Hey guys, I'm trying to make a list of potential modifications for my 240z that I might consider doing and would be beneficial to do while I have the car stripped to the shell instead of going back after I re-assemble it. Modifications can be personal preference, technology improvements, performance improvements, etc. I'm looking for any ideas from you guys. I'm also doing a L28 NA to turbo conversion. Are there any modifications associated with that specific conversion that would be easier to do now? For example here are some of the things I'm considering while I have the car torn apart: New dash gauges Aftermarket seats Seat heaters Blower motor upgrade Air conditioner upgrades Any modifications to accommodate a stereo system Double DIN stereo Any bracket fabrication for Megasquirt component mounting Car alarm Battery switch Keyless entry Putting wire mesh under the cowl so debris doesn't collect in cowl area
Hey guys. I'm a whore for data/info. I was wondering if those of us who have put their cars on dynos could share the results. I'm curious to see what kinds of mods give what kind of power, and what kind torque curves, how soon power comes, etc.... HOWEVER, to make certain this thread is not simple dyno sheet porn/bragging (which is not a problem here, porn and brag all you want. that's PART of the fun), I'd like to put some rule that will actually make the thread useful and easier to read.... 1. L28e blocks only. i'm curious about other engines but the second people post l24, or rb engines, the whole thread will loose focus. OVERSIZED L28 welcomed (strokers and bored engines, for e.g.). 2. Each posted sheet must be accompanied by the following info, in the following format (make certain you kindof get it right, but let's not go overboard about the form here): 1- car: year, model. 2- State of the engine: stock, stock rebuilt, slight mods, heavy mods, total-batshit-crazy-overboard-modded... 3- peak power @ RPM + boost level (PSI) if applicable 4- peak torque @ RPM + boost level (PSI) if applicable 5- short list of relevant mods if applicable, INCLUDING: fuel/ignition management, high compression pistons, turbo size/type, piston oversize and whatever else you did that could make a difference. for parts that are standards and don't really contribute like intercoolers and oil pumps and what not, no need for details. For other mods, like a crazy-fucked-up-pink-shifter-with-part-of-christian-relic-inbeded, well, if it doesn't add hp, don't list it. 6- anything else you feel might HELP OR HINDER your hp figures, like for my car, it's got a megasquirt with a tune that my 5 year old probably could improve, so yeah, that does not help. IF your engine is stock, please write the mileage here! it'd be fun to see how much mileage has eaten how many hp. 7- anything else that's interesting about your engine that can have an impact on the topic. *post dyno sheet* if you actually have a paper sheet, just take a photo with your cell phone or something, and post it. just make certain it's clear. if you don't have a sheet, just the numbers, well that's not as cool, but still interesting. post it! Comment posts ARE welcomed. I mean, i'm doing this so we can look at the dyno results and then talk about them... just make certain you don't post a sheet and a comment in the same post, i guess, to keep things clean. don't be afraid to post a sheet, then comment on whatever else in another, immediate post (like, two in a row). oh yeah! all dynos are different, there are different types, and some have to be corrected for altitude and all that. yeah, yeah, sure... that's 100% right. but I'm not doing this to compare who'd got the biggest dic... ah, HP numbers! this is only to get ballpark ideas of what mods give what kind of power. All right guys. go for it! Seb. PS: if you have a pre- mod sheet and a post- mod DYNO result sheet, you AUTOMATICALLY become king of the thread. there may be more than one king. deal with it.
