Jenga's Project Yaris

[MHR1294]

Even at 170hp I bet that thing goes like a rocket, they don't weigh anything!

Less joins the better! My friend spent a whole day tightening up clamps on his evo...

That's a good service from Haltech, did they tell you what caused your first one to die though? Wish I could afford to get a Haltech - the usual I'm spending all my money on importing a car instead.

It's good that you're doing it over a long period of time, like you said, sorting all the minor issues out. there's nothing worse than modifying a car and then having it go bang.

you still around and working on this jenga?

[Jenga]

Yep, still around. The only changes since the last post are that the boost was wound up to 24psi, I installed a new set of injectors (850cc Siemens) so I have the option of going to E85 and it has a new set of RE003's. Traction is an issue, haha.

It's all just worked and continued to work, quite amazing for a project car. I want to have it retuned to run E85, but I haven't gotten around to it yet.

[MHR1294]

You know, there's jokes about Marty and Moog building a Yaris and they say they will do it.

100% you should duel them with this!

I tried getting RE003 here in the UK but they're so soft they're banned for road use, so I have RE030 instead

[Marty]

This is excellent!

[Jenga]

Since upping the boost, I've had a few issues with popping hoses... It would happen about once a week. Yes, I know that pipe isn't rolled, so it's a miracle it's even held at 24psi.



I've been meaning to tidy up the intake piping for some extra stock looking-ness, so I spent a few hours and installed some new piping.





Looking good

[MHR1294]

Brilliant,

So the intercooler there, is that running it's own coolant circuit I assume? I guess that's fixed now that you've managed to up the boost?

I was excited when I saw this https://youtu.be/GViEvMdAQCo?t=190

14.22 at 102mph! that's epic man.

Was that your fastest time and whats your power figure looking like now?

[Jenga]

Nah, that was actually my slowest time. My best time was 13.7s, really happy with that.

The final power figure is 200hp - the tuner just couldn't push anything more out of the turbo. I'll admit I was dissapointed with that number, until I drove it. The good part is that the redline was raised from 6200rpm to 7500rpm, so that helps a lot.

To go any further will require a new turbo, and to be honest, I'm happy with its current configuration. It's been super reliable, good to drive to and from work and is generally enjoyable to drive. For the most part, it's achieved what I set out to build.

[MHR1294]

That's fast man! Hahaha, so unsuspecting too.

Sounds like you've got a good strong 200hp though, not a peak over 100rpm like some people quote.
All about that area under the curve

To go any further will require a new turbo, and to be honest, I'm happy with its current configuration.

If you do reach that level, as much as it's played out, the good old TD04-13T from a subaru WRX is a nice upgrade.

That's what you're running right now.
Compressor: 40mm - 51mm
Turbine: 38.9mm - 47mm
304CFM max, and a .63AR

It would be a decent jump in top end without sacrificing much of the noticable bottom end, IMO.

Or a TF035, with a Hybrid TD04 front side, if you wanted more, without almost any lag.

It'd just be nice for your engine if you could get that boost level to more like 18PSI or so, flowing the same.
Poor little guy's screaming it's head off making that much back pressure on turbo side.
