replacing odds and ends

If you are still looking at getting vacuum hose, give this company a look:

I ordered some vacuum hose / coolant hose last summer. Shipping for me (I'm in Canada) was reasonable. Good product as well

I shall give them a peak. But car isnt get any more hard parts.. I keep getting metal flakes in the oil!! Dx aahhhhh time to save up for a jdm NA and rebuild. High comp, forged, cammed, bigbore tb, new bumpers and fenders (all jdm).

[z.Leinbach]

So i was under my car today and i noticed a dent in the oil pan that was towords thr front of the car. Looked.. Now i say looked like a about maybe a 1/2 inch inward and about 1.5inch ovally shaped dent. Just curious if something like this could cause oil starvation? Which could mean for the metal shavings in my oil.? Or if bearings in a water pump that are grinding itself into oblivion on the inside could cause metal shavings in my oil? If the dent was enough to cause that... Can the dent be pulled with out removing the oil pan? Because i dont frankly poses the means to pull the pan and fix it. Cause might aswell do a refresh while its out.

[z.Leinbach]

Well i contacted Mad Zyientist Motorsports down in Florida, and ran the situation of the last few months and oil changes by them, prognosis.. Rod bearing.. Welp I'm going to overachieve and replace main and rod bearings, new oil pump/pickup and pan.

You may want to do more than that, by that I mean do a COMPLETE diagnosis of your block's condition (compression leakdown test, boost testing for vac leaks, electrical, etc.) and with your refresh comment in mind...be ready to do so. I guarantee the seals all need replacing as both of mine have needed, and while at that do all the main connectors as I did in both (remember, I showed you that your connectors are definitely corroded) and while doing that, do injector connectors at minimum and yeah, best time to do the dreaded injector job they all need unless it's been done...you know how it goes, and it will trust me. The VG30DE is a crispy critter after all this time, and when that's all been fixed you may be a bit less excited for upgrades because you'll be surprised at how much performance was missing and now is back...or at minimum you'll be happier with her while you save for performance stuff.
Boring stuff I know, but actually THE most important work you can do for your Z32 and really needs to be in place BEFORE any modifications at all are done.

[z.Leinbach]

Ohh no worries, I'm getting a whole new engine harness. And I've decided for cost wise. I'm going to just buy a block and rebuild that one. And up the compression a wee bit and add some cams and adjustable exhaust gears. Maybe go to the next injector size for support..

[DCaff300ZX]

Sounds like a wise choice, that way you get more control of your final result and not at the loss of your vehicle in the meantime.

[z.Leinbach]

I do occasionally make such choices haha. I wont be doing a wire tuck though or shaving it. But will ne cleaning up a whole bunch of the bay and may repaint. it

[z.Leinbach]

Well. A new problem has occured. The car wont come down off of the car not wanting to come off of fast idle? Doesnt idle below 1200 warm. But idles at 1000 when cold. My gas mileage hasnt really changed. But its doing something not normal. Sooo wtf, and fml another problem

[DCaff300ZX]

IACV...

[z.Leinbach]

That much i figured. And other then spending 370 ish for a brand new one. How do i fix it? Cause i did narrow it down to that.

[DCaff300ZX]

Unfortunately fixing it usually is not possible, and new is the only positive result. I tried multiple cleanings on my previous one, VERY anal cleaning I might add after the first time cleaning didn't help. Later inquiries into the situation indicated that new was the best repair given the gunked-up insides really can't be cleaned adequately in most cases, and a "good used" one from Z1 made that opinion fact as it worked no better than the previous even after it's own cleaning run, and so I was forced to then purchase a brand new one which did work perfectly.
I also bought their updated harness which has shielded connectors, well worth the $.

[z.Leinbach]

Well as for the idle problem i have finally tracked that b*tch of a problem down to the air regulator. Buuut needless to say. Still gonna take extra care of the whole top end while I'm at it (minus headgaskets..) Is there anything i need to be aware of when i take it all apart? Because i will be replacing the injectors. (Finally) i thought about TT size injectors but can't afford a new ecu along with it because i want a new clutch to completely seal up the engine.

