JWT 450hp Upgrade???

[lukekobi]

Can anyone give me their opinion on the JWT 450hp upgrade? I was thinking of going this route but would like some feedback from those of you that have tried it before I spend the money.
Thanks

[bubbleguinea]

well---its 450hp....

how much is it?

is that worth 450Hp to you???

[lukekobi]

I am curious about the driveability? Will it still run smooth with these upgrades?? smoother than stock? rougher? These are the things I am not sure about...what will it do to fuel economy?

[indy83turbo280zx]

I'm really curious about this too. I hope someone gives you a good, honest answer.

The following is info from the JWT site for those that have to ask $$$ and what's involved questions. http://jimwolftechnology.com/wolfpdf...%20UPGRADE.PDF

BASIC UPGRADES FOR THE 81-83 280ZX-T, and 84-89 300ZX-T
Stock 280ZX-T HP = 180 @ ~ 6 - 7 PSI
Stock 300ZX-T HP = 200 @ ~ 6 – 7 PSI
Add JWT upgraded ECU can run about 11 PSI = ~ 225 HP $595.00 exchange (core deposit $500.00)
(Must use a boost controller to go higher than 6 - 7 PSI)
Manual boost controller kit $149.00 ($100.00 w/ECU purchase)
Greddy Profec B electronic boost controller $420.00
HKS standard compressor bypass valve (recirculation valve) comes w/weld flange $100.00
Add your own 2.5”-3” exhaust system and an intercooler system (see HKS for the 280ZX-T,) will allow you to run ~ 14 -14.5
PSI = ~ 260 HP.
Spearco intercooler system for 1984-89 300ZX-T (this is a complete kit, 88-89 requires some modifications.) $1195.00
The original factory injectors will allow a maximum of ~ 260HP due to their 259cc flow rate.
For more horsepower than the above system upgrades can do, use our 450HP Control System Upgrade. See the following information sheets on our 450HP Control System for more info on this system.
450 HP ENGINE CONTROL SYSTEM UPGRADE FOR
1981-89 280ZX/300ZX TURBO
Description/Parts List
Purpose: This conversion is required when horsepower requirements exceed the limits of the stock injectors
and flow meter. Note that a working knowledge of the control system is required before attempting
this conversion. This conversion is not intended for applications subject to specific emission
control requirements and should not be used for such applications.
Parts needed:
1. We supply 420cc injectors. On 1986-89 300ZX-T you will need a fuel rail set from a 1984-85
model that uses top feed injectors.
2. We supply 6 dropping resistors. Note: 1981 already has dropping resistors and doesn’t need them.
3. We supply the Ford Mustang Cobra MAF and harness adapter plug.
4. We supply the MSD 43 GPH inline fuel pump for 81-83 ZX-Ts. Use 90+ 300ZX-T for other Zs.
5. We supply a note sheet along with the conversion parts to explain the steps of installing some of
the parts and some other required changes.
A few of the following parts must be obtained on your own:
1. You supply an ECU from a 1988-89 300ZX. See additional info. page for useable part numbers.
2. If you have a 1982-83 280ZX-T, you supply an “encoder disc” from a 1984-89 VG30 Distributor.
(This is under the distributor cap and dust cover. Mark which side is up before removing.)
3. If you have a 1981, you must also convert to a 1982-83 distributor and drive.
Additional Parts Recommended to Obtain the Best Power Gains:
1. Turbocharger upgrade: The Wolftech Sport 350 (350 HP potential,) is a bolt on. The Wolftech
Sport 400 (400 HP potential,) is a bolt on and requires a larger inlet hose. We now have a
Wolftech Sport 450 Turbo (450 HP potential,) call for current price.
2. Boost controller: We have a basic manual boost controller or an electronic boost controller.
3. Intercooler kit.
4. Free flowing exhaust system.

QTY DESCRIPTION Part No. PRICE
1 Upgrade and convert your 88-89ECU core $595.00 exchange
6 420cc injector IZ314-40000 $100.00 each
6 Dropping resistor (6.8 ohm/10 watt) IRES6-6OHMS $3.00 each
1 Ford Mustang Cobra MAF w/harness adapter IMAFC-COBRA $325.00
1 MSD 43 GPH fuel pump (use on 81-83 Zs) IPUMP-MSD43 $168.80

[bubbleguinea]

there are people on this board who drive cars like that everyday...

my car, proobaly around 210-220 to the wheels (based on 1/4 mile times) is my daily driver...

a fully restored 2+2 that i drive 20 miles to college every day, plus work. its my only mode of transportaion...

no matter what you do to the car, if you maintain it, it will last...and yes, its a sports car with a sport tuned suspension, so yes, its rough.

[McAdam]

for the price, megasquirt has it beat.
