T-bolt clamps info please...

Not sure about the Greddy piping, but stock requires nine 2 1/2'' and one 3 1/4". The Napa part numbers are 7051532 and 7051534. Try www.napaonline.com.

Thanks, this is a good starting point.

I'm pretty sure the Greddy FMIC piping is going to be very different and probably larger than the stock setup. Anyone?

That helps, but I still don't know the size of all the connections. Like is the IC in the same size as the Intake? Someone out there has got to know exactly what sizes I need and how many of each.

You need 9 of the 2.44 min clamps and 1 of the 3.25 min clamps. I can't remember the NAPA #s but you will be able to look at NAPA's catalog while you are there and it will tell you the available clamps with a column calling out the min sizes. The 1 clamp goes on the throttle body, the other 9 on the hose connections all the way from the turbo outlet, through the IC, across the bottom of the car and back up toward the throttle body.

Sorry to bring this back up but these sizes are NOT correct. It seems as though there is a substantial size change as the I/C pipe enters the FMIC. The inlet on that is smaller on the left side and substantially larger on the actual FMIC. That coupling from Greddy is also a step-up coupling to fit the size change. Now I haven't bought these bolt clamps yet but I'm about to order them.

Does anyone with 100% accuracy what the sizes are from the Turbo, through the Greddy 3-row FMIC piping, into the TB?

Dude, whip out a fuckin tape measure, go over each pipe and connector hose, write down your measurements, then post here.

If it was not clear, the clamp sizes and quantities are exactly what is needed for the stock IC and tubing, nothing else. I know they work because I have replaced every clamp for the stock setup. Sorry I did not make that clear.

Nah it wasn't clear, but when I went to eyeball it just before buying the clamps, it became very obvious.

So that being said, I'll ask one more time if anyone knows the correct sizes for a single turbo with the Greddy 3-row FMIC.

I can't speak about the Greddy piping/single sizes, but I can say that the 2 NAPA stores in my area did not know anything about T-bolt clamps. I found that the best place to go was a large HD truck parts store, they had all the sizes and the cost was 1/2 what Turbonetics (or the local speed store) charges - about $2.00-$2.50/clamp. Also, you should be aware that the clamps have a fairly wide diameter range so you can sometimes get away with the next size smaller, which is better if they fit IMO as you don't wind up with a long exposed bolt sticking out after they are tightened.

I have 3-row for stock twins. I assume that all piping for the singe is the same other than the stock twins "Y" outlet, which is smaller than the rest of the piping and comes with a reducer in the Greddy kit.

That said, it takes 9 of P/N: 705-1534, you might need an 10th one for the single turbo outlet if it is the same diameter as the throttle body.

You could also measure the circumference of the silicone connectors. divide by Pi (3.14xxx), and go to www.napaonline.com and search the 705-153X series of heavy duty clamps.

This can NOT be right. There is no way the same size T-bolt clamp can fit on the outlet of the pipe on the left side (turbo side) of the FMIC that fits on the inlet FMIC side. There is an adapter coupler there from Greddy that allows you to visually see the difference. The piping before the FMIC is smaller than that on the right side going into the TB. They have to be different sizes. I'm guessing everything after touching the FMIC and after is 3.00", but before that I can't tell.

Also, I do not understand how your formula works to find the right clamp size minus the connector.

That formula is to find the circumfrence of a circle I believe. Measure across, do the math. You might also use a cloth tape measure and simply wrap it around the object to get the correct diameter.

MY FMIC has the same size inlet/outlet on both ends of the IC. The coupling (reducer)you are talking about is for the STOCK twins piping, which is smaller than the piping for the single on the input side of the intercooler. The LARGE (800mm) end of the reducer goes on the IC inlet, the small end of the reducer connects to the piping that goes to the outlet of the stock twins. The outlet side pipe is, as far as I can tell, identical for both the single and twins.

If you don't understand that you can use a tape measure to get the circumference of the silicone connectors and divide this number by Pi to arrive at the diameter then I can't help you. If you figure only the size of the pipe you may end up with too small a t-bolt to fit over the pipe + silicone connector.

bump... I am about to order t-bolt clamps to replace my 3-row setup. I am not anywhere near the car right now so I can't measure. I was wondering if people could post exactly the clamp sizes I would need for a greddy 3-row used with a single turbo setup and stock throttle body..

Thanks
Mike

I found the best fit was to take the coupler ID and match it to the clamp. I bought mine from www.partssystem.com. 2-3 bucks a pop and quick shipment.

Frakin NAPA in town had no fu**in clue what t-bolt clamps were. Everywhere else they wer like $10 a pop.

guys CHILL.........
napa calls them their premium clamps.....then, in their book it mentions T-bolt clamps......if you ask for T-bolt clamps they get dumb real fast.

Ask for premium clamps....you'll get your T-bolts......
