Hi people

I need to weld my wastegate on a standard rb20 manifold i know it can be welded on the top but i really need it welded on the bottom. Now my car's pretty bare no air con no nothing so it shoud fit if i run i 2" pipe down and then mount the wastegate. The question i want to know is how much will it cost to weld that up to the standard manifold and what is the downside of doing this. and no i'm not going to buy a manifold with a gate on it cause i've been through 3 of them already i just want to use the standard one.

Cheers

anthony

might be a bit difficult to weld into the standard cast manifold.

dunno, probably can be done with alot of the heat concentrated into the manifold. maybe you could find someone who has done/will do it.

however, the way i've seen it done is to buy/make a piece that goes between the manifold "outlet" flange and the turbine housing "inlet" flange. this piece is essentially a box with flanges to suit the manifold and turbo then have a pipe coming of it (downwards if you want) with a flange to suit the external gate.

I have to ask, why have you been through 3 of them?

There is absolutely no reason you should have unless you cut a corner and purchased a cheap sh|t one and didnt re-enforce it correctly

All of them were reinforced and i had flex pipe installed on the exahst but they still cracked and they were fairly cheap though

    • HKS trigger kit should be very easy to integrate with a Link. It's a 36-2 crank trigger. Hard part is finding the motivation to take off the timing belt and everything on the front of the engine to install it. You also need to cut out a hole in the oil pump housing so the sensor can read the trigger wheel. Changing out the cam sensor for a 24 tooth setup is probably good enough but as others have mentioned depending on what underlying assumptions are changed it becomes more of a problem. Reading the crank state off of the cam is an abstraction that works in the general case, but if you have an edge case it makes less and less sense. There is a GTX2860 gen 2 that can take a compact 5 bolt housing so it's direct bolt on but I'm not 100% sure of what's involved. Peak compressor efficiency drops off a bit on these turbos vs -5s, 77% vs 73% but you get way, way wider region of operation. The -5s have a really strange surge line in their compressor map that is all over the place. If you think the hot side on the -5s aren't open enough you can try the Tomei T550B turbos which a local tuner seems to be happy with:
