Very nice! Can you share your virtual dyno settings?

He offered to tune it that way but I opted for ALL of the boost in every gear :tup: On the pump gas tune it's not so bad.

Obviously you'll have to alter the weight and tire diameter to suit your setup, and possibly add 5th gear? I have NO way of doing a 5th gear run on this island so I never added it.

Well it was a fun day of racing on sunday. I am horrible at drag racing also it would seem. Trying to slip the clutch properly was proving difficult and I need to shift quite a bit faster, more seat time is definitely required.

The setup was as follows:
245/40R19 tires on stock 19x9 sport wheels
275/50R17 M&H drag radials on 17x9 R33 wheels
Fortune Auto 500 coilovers 10k front and 12k rear rates with damping at full soft
Hotchkis sway bars still connected all around
OS giken GT street twin plate
Running the ethanol tune so max effort from the motor

For some reason I was getting wheel spin even at 11psi in the radials.

Please don't judge the car on my poor performance as a driver :rofl2:

The plan is to do the following for the next event:
Raise the car up an inch and get it re-aligned
Possibly swap out the springs to 8k front and 10k rear (down from 10/12)
Disconnect the front sway bar
M&H bias ply front runner tires to swap on to a pair of stock spare 18x4 wheels
Hoosier 28x10r17 bias ply slicks to mount on the R33 wheels

I am sure with those changes and practice I will get a decent 60ft and be in the 7's consistently and see if I can work my way lower.

Since I raised the base fuel pressure the pump gas tune needed reviewing. I gotta say I've never had someone put so much effort into a tune for me yet. All of the fail safes are there should something go amiss, driveability is smooth and the power delivery controlled and non-violent for such a quick spooling setup.

Ill start getting the parts to fix the built motor next month probably. I need to decide what I am doing turbo wise because the stock ones wont be going back on.

Well I think it's safe to say these were the original brake pads and I feel so ashamed that I never checked them out sooner.

http://www.the370z.com/members/sirni...1645182127.jpg
I got Powerstop track day pads since Rockauto saw fit to stop carrying the Centric/Stoptech performance pads. I am pretty impressed, they came with new sliding pins, clips and grease, although I reused the stock pins after wire wheeling them because they were shorter than the replacement pins and I didn't want to see them poking out of the caliper.

http://www.the370z.com/members/sirni...6918084749.jpg
That's one of the rear pads, I didn't get a pic of the front pads but they were at around 3mm left.

I swapped in stoptech rear braided lines and bled the system with Motul 600.
After bedding them in as per instruction I am pretty pleased so far, nice bite when cold and no noise. I noticed quite a bit of dust after the bedding procedure so will keep an eye on that but I can't expect them to not be at least a little dusty given their intended use.

I LOVE flex fuel. So much easier than having to drain your tank or running out of gas.

That being said I will probably let it run out of gas the next time, 15 gallons of x98 and I ended up with 78% ethanol content. Gonna try and get it to the point where I'm only spending on a 5 gallon pail, maybe 2 to get the content above 70%.

Husam has it set that the boost along with the timing goes up from 12psi to 14psi past a certain ethanol content. With the weather being unseasonably cool for down here (high 60s at night) the past few days I can't wait to see what that does for the ethanol tune 3rd gear virtual dyno pull I'm gonna do later.

Hit the drag strip again today and with ALOT of help from my friends and keyboard magic from Husam I did some personal bests.

http://www.the370z.com/members/sirni...5748251750.jpg
Unfortunately there was no MPH in that lane (gardener weed wacked the cable), I was running in the 96mph range when I made other passes. Side note on that time slip I didn't get beat by a stock M4 with an E85 tune.

http://www.the370z.com/members/sirni...-40-23-pm.jpeg
Tire setup changed to 17x9.5 Forgestar F14's with M&H 28x10 bias ply slicks in the back and OEM doughnuts in the front (I know I know) the proper tires will be here in 2 weeks.

Again I can't thank Husam from BTWTuning enough for all the effort he has been putting into getting the most power we can safely out of the car. The car is an ANIMAL on ethanol.

Next month I am looking forward to more seat time and with the proper front tires and 8k rear springs, getting a better 60ft.

I'm hopeful we can increase that power on E85 and shoot for 6.9 next time :)

It's been a pleasure tuning your car, you deserve to enjoy it for another 100 years for the bad luck you've dealt with last year.

My race against that M4. That thing is scary fast for only having an e85 reflash

You guys getting bounced around from earthquakes?

All that is over thankfully. We’ve had tremors before but nothing like that! No real building damage but lots of sink holes because the soil is so sandy. Schools are out today, so glad to be home and not at work dealing with the drama over a little shake up.

