondering porting out intake and exhaust with stock guts and cam would do any difference to a 22re ?? Grew up on carby so could someone school me on efi ??
Not an expert but I think one of the many obstacles with the efi is how limited u are with the tuning parameters. Obviously a stand alone system will overcome that but I'd assume the gain wouldn't b worth the cost. I've been wanting to build up an re for the longest time. I'd definitely b interested if u do try it.
Here's the thing.... (I think.) Porting the head will work with the factory EFI. There really isn't a way to flow more air that it can feed fuel to. You don't need to change the AFR's to allow more airflow, so the stock system shouldn't have any issues until you flow more air than it can meter fuel for. The question is, how will you figure out how to port the head? How do you determine where the water and oil passages are so as to not scrap the whole thing? I'd like to know for my project too.
Ok well where im from toyota and nissan are rivalry . Everyone here knows the basic bolt on lce stuff blah blah but i noticed not much people where im from know about porting out the head .the way i ported my head is gasket match.i took a sharpie put the gasket on and marked where i saw space .from there i used a carbide bit(spelling may be wrong) dremel and some sand paper to smooth the heck out of the exhaust side . I never tried it on my re but i sure as hell know on a carby it would do miracles . So what i was thinking was to gasket match and port intake and exhaust then just match everything up header, muffler then port out the intake on the re and big bore thottle body cold air intake .wouldnt that sound like a big gain in power there? I get the most part but i dont think i mentioned im not much of a wire guy . So idk about the computer box . Will it change by itself ? Knowing it has more flow more air rammed in and smoother exhaust ? Will the computer go haywire cos its not oem spec reading ? Thats my main question i guess after the porting bs
About the rivalry aha did explain myself . This 85 nissan 720 napz with 48 weber sidedrafts passed my ass on the highway and im in a stock 22re slamming gears on 17" rims .i think you guys know how that looks right .SLOWWW!!! And weak . I just want a few stuff to do diy type so itll have more gains when i do add on the bolt on stuff.does anyone understand me here ?
Honestly, a simple gasket match and casting cleanup doesn't net much power. I've done it twice. More material would have to be removed in the proper places to see much improvement.

That is an excellent write up. I've spoken to him quite a few times over the course of my builds, and can always glean a few tidbits of new information.
Its cool.ill find something .by any chance any of you guys tried putting nissan dual valve springs on a 22r??
Youll have to check and see if the dimensions are the same as a 22r valve spring.. I used some aftermarket SBC valve springs on mine that had the specs we needed, and ordered them for like $50.. well worth the price and they fit 22r heads with no modificatiin.
Have you considered a NOS system? With the bottle heater, you can really fly with the pedal to the metal.
I have the whole hookup for the nos but i dont want to fry my rings im considering for my re to do a full blown head and stock bottom end or at least a stage 3 head with my 310 outlaw from my carbed 22r
Why waste money on the top end if your not gonna touch the bottom end? I'd atleast do some high comp pistons..
Simple . Dont got the money for that ,low budget . I have spare parts like valves,dual springs ,dual row timing,dual sprocket, oil pump n all .have a spare head to take to a machine shop n have then shave it down and do the valves probably affortable price n do the gasket matching portings myself . Intake and exhaust . Bolt on and blah blah blah. But as of right now my bottom end stays stock , maybe notch then to clear the lift of the cam but thats about it . In the long run yes i might save up for pistons . I have a stage 5 20rhead with forged 12:1 pistons on a 22r short block dual row spocket chain n all lce race header 50s weber side draft canon intake 527 cam nitrous hookup with a powerglide autotrans 456 welded diff . I get what you are saying my man but im not looking for drag racesetup .im only looking at messing around on the roads and hugging turn on my free time. Yes high comp pistons would be a great deal indeed but the head seems cheaper to mess with. Dont ya think?
