i think matching a fe3 profile to that of a popular/proven 4g63 cam would be a good idea as well, since the motors are fairly similar

I think so too. I have a book showing dyno proven results of 4G63 grinds showing higher and lower dynos using a cariety of popular grinds. Same car, same dyno, same boost. I'll snap a picture of it and the specs of all of them.

no [shizzle] my friend told me they were rare only like 300 made i think he is just dumb

Yeah but howold and beat up are the turbos by now. Buying a used turbo is a gambleto begin with and buying a used turbo from 1984 is even worse.

Not when the car it came off of only has 50,xxx original miles and the owner is one of your best friends.

[TurboGT]

well than he got a good deal

[zlyricist]

used turbos are hit and miss, and it helps when you know what to look for.......but i agree a turbo from 1984 is not ideal

lets see them 4g63 pics damian

wtf, WTF??

fe3 @ 050 = 240 or 245 duration, whats going on here?

the street strip 8v cam for the b2200 would be a better choice, those just seem so damn tiny, no wonder they don't flow/make much power. Or are some readings incomparable/wrong/??



something like one or all of those ^

Its funny cause I tried to do the triflow plots for the f2t and had them done but sicksix just trash talked so I just said screw it find out for your self. it is a good grind and I loved it thats all I have to say.

[zlyricist]

funny you went that far just for damian

when i talked to geoff he said you sold the car before you were able to dyno the triflow
