First off, I work on cars for a living, and have done so since I was about 11 years old. I've been around. Turning wrenches is putting me through college.

I've got a 2000 model Integra GSR with a B16 bottom end, but it retains the GSR head, intake manifold, and cams. It has an aluminum flywheel, and that's it. The static compression ratio comes out to be something like 10.7 to 1. I only run 93 octane fuel. The B16 bottom end has approximately 80,000 miles on it. I've been a nitrous guy from day one, but nitrous isn't going on this particular car since it is a school car. However, my new goal is to beat the newest Cobalt. I drove one and didn't like it. I always wanted one and now I surely don't. Didn't seem like a fun car to drive. The motor laid over entirely too early in the rpm range. I already have a car that's paid for, and it would be stupid to buy a car that would leave me with a note, and being a car that doesn't please me only makes it more stupid.

Here's the deal! I've been tossing and turning over the idea of JRSC and a simple header. I also got to thinking about a simple turbo setup, but i'm gonna stretch the supercharger idea a little further before abandoning it completely. Anyhow, I think 6 or 7 psi from a JRSC is the max. I can't risk getting wicked with my school car, but the older Cobalt SS's had superchargers and it was reliable also. However, they did have a cooler for the supercharger. Overall, my guess is that since the Integra is a little lighter, maybe has better gearing, and can turn more rpm's, it will be capable of beating the Cobalt with even 20 or so less horsepower. Not sure, but it could be interesting.

Do you guys think the Jackson will put me in the same league as the Cobalt SS Turbocharged, or do you think i'd be wasting my time and would always get pulled on by the Cobalt?

Thankyou in advance.

Get a B18 or B20 bottom end instead of the B16 for starters.

Not to be a smarty pants, but why?

Honda Bull

No replacement for displacement.

You're not going to want to see what power that 1.6L makes with the supercharger even. You'll be kicking yourself for not getting a 1.8L in that, especially for a broader powerband.

Not sure what you entirely want in terms of the turbo setup vs. the JRSC setup, but whatever you do, make sure you find a reputable tuner in your area and get it properly dyno tuned. A healthy B-series, with a proper tune for the fuel you're running, will take a lot to 'wick'.

More displacement, longer stroke is more easy torque.

integrawow

Well, if I only knew if an SC61 mated to a T3 style turbo manifold, then I might have a couple more options. I already have a Moroso oil pan with built in drain back bosses.

I was thinking along the lines of Hondata S300 for tuning no matter what route I end up going.

I just figured that the B16/GSR would come alive with a JRSC, but if you guys have either been or have seen disappointment with that combo, then I could only guess what would happen with me.

As long as it stays together, i'm happy. I hate working on cars sometimes. lol

turbociv910

stock TC cobalts with a tune are making over 300 WHP. Watch out, they are WAY de-tuned from the factory. But if you know its still on stock ECU flash, its probably around 240 whp.

Yeah If u can ditch that b16 bottom end. If not def turbocharge it. Im pretty sure that b16 with a jsrc would get beat......you can find 1.8 bottom end fairly easy

B16s are torqueless wonders. Even with boost. The JRSC is a big disappointment. I would tend to agree with the masses here. Get a B18C bottom end, then put together a turbo kit. If its tuned correctly there is NO reason it won't last. I drive a boosted Y8 on 12lbs daily with 0 problems. Even gets me 31 on the highway.

blinx9900

WOW, hold up, not true at all, maybe off boost yes, but on boost HELL NO!!

Dogginator

My point was that you handicapped the engine before and now you are trying to improve it.

integrawow

How did I handicap it?

Don't take the whole questioning you everytime thing wrong, but i'm really having trouble understanding what you're getting at. This little motor is useless before 6,000 rpm's. If it's below that rpm, then you're kind of screwed. The ball-sack that it loses, in regards to straight line performance, is astronomical. That's why I even considered the jrsc in the first place.

How could I UN-handicap my motor?

Dogginator

The loss of displacement by downgrading to a 1.6 liter bottom end vs. a 1.8 liter bottm end constitutes an 11% loss in torque. A B16 can produce power, but a b18 will produce more.

marcj

those cobalt things are porky in weight.. you should have no problem winning from a dig with a 250whp honda with a good setup. weight:hp ratio + torque is what wins a race.

