Just completed my 20g build car put down..

384whp 340lb tq on waist gate presser for break-in @8psi
522whp 466lb tq @ 15 psi.

Way more room for higher numbers but fuel was becoming an issues with my single MB pump. If I upgrade to twin pumps and bigger injectors I could see in the 700 range.

 

originals or 18g's upgraded to 20's?

 

org 20g kit for the VQ DEs

BTW i will be down in Miami this Aug so look for me..

 

That's why I used:


and I'm really sorry if that's upset you

 

Why not do the proper fuel to support the greater potential the 20G's offer?

Do you plan on doing that? What cams do you run?

Im not dissing you because you arent the only one but I have yet to see a legit 20G setup - fuel, cams, EMS, that has shown this community reason to actually want them over 18G's.

All I ever see is 18G like numbers and "hopes" of 700-800whp later.

 

I have a stage 2 fuel set up.. all I need is to run another pump nothin too hard to put together. No cams. I choose not to run cams because I wasn't sure of what my HP goals where and shop told me that I should be fine with the Headwork I had done and also with the Cosswoth Pleumen. I know now that I was gonna pay for it later but O well let me have some fun break-in times with her before I open her up again for some extreme shyt. I could do cams later but not in any rush now. let's see what I can do without them 1st.

 

for the power levels that basically everyone runs with the greddy's (mid 500s), the 18g are a much better option. Problem is you need to drop a lot more money into the 18g kit up front. You need the 3" downpipes and wastegate relocation kit. Thats very pricey.

At that point, you can get a brand new 20g kit with the bigger IC and updated pipes for the same price. And then its all back to "hopes" of 700-800hp later over better power curves now.

 

The thing wit me is... and the reason why i went with the 20g ova da 18g.. 1) Its brand new kit at the time it came out, 2) I got the kit dam near "at cost" of what you would pay for an 18g.. Cant beat that.

 

Can someone spec the inducer and exducer of the compressor and turbine wheels on the 20g's that they have had upgraded? Not people that bought 20g units from greddy.

 

umm read the 1st post

 

I have read a few posts that mention the need for the wastegate relocation kit witht he 18g kit. Is the reason boost creep? Lowering the turbulence of exhaust gases? what exactly?

Thanks

 

good info brought to you by SEARCHING : https://my350z.com/forum/forced-indu...ions-done.html

 

Edited. Meant to say to the people that have had their turbos upgraded.

 

you have a cjm stage 2 fuel setup with what injectors?

odd that you think are running out of fuel at 540hp when cass put down 100hp more with a single walbro.

so ya, what size injectors and what duty cycle? something's amuck

 

cass is running dual walbro's

lance has a single 255 with DW 600 injector

 

didn't he dyno high before he went dual setup?

i could have swore there was someone here that dynoed around 600hp with a single setup on a large return system.

 

Im sure with some modification and running larger injectors/larger lines it could be possible but its smarter to run a dual pump setup.

 

cass only had 1 pump and meth and hit 630 on the DD. A single walbro and 800cc injectors should get you over 600 on a DJ depending on fuel pressure, timing and obviously AFR

 

ya, maybe i'll just throw an inline 044 on there. I have an inline walbro but i'm not sure how much it would actually help. I guess it couldn't do any harm

 

Good luck!!!!!
