Well I ripped out the HKS EVC because I will set the boost with the wastegate spring, I don't need adjustable boost, I don't have any self control in the heat of battle. I will probably put it up for sale, anyone interested let me know what it's worth to you. So I pulled the intake pipe for the moment and just slapped a super power flow right on the turbo. I will not do that in the final version, I will box the area behind the headlight and insulate all piping. The compressor is hot enough to sizzle water after a few runs. I will be using one of my MBCs to turn the boost up to the max I can run on the final combo and then get the appropriate gate spring to get that boost level without a boost controller. To reduce spikes I made the hose run as short as possible but it still pops up 0.1 higher than intended and drops down to the set boost. So the T04 on a stock CA18DET responds instantly, I would reccomend an A/R .63 turbine housing for anyone buying an E new, the .40 is what the kit turbo was so that's what I am using but IMO it comes on boost too snappy. I was screwing around yesterday in front of my friend's shop. I revved it up to about 4500, dumped the clutch an the car shot off the squat and the tires went up in a cloud of smoke. When I got off it there were some thick snaking black lines 30 feet or so behind me. Don't fear the big trims, they will spin, I have stock cams! So I slowly start turning up the boost finally getting it up a bit from 0.4 to 0.5, spiking to 0.6 when the turbo first spools up. I do a couple of 2nd gear slow climbs watching my A/F and listening for detonation. It's really hot here, think Texas gulf coast so I could still start popping even at a nice mixture with the intake temps. So I start seeing it lean out, give the GCC a click up on the two higher RPM bands to throw some more fuel at it. With the light air today I suspect on a cool night I will need to add a little more. I think I have it about as high as I dare until I get some subs loaded in and a colder set of plugs so I call it a day. I am heading back to the house and decide to drop it on a roll and see how it pulls. It takes off nice then I feel "something" happen. You know when there is no noise, no shake, no twitch of a gauge but you just know something happened, like some jedi ****? Well I got that feeling and immediately got off it and pulled over. I popped the hood and start looking for a blown hose or something loose. I notice the idle is high and then it starts hunting, I look at the idle control solenoid, here is what I see. I damned-near snapped the plug off! The motor must be rolling pretty strong when the boost hits and it smacked the hood. I should be pissed but I just laughed. I enjoy a WTF? thing like that; I always seem to break strange items. Better than something important! I also had to pull the stut bar I had been using because the turbo is in the way. I laid hands on a Cusco which is the only one I have seen that will sit back out of the way like this. I sandblasted off the old paint and reshot it in red. I could definitely feel the difference when I yanked the strut bar and really wanted to get a replacement. UpGarage and $40 later it's back to being stiff.Now when I was screwing around under the hood I notice that one of the big bolts that secure the turbo to the manifold is ****ing gone! Huh?! One other needed to be retightened too. I need to figure out a way to lock these bolts in place, this is stupid. Maybe drill across the heads and safety wire them.

Hey you need to come to Germany and hook my ride up. Mine needs a little more you know.

I am putting something together here soon but it is probably going to go into an old school opel. I will need your expertise on soem things but hopefully in about a week it will be together.

At least you didn't break anything important. Do you perhaps need new motor mounts, or stronger ones?

As for the safety wire thing on the bolt heads I say go for it. That's how us OG ballers in the USMC Airwing do things.... If it's good enough for 7 million dollar FA-18 engines it should work on the ol trusty CA.

I hope you guys are less ghetto than us MT bubbas, we did some crazy **** to keep them trucks running. That serves me well still as I keep buckets going faster than people expect.

Nah I think the Opel GT's are ugly. They look like little retarded corvettes.

I was thinking more along the lines of a Late 60's Rekord or Commodore. Whenever this damn garage gets built then I will start really looking for one. We will see.

Just make sure you have room for my wife I guess she can hold onto the roll cage

I had two GTs and three Mantas in high school. The GT looks like vette because prominent GM guys designed it.http://www.opelclub.com/html/opel_gt___faqs.htmlNot sure how you couldn't love such a sexy machine. I would seel my Skyline in a heartbeat to get another GT. I love them except for the transverse leaf spring front suspension. Barring that a Manta or a Kadett would be a lightweight car to drop it in. What's the scoop on the Calibra?http://jp.youtube.com/watch?v=vm4A8G4hDXMI see some are 4wd and I like the look. They sell them here and I have raced one in the T, I walked him like a dog but his was bone stock whereas I had a few goodies, it wasn't slow just not faster than me.

How is the life out of your wideband? I notice its in the stock(ish) spot, and I was a little worried about the high egt's there cutting the life of the sensor really short.

if you want to sell me that evc for next to nothing feel free to email me. actually, i freaking get paid friday! totally email me. also, if you need that thing you broke you can have mine. its in the trash but i can fish it out if you want it.

Not a big fan of the Mantas but I had a Kadett-C but it had a 1.2 in it and about 55 hp. The front end wouldn't have been able to handle the weight of the CA. A 1.6 front end could have handled it but they aren't so easy to find because they are swapping 2.4 and 3.0 in those things.

The Opel GTs if done up tastefully dont' look so bad. It is just over here some are still infatuated with that stupid wide body crap or heep loads of body kit and maybe that is where I got that distaste for them. I have seen some nice ones though. I guess the CA would be a good donor for one of those. I will have to keep an eye out but I like the look of some of the other opels here. They seem to be smaller versions of the big v8 muscle cars.

I will get you a opel gt and you give me your Skyline

wow. The drive to work was fun. On a turbo this size a little bit more goes a long way. At 0.5-ish it feels like the S14 turbo at 0.9. The response is amazing, the needle on the boost gauge twiches up at the slightest hint of more pedal. Man I can't wait to get those subs in and start creeping up the boost some more!

seems fine. I have had it less than a month though. I keep reading these sensors die quick so when I am satisfied the fuel is good I intend to take it out. If you look at the factory O2 sensor it is in that location too and lasts for years.

TMS when you say boost comes on too snappy, how snappy are we talking? Where does it start and when does it hit full boost? How is it off boost, I know its a 1.8?My ka-t is shot and I'm about to be in the market for another engine.

It drives like stock off boost and full boost is in by 4000. I can smoke the tires at will coming off a stoplight.

My t3/t4 made my mom scream and me when she rode with me for her birthday for the first and last time (I showed her what the "whoosh" noise was when she asked). If I was to run your setup, she just may cry.