[DCaff300ZX]

That's good to hear Zach, you will be happy with the results of your efforts. I hear ya with the IACV/air mixing BS, that area is a real headache and my least-favorite Z32 engineering nightmare...well, other than dealing with the turbos.
You thought correctly with the injectors, you'd need to get into tuning to make it all work and not be it's own problem on the stock ECU setup. As for clutch I was talked into a organic upgraded Exedy clutch pad in conjunction with my upgraded pressure plate, and am happy I junked the 6-puck clutch I'd bought as the Exedy is awesome. Grabs hard when needed but engages really nice, same even better to my style than OEM.
Otherwise just be sure to buy good OEM or known better components from our better distributors, and enjoy the fact you shouldn't have to worry about those items again, or for a very long time. Buy the upgraded harnesses as they are waterproof now, and like the EGR often have other upgrading to know weaknesses. I also sprung for the kevlar racing tb (plus Ramey Z studs, shifter kit, chromoly pivot and upgraded shift fork, etc.) in a black Friday sale along with nearly everything else in my own upgrade, look for those sales to make your purchases to save $, but still get great stuff. The brake booster brace is a great cheap upgrade, the voltage always-on mod and other similar stuff are also good ideas when you have everything apart, look for those types of things as well as the obvious stuff as it all adds up with the Z32- that's what Nissan was going for with all of their over-engineering so it's wise to keep that idea going if at all possible.
When you get going and if in question about some other part or upgrade, ask away!

[z.Leinbach]

Well im mainly doing the top end at this time. So all seals. But am not taking the heads off. I dont think,
But will be fulling cleaning it and with the injectors ill be getting the deatschworks injectors and plug and play pigs. And would there be any power gaining bumping up injector sizes?

[z.Leinbach]

Well i thought about the robz 62mm TBs but thought again.. Lol not enough gain for it. But ineill for sure be doing all new sensors and regulator/dampener, hoses, vac lines, aiv delete, i think, havent decided yet. Lol and all new clutch setup and solid brace and short shifter.. 3100 later.. Fml havent hit purchase yet. But that's painful. Full amount of parts purchase date to current (2k) now adding 3100.. And havent event touched suspension or brakes yet..

[DCaff300ZX]

Heh heh...yep, I learned to not keep a full eye on the monies spent total as it starts to argue against things on the realistic end, which is what we are avoiding with our projects that make no fiscal sense...
I think that injector changes would not work well without supporting mods (ECU, TB's, exhaust flow increase) and should be part of a complete plan to implement them correctly, like any other more major engine mod. The NA isn't like the TT building it, since the gains are very minimal across the board and always more expensive than you'd like for that gain...why most don't go too far with an NA. I think that your final plan sounds like the best for now- get everything up to snuff with a few choice upgrades while doing so, and add more carefully later as fits your budget and life. You may find as I did that the NA is best for daily, and find a deal on a TT you can mess with for that "fun" Z32 project that will net you something very fun and worthwhile for the time and monies you spend. $3.1K to have the NA in great mechanical shape for awhile isn't too bad, and would allow you to think about that project TT.

[z.Leinbach]

Well ive been reading around and thr uograded throttle bodies dont actually offer anything accept a boggy low end. Which is where i want my power, low to mid.. And if i did do the next size up injectors.. I would be getting a new ecu with the proper tune to support the bigger size also i full hard pipe intake and wont go dual till i get ported and cammed heads. But the shopping list does include headers. For the exhaust flow and i would get some new test pipes made to match the flange and tapper down to 2.5in. Id like to keep some sembleance of mpgs haha. This will be a tried and true GT car

[z.Leinbach]

Wellp i got a whole new gauge cluster, and Headers!!! Im soo excited! Now question what size is the down pipe on a NA car? Im going to have some test pipes made and im going to be keeping both flanges to the headers and to the cat back, and i want to size match for optimum flow. Help?

[z.Leinbach]

Well i am picking up new idlers, belt, jdm knob(miss the leather), some washer check valves, indicator pig tails for the front, and new adjustable powertrix tension rods.. Next paycheck, upper and lower control arms for the front.. After that fully adjustable rear end install my diff bushings and maybe some solid subframe bushings.. Then sway bars and braces. And so one

[z.Leinbach]

Well to update this not as much has gotten done, buut i have not installed the headers, or the new gauge cluster as it was a 93 model robbed the good bits out of it and tossed it, but have all new 02s, fuel regulator, dampener, filter, coolant temp sensors and plugs, and iacv, fast idle plugs (iacv and regulator is next), also have yet to install my diff bushings. But oh well.

Main update with the car, i am going to turn it in to a NA-TT car. Yes turbos on the factory NA. Zshack provides eproms, but ive been talking to some guys on Facebook that have them and they daily theirs with no problems making factory boost levels, seems more viable for the quest for boost then a pta swap
