my current engine is mitsubishi 4g93 NA from libero iinm.
im planning to bolt on to this engine. im wondering what parts should i get.
im planning to boost around 0.5-0.6 bar only.
my friend told me to get stock GSR turbine + GSR extractor + vr4 I/C.
any leads on the pricing for that? or is that any cheaper alternative?
thanks in advance.
Well, eventually everyone went for BOT route will think it's cheaper than having a halfcut. I would say YES. But not alot. And you may not be even close to what u gonna get from a halfcut.
about the gaskets. i already using metal gasket. not sure the thickness but thicker than normal because i already plan out to bolt on.
as i said. im not looking for high boost. just a 0.5bar maybe.
about the management, i got SAFCII lying in my store waiting to be installed.
so, does my plan seems OK? i mean the stock gsr's things
Metal gasket. U have to confirm the thickness. U will only be able to reduce 0.5CR when use 1.5mm metal gasket. Still too high for turbocharging 7psi.
Management should be something in your list before U think about ur turbo.
Can TD05 be fit into GSR? Pros and Cons? What are the modifications required and cost?
Yes. Need to bore up the exhaust manifold oulet to match the exhaust inlet of TD05. The exhaust flange also have a different orientation. Need to cur out, turn and weld back.
Pros
More effective high boost.
Support you all the way to 3XXWHP depending on set up
Can rev up to rev cut and still feel the boost, provided u've done other supporting mods.
Cons
More expensive
Modification on the manifold needed
Minimum boost 0.-0.9bar depending on actuator condition
LAGGGGZZZZZ
im using the extra injector setup as i have 2pc of 510cc injector laying around here.
How are you gonna control the injectors..? Are you gonna tap the signals from ur ECU..? Can the SAFCII suppot subinjectors..?
I know emanage can control the sub-injector with an independent Map in the e-manage with injector harness.
bro better save cash and fit in a gsr engine! bot will cost more in the end! cause when u start boosting u always wan more! and na engine not made to stand high boost! gsr engine safer and start from there la for higher boost!
Not necessary. It's because everyone thinks BOT is
MUCH CHEAPER than a GSR halfcut, that's why they eventually failed the engine for not knowing the limit of the set up.
Here is a breakdown cost of a decent BOT 4G93 that is reliable:
TD04L turbo with manifold = RM600-RM700
GSR ECU = RM600-RM700
GSR 390cc Injectors = RM250-RM300
Resistor pack = RM80-RM100 (If DIY, will cost <RM25)
TOYOTA 4AGZE Pistons with rings= RM700
Machinig to be done on conrods to suit 4AGZE pistons = RM250
Customized Clutch plate = RM350
BOV/RBV=RM400-RM700
Head gasket and Oil sump gasket when u remove the pistons = RM180
Modification to be done on Oil sump for oil return = RM80
Misc like T for oil turbo oil inlet, hose clips, hosses, water inlet/outlet and etc = RM50-RM100
Intercooler piping from GSR = RM200-RM250 depending on condition
GSR Cams = RM250
or U wanna keep ur NA cams with cam pulleys to overcome the overlapping problem, JASMA = RM320
It's already RM3990-RM4660
Comparing to buying a halfcut, say 9k. here is what u'll get on top of BOT
-A 4WD GB with suitable ratio for turbo = RM1.4K
-A 9" GSR flywheel + clutch = RM500
-A Block with oil squirt = Dunno what's the price cause hard to get
-Mitsu Dashboard with digital AC panel = RM850
-A more sturdy drive shaft with block bearing mount = RM150
-A head with really big ports that U know U'll never be able to achieve no matter how many times u send ur 4G93NA head for port n polish. Say 3 stage porting on NA head RM1200
So, now... Do the calculation again and reconsider.
Like 93NA said. The Gss is very addictive. Everyone says they want 0.5bars in the beginning.

im not thinking of plonking in GSRT engine. as i just plonk in my 4g93 NA engine last month.
also, im not boosting high. i just love the nature of the turbocharged engine. :)
i got the Fuel pressure regulator and SAFCII. about the injectors. im thinking of using extra injectors as i got these 2 pc for free. but i'll be upgrading to GSR injector if that what i need.
also. currently i got myself GSR i/c (kotak tisu) along with GSR stock i/c piping. what i need left is the turbine itself. and im set right?
i've asked my mech, he can custom my oil feed for my turbine.

1 question. can i use RHF4 turbine from subaru legacy? or is it not reccomended? someone offered me this turbine for a cheap price. or i better stick to stock GSR turbine?
U'll end up spending more on modding the manifold and the exhaust outlet.
