What Would You Upgrade Next?
Hello Forum -
Criteria: I'm looking for the best bang for the buck (performance to dollar) upgrade reasonably within the $1500 (+/-) price range. I'm hoping to get some advice from those of you who have heavily modded your car... maybe a "if I did it all again I would have done ...x..y..z. first" but all advice is welcome!
I should preface by saying that my long term goal will be to stage 3 SC my car, but its a long... long term goal as I know I'll have to build my transmission first ($$$$$). Anyways, here is a list of my current mods for reference:

- ARH Long tube (with x pipe)

- Lightweight rotors all around for added VTEC in gears 1-2 and a bit in 3.
- Then you'll force yourself to do LSD after that when you struggle to put anything down in 1st gear.
- E85 to sail past 500rw and really get the hammer down.
- Lightweight crank pulley (assuming you meant light crank pulley and not flywheel, although even if you did mean flywheel, a lightweight flywheel is a fairly useless mod by and large in any car) is probably not worth the small risk involved in running one (has potential to cause long term engine damage). Perhaps just get the rev limit increased to 7500rpm instead. Many have done it and you'll be fine if you're sensible with it.
Used will be cheaper of course. I think DocOC is selling an E85 kit and I'll be selling my lightweight rotors too in the coming weeks. LSD...try and get one from a salvage yard. Should be able to halve the entire cost above and maximise that bang for buck.

Wouldn't bother with the lightweight pulley. Sometimes does more harm than good.
I'd go LSD first, if you want to go looking through scrap yards as mentioned you could check car-part.com
Then lightweight rotors and then e85
But that's just me lol

What are you looking to do? Drag strip? Road Course? Canyon carver? LSD will help all of those. But then if you are going to supercharge the car and do drag strip work, definitely wheels and tires.

Again, it depends on what you want to do with the car. for a drag strip, a helical diff like a wavetrac or quaife will do just fine. for a road course, a clutch type (stock LSD) is usually considered better. clutch type diffs work much better when one wheel has zero or near-zero traction like if you lift a wheel going over curbing or if one wheel is on ice (not a factor since you said it's not a daily). The ice part is less of a factor also due to the car braking a spinning wheel for you to keep a helical diff working. I have a wavetrac and I love it. the big benefit IMO would be just being able to swap a whole pumpkin in without someone having to tear apart your stock diff.

Chris nicely explained the difference above between the different types of diffs. What are your thoughts/how you'll use the car? I think if you're ultimately going to do all of these things, then do it in whichever order you're comfortable with. I know an LSD isn't the most 'glamorous' of mods because your car won't really be any faster, but it will make it more usable. You'll probably want it/make yourself buy one if you add a little more power via either E85 or lighter driveline components (brakes, wheels, tyres).

but I would say I care more about handling (canyon, road course, etc.) than I do about the drag strip. Not to say that it won't be fun to do some weekend pulls in Mexico... but for the long term I'm thinking course.
