7a block

gze slugs

custom rods

t25 or 28 turbo

 

any advice on choice of cams will be great aswel thanks :)

[oh what a nissan feeling!]

Run in should be done under high load, and without using the redline end of you rev range.

 

Eg. A good mountain run using higher gears at lower revs on the hill climbs, try to really labour the engine.

Something interesting on running in engines.

Your supposed to load it up so the rings don't put a mirror finish on your brand new scored bores the grooves from bore honing hold oil on the walls which obviously helps lubricate them if they were smooth the rings would work like a squeegee

 

So like oh what a Nissan feeling said load her up a hill it's what we do with our engines at work

oh kk thanks for all the help and info guys

cheers :)

The problem you are going to face right off the bat is that you have an engine with no tune so it will need to be tuned before you can do anything with it but this also comes with a positive, the dyno tuner will lightly tune the engine to 4000 - 5000rpm and will do most of the run in on the dyno for you, you will then be required to drive it around for approx 1000km to let the engine settle in and then take it back to have it tuned to make power.

 

When I build an engine I generally keep it under 4000rpm, try to labour the engine as much as possible and keep it off boost, a few pound won't hurt but don't go giving it to it.

 

Also to mention, new cams will need to be run in, who is building the engine?

 

As for cam choice, I was going to buy HKS shafts but I have recently been looking at these:

So you are going to try to drive it untuned?

 

JASMA? why not, I have one of their turbo manifolds and the work is very impressive, sure if you have $1000 to spend on cams then get some HKS shafts.

 

Before anyone says 'but JASMA is an exhaust regulation' I am talking about JASMA and not JASMA

After spending that much money I would be just getting it towed and leave it all up to the tuner to do.

This is another site that desribes similar methods to the one above. Running an engine in under load is not a crazy concept.
