is it possible for me to modify a comptech accord 04 supercharger to fix my 99 acura cl 3.0 ?? or should i fabricate a custom turbo??also are there any race engine builders in los angeles for imports such as my acura??

just to warn you i wanted to do the same thing on the same car, and the guys at Speed and Sound in St Louis said i needed an Acura NSX crankshaft if I wanted to turbo it. it is probably possible to turbo it with that kit, but why risk it. get the crankshaft first so you don''t blow your engine

There's no such thing as a COMPTECH supercharger that fits a 2004 (V6) Accord. COMPTECH (now CT-Engieering) only made/makes Accord superchargers for the 6th Generation, '98 - '02 model. The COMPTECH Accord supercharger might fit a '99 CL due to both cars sharing the same J30A1 motor. If not, then the COMPTECH '98-02 3.2TL supercharger might fit. I'd contact CT-ENGINEERING and ask.Also, I'd stay away from high boost FI solutions for Honda/Acura J series motors...not safe. Honda did not engineer lots of leeway into the design. The piston rods on these motors are thin, and the location of the piston rings in not located to support FI operation. Discussions re the this issue have taken place on sites like ACURAZINE.COM, and TEMPLE OF VTEC. COMPTECH has purposely limited their boost to ~ 4-5 PSI to avoid engine failures...some people push the boundaries & end up bending rods or trashing their transmission.There's a case to be made for not going the FI route with the J30A1 motor (in the '99 CL), and rather performing various natural aspiriated modifications:- AEM, V2 CAI- a good catback, like GREDDY, EVO2 (a Stage 3 system), or similar- COMPTECH (CT-Engineering) headers- ACURA J32A2 (i.e., '02-'03) TL Type S cams- DENSO IRIDIUM plugs (IK16)- SUN AUTOMOTIVE, grounding kit- UR, underdrive pulleys- CT-Engineering transmission cooler (preserve tranny life)...and/or...Drop a J35 head (i.e., Odyssey, Pilot, MDX, Ridgeline, RL) onto your J30 block. They mate up, and this is a relatively easy upgrade. Depending on the head you choose, you might not see lots of top end gains, but you'll see a respectable amount of low-mid end improvement in the torque department...and that's what the '99 CL needs...Honda ATs tend to have 'taller' gears.These first four upgrades I listed alone will add an honest 35 - 40 flywheel HP gain, while not terribly taxing the drivetrain. The combined cost of materials would also be ~ $2,700. You'll see ~ 40 HP from the supercharger...more torque, but the top end won't be much better than doing the various normally aspirated mods. Also, substantial power gains warrant a beefed up transmission, especially since the 'CL model was identified as part of a massive, class action lawsuit due to defective design and/or defective materials (2nd & 3rd gear clutch pack failures). A company, "Dr. Evil", does a performance transmission rebuild from the ground up for those serious about racing their Acura/Honda J series motors.Read lots of blogs & never encountered advice re NSX crank. The C series NSX engine crank probably won't fit the J Series motor...two entirely different designs...no attempt was made to make interchangeable parts. Many J series parts however are interchangeable between the like series motors...this is true across the board with Honda/Acura, like series often swaps with like.(I'm quite familiar with this stuff, it's a hobby...I drive a modified '00 V6 Accord, and a modified '06 TL)Have fun!
