rb26dett s13 mckinney downpipe issues?

[240z!!!]

well i bought my mckinney dp a while ago from raw brokerage and when it got to me i made a test fit everything looked alright aside from the very rough edge inside the flange for the front turbo that i finally got around to grinding away, after wrapping it with header wrap and coating it with the silicone spray, i finally got to the point where i could mount the motor in the car, after everything was mounted i had issues with the dp not fitting what so ever, i finally figured out a mounting solution so it fits, my two questions are 1. the dp clears but i have to take my steering knuckle apart to get the dp in there has anyone else experienced this issue? 2. after fitting it i realized that the dp will not fit without either modifying the dp in some way or hammering my floor pan in as it sits to high, the only problem is that my motor cannot be mounted any lower or it will be laying on the crossmember and i dont want to hammer my floorpan in as it will make a lump under my gas petal and i will be highly disappointed if i have to modify a $515 downpipe that ive spent over an hour grinding rough edges smooth and almost $100 wrapping it, i bought it so i wouldnt have to worry about this issue but i guess i was wrong, does anyone have any first hand experience with this,

oh its a 93 240sx with a completely stock rb26dett

thanks

Are you using McKinney mounts or custom mounts? Try PMing fast-datsun on here.. he's with McKinney

[240z!!!]

custom but basically replica's of mckinneys design but motor is as low as possible and cannot go any lower i even tried resting the motor (with no mounts suspended by the hoist) on the crossmember cant go any lower unless the cross member itself is lowered and still wont clear the floorpan, im using a modified rb25 oil pan and the car previously had a rb25 in it using same setup,

on second thought i guess it would be a mckinney question but they make a 240z dp also wonder if i got sent the wrong one....

[240z!!!]

i actually called mckinney and they gave me some great advice on degree of the motors angle gotta check a few things and may have it resolved

sound like the ""COPIES OF OUR MOUNTS'' are not very close copies. send pictures of the other problems and I will address them. As for fitment How do I address that as I can not speak to your illegal copies on how they we made and how close a copy they are??????????????????????????????????????????

putting patents on things now-a-days is damn near useless as there are sooo many ways around it. All they have to do is change a few things and BAM..a totally different product according to the patent office.

Your right......... Hope he get the car fixed....

i had to remove the steering joint everytime i had to remove or install my rb26dett mckinney downpipe. theres no way around it, but i would just buy the real ones from mack if you want the proper fitment.

But here is the funniest thing about this thread. It is like buying a fake Rolex watch. Then when it breaks or doesn't work, complaining openly on the internet about the problem and blaming Rolex, getting Rolex involved, then saying "Oh BTW, it is a copy." I mean, come on people. If you have a copied product, and have purchased something meant for an original product, then when it doesn't work/fit, why are you complaining? Look in the mirror and concentrate hard, that is the problem and the solution all in one.......Ok, I am done venting, sorry.......

[Ramius83]

And on a side note, I take it that the front turbo pipe is the thing preventing a full install without removing the steering column. Well, do what I had done. Hack the down-pipe immediately after it clears the steering column. Then install/weld a flange on both sides. Then when you need to remove the down pipe or engine, the piece that goes to the front turbo outlet stays on the turbo, and the rest of the down-pipe can be removed without dropping the steering column.

When I installed my rb26 into my s14, the mckinney mounts and DP were not a true bolt- on affair. The mounts actually had the engine too low (but then again im using rb26 cast alum. oil pan). I had to put one inch worth of washers on the driver side mount and half an inch on the passenger side so the pan would not hit the cross member. For the mckinney dp, you have to take out the metal oil return tube and totally cut and re-weld it so it doesn't hit the downpipe. I also had to bend alot of the turbo oil/water lines as well as the hard line located on power steering linkage. Just made sure the line didn't kink but it was close....very close. I did call Mack a few times and his tips helped immensely. It is a well made product, but what do you expect when you install an engine not meant for this type of chassis.

I actually had the old isolators because i bought these mounts years ago but never used them until recently. HIs customer service is top-notch. Called him and he sent me the new versions out ASAP for free. Can't beat that.

Yes the mount were designed for the rb25 oil pan, if you use the 26 oil pan you have to raise the motor. You always have to disconnect the steering shaft to install the down pipe as it really tight......... You may have to move some oil/water lines also....

i paid good money for my mckinney mounts and i am completely satisified. was pricey but i have not had to look at my mounts since i bought them

I have also had some issues with the mckinney dp.






Stock R33 Rb26DETT with stock turbo side setup. As you can see from the pics, there was a huge gap on the second flange, that no amount of gaskets could have fixed. I ended up having to chop the downpipe and reweld it so the pipe flanges sat flush. Also both flanges were warped so they needed to be resurfaced. The downpipe also sat too close to the rear turbo oil return. I've used a mckinney dp on a previous swap years back and didn't have issues. I'm guessing they're jig maybe off.

I also had issues with they're mounting kit.





The angle of the lower engine mounts to the upper engine mounts are not the same causing the mounts to distort and bend. the motor sat very low causing clearance issues with the downpipe. I ended up having to toss a bunch of washers under the driver side mount until there were only a few threads left. Clearance issues were taken care of for the most part, but it could be better. Unfortunately in this situation it seems the problem is not in the jig, but in the actual design of the mount kit.

i consider mckinney stuff to be average quality, there stuff might not be well designed but it gets the job done for the most part. Fortunately for them, they don't have much competition in these niche markets so they're stuff doesn't have to be top notch, and they can charger whatever they want.

We can not address problems that were not broght to our attention. WE will work to make correction when we know what there are. there are problem caused by just being 15 year old car, and many we correct when we can. on the TT down pipe its the same jig we used since 1998.I will look at the fit up.... Please forward all problems and complaints to us so we can address them... Mack

Send me your address I will send you new red issolators and Please send the old ones back to me for testing... we are looking at the RB26 mounting kit design and build procedures...

I'm using the entire front R32 crossmember along with it's normal factory mounts in my AWD S13 240 coupe.

Doing an initial fit up of my downpipe it doesn't look like there will be many issues. As of now an original/factory downpipe just travels to far downward and winds up a bit below the unibody frame rail, but that won't take much to fix. Just a couple cuts and a little angle change here and there to shorten it up.

It is close-ish to the steering, but still about 3/4" clear. Enough for me.

I'll post pics when I get it done. Maybe make a pattern/jig so I can do duplicates.

Mckinney folks, is your 240 RB26 downpipe designed for what I'm doing or just for a RB26 in a 240 with the 240 crossmember and your mounts?

Thanks!

Just wanted to point out that you couldn't ask for more than that... well done Mack!
