beretta gtz parts

[tvc3-gtz]

I have heard somewhere that you can convert a normal beretta gtz q4 h/o engine from the 180hp version to the 190hp achievea oldsmobile version.. if this is true.. I want to buy these parts and have my engine overhauled.

- w41 engine components (i believe thats what they are called)
- custom burnt chip
- ceramic coated headers
- new clutch (old one at less than 40%)


BTW, also seriously looking to buy a Beretta Indy (teal or yellow IDC)
- needs all decals intact
- kinda want a sunroof again (miss the old sunroof)
- auto trans. so the fiance' can drive too (cough* still love 5 speeds though hint hint)
- condition can be fair, can need work if reasonably priced

oh and interested in an oil cooler too for my gtz, the old one looks terrible

The W41 came are pricey. I have a extra set but they aren't for sale..

Maybe try the Quad 4 forums for the Quad related parts you need.

w41 cams? oh boy yeah those are part of what i am looking for.. that cant be all i need though can it? the cams give an extra 10 hp?

[speedy]

cams and chip pretty much, the pistons dont really do much, although they do have 4 valve relieves in them rather then the 2 valve relieves our h.o's have. throw in a header you can gain another 10hp, so your at 200hp if everything is running the way it should, port and polish the head, port the intake, put a 2.5in exhaust on their, eliminate the cat, flowmaster muffler, and you'll almost have my set up... throw in a 3.94 trans and low 14's shouldnt be an issue...

Header and exhaust is the biggest bang for the money you can do. There was a guy that gained 20hp(dyno) to the wheels with a 4-1 header on a W41(stock) equipped car.
Ron Seibenick on quad4forums.com do make those header. But you can tell that your car will be pretty damn loud with a header then. I ran a 4-1 header on my old quad with the stock exhaust and it was loud. I swapped to 2.5 inch exhaust w/cat and dynmoax muffler and it was so loud at WOT that it scared other people walking down the street hahaha

loud as in badass or loud as in subaru obnoxious??

w41 cams? oh boy yeah those are part of what i am looking for.. that cant be all i need though can it? the cams give an extra 10 hp?

Believe it or not, YUP. The cams are the secret to the extra 10 hp. Higher lift and duration.

[tvc3-gtz]

can you buy better aftermarket performance parts (ie. performance cams instead of stock w41 cams)???? and if so would it gain additional hp on top of the "secret" 10hp that SGR is talking about. BTW I am glad I am such a Quad addict.. .. imagine that

hey SGR?? doesn't it hurt your performance to take the CAT out of the exhaust system due to less back pressure? if so what is the best method for maximizing performance while replacing the exhaust system? free flowing cat? stocky? 2.5" exhaust? I want the car to have a respctable menace to it when it runs, of course after the headers are purchased and the cams are found..

god..

k.. promise last questions guys..

whats the best clutch for my gtz? I may need to "eventually" replace it. (band for my buck.. not too excessive)

[tvc3-gtz]

any updates for me? if u know the answers to the questions above plz help me. thnks

If you take out the CAT it does not hurt performance. It even helps and you feel little more power.... Well thats what i felt when i took the old cat off with my stock exhaust.
I think a good exhaust is 2.5" from downpipe with performance cat (magnaflow or racing cat) all the way back to the muffler. I know you want to have a cat in there because if not, its pretty ricey and loud. UNLESS, you put a glasspack in place of the muffler and stay with stock exhaust size. Nice, louder sound and only gets little raspy at 5k rpms or so. I have a video of my old gtz here: http://www.youtube.com/watch?v=uHP0hzSQCFU
I have to say i like this setup the most(of my exhausts). But thats not that much for performance, just to have a nice sound.

But if you want to have nice performance and gain some HP then you really should go with a header and 2.5" exhaust with cat and one or two mufflers to keep it down a little.

Best clutch... well there are many choices. Spec clutch 1-4 or so but they are more expensive and got told they are not that streetable anymore. I think if you like your clutch you got in your car then you should go with a stock one again. Also if your car has more power than stock with cams,header,exhaust in future you dont have to worry about the clutch... it will hold up the more power.

[tvc3-gtz]

stock clutch will take extra power fine??

[michi]

I say yes. I dont had any problems at all and my car had header+exhaust and w41 cams and mostly beat the crap out of it, lol
Just depends on what your doing with that car... if you daily drive it and drive it on the road and have fun or you do alot of drag racing. If you do alot of drag racing and plan to do more mods to that car, like turbo/supercharger then you should go with a spec clutch or so. If you dont plan to do much more power and keep it N/A then stock clutch will be fine.

I do have a spare set of W41 cams, but I need to measure them to make sure they actually are W41 cams, cause I cannot be sure of that. All I know they look tiny bit different than HO cams.

I'm using 224\430 cams that I cannot recommend to anything else than track usage, even if these are mild for performance cams, stock ECM has hard time to figure them out even with tuning. (mostly idle sucks)

[tvc3-gtz]

if they are compatible.. how much? I'd be willing to consider buying them now just to have them.
