I think the TID will be my next mod and while I have been reading about them, I would like to know how you guys that are using them have liked the mod? Worth it? Held up or time? Hasn't melted? ha ha
Was it somewhat easy to make/install? Any area's of concerns?
Thanks much for any imput.

I did it, I used PVC, helped a good bit, turbo spools a bit faster, aswell as a bit higher, and you can hear it spool. I used PVC, and it worked fine, not melted yet. Took about an hour to do, that and open air venting my BOV, not a hard mod at all. I definately recomend it. Costs like $10

I used ABS. Seems to work fine for me, and have had no melting problems. I cannot speak about performance since my car is not a stock TII, but I can certainly say that it will outflow the stock TID. If you use black coloured pipe, you will want to paint a light colour to minimize heat-soak.

here's my TID. made of 3 inch steel. held in place by home depot rubber connectors. i should have used automotive connectors, but i'll get them some day. it's a good gain for the money. turbo spools quicker, and sounds like a jet (a small jet). with that, a down pipe, and a FCD i can get 11psi on the stocker turbo.

Sounds good guys, anyone else?

Myself, i'll be buying a mandrel U-Bend and ARC welding it. I think that'd be a tad better than using PVC... And if it works well, i'll take it out and make a mold out of it, then bring it to a friend's manufacturing shop.

The problem with metal is that it heat soaks. That's probably why Mazda used the ABS in the first place, and that's why I used ABS. Also adds a little bit of weight....

Oh, and have fun arc welding thin-walled pipe.

Fingers

Thanks for breaking my heart again, Aaron!! Curse your secondaries!!

Seriously though, is $30 USD shipped good for a mandrel u-bend 3"?

And whats gonna happen when i try to arc weld thin walled pipe? Should i just take it to my buddy who has a mig welder, once i have the pipes cut and fitted?

Thanks yet again!

That price sounds about right if it's stainless.

Welding thin walled pipe with an arc welder is very annoying. You'll keep blowing holes through the pipe if you don't keep the current down, but this means it will be difficult to start and maintain the arc. The end result will be a mess. At least, it would be if I did it. You are probably a lot better at welding then I am.

Take it to your friend with the MIG.

Interesting stuff guys. I read awhile back a good write up making the TID, does anyone remember the link to it? Thanks much!

Fingers

I'll give it a shot I have to take my upper intake manifold off one of these days to replace all the vacuum lines and swap injectors... at the same time, i'll just pop the TID off and make my new one.

Hmm ... perhaps the welding would go a bit better if I use thin rods?

jetfire76

how do you guys stabilize the intakes? i've seen alot of pics of TID mods and i never see any sort of brace for the AFM. they all look like they are just laying on the chassis.

I have one on ebay here: http://cgi.ebay.com/ebaymotors/ws/eB...tem=2420442955

mine just lays on the chasis, but you could make a brace. i'm gonna make a cold air box eventually, so i didn't bother.

Pick a handy bolt somewhere on the chassis and make a bracket from a length of flat bar to go between that bolt and one of the bolts on the AFM.

The problem with that is that the weight of the AFM combined with the constant rocking of the engine can cause the whole thing to wiggle off the turbo over time, causing air leaks.

Fingers

This is true. One day i forgot to bolt down my TMIC, and blew tha facking thing off the hose when accelerating rapidly

hey 2a+ron, i just bid on your tid... if you wanna end it early ill send payment out tonight and extra to get it priority shipped, i want to have it by friday for a show im going to be in

Dougster

Good pic of yours Need a t2...And yes 2a +ron, yours looks good too. I saw the place online for the 89+ up TID, any one have a good writeup for the 87-88 T2's? Thanks!

NZConvertible

They're the same.

i've never had that problem and i've had it for about 6 months now, but like i said i will be makeing a cold air box and that will be the "brace".

NZConvertible

Others have...

Fingers just get it on a mig. I bought an arc... I wish I would have spent the extra 200$ and got the mig. Arc is ******* annoying to weld with, the gas makes such a difference its not funny. Plus mig beads look nicer.

2a+RoN

you just gotta have skills with the arc...

hey amused, check PM's!
