Whats the max for B18B kit?

WIthout upgrades, out of the box, power/boost for JRSC vs Greddy. Is there a way to turn up the boost on the greddy turbo? If so, is it more or less efficient than upgrading the pullys on the JRSC?

Is greddy the only turbo kit that'll let you keep ur AC? (98 RS)

 

Get a boost controller and you can up the boost level assuming you have the tuning and intercooler to complement the higher amount of boost. I believe you can retain AC with Revhard and Drag kits as well. Out of the box, the Greddy turbo will outperform the JRSC on the B18B. If you look on JR's website, they only got 160 whp out of a JRSC B18B....pretty pathetic if you ask me.

 

Thanks for the reply,
Do you have any idea what boost level I can safely turn it up to without intercooling? I want to avoid any visual indication that I have a turbo. Also, at what boost level is the turbo at its maximum efficiency? How much power would I be looking at with this setup?

 

You'll also have to have your wastegate setup with the right springs so you dont lose that extra boost but that shouldn't be a problem some of them come with a variety of springs. But you should definitely go with an intercooler, as far as the hiding of the intercooler its possible with some modifying you could use a fender mounted one from a mistu or something. Even with the smaller fender mounted intercoolers you can safely boost up to 14psi. Look on Ebay for a intercooler you'll see what I mean.


Ls@22psi

 

I wouldn't go above 5-6 psi without an intercooler.

 

Most turbo kits will retain the use of AC. Its some of the higher end manifolds/DP setups that wont allow for AC.

A turbo is more efficient than a blower, but in reference to what youre asking, depending on relevant modifications, PSI is PSI, so when youre talking about 6-8 or 6-10 or something along those lines, its about the same. Past 10PSI and I believe that M45 blower in the LS JRSC kit begins to lose its efficiency.

I would turbo a B18B....I like Rev Hard kits personally. Spray the IC black if youre worried about people seeing it.

 

i had the greddy kit on my car, outta the box with the large greddy front mount i ran 8lbs of boost, towards the end i had a stock bottom end running everyday on 14lbs of boost, put out 280 to the wheels, so i think thats about 350hp, i beat the 3 jrsc'd tegs around my area, was definitly better then the blower in the long run my mods included a 3mm head gasket, afc, avcr for boost among other things, and a long dyno morning

 

BTW, SwainTec (sp?) has a matte black coating for intercoolers that actually improves heat transfer, while making the core darn near invisible. SCC used it for a SR20DET Swap into a G20 in the December 2001 issue....

 

Running 14psi on a stock block is.. less than ideal. =]

I wouldn't run more than 6-7 PSI without an intercooler, and with I wouldn't run more than 8-10PSI with minimal fuel management and no bottom end work.

Where are you from?

 

This guy has the right key to running boost safely, intercooled or not.
