Well it all depends on whether you actually need it or not.

What are your plans ?

Why do you want to modify the existing piston ? There are numerous cars making 700- 800bhp on the off the self piston ?

[[200]]

Well I want the bottom end to be bullet proof. Customising pistons through CP's is only an extra $200 from experience, so why wouldn't I go for that and have the peice of mind knowing that I push the motor to its limits.

[Spoolup]

Sure - all Im saying is that unless you have some serious plans and a huge budget it might just be a waste of time.

also there's no off the shelf dry sump sump currently, however i heard hi octane were in the process of making them.

No engine is "bullet proof"; otherwise the professional race cars, with their unlimited budgets, will make them

The only way round this is to make a 1000hp engine and only use 400hp

Hey guys im finding that when fitting the RB25 oil / water cooler onto the RB30 block that the filter fitting is quite loose over the RB30 filter thread. Any tips for removing the RB30 filter thread and fitting the RB25 o-ring setup for the oil / water cooler.

I'd prefer to keep it than just run it like the VL/R31 skyline setups.

if you do a search in this thread for my name you should find some info on it. i remember going through this dilema and i posted up some info, but i forget now and i ditched the std cooler arrangement

[Bliksem]

thanks shanef! been searching before posting a bit actually, but the answers seemed to point back at using the std RB30 setup which it looks like you've done. I know the RB25 setup can be done tho!

hey guys i just ran into a problem as i was filling my car up with water i found a leak out the water pump. the pump i am usin is a n1 pump and it is leaking out the m6 bolt hole. i have tried using some lockseal but i cannot stop it leaking. it is not under presure so i wanted to know how i can stop tis leaking

thanks

[shanef]

is it the elongated hole? i remember seeing this issue come up before, just pull it off and weld er up

[r33_racer]

or.....you can make a washer thats oval shaped and put abit of silicon on that so it seals around the oval hole. Works just fine.

[nemini90]

that suck almost finisde now i have to puul it apart thanks for the help

[r33_racer]

you dont need to pull it all apart, just make up the washer and then remove that one m6 bolt, silicon it up and bolt it back on.

i just found out a couple of my valve guides in my head are split. Nothing major it happens sometimes thats why they make bronze sleeves for the valve guides. How crap is this Hi Octane are the only company i can find who sell them for rb25 head and they want $700 for them. ive got no choice but to pay it. Ahh so much money

Anyone using cooling pro intercooler from Just Jap? looking at the GTR style tube n fin, just wanted to know if the internals are any good or just a bit of shit? Anyone got one, or pics of inside one? Cheers!

[Spoolup]

Contact JHH performance ( they are in Bris ) - Im sure they can replace them for considerably less.

Cheers

umn so how do i get a compression ratio of 9 instead of 8.3...... i'm sure it's in there but i stopped reading at page 23... i read that using the N/A head will give me compression of 9? how is that so? the n/a head gasket?????

much appreciated.

i'v got an rb30 with only 105,000k's and intend to drop a 25 straight on. looking for about 500hp. if it blows up il put another bottom on!
