Heard good things from South bend and clutch masters.

Did you only install the exedy clutch or did you add flywheel or other things around that? and does it have a light pedal feel?

Exedy makes a LW flywheel, but I'm not a fan of them. Car revs quick enough as it is, and LWFWs tend to decrease load on the motor, which does not help turbo spool. I purchased an OEM flywheel when I did mine. The pedal feel is pretty light yes, it is noticeably stiffer than factory but not by much. It feels maybe 10 percent heavier. A lot of people get hung up on the number, and tend to overlook this clutch because it's "just stage 1".

Seems more people are running the recirculating waste gate verse the dump type is there a difference other than sound?

Recirculating will create a tiny tiny bit more turbo lag. Only something you'd notice in data, I doubt you'd feel the difference. You'd be silly to turn down recirc at the price they're offering. If you go non recirc, it's not the end of the world, but it's more work to switch once you've got everything installed.

The sound is more intense than you hear on YouTube. You need to ride in one, or have one go WOT while you watch and inevitably cover your ears.

My understanding is the opposite: Recirculating should cut down on lag. Pressure spikes as the throttle body closes, diverting gas to the recirculating valve, where said gas is redirected, bypassing the engine and entering the exhaust, keeping your turbo spooled.

For the BOV yes; we are referring to the wastegate, since the JDL kit has an externally wastegated system. If it recirculates back into the exhaust, it's competing with that already heavy traffic. That's my theory anyway, I can't prove it with a whiteboard and Honda S2000.

Ahh, yes. I’m so used to big blocks and super chargers, I completely forgot how much more complicated a turbo setup is.

I opine the internal wastegate would only pose and issue if the exhaust were smaller than 2.5” ID. (I’m ball-parking that as I’ve read 3” ID accommodates much larger turbo systems.)

However, you could always rock a 3” ID exhaust system from the turbo back and likely see no issue.

Yes, a larger exhaust would help. If you're running an internal wastegate, this issue is irrelevant, since the exhaust gas routing happens inside of the turbo exhaust housing and is automatically dumped into the exhaust.

Also, a question of my own; I just noticed they've dropped the PTE turbo in favor of another Garrett; does anyone know the specs of the base model "GT28" turbo they're offering as a replacement for the PTE? Certainly it's not Garrett's new turbo that was released at SEMA..

Alan said in the FB group that it was a journal bearing GT28, definitely not the new G series turbos.

Ok good to know. I was going to buy a kit just for the turbo if that was the case! Haha.

Got around 2000 miles with the kit. Has any of you owners of this kit been getting a constant smell that shows up and goes? Smells at the beginning of driving with the kit?

I've never had a turbo kit before, so I don't quite know what the smells are. The only smells I can distinguish are clutch and coolant. It smells like something is burning maybe.. I have checked for leaks DAILY. I did have a PCV valve leak that I fixed in 1 day. but the smell is still popping in and out. I originally though it was the ceramic coat but now I'm starting to steer away from that.

Anybody?

Are you full catless? Or just header is missing a cat? Were you full stock before? Sometimes with new kits you'll get a burning smell from the header because of the coating and whatnot, but more often then not due to the airflow, you'll smell a lot more smells than before.

Not full cat less, still have stock FP/OP,. I have JDL UEL header now, but when I had the Borla UEL I did get a smell at first but then it eventually disappeared.

I figured after 2 months/ 2000miles that smell would be gone if it was the header or ceramic coat but now I'm starting to worry since it's still present,

Smell isn't permanent but sometimes while or after I accelerate and I don't have to be WOT for it to smell, I mainly stay between 2000-3000

Making progress, but these brackets just don't make sense to me. I can see they are angled out so it appears they would countour the curve of the oem crash beam, however the intercooler is sitting as far back as possible. You can see the charge pipe nearly touching the a/c heat exchange. I'll keep playing with it and see where it goes.




Looking back on page 24, this picture was posted. Brackets are closer together and not sticking out as far. I dunno.

Were you ever able to figure out what the issue was with your intercooler?
