Running In Rebuilt Motor & Other Ass Questions

[S1R33]

Ok guys, i have posted a few questions in regards to this before but need some more advice, there is a very limited knowledge of this stuff in the NT.

Firstly Car Mods

Rebuilt Motor (In Progress) RB25DET

Arias Forged Pistons

Eagle Rods

Cometic Metal Head Gasket

Tomei 256 Poncams

Tomei Cam Gear

Greddy Inlet Plenum

Garrett GT30R Turbo

Bosch 040 Fuel Pump

Nismo 555cc Injectors

Nismo Adjustable Fuel Reg

Apexi Power FC

Now we are looking for 300+rwkw

The car currently has the stock ECU etc.

(1) Will it be safe to bolt everything in once the motor goes back in, like injectors, fuel pump, power fc etc & run it around on the base map on the power FC to run in the motor for the first 1000km. The reason i ask is i have spoken to two local import mechanics up here, one said bolt on the new turbo & run in the motor on the stock computer, the other said the stock computer will shit itself with the cams.

(2) How strong is the R33 GTS-t running gear, ie gearbox, tailshaft, diff, will it handle 300+rwkw.

(3) I have seen alot of skylines with this power running multiple fuel pumps & surge tanks etc, but i have been told the 040 will be fine, is that correct.

(4) Anyone know if i have overlooked something.

1) get rid of the stock computer straight away, stuff that

2) i run 400rwkw and its fine, gearbox are very strong

3) id tend to lean towards the bosch 044 unit...i myself run 2 044 pumps

with regards to running it it, it should be fine for only 1000km untuned.... you only have to bed the rings in etc but your cold start and running will probably be shyte. Should just run it in on the dyno

Will the Bosch 040 be sufficent for 300 to 320rwkw, i kind of want to do everything at once and never touch the biatch again lol

yeah i know, f**king darwin lol. It will be ready for the wet season, so it will probably be around a pole.

from my experiance this method gives the best result.

100 kays of light duty reving. (traffic but not much ideling)

drop oil. and filter

500 kays of "normal driving" on low boost with shit oil.

drop oil and filter

next 500 kays of normal driving with a resonable oil of the same viscosity as what you want to run. on moderate boost. say 1 bar.

so after 1000 kays its readdy to rev and be given a hard time. dont drop the oil for 2000 kays.

after that its gonna be bedded in nicly. and not use oil or blow smoke or have heaps of blowby (depends what clearances your running)

[T04GTR]

at no time should you limmit revs to a pathetic 4k. if you do that you run the risk of scratching the bores one you rev it up.

what happens is as the rings bed in a very small lip is formed at the top and bottom of where they run.

and as you rev it the rods stretch a tiny amount. efectivly making the pistons travel further up and down.

if its only used to 4k for 1000kms and then give it a bootfull the rings will get dammaged.

so after the first 100 kms slowly bring the revs up to your max revs over a period of around 150kms. once yove eased it in to that you need to just drive it normaly and give it some moderatly loaded revving. like back to second to overtake etc etc.

for a referance our race civic motor we put it together and installed it. started it up,bled the coolant and went straight to the dyno.

after 10 mins it was hitting 9 grand without issue. doesnt use oil,no blowby and doesnt turn the oil black in 1 race lol

oh, driveline is fine.

just run it in on the stock ecu with stock injectors. or get a quick "safe" tune in it before.
