DIY | CIVIC SI TRANS IN A RSX! 

Bro!!! I bought a 03 type-s the other day been losing my mind why the gear shifting was backwards! Couldn't find anything online about it. Found out the transmission was from 2010 civic si and yeh man saw your video have to switch out the gear selector component and fix the speedometer because it doesn't move. Dang bro I owe you a beer or something doggy!

Do you know if the LSD out of the SI transmission will fit in the TSX 6 speed?

I’d assume you would of swap counter shaft gear stacks as well as add the VSS ring gear to the Si diff trans and open the Type S and swap counter shaft with Open diff. Seeing the gearings the same

Nice video! However, that speed sensor needs to fit tightly and the hole must be perfectly round and machined smooth like OEM. Otherwise the sensor gear may not make good contact and the O ring around the sensor won't seal, allowing dirt and water to enter the transmission and possibly oil to splash out. That's one of the few things that is IMO worth paying a machinist a few bucks to do for you unless you have the proper equipment to do it right. Other than that great job though!

CESAR Whats the sensor by the shifter mechanism called ? I broke mine!

dope video bro thanks for the content i appreciate ya 🤜🏽🤛🏽💯🔥

My case is not closing???

I bought a Type-R LSD but this was back in like 2008 or 9 when the Civic Si wasn't out for long.

The 05 06 rsx doesnt require the drilling for speedo . k20z3 and k20z1 is the same plug sensor

God job bro, video was very informative. Thanks for sharing.

At least this vid actually shows the work, unlike that other guy's vids that shows before and after shots. I presume that knowing how to do this took some research to figure out the parts swap. So, thanks for that. Doesn't the SI use a Torsen LSD?

How do you remove that speed gear?

I got si nhr3 and k20a3 from rsx. Putting in 86 crx. I just did the clutch and when trying to bolt the engine to transmission, found top 3 bolts are different. Left corner lines up, but other 2 seem off.

What size tap for the shift selector and for the speed sensor

Only 06-11 civic si transmissions work ? Looking to throw one in my 06 Type S

Do you use the si axles or type s or are they the same ??

Can anyone tell me which intermediate shaft do I need? Civic Si or RSX Type s

did are you swapping whole case? instead of lsd into a2 trans

Do anyone happen to know what transmissions aside from the NRH3 will directly fit the 02 ep3 si K20a3 with little to zero modifications ? Just killed my transmission and need an equivalent replacement .

Will I need to do this even with a k24a block

U think it safe to run 2 bolt instead of drilling and tap?

does the transmission use the same mounts?

Is taking apart the transmission necessary if I have Kpro? I believe Kpro can correct the VSS for 02-04 RSX type s but I’m not sure.

Will this work for a base model

How the lsd is holding?

What axles did you use?

Did u have trouble with your vss not making contact when everything was put back together?

Do u have to swap ring speedo gear onto si lsd
