This is what I currently have ( i purchased in current state) and would like to know what others would recommend to add or change.

05 MR

HKS 272 cams/gears
HKS exhaust manifold
Megan racing o2 housing
stock turbo
Tial 38mm wastegate with dump
turboxs bov (forget which one)
Perrin fuel rail
perrin fmic and pipes
ARP headstuds
Vishnu/testpipe,perrin(i think) downpipe
SMC alcohol injection
apexi safc


tell me what you would change or add

 

I would ditch the safc, replace the bov with an ix dv and get rid of the fuel rail because you dont need it. Whats up with the wastegate? How is that working for you?

 

was going to suggest the same thing! Afc and bov...

 

you may want bigger injectors 650-780ish. u dont need the fuel rail but it wont hurt anything. get tuned on stock ecu

 

Yeah, why exactly do you have a tial wastegate with the stock turbo?

 

Get RID of the...

Tial WG - your on a stock turbo, its total over kill/wasted money.
BOV - VTA BOV dont run correctly on a MAF based car. Replacing it with a IX BOV you have better drive ability and is cheaper and OEM.

AND REALLY REALLY DITCH THE AFC

I have no idea why your running a AFC with your setup, especial with meth injection. that's just begging for you motor to go BOOM.

Also is the HKS manifold tubular?? If so ditch it and get a stock ported.

Then GET

some 680/720/780 injectors

This will make you car drive a lot better and get rid of useless mods.

If you want to make some more power, add..

Kelford 272s w/ spring and retainers

Upgraded turbo - BBK, FP HTA GREEN, FP RED, BBK XL (when it comes out).

Or even a GT35 or up, if you wanna get crazy with the power

 

you need ic and ic piping

 

as stated i bought the car like this.

i dont have any reasoning as to why these things are done.

this is why i am asking you, the people, what should be changed.

whats wrong with this ic/piping?
debating on turbo upgrade...ix or fp i am looking at.
i am sure afc is worthless. idk if its wired to defi guages/heads up so i gotta check wiring.
tial depends on swapping turbo or going oem
bov i can do anytime


heres what i think needs to be done..
decide on turbo
change ic piping
oem bov
ditch afc
tune

 

anyone else chime in?

changes are gonna go down asap!

 

I think this is what i am going to do

ix bov
ix turbo/housing/wastegate
ditch apexi
change ic piping and intake
ditch alcohol injection?


basically i want a smooth street car that of course moves nicely.

 

does it have a clutch? need an upgrade as soon as u make more hp?
hows the hks cams? idles almost like stock?

 

if it doesnt have a cold air intake id get on of those

 

Id look into a better turbo also,if you have all the boltons except uicp,and licp..Id get those look into a red,green,or black and get a tune with you alc injection..It should make around 500..Pleanty for a streetcar..hope this helps.Justin

 

I removed Alcohol Kit...wasnt working anyway. (bad wiring)

Can i just ditch SAFC or will it affect tuning? since this is tuned to run as it is i dont want to comprimise tuning by just disconnecting it.

also by changing wastegate setup will that affect how the car is tuned? I was going to change manifold/turbo/wastegate/o2 housing to a full stock setup. Has MBC that i would like to retain of course.

I also found piggyback system for tuning behind glovebox. is a Vishnu setup so i dont know if stock ecu is burned OR if this is how all the tuning is done and just modifies stock parameters. would disconnecting all of this between piggyback and safc??


any help is appreciated!

 

Vishnu Exede and a SAFC. Oh brother both can be taken out

IIRC the Exede plugs into the stock ECU but the SAFC may be spliced into your exsisting stock wiring if the owner previous did not use a patch harness to wire it to. So take both of those out of the car.

Then I would change the BOV to a stock IX DV.

As far as the Tial EWG it's gonna be set up custom so to go to the stock internal waste gate set up is gonna have you likely buying some parts depending on how the set up was done.

Then get the car tuned using the stock ECU
