My Car Will Be Back Soon....

[Italiazr1]

Well my rebuild is on the way.

if anyone remember's i blew my little two litre engine at the phillip island sprints not too long ago

turned out that my head gasket blew and filled the cylinder with water then BANG!!!

too much boost... car was pulling 238.8rwkw with low compression.

so ive finnaly got my mechanic to start the rebuild... ha ha with a few extra goodies...

i chose to re build the 20 because there is too much legal issues with change overs to the 25 or the 30

im happy with the power i had any how..

here's my mods

3 inch turbo back exhause with hi flow cat

gt30 450hp turbo

fmic

greddy boost controller

660cc denso injectors

high mount exhaust manifold

wolf 3d version 5 computer

k and n pod filter

new stuff im getting are as follows:

rebuliding with forged pistons

shot pinned conrods

plenum

cam

hi flowing the head

clutch

oil catch can

just wanted to know everyones opinions

is there anything else i should do while shes open???

what power do you reckon ill make???

[paulr33]

your worried about legalities and youve chosen a highmount with plenum changes - ok

[Italiazr1]

yeah but you try changing an engine back to standard 2.0lt and then just try changing some parts off the 2lt back

what do you think is harder/longer/more expensive/more stressfull if you get epaed??????

[LTHLRB]

cars are all fun.. especially when its involving an engine out job

good stuff and goodluck

i chose to re build the 20 because there is too much legal issues with change overs to the 25 or the 30

Who told you that mate?

There would be less legal issues (as paul has alluded too) because sticking with a high mount is like painting a dogs balls bright orange :sorcerer:

Good luck with it either way

If you want advice on legalities or your concerns, shoot me a PM

I tend to agree with Ash and Paul.

Not too hard to fit an rb25 or rb26 with std ecu, get an engineer's certificate and epa approval, then fit the usual mods.

As previously stated; a high mount is probably the worst option, with regards to legality.

[Italiazr1]

sorry boyz but i checked it all out to make the gts-t comply with the engineersyou need to change heaps of shit may as well go buy the gtr.

high mount i agree is a magnent buthow easy is it to change?

we all went through this before i started

if you guys read the post i wanna know what power you think she will make and if i should do anything else while shes open???

no mumbo jumbo crap about legal shit its been discussed in like 75% of all posts.

[R31Nismoid]

As for power, pretty much the same. I wouldnt expect much over 240-250rwkw. It should sit around there

[Roy]

What cams and what does high flowing the head mean? Cleaned up ports, match porting, modified combustion chambers???

Depends on what pistons you are running, and whether you are usign good rod bolts etc, but i would say the engine on paper should be strong for 19psi and 250rwkws all day at 7,800rpm

[Italiazr1]

yeah i reckon so too but my guess is ill put out around the 280rwkw mark on full boost maybe 22 23 psi only because my last engine was screwed with low compression thats why it wasnt makin power in the first place.

we'll see anyway but id be happy with 260kw all day long at 18 19 psi

the plenum will shorten the intercooler piping hi flowing/porting the head will allow more air flow in. im using the best parts in my engine ive left it to my mechanic on what to get but he said it will put out good power and be real strong. hes also deciding on the cam to bring spool up a little lower

[R31Nismoid]

You'll be really really streching a 450hp GT30 to get 280rwkw i reckon.

See how it goes though, you never know

[Italiazr1]

you reckon??

ive looked up a few other rb20's

with similar mods and same turbo and they are making 280 with no plenum and no porting of the head

i dont really care but id like 280

[Al]

Just leting you know, from experience, head porting will add a little lag to the setup, but mid&top-range are awesome

[Italiazr1]

ok i didnt really know that.. cheers

will shortening the intercooler piping and fitting a plenum bring the spooling down a little though?

or just the cam?

[cln]

depends if the plenum is shit or not.. u dont want a 25 cause of cop trouble but you highmount your turbs? i guarantee you the popo wouldnt be able to tell the difference between my 25 and a 20.. unless pettit busted my nuts.

[Italiazr1]

i didnt want a 25 not because of cop trouble but because it would have cost soo much to get the engineers for it and i dont have all the stock parts of a 25 to change it back once its modded and i would have put my high mount/same turbo ect ect on the 25 anyway

thing is if i got epaed on the 25 with no engineers id be screwed completely

the way i have it now is i have all stock 20 parts if i get done i change it back cost is a little less.

to get an engineers on a 25 you need to do breaks gear box ect basically need to make the 32 up with all 33 parts.. well thats what the engineer told me to get it to pass

too much stuffin around rebuild for the 20 was cheaper anyway and i have more money to spend on performance parts.

[Downforce]

get a GT35 dude.

[Italiazr1]

lol i have enough lag as it is...

One day i will buy the 34 gtr but for now my monster 2.0lt will do

you gotta hear this thing dude it sounds like a drag car when its on boost cause of the screamer pipe.

[Downforce]

haha, yeah love screamers they sound tuff. I'm thinking of opening the return pipe off my gate for Winton

[Italiazr1]

cant wait to get my baby back on the road.

its gonna be a pretty tuff20 actually is that #plate taken?? sounds good

anyway it will turn heads i bet i pull 260 270 rwkw easy

we will see ill take bets if you's want $$$ put money down winner takes all

my bet is 260 @ 18psi

280 @ 22psi

Just a stab
