Anyone have any good articles that explain the relationship between turbo PSI and airflow? For example the stock turbo at 15-18 PSI (BC), my T66 at 9 PSI puts out way more then the stock one at 18. How does this work? Any good articles that explains it?

$10 on ebay you get the adaptor and even a filter!!! http://cgi.ebay.com/ebaymotors/87-92-TOYOTA-SUPRA-TURBO-MAF-AIR-ADAPTER-3-KIT_W0QQcmdZViewItemQQcategoryZ38634QQitemZ8052653676QQrdZ1 and NO the normal adaptor will NOT work on a turbo MAF

Your telling me you would rather try and make one then spend the 10 bucks to get one already made nicely? thats seriously cheap! If you keep being cheap with your mods your not gonna get anywhere! I could see if it was like 100 bucks but its 10 dollars man

just spend the 100 bucks on a T4 manifold then u can bolt anything on

I want one... id make like 5 thousand hp! but yea its kinda ugly.. does it come in chrome?

get valve cover gaskets, ditch the stock screws and use bolts to tighten them more but dont go too crazy or... crack...

it depends on if you using cork or gasket material, the cork should only be hand tight with a screwdriver type handle and socket attatched as tight as you can get it with that just using your bare hand, the gasket material your gonna have to tighten alot more and your gonna use a ratchet, if u...

its not good for a motor to backfire violently, in a NA it will danmage the exhaust valves I dunno about a turbo but its never a good thing!

Am I just like crazy or last nite was there some wierd message when trying to go on supramania.com that said the site was gonna be closed and they were gonna put up a new site for MK4 supras and they were gonna sell parts and stuff

running an open dp sounds like shit, not to mention it will backfire on you and if it backfires hard it will damange your exhaust valves, run 3 inch from turbo no cats into just a decent high flow muffler and it will sound nice

"Any gasket will be fine if the tune is right and it doesn't detonate." just drained oil it is JET BLACK and very thin, water like viscocity, it was just put in 50 mile ago, a/f was also oily and brown. I can get a feltpro for $68 then I imagine all I need is valve cover, exhaust and intake...

I have herd that stock gaskets work just as good when propery tightened with ARP studs is this true or do I need a steel one? Also is there any writeups on here about headgasket install because I have no idea how you keep the correct cam position and timing once the cams and gears are off. What...

the dipstick is NOT milky though..., its not turbo seals the turbo is new and the downpipe is dry of any oil. The thing that gets me is the oil level is not going down, if anything slighty up. Also I had this wierd thing happen the other day my temp is at normal then all the sudden BOOM the rad...

hmmm... the turbo is brand new... and I am gettin steam and even water droplets out the breathers, the oil level is not going down (if the seals were leaking it would slowly be going down) if anything oil level is going up...

Okay, im gettin constant (mild to medium) smoke at idle out the exhaust and I cant tell what color it is, but im NOT running rich my friend hooked a wideband up. When the car starts the next day it stumbles and smokes a little. I am getting constant steam instead of oil vapor out the breathers...

What would make the car run overly rich at idle, esp if I rev a little and let off? I have a new 02 both stock comp and piggyback MAFT has same problem even after the 550 injector tune down. Seems to run rich and smoke =( is there something elce that would be a factor? Also the car idles fine...

yea, thats what my guess was too but it shouldent det on 10 PSI with NA compression esp running 108 octain, I also herd that changing the timing can also change powerband higher or lower thats what I was getting at, anyone elce hear of that? that was my second guess... I could see det on 15 PSI...

Dont litter my post with your sarcasm and your im cool because I know more then you attitude. I simply wanted to know the reason behind the timing difference, and NO im not tunning my car by "how hard it pulls" I just wanted to know the reasoning behind the change. I havent got my car to a dyno...

I dunno but 0 deg runs harder on boost then 10

wow thats a great idea.... where do u get thoes!?
