Turbo/Heads

Well, the motors out again, current build is stock trans, TC, and cam, as well as stock heads, block and turbo. Scat crank, forged 8.7:1 pistions, and eagle rods. also, code59

I was thinking of changing me heads out to L-35's while I have it apart, I can prolly find a set locally cheaply, and get them done up for a couple hundred bucks. I'm not sure of the improvments I'll get from teh heads without them being completly worked, but i'd prolly do some rough porting myself, and it would at least be an improvment.

I was also thinking about doing something with my stock turbo, either porting the wastegate, or changing it all together. I've heard of people changing the exhaust side, but not much about it. If I decide to go with another turbo, it would likly be a 20G. I've read that a 10cm exhaust housing sppols well with the stock cam and tc, but am unsure. I also seem to read that I would be forced to ditch my ECM control, and be forced to run with either a manual, or AEM true boost.

I guess my qestions are, is that stuff i said in the ballpark of truth, and how does the 20g do with the stock cam, and how will it compair (it being the turbo, heads) to the setup I have right now?

Re: Turbo/Heads

Alright, I've been doing some more research.

I've read that you may need intake gaskets that differ from stock, but It doen;t come up often. I also see things about rockers, I was planning on running just a stock setup, stock stamped rocker will do it for me, seeing as how I'm using the stock cam. I'm unsure if I can just use the stock equipment from the L-35's, push rods, rockers, ect. i also have read that the spark plugs need to be the ur6's instead of the 5's is this true?

Re: Turbo/Heads

As far as the L35's I used them and used all of the rockers, pushrods etc.... from the them.

I used the stock Victor gaskets on mine for a syty.

Just beaware that the rockers are the non-adjustable type on the L35's also.

Re: Turbo/Heads

so being unadjustable do I just torque and pray that they are set right?

Re: Turbo/Heads

Oh, I have a feeling Flints got a few sets around in its yards...But if not I'll have to travil south.

My real worry is getting my hands on a 20G that isn't garbage, it seems like the china turbo's are everywhere and not worth having. I'm afraid to buy one on ebay because I don;t know what I'm getting, so i guess I gotta wait for someone on this board to have one for sale. To bad you can't control one with the factory setup though, that would be kinda nice.

I thought I read that you couldn't. If you can run the wastegate actuator with the factory solinoid that would be awesome, and take a load off my wallet

I dont see why it wouldn't work. I run the PTE actuator with the factory solenoid/code59.

Re: Turbo/Heads

oh, well, perhaps i was mislead to thinking you couldn;t run it with the factory solinoid because I forget that not everyone tunes with Code59. How well can you control your pte with it? is it anything near was the AEM true boost can do?
