highest shot on h22? tuning in todays world.

[Turbo Dave]

Thats what i figured you thought.

While lower compression ultimately means lower operating temps, the cast pistons will do you in far before any of that comes into play.

Nitrous is far more versitile than boost tho. I have seen some Mustang owners running a 12:1 CR with a dual phase system and of course race gas.

yup thats why i decided to do it. Pretty much the most cost effective way to get major hp gains on an H22.

im not looking to drop 5'gs into this motor or anything, i know of a company that does "econo ports" on heads for under 500 dollars. I dont know if they would know what they are doing though as far an n20 build. And should i be running wet or dry? obvisouly ill have a full throttle switch, and spray when i want to. My stang was either off, or always on at full throttle, this was not good if you nailed it in 1st or 2nd gear lol

i use a 75 shot but i can't break into 12's still in the low 13's with the bottle.

have you tried using some race gas and some drag raitals? i was hitting 13.5's in my h22 with f22 tranny and a 55 shot

ok heres an update. their is a local machine shop by my house, so im getting my lower and upper intake manifolds ported. I talked with MRX and another tuner and theyd be willing to tune, but i need a dual chip thingamajig from moates.

Im not sure wether to use wet or dry. I am going to still try and pull off a 100 shot as well.

I was told i shouuld be using 450 cc dsm injectors incase i need extra fuel.

ultimately, ill pull the head, replace the valves and sleeve the block. Thats when i will step up to 150 shot. I think thats where ill stop modding the H.

so back to reality, with the PNP intake's, a brilliant tune and/ or 450cc injectors, does anyone see 12's?

im still debating what type of injection too

damn this thread went back and forth and i really thought i would get my answer here .. I bought an H22 JDM with hydraulic trans "non LSD" and ECU basically the whole setup with intake manifold and exhaust manifold ect , droppin that into my car sooon , my questions is what would it need to use my Zex Dry 75 ? I mean colder plugs and what else ???

Sorrry for thread jackin man ....

you also must retard the ignition timing properly
