I have done some research, but cant seem to find a solid answer, im looking for the best STREETABLE DAILY TURBO for my evo project im starting on, And what the best injectors would be to use, The car will be daily driven, and will occasionally be beat on, Here is the mod list
272 cams
Bigger FMIC and piping kit, not decided on which one yet
walbro 255 fuel pump
Turbo back exhaust with o2 dump
tubular exhaust manifold
ARP headstuds
Headgasket (still undetermined also)
boost controller
Spec stage 2 or 3 clutch
some sort of meth injection

Im looking for the best turbo to run 25 psi of boost efficiently, With the best spool possible, Any opinions are welcome

Also what size injectors would i need to run 25 psi, i dont need anything extra because if it needs more than 25 psi the whole setup will be redone

 

check out thenew turbo that map came out with it.

fp red,3 or 4 inch fmic (ets),leave headgasket alone, get a stock manifold (ported),spec clutchs dont work that great i would do competition or act, and stray away from meth, but if you want meth run 30psi and no more,injectors 880 and up , at 30psi should be around the 520 mark if tuned correctly and motor is in good shape!

 

25 psi is my only goal, the meth would just be for safety, i have no need for 520hp lol its just gonna be a daily and i dont want it to be breaking and me fixing stuff all the time, as far as clutches go, ill never run an act clutch because all the problems i had with them in former DSMs,

 

act is completely different in an evo from dsm. as long as u stray away from the extreme pressure plates that suck. 520 makes an awesome daily lol. 25 psi can be done without meth, by adding meth your increasing the cylinder pressure by a secondary fueling system. Also who is to say meth goes into every cylinder evenly, there literally is no way of knowing

25psi on a stock turbo is fun to drive as well no need to swap it if all you want is 25psi. Nore will you need injector's on stock turbo. whats your power goal that might make things easier.

 

Get the HKS GTII 7460R very good spooling, capable of 450-500whp plus is BB! and for injectors 1000cc for 93 gas or 1250cc for E85 ( the Bluemax are realy good), no need for a tubular exhaust manifold just porte the stock manifold and for the FMIC and the piping AMS is a very nice option
Good luck!

 

FP Red is a great PROVEN turbo. No need to upgrade the headgasket. AMS makes an awesome FMIC and intercooler piping. ID1000's are the only injectors I'd get for your setup.

If you can get 93 octane pump gas in your area then 25 PSI on a stock based turbo is perfectly doable and safe with the proper ECU tune. There is really no need for the Meth injection as a safety device if you will only be running 25 PSI on straight 93 octane. Only do Meth if you will be running 30+ PSI and cannot get Ethanol fuel.

The best tuners on this board are able to safely tune for up to 28-30 PSI on straight 93 octane pump gas given the right turbo upgrade and the proper mods.

The CBRD BBK turbo is extremely pump gas friendly. Also look at the FP RED and the FP HTA Green, as well as the HKS 7460R.

As far as an intercooler upgrade, you can't go wrong with anything that uses the Garrett 3.8" core, such as: The CBRD FMIC, the Buschur Racing "Race" IC, or the ETS FMIC with the Garrett core, among others.

No need for Meth at only 25 PSI.

 

Id say BBK-Full or FP-Green turbo, 3 or 3.5 in intercooler, licp, and ~1000cc injectors, 272 cams with upgraded springs, walbro, stock manifold (ported or unported), tbe, drop in air filter. That would probably get you around the 400hp mark without little sacrifice in spool from stock. You should check out the newly released MAP turbos too.
So the "beating on" that you speak of, will you be drag racing it, or just driving the hell out of it?

 

Let me know if we can be of assistance!

cheers

The BBK Full has proven itself to be a great street turbo that spools almost as fast as the stock turbo and can make over 400whp on pump gas on CBRD's low reading mustang dyno. Those are the reasons why my car is getting a BBK Full now.

 

The beating on will be occasional highway pulls, maybe a drag strip pass every couple months, And i live at US 129 (AKA the dragon, 318 curves in 11 miles) that i frequent often

Can we work out a deal on the BBK Full turbo and the Evo 8/9 intercooler?



Also if i get 1000cc injectors, what kind of fuel control would be needed to control the injectors? 93 octane is available at about every gas station where im at

 

Bro you are already off to a great start… but being that I have no idea where you intend on finishing other than @25PSI; I am not sure which way to tell you to get there. IMHO you could tune for 25PSI with what you have and upgrading to a BBK, HTA Green, GTII (HKS 7460R), or an FP Red… I don’t have any experience with the MAP turbo, so I don’t know what I don’t know. However, I do know with one of the above listed Turbos, your 272 cams, a Walbro 255, “anything that uses the Garrett 3.8" core, such as: The CBRD FMIC, the Buschur Racing "Race" IC, or the ETS FMIC with the Garrett core” as sparky said, and a ported stock EM you could get to solid HP/TQ’s #’s efficiently and safely + meet your 25PSI goal. You really don’t NEED the METH as 1) you are trying to be safe, and 2) if you aren’t going for big (500+ HP) numbers there is really no point. If you aren’t going to be running anything above 93 octane i.e. E85 you don’t NEED bigger injectors, headstuds, headgasket, or a MBC technically. The clutch upgrade is a personal preference and I happen to have an exedy twin bias. But for the numbers you are going to make @25PSI MAX with a DD that takes an occasional beating there are plenty of clutches that should suffice. Jus my 2c.

 

well personally i wouldnt run meth, too iffy, leaks more chance of a fire, more chance to run lean on high boost which means your in debt fixing your oops haha... I see you have 272 cams, which brand by the way, thatll make a difference in how much power you make. Personally I wouldnt run an 02 dump on a daily driver, sounds cool but its more annoying and imo makes you more of a ricer, just get a nice 02 housing ported and coated will make almost more power while keeping underhood temps somewhat lower.As for ic and piping ets makes a nice kit, im swapping my xs engineering kit for it soon. As far as turbo goes any stock appearing will get you to your goal, Im runnin a 64mm fp red, for 2 years 20+k on engine and stock turbo boostin 26psi peak I made 385 on a dynojet in summer on 91. As far as boost controller, as long as your tuner is competent, I would ditch the stock solenoid, and do a 3port, it will hold boost better then a mbc and is compatible with the stock ecu. As far as injectors unless you have e85 readily available in your area, my idcs arent even past 70% im running pte 880s and a single walbro, so if 25 psi is your goal 880s will work, even with a race gas tune. But for safety margin, go for 1kcc injectors, PTE RC or ID 1000 like TopSpeed suggested.
theres my 0.02 do what you will but dont take the advice with a grain of salt, nothings worse then thinkin you know it all then have to spend some money twice. Ask me how I know that haha...im redoin a few things haha

 

Does anyone have any idea where after i changed my stock 560cc injectors to Sard 800cc my injectors duty % always very high even on light boosting its always in the range of 50~70%?

Any idea? As when im on my stock injectors the injector duty always below 50% most of the time even many times of hard drives.
