i want to go s/c with my 91 si, all i really got done for power wise, is a aem cai and a custom cat back exhust. i was wondering would my aem cai still fit if i get a s/c, or would i have to go with a different intake?.

also, what shouldn't i buy or upgrade since i might not need any use of after getting a s/c? meaning like no point of getting a upgraded intake manifold because it would be replace with the s/c once its in place.

 

There are a coupls of JR s/c on e-bay right now for the sohc. One is even close to me. about 30 minutes away. If you need it checked out let me know. I was searching crx, newly listed first and they both came up today

 

If you want to go s/c call alamo autosports in Arlington texas, they have a used one for sale for real cheap. Talk to brice.

 

thanks, but the main thing is that i would like to know before i get a s/c, is would my aem cai still fit? and wat parts shouldn't i get becasue it might be replace or would be use if i get the s/c. like could i get aem pulleys right now and have it work with the s/c?

This car uses an experimental installation. The engine internals are stock except for JE low compression forged pistons. The compression ratio is lowered from stock 9.5 to 8.0. Everything else in the engine is stock, even the head gasket. The Supercharger is geared to give 22 psi at 6500rpm. The engine fuel and ignition is controlled by a Civinco ECU using one ignition coil per cylinder and larger fuel injectors. The exhaust system is the Supersprint header and a 2 1/4" collector with a 2 1/5" back system. Power is 250+ BHp (stock is 107BHp).

Holy Crap!!!




The Twinscrew Supercharger

This type of supercharger has the advantage of delivering instant high boostlevels from low rpm´s. Due to the patented screw design this supercharger is much more efficient than the roots-type. This charger can achieve very high boostlevels and still be efficient with low discharge temperatures.

Anyone ever heard of this company from sweden??!!
e-mailing today on price.

I "think" you will probably have to mod it, to get it to fit. The Throttle Body sets at a different angle, then the stock one does. Anyway, back when I was looking for a CAI to fit mine, I still would have had to hack on it, to get it fit. Thats why I ended up going with a DYI CAI instead.

 

do u got any pictures of the s/c in your car? also what parts shuoldn't i get right now if i'm going to go s/c?

 

If someone gets a price, post it up.

 

I e-mailed them this morning...still no word back yet.

Hi Jake,

We are currently negotiating a deal with a US company to market our
products. This will be announced on our website as soon as the deal is
completed. Until then we are not accepting any orders.
Prices will most likely be slightly higher than JR since this kit kontains
higher quality on everything and also includes th intercooler. These kits
are designed
to fit on 1.6L engines to begin with.

Regards, Fredrik

Ive seen the JRSC go for 2350 at this site http://www.creverything.com/cr-jacks...-chargers.html So expect that one to run 2800-3200.

22psi!!!!!

soo are they sayin that thier s/c runs stronger than JRSC?

 

I have some pics on my web site, however they need to be updated since I have added the Z6 swap, ect...

http://www.geocities.com/chipman_13

The sc was designed to run with leaving eveyrhing stock, ignition, exhaust, intake, ect... However, adding the CAI made a vast improvement over using the stock intake. Going to a header, bigger exhaust tends to drop the boost some, but it does not hurt performance tho. Just means there is less restriction.

Try avoid using the JR Fuel Modulator Unit (FMU or RRR). It tends to run a higher fuel pressure then whats really needed. The CarTech I have is more adjustable, so in the long run, it's easier on the injectors.

Sooo, your looking at fuel pressure, boost and air/fuel guages. However these are really not needed, unless you switch to the CarTech. Just depends on how involved you want to get... hehehe

 

A friend of mine owns a moblie dyno and he said he dynoed an Si rex with one and it layed down about 120-130hp @ the wheels. So, personally, i think you'd be better off going with an engine swap which would be cheaper and you'll get around the same power.

 

What was the WG spring set @?

Could make a difference. lol
