i have a 99 prelude non sh and i was wondering the difference between the h22a1 and h22a4
second question... i have a aem intake and still have $500 left to spend, any sugestions on what to do next? im thinking dc headers and cam gears or cat back exhaust... where would i see the biggest gain?
any sugestions on a good BRAND NAME cat back exhaust system if im not going to do forced or chemical induction? keeping im mind that i dont want to ****-off my neighbors everynight... any help would be alot of help

 

H22A1 has a closed deck block. H22A4 has an open deck block. H22A4 has an OBDII ECU and H22A1 is OBDI.

Don't buy a header. If you haven't done suspension yet, I'd do that, lower it and add adjustable shocks. If you want KYB AGX, I sell those. Otherwise I'd do a cat-back exhaust. If you want one that won't **** off the neighbors I'd look at the Tanabe Hyper-Medallion, Greddy SP, Apexi WS (won't gain much power at all).

 

I have a question about the H22A4 block. How do you tell the difference between the SH and base block. Do they have a different code stamped on them?

The base prelude and SH have the same exact engines.

 

so your saying the ATTS unit could bolt right up to a base block?

 

yes, but you'll need other things, like the atts ecu

With respect to the block, yes....but for whatever reason the SH cams are different. Check page 2-3 in the Helms.
