The type SH has most of the modification problems because of it's large transmission. Running the downpipe and oil lines is why the Greddy Turbo Kit doesnt work. F-max would probably be the next best kit without making custom piping. I think it uses the Garrett T3/4 turbo, but the advantage with the F-max kit is that it comes with the intercooler. They dont do a very good job with placing the extra injectors and the piping isnt as good as Greddy but it would be less hassle and less expensive then the Greddy. The F-max kit will run you about 4000 give or take some, then installation if you need. The ATTS becomes a problem when you're making somewhere to about 250 to the wheels, then your ATTS light will come on and may not function. The tranny swap is a good idea, but will cost you. The F-max is probably the best way to go for the SH models if you've got about 4G's to drop, but it's the only way to make real power.

 

The tranny bolt patterns are different between the two, how did you manage to do this swap? I'm assuming you switched blocks as well?

 

I havent done the swap myself, I've just heard from other people that swapped out their SH trannies, so I'm not exactly sure about the bolt patterns. There are several items needed to make the swap, but I'm not sure where you can find the exact instructions to do so. I'm saving up for my turbo kit so I'm not ready to make the conversion yet, but you can still turbo charge your SH without changing trannies, you just wont be able to run big boost.

 

The amount of boost has NOTHING to due with the trans. Your ATTS may get "wigged" out by a sudden boost or too much if you're going all out. However like I said before you can just disable the ATTS if that happens.

 

So its possible to have big boost on the SH? Just gotta yank the chip huh?

 

I just wanted to confirm that Honda made two different blocks between the SH and the base model. There have been plenty of people to make the switch and the bolt patterns are the same. Why would Honda make two different blocks on the same 2.2 motor?? Have you seen the two trannies side by side?? and have you tried to do the swap yourself?? Just curious..
