NEW JWT IN-CHASSIS VALVE SPRING TOOL
Date:8/28/2008
 

Anyone that builds engines has probably had to do a valve spring swap in the vehicle. It’s not pretty at best and a full-on disaster if you lose a retainer lock in the engine while struggling to hold a lever arm compressor in one hand and removing retainer locks with the other. This tool allows a single technician to replace valve springs in a safe and professional manner without removing the cylinder heads from the vehicle. By incorporating a modified follower bucket to compress each spring, the retainer locks can be set on top of the follower and moved safely into place with no chance of falling in the engine, leaving both hand free to precisely complete the job. It can also be used with heads off the engine. Worth every penny at $89.95 even if you only use it once! Fits most Nissan VQ,KA,QR, &VK Engines. We also loan these tools at no charge to customers purchasing JWT Cam and Spring Sets.

JWT 2007+ G37/350Z/G35 SEDAN DUAL POP-CHARGER SYSTEM
Date:7/22/2008

Well, we didn’t think we’d do it! In 2007 Nissan drastically improved the VQ35 intake system by adding an extra throttle, so the question was, is there any room for improvement? After a full year of testing JWT got the answer, "YES", but only with the most efficient Pop-Charger Venturi inlets and hood-sealed heat shields. In addition to a 6.5 to10 WHP improvement, the tone of the engine due to the dual 6” venturis is definitely the most beautiful sound ever heard from a VQ engine!  $395 

*** UPDATE: G37 RELEASED! PRE-ORDERS ARE NOW SHIPPING!***

350Z VERSION ALSO IN STOCK

JWT TWIN TURBO FX ON THE COVER OF TURBO MAG
Date:4/23/2008

Who says you can't have it all, not Viet Nguyen! Take the world class Nissan FM chassis of the 350Z, G35, & FX, mix in a whole bunch of turbo horsepower, some awesome suspension, brakes, wheels and tires. Then assemble it all in the most meticulous way possible, that is exactly what Viet has done. We are very proud to have been a part of this project and appreciate Viet choosing the JWT Twin Turbo System to lay down the 537 WHP that makes this FX so much more than just a another show queen! Great job Viet!

DOUBLEDOWN JWT TURBOCHARGED 350Z TAKES A 1ST AND 2ND AT LAGUNA SECA!
Date:11/27/2007

Here is a JWT Twin Turbo 350Z built purely for enjoyment of the sport. Mike Bonanni epitomizes the true sports car enthusiast with a unique twist; when he plays-he wins! I think that explains his teams name Doubledown. Mike and his co-driver Scott Bush from Relentless Autosports finished the Laguna Seca Redline Time Attack Championship with a 1st place in Street RWD and a 2nd in Modified RWD. This is even more impressive considering they rolled off our dyno late the night before, with a new prototype turbo / camshafts combo, neither driver had ever run on the track before. Congratulations, on the Doubledown!

Mike Kojimas’ JWT QR25 powered Time Attack B15
Date:11/16/2007

Mike Kojima, a former Nissan engineer is at it again attempting more of his underdog magic with his newly finished B15 time attack pocket rocket. This car was originally a JWT/Nissan turbocharged QR25 street project that once finished sat abandoned in our parking lot for a number of years. Like a kid at the dog pound Mike just couldn’t resist giving this puppy a new life. And what lowly B15 wouldn’t like to be reborn like this! Just doing our part for recycling!  The engine is currently running a JWT prototype GT30 Turbo System, JWT S1 camshafts & valve spring, JWT Balance shaft removal kit, JWT Clutch & Flywheel and a fully built JWT lower end complete with JWT piston oil squirters. We'll let you know how the shake down progresses.

Titan V8 S-2 Camshafts now in stock!
Date:8/16/2007
JWT thanks Chris Forsberg for his help in the test and  development of our VK56 S2 Camshafts. Chris's VK56 powered 350Z was the perfect test bed for testing the new S2 Camshafts. S2 Cams are an excellent choice for a Titan Pre-runner or any VK56 powered Nissan that needs to run hard to the redline (and beyond with JWT Valve Springs and Reflash). Dyno testing has shown Increases of 30+WHP in the Titan truck. PART#  AVK56-N00S2 (S2 Camshafts are also now available for VK45 powered Nissans.)

JWT IS DEVELOPING VQ40 ENGINE PRODUCTS FOR OFF ROAD SERIES
Date:2/28/2007

JWT has always been a part of Nissan’s Off Road Racing development in the U.S., and now for Nissan of Mexico, as they campaign a Nissan Frontier in the Score 7SX truck class for 2007. This was a chance for JWT to work closely with the VQ40 and see what it can do. The 7SX class limits the engine to a “production” ECU and Intake system. The complexity of the VQ40’s original cam phasing and E-throttle system proved to be more of a liability than advantage and since a “production ECU / manifold must be used, a JWT Calibrated Z32 ECU and a Maxima manifold where substituted. This allows the engine to use a cable controlled throttle and locked camshafts. JWT Camshafts, Cam Dephaser kit and springs are used along with a JWT Clutch and Flywheel. JWT will be making these and other VQ40 products available soon, call for info.

