better get those dynoed first, then we'll talk.

Ill see if I can get a Dyno on your request.

dude wake up and smell the boost. ihow long have you had you're 20V? i've had mine since 2001 and i can honsetly tell you that the GZE has more torque than both BT and ST.. period.

Love my 4age lol 206,xxx i trust that motor enough to drive 170 +miles to autoX events & drive home... lol im thinkin i may mix it up a bit when i get my ZE, See how the old 4age handles a little boost.. lol

No doubt.
I almost got this- close...to buying a 4agze. Asked the experts and they suggested for reliability..to go for the BT. PLUS Im getting 6spd transmission with LSD

all motor will always be my favorite ...it just feels better imho ...oh and sounds better

but to be serious i am seriously considering boosting the 20v after i finish all chasis and suspension work i want to do to it

Feels better yes, much better control over power... (allthough if people put the right sized turbos on cars in my area then the power wont come on like a light switch...) i do have to dissagree i do like the sound of a boosted motor over a N/a *Import*

you're really showing your inexperience..... my 4agze has way better response than my smallport map based 4age..... all through the band... and that's with a high geared transmission.... and i guess I should add that my smallport has a 200mm flywheel on it which helps it rev over the stock 212 that they and the 20V come with....

efi is way less problematic... wiring is straight forward.... and i'd have to say the ITB's cant' be beat for sound.....

the 20V silvertop was overrated since they were claimed to be 160hp from factory

a bigport was rated at 112hp from factory... many have dyno'd over 100whp.... that's less than a 12% loss through drivetrain.... quite the opposite of over-rated

a smallport was rated at 130hp from factory.... they are slightly over-rated but once drivetrain loss is figured it's about right....

sportrally88 · 03-21-2007, 10:56 PM

okay okay ....ive grown tired of this ....maybe my opinions on N/A are tainted because of where im from(chevy is KING around here) .......and this has made me realize that boost isnt the devil but it is definately something im into .....i just dont see the point in boosting these engines because i like them for what they are

I totally disagree.

A well set up boosted car will have more torque / cubic centimiter throughout its entire rpm range than any normally aspirated car of the same size.

Besides the gze is supercharged not turboed.

Wanna see a properly setup turbo's throttle response? ... check this vid out.

Edit ... Damn I never tire of watching that vid.

ironically the latter of the 2 drivers is well known as the "drift king" (though he doesn't do circuit anymore) and has a well built ae86 that's n/a and quite quick (i think with a 20V in it, would have to watch the video I have again).....

Just like I promised

The top graph is an actual Dyno from a SIlvertop recently. That is measuring WHP folks...Yes to the wheels. BHP is just like inches, its a unit of measurement. wheel horsepower (since engine is in car) is also BHP or simply HP.

WP is something invented by sport compact car a long time ago to diifferentiate rated HP (crank) and well, wheel horsepower. But both are measured as BHP scientifically.
So this guy was making 139 to the wheels...NOT BAD.
The BOTTOM Dyno Graph is from TOyota...Measuring the BT and the ST.
The Blacktop is in Solid.

^^^ there are some problems here.....

first of all, when they were talking about dyno's they were speaking to the original poster specifically..... mainly because a) most engines will vary and b) this one will vary specifically because it's not setup for EFI and may not be tuned

secondly.... the graphs..... graph number 1.... I notice that they are using a "dastek" dyno... and the sheet doesn't say whether it's SAE corrected or not.... if not, then it could be upwards of 10-15% off.... I checked their website and found very very minimal info on their dynos so I don't know either way..... graph number 2... if it came from Toyota it was probably of the engine alone in ideal conditions, and I don't read japanese so I don't know what else it says

what I CAN tell you is that in reality and in the cars, the blacktops easily outperform the silvertops on the dyno on US pump gas... it's been proven time & again.....

JoeJITSU · 03-23-2007, 02:59 AM

actually the car is a ST with these mods... open intake, custom exhaust. I think it running a BT box, not ST its a little out of tune. ANd yea I asked the gu at speedlab and the #'s for the ST is at the wheels

micro214_kp61 · 03-23-2007, 07:50 AM

JoeJITSU... you're missing the point. like i told you at Grupo Toyota, i'm not after graphs of open ITBs and EFI, i want to see if there's a postive to going carb. i also, like toyotaspeed90said, want to know if sportrally88's set-up is tuned or how it's tuned.
