Rebuild Time, Suggestions?

[PHaT MR30]

Ok its been inevitable for the last 8 months, I need a new block!

I am looking at 1 thats located in melbourne just gotta get it crack tested etc

I have access to Nissan Genuine Parts at good prices (friend works there). I also have access to a good engine builder, who is also a family friend so it can be done at good price.

my thoughts are if the block is in good condition give it a light hone and use my current pistons with a new set of rings, rebuild it using std genuine nissan bearings, gaskets etc. not touching the head.

my other idea was if it needs to be bored rebuild it using something like forged pistons, but i am not too keen on the cold startup slap of this type, so maybe something like ACL race pistons or those hyperautetic (spelling?) pistons. O-ringing the head and buying a phat turbo.

Power output i was originally aiming for was 200rwkw and i believe this can be achieved with the std turbo and injectors? but will go for more power once i understand what my limits are.

I have a Microtech MT/LT8 and a GReddy Profec B EBC, current power output is ~174rwkw at 12psi, will be upgrading to a FMIC and Dump/Front pipe before car goes back on the road also.

have about $2/4K to play with

Arias pistons are common in many Vic motors without any problems to date

I have 3 cars with forged pistons and none of them "slap", it is simply a matter of setting the clearances to suite. I suggest a long talk with "the family friend" should kill off that myth.

i have wiseco forgies....no "slap" at all in the mornin

We have used around 40 sets of Arias this year with no problem.

I seen ad for Venolia pistons in a few recent magazines.... anyone used them?

Yes they are good but often dont have oil squirter cutouts.

Do i need Forgies for an engine thats only gonna see round 15psi and probably 300/350rwhp if im lucky?

Spoke to some guys that get their engines built at the particular place, said he swears by ACL Race Series pistons.

On another note one of these guys took me for a spin in his VH Commodore equipt with RB20DET, HKS T300, External Gate, FMIC, EMS and Launch Control, was bloody quick!

Darren (Bl4ck32) and I had our Rb30's rebuilt with Wiesco forged slugs.

There's zero slap of any kind. (Doesn't show up as a knock on the powerfc hand controller)

Its not really a yes or no answer but it comes down to wheather you want a reliable engine or not, an engine thats going to last 5 years or 1 year. I carnt really predict the life of an engine but its upto you if you want forged pistons or not.

In my opinion; If your going to do it once do it properly, saves you pulling out the engine later on in the future.

Go the RB30

With forged pistons you could have a more responsive motor as you could step down a size in a turbo and run more boost (20-24psi) to make the same power as the larger turbo would on say 16-17psi. + you could afford to have a tune that is slightly more aggressive.

You always get used to the power and want to pump just that little more boost in so for an extra $1300 the forgy's are well worth while.

Don't worry about slap etc.. That is a thing of the past. Unless the builder is useless.

hmm ok, ill look into it... the guy building it builds race engines.

what turbo should i look at then? i can get a brand new GT3040 for ~$2000 + external gate, but i feel this may be a bit too big for my requirements?
