Are you serious? I think you need to calm down for just a second. The spelling is insolent not insolant.

I hate it when i share info from my years with working on motor cars and some shit head come in today and picks a post fight with in his first 3 posts... at the age of 13.... Ive had it with know all's.... The topic was for help and suggestions... If you dont agree then dont say so. Just post what you would do not disagree with what some one else would do...

About 2 years ago i purchased an r32 GTR front cut. Over the next 3 months I implanted it into a VB commodore (cheap car to piss off the common dore hoons) This car set me back 6k for the half cut (sold the trany/intercooler & front axel for 2.5k) Then spent this money on pfc/fuel pump/dyno time/jun cams and it achieved 312rwkw and the car is almost indestructable. I used the brakes from a later commodore as gtr brakes were not compatible with out extensicve mods.

Total project cost inc car 8g's tuned and sold it for 15g's

So i guess im just a beginner...

hmmm dude if u read my post carefully i asked "what mods can u get for 2k to achieve 300kw out of a rb26" i end up getting ur flamage...SORRY O son of rajab for my CARELESS ACTIONS

[netrati]

allblitz, In your photo album it says your car already has a power fc, q45 maf, and boost controller. Is this your old car or something?

[Col-GTSX]

As for the rb25det motor you already have!!!!

It depends on the damage caused from the first blow out. But pistons/rods/bearings and of course injectors are must's. Cams/pfc/fuel pump & tuning are all needed to continue the power for a decent amount of time...

Stage 1

Pistons $1000

Rods $500 (use shocked rb25 ones)

bearings $240 (use standard new bearings)

Injectors 550cc $1000 (HKS/Nismo/Sard what ever brand)

Stage 2

Cams $600 (jun/hks... used would be fine also)

PFC $1000

Fuel pump $280 (bosch 040)

Tuning $???? anywhere up to 1 grand

Thats what i did....

Cheers Colin

stock fuel rail?

[Col-GTSX]

well fabricate a fuel rail... cost me nothing to make mine apart from a few connections about $40.... holds 800ml of fuel in it....

[netrati]

Maybe you guys should start PMing each other instead of adding useless comments to a thread. Kinda like what I'm doing now! :-)

[Col-GTSX]

Your always gonna need a gasket here and a meat pie there so its always a good idea to have a spare $300 for extra's....

Like new oil and coolant... you know just price out the major bits and leave a spare few dollars to get the little bits....

[|\| i s m o]

ah iam "sooo sorry" anyway back on topic....u might wanna have a larger cooler like say..600x300x140... "if u wanna go rb26" like col says than trust T517Z would be a good set up for 350-400kw etc.....take the jms r33 gtr for example it has alot of work done to it and it runs near 400kw....so i dont think 6k is enough, jus my 2 cents...dnt want any1 to go crazy flaming

A 23 year old arguing with a 13 year old self certified engine building specialist, how entertaining.

Husnu, can you confirm exactly what modifications you currently have? If you are going to build your engine, do it right the first time.

im in the middle of getting my rb25 rebuilt, costing me $7500 which includes labour , parts plus tomei pon cams step ones. engine out engine in plus running in on the dyno. wont go into long list of parts but using wiseco forged pistons and fully prepped gtr rods. i think the engine should be strong enough for up to 350rwkws but will only be pushing 280 to 300 rwkws inthe future . hope this helps you.

Always good to hear from someone who has either done the build or is in the middle of doing so when looking for factual info

Forged pistons and GTR rods seem to be a popular combination

[B33st]

Am nearly done on a build myself looking for similar output

Greddy Plenum $1100

Q45 throttle body $250

Q45 AFM $250

Hybrid 600*300*76 intercooler $300

What turbos was this thing running for that sort of power? You would be the first person i have read of making that sort of power using std turbos like suggested by"bought a front cut"

Also why would you need an aftermarket fuel rail, there are plenty of bolt in injector upgrades.

It sounds liek you are not going to be able to do a lot of this yourself, so id be listening to the ppl you plan on using for the rebuild. But the nuts and bolts of what id be using is std crank, RB26 rods, and CP/Arias pistons. Get the foundations right then from there you can always eaasily bolt in cams, injectors etc further down the track.
