20v Silver or Blacktop???, Curious? Options

[CeliNProgress]

What up everybody? Hope all is well. OK, I already did a search and only some questions were answered. I found this site called "Ray Hall's Turboing Charging" which is out in Australia. He took the 7afe block and put a 20v 4age silvertop on it. Then threw a Garrett T25 Turbo on it and the car was at 300 HP!!! This was in a MR2, but I'm sure will be the same in a Celi.

Now, I read about you guys saying that the blacktop is better than the silvertop.
If you guys could checkout the site and then get back to me. That would be great.
Just type in Ray Hall and it should come up. Le'me know.
Aight

I 4got to mention when you get to the site look under "TURBOCHARGED CARS".
THANKS

The blacktop head is far superior to the silvertop... along with the blacktop ECU and sensor set-up. I don't know exactly what you want to know... but that's how it is. Either head will work great for boost... 3 intake valves with boost will be pretty awesome. Just because one guy did well with a silvertop head, doesn't change the fact that the silvertop head is quite inferior to the blacktop. Doing the same setup with a blacktop head will probably yeild more power.

We set Kwanza equal to E-Bay, lol.... but it's so true.

Yea, don't use a silver top head. you will pay loads for it, get gains which are not that spectacular when compared to a properly set up large port (or even small port) 4ag, and with the US spec 4ag head you will be able to go to local toyota for parts.
