And there would be no Henry Ford without Jack Daniels.

change "tuning community" to

"car show community" and i'll agree.

ask any real scion rep. the scion label was aimed at "urban youth" which has NOTHING to do with tuning in any way shape or form.

i mean, the accessories available to the xA/B "from the dealer" was pitiful.. even compared to say.. the ECHO, or go back 15 years, see what TRD made for the MR2.

so to say scion was the first.. is a spurious statement. if this were true how did all the "performance" cars appear from other manufacturers? pure accident?

how about a 200+ hp turbo car that gets 35mpg consistent on the highway?

Actually, 1991 was the 1st year Toyota used VVT-I, and that is around the same time Honda used V-tec on their cars... Honda did use V-Tec on their motorcycles in the '80s though.

In practice, a fully variable valve timing engine is difficult to design and implement. ( Toyota VVT-I is fully Variable, is changes the cam timing throughout the whole RPM range)

The opposite approach to variable timing is to produce a camshaft which is better suited to high RPM operation. This approach means that the vehicle will run very poorly at low RPM (where most automobiles spend much of their time) and much better at high RPM. ( Honda) the rsult of an effort to marry high RPM performance with low RPM stability.
Honda pushed the round rock down a hill, Toyota created the wheel LOL

So Honda V-tec is a primative way to change cam timing, Toyota had their crap together and Honda didnt.

whatd you go to ask jeeves? lol jk good info

the henry ford statement is kinda stretching it lol it was in response to screw honda not screw the guy who invented the model t

LOW torque, high hp is just crap.. i stand by my statement.

Black_Sheep_xB

I have high TQ.. Low Hp.. ( when my torque peaks, my HP starts to fall off, and TQ numbers peak higher, which is good) now to get the two to meet..hmm

I'm currently running 8psi... working pretty great so far.

I'm running the 1nz at 1bar(14.5PSI) with forged internals and strengthend block at 9.0 compression. So far so good.

Previously on 10.5 CR, may experience misfiring...

HotBox420

what kind of numbers does that put down?

richmond2000

TRD japan made turbo 1.5 vits that ran 150 HP from 7 psi, so that should be a base to start from

hey maybe this info will help out.
How about 18psi....280whp.....12.9sec...with slips and dynos.
also short blocks...long blocks.... and a place for internals
ENJOY

@1bar. on T28 ball bearing turbo with AEM FIC to tune up, its doing only 160whp. BUt good enuf for the 1nz for me...not a hardcore realli...certain gives the drivability n extra oomph when i need it..

not exactly sounds like it was a street/chase car for the tC.
reading some of the posts and it was street tuned at first while driving to and from ewvents. still a whole lot of bang for the box

Actually it is a daily driver.. Leslie drives it to and from work every day. Its the only car we have at home to get around in. Still has the built motor and turbo running 9 psi.

1 Bar and your only putting down 160???? how is that who is your tuner?

I have a mild tune on mine and im seeing 152 on 7.5lbs so lil over 1/2 bar....

what kind of dyno.

Tamago

bump for an interesting thread

JSosa

torque is MUCH more important than HP!!!