Bseriescivic5

Dont listen to these guys telling to to ditch the b16a bottom end, its fine. It obvious you need to boost your motor to beat this guy, so stick with the b16a bottom end and use the money saved from NOT CHANGING the bottom end into a GOOD turbo/tuning setup. you can easilly get 220+tq from a good turbo setup on a b16a bottom end, and would crush the Colbolt, assuming he doesnt have a bunch of mods. Your looking at like 3000 or less for a well built quality parts and tuning setup all said and done.

Hybrid96EK

Well, thats your opinion. Look at a boosted B16 and then find a B18 with a similar build on the same amount of boost. Tell me that B16 isn't still lacking in the torque department. Its a simple concept. Stroke is going to win here, everytime.

blaze the chemi

The cheapest way to do this + the least amount of work is to stick with the B16 bottom end. I happen to enjoy the B16 when boosted. The boost and acceleration is smooth yet exhilarating. I can't stand the lack of torque especially N/A, but when the engine is boosted it happily responds.

I think integrawow could part together a great turbo kit and bolt it on and rip it. He will certainly be faster and I'm sure handle better then the stock Cobalt SS just from this and that is all he is looking for.

I bought a JRSC for my B18c and got it dynoed and was so dissapointed 210 whp i sold it after only 3k miles. my PB kit = 319whp its a no brainer and not that much more $$$

integrawow

Alrighty, how about I just leave the daily alone and take the nitrous drag integra to new limits. I think that's the best thing. It's easy to get off track and start thinking about things like daily driven cars and superchargers. LOL

I appreciate everyone's post in this thread.

philafelman

ive had a b16a and b18c shortblock in my old dc2, both with the gsr head...i did a 14.6 quarter with just intake/exhaust on the b18c....i had skunk2 I.M., cams, and portwork on the head with the b16 bottom, and could only muster out a 14.7. id go with the bigger block.

LightningTeg

Cobalt TC's are no joke. Stock they trap 103-104ish. Your gonna need at least 250whp to keep up with any modded ones.

96 GSR-T

A B16 in a DC makes about as much sense as a poop flavored lollypop.

If your heart is set on it for whatever reason you will obviously need boost or a healthy shot to do what you are trying to do, a .57 trim kit with all the supporting mods and a good tune should get the job done.

integrawow

What about a Greddy turbo kit for the daily?

Greddy, perhaps a used kit. Hmmmmmmmm, maybe. I mean it's simple enough to drive everyday. Like I have mentioned, this isn't my only Integra. I have a drag car, but I was just wanting to give the daily a little help. I guess.

Its all about preference. I've had nitrous SOHCs, nitrous B16's, turbo sohcs, turbo b16, turbo B18c. They can all be fast, its just easier to make more power on a bigger engine.
You can make 250+ on the B16 with spray, stock bottom end. you can make 300+ turbo'd. but the B18 bottom in going to respond better, and improve great with even mods.

I mean anything can be done. I make 350whp daily on a D16Y7 on 92 octane. no port work.

mrchris1979

Turbo the B16. More boost, better efficiency and just as reliable as a supercharger set-up. It's all in the tune. There is no other alternative if you want a guaranteed kill on the Cobalt. The B16 has weak low end torque but excellent top end power. It's a perfect match for a turbo set-up. The Cobalt may have a jump on you from a dig but it won't be long before you start passing him. From a rolling start, the Cobalt will never have a chance. Even if you have less HP. I've had a few races with Cobalts at the 1/4 mile as well on the highways last year. I had 270 HP on my CRX with a turbo B18c motor. Okay it's a B18c on a CRX but I still made 270HP. The higher torque from the B18c just caused wheel spin anyway so a B16 should be more managable from the launch. Get a log manifold for quicker spool, a T3/T4 turbo in 50 or 57 trim, small intercooler, 2.5" downpipe and exhaust, 8-10psi of boost tuned with Hondata S300 and call it a day. This set-up will cost just as much or less than a JRSC in used and new parts.
