I've got a couple questions before doing an engine swap. My 98 base 'Lude is getting up there in the mileage dept. and I'm seriously considering a JDM engine as a replacement. I've got 278,000 miles and she still looks great and runs good, but it's just a matter of time.... I'm burning a quart of oil every 500 miles or so and she's lost a little power.
I'm considering buying from JSA Motors. Anyone have any experience with this co.? If I'm not mistaken the stock (base model) engine in my 98 'lude is an H22A-4. Correct? Would the JDM S version (220 HP) drop right into my car? Should I go for that or the JDM H22A (200 HP)? Will I really notice 10% more HP? What did Honda do to the engine to get it up to 220HP and the compression up to 11:1?
Thanks in advance for any info. Martin
it might be cheaper to just freshen up your existing motor, rather than buy another used engine....
This is only true if you can build an engine by yourself, and have the facility to do so. If you have never done it before, I highly reccomend not doing it (for your daily driver). If you have to pay labor, it is definitely more expensive to rebuild a motor, rather than buy a new shortblock.

Yes, your stock block is the H22A-4

Both will drop in without issue (as far as fitment goes). To run the JDM H22A You will need to use your stock wiring harness and ECU. Also, you will need to swap over your H22A-4 oil pump w/ crank position and TDC sensors (not hard at all). As well, you will need to run your H22A-4 distributor (again, not hard at all). You will need to use the injectors from your H22A-4 also. The JDM type S engine might require a different ECU, I can't say for sure.

You will certainly notice the power increase from either of the motors you could swap in. I would say that the 20hp between the JDM and JDM type S motors is certainly going to be noticeable though.
The extra 20hp came from camshafts that have .5mm extra lift (am I right? check the NA archives for more info on the type S stuff) and re-designed pistons, IIRC.
If you do this, there is no need to buy a complete longblock. All you need is the shortblock, which should be cheaper anyways. You can re-use your head and all attached components (which I recommend for simplicity anyways).

The head was also P&P, different air intake system, etc
The S Spec was just like the Type S, but has no ATTS and an LSD. So many of the "type s" engines sold are in fact "s spec" if they have the block like a base model.
I did a H22A JDM swap into my SH and it was well worth the money spent IMHO. A few pieces of advice, make sure you have a competent shop to do the swap before you even consider doing it. I personally disagree on the ease and price of doing a short block swap, 99% of the places that import motors sell them as complete long blocks.
Plan on swapping all the OBD-II equipement from your existing motor to the new motor and you should be fine. From what I've seen regarding prices of the Type-S and Si-R it makes more sense to just go wtih the H22a and then use the extra money for some nice bolt ons or perhaps cams.
Do a search theres a very comprehensive thread regarding what needs to be swapped from one motor to the other and a rough idea on costs.

I have a question, i was told in order to have the jdm h22a types, you had to have a bb6 type s model for the atts unit correct me if im wrong?
i too also have a base model and when i bought it i was told it had a type s engine in it, and after researching i sadly dont. Would i happen to have just the jdm h22a engine??
In order to tell what you have, you need to look at the stamp on the front of the block.
If you want to convert your drivetrain to ATTS, it can be done on a base. You will need SH axles and LCAs and a few other suspension bits as well, but it's doable. Also you will need an ATTS ECU.

i have just gotten my car back from the shop. they swapped in the type s engine into my base auto prelude. i still have the automatic gauge cluster and i notice that the srs light is on and also the battery light and parking brake light is dim when not engaged and when i engage the ebrake the battery light goes off and the ebrake light goes bright as normal. do i need the manual gauge cluster to fix these problems? oh also it shows on the auto cluster that i am in "gear 2". how do i get rid of that? other then that it runs beautiful. it was definitly worth while.
i'm using the ecu that came with the engine. i'll try reseting the srs light and such today cause i found a couple writups here that show you how to. (dont know why i didnt do that earlier.) but the "gear 2" light is kinda buggin me. anyways i'll post some pics up today of my cluster to give you guys the basic idea what i'm talking about. thanks,