Since I made my own intercooler setup horizontal, most of the top of the core was blocked. I do plan on redoing it with a vertical setup but until then.

http://www.the370z.com/members/sirni...-01-22-pm.jpeg
I cut the bumper opening a bit.

Well I have a few updates in regards to the built motor and old turbos.

Engine wise I have ordered a single eagle rod, main bearings, thrust bearings, 2 sets of rings (only changing the rings on the one piston, got extra in case i break one). King has finally released the correct connecting rod bearing part number but it's not in stock at summit yet (Part number CR6902XP)

I still need to order an oem gasket kit and a crank.

Upon reviewing my emails with FP and confirming with a caliper on the good turbo, the CHRA were GT28RS. This means the turbine housing is machined and modified to take anything from a GT28 to a Gen2 GTX2876. ATPturbo has the GT2871R super cores for $948 and if i get them with the Nissan 2 bolt inlet, 3 bolt outlet compressor housing, I will only need to modify the hot pipes slightly.

I don't want to end up with headgasket issues so I plan on staying under the 800whp mark and since the plain old GT2871R will do that, I don't see the need to spend an extra $1k to get the GTX version.

Got the FP modded turbine housing/exhaust manifolds cerakoted

http://www.the370z.com/members/sirni...-02-01-pm.jpeg

I'm gonna have to do the heat shields now too so they match.

Well it’s race day tomorrow!

The car is currently getting an alignment with 300lbs of weight in the trunk. The first test we got 0 camber at full squat but with 2.2* toe In, so we’re trying to see what camber we can get with 0 toe. I’m hoping I can get in the 1.4-1.5 60ft range with this (I know 1.4x’s is asking a lot).

Will report back tomorrow with the results.

http://www.the370z.com/members/sirni...e7a47869a.jpeg
It’s going down in a few!

http://www.the370z.com/members/sirni...2c12b9d18.jpeg
Best run so far

Well it looks like that’s the best I’ve got currently. Plan of action for the end of March is to fix the built motor and slap on some GT2871R turbos. That is not a whole lot of time, we will see if I can make it happen

http://www.the370z.com/members/sirni...ffc73a6fd.jpeg
Really really liked this shot of the car in the sunset. Gonna get it printed on canvas

Things that are ordered/on their way to the freight forwarder
OEM rod bearings
OEM head & timing cover gaskets
OEM crank
ID1300x injectors
CJM twin pump hanger
Walbro 535 pump
New intercooler hotside material

I am HOPING to have the turbo's ordered tomorrow.

Welp!

Sponsor offered to get the difference so GTX2871R’s it is!

Got back from Miami with everything. Managed to injure my neck/upper back a week ago so I got enough Aleve and Biofreeze from Target to get through this coming week's metric **** ton of work.

http://www.the370z.com/members/sirni...c0a37be63.jpeg
Round 4!

The bearing material scored the cam journals a bit. Took 400-2000 grit to everything and took down any high spots. Other than that I found out that AAM actually bored the motor to 96mm.

I should be able to get the car on the lift Wednesday night to start pulling the other motor out.

http://www.the370z.com/members/sirni...9-13-55-02.jpg

Turbo's are here and I test fit one in the turbofold. I'll get them bolted in tonight and work on the actuator mounting solution

http://www.the370z.com/members/sirni...0-09-00-19.jpg
With the orientation in the ball park I've made one actuator mount. I will need to tweak this for sure.

Yesterday was pretty productive. I got the car in the air, wiring harness disconnected, drive shaft out, fluids drained and front suspension disconnected.

Swapped the ported lower intake manifold, CJM rails and ID1300's onto the built motor.

http://www.the370z.com/members/sirni...20213760-n.jpg
Finished the other actuator mount as well

Tonight I get the motor on the ground and then tomorrow I'll start swapping the things I need to onto the built motor.

Mission accomplished, motor and trans are out and separated.

Today I hope to get the built motor in the subframe so I can finish the intercooler piping.

http://www.the370z.com/members/sirni...73cd85338.jpeg
They do look right at home with the s13/14 style compressor housing

Ha! What an optimist I was. I am dead tired but got a lot done.

The compressor outlets on these end up in very different spots so it was quite a bit of work to get everything pointed where it needs to be.

http://www.the370z.com/members/sirni...8eaf4b1a9.jpeg
Passenger side ended up being one piece, no boost leaks here!

http://www.the370z.com/members/sirni...8185c4862.jpeg
On the driver side I was unable to use the adapter flanges and had to cheat the 90* elbow to weld directly to the compressor, as such there is one coupler.

Tomorrow night I’ll finish weld the drivers side intercooler piping, reclock and reweld the intakes and finish up the plumbing, the block coolant port on the passenger side is going to need a “new” adapter that’s 90* to clear the compressor housing.

Finish welded the drivers side piping & re-clocking the intakes.

