Turbo hotside

[warrencross]

Hi could some one tell me what difference it makes with the turbo hotside has mine has the 2 washers for the waste gate but some people have been on about a singke washer. My washers are rattleing is ut ok to weld these and also I have no elbow my exhaust bolts straight to the hotside 5 bolts

Bigger the hotside the more exhaust flow.
Single puck is bigger and has less items to fail. Twin puck obviously has 2 items which could fail.
You need either one one as that is what controls your boost.
Your actuator opens these to allow the exhaust gases to bypass the turbo. If you weld them closed your turbo will have unlimited boost.
Your elbow is required because it allows both exits of the hotside to flow into 1 exhaust. It also houses your O2 sensor...

Sorry I mean weld the washers so they dont rattle not weld the washers./ flap closed

You can try. But don't forget it's under immense pressure and heat...

I think you'll find most people call these "single flap" and "twin flap".

Twins had a problem with warp and let air leak past on the higher powered version so Mitsu change to single and most ar after a sinigle flap 10.8t like those on the 8mr.

I wouldn't weld the washers as the flaps have room to move and fit into the hole as they wear and if you weld in a position that isn't air tight you'll be knackered.

Why weld? Is it making a noise?

Yh its making a noice and not sealing properly ive dropped it at an engineering place they gonna sort it for me hopefully

Sounds like ususual warp issue I'm afraid. 2 bits of good news are;
- you can swap over the hot sides really easily so just need get hold of a 10.5t single flap.
- I have a low mileage Evo 7 FQ300 9.8t tein flap complete turbo on the shelf if you get stuck.
