Bastard 20G?

[howslowcanyougo]

Guess for me I'd rather be a bit safer than alot sorrier right now.

You'd think this Evo3 with a Evo3 O2 Housing, big flapper and new front mount should net me ~50 to 75 more HP than my old failing Big 16 and stock side mount, right?

Also there seems to be outright disagreement on this board right now, on both headgasket/headbolt standards in relation to turbo size and boost, thus I can't really feel very confident on depending on either of the answers as being true or false in my case.

Besides, I admit I'm still a n00b, and I rather learn some more before going too big and and end up just wrecking my motor.

I don't think 50-75 hp is easily gainable unless the car was just so far out of tune before. The evo3 isn't that much bigger than the old one and I don't think they will get you that much more hp.

Howie, if you want to do it right, listen to the rest of us who say you should replace the HG on a larger setup. I think an evo 16g is too small to attain you goals of +50hp. It is not much larger than a big 16g. Alpine got ~319hp to the wheels last year on his with a FMIC and dyno tuning on race gas. I wouldn't expect that out of your car as it is an auto. You would have to be the second person who made 400hp on an evo 16g to get ~320 to the wheels. There are quite a bit of possabilites of turbos between the 16g and 60 trim... I would chose a PTE 50 trim or a 20g. I think they will make you happy. I

Looks to me here like a new Evo3 would walk all over a sick big16?

And I suppose the big front mount vs a stock SMIC is worth no gains?

Guess I need a 60 trim and to blow a HG to get anywhere then?

An evo 16g flows ~2lbs per minute more than a b16g. That is a diff of about ~20hp. Here is a bit more info about the turbos:

The thread you pointed to made no claim of a signifigant diff in HP potential. In a car with a s16g and a evo 16g, I would bet on the driver. I do not see a big difference between any of the 16g turbos to justify calling it a worthwile upgrade for you.

According to this same thread, it looks like 4 lbs more per minute on the Evo3, is 40 + 25 for the new FMIC install = 65 HP gain!

What's wrong with a 65 HP gain, with a minimal risk to your motor to boot?

14B 33lbs/min
16G 36lbs/min
B16G 38lbs/min
Evo16G 42lbs/min

Stole this info from mustgofaster. Mike (vicious) stated that 1lbs/min is about equal to 10 hp so a 14b should go up to 330 hp while an EVO16g should go up to 420 hp. Not sure about the s16g though. I would guess 350 because CVD got 319 fwhp. Add in the drivetrain loss and CVD made around 375 crank Hp.

With a FMIC you could make another 20 to 30 horses I would think.

How did this get posted?


I guess I personally don't think it would be a worth wild upgrade. If I were to upgrade, I would go bigger. My GST came with a $800 FP big 16g on it and one of the first things I did to it was upgrade the turbo.
On my car with the blown HG, I am guessing the 6 bolt head might have been warped that was put on the 6 bolt since it wasn't tuned bad and it happened right away. I haven't pulled it off or done anything yet though. I guess I just cant get a good head for this thing if that is the case. It would be the 4th bad one swapped on the car and the 5th swapped in the 6 months I had the stupid car.
