My dad just bought a 98' Honda prelude and he thought it was a 97 at the time but after running the vin we found out it's a 98. The problem is that we need to get a new engine for it. I know nothing about Honda’s I own a 93' Nissan 300zx twin turbo. My question is what engines will work in this car? I've been told that the h22a will work then I’m told no that I need to use the h22a4 and then I also told that the 98's have a special engine that is crazy expensive.

I'm looking for the cheapest solution to this problem with the engine. The car will just be my dad's DD for his short drive to work.

This is all i konw about the engine and car
vin JHMBB6146WC012568 http://www.decodethis.com/Defa...12568

2.2L (132) DOHC PGM-FI 16-valve 195-HP VTEC 4-cyl aluminum engine
5-speed manual transmission w/starter interlock

please help

I'll go ahead and tell you that is BS.

To simplify it all for you, the 5th generation Preludes (97-01) all came with the same engine = H22A4

The 4th generation Prelude also came with an H22, but there were options for H23s and F22s. Any of which will bolt into your car, but will need work to get them to run.

All cars 96 and up are called OBD2, so with your OBD2 engine and computer you will need another 96+ engine unless you want to get another ECU or do a conversion.

Another point, the 5G Preludes were either 'Base' or 'SH'. The engines are basically the same except the SH engine block has a different casting to allow a special unit to bolt up to it (ATTS)

I would just look for any 97+ H22 non-SH block and you should be fine. JDM (Japanese Domestic Market) engines are good and relatively cheap

If he has the current engine already, he can just use bits off of it to change over and older engine to OBD2.

If it's a 98 Base any H22 will work. If its a 98 SH and you want to leave it stock with ATTS you need an ATTS block and ATTS transmission.

 

what is needed to switch a obd1 to a obd2?

edit: not to suggest that there is anything wrong with OBD2 motors. They're newer and on average probably in better shape. But if the JDM engine importer of the day sends you an OBD1 motor you wouldn't necessarily be SOL. Depending on what you have on hand, anyway.

thanks for the help. this can't be any harder then doing a 300zx na to tt swap.

 

umm yuh huh yes it can.

 

i dont know vs. maybe its' a draw

 

FYI, I believe there are actually some small differences between the '97 & '98 H22a4's dealing with mostly emissions related components and how they are wired. I believe if you get a donor motor from a '97 you will also need the ECU from the '97 and some of the engine wiring will be a little different. Just a heads up that it may not be a straight swap. Not that it matters a lot, but '99-'01 also is tuned for 10:1 CR whereas '98 is 9.5:1.

 

What's wrong with the engine in it?

 

timing belt broke

Another option would be getting a head for it. As far as engines, basically just find out if its a prelude SH or base. If you want it to be as simple as possible, get yourself a obd2 engine (base or SH depending on what you have) and call it a day.

Obd1 to Obd2 wouldn't be "that" bad, since you already have the old engine (obd2). Swap distributor, injectors/intake manifold and the oil pump with the crank sensor. Again, that would be if you don't have a SH model.

Personally, my timing tensioner went and I bent some valves. Took the head to the machine shop, had the valves + selas replaced put everything back on with new gaskets/seals. Head's like new, but it depends on if you feel comfortable pulling the head and timing it. hth.
