LOL, maybe it's the "affinity" for the 2+2 that makes you a target Tony.

Some of my shots that I had handy... All are copyright so please use them for viewing here only.

2 sets of mikuni 44's in the classifieds now for $650 and $1000. Derek I think you might find it a better plan if you can offer up the raw castings for a fair price and let people do their own machining/design/fitiment. A lot less work on your part too. That's assuming you have any interets in doing all that extra work!

Some goodies from Fedex today... PLX wideband and controller Updated chip on my SDS ECU from v9 to v17 - Wideband data logging - Electric fan relay - Some other minor updates More to come!

$4.03/gallon US... down from $6+/gal this past summer. Don't feel too bad Stony!

Much better! Question: Why use any tubing and not just the wire from the MIG?

Or swap rear ends for the track days.

Did anyone find the complete clip? Interesting!

Awesome build!! Great attention to detail, you've given me a few ideas.

All I've used is Ricardo Wave as well, though it's a *lot* of work to use. Does anyone know if there is L-series info in any of the programs listed above, or are you starting from scratch every time?

Ha!! You'd think so, wouldn't you? At that time I just ended up doing the engine bay. It wasn't until about 4 years later that I actually painted the car, and that was rattlecan at that. I'm still awaiting the "good" paint job. 1st photo is from 2000 when I squirted the engine bay... still blue to this day. 2nd photo is from 2004 when I rattled canned the car... still black to this day. Engine did end up getting cleaned up a lot though. (pic 3)

Nice! What are the specs that go along with this? Nice 60's too.

There is street rubber out there, but your choices are limited. Luckily, when it comes to racing rubber there are lots of choices.

I've got a matching set of two 16x10" and two 16x9" Simmons 3 pc racing wheels that I would part with for the right price... Perfect offset for ZG's and 4x4.5 bolt pattern. PM me if interested.

Ordered a new turbo today... GT3071R! Standard setup, 0.63AR on the turbine side, external waste gate planned as I have an older HKS kicking around I might as well use!

Sadly... not the worst I've seen.

I don't see it mentioned or tested anywhere, so I'll throw it out there. I'd like to see a simple chin splitter added to some of the more common air dams, so see the effects. One that follows the profile of the air dam, extends 1-2" beyond it, and tapers out back to the front crossmember.

Slowly making some progress, doing a lot of research on turbo's and engine building at the moment. Sent out my SDS ECU for a software upgrade, nice to see I'll have the ability to log AFR's afterwards. Adding a wideband to the list of things to add this winter. Ordered a whole mess of electrical stuff from Del City too, after seeing 240hoke's recent wiring work I felt extra shamed about the condition of mine. (especially since I have spent so much time fixing other peoples wiring on their cars) Time to address that to my satisfaction. Getting close to turbo and piston orders...

As subjective as these kind of statements can be (and I know all the disclaimers that go along with them) they are quite helpful to me. If this car wasn't going to be used for autocross the T3/T04E 50 trim 0.63A/R was high on my list as good bang for the buck. KTM, what RPM do you start seeing boost by?

Depends on the location so much, it's hard to say for me. But if that car was an average Z here I'd say $7000-$8000. Since it's a California car it's would probably be worth another $2000 up here due to the lack of rust.

The thing is, even with more (peak) power I don't think it's likely to make me faster around the autocross track. I could use a little more at this point, but to be honest not a whole heck of a lot more than the 232rwhp I am making in the previous setup. Widening the power band would be more useful to me, as well as adding some area under the curve. Famous last words, yes. But for the purpose I want this car to serve at this time it makes sense to me. I can always buy a bigger turbo later.

Thanks Austin! Nice to feel the excitement again when I look at the Z. I spent far too much time working on other peoples cars, sortof lost the appeal for me for a while. I see you are still building, even after completing one of the nicer Z's out there! Point noted on the CR. I've had some detonation issues in the past and might be overly passive with my selection of CR.

Thanks for sharing your thoughts. I'm not overly concerned about "wanting more later" as this is later. I'm fully prepared to buy another new turbo and make the mods necessary if that arises. However, I've been driving this car for 10? years now, and for my uses (street/auto-X) there is a limit to practical power levels and I am more concerned with power delivery than the peak number. The engine config I am looking at is only 63cc less than the standard L series turbo, and has a full 9 points more compression. (7.4:1 vs. 8.3:1) I expect it will spool as well as a stock turbo L28 (or maybe better) in the end.

Bringing one up from the dead here, but with a new twist. I am looking at doing something similar with a turbo engine. In the end, I will give up 63cc's worth of displacement from my current configuration, however, rod/stroke ratio will go from 1.65 to 1.80. At the same time, compression ratio will go from 8.3:1 to 8.5:1. I'm of mixed thoughts on this setup. The idea was that I could broaden my power band, by adding a bit more usable top end without losing much down low. I like the idea of slower piston speeds, less piston side loading and increased detonation resistance that goes along with the longer rod option as well. Option A: 2690cc 8.5:1 CR 1.80 rod/stroke 88mm bore x 73.7mm stroke Option B: (current) 2753cc 8.3:1 CR 1.65:1 Rod/stroke 86mm bore x 79mm stroke And for giggles, I'll throw out another option: Option 3: 2883cc 8.6:1 CR 1.65 Rod/stroke 88mm bore x 79mm stroke Application is autocross/street (turbocharged) and the goal is a modest 300rwhp with seamless power delivery.

I'd also be interested in hearing characteristics of other turbos in that size range... I keep hearing the GT35 as an option but it feels a little big for my rather modest power goals.
