I am interested in knowing what turbo cams everyone has been using. I know alot of people have posted this, but none of them got into specifics.

I want to up the performance of my edelbrock kit just a little bit, maybe get to the 200whp mark at the 7psi. This will all be done on a JDM D15b in my 94 coupe. So i am guessing that a cam for a z6 will work fine?

Also, i will only do it if i can leave the rest of the valvetrain stock. So i am guessing that knocks out high lift cams, or does that knock out longer duration cams? I really don't know, so this is why i am asking.

Hope i provided enough information for you fellows to help me out.

 

I have the zex 59300 cam for my turbo y8 and it seems to get the job done. Its a z6 cam too . I would recommend upgraded valvesprings though. Apparantely you really don't need the upgraded retainers for it.

i second him
i also have the COMP CAM 59300 and it loves boost

as well they recomend upgraded vlave train, but its not really nesesary if u stay under the stock redline

 

Has anybody dyno'd a Y8 with this cam? I'm curious to see where it produces power and how far it can extend the powerband.

 

i had it on my d16z6 at 8 psi. and it made 188whp with shitty tunning on the hack

 

that was the saab 50 trim t3 too

 

I've just bought Crespo H3 cams and going to install them soon on a ported D16A9 head. We'll see but they look good!
When you install new cams you absolutely need to install new - what's the word? rockers? sorry, I'm from Italy - those things that come in contact with the cam, as otherwise the already worn rockers will damage the cam lobes with uneven wear.

About the valvetrain, as far as I know you need new springs only when running high lift cams at high rpms.
Ask the maker of the cams you're gonna buy about this; of course if you install new springs that'll be an added benefit. Duration doesn't come into the picture at all however.
I am in doubt myself whether buying new springs or not (running a very tight budget...), I can go either way with these cams.

 

you don't have the money for new springs, but want to pay for all new rocker arms? I've never heard of anybody replacing all their rocker arms when putting in a new cam. Has anybody dynoed the zex cam vs. stock cam while keeping the stock redline? I'd be interested in seeing if it makes much power before the stock redline.

 

i do
but the engine configuration was very different

the engines were not the same displacement, or had the same parts
the differences where no P&P from previous engine,the new valves, the new one was bored 40 over, and compression was lowered half a point, and a PM6 vs a PG7 and the after one was without the DC sports headers since i sold them to afford turbo parts

before was 103 wtq and 119 whp
after was 107wtq and 121 whp

 

yea i'd be interested in seeing a before and after dyno with the cam in a turbo setup keeping the stock redline. I switched back to my stock cam now and i didn't really feel much of a power loss. I'm wondering if maybe i just needed to adjust the zex cam more.
