Hey, guys I've just got a few questions on a greddy turbo kit vs. the JRSC.

Greddy says with only 6.5 lbs of boost their kit will run about 50 horses more than stock. Even more with a FMIC.

Jackson Racing (Street kit) pulls something like 250s at the wheels with 5psi of boost with Hondata reflash.

The turbo runs for like $2400 and the SC runs for like $3300 w/ programable ECU or like $2650 w/o.

I read about some problems with rods and sh@t blowing out of hoods when boosted above like 7psi.

I really don't feel like dumping a sh@t load of money into my engine rebuilding the bottom end with new f@cking internals to handle more boost, cause I'm putting on a body kit, cf hood, JDM lights and Eibach lowering springs soon. Thats running me like $1600 w/o paint. I just want so more reliable power so I can keep up with my friends. 200 at the fly wheel isn't cutting any more. I want like mid 200s at the wheels.

First of I'd have to go street version on the SC for new F@CKING inspection laws! But i'd probally go with a programable ECU so i could later up greade to bigger fuel injectors and smaller pulley.

Advice from anyone with a JRSC or greddy kit would be appreciated highly, thanks alot.

 

I have the greddy kit on my 02 Si and i think it's great... The only thing i would tell you to do is definatly get it tuned... you can e-mail Steve Taylor :
steve@tech43.com... He is the one that advised me about my car. He told me that you can handle as much boost as you want on stock as long as it's tuned right...and with all the necesities...FMIC, BOV, and the rest comes with the turbo kit...

Get in contact with him anyway. He really knows his K-series Motors...

 

i have ZERO experince with forced induction on k-series engines, but i do have a ton of experience with adding forced induction to other cars.

there are a few things that i've learned from the past that could help you.

first, do the research. you HAVE to know what forced induction is all about. you should lnow the effects, how all the individual components work, what the pitfalls are, etc. the more you know about how this stuff works, the better it will run, and the less it will cost you overall. if you don't, you're going to risk the consequences.

second, make a target. this target will be the amount you are willing to spend and the amount of power you want to make. they are both dependent on each other. the more power you want the more money it will cost. this pre-planning will help you avoid hidden costs later. boost is VERY addictive, and you have to think reasonably about realistic results.

third, make a list. one form of fi may cost more than the other, but what is included? can you install it yourself? do you want to? i've had a greddy turbo kit on my miata, it ran great, but there were a LOT of other things not included in the kit that i had to account for. my fabrication skills are pretty good. i can design, weld, and assemble my own stuff. even so, it was a LOT of work to get it to work at the level i wanted to SAFELY. wound up ditching it and am in the process of adding a JRSC to the same car. this is going much better. why? well, there is a lot of owner support...other car owners who have done the same thing, so if i have questions, i can go get answers. you should find a group like this no matter what you do. internet boards are great for this. also, jr has assembled a very good kit. sure it's not the end all beat all, but i'm going to hit my power target with a reliable kit that included EVERYTHING with good customer support. the greddy kit gave me the basic kit and i had to source my own fueling controls, fmic, fmic piping, and timing controls. their customer service was practically nil.

fourth, you have to consider the power and the delivery. will the stock clutch take it? can i afford a new clutch? is my car prepared to handle the extra power? turbos have lag, it can feel like an eternity waiting for it to spool up. superchargers offer linear, transitional power. it's easier to control a supercharger power. the turbo can make more power, but if you boost into a corner, you can get a spike of power when you don't want it. the turbo i had on my car was awesome! it was fun to surprise cars with that kind of power, but the handling changed because i couldn't control the power as well, it was exponential. plus the supercharger gave me better throttle response and the power "down low" i was looking for to pull out of corner or leave from a standing start.

fifth, consider driveability. if you disconnect the s/c, you can still drive the car. you can't really do that with a turbo. s/c kits have better daily driving characteristic becasuse they have a linear power delivery. turbos can offer more power, but they are more finicky. turbos add a LOT of heat under the hood, especially in a situation like the k-series, where it is mounted near the firewall. the s/c on the k-series is up front in the cooler air flowing through the grill.

sure, i'm biased towards a s/c. i've been down the turbo-kit route. i know what it takes. i like the power, i don't like the maintenance. the s/c gives you added power and just lets you DRIVE.

 

Bravo!!! (clapping loudly)

 

Thanks for your imput guys, specially, Kung Fu Grip. The cars obviously daily driven and I have to compete with winter since I live in NY.

I like how sc have no lag but since they're belt driven they take power to make power.

Turbos are such a temtation because who doesn't love a nice loud bov. and 20+ lbs of boost.

I know with the B-series motors with turbo v-tec, after like 10K miles they start blowing black smoke. Is this true with K-series?

Although JRSC is more for a kit I pretty sure that is what I'll go with. However, since I have to deal with the winter I was wondering if anyone has problems with sc in the cold weather?

Damn that bov... my friends 2nd gen Tsi AWD talon has an Greddy bov thats loud as a mother f@cker!! It pisses me off so much when were going light to light or stopped at a light when he phssssssssssss. Plus, he can walk me in a quater so that just adds insult to injury.

