I was just wondering if there is a place i can go or a site to visit that can give me an idea of how to beef up my ride. I'm interested in getting more KW out of her but keeping her a NA. Is there a list if things i should do/can do to make her a little powerhouse. Im kinda new to this so any advice is apriciated. Im willing to learn lots as well as thats half the fun of owning the car. and how do i get rid of the limiter as well cheers
No idea of a place to go in Qld... but there are various things that can be done on an NA for more power. If you browse the technical forums or even the UAS website. (try the link below) and under 300zx performance or something, you can see the various stages you can do and put in your car. (all that really matters is $$) UAS Good luck in your upgrades and Happy Zedding. Cheers.
Hi Terry .... a few ideas here >>>> Go to TTZED and check out the stages. First up get a pod filter if u don't already have one. RichO has just ordered from TTZED & we'll prolly fit it on the Tech Day. Next exhaust & headers! Then ECU. Rev limiter gets modded at this stage & speed limiter removed. How's your brake pedal? Firm? Or does yr firewall & booster move quite a bit? You may need a Chili brace. See ya on the 3rd eh?
Cool thanks for that will have a look through now. Just out of interest has anyone ever supercharged A 300?? just for somthing different. another thought. What about the Cam and changing the pistions to forged?? cheers
Terry, adding to K-Zed's suggestions... Cams and pistons are big costs. If you are committed to keeping your NA, then might suggest you do the easy/cheaper mods first and guage your satisfaction at each power increase. You may find that with pod filter/exhaust/headers and ECU upgrade you are reaching fairly close to stock twin turbo range which is around 300hp. If you still aren't satisfied, you might try contacting Trayns who has one of the strongest NA's in Qld as to mods he did. PS: Coming to tech day?
I will try and make it along to the tec day. Does it matter that i dont need to work on the car at all? I just went to the site and priced all the parts listed. Im looking at $8k + the cost of and the ignition upgrade. to get a gain of 100kw. time to start saving i feel. the list is as follows. Stillen hi -flow intake $355 Stillen Exhaust $1965.87 (already have an aftermarket exaust though) Stillen Underdrive pully's $1112.00 Stillen Headers $680 Stillen Aluminum Flywheel $950 Street/race Camshaft 1076.95 ECU Computer $795 Extrude howed oplenums $780 these should take it to aprox 322Kw is this good for a NA? optional extras stage 4 break kit $3709 Forged pistions &1710 May need a new clutch though. It is hard to put her in 1st gear mabee it's like this with all Z's.
Re: Qik & ezy and cheap...fit nitro!! LOL lol highly illegal in QLD even hoses for Nitro is big bad pull off road by the police. Funny how i can go to the dentist and have Nos for pain killing and no worries there. Mabee i should breath it in and blow it into engin when i get out
Save money easy by >>> >>> firstly get a UNIFILTER from TTZED for around $170. What size is yr exhaust? You may only need headers & any competent exhaust shop can prolly quote you some pretty competitive pricing. Do UD pulley later when 100k service is needed or during engine pull. Not worth the expense on it's own. ECU upgrade ... can do locally for $600 or order Hi-Tech. That's around $1500 spent wisely - not a bad start. Come to Tech Day & talk, listen, watch ... pick up ideas or just be sociable.
