anyone ever supercharge an h22a7
long time lurker first time poster...
for the last three years i have been driving an accord type R (98-02)...... it runs a h22a7, 220hp standard.....
i know a few people custom fit the a7 (also available in the accord euroo R 99-02) into other chassis etc,
i was just wondering has onyone SC the a7, as i have just recently purchased another accord type R for track and reckon a s\c would be a nice addition.......
here's a pic of my car, i'm sure people on here know it

There is a S/C for sale for the H22 Prelude. It's a Jackson Racing S/C.

I have seen one on an Accord previously. It required a bit of fabrication to the fire wall. That is with a N/A CB7, CD5 chassis. i'm not sure if the Euro R has a longer engine bay or not. As well there is a bit of fabrication needed for the belt and pulley bracket to fit between teh engine and the drivers side (LHD)/passenger side (RHD) strut tower. from what I remember seeing.
I thought about doing this same mod but ended up going a different direction. I may still end up going forced induction after a few yeras running my current build. It will be FI but it won't be S/C'd though
Nice Type-R

CH1 is the same deal as the CB7 and CD5/7. You are goign to have to hammer in the fire wall a few inches and cut the right strut tower back. In order to fit a Jackson S/C in that bay. I think a roots style S/C or a turbo setup would be much easier.
thanks
I'm a N/A fan myself. The only way I will go turbo is if I can custom make a boost setup to work with my ITB's. That won't be for quite a few years though.
Good luck with the research

Wow, I love the ATR. Looks real sharp. Wish I can cruise in one of those over here in the U.S. People would go nutz seeing one cruising down the road.
Kinda seems odd. You want forced induction but don't want forced induction? The supercharger and turbo will both put more strain on your motor. So long as you take the precautionary steps (building up the motor) prior to turbo'ing you can get decent power from it even at lower boost on a larger turbo or higher boost on a smaller turbo.
That is correct, would you care to state why? Rather than just say it won't fit.
If you were to end up going with the JR S/C you would need to buy the bottom half of a dual runner H22/23 manifold. The Euro R is a single runner one piece manifold whereas the USDM H22A1 is a dual runner 2 piece manifold.

i think the reason the h22a7 has issues with turboing, is the compression ratio of 11.00:1
i'll go have a look now... thanks for your input
as below you will see i never said i didn't want to go F\I, just not going to put a turbo on it, i don't want the hassle as the bottom end would need changing.....

Especially since those Rotrex kits are ~$4000-7000 depending on application. The supercharger alone is $2600.

No, I realize that, the way I worded it was you want forced induction (super charger) but don't want forced induction (turbo). If you're going to put in the amount of money for a supercharger and tuning and all that I'm sure you could equally price out sleeving the motor and all that.
plus turbo also would involve me wasting a brand new custom hytech header which i have ready to go on lol
nice car by the way, very clean engine

think i'll go with modifying the firewall and fitting a JRSC......... seems like a decent option, i have found a mini cooper s supercharger for a ridiculous price, but think it spins the wrong way ;(
