Could this be avoided with an SU mount? This is a 3.5"

Oh yeah it's not the first time it cracked, it has been repaired before.

I'm glad i changed my order over from ETS to SU. I'm sorry bout your IC.

The 3.5 is known to rub and cause problems without the stiffer engine mounts. When/where did you order it? The SU web site clearly states the 3.5 will rub...

Uhh...there's got to be another problem here. I thought the MM just prevented excess rubbing w/ the 3.5" IC.
It looks like a stress fracture from heat, or from quick cooling after being hot.

Rubbing against a plastic shroud should not make it crack like that. Looking at the IC, only the bottom right (when looking at it from in front of the car) of the IC rubs. I ordered through another member from here, he told me how it cracked before but it was fixed.



The weld didn't fuse well enough, my guess is that the engine vibrations made the weld fail. I think this would have happened even if I had the SU mount.

Oh yeah I swapped the stock back on and the car feels like it gained 30 hp LOL!

No problems here, but I got the polished one, and 3.25". The SU is not even available yet...

808 -

Is the spot that cracked the spot that was repaired? Do you have one of the earlier ETS's? The welds on mine are solid, but I haven't run it a terribly long time yet. It seems this was a problem with the earlier ones...

Are you going to take it to a radiator shop?

the reason it keeps cracking is that the aluminum that ets used is to soft so it expands and contracts alot as temperatures in the core change the weld are much harder and do not expand at the same rate or volume,the expansion and contraction causes the long welds to crack, i had this exact problem and it took along time to figure out, this is one of the main reason ets started casting there end caps. they should have fessed up to the problem and replaced them. if you get it rewelded it will crack again

Well that really sucks. I guess I have a 700 dollar paper weight.

Exact same spot it broke before. I'm not sure if it's an early or late model. According to the pecuis owner, the unit was bought about a year and a half ago. The cold pipe bolts line up perfectly, I recall people using only 3 cold pipe bolts on earlier units because all four wouldn't line up.

dont feal bad, i got one too

Weird. Mine never did that one bit. 3.5" core as well.

Honestly... if it was me, I would just spend $10 to fix it with JB WELD and spray paint... smooth out those welds on both sides, and maybe mask the cooler and paint the tanks with high temp black wrinkle paint. It would never leak again.

Are you for real? Wouldn't JB weld give at the first heat cycle?

If there is a lot of heat cycling the JB weld could crack, but it is rated for 500-600F. I have used it in much hotter places with plenty of thermal cycling (eg. exhaust) and it did crack a little, but it was still strong and amazingly didn't leak.

I'm no welder (yet), but I'm surprised that cracked so badly.

The regular formula would take the heat and I think they have an industrial formula. The kwik set takes less heat...

I know of plenty of successful repairs of tractor engine blocks, etc... why not a little TMIC? Not that it would be the "right way" but if you don't know how to weld... that stuff is really strong. It might be hard to get it into the cracks though. I have used it to repair different things from fiberglass to steel, gun parts, remote control car parts, etc...

I was making no claims, and I am not selling JB WELD, hahah... I was just saying I would try it for sure if that happened to my ETS I would try to figure out a way to force it into the crack, probably just rub it in with my finger, apply it thick , smoothing out the welds, and let it cure completely for at least 2-3 days, and most importantly, paint the tanks with black wrinkle paint.

I've got the SU rear mm and the TT front mm.

I recently installed the ETS 3.5" TMIC - only 300 or so miles but I will certainly keep an eye out for this - yikes.

I can say though that the motor moves little if nothing with those mounts - the SU helped alot and then when the TT front mm went it the engine movement went from little to practically none.

Hopefully this will keep my TM from cracking like that - otherwise, FMIC here I go although I'd rather keep the TM for various reasons.

LOL mine is nicely polished, no way I'll paint those endtanks.

last i checked, this is the only TMIC available within reason (so excluding autoexe)

road rage, anywhere I can check up this prroblem has been addressed?

Mazdaboys.com is selling the Autoexe TMIC for Mazdaspeed6 for $707! I e-mailed them and they say it is a genuine new part. Any one know about this?

ets is the only other top mount out, but from what i hear auto exe is worth the extra cash


sorry you lost me, i dont understand your question

is there any other tmic's besides ETS and autoexe.

i don't follow how these are paperweights... ETS has lifetime against defects?

Well... if they're legit... new TMIC for everyone...

ets will only fix your top mount if you buy it from a licensed ditributer, i bought mine from ebay even though it was new they consitered me to be the second owner so i get no warrenty, i tryed very had to get mine fixed through ets, but they dont give a shit about their customers

Oh dang... where did these mazdaboys come from? Anyone ordered anything from them yet?

thay look shadie

no phone number, no address, when you click on company info you get nothing

i may order something cheep from them and see how it goes, also 700 is way below MAP for that topmount also they say they have things in stock that alot of companys are backordered on

Yeah, like COBB's SRI. That hasn't been officially released yet. Things on the site look very similar to one of this site's vendor's pages.

Had to be too good to be true. Tried to order it but AutoExe TMIC is backordered indefinitely. Will be 'several months' before they are able to get the product stateside. It would have been a nice addition to my Remus catback.

their website show who are authorized? for example.. rpm... su... etc

btw, to put it lightly, you get whats coming to you by buying from a place thats called mazdaboys.

Mazda Boys LLC
478 E. Altamonte Dr. Ste 108, #132
Altamonte Springs, Florida 32701

That address is for a ups store and #132 is a mailbox number if im not mistaking. It seems like this "store" is done out of someones house. Wonder who the wholesaler is?

Disgruntled SU employee?

Doesn't matter anyhow... Price is now up to $1215...