2nd'd on K-Zed's suggestions ... spend wisely to allow for unexpected repairs which always arise from pushing your 11 yo engine:zlove:
Read (long) Before you do anything check: Compression ratios. - Check how healthy your engine is first. If some or all are low, then no point spending tons of cash on it unless you get it rebuilt. You can do these mods way cheaper Hi-flow intake $170 Underdrive pulley $350ish (only need the crank one. The accessory ones are just for looks and do nothing for power). Full Exhaust - you said it has an aftermarket exhaust though but check if its from the engine, back. Stillen Headers $680 (or HPC coated at $990) Superlight Flywheel $600,+may need a new clutch ~$600. 1st gear synchro wont make it easy to get into at speeds in motion espcially 20km/h+ anyway. That is the same for all zeds. Street/race Camshaft $1076.95 - Another mod thats meant to give lots of power for the NA. ECU Computer $795 - Whichever ECU you get, you will (should) get it tuned on a dyno to make sure air/fuel ratios are spot on. (and at least you know exactly how much power you made). Extrude howed plenums $780. Could also get extrude honed throttle bodies. (~$500). For an NA this will give better gains especially if your old ones are sticky and dont open 100% <-- Extrution honing bits on an NA wont give you a massive increase. (at least not one you will feel). Brake upgrade would be a top idea but you dont need to spend $4000+ on it. Save some money or spend the rest making it handle better, or make it last longer. Might want to upgrade your radiator and all cooling pipes and hoses etc if you are doing all this anyway. A little money now could save you a lot later. All of that might cost just over $1000 (plus labour), maybe less. But be a shame if you lost it all because of a cracked radiator hose/tank etc. I would suggest you do most of these all at once for two reasons. 1) Cost. A lot of these are very labour extensive to do on its own. If you got the cams, headers, flywheel, clutch and exhaust if needed, for example all at once, you will save mega bucks. 2) Seat of the pants feel. The more done at once, the bigger your smile from when you really feel it. NA mods dont give massive results on their own. On a turbo zed, each mod can have 3-4+ times more effect on power than an NA (eg air pod, mufflers etc). A mod such as ECU can be WAY more gain for TT (after the fact you can raise boost safely etc), as some ECUs or chips for the NA will only give a gain of 1kW or can even make less power. Labour is going to set you back thousands. But if you did do all of the above, you would have one of the most powerful NA Zed in this forum! Remember You may make close to the power of a TT after all that but you will still have (and always have) LESS torque. So dont expect it to pull as quick Speak to Tranys though. He has gotten some very impressive times on his moderatly modded NA. Supercharging a zed has been done but note: If your using the NA engine your max SAFE boost might only be 4psi therefore power gain wont be much at all unless you use a TT engine so can have more boost. You will probably lose your Aircon and maybe other bits If you are going to do it, do it only to a workshop thats eager to take it on or has done it before. Otherwise it will sit in their workshop for years (has happened to cars less complicated than the zed from what i've heard of peoples projects). Good luck on whatever you do :zlove: :zlove:
Supercharging..... A few forum members have already investigated this and found its not worth it. It still wont be as quick as a TT and there are some compromises. You'll lose your airconditioning cos the supercharger will most likely go where the A/C compressor is. The engine bay is tight so there's no where to put it. As for internals, well you can go down that route but it will cost you heaps of cash and for what gain?? Its not like you can up the boost or anything like that. The NA just doesnt have the same gains that a TT has, unless you NOS it. I have had some of my internals "worked", along with exhaust mods, ECU mods, Air filter mods, headers etc etc and I'll be happy if I reach the 150rwkw mark when my tuning gets sorted out. If you want lots and lots of power, you may have to sell it and get a TT, or drop in a TT motor like Shifter has done. But even that will cost you close to $10K. The NA is fast, just not TT fast.. Cheers
Hi Rob Was talking with Simon about headers and he was not pushing them, he said go the pulley and pod and chip, but reckons the headers wont do much for the price, have you experienced any different, was going to purchase but now confused. Cheers Scott
Hi Tezza Once again in talking with Simon at TTZ he also directed me in the thinking of other brands that will do just as good a job and half the price, have a chat with him, great guy and he certainly knows his stuff, the same as most of the guru's on this site, we have some of the best here in QLD. Cheers Zedmeister
Can't understand that logic >>> >>> as a free-flow exhaust is one of the biggest HP mods you can do. UD pulley gives minor HP gain + quicker launch, ECU very little HP gain but needs remapping after intake/exhaust mods to remove speed/rev limits & improve AFR's. Ask Trayns, Aza, Jedi & other NA'ers.... they're the experts.
Use this HP chart as a guide http://ttzed.com/products/products_index.cfm?grouping=1. Headers appear to be one of the best bang for buck mods...
I'm working on justifying spending 7grand + on the car if im not racing it. It would be nice to do though but as you say. Thanks for the advice about getting parts done all at once kind of thing. I didnt even think about the fact of labour cost heaps for each indivually but together much cheeper. Is there a way i can find what has been done to the car already. I havent really done anything except add the sterio to it since i got it. How would i find out what mods are all ready done. Just take it to a mechanic and ask him to look?
