Ive got a hks manifold with wastegate (not installed yet) but my 2535 uses an internal wategate. Is it possible to weld the internal wastegate and simply use the 40mm exernal wastegate?

I guess the benefits i would like to see is that the airflow from the wategate and turbo are separated although this can also be achieved by a a split dump pipe...

can anyone shed some light

Im thinking of doing the same wit hthe same turbo :(

I was going to get another dump pipe flage and weld flat flat on it. Then cut out a hole for the turbine exit (i think it's roughly 2inch) then step it out to 3inch.

you have to weld the hole where the wastegate flapper is

then make sure its smooth on the inside so it doesnt hinder flow

no you dont, just make sure it cant open, welding up the wastegate hole in the housing will just cause you dramas such as cracks, and it will take 100 hours to diegrind the weld down so it is smooth

of course you dont have to

but if you dont do it properly its just hindering flow :rolleyes:

I dont want to tack the flapper so if i sell the turbo. Instead i will make a solid rod(take off the actuator) so it is locked and wont open and if it do'es who cares as the dump pipe will be sectioned off :laugh:

      New fix for low tyre pressure from bmw

      HUMVEE are fine in big open areas, but they are problematic on the street and tight areas As for reliability, some of the  US Army guys I have chatted with have said that when they were working they were fine, but, the do spend alot of time in workshops for multiple reasons, admittedly, they did get a hard time by the boys and girls who drove them I would definitely put them in the "buyer beware" category  They do look tough as nails though

      Just don't use ChatGPT or any other artificial stupidity for the equivalent of googling. Their demonstrated inability to discriminate reality from hallucination should be enough to make them totally untrusted. LLMs don't know anything and cannot think to even the smallest extent. They are just predictors of the next word, and that should never be confused with capability.

      Another little story of weird shit happening

      By GTSBoy · Posted

      I think, given the usage model described in the OP, I'd never ever experience the wonders of the 400kW upgrade. What I really need is boost from 2000rpm and probably no more than 260-270rwkW. But I suspect that the highflow is not actually the turbo for that purpose, so I may in fact need to get a G25 or 30 or something right sized and very spooly. We shall see after it is tuned. I've had to back the boost and boost ramp off to stop the thing from pinging since the highflow went on, so I've been almost living the NA life for 9 months now! Injectors are recently in hand. AFM is in hand. Dyno is fixed. Just need to clear a queue of f**king Supras out of the way (and probably fit my new gearbox). So....some time this year? Lol.

      braided lines for the turbos

      By GTSBoy · Posted

      For what I gather is a Sunday/summer car....braided is fine. You're not going to be left without a vehicle and you have plenty of time for inspection/maintenance. Oof. I wouldn't use them that way. They can probably handle the temperature** but the internal corrugations means that their flow characteristics are a bit shit. Lots of extra friction and pressure loss. Makes them flow like the next pipe size down. ** They are stainless, and the stainless can usually be at least something like 304L, which is pretty good at higher temperatures (unlike 316L, which I would use for a wrt/corrosive environment, but not a particularly hot environment). But the welding needs to be top notch. And even then, because you usually need at least one cone-seat end on them (because you can twist the hose and do up both ends at the same time unless one of them is a union) they can be prone to coming loose with heat cycles.

      I don't have the OEM oil feed lines though and the turbo-wraparound line is torn, only has water. My plan is to get replacements for these and just connect a braided line to there. And make sure it's leak free. Hoses like these are also sometimes used to connect external wastegates, so for an EGR I think you're good using them.
