Just want to know if it's safe to start and let my engine tick over on my standard p30 ecu just to check timing and for leaks ect?

Specs:
* integra type r head ported polished skimmed tri-angle valve seats
* omnipower high compression flat face valves
* supertech double valve springs and retainers
* skunk2 pro series stage 2 cams and adjustable
* 2.5mm cometic head gasket for correct valve/piston clearance
* 45mm itb's
* inlet manifold ported to suit head exhaust manifold ported to suit head and heat wrapped
* ek9 type r high compression pistons
* arp bolts used throughout
* light weight rods
* knife edge crank shaft
* light weight billet steel flywheel
* RC 310cc injectors
* Baffled sump
* Air con and pas pumps removed

All timing set to standard marks
 
Yeah its fine. Its fine to drive it at light load too. Just don't get flooring it as you will most likely run into detonation and wreck the engine.
 
Also remember to keep the revs upto 2000 rpm at idle for 20mins to run those cams in.
 
i would say "OK" to starting it, but I would not recommend driving it. Sorry Rich777.

EK9 pistions?
 
Its ok Tama, i'll let you off this once :p . Honestly though, you won't ever damage a engine a light throttle/low load unless its running stupidly rich. I drove about 30-40 miles on a high comp setup with a set of JUN3 cams and RC's 310cc on a totally stock ecu.

even with...45mm itb's ???????
to brave for me...
 
O crap lol, i never read that. Still though it wouldnt hurt anything if it was only light load/throttle. The problem will more be the car running like total crap and stalling. I'm not sure even it will run on a stock ecu if he's just using the tps sensor on the throttle bodies.

I'm running standard tps what prob could I encounter with it?
 
start it, if it even starts, just do not drive it until mapped correctly...lol

or go with Rich777 and drive it and see what you get? lol
 
If it was my car i'd start it with my wideband setup on it and keep a close eye on the fueling to make sure its not stupidly rich. If i didnt have a wideband then i'd just pay attention to how it was running and turn it off if something didnt seem right i.e if there was a strong smell of fuel and it was idling crap. You can tell when a cars running to rich.

I'm not saying to drive it Tama. I was just trying to say you wouldnt damage anything a low load before i realised it was a ITB setup.
 
No stock map sensor is more than fine. How is the map sensor hooked up ? vacume box ?

Only want to run it for like 60-90 seconds to let fuel and oil pressure come up to check for leaks any where and to make sure I've got the ignition timing something like and other obvious things like misfires and so on you think it'll be ok for that?

What harm could it cause if it was over fueling?
 
If you can get it to idle on the standard ECU it should be fine. I'd be interested to see if it does though, generally the MAP signals from ITBs are too messy at idle and throw the fuelling and ignition out.

I put 50p on it not running with the throttle closed. :))

Overfuelling can borewash the walls of oil, it can cause piston ring bedding issues with new rings and a fresh hone.
 
rallypvc...very nice build specs. :)) Any pics of the itb?
 
If your not already going to do it then remove the spark plugs, disconnect the distributor and crank it over untill the oil light goes off before you attempt to start it properly.

It will wash the bores out and prevent the ring from seating properly. Not something you want. Just see if it starts and report back.

Think I may just play it safe and just turn it over on the key for a few seconds and leave it at that then?
