V2.0 993 turbo Y for 930's new design

[mb911]

I decided to revise this design for the 993 heat exchangers. this is 100%volute and is about as good as it gets without center mounting the turbo. I have the ID and OD polished right now so I will have better pictures next week. this is not going to replace my first version but is an option for some. what do you think?


and this is a picture of the first(v1) more stock application

So will this put the turbo in the stock location on the 930?

FWIW, I like this version better!

yes that has been my limiting factor every time.

JCC I time studied this one from start to finish I had a HUGE amount of time in it bascially doubleing the cost to produce so you kind of get what you pay for

And now the most important question.... would I be able to keep my Monty on there?

Not sure It does work with rarly's muffler. I will be fitting up this week though and can verify

twin 38mm v band tials

What is the benefit of the new design?

Which gaskets are used at the exit of the HEs 928 111 127 02 or 930 111 192 06?

I have a gross of the gaskets so don't worry. as to the design it is just a bit better wastegate circuit but a huge cool factor

I can picture a zork pipe with two wastegate pipes on both sides!

I am going to make 1 Wg dump into the back of the center dump tail pipe and the other wastegate will flare to 3" so it match's and the from the rear of the car it will look like a GT3

That should be an interesting look.. So one Turbo w/ 2 Waste gates?

yup its a volute system (twin scroll setup) though the turbo is not

Give yourself some room for thermal expansion between the watsegate bodies....they look awful close together. The flow path to each wastegate is much better than previous design where you reverse direction on one of them.
Damn you do great work man! I regret buying my GSF headers 2 years ago.

Will you do a trade in policy, ha,ha?

good point though the engine grows apart not closer together.. Maybe a partial trade in.

The engine grows further apart agreed, but the pipes grow linearly.....and they will grow towards each other the way they are laid out here...overall you may squeak by ok but to be safe give yourself some room in the beginning.
How much credit for a 2 year old GSF header system with heat?
