I drove that DD of yours yesterday. AC blasting so cold that my nipples could cut glass :party:

Budget will not cover new shirts :rofl:

Glad you let this one out of the bag. I think your turbo was literally the ONLY EFR that I have not shipped directly to Abe at Artech.

BTW Borg is giving me a real run-around with your EBC. I should forward you the emails, embarrassing really. Telling me "We've already shipped the replacement part to your customer." That would be great, if at any point they asked me for my customers address... :facepalm:

At any rate - If I don't hear something tomorrow I'll buy you a new EBC :makeout:

Thanks for the update! :bigtu: Also, thanks for the offer but like I said, I'm not in a mad rush. No manifold until July so EBC does not do me much good before then.

It uses the inconel valves or it gets the Rotrex again!!

Why does everyone think I hate the Rotrex? Its another tool in the tool box and it performs its function quite well for what it is. Remember that i purchased my kit new and I purchased it for a reason. My problem was never with the Rotrex hardware itself, my problem was with Kraftwerks.

I will admit I was actually looking forward to having an open forum to work over the guy from Kraftwerks. There was blood in the water and I started getting excited again :laugh: I think I got warned/censord on m.net and I got a temp ban on cr the last time I got into this with one of their guys. I just wish the thread here had been around a little longer but I understand that no real good could have possibly come from it.

I bet Scott deleted it, he's such a party pooper :p

I like my Rotrex. I only make the joke because of historical mt.net opinions of it, and the fact that I own one entitles me to make fun of it however I wish :)

Mild or stainless?

Woo! Stainless? What did you use on your NB? I figured I can mooch off your parts list as everything from the midpipe back should be the same :)

I vote stainless for resistance to elements and for shinies!

G I cannot wait for you to make this into a thrust buster and then give me rides. Maybe trade drives for a session. This will involve travel on someones' part (probably mine).

Sure, come on down for Miatas@MRLS this year. Hopefully I'll actually have it running by then :bang:

I'm not super happy with the "traditional" turbo coolant feed line from the front of the engine. I'm blocking the old thermostat neck port with a freeze plug so i cant use it anyway. My M-Tuned reroute has a 1/8" NPT port but its currently occupied by the temp sender for my VEI temp gauge, so that's out. I need to see if I can use one of the ports on the back of the head for coolant source and I'll be a happy camper.

That, or relocate the temp sender. Humm... drill, baby, drill?

So what is the general thoughts from the collective on removing the factory oil preheater/cooler?

I'm already removing the front neck and the 64mm throttle body has no provision for coolant. I don't want to loop a coolant line all the way around the front of the engine to feed the turbo so I'm running out of reasons to keep the factory preheater/cooler chingadera. Unless someone tells me otherwise I'll probably continue down this path.

The port in the above pic looks like it has enough meat to tap for an 1/8NPT and that will be perfect for either the sensor or to use as a coolant source. That will give me 2x 1/8NPT ports to work with (including the one on the M-Tuned reroute neck) so fitting a -6 to 1/8NPT should be cake.

Again, I'm looking for someone to give me a reason not to do this. :party:

do you has oil cooler? if you do, then you'll probably be fine.
just be more careful when warming the car up, cause it will take longer without the oem cooler

I currently haz no oil cooler. I've been waiting for Andrew to put the Mocal Oil Cooler Kit Of The Gods up for sale on his website, but its not something I'm going to run out and purchase immediately.

Super slower warmup is exactly what I'm worried about. I've added a bung to the oil pan for a sender so I'll actually know what the oil temp is, its that whole waiting and patience thing that screws me in the end. Turbo should act as an oil preheater, right?

On NAs, there's a water line on the bottom of the intake manifold, going to the idle valve (which you don't have) and then to the throttle body (which you do have).

Could you steal water from there? I believe on an NB, the routing is:

Back of head -> oil/water cooler -> throttle body -> front water neck -> mixing manifold.

I'm a fan of flipping the mixing manifold, pulling the 1/4" hard line and drilling and tapping there for the turbo water return.

Then you could steal the water for feeding it after the throttle body, or before.

on nb's there is no such nonsense (IM sourced water that is)

*edit: I mean its probably not a huge deal, since early na's didn't even have a cooler, but I'd be real careful when tampering with stuff that directly relates to your engine's long tearm health and wear

I have a VVT motor in my garage, I can take pictures of the routing I mentioned above.

There is no idle valve on the intake manifold, but there is a rear water feed, oil/water cooler, throttle body water lines, and a mixing manifold barb.

Oh I know exactly what its supposed to do:
but also:
Because the front housing has that weird T in it.

But as I stated previously, I'm eliminating like 1/2 of those components. I'm just trying to figure out if its worth deleting the rest of those components thus removing that system all together.

New setup would be:
That's like eleventybajillion less failure points. I'm just trying to figure out if the juice (less fail) is worth the squeeze (no more oil preheater/cooler.)

We all know the reroute is a hack on top of a hack, so I'm just trying to figure out how to clean things up without compromising the system.

I was VERY tempted to do exactly what you're thinking of, but didn't because street car.

Well you're not helping :giggle: Probably because I feel we suffer from the same disease.

Honestly, if this was BECAUSERACECAR I wouldn't think twice about it. But its not, so I will continue to worry and overthink things. I'll probably come up with some solution that is illogical, adds more failure points and is marginal at best. This is usually how my troubleshooting process works. :bang:
