plugwires and racing 300zx
What are the benefits of upgrading plug wires? Which are a good brand? Are they easy to install? Also, has anyone ever raced a Nissan 300ZX? Are they fast? There is one I see who usually wants to race. I have stage II chips and boost enhacer but I don't know what mods he has.

I've raced a 88 or on 300ZX Non-Turbo. We did it in one lane, playing keep up. We went up to 115mph the first time and he was not losing any ground (he was behind me), but I could not tell if he was GAINING ground and niether could he. Then the second time we started at about 20mph. He was on my ass the whole time all the way to 80mph... then the cop passed in the other lane. Whoops...

Please give your opinions about the spark plug wires too. I'm gonna replace my spark pulg wires in my S2 soon too and I want to upgrade. I'd like to hear everyone's experiences with spark plug wires. Recommendations?

I own a nissan 300zx also. It can beat my porsche easily. I have a 85 Nissan 300zx non-turbo and a 87 porsche 944 NA. The nissan is completely in tune and functioning nicely. The porsche is what i am working on now and havent even given it a good tune-up since I bought it last november. But from other porsches that I have driven I think the nissan is still a faster car. though through corners it sucks real bad. But it was constantly quicker than the local 5.0 mustangs
 But I have never driven a turbo porsche ora turbo z. You can tell if the z is turbo because it will have a little hood scoop offcenter on the hood.-pete |

I owned a '90 300ZX Twin Turbo and it will smoke a stock 944 Turbo without blinking, those things are un-friggin-believable. I think that a slightly modified 944 Turbo will be faster than the Z. Driving the Z is an entirely different feel compared to a 944T, it's much more breakneck...when you hit the gas it pins your head to the seat almost instantly.
I am not sure who would win in a 'back-roads' race, the z has four wheel steering, but the 944 is a cornering monster. So, if it's a twin turbo Z you probably will run about even or slightly faster considering your mods. That's assuming the Z isn't chipped, in which case you should probably not get your hopes up. As far as plug wires, I haven't upgraded mine (S2) but I hear it's expensive and not much better. I think that something we tend to forget when doing these types of upgrades is that a Porsche is a race car from the ground up. All of these upgrades (intake, plug wires, etc..) that people talk about are usually for "sport sedans" but are unjustified on something like a 944. ------------------ Chris 90 944 S2 Cabriolet http://nbc.vet.upenn.edu/~ckrough/auto.php3 [This message has been edited by ckrough (edited 05-09-2001).] |

Jacobs Plug Wires are just about the highest-quality that money can buy, and they cost less than factory wires (what doesn't?)

I heard some things about jacobs, the improvement isn't that spectacular. I put Nology Hot Wires on mine, and their coil and spark amp and noticed a significant improvement after 4000 RPM. THe dyno showed it too. BTW: Use BERU SILVERSTONE SPARK PLUGS. Silver is much more conductive than platinum or copper

Those twin turbo 3L V6's in those things are fairly tuneable. I know the race versions run at 800bhp in the wet and 950-1000 in the dry.
One of my friends was trying to convince me that his standard (Except for some flashy 17" rims) '93 Supra n/a could out preform my other friends '83 928S 5-spd.....I don't think so, lol. He also said he could soup his car up to 500hp... what do u guys think? |

he's right about going 500 HP, but its not street legal, but if he can go 500 then a 928 can go 600 to counter that =) talk to Devek they can help on that one! My uncle bored my dad's old 85 out to 6.0 with their stroker kit, got a highlift cam, high performance crank, and compression bumped up to 11:1. With chips, the afterburner exhaust, MSDS headers, and Nology ignition the car dynoed to about 470 HP. Yes, he still had the option to supercharge or turbo charge, but lower compression pistons would have to be installed.
I have seen an article about a Black Twin Turbo 928 S4 that dynoed at 600 HP and was automatic!!!!!!!!! To think...what was that guy thinking.....must kill rice, must kill rice  ------------------ Heel'n' toe your woes away.. |

ck a TT 300ZX is in a higher class than the 951. Considering twin turbos, i believe that its best competitor would be a 968 Turbo S or a 911 C2 Turbo. I have seen a 944 Turbo blow away a fixed up 80's turbo 300ZX at Pomona. The 951 had that K-27 Turbo in and that autothority MAF GHL exhaust and headers. it's amazing how much improvement that thing does to that car. The 951 beat the Z by about 3 car lengths, yet the Z got off the line quicker.

the n/a supra he has puts out 220 hp or so. without going to forced induction he'd be hard pressed to get much more than 280. he's much better off getting a tt supra. 500 hp from those is virtually childsplay.

yeah, the TT was a different class but it's not technically twice the turbo, the turbos where very small in that car. Together the turbos were equivelent to 1.5 turbos from a single turbo z. Nissan switched to two small turbos to reduce the plumbing and decrease the turbo lag.

I have heard that you can do a TT conversion on a 944 Turbo. I'm not sure if thats right but i think you have to use an NA motor to do this conversion since the 944 Turbo motor is only specially designed to hold a single turbo. Has anybody heard of a twin turbo conversion on a 951? I am aware that RUF attempted it back in 1988 and 1989 and scrapped the project.

Holy hell, Euro! That 928 would rock!
I've seen pics of a maroon 928S (cream interior)twin turbo, intercooled. The nose was lengthened for the plumbing and intercooler. It added 20% more horse. Blackfoot, do US model Supras have diff spec ( cos of US Emissions laws?) from Euro/ JAp models cos he claims 245bhp. If you ask me, he might get a bit more from painting those nice shiny rims of his a certain colour!

yup, u.s. version 220/210 tq. and it's a scientific fact that black rims give you a 5% hp boost.
