Hmmmm really? Weird. I have a 93 JDM WRX. I have no idea why my clips worked and yours didn't.

Well guys heres the bad news I was on my way to go trick or treating with the wife and kid and all of the sudden I hear a hissing and see steam. The plastic radiator tank decided to crack and and spill coolant all over the place so now the car is down till i can source a radiator. Sorry about the bad news i have to bring but it should be running soon.

I tried to send you a pm rob I was curious about the eprom products you have. I have a ej20k sti ra. all is factory even still has cat pipe on and vf24 on it, factory injectors and 6s computer. I was wondering if this might be a product for me. I like driving this car fairly regular so I'm trying to avoid the usual aftermarket route I generally go.
thanks? sorry for posting here was not really sure how to contact ya

His tunes are only for the EJ20G, although I think he was working on a 20K tune a while back, not sure what happened with that. I think your options are pretty limited unfortunately. Vipec, PowerFC and Enduring Solutions seem to be the most popular tuning platforms for the 20K.

Just want to add to the reviews, finally got my TD05 rebuilt and broken in on the 550 tune. I did a few things at the same time, so I don't know what it felt like with the stock header before.

Old setup:
1. Very leaky AP racing UEL header with a huge 2.5" up-pipe, very laggy on TD05
2. Originally Power FC tuned to 240whp at 16psi on the TD05 with 440's
3. 3" turbo back exhaust with 3" catalytic converter.
4. OEM intake, as the Apexi kept getting the MAF dirty and was prone to heat soak.
5. 02 WRX intercooler.
This setup was very laggy with the TD05 power came on around 5500 and wasn't all that impressive for the amount of lag it had.

New setup:
1. Port matched OEM header.
2. Port matched 2" uppipe with flex section to ported TD05 turbine housing.
3. Ported and polished 16g compressor housing.

So, spool with this new setup is wonderful. I start building boost at 2800 and it's at full boost at 3300 to 3400. Great down low power and just builds from 3500. At about 4500 to 5000 the power is ridiculous and pulls very hard to 7000. I'm running 15-16 psi right now to be safe and it is very fast.

Notes:
1. The compressor housing on the TD05 16g needs some porting. On mine the 90 degree elbow had huge steps and edges leading up to the inlet. Nevermind that it is very very rough. I smoothed the edges and polished this and the outlet as well. They were both very very rough. I think this made a significant difference in power.
2. I recommend port matching the TD05 turbine housing as the size is very different from the up-pipe. I think I gained a lot of spool and down low power with this along with port matching and polishing the stock header. Getting the turbine housing on and off can be a pain, b/c it is old and rusted, but it is worth it. I did this because I blew the TD05 and rebuilt it. Might as well polish the housings while you have them off.
3. Only thing I'd like now is a bigger intercooler or air to water setup for summer. Tried to fit an 08 STI intercooler in. There is no way to fit it, even pounding on the fire wall and cutting the TB. I haven't tried the 04-07 STI intercooler.

^ That's some good info. I'm trying to lower my spool time at the moment since I've been rallycrossing and autocrossing a lot. I'm still stock ECU with turbo back exhaust and a home made coffee cup mod. Haven't added the boost controller yet because the ECU pulls timing and boost every once in a while which I assume is due to knock so I'll let the computer keep my engine healthy by doing what it wants under those conditions. I've heard just installing the boost controller and not using the factory one will lower my spool time by about 500 rpm. I'm seeing full boost just over 4000 rpm.

I'm saving up for a rob tune and collecting the rest of the parts (injectors, and going to make a custom intake box with larger filter) but until then I have to rely on the stock ecu programed for 98ron fuel. I have 93 octane here in florida which is just under the 98ron (about 94 octane) which does fine for daily driving but when I'm competing and running it hard is when I run into trouble. Lately I have been mixing in some 110 octane to bring up the total octane above the 94 that the ecu wants and have had great results. Computer doesn't pull timing or drop boost and the car feels like a rocket ship even after repeated laps. This will have to due until I can get the rob tune done.

Where did you have your turbo rebuilt? Are there any options for us to maybe upgrade to a larger 16g wheel? I'm still digging into this EJ20G stuff and really impressed with this engine thus far and want to get the most out of it as reliably as possible, not really needing more than 300HP.

I did the same thing, putting pieces together for the 550 took me a year. Considering it's only $45 dollars for a retune, I would just get the 440 for now since you don't have a US gas tune. I think you could drop this in pretty easy and save some money on 110 then upgrade later when you've got the fuel rails and everything together for the 550.

I watched some youtube videos and DIYs and did the rebuild myself. Need to mark the nut, wheel, and stud to get it lined back up correctly.

Problem with changing wheels:
1. Tune supports the 16g wheel which can max out the MAF as it is, so not much need for increased flow. I would like a billet small 16g wheel for better spool but no one makes small 16g wheels.
2. My intake fits really well with the stock 90 degree elbow on the TD05 compressor housing. Modding rubber elbows to fit other compressor housings hasn't worked well for me and getting a turbo shop to machine the stock housing costs money.

I have a couple sets of EJ25D fuel rails laying around. I just need to track down a set of 550's really. Need to weigh the cost of buying new or buying used and having them cleaned. I didn't realize that he would give such a large break on a retune. I'll have to look into that. For now I'm trying to catch up on some maintenance items. Rallycross has been wearing on the car. Been replacing bushings lately doing a little at a time. My MAF just died last weekend and My radiator just sprung a leak so I'll need one of those soon and I think we have a night rally coming up so I need to grab some fog lights and fab up some brackets. Money for the tune is on the back burner at the moment.

I do highly recommend a nice aluminum double core. I got a cheap ebay no name one, and it has held up great over the last year and really sheds some heat.

That is what I am running already. It's a legacy ss koyo or Mishimoto from what it looks like and I found an old thread where they had a bad batch with a leak in the same spot. I'll be picking up a koyo soon. I run a pressure less cooling system so it's barely seeping at the moment. Not even dripping. Just started smelling some coolant when the fans would Come on.

On Thursday I finally got my 6MT and all that good stuff in the car(93 WRX EJ20G). I also got a set of 05 STi 550s and Rob's new 550 tune in her too. All I have to say is amazing. The car has never felt better. I had Rob set my rev limiter to 7800rpm(can be set to what you want) and also added his new Launch control feature. The car is running 15psi in lower gears and hitting about 17psi in 4th through 6th tapering to about 15psi by about 7500rpm. There is still a little more to be had, but for now I will keep it at this level for a bit. Car pulls strong right to 7500. Launch Control is just too much fun. It revs to 5000rpm in 1st(can be set to whatever you want) and builds just under 10psi at the line. The car actually spun all 4 RE070s today. After a couple of tries I got the car to hammer out of the hole just perfect.

I would recommend this to anyone looking for a great option instead of a standalone. This tune is pretty much as much as you want to push out of your stock engine and still keep it reliable anyways.

I would also like to mention that Rob provided get tech and just general support to me. Shipping was very quick and he will work with you to get what you want.

Cheers, Ryan


How did you activate the launch control my robs 550 tune I have no idea how to work it

The defrost button, if I'm not mistaken? Check his website.
