Drag and Drive Baja

[Schweg]

Clone- thanks man, I plan on running some auto tune time and trying to get this thing up to snuff. I’ll scale it down I was looking at it last night and kind of amazed at how high it goes

Mario- thanks, I did not add a 10k resister. I’ll have to scrounge one up at work. Sync loss was a thought.

Thanks for the inputs!

Update:

Mileage: 3 ish

So got a 10k resistor for the VR sensor.
Played with the fuel map as suggested by clone. Fired it up to get a little mileage on it and try and auto tune.

Pulled away from my house running at around 2k rpm. Annoyed but hoping it would drop some once the engine is warm and wue finished.

Leaving the neighborhood and pulling onto a a 45/55mph road I give it the business.

Pulls pretty good then boom sync loss again,

Pull into the next neighborhood up and try to look at the idle. * noticed mistake one * in my rush to get this thing together and test run it I only had one bolt on the throttle body flange. So that explains where my gigantic vacuum leak is. Pushing on it alone sealed it better and the idle dropped down pretty quick.

Here comes issue two. I’m pulling onto the 45/55 mph road accelerate to about 25/30 falls on its face, feels like sync loss.....

Then I remember that I put about 3/4 of a gallon of gas in this thing.

Throw on the hazards did I mention it’s dusk.

Start pushing / riding the nerf bars.

Long story short I had about 1/2 mile of terror bob sledding the Baja home then a 1/4 to the drive way.

I’m stoked and mad at my self got more hardware on the flange. Tightened the gap on the VR sensor and added some fuel. Gonna give it a run tomorrow to work.

Anyone notice there tune change after adding a muffler?

Happy Fathers Day.

Sounds like a nice work-out!

Update:

Mileage 70.

Setup,

1600 do. Unknown condition assuming all things stock.

External waste gate. ( checked ok) don’t hear any change in exhaust noise like it’s venting.

BOV is an amazon special. Haven’t tested it other then it looks closed.

Header is a 1.5” low bugget Manx style


So I have an issue and I need some help. Engine runs good. Just swapped my turbo to an WH1C Holset. With an exhaust cane blocked it’s a .73 AR turbo.

My problem is I have not seen good boost at all or minimal psi.

I have tried two different turbos.

Any thoughts or advice greatly appreciated. Still loving this thing being fuel injected. Would love to see some boost.

That is a massive turbo! My stock 1600 would barely spool a T3 with 42/48 AR.

I know it’s large, problem I have is I ran a way smaller .50 at that still was having issues.

Maybe I’ll just for a different one and sell the two I have.

[buguy]

Man I put this one on from a WRX and it is tiny! Works awesome though. Clone has one too. Maybe give one a try? I see them all the time for sale cheap. TD04-13t

[Schweg]

Got a line on two TD04-9b’s. Price seems ok. Still researching And looking, though any insight is appreciated as I seem to be overzealous with turbo selection.

I think those are too small. They are from a twin turbo set up. You would be in boost all the time I'm afraid. But if you wanted instant spool and aren't planning to boost a whole lot it may be worth a shot. I personally wouldn't though.

[Schweg]

Well that ruins my plans. Maybe I’m back to the drawing board.

They are a twin set up, off a 3.0L all the things I’m finding say that the only difference in a 13t and 9b is turbine and a slight higher A/R on the 13.

Waiting sucks. But it’s a runner just with a real complicated exhaust.

Maybe try an eBay Chinese copy of the 13t if there isn't anything local?

[Clonebug]

I have the -9B on my shelf. It's kind of small but if you want instaboost and can deal with the limited hp it will support it should work.
Here is a comparison pic of the TD04-9B and TD04L-13T side by side.



Specs for the TD04-9B are a flow of 250-275 cfm. On a 1600 that equals between 185-200 crank hp.
To compare, the TD04l-13T I run supports 394 cfm. which equals about 270 crank hp.

I would say try it if the turbo is cheap enough. I paid about 25 bucks for the TD04-9B.
It will be instaboost and great around town but if you are cruising the freeway and have to climb any 6% grades you will be in boost and could possibly get high intake temps which can cause a little detonation.
It will probably go to positive intake pressure if your cruise speed is over 60 mph too.

The Holset H1C is a pretty big turbo and will probably not spool at anything under 4000-5000 rpm. If you had a high revving engine with some decent heads and a big cam you might be able to utilize that turbo. I have a HY35 waiting for a project upgrade if I ever am looking for a challenge.
Since I'm heading to California with the buggy in 9 days that is on hold until next winter.

Thanks for the information clone.

I’m going to hang on to the wh1c. I want to do a compound turbo setup some day. That was why I bought it to begin with. I don’t highway at all currently. The guy looking to sell wants $100 for two 9bs which seems high. Maybe I’ll offer less. I’m torn as well cause all my flanges are not a td04 or Mitsubishi. They are all t3 so that’s another cost.

On the plus side I’m still impressed with what just an injected 1600 can do.

[Clonebug]

You will probably have to make your own flanges. I never looked for them but they might be available. I plan on making my own if I ever use it for a compound setup.
I also have an IHI RBH5 turbo that I ran for a few years. That is probably what I would use for the compound turbo. It would boost 13 lbs by about 3000-3300 rpm.
I am making more power than that turbo can support but it did well while I was learning.

[Schweg]

Yeah...

Building flanges is not one of my favorite things. But I have access to some awesome equipment right now so if I’m going to do it now is better then later.

I shot the guy with the 9b turbos a message on price. No response yet. Part of me wants one to learn on that smaller quick boosting turbo. My current injectors are gonna run out at 120-140hp anyway. So looking for 300hp is a dream years down the road and after more upgrades. I also think the 9b in a compound setup might be an awesome way to spool the Holset.
