Whats the difference between these two? And I was wondering if someone could tell me some places where I can get info about Turbo kits for the prelude. Thanks

 

If you want increased performance and minimal maintenance get a supercharger. If you want to have pretty much unlimited hp, within reason, go for a turbo. There is an F/I forum if you want to do a search there. Jackson racing makes superchargers, Fmax and drag make turbos.

 

Both use the same basic principles. You force more into the combustion chamber than you can draw in through natural aspiration.

Superchargers use a belt to drive them, and the LRSC look similar to a... well, sideways "fan"... corkscrew looking blades sorta thingy. Goddamnit, I know what I want to say, I'm just tired right now. Anyway, the belt drives charger giving boost and eliminating turbo lag because it's belt driven... no waits.

The Turbo has basically two "fans". One sits on the exhuast side and when the air comes out of the exhaust it turns the first one that's connected to the second one that's on the INTAKE side, which forces more air into the motor.

OK, basics: They force more air into the motor, ones belt driven, ones driven by the exhuast. Supercharger gives more even power, is usually a little more street friendly, and the turbo (because of lag) may not be as quick off the line, but makes more power up top that more than makes up for the lag.

 

If you live in CA.... the ONLY legal FI system that I know of is the JRSC. The FMAX system does not comply wtih CARB = Illegal.

Also, if you drive an SH... it seems the turbo kits do NOT work with ATTS, which means the totally cool active torque transfer system will shut down when boost is engaged. From what I have heard talking to the JR people, they have an SH with the s/c bolted on and NO ATTS problems at all.

for me, living in CA, being in "law enforcement" and wanting to follow the rules, and having an SH... I would go with the s/c.

a recent review I read in a miata magazine did a nice shootout between a JRSC and a turbo system for the first gen miata. While the application is different, the characteristics/differences/pros,cons are similar.

S/C - way better off the line power. s/c car will pull away from the turbo car off the line. reliability is far better. simpler installation. overall power not as high.

Turbo - has some lag, doesn't launch as hard off the line. more difficult install, not as trouble free. higher peak horsepower. on freeway, turbo car will walk away from s/c car and s/c will NOT catch up.

if you want to play around on sruface streets, race people light to light, have a torque curve exactly like your stock car, just increased.... the s/c is for you.

if you want a car that winds up and then blasts off like a rocket... get the turbo. in a rolling start race, a n/a or s/c car will have a hard time beating you.

oh yeah... they are both $$$. not cheap mods. be prepared to spend several thousand.

 

Ive considered both the JRSC, DRAG TURBO. But after looking at both, and my friend having a supercharged type R... I would say neither. NOS is the way to go. If you do it right it will be safe, perhaps safer than a turbo, and is only abouit 500 dollars. JRSC dont give you much horsepower, about 220whp at most, and turbos will give you about 240-270whp, while NOS you can add 50-75-100... With money being and issue and no money to tune the turbo, id opt for NOS, just as fast or faster than a JRSC and only 500 bucks

 

Hmm.. How does nos work? And you guys said that turbo needs a lot of tuning? What do you guys mean by that? Are you saying that they have a lot of problems with Turbo?? I talked to a guy from Jackson Racing he told me from stock which is about 175whp to about 230 or so. I also talked to a guy from greddy and he told me that they are goin to come out with a turbo kit for the 5g lude in late 2001 or early 2002...

 

23109VC: Oh yea I have a question? I have a greddy evolution can cops just pull me over for the sound? I am not 100% sure but I think Greddy cat-backs are street legal?

 

Unless you're really thinking about running the strip I wouldn't mess with NOS. IMO, It's more trouble and riskier than it's worth on a street car... I think most of the guys around here will agree. As far as the tuning goes, JG can answer that much more completely but there are a lot of little things that can be done to make a turbo run at it's optimal level. More adjustments mean more time and more of a chance of inefficiency.

 

how does NOS work? if you go to http://www.turbomagazine.com there was a tech article on the basics of NOS... good introductory piece... go check it out...

 

Tuning is going to be involved in almost any major power buildup. Turbo, supercharger, NOS, whacked *** N/A setups...

Fuel is probably the most important in a NOS setup. Nitrous basically cheats by sneaking in an extra oxygen molecule, causing more *bang*. Now, more O2, means you need more fuel to keep it from detonating and heating up causing pistons to burn, valves to burn etc. Nos is generally harder to predict because you're working with a gas. If it acts right and acts the same each and every time, then you'll be fine with a good motor buildup, and some juice.

Boost: ahh... fun. Working off the same principle, more air = more bang, boost just shoves more air in the motor. Tuning is a bitch because you have SO much air moving in. Unlike n2o that shoves the same amount, turbo will shove different amounts of air depending on what rpm and how it's spooled up etc. Superchargers for the same reason, however they're a touch easier cause of the smoother power buildup and the peaks aren't as high.
