Been a member on this site since 03' and now i'm finally seeking some resourceful advice.

My 97 SH finally went out at 283k miles. I decided to go with a H22a Euro R with LSD tranny.

From my understanding and research, I can keep everything the way I received the swap without much modification.

This is what my friend is doing on my swap:

EGR blocked off
JDM distributor and modify internals
Swapping IACV valve from USDM to JDM with an adapter from Rosko Racing.
Using AEM fuel rail with adapter from Rosko
Running p28 with Hondata
Changing all seals and gaskets, water pump, timing belt etc.

I am trying to make sure this goes as smoothly as possible. Any advice from anyone else that has done this swap?

Thanks in advance everyone!

 

ATTS doesn't work with an OBD-1 ECU conversion with or without Hondata. The car will drive... but no LSD anymore. So, you will get a well tuned engine with the extra weight of the ATTS system and a base "one tire fire" transmission.

 

it has mechanical LSD.....

 

I understand that, but I bought the complete changeover. I am removing my ATTS tranny and SH motor for the Euro R and LSD tranny.

LSD and ATTS are completely different.

 

I think you have your bases fairly well covered. Might want to think about a new clutch while you have it out of the car, and good time to do the rear main as well.

 

My apologies OP... I misunderstood what you were swapping in. I think you have a good plan.

 

+1

and manual timing tensioner swap

 

Ah yes, that as well!

 

No worries at all

 

I'd love to see some pictures of this. I've been on here since '04 and had a '99 SH back in 2001. This makes me want to get another Prelude and do it up right.

 

I will post pictures once completed. We are a month in a week in and almost complete. It has taken longer than I expected, but things always come up and never go smoothly. I'm hoping by this week.
