IS THIS POSSIBLE?

i have alot of experience with hondas but recently invested in a type sh prelude.
im wanting to get rid of the atts unit and swap the motor to f20b or even just a h22a1.
i called jdm engine corps. here in richardson tx and the guy over the phone was telling me i have to use the a4 motor or the type s motor saying it has to be an atts motor???

is this true?

 

What is your goal? Why do you wish to destroy an SH? Wouldn't it be easier to simply sell it and buy a base?

The F20B would be a bad choice for an already fat ride.

 

It's pretty straightforward. Base engine/trans/intermediate shaft/axles, that should be it.

 

Type-S engine stamp is just H22A and came with the atts trans. H22A1 is a 4g engine. A base H22A4 engine will not mate to the atts trans.

Why buy a SH if you didnt want the atts to begin with?

 

X2

 

just did this.

if u get n e thing OTHER than an SH engine...ull need a tranny and axles to match.

thats it, dont make it difficult by askin more questions on it.

u keep ur ecu, but atts light will be on, it wont affect HP.

 

ok so i can buy any h22a swap and it will fit in this chassis?
just like any b series will a civic?

i bought this car for 900. it had electrical problems which i fixed. now as i was looking at the under carriage and noticed that the rear t bracket bolts that go through the trans casing have came loose and busted the trans casing all up. so instead of trying to find a GOOD sh tranny i would rather spend a little extra and get a more powerful motor with alot less miles.
i dont give a **** about the atts unit. in all honestly its all up in my way. im not a twisty turn kinda guy. yeah it handles great but i would much rather have a car easier to work on.

 

I guess in your case, it kinda makes sense.

 

I don't see why it won't work by just dropping in a complete JDM H22A or an H22A1. The wiring should be the same except you might have some leftover plugs that the H22 don't have from the SH motor.

 

Really? With either of those choices, you have the OBDII -> OBDI conversion (sorta with the JDM), then you have to address the axle/halfshaft.

That's not exactly PnP.

 

It's as PnP as any other H22 swap in a 5g (except for an actual A4->A4 swap). You just need to take the axles out of the knuckle as well.

 

not quite sure i understand you by the "axles needing to come out of the knuckle"?

if i buy a jdm non atts h22 swap it should come with the intermediate shaft so thats where lies my question!??! will BASE model axles complete my swap? and will the motor sit in the chassis correctly?

this is my first time messing with a type sh chassis..

PICS ADDED

 

For the lazy one can normally leave the axles in the knuckle, and just pull them out of the trans. But since you need to change them....

It should usually come with the intermediate shaft and bracket. But they can often be pretty rough shape. And yeah, you'll need base axles. And you're good to go.

 

oh ok.

well when i swap motors the axles are the first thing to come out.

thanks for the info bud!

 

For simplicity, keep it OBDII as the year chasis IMO. Yes, you'll need the axle & intermediate shaft for the base engine; since, you can't use the Type SH axle.

My buddy has a SH model Prelude. He went from SH to a blue top JDM H23A VTEC set up and has no problem whatsoever dropping it in and getting it running. People just making it sound harder than it really is; thats my thought.

 

omg...


jesus...


buy an ENGINE.

buy a TRANNY

buy the corresponding AXLES


and SWAP.



WHILE YOU ARE AT IT...

get new oil pump

get new water pump..

change timing belt of new engine...

and convert from automatic tensioner to manual.


seriously, there shouldnt be another post after this one...really..

 

go away

 

I have a similar situation that i just encountered today. Have a customer drop off a base model prelude that has a hydro locked base h22 in it. The motor he brought with it is a sh h22 with the atts bullshit on it. So my situation is opposite as this one. Will it work can i put the sh motor and trans swap in the base prelude???? Or am i going to have a bunch of problems?? I'm not a prelude genius so i thought i ask you guys.

 

It's going to be a bit of a mess. You could use the SH block, a regular transmission of some sort, and the adapter plate (PirateMcFred has posted pictures of that) that is used to bolt the base intermediate shaft to the engine block. Putting the whole assembly in would be pretty silly, the ATTS unit would just be a brick.

 

I was planning on using the entire swap out of the sh prelude with the atts trans. I would not be using the stock base model h22 trans. I would be pulling out the hydro locked swap motor and trans and then putting in the atts swap motor and trans. Just wondering if i would run into any probs? Thanks for the suggestions. Just wondering if its worth my time or should i tell dude to pickup his stuff?