Finalized the actuator brackets.

Got the clutch and flywheel back on.

I am waiting for the machine shop to cut down a new bolt that I broke and then I can finally assemble everything and lower the car down onto the motor.

Aaaaand the machine shops are closed.

Who needs em when I have frustration fueled patience and access to a drill press and a file :rofl2:

http://www.the370z.com/members/sirni...-39-37-am.jpeg
It's in! Was a solid 6-7 hours of work to get everything bolted in.

Check list
1) Make some small adjustments to the hot side intercooler piping which was expected
2) Extend one of the intakes
3) Install injector harness, upper intake manifold & cold side piping
4) Install bumper & head lights
5) Install shifter
6) Fluids
7) Flash basemap from Husam
8) Vacuum & recharge AC

Wife says I'm not allowed to go work on it today so I'll have to finish up in the nights this week.

Side note for anyone considering the GTR turbo conversion with upgraded turbos, stick with the stock compressor housings, the S13/14 style compressor housings barely made it.

http://www.the370z.com/members/sirni...94846208-n.jpg
Drivers side clearance

http://www.the370z.com/members/sirni...77610752-n.jpg
Passenger side clearance. It look's like it's touching the frame but it's not.

It lives! I forgot I only got 8 quarts of oil and proceeded to drain it after warm up. Some dust on the oil drain magnet but nothing to be alarmed about.

Tomorrow I’ll fill it up and go datalogging.

Filled it back up this morning but spotted a small leak. The oil pressure sensor port threads got stripped, that's what I use to feed the stock oil and Innovate oil pressure sensors. So I welded a 4an bung over the hole, seems I left a pin hole.

I'll clean it up and luckily the torch head can get in there to fix it.

Once that's done I need to wire in the head phone amp I got off amazon to the knock sensor using the uprev instructions.
https://uprev.com/documentation/Knoc...n%20Device.pdf
https://www.amazon.com/Neoteck-Headp..._dp&th=1&psc=1

Finished it all up and drove it home. Big turbo life is different, the difference in spool is very apparent but it was 57% tps and this is just a base map with very conservative timing.

Very excited to see what we can manage to extract from the car in the days to follow.

Well reusing that cracked manifold that I had repaired has bitten me in the ***. The crack has opened back up so I'll be parking the car for a bit while I locate a drivers side turbo and get the exhaust manifold to FP to machine for the GT28 turbine wheel. I am not too bummed since by the time I locate one and it manages to arrive here in the current situation, my garage will be finished and I can do the swap at home! Pop this Danmar M6 lift's (I've had in the spare bedroom since october) cherry the right way.

Also since I have nothing else to do on the car, I wired in the knock sensor earphone jack.

speaking of

http://www.the370z.com/members/sirni...4-08-15-10.jpg

Given what's going on, the final inspection for the belting is SUPPOSED to happen monday. The trusses for the roof are scheduled for delivery next weekend

Well not much to report. I have a garage now so I can finally work on the car at home. Still waiting on my roll up door to arrive but for now it's functional and comfortable with a 24" oscillating fan. I have a 2 ton split unit installed and working so it will be REAL nice when I can avoid sweating to death.

Car wise. **** this car. It turns into a straight 3 at 6500rpm for some reason.

Wastegate pressure ~12psi on these GTX2871R's is a hoot up to that point. I can't wait for Husam to crank the boost to 16-18psi and get the boost coming in sooner. Once I can figure out what's going on we are shooting for 650whp on pump and 800whp (keeping tq as close to 600wtq as possible) on ethanol.

The company I work for has purchased the 1/8th mile drag strip so there is an actual future for it now.

After the car is fixed I'm setting myself a 1.6 sec 60ft goal on the current suspension and tire setup. Once I can do that consistently it's 350z base brakes, Forgestar 15x10's, 28x10.5 slicks, BC ER dual adjustable coilovers valved for 8k front 6k rear and a Z1 toe arm. Seem's like a lot to get a 10th off the 60ft but in the 1/8th it's no real room to track anyone down up top.

So while figuring out that ******** I took mental breaks from that by installing the awesome CJM dual pump hanger.

I am using a Walbro 535 as the primary since it has no check valve and a 525 secondary. Both pumps have the Holley hydramat socks on them so I shouldn't run into fuel starvation issues

http://www.the370z.com/members/sirni...-42-00-pm.jpeg
I realized this was overkill after but it's there to stay. 6ga wire with a 50amp circuit breaker feeding the 2 relays. Bolted them to the underside of the shelf above the fuel pump access panel.

http://www.the370z.com/members/sirni...bc9d562856.jpg
4psi hobbs switch that I'm hoping I can adjust to 10psi for the secondary pump

Sexy dual pump hanger fresh outta the box from Fedex
