Since moving to a high altitude city (Calgary-3500ft) versus the west coast at sea level my GSR 4 door has gotten slow. I have just started to plan out a turbo build. I really wanted a JRSC as it would satisfy my power requirements, however they seem hard to find complete and not as efficient. But maybe I'm wrong! If anyone thinks I should supercharge then sway your opinion!

What I'm really after is low range torque and MAX 250 ish hp, thats where I thought the JRSC would be key, but if I can get a turbo to pick up at 2500-3000 that would be awesome as well. I don't want a rocketship, I want a reliable buggy that will push up hills with the boys to the ski hill in the rockies. If I went supercharger I know my header & exhaust is set up well for it and I would be able to retain A/C. Then on the flip-side a turbo is more efficient because it doesn't run off the belt and rob power to make some.

Either way I go I plan on keeping all stock internals, and the motor had an OEM rebuild 30,000 ago

I like the thought of a turbo. I been thinking about it myself. $3k should allow you to get some new and some used turbo parts....all quality parts. Myself...I'd buy a new turbo and injectors. I would also try to find slightly used parts for the rest of the kit.

Yes absolutely new turbo, I would get a cast manifold, intercooler, fpr, maybe dsm injectors, bla bla bla, I have a virgin P28 waiting for an s300 as well. One of my roommates and I are both welders and he has a nice tig machine so I would be very excited to do my own piping all pie cut

I keep going back and forth on either turbo or jrsc, I've never driven any FI Hondas so I don't know what to expect

IMO...turbo will boost faster than a supercharger. Especially on the GSR block. 12lbs with a T3 and injectors.....guaranteed a handful. Guys throw stg2 all motor camshafts in and they get very respectable gains.

S300

Oh snap I thought the blower would kick in earlier :S

Small turbo that spools up quick will get you the best low end torque.

I really liked my supercharged GSR setup. The car was reliable, and super fun to drive. I like how clean the setup looks on the car. If you do it right, it appears factory! I always got over 30 mpg on highway trips too. The whine is super cool, and it made power low in the rpm's. The low rpm roll-on power is awesome. That being said, it will never have the potential of a good turbo setup, but easily exceeds what the chassis of the car is designed to handle. As for downsides - on really how days in traffic, the heat soak power loss is noticeable. The alternator to blower belt is really short, and wears out fairly quickly.

Here's my build thread from back in the day: https://hondaswap.com/threads/hatch-b18c-jrsc-build.94841/

And hoooly shit, that thread is almost 7 years old

Briansol is that an S14 SR20 turbo? My friend has one and thats the turbo recommended!

99sidude I remember that build I really liked the car, did you buy your charger new? I'm still torn on both directions

 

[Briansol]

no, that turbo didn't exist in the 90's

Yeah I bought it new. I don't think they sell the kits anymore though. They can be found out there used for pretty cheap. Just make sure you get all the pulleys and brackets.

 

[GlassHeadlights]

I searched up that GT2871R for a while and it seems well suited, but it has a 5 bolt flange so I'd have to craft something up

And yeah too bad they don't make the charger kits anymore, I've always wondered if they wear out? Then would it be junk or what?

Do you want more power on a daily basis? Or is this your biggest concern? Rather than make an Integra more ski trip oriented, I'd just pick up an old V8 Grand Cherokee. Built to haul people and their crap up a hill. And if prices out there are like they are here, $1,500 will grab you a pretty good one.

I have my cherokee already haha

I went to the wrecker today and fount two turbos, first was from a late 80’s Audi 5000 inline 5 and the other was from an ‘89 Chrysler Daytona (Mitsubishi). They are both 100% stock not touched, engines look clean and they have almost exactly the same mileage

Which one should I pull?

 

[GlassHeadlights]

The Audi had this motor

The Chrysler had this motor

 

[CAFROG]

Garrett Turbo new.

I personally wouldn't choose a used turbo out of a wreck yard. But you could pull them and feel for play. Then make a judgement call. I'm guessing they're pretty small turbos but if it's forced induction on a budget Go for it.

 

[GlassHeadlights]

Precisely my plan! I need to figure out which style flanges these things have
