Boost addicts 90 na, 2002 vvti engine, t04e twin scroll turbo, fully custom build
 

Hey everyone, it's been a few years since I've logged in here. I was out of the country for a bit setting up and managing a company in Kuwait called Bullet performance, all High performance exhaust systems and turbo systems. Recently I got back to south Florida, working on a few things, and getting my own high performance exhaust and turbo system company set up!

You could say I'm a master fabricator and welder, so you all will enjoy seeing me put together my car.

Heres a few pictures of some recent work of mine for those of you who like seeing high quality custom fab parts.

Ok ok enough of all of that.

So so I got my old Miata out which had (literally) shot some engine parts into i95 about a year ago. It was really dramatic and hilarious, a huge explosion of fire, Rods tumbling on the highway, just epic.

So ive got this 2002 engine, 60k on the block and a refurbished vvti head, so let's call her half new. I'm going to run her at 10psi on this lower end, but I'll throw a built block in later and turn the boost all the way up. Expecting 250whp or so at 10psi, but with a built motor I'm guessing 450whp? We'll find out.

So so the turbo manifold is the first thing I'll start making. Building her a totally equal length turbo manifold in schedule 10 stainless pipe. 1.25" to start but it will actually go up to 1.5" before merging, a true stepped runner design. Again this will be a twin scroll manifold. Now even though I don't have ac and power steering on my car currently, I want this manifold to be able to fit with both ac and power steering, as I plan on producing this manifold In production, so.. It's gunna be a tight fit! Kind of a side mount setup design.

Here's a little work I started on. Didn't like how my exhaust housing didn't have a way to center my Vband, so I lathed a little grove for the tube to center on. Also took the time to machine off the stupid lip on the Vband itself that allowed it to work for 3" or 3.5"... Let's be real 3" flows way enough.

Heres a page of some sketches I've done on the turbo manifold

Heres a box of stuff I ordered. More stuff on the way.

Stay tuned! Gunna pull the old motor tomorrow and start dropping in the new motor Saturday. Figure I'll finish her up within a week or so after that.
Side note too. I'm at a maximum $2000 into this to make her work completely. That's including the motor with its included ms1 I'm getting from my friend. This includes things like a nice new tial 44mm wastegate, all beautiful and new Mandrel bends and such. So goes to show, things aren't too expensive when you build them.

Very cool to see you come back to mt.net!
A bit of praise: Your fabrication thread inspired me to design and fabricate my own turbo setup.

ah thank you! Finally after attempting 1000 different combos I figured out my old password.

Fabrication thread?! I remember it now!! Hahaha totally forgot, I'm going to go check her out if I can figure out where it is on here.

I'd love to have a manifold fabbed

we can work out something.

you running a log mani now? Excuse my lack of desire to dig through your build to find out.

I'll shift to PM

Wow, fantastic looking fab work. Pretty stunning pieces you have. I went ahead and followed because I love seeing fab stuff on my feed.

Following this closely. Also planning a twinscroll manifold.

But with a 2002 motor (VVT) you should step up to an MS3.

thank you!


yeah man I'm a big twin scroll fan! Helps out a lot on a street car.

Yeah I mean motor is 600$ with the Ecu, package deal from a buddy.. Soooo yeah for now vvti is disconnected. I'll probably upgrade her to an ms3 when I build the motor, I want to be able to control her properly at a high power level. This first run is me kind of just fucking around really.

Good. Not a bad plan.

What are you doing for a wastegate solution. I've seen a couple different options.

Twins? Or some sort of divider.

yeah twin gates are pricey, I'm running a divided setup into a single 44mm tial. Plenty of wastegate really. She'll sit right above the power steering pump, tucked between the motor and turbo.

Cool. That was my idea too. No PS/AC so I'm going to try low mount with the wastegate above the mani. Dumping down next to the downpipe.

I wanna talk twin scroll with you guys :3

Manifold is a pain in the ass to build. But you get a decent spool gain, and a small power bump. Compared to the same sized single scroll turbo.

You know. I need a twin scroll manifold built....you need an MS3x built....maybe we can work something out :)

That's possible, let's see how the numbers crunch. Pm me


Alright so I've made some moves today! Got the car over here in my shop, ready to tear out the old and destroyed 1.6 and drop in the 1.8. Should have that new motor in by tomorrow.

Some more gifts arrived today in the mail!

Again this whole turbo manifold has some key points to it that make it unique

Equal length
Twin scroll
Schedule 10
Stepped runner design
Fits with ac and power steering

Can anyone tell me if anyone else has made a manifold that fits with ac and power steering as well as being equal length, and even twin scroll? Forget about it being stepped runners, nobody has done that on a bp turbo to my knowledge.

I am loving these little transition pieces that go from 1.25 to 1.5 pipe, they are gunna flow like biggie smalls.

That's all for today. Probably Sunday I'll start on the turbo manifold mock up.

@TurboTim designed one. Don't know if it ever got made.

You guys will like this too. A picture through the hole that appeared in the oil pan.

should have read more miataturbo.net before you boosted.

why? I've built more turbo kits than I can count
