Z31 turbos are the best cars. They cost less to get them to go fast than any other Z. Definitely best bang for the buck. I sold my 95 TT to keep & build my Z31 turbo.

I have o disagree, the S30 is the cheapest car to make fast, it's also easier to add an intercooler to the early chassis, and that fact that it weighs about 1000 lbs less is a big help as well, building another car that should run 11's for under 2k

but it's very difficult to find one for cheap that isn't rusted to ####.

And since they didn't come with turbos, you also need to find a turbo motor and yadda yadda yadda.

Everything else makes sense though.

You're Both wrong cheapest to make the fastest and easiest to get the parts for is definatly the s130.

That is IMO.

heh, the S130 is a bit heavy but if you can find one that isn't wrecked or rusted, personally I havn't found a donor with a shell worth saving yet, and if you know what your doing with the L28ET all you need is the manifold awhich you can buy tubular aftermarket but the stock piece can be had for about $35, just add MSnS I/C and T3O4E

and yeah it's ahrd to find the S30's in good shape thats why mine is rusty bit fast, of course in my area most Z31's are rusted up as well and cost more

Very true but in my area s130's are very prevalent in the junk yards. Hardly any s30's. So I guess it's just depends on want you have available in your area. Now about 5 years ago here S30s were everywhere. And I don't agree with heavyness. It was 50 lbs less than the 280z according to this.

my 240Z wieghs 2105and before I messed with it it was still 2250 (early cars weighed less than the later 240's the listed weight is correct for a 73 model)also keep in mind there was a great deal of variance in the S130's. the early slicktops with manual steering to the later turbo's with leather, all power options, heated side mirrors and auto rear defog etc

and I think the listed weight on the Z32 is a buit low

but in the end, one turbo si a lot cheaper than 2 ! and one cam is cheaper than 2 or even 4!

keep watching GRM for Z's in the $2006 Challange (Including mine) and be watching pinks for a very fast S30 beign built by a group of HybridZ guys (I think they race this weekend)

Sorry. I guess I shoulda been a bit more clear about my statement that the Z31 turbo is the cheapest to make fast. I meant WITHOUT engine swapping. It has a great platform to start with. TTs are by far the most expensive, 240sx are hard to find in good shape or inexpensive, earlier Zs are hard to find in good shape.

The only reason I have about $12,000 into my Z31 (spent over the past 6 years of ownership) is because it was my first Z31 & I bought things (like springs/struts) more than once until I found the ones I liked best. Now I could build the same car for about $8,000 with all the upgrades mine has. My car is great at the track/autocross & is respectable (for now-it should run low 12s) at the drag strip.

Try starting with $1000 or less to buy the car & build from there. I still think the Z31 would be the least expensive. Didn't Sport Z Magazine list the Z31 as the best bang for the buck outta all the Z cars in one of their past issues???

Just my two cents.

My lil brother would agree with you. I sold him my 95 TT - his dream car. 72,000 miles. Original paint which is perfect & interior is also perfect. There are very few TTs in this original & near perfect condition around. GORGEOUS car. Minor mods like ECU/boost jets/downpipes/clutch/springs. $16,000 is what I sold it to him for. Runs low 14s. (don't care what people say-they didn't run 13s stock)

My car. $12,000 so far. Not nearly as clean a car-I'll admit that. But MUCH faster & would kill it on the track. More unique/rare to find for MUCH less money.

He loves the TT the way it is & I would rather have something faster & less expensive to mod & repair. Worked out great for us both.

I would & will put my Z31 up against any TT at the track or autocross (which is what I built it for) and it is respectable at the drag strip. Unlike most TTs, mine is not built specifically to go straight. It is a sports car after all. Mine will cost less if/when things break & cost MUCH less to build.

Sadly I never find any TTs at the track or autocross. Only at the drag strip. Here in Vegas there will be a large CA/NV meeting of Z cars in mid June. Mostly Z32s form what I've read. The only racing event planned for sure is drag racing Friday night. Go figure. A sports car going straight. No one posted any interest in going to a track event or autocross.

So my personal feelings remain. For the $$$$$ Z31s rule.

I met a guy who bought a Z31 turbo at auction for $200. Put a 50 shot on it & manual boost controller & ran low 12s. Said he had about $500 total into it. Next he was going to put a homemade intercooler & 100 shot into it next. But it was a rat. Body was hit & the interior was so torn up it was nasty looking.

Depends on what you are looking to do. If all someone wants to do is go fast in a straight line then any Z can do that cheaply. But doing well on a track or at an autocross & then looking good on the street are totally different.

It's all relative.

See most of the TT's around here aren't built for straight lines, so its the opposite of out by you. I hate drag racing anyway, its so freaking boring, auto-x and road course is where its at.

And as for drag times, I ran a 12.86 in my 90 TT with intake, test pipes, catback, and ecu back in spring of 2002. I've seen stock ones get into the high 13's around here.

I wish that were the case here. We have lots of Lotus Elise, Vettes, EVO, & Subaru at the track & autocross. I am usually the only Z of any type racing. As for drag racing, I like it enough to go out a couple times a year. But that's all I can stand. To abusive on the driveline & too boring waiting in line. I agree that the track & autocross is where it's at. Gotta have the twisties.

in the GRM challange my car will have to autocross as well as drag race, the Z31 is a competent cuildable car as well but it has more weight to overcome and you can't see the turbo from the topside and the exhaust crossover is a nightmare, I've owned ll by the Z33 and the L6 is much easier to work on, and cheaper, the problem is the ancient 30year old design makes for obsticales that must be overcome, cst pistons, no quench area, intake and exhaust mounted to the same side of the head (althout I have gotten pretty ued to working on the stacked intake/exhaust)

Agreed.

just too bad most of the Z32 owners are like MKiv Supra owners. Fast cars, slow drivers...

and the cheapest car to build fast is a Miata. '91 Miata for like $1500. strip it. slap a turbo on it. add a roll bar. bam. 300hp, 1800lbs and a blast to drive. In terms of Zs... i'd go for the 240z. Something about them gives me goose bumps!

but, i can't talk... i own a CRX, although, I haven't seen any Z post a faster lap time than me at the same track day. :nudge nudge: MARK!

ps. 100 miles down. 900 more to go before my car can beat the crap out of your weak 13.3... bring it, BALLS Challenge!

pss. your car is still damn nice... even if it isn't a Supra or an Elise.

the miata's are fun but the turbo doesn't help their complete lack of low end power but they are a hoot to drive and have aobut 30 years less rust to deal with and provide a simple light platform to build from (too bad they are convertible only) but you get their lackluster soapbar styling, I prefer the sexy lines of the Z in all it's generations, it's also hard to find miata's cheap as the spec racers, autocrossers, midlife crisis, and doctors wife all snatch them up

Problem with the Miata, it's for midgets like YOU. I can only see the top frame of the windshield when I sit in it.

Faster track time than your CRX? Coming this weekend. Be prepared to being seeing a LOT of my tail lights like you do on the street.

Weak 13.3? That was before the gutted intake & on 14lbs of boost. I now have 17lbs & the intake. Dyno tuning tomorrow night as well. Didn't we line up the other night? Didn't you get to see the back of my car all night?? I'm only gonna get faster.

Well, unfortunately The BALLS Challenge set something straight...

"My 340whp Z lost to aHonda CRX HFatTHE BALLS CHALLENGE"

That's what the window sticker is gonna say
