I got a 99 civic coupe and im planning on getting my complete JDM ITR swap at http://www.hmotorsonline.com/shop/ now i got a few question for you honda enthusiast.Im pretty sure a lot of newbie like me here wanna know this too.
i've seen a couple of site online that has this kind of swap write up before but all of them is USDM ITR so im not sure if they are the same JDM.
1.what do i need to get before i swap the engne? for instance mounts,brackets and etc?
2.is there any modification to the catalytic converter? if there is any modification to the cat i just want to know if there is any after market cat that i can purchase that is made for swaps from D to b series engines.
3.do i need to get new spark plugs,spark plug wires & distributor cap?
4.do i need to play w/ the ECU like wiring and all that or do i just have plug and play whatever came w/ the motor package?
5.i realize that the JDM type r integra go more compression than the usdm.now i just want to know if i need to get a higher octane gas b4 the swap?
6.do i get a lot girls for doin this swap?(dont mind this last question)

 

I see that you're new here. The answers to these questions have been discussed numerous times, but I'm in a good mood so here goes:

1. Hmotors is good about including everything necessary to get the motor in the car and running, however for your particular application you will need mounts and brackets for a 99-00 Si.

2. You will need a larger cat as the ITR motor uses a larger exhaust collector and won't bolt to a stock D series cat. Carsound makes a decent aftermarket cat that should work well for you, but also consider upgrading the exhaust if you haven't already as the stock exhaust is particularly restrictive

3. It won't hurt to change them, but I didn't have to on any of the swaps I've gotten from Steve.

4. Regardin the ECU end of it all, if your car is an EX model, then no it's just a plug and play operation, if it's not an EX then there will be a few easy wiring tasks to deal with. Plan on buying an OBD-2B to OBD-2A conversion harness though. Regarding the engine end of it all, you'll need to modify your stock harness to work with the ITR motor. This simply involves the extension and relocation of a handfull of plugs and can be done by anyone comfortable with a soldering iron. Your other option is to find an engine harness from a 99-00 Si and use it, but modifying your stock harness is a hell of a lot cheaper.

5. Run premium, it shouldn't ping. If it does ping, then retard the dizzy just a tad or run some octane booster.

6. They'll all probably think your crazy for spending $5k on a motor and leave you in search of more practical men.

aint that the truth. Ask my ex-girlfriend
You may want to consider some motor mount inserts or upgraded mounts. They will tighten everything up a bit on acceleration. Yet, you may not like the vibration you will get from them. I suppose its all preference

 

I've been reading about the axles at this board that the jdm itr got 36mm axles and the usdm got 32mm.will JDM itr axles fit my 99 civic ex?

ill accept a yes or no answer

 

No JDM itr axles will not fit your 99 Civic. You have a couple of options.

1. Hopfully http://www.hmotorsonline.com/shop/ sent you USDM B series axles.

2. Buy new axles,

3. Buy JDM ITR 5 lug conversion. axles would fit right in.

Good Luck

 

can i use my old axle(99 civic ex)?if not ,from what car i can use,like what are my options?

 

Sorry your D series axles on your 99 ex will not fit, you will need B series axles.

99-00 Civic Si would be an option,
94-00 Integra w/o ABS would be another option. Its just up to you...

You could try selling your JDM ITR axles online, I know there's plenty of people out there trying to buy 36mm axles.

 

i have the top tranny mount off my CTR motor if you need it, i'll sell it to you dirt cheap since i have no use for it
