I've been researching the past several months on what turbo to upgrade to and have quite a bit a data on 18K, 7670 (top choice but more expensive than I wanted),5858, but can't find much data for 7163 support mods. I know stock airbox, exhaust, etc. but not sure on fueling. I currently have ETS intake, Depo Racing FMIC, UICP, HFC, Magnaflow cat back, Synapse DV, GS 3 port tuned by CBRD with stock SST, no cooling/heating upgrades. If I were to purchase a 7163 kit, do I need bigger injectors, fuel pump, anything else? We have no E85 available here so will be on 93 only. I'd rather do it once and be done so would rather setup everything for maximum potential rather than upgrading more parts in the future. Due to back injury and numbness down left leg, the sell it and get a GSR is not an option. I know I'll eventually need a clutch pack upgrade and have been lucky so far. I have 52000 miles and never had a transmission issue yet. I was set on the 18K until I realized the cost for install support mods and tune doesn't equate for cost vs gains. I'm unable to install kit again due to my back. Any suggestions would be appreciated, I'm looking for quick spooling and reliability. Any other kits to look at?

Fueling if you plan to only run gas is pretty easy. You need a walbro 255 with install kit (I ran the kozmic motorsports) and a set of ID1050X injectors.

Then when you start making more power and are ready for clutches I would hit up kozmic motorsports. An HP10R clutch setup will drive like stock and handle the power that 7163 will put out.

Thanks,

If you use the Asnu 330 pump, it's drop in (no install kit or modding the stock pump hanger) and flows more than a walbro 255, so it'll support a bit more for future upgrades.

I would go with an 18k over a 7163. You're getting 100% OEM Mitsubishi reliability from that turbo. You already have an intake, so you'll be bale to use that by just getting a straight 3" coupler. There is no reason to change the exhaust manifold. So the turbo and a down pipe will run you <$2500. And it can make more power/torque than your stock SST can handle, especially on E85. And you won't have to worry about the turbine falling off like an EFR.

If you do this upgrade, the SST will overheat very quickly for certain on any track (other than 1/4 mile). Actually the SST overheats without ANY power upgrade to be honest; once you take it off the street. More power = more heat though, so keep that in mind. As mentioned above; there is a LOT to be said about the 18k. It can take you to the limit of your block and clutch pack. Going for MORE power beyond an 18k means an exponential jump in $$$. I personally avoid welded up tube manifolds. They look pretty, but will eventually crack on one of the welds at SOME point.

Thanks for the suggestions, so technically I would need 18k, downpipe, Asnu 330 pump, no injectors? I just hope I'm not wishing I went bigger, I would love to be able to make power throughout the entire powerband instead and a hair dryer after 6k rpms or so. This afternoon I'll probably pop off exhaust manifold cover to see if I have any noticeable cracks in mine, if so I'll get MAP cast manifold. I just wish we had E-85, that would be enough to have fun with stock turbo.

Jaraxle

Without E85 you should get ID 1000cc injectors. With E85 you would need the ID 1300cc injectors. The 18k makes power through the entire powerband. ANY turbo is a balance between too small and too big. The 18k sits right where you want, which might have something to do that it was DESIGNED for the Evo X as an upgrade to take you to the limit of just about everything (from the factory). There is a reason the turbo does so well. 18k, fuel pump, injectors, tune... And think about SST cooling if your going to take her to a track where she belongs.

Jaraxle

Oh and I assume the magnaflow catback was modified to get rid of the restriction at the cat connection? If not fix that. You need to free up the exhaust for the larger turbo. Also, don't forget your downpipe. AMS widemouth is built with quality and durability. I highly recommend that downpipe, it is an engineered cast stainless beauty.

AMS, ETS, and STM all make nice down pipes that are worth looking into.

Even if your manifold is cracked, I'd just find a not cracked stock one for $100. The MAP manifold makes turbo spool slower.

I appreciate the information, now I don't know what to lean towards. I'm looking at bare minimum 18K, AMS widemouth, ID1050, Ansu 330 at a cost of $2900.00. I'll have to pay for install as well as tune, so right around $4400.00. This translate for me to go from around 330ish whp to 400ish, $4400.00 for an extra 70whp on 93. I might have to slow my roll and rethink all this, this cost vs rewards isn't working for me. Jaraxle, the exhaust wasn't modified so I'll look into this as well. I do have a plastic valve cover so maybe I'll just stick with getting aluminum valve cover, fixing exhaust restriction and see what happens next year. I thought I had this figured out but after seeing everything reality set in and it's going to cost quite a bit more than I anticipated. I'm really hoping my surgery goes well the 18th, if so maybe early next year I can be able to install everything on my own which I prefer. If they fix my leg, I think it's time to say goodbye to the MR and get back in the 5 speed game. Thanks again for all the info!

You'll make more than a 70whp gain on 93. It'll be more 100-120 most likely.

Consider that for a 7163 kit, you'll spend even more and see similar gains.

Also, the gains with the 18k aren't just a number. The car will pull ALL THE WAY to 8000rpm instead of falling on it face somewhere between 6500 and 7000. Don't focus so much on the peak number. It makes the car a lot more fun to drive.

but 18K will be a bit more laggy and have later spool... I built a car with 18K and that one runs stock engine, 1000 cc inectors (on 93), larger IC and uprated clutches and trans cooler, 3 inch exhaust as well as tubular exhaust manifold (due to Oe one cracking)... nice turbo but I would go for a ball bearing version of it..

Decisions, decisions. I do hate that the stock turbo runs out of breath so soon so that'll be nice to actually have a powerband. I also think a little slower spool will help keep my SST in check. I don't know what to do now, I'm starting to look at the Audi S6/BMW 240ix and call it a day. This morning it was cooler outside around 58 degrees and went wot, it was "cute". My old IX SE made 542/420 and fully spooled by 4K rpms so that isn't helping me enjoy what I currently have. I think I'll just postpone my search until after my surgery, I don't think this is going to be enough to make me happy and might have to buy a GSR if I can drive one.

Its barely noticeable. 37-3800 instead of like 34-3500 for the stock turbo. Car should never be below 4000 if you're trying to drive spiritedly anywaysz

kikiturbo

I agree, but when you DD it you do notice that lag.. as I said, I'd love to try the BB version..c

LetsGetThisDone

There is no BB version. It's an MHI turbo and they only released a JB version. No turbo spools the same as stock, so to say the 18k is "laggy" is pretty much pointless since even a 7163 will have similar spool up characteristics. If you want the least lag possible, the 18k or 7163 are where its at, and they'll even have similar power potential.

If you can't handle any more lag, then you should probably stick with the stock turbo and deal with the horsepower short comings.
