Anyone have any experience with GUDE cylinder head packages?

I am probably going to get one for my 94 DOHC. No, don't tell me "Do a bpt swap etc. etc."...I am sticking with the stock platform and the reasons are my own. My only questions are: does anyone have any experience with the Gude cylinder head packages, and if so, about what % power increase should I expect? I have heard as much as 75 horsepower from the new head, cam, and throttle body along with an intake, headers, and full exhaust, but experience speaks louder than equipment manufacturers. I am going to rebuild my engine, and I thought to myself "Meh, why not get that cylinder head, cams, and tb for it too," so I anticipate the drive after the rebuild will be fun, as I will have brand new engine specs and a better breathing top end.
Any input would be cool. I am NOT doing a bpt swap so don't suggest it. ^_^ thanks!

in boosted form it could be possable given if ur in a race setup like mine. in n/a form no where near that. maybe 10-20 whp in n/a form

I have to agree with limegreen mx-3 here, it is unlikely you will see more than about 10-15whp on a B6 motor with those mods in NA form. The B6 motor is not a performance NA motor like the B16 and B18 series from Honda or the 4AGE series from Toyota.

Boost is where the power is on these motors.

i dont know.... i know vaughn has alot of mods on his sohc 323 and it has a decent amount of HP. I think SINCE the DOHC is pretty much the same engine as the 1.6l in the miata. you could look @ the gains from engine work on NA miatas

Yea I was going to say...I mean, we are talking about a fully ported and polished, higher-flowing cylinder head, performance camshafts, and a bigger throttle body...I think 15-20 horsepower might be a little TOO conservative of an estimate.
What I think I am going to do is just dyno the car before and after! Because I kinda want to do this regardless, and what better way to know how much horsepower it made then by actually checking? Would be interesting for sure.

i would also like to see the before and after shots. if this adds a nice amount of power id love to do this as well since i live in cali and cant do a engine swap. keep us updated

by all means go ahead. I know im still trying to prove what a stock internal BP-De in boosted form can break into the high tens. maybe low 11's in the 1/4. im already at a 12.4@118 on a BP-DE boosted mx-3.

Well alrighty then! I am doing a few different things, so I will go ahead and get the car dynoed before and after the engine work. May be a few months. I will keep you guys posted.
