Upgrades for H22A

Cam, cam gears and port and polish with a tune will give you some good gains.

If you check prelude Australia forums, one of the members got his apexi neo tuned to have his vtec come on at 4300rpm, which he said his powerband was much more linear

However if you want a massive kick, ecu tune and bolt on mods will be fine

I found that mine kicked that little bit harder with nice flowing exhaust and intake

I would allow a bit more than $2500 if you are wanting to do head work as well

$2500 will cover I/H/E, ECU & tune

Do a final drive swap - easily fit in your budget and will make the most noticeable performance improvement short of a turbo.

^How much would a FD change be? This was something i was considering a while ago given how tall the H22 FD is

Options are limited - MFactory have 4.6 and 5.2 FD up from 4.2 standard. Either would work nicely but if you're gonna do it... I'd go 5.2. Prices are on their website, I'd imagine about $800-$1000 delivered depending on which option you go for, talk to the forum sponsor I guess. I rebuild these boxes with all bearings and seals (genuine) for $950. Could be less if you just do a dodgy swap without checking everything else out, cleaning etc.

i can source a 4.54 for you. even a 5.15 but that would be rediculous