Congrats to the 2006 JWT Tuned D1 Drift Teams
Date:2/6/2006

Jim Wolf Technology would like to congratulate the JWT Tuned D1 Drift Teams on a great kick off to 2006. We have learned a lot from the 2005 season and have produced a number of new Engine Combinations for '06. Unlike engine calibrations for Drag or road racing, D1 drift engines require a much higher degree of throttle responsiveness, much like street tuning. Many years of similar throttle sensitive tuning in both Rally and Off-road racing have contributed to the success of  JWT's D1 drift series products. 2006 JWT D1 drift specific products are now available including Cams, ECU, Clutch/flywheels, and more for SR20, KA24, VQ30-35, RB, and most other Nissan performance engines. Call for info and orders.

350Z TWIN TURBO KIT UPDATE
Date:1/31/2006

 


The latest on the JWT 350Z/G35 Turbo Systems:


JWT continues working towards achieving what no other company has done, CARB certification of a turbo system for the 350Z and G35. As this work progresses we have not ignored the rest of the world in showing off the new Twin Turbo Systems. Both Sport Z Magazine and Road & Track Speed invited us to put our new TT System to a shoot out with all of the other Z/G turbo and supercharger systems.


Here is what they said:



Below is the 350Z engine layout. The street kits will be ready to ship once the CARB certification process is complete. Note the intercoolers on the 350Z below. A completely integral center casting was designed to achieve a near perfect flow to the throttle tube, while using the maximum frontal area of the stock body nose. No stock parts including bumper bar or air bag sensors are moved or modified! Also note that all of the fluid bottles retain the stock locations.





Below is the first dyno session above the 6.8psi production boost, which shows off the incredible drivability of the kit. This is a kit that is specifically designed to put all of the power exactly were it can be used! Note the amazing mean hp of 310.9, this is the most important HP number for comparison as it represents the total area under the curve for the run. A somewhat useless "Brag Number" just before the rev cut, will never make you smile as much as a high mean overall HP and torque value. Keep in mind that this is still with all of the catalytic converters in place! We will let you know when the emission testing is finished.



 

700 HP SR20DET , KA24DE, RB26DET CONTROL SYSTEM
Date:7/21/2005

Turbocharged Nissan SR20 and KA24DE powered cars are reaching incredible power levels this season and require a precise control system to survive. JWT has just released this new package that will control fuel and ignition timing up to 700 HP! The heart of the system is a Ford Lightning MAF sensor, JWT calibrated ECU, and a set of 96lb/hr injectors along with the fuel rail and other needed hardware. Call for specific details and pricing. Also calibrations for Skyline GTR.

700BB TWIN TURBO Z32 700HP DIRECT BOLT-ON TURBO UPGRADE
Date:3/9/2005

JWT has released their newest and largest direct fit ball bearing turbo upgrade for the Z32. These turbos are based on the Garrett wheels and housings found on our "Disco Potato" turbo which exceeds the earlier GT25/30 in compressor efficiency and flow.

G35 INFINITI POP-CHARGER
Date:3/9/2005

G35 INFINITI POP-CHARGER AIR FILTER W/HEAT SHIELD IS NOW IN STOCK. Produces a real 6.5+ hp increase at the wheels! Hood sealed heat shield ensures outside air temperatures. This system consistently out performs extended piping systems on the G35 without the risk of ingesting water due to remote filter positioning.


QR25DE Balancer Shaft Removal kit NOW AVAILABLE
Date:3/9/2005

The Balancer Shaft Removal kit is a must for high RPM performance. The QR25DE comes equipped with a balancer shaft assembly that spins at twice engine speed to generate an opposing inertial mass. While this contributes to a small decrease in the perceived vibration, it also causes a loss of power, increased bearing loads (counter-acting inertial loads), oil aeration, and failure of the assembly itself under high RPM conditions. The balancer shaft removal kit comes complete with an oil scraper plate for proper oil separation along with an oil baffle plate to reduce oil slosh in the pan.



INSTALLATION TAKES ABOUT 2 HOURS AND IS DONE COMPLETELY FROM THE LOWER PAN COVER. COMES WITH FULL INSTRUCTIONS.



350Z POP-CHARGER AIR FILTER NOW AVAILABLE
Date:3/9/2005

350Z POP-CHARGER AIR FILTER W/HEAT SHIELD. PRODUCES A REAL 6.5 HP INCREASE AT THE WHEELS! HEAT SHIELD ENSURES COLD AIR TEMPERATURES. AWESOME SOUND, EASY INSTALL, 50 STATE EMISSION LEGAL, WHAT MORE COULD YOU WANT!

Date:10/24/2004


To update you on the JWT 350Z/G35 Twin Turbo system, we have completed development and are in the final emission cert. process. This system uses a pair of JWT 530BB Ball bearing turbos JWT presently offers for the Z32 TT. While the package is targeted at 400HP, the 530BB turbos are designed for 530HP, offering a lot more potential with internal engine mods. Check back here, as we get closer to the release. Thanks for your patience; we are sure it'll be worth the wait!

Date:5/6/2004

350Z/G35 OIL PAN SPACER KIT. Add a full quart of additional oil capacity in less than an hour! This is the cheapest engine insurance available when racing your 350Z/G35. Also not a bad option for those that never check the oil level between changes!
