hehe.. yup.. but tht one just lag pro drag settles it la... mayb go after cny~

Guys.. i got one question..

If you dont run a wastegate, means when you drive you become a manual boost controller (your right leg)?? Is that right?

exactly! then again, there is no compromise in reliability when it comes to bot'ing a na engine. even more on sohc 4g18p.
just sharing my experience, when i was just into car stuff, a friend of mine bot his 4g18(1st generation waja). boosting at low 0.6 bar,
his piston head crack and there was a leakage on the gasket.
for na engine with bot, reliability over performance comes into consideration. but for factory fitted turbo engine, you could have both

should be more than 4k to be consider as close to proper bot with most expensive one goes to piggyback management chip.
be careful of imitation part. perhaps, steven could elaborate more since he is using bot.
there is one half cut trader in mudah site. under the trader name ayie from puchong but his price are quite steep. perhaps, cheaper if buying in bulk.
any garage in sunway could do the job just fine.
also, pcd114.3 of older evo brake might not fit straight into waja. either re-drill of rotor disc or knuckle change require.
for the dual layer brake servo, only those from evo 6.5 can be consider as plug and play to 4g18p. evo 3 and below will not be a straight job, while evo 4 need
minor modification.
4 pots from nissan rb series is another option.

almost similar but not there. without the wastegate, you need to be very very light on your right foot / lower than 0.6bar boost which in turn kill the fun of having a turbo installed .
as far as i know, wastegate act as a proper boost regulator management. without the wastegate, excessive gas might not be channel out properly to exhaust system. also, no proper regulator for the turbine. this effect the turbo effectiveness(sticky) and engine in the long run.

if you dont have a wastegate you probably ahve an actuator

Hey Guys,

Good thing to share here, hopefully will benefits to all Turbo wanabe.

wat cause ur fren piston head to cracked?

kampoon mention safc, but looks like emanage more things to adjust

some ppl dont even replace their brake servo. they jst keep standard servo.... any benefit of the dual layer one?

is tht the internal wastegate?

List of item i've can think off now... anything else missing?

GSR intercooler (not sure if can fit nicely or not seems tight)
Emanage Blue / SAFC
Garrett AR80 (but as far as i read not all AR80 is the same...) <-- got internal wastegate one ar?
Manifold custom
Plastic OEM blow Valve <-- any other options ar? this thing look like no confident
2" Wai Heng Exhaust <-- 2" enuff?
Boost Meter ala Jasma <-- Any other choice?
390cc gsr injector - (waja std - 210cc) <-- online there is an injector size calc. seems tht 210 not enuff big...

yes, internal wastegate. I jsut sent my car to reseal the turbo and exhaust manifold.. and f***, i never knew i had this much power .
Car went left n right the first time i boosted

wah.. the thing cracked ar?

can redyno again

Talking about advantage and disadvantage or internal vs external wastegate boost control~

once you bot the na 4g18p, it will unoffically become a high compression engine. thus, you might need a stronger coil and cam to hold the piston.
also, make sure to tightened up your top with stronger set of screw. or light right foot to minimize the damage.
else, since you're getting emanage, might as well get the dohc top transplant

that was quite a lot for a bot works. perhaps, your car is already goes thorough a surgery' during bot process
standard 4g18p on bot does not take off like a snake.
btw, were you on stock suspension back then? i've had the same minor problem with my 1jz-gte ride when the transplant completed.
turn out it was caused by the lousy suspension. at least, hks hypermax could handle it better.

Added on January 9, 2011, 7:30 pmyou'll prolly need a 2.5 exhaust, boostmeter autogauge also not bad.

his not driving waja ... his driving espri turbo...

yup i heard abt the stronger screw before... cam no... but coil make sense if u boosting high la.. but if boost low need meh?

Lighter,

Intercooler sure can be fitted but depends of time and effort and the installer must have some arts and patient to perform this.
Emanage Blue or SAFC <--- this is depends on ur budget, of cause the merrier the better lor
Garrett AR80 <- yes....ade internal w/g
OEM blow Valve <--that is the original from MMC, u won hear the shhhhh sound by using that, you can buy the aftermarket HKS SQV2 then you will be shiok (less than RM100 for a new one)
Boost meter <- a lot of choice Jasma, Autoguage, NRG, Shadow, Apexi, GReaddy, HKS, Defi.
Exchaust - 2.25 or 2.5" the best
240cc Mivec injector is enough.

Hope all this will help you....cheers ...!!!

thx

Fake HKS SQV2 duno got any diff or not.. but ori one damn f*** xpensive.. like 600 bucks~ crazy
But will the replica one fail and kill your turbo ar?

exhaust 2.25" sounds good~

Injector size i try this calc... duno if correct or not

http://www.nitrostreet.com/injectors.htm

HP - 150
BSFC - 0.6
Injector - 4
Duty Cycle - 0.8

= 295.31cc

Your mivec 240cc oni~ correct me if im wrong still learning~

why you want to boost so high for stock internal,

If you wanna to boost 0.4, you might not need to replace ur injector.
if you booost 0.5, 240cc is just nice and safe ....
if you want to boost high high..then you need to change fuel pump,
install metal gasket, replace conrod, low compression pistons...bla bla bla...

not wan to boost high la

just i thought the bigger the injector have more safety margin to play with instead of having smaller one~ is it not so? then my mistake

yup...

will get it done together wit my steelmate in the future~
