drive an n/a and am looking to get the most possible power out of my car currently has twin 2.5" catback exhaust mandrel bent with hi flow cats and a pod setup....thats the only mods.......ive got 2k to spend on performance atm any tips?
$2000 of stickers is your best bet lol but on a serious note,suspension,brakes,udp,ecu chipped building an n/a for straightline speed is pointless,thats what t/t's are for,build it for the twisties and not much will keep up with you :zlove:
I agree with the above, some coilovers and swaybars are a good start. For power get an UDP and some copper sparkplugs, for braking get some good pads for the front and there might be some money left for an ECU remap
udp is just a racing drive belt right? ive allready got platinum plugs and looking at getting brembos front strut bar rear and under rear bar does anyone know roughly what hp gain id get from a chipped ecu and full dyno tune?
Purely a performance mod.. Haven't got one, but should be around 10-15hp for NAs. Also may make the engine more responsive.. I'll let someone who has one on their NA answer this one. -Kirill
kk n/a are so limited in terms of performance mods well in comparison to turbos that is how much would a set of forgies set me back? anyone
An engine rebuild ? dont start with less then $10,000 if you are going to pay someone else to to do the job. But if you only have $2000 dollars to spend, I would look at the things that need doing on the car or keep the money for repair bills that are likely to appear, better to have a slower car running then a faster one sitting in the yard. If the car is essentially in good condition as in suspension/brakes/cooling system/100,000 K service etc etc ... as well recommended above. Here's a links to an NA power mod stage list by Stillen. You can click on the stages to go to the products. http://www.ttzed.com/products/products_index.cfm?CFID=21292107&CFTOKEN=4637937&grouping=1 You would probably do headers and pulleys for $2000, but you would probably want to put it on a dyno to see if AFR are good, with an NA you should be OK. There are some link in this thread also, but you already have some of the gear. Don't forget to allow for fitting and US freight. http://www.aus300zx.com/forum/showthread.php?t=287899&highlight=$3000
Try using search function before posting. All these questions have been asked and answered a billion times. You won't need to go forgies on an N/A. best advice for extracting power from N/A has already been covered by zxtcy.
If I were doing an NA rebuild I would go forgies. How many rebuilds are within spec and have bores in good condition and only require rings on these aging cars ? So an oversize bore is required to clean it up, you ARE buying a set of pistons. Factory OEM NA piston sets are not listed on CZP/Z1/UAS, Courtesy Parts has them at about $580US to $600US depending on .25 or .50 oversize. http://www.courtesyparts.com/kb_search_result.php?chassis_id=6&keywords=piston+rings&cat=1 Wiseco and ACL dont have anything listed in their catalogues JE makes an 11:1 listed for the VG30DETT but I have a feeling its for the VG30DE (329g). These are about $700US a set rings included. http://www.jepistons.com/cat/je/sport/nissan/vg30de.shtml http://www.extremeturbosystems.com/....02-Oversize-Pistons-166027/product_info.html CP make some for about $750US dont know the weight. http://www.frsport.com/CP-SC7330-Forged-Aluminum-Piston-Kit-Nissan-VG30DE-87-5mm-10-5-1_p_8508.html Z1 lists Wiseco at this link for $695US for 10.5:1, probably a custom order from Wiseco that they have speced up and ready to order. I dont know the NA weight but the TT's are 335g to 343g. I reckon the NA's we be lighter as they wont require as thicker crown. http://www.z1motorsports.com/product_info.php?products_id=39 So plenty of options $100US to $150US more then stock pistons. With forgies being not a lot more $'s and probably some what lighter and tougher and the option to increase compression, I would definitely be going forgies on an NA rebuild. But you are right in a sense with $2000 he wont be going forgies. He has also listed a wanted for 19" wheels so finesse handeling mods as ZXTCY suggested are probably out, i have a feeling he's looking for straight line performance.
Yep, agree with all you have posted. I was also mainly putting in consideration his $2000 upgrade figure, which can get him "some" of the bolt on upgrades mentioned earlier, but less chance of a full rebuild. And a set of 19" chromies will chew that up pretty much straight away anyway, so maybe that is higher on his priority list than an engine rebuild....
Assuming you've done all of the maintenance work (100k service, plenum pull etc) then for 2k I'd recommend you get: -pod filter ($30 to $100 depending on what you buy) -TTZ extractors ($490) -front pipes in 2.5in ($300 approx) -high flow cats ($400-$800 depending on brand) -might have abit left over for tuning or underdrive pulley/installation that's assuming you just want a power increase. I did all my power mods last, upgraded brakes, suspension and good tyres + alot of maintenace work will give you good gains in all round driving.
and dont forget the forged pistons available for a vg30 are designed for tt's and therefore will reduce compression to that of a tt, which will suck the big one power wise on a na car lol!!
my opinion for performance gains new heavy duty (organic or 9 puck ceramic for nas) clutch and lightweight flywheel and either underdrive pulley and belts or extractors..... that should see the majority of your 2k gone alternatively if your still running stock wheels a set of lightweight 17's or 18's with reasonably wide and sticky rubber is considered an upgrade by most, and should be in the 2k area cost wise
definitely more gauges. with 3 gauges along the A pillar people will be too scared to race you, even if they're all vacuum gauges, they won't know.
