Where do i start with internals

[wheels_24]

Hi guys I have a R32 GTS-T, i am trying to find out what to do next my mods are as follows:

pod

wolf 3D

GT30 ballbearing 650hp

hks fmic

fuel reg

3" exhuast

injectors i think about 500cc not sure

45mm waste gate

h/D clutch excedy

Currently the car is running 16psi and i am yet to do the fuel pump which is getting done soon at the moment i have 210rwkw just wondering after fuel pump what sort of internal work i need to do enable me to turn the boost up and start getting some good figures i want to keep everything that i have. Do i need to open the engine up and say some forged piston and rods? Not sure what needs to be done i have heard that you can just put the RB25 bottom half of the engine to replace the RB20 is that right, and help would be great and what sort of prices am i looking at Thanks

Forget about cracking open the engine if your making 210rwkws. Forged pistons, rods etc wont mean you make more power...

If you want more power id be having a look at why a 650HP turbo is struggling to make 300rwhp. If you serisouly want to make anything near what a 650hp turbo is capable of delivering, then id be starting to look at a bigger RB engine.

But id say you dont need to replace anything to make more power, by the sounds of what you have the thing should be able to happily make 250rwkws at sensible boost levels and std engine internals, something isnt quite right if your making 210rwkws

Something isn't quite right if he's making 210RWKW and 729NM!!!

could it be because i still have the standard fuel pump as i have still got the stock one in will the bigger fuel pump give it a lot more power i was told about 25 more rwkw would that be around the mark

[netrati]

A bigger fuel pump will not give it anymore power at the current boost level, unless your car is leaning out which would be really bad. Do you have your dyno charts?

[wheels_24]

at home i have it but i dont have a scanner

[Dee 33]

Something is amiss with this vehicle...

[R31Nismoid]

i agree.

what specs is thisd "650hp GT30" ???

[wheels_24]

not sure bud the guy that gave it to me just said that it is good for 650 sorry cant help anymore then that

[DRIFTER]

where do you make full boost? does anyone know how much power the standard pump will flow. i have the same set up but i don'tget full boost till 4000,and i havn't tuned it yet.

[wheels_24]

i get full boost at about 4200rpm so it takes a while to kick in

[Bass Junky]

Charts.

not sure bud the guy that gave it to me just said that it is good for 650

:wizard:

Maybe two of them make 650 bhp and he forgot to give you the other one.

[R31Nismoid]

agreed.

If its coming on @ 4200rpm then i dare say it has a .63 rear housing.

Therefore leading me to belive its around 500HP and certainly no more than that

[PHATGTR]

Even if that is the case, it still doesn't explain why he's only making 210@wheels on 1.1 bar???

[wheels_24]

ok well maybe he ment it might make 650 if i high flowed it not sure not really fused i cant use that much anyway with the standard 2L all my mods didn't cost me anything as he got done by the EPA and had to get rid of it all and get standard gear. He had no money and i hit the jack pot getting his turbo, dump pipe,45mm waste gate, fuel reg, catch can, bigger injectors all i had to add was the wolf 3D and give him all my standard gear i jumped from 108rwkw to 210rwkw with only paying $1900 for parts not bad ha

[FATGTS-R]

Got any images of the turbo?

Greetings All.

Could i be possible the turbo is sick? Shaft play? Damaged compressor/turbine??

Also, Arnt GT-30 Turbos rated at around 550HP...?? (Non ball baring core night not help??)

What are the turbo specs?

Cheers,

the turbo isn't sick cause it is only had done 2000km when he gave it to me as it was only 1 month old so not sure i hope it isn't cause he gave me the receipt so it should be the turbo i don't now the spec's on the turbo sorry
