Yeah on a short nose 1.6 as stated above. Seems to be about normal for what i've seen dyno wise online. May eventually upgrade to a GT25R but for now the journal bearing has me happy.

BTW 18PSI, my stock clutch is slipped pretty bad so i've been waiting on that to get installed before getting some logs and auto tuning. I drop the car off on friday hoping to have it back next week. Will get back to you soon!

I'm still trying to decide if i want to send the IC piping through the fender to clean up the engine bay a bunch. I really would like to just slap the air filter on the front of the turbo and call it a day instead of the crazy routing i have now.

The air filter wasn't attached in the picture. I'm using a UNI dual foam air filter from that just slaps on the end of the intake tube that sits underneath the hot side IC piping off the turbo. It sits above the coil over basically.

Great stuff. I'm looking to order a kit soon for my MSM. How was the downpipe fitment? any pics? and did you have to hammer any of the lip (behind the turbo by the brake booster) to fit the downpipe or did the forward placement help with this. Thank you.

Subbing to this thread bc i have the same kit.
Im assuming you got the banjo bolts for the water in/out, did you put copper washers or any sealant on them at all?

Have been super busy with work and haven't been able to do much to do the car. Have been driving it and auto tuning it and it's driving very nicely. I turned it up to 10lbs and it feels great. I still need to install my coolant reroute and bend the hard water line thats hitting the DP but my license plate fix is still working funny enough.

The DP fitment is quite good. There's a few MM of room between the rear shelf and the DP without any cutting. You do need to at least slide the DP onto the turbo before bolting the turbo to the manifold otherwise it won't fit on with everything blocking its way. I'll try to grab some pictures later.

Yeah, i got the full kit. I used some copper washers I picked up from autozone and they work great, no leaks.

Oh that must be an early kit before he had the cast turbine outlet. Much more room with the new setups.

Yeah I hopped on the waiting line before anything was really released besides a few test releases. Doesnt matter to me really the fitment is still good enough as is. I don't plan on doing much else to the car really besides maybe having the turbo rebuilt/replacing it when the time comes. It's a fun daily that will probably become a beater thrash car at some point. It's not clean enough for me to want to build the chassis properly, and that is why it was a budget oriented fun daily 1.6.

Oh she hits boost nicely all right! still dialing in the tune a bit but the cars a blast at 10psi out of this baby little turbo.

It started breaking up yesterday after having no issues since the new plugs. I was autotuning at the time but the AFR's were right around 11.8-12 in full boost. So i checked the plugs again and regapped them to see if it clears up.

I'll see if i cant get my buddy to get a video of some pulls i'll be making.. In mexico for datalogs that is!

Now that the weather is finally warming up I'm hoping to tackle the coolant reroute and some minor things before taking it to some autocross this spring and summer.

My main head ache right now is that the car aligns like doody and it won't hold the alignment. I have new alignment bolts on the shelf but haven't had the down time to swap them out.

Another small update. Have been fine tuning the car and going over it with a fine tooth comb now that the weather is pleasant again. I've installed a hawley performance coolant reroute with 180 deg thermostat, found a few wires with sh!tty connections(you were right vlad!), threw in a 190HP fuel pump(was around 80% duty cycle with this turbo and injectors at 10PSI) and am in the process of installing a hard dog roll bar.

trying to get it ready for autox this sunday!

Sorry for the complete and utter lack of updates. Have been dialing in a number of things on the car over the passed few months and just recently finished up putting on a larger turbo along with the timing belt/waterpump and deleting the AC. The turbo i was using prior was a well used one that had a well worn wastegate actuator spring and waay too much wastegate shaft end play. The thing rattled like crazy despite still making good boost so it needed to go. Wanted to go for a BB 2560 but cant spare the cash with all my money being tied up in a house right now so i went for a larger t25 from twistedtuning in vegas. It's basically the same turbo core with a bigger compressor wheel and a larger exhaust housing. Laggier, but more head room and more of the sort of power delivery i was looking for anyway.

Still trying to dial things in so i'm only running around 6psi right now but it already feels faster than 10psi on the smaller turbo.

Go any spool data for old and new?

I'm on the "on ramp" for a Kraken 1.6 and have been eyeballing a brand new 2554 but was considering 2560 first but was advised that the larger would not give as good driving experience with the wee 1.6 airflow.
I'd be interested in seeing the spool difference.

I'm still working on improving the spool. Have been playing with wastegate actuator springs as well as my MBC but i've gotten as much as 5-6lbs at 4k rpm in 4th/5th gear but I have been logging and will get you some updated logs and post them up!

I could see this turbo being difficult to work with in an autox environment since it is definitely a bit laggy(4.5k- rev limiter kind of power), but for a street car its REALLY fun!

Hey, sorry i haven't forgot but i've been trying to make a WG actuator bracket that works and have been trying to dial in the boost. I now have it set around 6-7psi but probably will turn it up a bit.

I need to emphasize that the main problem with my old turbo setup was that the wastegate actuator was an original sr20 one welded to a bracket that worked perfect in the position i happened to need it clocked in from the previous owner. It was convenient so i used it and it must have had 200k miles on it(turbo also burned oil) and the spring was ridiculously lazy, even with a MBC.

The new turbo actually spools a couple hundred RPM sooner it seems now that i'm getting it dialed in a bit more. 1.6 is hilariously disappointing but its a fun daily with this turbo as it gets much better gas mileage and has much more scoot when its actually in boost.


Vlad if you happen to check the log if you pop in here, LMK if anything looks wonky please! Have been so busy havent been able to get many logs.
