Been awhile since I've posted but some pretty significant updates and major issues.

First preparation for Global Time Attack at Ridge Motorsports Park (my home course)

Finally got proper bucket seats and harnesses, Loved my Recaro Speeds but on track the slop between the lower and upper part of the seats was distracting.

Also added the Coolerworx shifter. I always thought the factory shifter felt great and this shifter only added to that thought.

Next installed the entire ensemble (At least the rest of it) of SPL parts.

Also upped the spring rates at the same time to account for the aero.

Do yourself a favor, remove all the arms and have a machine shop press in all of the bushings. It only ran me $200 and saved me a lot of headache.

Best of Luck on the Global Time Attack. Remember "Wall Bad, Finish Line Good." :tup:

I wish I had good luck! Incoming follow-up post

Finally was feeling comfortable enough to participate in Global Time Attack, best of all it was the first time GTA would be at my home track! Had some issues with tech but was eventually allowed out on track on the second session

Unfortunately it was the first time the Z has left me completely stranded too.
On my first session out just 4 laps in the motor blew at the end of the front straight doing 150+ (Code Brown anyone? :eekdance:)Some pictures of the carnage.

Ended up finding 5 or 6 holes in the block after pulling it.

I can't say I was disappointed or depressed about the engine, it took 5 years of 500+ WHP on a virgin block without a problem.

My issue was I was on year old scrub 275 Nexen SUR4G (Excellent tire BTW) instead of the 295 Advan A052's I had waiting to go on the next day. I was holding out better weather on day 2 as it was raining every other session all of Saturday. I was able to manage beating my PB on that 4th lap with a 1:50.775 and was barely settling into the new suspension setup. The lap was Good enough for 4th at the time but after the weekend settled 6th.

Good news is, GTA will be returning to Ridge Motorsports Park in 2021!

That’s impressive the motor lasted 5 years of pounding. You have any idea what the old temps were like? I’m thinking about adding a second oil cooler to keep things cool. I was looking into the g30-900

Yeah I was impressed, I did a leakdown and compression test before this season and the motor was healthy. Old temps I would have the coolant pinned after 2 laps. Oil wasn't far behind.

Just a heads up, G series turbos only come in v-band turbine inlet non divided for whatever reason, you welding a different flange on?

Lord. I hoping the ron Davis Rad and twin oil coolers help with temps. I’m going to have mamotorsports do there magic

Another guy I been talking to is going to install a 2 gallon swirl
Pot to see if that helps with heat soaking issues.

Well after the vent work and relocation my coolant issues were non existent with the factory radiator. One thing to note is the 6266 is not water cooled though.
You can see where I moved the oil cooler in this pic, it's just the 30 row that came with the BP kit. Ducting will be your friend combatting temps!

Exactly where I’m
Moving my oil cooler. Yeah I’m going to duct the front end of the car if my budget allows it. Do you recall your oil temps with the new relocation?

What front bumper is that? Never mind, I found it. It is a Stillen. I thought that is what it was.

You need the Stillen front bumper so you can put your oil coolers outboard. It is not possible with the FI TT kit due to our intakes already being there.

I’ll make the existing bumper work. With the FI kit you can still make it work. Fab work isn’t a big deal with Brian

If my car was a dedicated track car I would do something about it. I haven't had any issues at all doing what I do. I would like to have seen what the oil temps would have done at the Tail of the Dragon at Zdayz but they moved the event. I am not going to the new place. Plus, a turbo car doesn't need to be in the 7k rpm range to make power so you can use a lower gear to get it done.

By the way, it was a challenge to get the brake ducts in. No way an oil cooler would fit. That is why Hotrodz has a 72 row oil cooler.

I think the most I saw was around 240? That was really getting after it though. This newish motor I dropped in I have the OEM cooler and dropped down to a 25 row so we'll see how it handles this time around.

I actually have a new duct that has brake inlets that I need to throw in, fits between the intercooler and the ends of the main inlet.

240* is pretty damn good. That is way in the safe zone. Many racecars run at 260* to 280* without much problem. The issue with our cars is stay with the factory ECU which pulls timing and will put you into limp mode at 265*. Good motor oil which we all run doesn't even start to break down or become an issue until well over 300*. The real issue with heat is water temperature and with oil it is oil pressure. I don't recall ever reading about an engine letting go because of oil temps but because of oil pressure and extreme water temps. My temps are high(260* max) on the most small tracks from a mile to about 1.5 miles which require a lot of shifting, running on the rev limiter and short straight aways that don't allow for good air flow to aid cooling. Oh and then that can be compounded by running in traffic as well. All of those things lead to heat soak which is a performance killer and the over all impact could be catastrophic.

Me and eddie were running 270-280 oil temps last May at Sebring. This is NA with a 72 row. I’m impressed as well with 240 oil temps being boosted

I'd like to think part of my engine temps being low is having the BP kit mid mounted (Aside from the aero/venting/relocation) it keeps the hot turbo outside of the engine bay for the most part. Factory manifolds with factory heat shields, Turbo manifold is jet hot coated and wrapped, turbine housing is coated and wrapped with a blanket also.

I'd say the Trackspec vents made the biggest difference though. Do you guys have hood vents?

Oh yes I do. Tracspec as well. They work like a champ.

LOL, I am the one that talked Trackspec into making them. We did the whole group buy thing and tripled the number we needed.

I found it to be worth about 10*. I think the Stillen front bumper does a good job too.

Oh haha, It was so long ago I forgot. Thanks for the push!

I'm actually thinking the openings for the Stillen bumper are too large. I was planning on making the inlet smaller/making the air dam taller and creating partial block off plates for the side inlets ducting it to the intercooler/radiator kinda similar to what Pro Awesome did to their Evo in here.

It is a constant balance of airflow, downforce and cooling. I have been considering some of the same things.

How did it do?

She did well for some DIY tuning and no seat time since last years GTA!

Down somewhere in the neighborhood of 75-100 WHP cause I took a bunch of timing out for the sake of engine safety and still managed to set a new PB!

Wound up getting 4th in Street Class behind Amir & his NSX, A local J32 swapped S2000 and the brand new M4.



Time for a new transmission now though due to a nasty 5th gear grind.
