Hi all,

I'm a long time 2011 Evo X owner. I've had boltons and a CBRD 7163 turbo kit since 2016. My car started having some smoking issues in the spring of this year and sent it to get diagnosed by Moore Automotive. Long story short, the engine is currently getting rebuilt.

I'm in a bit of a crossroads as I was ideally looking to keep the 7163 as I never had any problems with it but there some soot around the turbine housing and has roughly 20-30k miles on it. It's taking a while to see what the turn around time would be to get it inspected. If I want to keep the setup and try to avoid any issues, I might be better off getting a new supercore which is about $1,600.

With all that said, I'm considering another turbo setup as I'm already spending quite a bit on an engine build and my goals are to be around 500whp/400wtq on pump gas and the 7163 would likely not get me there. One thing I like about the 7163 is it's responsive on the street and hits full boost fairly close to stock - so I'm trying to find something that is super laggy on the street.

Some turbo setups that come to mine are:
1. Keep the EFR 7163 and see what I can get out of it with the built engine and perhaps E85
2. EFR 7670
3. Look at something like a G25-660

Any recommendations? Thanks!

 

I just came across this in my research - https://www.full-race.com/borgwarner...ver-sx-e-style. Apparently you can pare an updated compressor cover with the EFR turbo line up and there's been some surprising gains. Need to see if this is compatible with my setup given that I'm v-band and IWG but this might get me to 500whp without having to go with a totally new kit.

 

I don't think a 7163 is big enough to reach 500 whp on gasoline. If you want to retain quick spool I think your best option is to upgrade to either a twin scroll 7670 or a twin scroll G-series. Garrett just announced their new G-series 2 lineup.

 

Yeah - might chat with the shop who's doing the work about what a 7670 kit would look like. Really wanted to see how much I can push the 7163 and see how close to 500whp I could get. But don't want to be itching for more 6-12 months from now and then need to spend the extra dough on labor/tune/etc.

 

I have this cover on my efr8374 but I'm EWG but the covers on efr use vband so no holes to bolt IWG im pretty sure it bots to the center housing back plate. I would go this route of it doesn't hit your goal sell to me, I'm debating going with efr7163 with sxe cover for autox/hillclimbing setup

 

I'll keep you posted. This build process is taking longer than expected .

 

That is a 60lb turbo you have there (max). I don't see why 500whp isn't possible on 93 octane, and it would be super easy on e85. That turbo is the sweet spot between spool and the crazy power everyone expects these days due to the rise of the mustang (coyote). I would stick with that turbo, and changing the cover is a cheap upgrade (apparently). When I did e85 I kicked myself for not doing it sooner. People forget that 30% more fuel also means 30% more EXHAUST and so spool up happens FASTER on e85! Yes, more power AND faster spool. Change the cover if you want, and go e85... 500whp will be a joke to reach.

 

Sent you a PM.

 

The shop I'm using isn't certain if I'd be able to hit 500whp on pump with the Borg Warner 7163 kit I have. I'm spending quite a bit on an engine build, and I'm torn between keeping what I have and perhaps being disappointed power wise vs. getting a new setup and spending quite a bit more. I'm trying to see if I can sell the 7163 kit and that being used towards a new kit.

I'd ideally like to be around 500whp on pump and maybe 525-550whp on E85. I think that would be a nice sweet spot on the street with the thought I'd be trying to keep the best low/mid range possible so it's not a lag monster.

 

I wouldn't focus on the peak number so much man. Making 480 on pump but having better spool will make for more fun.

That said, based on the it being a 60lb turbo, 500 should be doable. I run a Red on my 9 which is a 61lb turbo stock frame and make 580 on E.

 

Thanks. I'm thinking at the very least I'd like to get a tune on the current setup and see where it's at. If I'm unhappy, I could upgrade from there. However, I was trying to avoid having to pay more to swap the kit out. What sort of numbers are you at on pump?

 

Yea, I would just get a tune and see what you can do with the setup the way it is. As for the swapping the kit part, wrenches are cheap lolol.

I didn't lean on it on pump gas, its tuned on gate pressure; 18psi, no timing, etc. Its literally just tuned to be drivable. I think its like less than 300whp lol.

Also of note, I have a 9 so its a bit different than the X but should be "similar".

 

As a quick update, I'm moving forward with an ETS G30-770 kit. After reviewing dyno graphs with the shop, it looks like a 7163 on a built block (On pump) is only capable of 450-460whp and my goal is 500whp. I figured I'll forego the cost of new fuel setup for E85 and a 7163 core, and use those funds towards the new kit. Perhaps I can recoup some of the costs of the new setup by selling the 7163 kit . I'll provide a dyno graph when I get to that point.

 

Hey guys I bought an Evo 7 2.2 L Nitto stroker with a fp zero turbo.

blew up on second day…..

getting full rebuild.

running a evo 8 block
nitto stroker kit 2.2
fully ported and built head with all the bells and whistles
kelford 280 cams

so got the turbo checked and she’s gone too. So I’m up for a replacement.

was thinking of ordering another fp from America but doesn’t seem worth it (in Australia)

engine will be built to handle 800 comfortably, but I don’t necessarily feel like building a dog box so I am thinking to keep it at 450-500 kw at the wheels on e85

what would be the best turbo for this set up and power?

ive been recommended the turbo smart 6466 with artec exhaust manifold. Or a g35-900.

after doing some research I think maybe these turbos are over kill for 450-500kw.

can I please get some recommendations for turbos that will make this power and be responsive / not being under used.


thankyou !
