I've been experiencing some boost creep the last 2 weeks, and it looks like the Deltagate was seizing. A failed repair attempt led to no wastegate saturday morning, with a track day on Monday!

Thank god SoloRacer had a Tial 40mm handy. After a few hours of emergency calls to welders, the unit's installed. There's no muffler on the wastegate exhaust port right now, but it's the best that can be done on a Saturday. It's quite loud when the wastegate opens up! After 20 mins of tuning, the Tial holds boost much more stable than the Deltagate.

Here are the pics of the wastegate installed. Again, thanks SoloRacer, you're a life saver!

 

Good Choice! Clean Install. I like the braided vacuum line. <img src="graemlins/bigok.gif" border="0" alt="[thumbsup]" />

 

Very tidy!

 

Rage: No problem...except that it isn't a 46mm wastegate. It's a 40mm Tial wastegate. I was going to use it on my RX7. At one time I had a 46mm and a 40mm wastegate with plans of putting the 46mm on my RX7 and the 40mm on my 951. With the big turbo on my RX7 I was thinking I would need the extra large gate. But when I found out that the 46mm wastegate had one flange that bolted straight up on the 951 I decided to use it there instead - I had to cut only 1 flange instead of two (I have my wastegate plumbed back into my downpipe). Max - the guy with the big turbo black RX7 you met at the Beyond.ca meet - is using the 40mm wastegate on his car and has no boost creep problems.

Thanks buddy! Stop by the beyond.ca track day on Monday, I'll pay you for the wastegate there. Edited my profile with the proper wastegate size .

So far so good, AVC-R is dialed in nicely now, holds 1.10 kg/cm2 perfectly in every gear. Gotta dump in some 103 octane on monday and run 20psi at the track.

The deltagate didn't have any creep problems until the last 2 weeks. The wastegate lasted 2 years before dying. Very happy with the Tial.

 

Rage,


That appears to me to be a 40mm unit.You said 46mm in your post. Just thought you might want to know.Here is a pic of the 46mm wastegate.

 

What do you get for that kit with 1 bar spring, Tim?

Yep. Corrected my sig and post. Thanks for the heads up!

On what side is the Tial 46mm wastegate bolt-on?
Is it the side from the crossover pipe?

I was thinking of getting a 40mm tial because it's a bit cheaper and is plenty for my power goals.(325rwhp)

 

Edman951: Yes I believe it's the crossover pipe part that the 46mm wastegate is a direct bolt on. It's the part that goes back into the cat bypass that needs to have the flange cut off. There is also a large bracket/hanger that gets cut off in the process. Tim's picture shows the pipe that I speak of - with the Tial flange already welded onto it. The flanges on the 40mm gate are smaller and would have required me to cut and weld both the crossover pipe and the pipe that goes back into the cat bypass.

 

Special tool,

The 46mm kit is $675 with everything you see there.The guy that does our website made a mistake on the pricing.

 

can I see pics of the 46 mm plumbed into the DP?

 

Little OT for the thread, but what kind of clutch issues have you had with your upgrades Rage? How much did the stock clutch hold before it gave out? Thanks in advance!

 

Luke,


Here you go.
