Fanman,
Any recommendations for someone wanting more power? Which mods and in what order? I've now got RB springs, sways and endlinks, and just got a typhoon II (b/c it was a great price).

Want to learn from other's mistake$$.

The best mod I ever did for the car was the RB suspension kit, so you are off to a good start.

1) I got the Rotary Extreme short ram, which was similar to the K&N unit, but later on took it out when I got the turbo kit. Wish I didn't get it, but at the time that was what was around (along with the K&N gen 1 but that was universally despised).
2) Next I got RB REV8 cat back exhaust. Loved the sound of it, but later sold it when I got the JIC Titanium. Looking back I should have just kept the RB unit. Sound is better, tips are better looking, and I shoudn't have spent $1300 on the JIC.
3) Got SR Motorsports pullies for $460. Only pully set around at the time. Dynoed it & made jacksh**. Wouldn't get pullies again, or if I did maybe the UR or Agency power. That way if they proved to do nothing, at least i would have only pissed away $250, instead of $450.
4) Got the SR Motorsports Hi-Flow cat (with additional resonator), which was a really good piece for me. Functioned perfectly fine for me when I was NA. When I put the turbo on, I had a lot of random backfire. Was told that it was because of the hi-flow cat, so I pulled it off, put the stock cat back on, and sold the unit. Should have kept it, as the problem wasn;t the hi-flow cat, it was the crappy Greddy E Manage & map. Later on I got the RP Supercat unit, which is fine now.
5) Got a Canzoomer unit, with cables & software from a poster on the board, but lost a race to a V8 Thunderbird the next night, wound up ordering the Greddy Turbo kit the next day. Looking back I should have kept the CZ & put it in my car & been done with it. See below.
5) Got the Greddy Turbo. Biggest mistake of my life. Thought it was "relatively" bolt on. Was literally one of the first 5 people on this board who got this kit put on my car. Have spent literally thousands of dollars to not only increase the hp on it, but moreso make it run right. Kit came incomplete from Greddy, and defective. I'll cover that in another thread on "Why Greddy Blows." there are going to be several much better alternatives coming out. Mine works now, but only with several thousands of dollars in mods. I would recommend you look at the upcoming PTP, Mazsport, Pettit Racing, Axialflow units.
6) Got the Greddy B Spec II boost controller & Greddy Type S BOV. Boost controller was a pain in the ass to set, and not very sensitive. Allowed my car at times when it was colder temperatures to overboost. Pulled that stuff off & replaced it with HKS EVC & HKS BOV. Lightyears better. Better control, and easier to set. Thought I was getting a good deal as Greddy is less expensive than other manufacturers, got junk.


Other things :

1) Got 19" rims. If I had to do it over again i would get 18" rims. Too harsh on California freeways, and 18" chrome rims are just as blingy as 19."

Overall, if I had to do it over again I would have
1. Got a real intake ala RB REVi w/Ram Air Duct or AEM
2. Got RB Cat back Exhaust (more for great sound, than hp gain)
3. Got either the SR Motorsports (with additional resonator) or RP Supercat hi flow cat
4. Kept my Canzoomer & tuned it to my car
5. Not bought rims (had 18"stockers in chrome, just would have kept them)
6. Shot myself before I got the Greddy turbo kit
7. Probably if I had wanted the extra hp just went & did the 55 hp Zex wet system like Charles R. Hill & Addictive have & shown to work with minimal problems.
8. Still got the Axialflow shortshifter because it is a great unit.

I would ahve had around 240 whp setup with minimal trouble, and spent thousands, & thousands of $ less. I have almost 300 whp now, but spent some much more time & anguish on this project.

My bad, you are correct.

wow,

words to live by.....

i have. would like to be the early guy, but i dont.... i have to fight it....

my upgrades are modest, but with attention to detail....

as i stated before the last thing i would do is pulleys...

the thing i did not do first that i regret.. lightweight flywheel....

but that is comming..

beers :beer:

peloponisios 05-24-2006 03:08 AM

Greddy pulleys as I formentioned are just for bling bling. Two of them and of course the blueish colour that we like is gone in a matter of time due to the heat, so you pay 135 for two pulleys that don't do jack and lose their only attribute that is fascinating(colour) in a week. No, I don't recommend them in any way.

EDIT: There is no web link for R-XPERT Pulley Set.

JB_Rotary 05-24-2006 10:37 PM

That ebay Greddy/Trust set looks a little shady........Description says it only replaces the alternator and water pump. The picture is of 3 pullies. I am pretty sure that in Japan Greddy and Trust are the same company or one is a sister company or something like that. Their pullies are the same size as the stock ones so their underdrive will be 0%. They are just lighter and have a magical blue coating.

speeddemon32 05-25-2006 09:45 AM

thanks, I didnt notice that part in the auction that stated only two pulleys. ebay has been deleted.

added 0% to gredy

I am also thiunking that gredy and the trust pulleys are the same. I just didnt know it the TRUST I have up there is the same TRUST as gredy's TRUST. ( TRUST is the main company in Japan, Gredy is TRUST's american sister.)

Intended for high rpm racing and only available through the Mazdaspeed Motorsport racer program for around $350. They are lighter maybe 1 or 2 lbs less (OE are steel) plus the weight of the A/C drive pulley that was eliminated (entire engine bay A/C system with pulleys, belt, hoses, condensor, etc. is 18 lbs).

Mazdaspeed claims 10 hp and frankly I'm inclined to believe it, but I have no dyno proof, just an overall seat of the pants.

Do these pulleys effect drivability in any way?

speeddemon32 05-25-2006 10:15 AM

technically yes. like a lighter flywheel you lose spinning mass, makinging it harder to take off.... but in reality no, it really just is not enough to make it hard to drive. i doubt it would be enough to even notice. (the take off, reving i am sure you do notice)

Razz1 05-26-2006 12:23 AM

What about Pettit in Flordia?

peloponisios 05-26-2006 02:33 AM

TRUST & Greddy pulleys, of course they are the same!!! My mistake that I used both firm names for the same product. Sorry!

FastRX8 05-26-2006 10:35 AM

n00b questions.

If I get the Unorthodox pulleys;
A) Do I need a different size belt? If yes, Do they provide a belt with the set?
B) Where would I get replacements for the new size belt when the time comes?

- Cesar -

kwescott 05-26-2006 11:56 AM

Looks like SR and Agency Power are the only ones that come with new belts...am I to assume that you can use the OEM belts with the other pulleys, or will you have to go out and find new belts for each of these kits?

speeddemon32 05-26-2006 02:41 PM

due to the reduction UR and AP do require smaller belts. they DO give you the part number though so you can go to any parts store and pick it up (UR)
AP comes with a new belt already. ( I belive)

kwescott 05-26-2006 03:03 PM

ghost was under the assumption that you could tighten the stock belt to fit?

speeddemon32 05-26-2006 03:12 PM

i belive no. :)

speeddemon32 06-03-2006 12:34 AM

added a link to a video of the pulley install after the flywheel was alrady on. will add a vid with no flywheel soon.

yes, it is electronic power steering. you turn the wheel one direction, and within mimiseconds, the electric motor helps you turn in that direction. :)
