4g93T gsr engine rebuild, need advice

[thesyko]

haha... we seriously went out of topic already, from 4G93t to 4G92 Tyrbo edi :p

Anyways, I have just made up my mind on the rebuild plan that I will undertake;
1) Full Balance GSR bottom end - Standard GSR internals (Pistons and Conrod) + ACL Full Race bearings.
2) Replace all engine bolts to newer OEM bolts (Cranks, Head and Flywheel, and others) - No need ARP since this is not a race car, just once in a blue-moon will see the track.
3) Fully ported Head w/3 angle valve job, NA Intake cams, GSR Exhaust cams + Adj Campulleys.
4) Intake manifold also ported and enlarged + bigger TB (GTO or E3)
5) Metal gasket 1.5mm MMC, replace all oil seals and others belts with new units.
6) Do I need kevlar (Power Enterprise Timing belt) or should I just use ORI MMC?

Maybe, an SAFC II to smoothen out the fueling. + BLITZ EBC to adjust the boost.

Judging by the above, do you think I can safely boost till 1.4bar or 1.3bar will be the ceiling limit?
And what is the achievable amount of power (WHP) that I can expect?

good choice. Clutch n flywheel too...

2) Replace all engine bolts to newer OEM bolts (Cranks, Head and Flywheel, and others) - No need ARP since this is not a race car, just once in a blue-moon will see the track.

Yes... U don't need those ARP.

3) Fully ported Head w/3 angle valve job, NA Intake cams, GSR Exhaust cams + Adj Campulleys.

Exhaust cams is a good choice to improve on the response... But anyway... If ur turbo is not giving u any lag problem, there's no nessecity.

4) Intake manifold also ported and enlarged + bigger TB (GTO or E3)

E1-E3 or perdana. Super 90 is also cheap nowadays.

5) Metal gasket 1.5mm MMC, replace all oil seals and others belts with new units.

6) Do I need kevlar (Power Enterprise Timing belt) or should I just use ORI MMC?

no need. Just make sure u change them as schedule.

u need a 450cc injector at least. I'll go over emanage blue due to the features n more set point. But just remember to set the emanage/safc limit to suit ur ecu rev limit. Else x cukup minyak after 8krpm.

haha really OOT dy but heck it is a very good chat there hehe
btw E3 manifold can fit in 4G9x series? plug and play or what? btw what is Super 90?

btw sifu sifu sekalian hehe is garrett AR48 the size of TD04?

E3 manifold cannot fit ler... Cylinder CTC distance not same. 4G6X engine stuff where can fit 4G9X engine..?

SUPER 90 example

 

[contreasjun27]

yeah loh this i also know ah but why is ur previoes reply say that what E1,E3 then perdana intake or TB ? sorry confusing here..
btw do you know anything on AR48? is it the size of GSR td04?

Err... Theskyo said TB. So, he should understand I'm talking about E1-E3 or Perdana V6 TB. Takkan perdana manifold can be used..? V6 ma..?

Ar48 is just a of the turbine/compressor housing. A GT2860RS can have a choice of AR64 or AR86 turbine housing remaining the same turbine fin. So, be specific in turbo selection. U have to specify the turbo model in order to know the size.

Yeah !! GT28RS with A/R 64 damn good !! Can get 350whp !! :proud:

gt28rs = disco potato huhu aiyaa carambaaaaaa

OIT... The SIFU came to pay a visit... Lolx....

Wah... U try before..? :hmmmm::hmmmm:

Another OTAI... Just as an example taiko... To explain about the A/R that doesn't indicate the size of the turbo at all. Kekeke...

guys for example this turbine that i found ppl selling in marketplace

Well, I really don't know from the picture. Maybe you should ask the seller from what car is the turbo originated from..? It'd gives a rough idea what turbo they are...

AR48 housing, Could be from RB20/25. Lame piece of sxxt that will never even hold 14 psi...

haha yeah I know...sigh right now I'm running on TD05-18G so pretty lag ler...the boost coming at 4k RPM sigh, but when the boost come is syok lah haha

Wah... U try before..? :hmmmm::hmmmm:

MY fren got 320whp at 1.1bar :proud:
damn syok !!
But I prefer T28 turbo first
save more 2k++ money.... extra money can go for cam

how much is GT28RS man???
320whp at 1.1 bar is madness hehe

 

[veilsideboyz]

I think is around RM3xxx !! ~
Hehe !! OFcourse madness !!But... He have install those cam , con rod + Standalone and etc.. only can get this kind of power ~~

this ofcoz loh just turbo can achieve so much meh hahaha...what turbo are you using btw?

Put all the GTs aside at the moment... The cheapest and the most effective way for ur 4G93 to squeze out power is TD05 16G. Plug and play. Noticeable lag, but acceptable... Once kicks in at around 3k+, the pressure is sustainable.

Provided u get a real good deal like me, then consider modding the manifold and flanges... I got my T28 from S15 equivalent to GT2560R for less than RM800 from a friend studying in Japan... Unit was tip top condition.

IF u wanna know, TD05 16G is rated for 365-385HP at 1.57bar of induced pressure. MHI turbos

Methanol injection when necessary. If ur ECU is rechipped with 2 program, it's possible to run different mapping by just a toggle switch... It'll give you probably around 270whp with stock internals. cams and TD05. Tested... If change to forgies with high cams... 320whp is also possible without methanol. With methanol..?? Guess urself...

hehe... sounds fun leh...

Sounds tempting.... So you men TD05 16G from a VR4 can push push out about 300++ HP eh? I think there are methods to reduce the LAG rite?

Standard internals boosting at 1.6bar..... whoa.... that's like damn dangerous rite. I managed to get a set of CA18 conrods at a bargain price of 550bucks for 4 pc's and a friend of mine gave me a set of 4AGZE pistons. Wahahaha... so now i'm no more limited by the standard internals :p

Now just got to get to the part of assembling the parts together and balancing the engine internals.

TD0516G is from evolution threeeeeeeeeeeee :)
