Hi there I’m new to this have a question I have a jacksonracing super charger pulled out from a b16a sir (Si U.S.A) motor. I wanted to know if it can be a direct fit to my integra type r with b18c5 engine? Also if it does fit what other parts do I need to change or do to get the installation complete. Sorry it’s my first time I’m new to this I have my mechanics helping me out as well but would love to get some info pictures can be provided and we can chat from there

thanks

it'll be the same. Make sure you get all the brackets and pulleys. And you'll need colder plugs, injectors, ecu, tuning and a fuel pump.

 

Consider if the JRSC is worth the added complexity and potential issues for the power you stand to gain from it.

A well built street friendly NA setup could match it in power.

 

Only if you build a "K Series"... a fully built pump gas "B Series" engine won't even come close. The JRSC kit certainly has some shortcomings... but in it's time, it was a ground breaking product that kept a Civic or Integra very civilized while retaining A/C, P/S and Cruise Control AND providing improved performance. There may be better solutions today, but technology has changed dramatically over the last 30 years.

OP, the main difference between the ITR and EM1 kits was the throttle body cable mounting. The ITR kit had an aluminum rolling block bracket that allowed the longer throttle cable to mount across the top of the intake manifold, passing over the roller, and down to the throttle wheel... providing a sleek, low profile/clearance installation. In the EM1 kit, a simple steel plate provides a near vertical throttle cable mounting... pointing the throttle cable downward toward the throttle wheel. IF you have the EM1 kit, you will need an EM1 throttle cable to try and make the assembly work. There is a slight difference in inside cable length where it passes through the firewall and connects to the gas pedal, and hopefully, there is still proper adjustment range for things to fit appropriately at the throttle body end. The hood line on the Integra is closer to the intake/valve cover than that of the EM1, so you may also experience contact between the throttle cable and the underside of the hood. If you use the EM1 installation instructions, you will have to rotate the oil cooler 90' counter-clockwise and create a pair of loosely looped 1/2" coolant hoses feeding it on your own... this step is not found in the instructions.

 

I'll disagree with you there. I consistently see JRSC builds making only 220 -> 235WHP, with rare exceptions that exceed 250WHP with a lot of supporting mods including a NON-LEAKING LHT cooling jacket. A street friendly B20V build can survive on 93 pump and make that same 220-230WHP with something like 12.5:1 pistons and Pro 2 cams, good bolt ons.

This is purely anecdotal, but personally I've seen more than enough from people using JRSC over the years on Hondas to conclude that they're simply not worth it. Sky high IATs unless you're using the LHT intercooler, and I've seen more than a few people struggle with water leaks on those.

Combined with the fact that the JRSC kit is expensive, now very antiquated, hard to find replacement parts or support for, etc... Just not for me I guess.

 

A Type R engine with a JRSC, in my experience, typically makes between 240 and 265 WHP. A GSR with a JRSC makes 235 to 245 WHP typically and only a B16A with a JRSC makes 220 or less WHP. A clean used complete JRSC kit will cost LESS than the internals necessary to build the B20V that you have suggested above. In my experience, 220-230 WHP is "Rare Air" with a built "B" series engine... 205-215 WHP is far more common in my area.

Don't even get me started on the LHT Intercooler... they are definitely not worth the risk of failure.

As for your last highlighted statement above... I agree with EVERY WORD. A clean used kit can cost as much on the used market as it was brand new back in the day (this is likely due to the demand for a QUALITY FIT product that keeps the creature comforts of these cars in place), replacement parts are nearly impossible to find, not to mention that aftermarket replacement parts are substandard with respect to the quality of the OE parts, and the tech is definitely antiquated.

You know I am a supercharger fan... and given the advances in supercharger technology today... a JRSC wouldn't be my first choice either.

 

I ran a JRSC on my Type R about 12 years ago, even then parts were becoming hard to come by. As already mentioned you’ll need upgraded fuel pump, colder spark plugs, upgraded injectors & an ECU. At the time I ran a Hondata S300V3 & was very happy with it.
I had a custom step pulley made to upgrade to 8 psig, Intake temps still got pretty high but I had a good tune on it.
An Lht header with a custom Kteller exhaust system worked well. Tuned it made 225hp to the wheels & it was an absolute blast to drive. The blower whine & instant power/torque was awesome.
