So far the mods that seem useful to me are the following:

Fairly Mild:
S-Tune Suspension
Borla Dual Cat Back Exhaust
Front Wheel Big Brake Kit (if you don't have the track model)
Racing tires and wheels

I little more aggresive:
Doug's Headers
Lightweight Flywheel
Lightweight Pulley Set

Going nuts:
New cams
ECU
Nitrous
FI

The mods that are more for looks and fun are:
Grounding Kit
Intake


I personally will probably never get more than my "wuss" list. But if I ever get rich then I might venture into some of the others. I may make my own grounding kit, but mostly just to see if it actually works, since many people swear they make a difference.

-D'oh!

 

These kits are dyno proven at least from Hyper Ground. Biggest gains are coming to older cars, like 3rd Gen RX-7 which saw gains of around 13hp. Newer cars are well grounded until you add a device which puts a large strain on the alternator.

 

what's the thoughts on a lightened flywheel and turbo? i know on a honda, it wasn't really recommended. also, on the grounding kit, wouldn't a custom kit do the same thing a retail kit would? i mean, it's just a bunch of wires and contacts.

 

I can't see the EVO getting much more horsepower unless someone throws in a bigger turbo. My close friend owns an EVO, and it runs 19psi boost stock. I can't imagine him wanting or needing to up the boost anymore than that. The car already comes with a good exhaust (maybe), huge front mount with water sprayer. For an EVO guy to go faster, it takes a turbo upgrade. Their turbos are already good TOO though, they're about the size of a Greddy TD05 which is a 16g. Those run up to 275-350 hp I'm guessing. I own a 91' MR2 turbo and 70' 240Z, and contemplating the 350Z for next year.

 

Evo's come with a "Big 16G" titanium blade, which is rated to support about 380 hp. It's actually fairly effecient for a while after 19 psi. There are some guys running up to 30 psi, at some point in the rpm range, on pump gas, with new pistons, crankshaft, and rods. Getting about 340 hp to the wheels .

 

well, now i know what my next mod is. i gotta ****in get my back bumper repainted cause some cuntrag scraped it with his car last night. i was in damon's, came outside, and i got white paint and scratches across the center of my back end. i don't even have the car a ****in week. makes u wonder if it's worth it tryin to have a nice car with ***s like this drivin around.

 

Ok, I'm wrong about the EVO stuff. Now tell me YOUR opinion on not going 8.5:1. I think its best to stay at a higher compression and use safety equipment such as intercooler, water injection, good timing and fuel to fight detonation. 8.5:1, brings the power down, and you try to make up for that with boost. I don't think that is a good idea.

 

I could go either way really. One side of me wants very low CR and lots of boost for a screaming fast high-end. The other side wants higher CR so I don't lose that low-end grunt (before turbo spools) that I've come to enjoy. Realistically though, with the information (limited as it is) that I have now, I would say a 8.5 CR would be a waste. The reason is because with that low of a CR you can run a lot of boost. It seems that the internals, namely the rods can't handle the extra hp that high boost would give and we would give up the low end without being able to totally use the high-end potential of the turbo. So since the internals can't handle it, I think going a bit higher with the CR and lower the boost to a point where the internals will be OK is a good idea. With the 8.5 CR we would run into problems with the internals long before problems of detonation with the associated boost. A bit higher CR and won't lose the low end as much.

Now if the plan is to change internals then I'd get the 8.5 CR. You can run plenty of boost and have great power. I'd be willing to give up some low-end, I guess . But turbos spool quickly these days...they are very effecient. So I guess it just depends on what you want to do and which side you want to sacrifice.

 

If you want to keep your warranty, I would wait for a true dual Ti exhaust setup to come out. If one exists currently, I don't know about it, but I'm sure there are a couple in the works. This should be good for 10-20 hp at least, not to mention the weight savings. I would also probably invest in some new wheels, again for the weight savings. A grounding kit is a really good idea. I would probably go with some form of CAI... even though it hasn't proven itself (at least to me) to give more hp right now, it probably will when the ECU gets cracked.

Usually when you just do those mods, your dealer won't give you much crap about your warranty, headers could go either way, some dealers care, others don't. If yours doesn't care, I'd go with some good longtube headers, crawford has done a good job, and a lot of people on here swear by their products.

Well I'm by no means an expert, but I would start with trying to shave off weight and basic bolt ons basically. If you did all that it would be probably 3000 or so roughly, but you'd be running mid 13's probably. Good luck with everything.

 

i think i'm gonna wait for some of the fi kits to come out and have people put some miles on em to make a decision. i am shootin for mid-12's, so fi or nitrous is a must. i had a juiced civic and got sick of it. i must b patient .
