Hey Guys,

I have an older Tial wastegate and I am trying to find the gasget that goes between it and the manifold. Now I have been told it should have a raised beveled edge on it to help seal it but have been unable to find one can anyone help??? A workshop has been looking but so far have been unsuccesful at locating one and can only offer purchasing a new one.

As the wastegate works fine and I really don't want to have to buy a new wastegate if I don't have to.

Cheers

Mushroom

were you after that metal ring that goes into the end of wastegate or and actual gasket? if its the gasket im thinking of you can buy them from autobarn. turbosmart make 38mm sized ones, not sure bout other sizes tho.

well it bolts on to the manifold which is flat and has 4 bolt holes, so I am thinking there is suppose to be a gasget that stis between them and has a raised beveled edge to help seal it . I will take some photos later this week to expalin more if it helps

does the wastegate have the seat area machined out ???

as you can see the samll ring that inserts into the flange area between the gate and the manifold .. is this the bit you are missing?

try to speak with tial USA and see if can get that part seperate from them. as that ring seals the valve to the sides so it doesnt leak

yeah, no chance of goo working there

either have a replacement machined up on a lathe

OR

buy a new one from tial USA - or try Slide as he got my tial from japan and might be able to get the individual part

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out

      I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.

      I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
