300rwhp goal opinions
#42
After reading this. I'm guessing this is your first car? Maybe your first car you could mod. You really need to do alot of research before you go F/I or any type of mod for that matter. You trying to beat him in a straight line or on a track? If its track, spend money on sways, coils, and tires. If its in a straight line you'll never beat a 911 Turbo. Unless you get a built engine and twins and even then you are probably going to struggle from a stop. A Z is a torquey car from factory.
Personally if I had 5K extra, I would spend money on suspension and then spend money on HP mods. You'll have a WAY easier time beating him on a track versus a drag strip.

I know someone whose putting down 306whp on a dynapack.. mods included modded lower plenum, plenum spacer, gasket matched lower collector, shorty headers, HFC's, FI exhaust, under driven pullies, rev-up z intake box and z-tube, 3.7 rear end and a light weight drive shaft... all tuned by Church Automotive.. driven the car myself and was very impressed by the performance and response.. next stages for him are new heads and long tubes which should provide significant gains..

IMO 300whp on a dynojet SAE is doable on a stock long block DE. You'll need a strong motor, creative plenum work, optimized breather mods (filter, velocity stack, maf housing, intake tube, headers, tp's, most likely a short/dump exhaust). On top of that, it won't be on pump gas. I have a feeling an E85 car tuned to the point of explosion would be enough. I'll be putting together something over the course of this season that is legal for my racing class. 300whp is the goal on a stock 03-04 long block. My car made 280whp on a dynojet on a stock plenum (with spacer) and 93oct gas several years ago. We'll see how it goes.

300whp is just a number. You might go to one dyno and read 270 then read 310 on another without any changes. It's been said many times before, but what you need to be concerned about ( more so than a final number ), is the gains you're making with your modifications. Like I said in my earlier post, it cost me about $5k on my HR to get from 254whp to 301whp on a dnyojet. 46whp for $5k...rediculous.

hks ssqv $75
tial 38mm wg $250
garret gt3071r $1300
sell godspeed turbo/bov/wg $-300?
so add say $1325 on top of that quoted
EDIT:forgot fuel pump for like $250
then id feel a LOT more safe than that gsp grenade spinning under my hood, and id probably feel pretty safe running that system at 6psi, add in datschworks 600cc injectors and id feel even better and possibly push to 8-8.5psi spring, then youd be up around 400whp and in the neighborhood of 5k but then why not just go out and get a boosted performance kit with probably much better fit/finish and much easier install, for only a few hundred more? then you could support my canadian economy

Do any of you have any experiences with the Z1 Plenum Spacer? I bought one during the summer and I haven't installed it yet but I just wanted to know if there's anything I should look out for like my check engine light going off or something.

If your getting a ssqv for $75 its a fake and likely no better then the junk the turbo kit would come from, you will also be lucky to get $100 for the junk wastegate and bov so figure actually close to $300 more then even what your thinking.
Also welding is gona be more then $400 if you need coldside welded, tig isn't cheap, hotside could be mig welded but still I would say closer to $600 to be safe and you still have inferior alloy thin walled tubing that is just going to have issues.
The mere fact people even suggest modding this kit is a embaressment turbonetics is better and even that kit is absolute junk.

if you wanted to be more safe, swap out the godspeed turbo, bov and wg for more reliable stuff

Feel free no one here will really care until the turbo grenades then we will chuckle a little and move on. 9/10 the bearings are shot on those turbos before 10k miles and the eat the wheels. The welds crack, the kits don't line up..........everyone hates on them because of how many times people have had problems with them. At the end of the day you spend as much money as a actual good kit and the result is still sub par that's why everyone hates on turbonetics too, no matter how much you polish crap its still crap.
You can get quality cheap stuff, my meagan headers hold up great, but they don't have any weight on them. You have to be smart about it and a $200 china turbo isn't the way when you can get a holset for about the same price it just isn't going to be optimized like a name brand turbo. Even still it will perform better then the china crap and the mig welded standard tubing(I can promise you its not stainless the honda guys seem to think they are badass with em till I destroy them and they blow engines)

Lol, just for everyone on this forum hating on godspeed turbo. I'm going to buy a kit and install over the winter.(I have 4 other cars and drive the z 2500 miles a year) People always dawg it, but I've used cheaper than cheap turbos/piping/ic/manifolds on a custom turbo kia sephia and a kia spectra with no problems.
#56
I'm not putting a cheap turbo in my car so stop recommending them to me. I raised my budget limit to 8k because I rather not get over 400 horsepower for a day or two then the cheap turbo fails on me or worse. But back to my next baby step with the Z1 plenum spacer I didn't install yet. Any thoughts, tips, or anything i should be aware of? I read somewhere that when you install a plenum spacer the air to fuel ratio starts running lean or something.
#58
I have a bond with my 03 and I don't plan on selling it ever. When I do get another Z it will be a 370Z, Datsun 280Z, or a late 90s 300ZX twin turbo.

Well I am keeping my 350Z. I always loved all the Z's and want to collect 1 from every generation one day if I can. I already have a 350Z so I'd rather not get another one but build up this one. But that's all further down the road. The here and now is I want my 350 to beat my dad's 911 turbo in a drag race and on a circuit. But me collecting all the Z's doesn't have anything to do with that.
