The "Let's upgrade Jeff NJ's car" thread

So I am loving my 930 in its stock form, but I always knew I would fall prey to the mod bug, so I want to start putting together a build list of sorts and ask for input from all the experts here with all the vast knowledge you guys have acquired.

My car is an 88, 58k miles and is totally stock. Original Cali emissions, 3ldz turbo, OEM IC, etc. Clutch is replaced, but not sure what it is. Gotta look at the receipts that came with the car. I want to keep the upgrades to basically bolt ons, so if I ever sell, there is still the choice to return to stock or keep the upgrades. Certainly a debatable choice, but that is where my mind is at the moment. (I know, I know, it will probably change later and you can all say you told me so then!)

The goal is earlier and quicker spool up and more power across the RPM range without sacrificing everyday drivability or reliability. I am not going to EFI. I do not have a BL WUR (tough to find now). I am getting historic plates, which in NJ means no emissions testing.

Here is what I am thinking:

Rarlyl8 headers and muffler with cat delete.
GT35 turbo
Tial WG with 1.0 bar spring
inter-cooler (not sure what yet)
MSD and coil.
AFR and boost gauge in the dash (PLX or similar)
CIS upgrades? not sure what I can or should do here. At what point does CIS cause problems due to not enough fuel?

This is probably a fall project, since I don't want to have the car in parts during the spring and summer and I just got the car in November, so driving it is more important now.

I will keep this thread updated as I build it for future reference to anyone else doing something similar. I want to dyno it before and after too, so I have actual proof of the improvements (or problems).

What say the experts? What am I missing? Any suggestions for a better combination of parts to get a good package together?
Happy to hear any and all opinions!

Since no post is good without pics, here she is freshly lowered (24.5-24.75 all around), and new RE-11's mounted.

Jeff, some of your listed mods (turbo and 1 bar w/g spring for example) will mean that you will have to increase/alter fueling (aka: CIS mods). This would be easily done with an adjustable WUR/CPR, but unfortunately, no one is currently making those and they sell almost instantly when used ones come up (as you noted). I can't say what your options are other than to watch eBay and the PP classifieds like a rabid hawk!

The need for increased fueling with the above two mods is . . . the GT35 turbo will still be blowing hard (like Paul) at the top of the RPM range whereas the 3ldz is long out of breath by then, and the 1 bar spring increases the engine's effective compression ratio (and creates more intake heat) than the stocker, so more fuel is needed to lesson the possibility of detonation.

By the way, "keeping it stock" is for posers and pantywaists (except for installing 18" wheels as that's just gay)!

Ronnie, I have been looking for a BL WUR with no luck yet.

If I don't find one, is that too big a turbo? Maybe a k27? Any other way to get enough fuel? Do I have any idea what I am talking about??

The primary reason for upgrading is so I am not a poser or pantywaist! I'm keeping the 16" Fuchs on the car until I can't buy tires for them...

Jeff, I can't intelligently answer the question about the turbo size - no doubt someone like Chris of TuboKraft, or Brian, will chime in on that - my comment about the turbo is that it is easy to run out of fuel at high RPM with a more powerful turbo (most any out there when compared to the 3ldz) and stock K-Jet/CIS settings (control pressures - particularly full throttle enrichment control pressure).

I saw you have plans for an onboard AFR meter, so at least you can monitor what is happening as you make mods.

I don't know of a way to DIY increase/decrease control pressures ("fine tune" style) without an adjustable WUR . . . I know that Brian (RarlyL8) has said that one can send their WUR to him, with instructions on where to set the various control pressures, and he will do it, but wow, that seems like a last ditch effort and you would have to have a lot of knowledge/experience about the relationship of control pressures to exhaust AFR and so forth - so much easier to do, real time, with an adjustable WUR and AFR meter. It really is a shame that Leask is not doing them anymore.

PS - Jeff, let me know it that gif is offensive to you, or you simply don't want it stinking up your thread, and I will remove it and save my Paul pokes for his threads!

The mods you list were essentially my "round 1" of mods. What you describe would be transformative to the car as it drives now. To be honest, you can keep your stock parts but I assure you that you will never want to go back to them...

I would encourage you to speak with Chris @ TK. He is a very honest guy and won't try to sell you parts you don't need. He will shoot you straight.

The two things I would add to your list would be:

1) Upgrade both fuel pumps to Bosch 044's (Chris @ TK has the fittings to make this PnP) and do the fuel pump relay mod ASAP

2) WEVO shifter

Your initial list of items is great and you'll have a ball-buster fun time with the car afterward. It will be straight giggle time when you hit the gas!

Kind regards,

Chris.

What does an adjustable WUR look like? i may have one of them spare

Your car will be more fun to drive for sure with these mods, and you should most definitely get with Chris at TurboKraft. I have his intercooler on my car, amongst other things, and it looks great(anodized black for the semi-stock look), and performs great as well.
As far as the turbo is concerned, if you run good headers, the k27-7200 is terrific, spools up quick, and is a direct bolt on with no fitment issues. The WUR is your biggest problem, does anyone know what happened to Mr. Leask? I sent mine to him 9 months or so ago for a rebuild and to make it adjustable. All of a sudden he's totally off the grid?
Your car will be a ball of fun to drive though, but as the graphic above states... once it's starts, it doesn't stop...

Definitely going to speak with Chris and Brian before I spend a dime.

I have no intention of going back to stock. With the market going up, I just think keeping the ability to go back may help in the future. Maybe not. Who knows. At least it will limit how much I can spend on upgrades!


What is the "fuel pump relay mod"? Can someone point me in the right direction to some posts about it?

The Wevo shifter is already on the list to be done before I do anything to the engine. In fact, I just got the PSJ installed last night (boy was the old one shot) and a certain member may be selling his slightly used shifter and offered to let me know if he liked the replacement and was willing to part with it!

Thanks Chris!

I have a few mods and it transformed the car. You will certainly not look back.
A stock 930 is kinda slow IMO.

Great looking car.

Looking for a WUR also.

The line for a BL WUR starts right behind me!

Every time I punch in TurboKrafts number into my phone I think of this:



In the last month I have almost hit the dial button 4 times before I recovered my sanity.

There seems to be demand for the BL WUR, maybe he'll open up for business again sometime in the near future... Your car is beautiful btw! Good luck!

Your car is to nice to be touched...Its going to cost you a lot of $$$$$$ like spanky- says above.. leave it alone...If not, sell it for top dollar

Get a GT3RS or 997TT-Chip & Exhuast. (jmonp)

See posts #2 and #4 - Jeff is safeguarding both his manhood and his car-enthusiast-hood by going down the mod path - pity you want him to do otherwise!
