how do i install mckinney motor mounts

[s13convertiblerb]

i have an s13 convertible, and im installing a RB20det. i dont c how the mckinney motor mounts fit in...does any1 have a pic? do these go on the original motor mounts? also since i have an rb20det i can still use the stock driveshaft right? Thats what i was told, is this true?

[BoostFab]

your 1st post and i will assume that you didn't do your search. read the *sticky* at the top of the forum....

Doesn't mckinney give you an install guide as well?

[s13convertiblerb]

I did a search but found nothing on the RB20det mounts. Mckinney didn't give me a guide or anything when I bought them. It looks like I have to drill through the crossmember which doesn't make any sense to me. Did they give me the wrong mounts? Please help!!! Thanks.

[modestmouse]

Why don't you call them? Im sure they meant to give some sort of instructions.

You need direction for this?

[NightKids2]

Mine did come with directions, and while Ill admit they arent as clear as they could be... you still could figure this out. You need to take off the motor mounts that are already on the car. Mckinneys mounts only go on one way, if you cant see how they go in try putting them on your RB while its out of the car. They leave one hole for your to drill through the cross member.

Correct you do have to drill through your crossmember... I know those instructions are a little difficult to understand... but just look at the pictures and compare to your motor/crossmember... after a little time and experimenting it should become clear there is only ONE way these mounts bolt up.

call me @ 951-304-9300 Mack @Mckinney

Mack is such a nice guy!

Hey S13convertiblerb... It's cool to see another RB20 convertible in the works. Hope the swap goes well for you. Remember to wire it so that the car thinks it's in park at all times... that way you can use the top.

Check out the convertible forum on this site as well. Lot's of good stuff.

Post some pics when you get the chance.

why do u have to drill through the cross member?

[420_240]

Apart from the side that actually bolts through the crossmember where the block adaptor plates went... there is a plate that protrudes from Mckinney mounts that is perpendicular to the block adaptor surface of the crossmember... (if you were facing the front of your car and looking underneath it... you would see this side of the crossmember).... this "plate" has a hole predrilled so you can tap your crossmember for added support...tell me if the message isn't getting across clearly

[OKCA18DET]

well im sayin if i pay 400 for some mount kit and i bolt the mounts to the motor and cross member i wouldn't wanna do any other work other then bolting in on..anywho is it a MUST that u drill through the cross member?

[420_240]

It's not neccessary... but you have to take into mind that the crossmember required to use these mounts (240sx xmember) was not designed to support any RB motor... the holes are conveniently predrilled through the mounts for your pleasure. So stop being a lazy *** and tap through your crossmember... i mean if it's that hard to drill 2 holes ... then i don't reccommend this swap.Like i said before, they are there for aditional support

[modestmouse]

Hey, buddy...drilling those two holes couldn't take more than five minutes if you're slow as hell.

my thought exactly.

[NightKids2]

I believe it says they do that because each one is different and you drill the hole yourself to get the best line up. Or maybe they do it because there just isnt a hole there lol. Either way, if you dont do it your mounts will probably fail. If you think its more work to drill a hole than to swap in an entire cross member and bend all your PSlines and have your motor sit high and forward, then dont buy the mounts.

[OKCA18DET]

all i want for this question is a YES or NO1.after drilling these 2 holes then do i put a bolt through it with a nut on the other end?

2.i can use new ka24e motor mounts with the mckinney mount kit?

3.after buying the mckinney mounts i will have no problem using the stock 1990 240sx drive shaft

4.Thanks

[BoostFab]

1) yes2) no--they provide the mount(spacer) for their adapter kit.3) rb20det---use s13 driveshaft ok. rb25det use custome driveshfat, or theirs.

[s13convertiblerb]

YES you do have to drill through the crossmember. I have the mckinney mounts attached to the motor and its sitting on the crossmember right now. This way I know exactly where to drill through. The mounts are adjustable and slide back and forth and that is what the other bolt is for. It is to secure the motor in place once you have it where you want it. Email me for pics. I will let you know how it goes.

OK once again with "SEARCH" ok now to anser.

1. you are replacing the engine with one MUCH larger and MUCH more powerful. It is there for the extra strength. I'm sure if you are to lazy you can unbolt your crossmember send it MCkinney and they would drill it for you. *the bolts are included you just need a bit and a drill*

2. How could you think of using KA24 engine mounts in conjuction with the rb25det engine mounts you bought. get it rb25det engine mounts as in this is what you use.

3. the Drive shaft cannot work. you could pay $50000 for mounts or for someone to install you engine a custom driveshaft is needed no matter where the engine is. the yoke needed for an rb25 is different than that on the 240sx. z32 N/A yoke.

4. solution buy a honda.

[OKCA18DET]

RB25? who said anything about that?i was asking for the RB20 but i assume its all the same when it comes to mounting everything minus the fact that the mounts are differentand dont be a d!ck cuz the favorite "search" button at the top that everyone says use doesn't answer my questions

[Miata Master]

I apologize.I totally missed rb20 I have been working to find info on my 25 so I messed up.the Driveshaft has the same yoke as for the ka24 and as long as you have a manual already i am 75% sure you can re use the stock driveshaft.

Sorry again. I feel like a stooge

[b-s14]

sorry for reviving an old thread, but i had a question, is it ok for the motor to sit in the bay with the mounts and the cross member not drilled yet... (not that i am going to leave it like that, but i need to go find the bit to drill through the crossmember) just wonderin if it is ok to sit for maybe.. ? a day. .?

[OKCA18DET]

well from what everyone says the "drilling" is for extra support, so yes it is safe for the motor to SIT in the bay

[b-s14]

one more question, on s14, when the mounts are bolted down, are the bolts suppose to angle a bit due to the s14 x-member.. ?