 

i've had the greddy kit on my rsx for about 4 months now. let me just say taht it's been the most joyable 4 months. proper install with k-pro and u cant go wrong. i boost around 10psi daily and have had no problems. jsut make sure you learn as much about FI as you can and ask questions. also with the greddy kit, it's almost like having a supercharger cause teh turbo spools up so quick. it's a proper size turbo for our app. and has great midrange as well as top end

 

well said kung fu grip in my opinion i would also have to say the JRSC. I like the low end torque and linear power. My type S is a daily driver so all around it just makes more sense. Sure it is not as powerful as a turbo kit but if you are modding just to keep up with your friends, do yourself a favor and don't.

 

there are other turbo kits beyond the greddy, obviously. you're going to have to pay for it, though.

also remember this: if you have problems with the car, powertrain or whatever, you're not typically going to be able to go to a dealership or normal repair shop for help.

for the winter, you can do one of two things: get a good set of snow tires and use the go pedal judiciously, or don't drive it ...get a salt sled to drive during the winter months. the car will still be driveable in the snow, either way.

as for your friend's talon...i know, the bovs are pretty cool. there was nothing cooler to me that pulling along side an sk2 or mustang, changing gears, popping the bov and watching the other driver's eyes bug when i would start to pull.

all cars weren't created equal. you're friend may have a fast car, but you won't have to deal with weak transmissions, 8+ cv joints, and all the other "joys" that come with owning a chrysler/mitsubishi product (former omni glh owner myself). just be yourself and love what you have, not what you don't.

 

How bout goin All Motor???
Take a look at Todas big Cam kit. Makes great power, and you'll definetly shock other drivers. Sh*t, you could even pop ur hood and tell them you've just got the basic bolt ons. and then to see their eyes light up when they get smoked!!!

Me PERSONALLY, wouldn't run any charger if you plan on driving it in the winter time. I'm in MN so we get salt and sand on the roads. X-nay and the winter drive-ay.(for ME) Spend $1,000-$2,000 and get a winter beater and then dump it in the spring for the same amount, maybe even more??? But then you'll have to find another one in the fall. Just take a look under the hood of you car this winter, or if you can remember how it looked last year when you popped it to add washer fliud.
Or even now, How dirty everything is at the moment. Now imagine it with salt, sand, slush.... Uh!!! man i'm i glad i got a beater!!!

and that's my .02

 

all motor costs are exponential. the yields are less, also. you can get the power but you sacrifice driveability and longevity.

i used to live in michigan and i agree with the salt ride theory, just hang onto it, tho. no need to buy and sell a car every year. having two cars helped my insurance rates go down, but ymmv.

 

Not to be rude but if you are gonna put on some sort of FI you should be prepared in one way or another for problems. 7psi is a lot for an SC and i think you'll definately be happy with it. for the money a turbo is the best bang for your buck though i think the JRSC is a safer route. If you are a daily driver and looking for a little more speed then you might want to look into some NA mods as some of the others have suggested. However, you might want to draw up a blueprint of EXACTLY what you want and how much you are going to spend on your car because modding is addicting and before you know it you have put way too much money into the car.

 

I'll have to agree with silver comet. Plan out what you wanna do 1st. You can go all motor and get to the 230-260 at the wheels with out sacrificing reliability. Just
remember what you are tryin to ACCOMPLISH.

I've got a friend with a Greddy turbo'd b16 EK, WAS putting out 260hp at the wheels 14psi. WAS...
looks like 260 wasn't enough because he just upgraded the greddy turbo and exhaust manifold to try and reach 350hp at the wheels. From the get go, I told
him the greddy kit was not gonna do it for him as for as power gains go.(For HIM)

You can only TRY and have a plan.
Before you know it, you will be spending more $$$ than you originally wanted...

As for buyin a beater, than selling it, I not saying to do that!!! I'm just sayin if you are strapped for cash, save some money now, buy a beater in a few months, come spring dump it for what you paid for it and spend the money on something else.

 

The problem with all motor is its so expensive to make the kind of hp i'm looking for. Plus, all motor is not upgradeable like a turbo or sc. So if I want even more power its not as easy as a slapping a bigger turbo on or smaller pulley.

If going all motor, what mods would create about mid-200s at the wheels, with-in the same kinda price range as the turbo kit or jrsc. (About $2000 towards all motor)

More agressive cams and gears, port and polish the intake and exhaust, maybe a type r intake manifold, bigger fuel injectors, hondata k-pro, underdrive pulleys, flywheel, maybe stage 2 clutch or something...

What would you guys suggest for an all motor?

 

if i were to go the motor route, i would start with a a k24.

not a fan for cliches, but there's no replacement for displacement.

 

Yeah, yeah, yeah... I read the articles on a K24 swap with the A2 head. But giving up an almost 8000 redline is hard. Sure moce displacement, more power w/ boost, can use **** gas, but a swap involves alot of down time for my car. Not to good when its my only source of transportation and I have to get to work and school.

 

with the smaller engine, you going to have to wring it out to get the power. the higher displacement gives you a little more 'bottom'. if you're going to fret over fuel economy, you need to just get another car that comes with a bigger motor.

a swap would be less downtime than building up the motor already in the car.
