Defined Autoworks Engine in my GTUs
 

The guys at Defined Autoworks built this. I haven't driven it yet but I will soon.They also built the exhaust back to the catback.

Should put links for large pictures, unless its my computer. Looks awesome from the little I can see, though. Any power estimates? That header looks great.

That header looks like it will heat up your engine bay a lot. 180 degree u-bends that close to the engine will get really hot. Get some good heat shields.

Heat shield is being made if not already. It is suppose to be around 230-240hp. Need to break in first. Not sure how to make the pics bigger. I'll take some when I get it back.

very interested in getting a closer look at this thing.

Don't be surprised if they glow. :)

I guess that explains why they did what they did to the headers...

What is the porting?

streetport, haltech, and a lighter flywheel
here are earlier pics Logan took

Saw your car when I was out there, looks great :) I swear Ive been searching for a clean GTUs for years. Ive owned 3, but everytime I jump on one it ends up being a POS.

Built with RX-8 rotors?

Thanks Rx, The car is a little rough for the low mileage but I will clean it up. I haven't driven the car at all. Logan says it rides nicely so I am excited to get it this week. I plan on cleaning up the interior and body so that it matches the new performance.
I have to say, I have been really impressed with Defined Autoworks. Logan is a good person and is very talented and specific. He has a lot of pride in his work.

I'll get some bigger pics now that I have the car. Until then Ray, I will say it is sweet.

getting it tuned soon

Wow

finally ... :)

haha Yea I know. I kinda went crazy with this car in a short amount of time. So far I fixed the antenna, new ftp lenses, Replaced the triangles, Got new custom floor mats, got 8 dings removed, installed a turbo front spoiler, a coolant panel, rubbed the paint a lot, cleaned the interior a lot and installed a Nakamichi HU with JL XD amp and C5 speakers.
I think the original brake pads are still on the car. That's next.
Oh and I'm picking up the driver seat tomorrow with a correct cloth seat cover on the top half. The po was 80 something and rubbed the cloth off the bolster.
I'm obsessed. I'm hoping to get it dyno tune next week now that I have the engine broken in.

So Logan has two GTUss at his shop. Mine finally made it there about three weeks ago. Now it's time for Logan's magic!!

Good luck with your baby...

Would love to see some galleries of the car.

Are you going to do a vented hood ram air, or cold air intake or anything? Some of those vented hoods are primo

I'll be very surprised if it hits 230hp. Also you should consider wrapping those headers it's gonna get hotter then hell in there!..lol

if anything i'd ceramic coat the headers - but that heat shield you've got in there is beefy! I like it!

Ultimate would be to do both - ceramic coat header and have the heat shield. Shit ceramic coat that too!

Thought about it but I like the stock hood. would like the cool air though

You might use some of that gold heat reflector tape the evo guys are so fond of:

Gold is often referred to as the best heat reflector. I'm not sure how expensive it is though.

I may have Calico coatings do the coolblack coating. I had a downpipe done and was amazed.

Nice where are they out of? Performance Coatings in Auburn WA do ceramic coating on headers for ~$70 to ~$100

I had them do my intake mani after I saw the ceramachrome they did on my buddy's header. Top quality work.

Why would it be surprising to hit 230rwhp? You do realize this is the same engine that already made 230rwhp 5 years ago in my 1st gen right?

I wouldn't know I don't keep tabs on peeps!...

They are in Denver North Carolina. They do work for NASCAR and were really cheap surprisingly, but that was in 2006. Did my fd downpipe for $60 $20 for shipping. I would have to say it would be more now.

You can put your hand on the pipe after engine is warmed up. I didn't think that was possible but...

Engine bay looks legit, I like how much room there is in there :nod:

What do you think it will get?

Uh...what?:scratch:

Now all I need is to make the paint shine like your fd.

so whats the price for one of these buggers?

Uh mmmm probably 229hp!!!...

Confused there old fella?...lol

It made 227hp, not bad with power steering, a/c, and a restrictive RB catback and the stock fan. Just an electric fan would have allowed 230hp+. Logan has proved that.

Logan wanted to do the full exhaust but being an old guy, I like a more quiet exhaust note so I can listen to my classic rock cds while I drive around my old Rx-7. lol

Dyno Jet?

I assume it was a Dynopack which I believe is what Logan has used in the past. I will get the paperwork soon. It was tuned this past Monday.

That is awesome!

I'm sure everybody including myself would love more photos of the header! Or the whole exhaust system. Any idea on the primary length before the collector?

Logan got rid of the Dynopack, did he not give you the dyno printout?

Cool!...

I haven't picked the car up yet.

He made it a little shorter than he wanted, why he didn't say but it is fine. I wasn't out to set a record. I just knew he does great work and wanted something different. Probably 100hp or so more than stock. I probably killed some hp wanting the racing beat presilencer and catback. But I wanted it somewhat quiet so it's the price you pay.

Actually the hp is pretty impressive considering how quiet it is.

Found out it was a Dynopack

We are definitely happy to make 227 with such a quiet exhaust. The header was built using my formulas, but the racing beat exhaust threw it off some. Now that it had been to the dyno, I think adding 2 inches will add possibly 10 hp. We were running break in plugs too, which new ones add 2 hp or so. I think the car has 235-238 in it. Rick is a great customer, very easy to work with. I won't be disclosing the length, but pics of the whole system are on our Facebook page

^Thanks Logan! I took a peak at the photos on your website with the longer systems and I must say they are impressive!

So was this the exact engine from the test mule, or just the same setup?

As far as I know, it was close to the same except the test engine had more of a free flowing exhaust.

Got the GTUs back yesterday. Haven't had time to really drive it. Drove it in the wet today. couldn't really do much. The engine sounds great. 226 hp Logan has the dyno info and he will post it.

There's more power there. I just like how quiet it is and how the engine sounds. It's a beautiful thing. I may have said that more than once now.

I haven't had time, but we did take some footage of the dyno runs :-) Will be downloading soon. Might be back to our shop for stage 2 also, so stay tuned.

I can't wait to see some footage! I've been wanting to hear a 13B on the defined headers, but no one seems to have any videos of it.... Quick off topic question for you Logan, are your 6-port headers made for stock ports or for more of a street/bridge port set up?
