so just randomly asking here are we saying that 230-250rwkw is a good mark.. but perhaps have the engine built to handle say 320 :S i know a few Z that can run about 300 on 20PSI.. .. but i think thats really giving hte engine a cooking.
When rebuilding an engine your almost always limited by money, rather than hp. You usually build the best you can afford.
230 - 250 is pretty easy on a stock vgtt - minor bolt ons and tune will have you there easy as:zlove:
soo.. lets just say this hypothetically.. reworked engine including bored cylinders with forged pistons, high flowed turbos, haltech engine management computer dynotuned,high pressure fuel pump, 2.5inch twin exhaust sysem,fat front mount intercooler,blow off valves, injectors and pod filter ? running 12 PSI what should that be putting out ?
Yup, depending on manual or auto turbos about that. Upgrade those and you'll be able to explore your setup potential some more! Good choice with haltech btw
sorry forget to mention the obvious of large front mount, radiator, exhaust (2.5 inch dual)... cause... i guess then i can look at gearbox and drive train/suspension to assist getting that power down and the actual ability to turn a corner with that power lol.. give me 2 years guys . haha
Gearbox should be fine, forgot to say you'll want to be running more boost than 12psi, maybe 16-18psi for that power level. Lloyd has been running hi-flowed turbos at high boost for years without problem! Upgrade your clutch, and maybe get an adjustable fuel pressure regulator also. Good thread if you search "looking to make 250-300rwkw, what mods do I need" or thereabouts! :zlove:
here is a question... are high flowed, reworked stock turbo's (T25's).. better hten just upgrading to T28's :S?..
Stock turbos are actually a hybrid garrett design, maybe somone can expand further? But a T28, say as on an S15 (not bolt on for 300ZX) will flow more than a high-flowed stock 300ZX turbo because the housing is bigger. My turbos are hi-flowed, fitted with T28 compressor wheels which flows more than stock but it is still being restricted by the housing - on the exhaust side especially. If I had my time again I would probably give the hypergear turbos a try!
putting out about 20k + GL. For all those who have not done a build like this and wasted your dollars, save your 'AS IF'S' and leave it to the people who have done it.
youre the only idiot here who has spent 20k+ for a pissy 14.8 second car ,the zshop saw you coming rofl
You lot want to get your hand off it. Anyone who goes to the drags with their ( dont it look cool lowered ) bullshit hard suspension and expects to hook up during a drag are dumber than I think you are. Drag setup is an art. There isnt one setup that is optimized for the street and the drags. So you have the worst of both worlds. Have a close look at your car Alex. Its too low for the suspension to be good for the street and its too hard for the drags. The oh so great Tiens you all bought, havent got the valving to to be adjustable to any great extent. HR's and HA's have shocking hard Spring rates. They would NEVER hook up properly at the drags. Grow up and start seriously looking at what makes your cars FAST. Its the suspension NOOB's. 250 RWKW with a compliant suspension will always be greater than 300 RWKW with a stupidly low, hard riding suspension.
or the track ! If I leave my car setup in 'drags mode', it costs me 4 secs at the hillclimb track..... 4 secs is HUGE when one looks at the distance of 1km !!! Same applies to running it at the drags when its setup for the track, its 1.5secs down on "normal times" with my 60ft times being shockers !!! Teky is right in saying .... 250 RWKW with a compliant suspension will always be greater than 300 RWKW with a stupidly low, hard riding suspension Its basicaly the same as I said earlier.... having 800HP is all well and fine, but useless if you can only put 400 of it to the ground effectivily The exact same argument also applies to the brakes..... By all means upgrade your engine and its performance, but you'll gain even more with a suspension upgrade and a brake upgrade that enhances the engine power increase All up and truthfully.... its a pure balancing act of all 3 sections to get the best from your car whether its street, strip, or track. Kingy
People are forgetting that the drag stip is only 400m. And our cars are kind of crap at drag racing anyway. Well maby not the car, but more of the street setup people run. Drags are just fun for most people its hardly a performance reference.
dear tek for a start tek ,, my suspension is not too hard for the street , track , and whatever/wherever i put it on ...and i have had a close look at my car , and i will be going lower soon .... how can you judge my suspension when you know nothing about it . all you know is that i have twin spring ha's with dampening control ...... you have never sat in my car to know how it feel ( just a ten min drive that's all ) ( you're just judging it ) and what your saying is just an assumption ) tein are not all HARD suspension ,, they do make soft springs as well. one man going up against tein , ( nice work ) when I built my car starting from 13 years ago, i never built it to serve any particular purpose .. it is not a drag car . it is not a circuit car . it is not a drift car . it is a good all round car . i can take it to the drags when i want, track when i want and so on .... when i go to the drag it's soft all the way .. when its on the track i adjust it to my liking ... and so on ... when im at the drags, with the slicks on, my car hooks up 100% i have vids here to show that .. ( with over 300rwkw do you think any street tyre will hold any zed ?) i think your talking about 90 / 10 set up from back in the day. and yes i would agree .. and at the end of the day its my car, and i built it for me, and i dont need impress anyone. p.s as you cant stand lowered cars i cant stand cars that look like 4x4's , so in my opinion the lower the better ( in my opinion ) so please tell me ,, what would be the point in me spending 10,000 $$$ on suspension,,, especially when i love the way it is , and p.s.s my car will NEVER go higher.. i dont care how much time i lose in any event
