[Anyone running NGK Iridium plugs]

tickwon, The NGK BPR7ES-11 is a colder plug than the BPR6ES-11. I have always been told that a high boost Z will like colder plugs not hotter.

 

As for ordering, I assume I could just special order from my local car parts store.

 

Thanks for the feedback on the Iridium's. Anyone else?

[Anyone running NGK Iridium plugs]

From feedback I read on a previous post I've decided to try NGK heat range "7" sparkplugs.

 

Does anyone have experience using NGK's Iridium plugs?

 

I was considering the platinum BPR7EVX-11 until I saw the Iridium's.

 

 

Thoughts?

[Dual Port Waste Gate Actuator?]

As usual, thank you Scottie for your thorough reply. I am going to run a Blitz Dual SBC Type R controller with my dual port setup to go over 12psi. I'd rather do that than adjust the spring tension on the diaphram.

[Dual Port Waste Gate Actuator?]

That's how I understand it exactly. Basically it's suppose to do a better job of keeping the WG from bleeding exhaust until the boost controller allows it to open.

[spec clutches, price is right.]

The Spec model I bought is a SN323. It has a sprung 6-puck disk. I'm going to be using an Assco 240mm aluminum flywheel. The whole setup should be running in late August.

Tim, I sent $ to the above PayPal for Al.

[280zx turbo swap---driveshaft length]

You need to measure from the pinion flange on the diff to the center of the front ujoint. By center I don't mean the middle of the cross, but the center of the end caps. Make sure you pull the yoke out of the trans 3/4" before measuring.

 

Rumor has it that about an 1" needs to be cut of the T-5 driveline to fit in an S30 car. You should measure to be sure.

[spec clutches, price is right.]

I am installing the same Spec clutch in my Z. Unfortunately they require a 400 mile break-in period before you can put any real power to it. Oh well. I'll play be the rules if it means it won't slip under 20 PSI of boost.

[Optimal shifting for a turbo Z?]

Hypothetically if peak torque was at 4500RPM and peak HP was at 6500RPM where should you shift? I've also had difficulty understanding this question when transmission gear ratios are factored in.

 

Typically when drag racing I shift a couple hundred RPM above my peak HP so it drops back into the powerband.

[Dual Port Waste Gate Actuator?]

Speeder or anyone, I'm about to install my new Turbonetics dual port wastegate actuator and was wondering what the default boost level is. For example, if I didn't run a boost controller what PSI would the wastegate open? My stock Nissan unit opened about 6PSI.

 

Thanks

[What type of driveshaft are you T-5 users running???]

Well as it turns out my new driveline isn't what I expected. When I took it in they said they could find a T-5 yoke and Neapco flange that would work with the Spicer 1310 u-joints. WRONG.... What I ended up with was a driveline with new yoke and new Neapco flange that matches my larger R200 LSD pinion flange. They had to use Nissan style u-joints. The total cost was 279.64. Ugggg!! Oh well. I doubt if I'd ever break it.

Al, Sorry to hear about your son. Our thoughts are with you and your family. I hope someday we can meet at PIR again when you have another Z. Best of luck to you.

[C4 tranny swap for L28 (PICS)]

My Dad runs a C4 with a trans-brake in his 427FE 69 Mach1 Mustang. It run's low 9's on 11.5 slicks and still has a full interior. So far it's held together. FWIW, the C4 is worth about .3 sec in the 1/4 mile over a C6.

[What type of driveshaft are you T-5 users running???]

You're right. I won't be launching as hard as you. WOW!

 

I'll let everyone know how things turn out with the new driveshaft.

 

What transmission do you run to hold that kind of launch?

[What type of driveshaft are you T-5 users running???]

JeffP, you are correct about the pinion flange u-joint being able to use a spicer 1310. That's what I am going to use on the rear u-joint. My problem right now is that my driveline shop can't find a yoke for my Datsun T-5 that will support the Spicer 1310. For now it looks like I'll be running a 1310 on the back and a Nissan on the front.

[Majestic Turbo Bullet]

Hi all, I recently called Kevin at Majestic Turbo to discuss upgrading my compressor wheel to a 60-1. He's a heck of nice guy and gave me a decent price for the upgrade. He suggested I also upgrade to their compressor wheel "bullet" nut. This is a aerodynamic nut that secures the compressor wheel to the shaft. Kevin said this improves flow.

 

Is anyone using this bullet nut? Do you think it's worth the expense?

[Bosch LSU-4 and NTK wideband O2 sensors]

Thanks Tim. I should have searched on NTK instead of LSU.

[Bosch LSU-4 and NTK wideband O2 sensors]

Any of you EFI guru's using the newer Bosch LSU4 wideband O2 sensor yet? This sensor and the NTK unit are suppose to be the most accurate available. My Tec3 now supports these sensors, but Electromotive is still in Beta testing.

 

Cheers,

[Convert T04E wheel to 60-1]

Lockjaw, If I remember correctly you have a JWT Sport 450. Correct?

 

Thanks

[Convert T04E wheel to 60-1]

Rick, For me the spacer doesn't present a problem for my IC but for my Scottie downpipe. If I move the turbo out 1/4 inch then I will probably have interference problems in the transmission tunnel. My T-5 is going in now so I'll be able to check the fit soon.

 

Who did the custom work on your turbo?

[Convert T04E wheel to 60-1]

Are you guys running a .60 A/R T04E compressor housing with a spacer?

[Jim Wolf - Sport 450 or 400 turbo owners please read....]

Hi folks, I have always assumed that my JWT Sport 400 used a .60 A/R compressor housing. After closer inspection I noticed mine is a .50 A/R.

 

Is that the size on your JWT turbo also? Assuming the larger .60 A/R would increase the external size of the housing I don't know how it would fit on the L28ET without a spacer. I currently have 1/8" clearance from my exhaust manifold.

 

Thanks,

[Convert T04E wheel to 60-1]

Hi all,

After talking with some folks and reading this forum it seems that the T04B 60-1 wheel would be a better fit for my car. I've heard it's possible, even suggested that the 60-1 wheel be installed in a T04E housing. My turbine is a stage 5/10 blade .63 T3. Can I get a response from people who have done this upgrade? I'm looking for feedback on driving impressions and recomendations for a turbo shop that's done this conversion.

 

Thanks,

[What type of driveshaft are you T-5 users running???]

The pinion flange I'm talking about is the one that came on my 88 300ZXT R200 LSD. The bolts are larger, 10mm I think. It's also a bit thicker. To go this route you will also have to buy the driveline flange that mates up to the larger pinion flange. A good driveline shop should be able to handle this.

[What type of driveshaft are you T-5 users running???]

Coincidentally, today I had my local shop start on my custom driveline. To avoid the "explosion" as you say I am using non-greasable Brute Force or Spicer u-joints. The diff flange is the larger 300ZX version. The whole thing is costing me 325.00. but I don't think I'll ever break it. Some day I hope to put down 400RWHP while visiting the dragstrip.
