Turbo BS Thread

Why did you make the v-band flange flat?

 

Alright guys, I'm looking at alternatives to the haltech. A few guys I race with have these on their turbo miatas. Anybody seen/heard anything about these?

Just curious, has anyone ever done a setup where Maf was pre turbo for the 2nd gens?

 

Looks like another speeduino based device, this one is made by people just up the street from my house and is also speeduino based.

There was one like 10 years ago, there was a thread about it in the performance section somewhere... It was an x runner if that helps in your quest lol... Title may be something like "low end torque mod" or something seems like

 

Thanks for the lead!

 

this. i converted my cx manifolds to male/female style vbands. much better

CX used flat flanges on everything and i figured a flat flange would mate up better to the turbo down pipe since it's flat. I was just going to use the female side but thought if they machined the male end flat it would give it a bigger surface area for the seal

 

Same shit is same, both styles leak anyway..

 

I understand M/F is a superior flange but I'm not a welder and don't really want to cut all the fittings of and redo them.

 

I found a shop who will Cerakote the manifolds, will take them in tomorrow for all the details but I'm glad to have found a local shop.
Now I just need to pick a color

 

You should test fit everything first.

 

Male/female seals better. All flanges leak if they are warped. The techniques prevent that.

Agreed^^^ Definitely test fit first.

 

Noted I'll do more of this tomorrow and over the weekend

 

It's go time!

 

Woot!

 

how is it, things warped at all?

 

It all felt good to me.

The flat Vband flanges can be a pain to keep squared I see how the M/F flanges would come in handy.

The oil drain being at the 6 o'clock position Will be a tight squeeze

it might be better fitted on the other side of the T4 flange at say the 5 o'clock position.


I'd like to order two high quality 2.75" Vband clamps for the crossover pipe. For now I just have better nuts on the clamps that came with the CX kit.

Turns out the 3" male flange I had converted into a flat flange isn't a good fit. the outer diameter of the flange was greater than that of the turbo's flange so I'll take the Evil Energy one I have on hand (that matches the diameter of the turbo flange correctly) to the machine shop to have it de flange gendered.

The father and son that own the machine shop both drive Tacomas so that's a bonus.
