What do you think would be a good upgrade for me to be around 350hp. Should i get the HKS FCD and raise the boost up to 15psi or go with lex maf/550?My goal is to be at 350hp, just enought to kill Stang GT. I currenlty have a 91 turbo 5 speed with intake, 3" elbow, downpipe, Titan hight flow cat, Blitz catback and mbc set at 11psi. I do hit fc when WOT on a cold nite.

lex afm, 550s, and safc2 should get you there if not more

you may want an egt gauge as well

 

[oscar35783]

I'm not to sure of how to use safc2.

I made 347 RWHP, which is around 400 crank HP on the Lex/550/AFC combo. Im on an upgraded CT though, also at 21 psi. Still running SUPER SUPER rich as well. You should easily get to 350 HP, Id stay away from the FCD to be safe.

I didnt either. Its SUPER easy to learn, dont be scared of it. :bigthumb:

 

[oscar35783]

The safc2 does come with a manual right?

 

[Hot Dayam SupRa]

yes it does.... im running hks mega flow intake, 3"cooleeze mega mouth dp, gutted stock cat and a hks carbon-ti catback exhuast with stock turbo boosting 12psi using a mbc. i have a safc2, zt2 wide band, and a walbro 255 fuel pump. and it sure does leave a mustang gt far away from me on the freeway. too bad i dont have a power to keep close to a mustang cobra though

 

[driftedmk3]

yah it does.

 

[oscar35783]

Is the lex afm a direct replacement to the stock one or is there any adjustment involve?

 

[Hot Dayam SupRa]

its a direct replacement of the stock one.

 

[oscar35783]

Sweet, time for more boost! Thanks for all the help guys.

 

[stratoayu]

dont just crank up the boost though.. get some aftermarket gauges to make sure u dont blow up ur motor.. especially if ur going to go with just a lex.. the 550's complement the lex perfectly... my adsive would be wideband, boost gauge, oil pressurel, water temp.. but thats just me

 

[TurBo NiNe T 1]

I'd also consider a MHG, cause your aged stock one on 15 PSI isn't going to last too long.

 

[stratoayu]

eh.. lots of people have made lots of power on the stock headgasket.. one guy is over 500 rwhp.. its more how often u change the coolant and prep when putting a new one in. proper tuning. lots of variables

I have hew OEM hg with new OEM bolts torqued to 70lb.

 

[AGlobalThreat]

Boost will want MHG. Oem is ok for NA but any FI should have a MHG. I suggest an SAFC and tuning properly, because a properly tuned engine is a happy non-hg blowing engine

i also made 347rwhp on lexus/550/safc with an upgraded ct-26, but i only ran 15psi....

Should be fine. Don't listen to the majority of the people who say you HAVE to get a metal hg...A new stocker torqued down right is fine, but just make sure you don't detonate badly(so make sure you tune it with some room)

The safc2 does come with a manual right?

I have S-AFC II, black version, like new with all paperwork, in box, used few months, $230 shipped.
