Na Power Results - All N/a Engines

[MissR34]

I have a 1999 R34 GT (manual) RB25DE

Put out 101.8 kW fully stock then put on a full Trust stainless steel catback exhaust with 80mm tubing and 115mm tip, and a full cold air intake kit (with a Trust Airinx pod filter), did another power run and the car jumped up to 118.7 kW. I thought that wasnt too bad really!!!!

new power figure

dyno dynamics

modifications: standard panel filter, coby extractors, 2.5" cat and 2.5" cat back exhaust, matty spry tuned safc2

power: 115.4rwkw

consensus: panel filter and an intake idea and i'd be done. wouldn't recommend going any further with power mods, despite the coolness of cams, cam gears, port and polish - costs would be astronomical for minimal gains, you would also be looking into a proper ecu to make the full use of them. extractors dont give any sort of peak power, but driveability and fatter mid range is very noticeable. with the retune reving is much smoother, power delivery is nice and "free", definitely a much better car to drive. peak power is only a number.

future mods: would stick to drivetrain mods; lightened flywheel, shorter diff ratio, lighter tail shaft - try to make the current power more useable.

does it have to be skyline...... 98 3.5 v6 Mitsubishi verada (4 speed slush box auto) with pacemaker extractors, lukey muffler mandrel bent 2.5 inch system + unichip = 130fwkw

interesting figures,,,

for the record mine was totaly stock at 200.9hp (149kw)at flywheel and 140hp 104kw.@wheels(6500revs)

with 150lbft torque @ 5400 revs

from the comparisons on here and given that was stock with new plugs, thats quite high suprisingly.

[Guardian_aiur]

I know its not a nissan and not a skyline.... (i'm on here looking for power figures of NA 6's... actually in the market for a 350Z to modify NA style...)

My N/A BA XR6 Falcon puts out 194.3rwkw... @ 6800rpm

(192rwkw @ 5800rpm)

Currently has -

Nizpro CAMS

CAPA flash tune (by Nizpro)

Custom Twin Throttle Body setup (2x 70mm TB's)

Nizpro Custom Extractors

BF Turbo Exhaust

to Come -

Compression increase from 9.65 > 10.4

Intake manifold Phenolic Spacer

Individual Throttle Bodies (6x 45mm)

Port and polish

Custom Zorst with twin 2.25" metal cats

Retune...

for those who don't care about the falcons but are curious, the Barra 182 Engine stock is a 4.0L inline 6 with 182 Fly wheel kilowatts.

How much should I expect from similar mods on a VQ35DE?

Cheers
