I ported my Turbo Manifold today..it is the BAE RHD Top Mount Manifold.

Sweeny was not wrong when he said alot of metal has to come out...Yikes.

Here are some pics:





That was only some of the steel that i grinded out.
Quite amazing really.
Next step is having it coated at HPC.

Looks good. What turbo you gonna have hanging off that baby ?

T3 from a SAAB 9000...well for now.

If I'm not mistaken that has a .43 a/r compressor housing and a .48 a/r turbine housing. Thats really small for any M30. I was using the same turbo on my M20 at one point and I decided it was too small because it was choking the top end(5500rpm+). So then I went up to a super 60, which has a .60 a/r compressor housing and a .63 a/r turbine housing, these are typically found on 1988 5 speed ford thunderbird turbo coupes. Big improvement, but still a little small. Now I am working on installing a holset from a dodge cummins. and this is all on a M20.
I suggest finding a much bigger turbo. I was always afraid of going too big and having too much lag, but I have learned that going too big is better than going a little small.

Yeh i know...it is going on a 2.8 though and not a 3.5.
It was just a cheap way of getting started..once everything is up and running i will Be getting something bigger....The most important part was it allowed for me to make the adapter plate to match the Mount. So now i can get it all coated and think about a newr bigger turbo later.

even though its a 2.8, that turbo is still small, my m20 is not even a 2.8, you should see some of these sweeds, they put monster turbos on the smallest engines, yet with modern technology the lag is not even an issue.

"adapter plate to match the Mount" PICS??

How hard is it to imagine a rectangle with a hole in it?

not hard at all, but what kind of adapter is it? t3 to a t4? or something else???

thats why pics would help clear that up

Well it is Wierd...basically cause i dot know what the point of the Mount on the Manifold was..cause i have not seen any Turbos with that Style mount...well not so much me but the turbo rebuilder i was talking to...prehaps Those type of Mounts never made it this far down south?

Basically had to Have the plate Machined for the t3 type Port size....but as the Holes where for a T4 Mount..really that means nothing...it is just refered to as "Large Mount".

but you can see in the Photos below.

With all due respect, I think you are wasting your time with that adapter. just slap on nice modern turbo with a t4 base.

OHHH dont show me that...Gawd...I dont know if i should Hug you or Hit you. (this would have saved me alot of time had i known such a mount excisted!)

So that Port on that first turbo in the Ebay link is the same size as the port on my Manifold?

That is wierd cause i was told by this guy that they dont Make...well not "Dont" make..but just dont excist here in Australia...he had never seen one.. (this is from a Reputable Turbo shop)

He wreckons they are either the T3 type bolt holes with the port that is on my manifold or.

THe split port type on T4 with the big bolt hole pattern...(they can be mixed...but not usully the small port with the big bolt hole pattern?) (Hope that makes sense?)

I would really ave prefered to use the turbo straight on to the Manifold instaed of an Adapter...atleast the adapter makes it a bit easy in finding a Turbo to match. maybe i should get one of the ones in those Ebay links

Thanks.

Yes, this mount does exsist. this is the same mount on the TCD manifold. the adapter you made, so many people want that for the exact opposite reason that you are using it for. because they have a manifold with a t3 flange and want to use a bigger t4 based unit. What i suggest is you search for a turbocharger off a diesel engine that is anywhere from 6.0-8.5 Liters. Usually trucks. don't be afraid if it's physical size is almost 3 times bigger than your current turbo. just get something modern. i just got a holset hx40 with a 22cm^2 turbine housing, that has a t4 base / flange. thats for my m20 engine. you can even use a HX55, on your M30, don't worry about it "only being a 2.8", I suggest you get at least a hx40, but make sure it has a bigger turbine housing with the T4 flange.

The only other thing is most of these turbos have the split entry, and your manifold is not split. Don't let that stop you from buy a turbo, you just might want to think about removing the turbine housing and smoothing out the edges so there is no turbulence and everything flows smoothly.
