Getting High Hp... And Staying There

[phee]

Alright, my engine should be getting dropped back into the car Monday/Tuesday but am concerned about my radiator, oil cooler and oil pump. I am going to have around 400rwhp when dynoed, so are the any recomendations on aftermarket gear or will the standard items be able to handle it?

In case you don't already know, I have a R33 GTST S1 with the following mods:

G-Max Wheels rear: 18x9.5 with 265’s front: 18x8.5

Tein hight and rebound adjustable suspension

Full 3inch custom exhaust with Magic Cat and twin Mufflers

Ball bearing T70 turbo on X-Force highmount manifold

Turbosmart 48mm Pro-Gate wastegate

100mm think Front Mount Inter Cooler

Blitz blow off valve

Sard fuel pressure Regulator

Sard 550cc injectors

Walbro 500 horsepower fuel pump

Motec Enginge Management System (M600)

Exceedy 5 puck clutch

Pod air filter

Oil catch can

Additional thermo fan (2 in total)

Bonnet vents

Isotta Steering wheel

DBA 4000series sloted disks alround with braided lines

Braided fuel-line, blow-by, breather and radiator overflow hoses

New chrome radiator overflow tank

Gates Racing radiator hoses

Viper 790VX Pager car alarm

20thou Arias Pistions

Adjustable cam gears

Full gasket and bearing kit

Cometic head gasket

GTR rods

ARP head studs

Is this enough to keep the car from overheating?

Edit - f**ked up the hp figure.

you wont get 400rwkw with 550cc injectors and you will need to get an oil cooler up there, also good luck getting 400rwkw up there in darwin....

[Adriano]

and goodluck with 400 with the t70, they dont have a very good reputation of being robust

[R31Nismoid]

Bigger injectors, 740's is where your gonna be at now

Walbro - wont be upto the task either. Time for a surgetank, walbro lifter and bosch feeding the rail.

What oil pump did ya stick onto it?

And i would be using a bigger ally radiator... around $660 for them give or take

[sinistaGTR]

maybe just aim for like 300rwkw.....

[phee]

Shit sorry, I meant 300rwkw, I was thinking hp cause I previously had 365rwhp so I am aiming for 400rwhp. Sorry, over tired. Still recovering from last night.

No cams?

[phee]

No cams.

On the to do list.

Got ducting on the intercooler?

What I mean is that air is directed into the 'core' of the intercooler and then ducted through to the core of the radiator.

The idea is to 'seal off' the gaps around the edges of the intercooler so that the air hitting it has no where to go but through the core.Quite a bit of air will happily 'wash' around the intercooler over the end tanks etc. if there are lovely gaps there as they create a relative low pressure zone. It's best if you can direct the air into the core in a sort of a slightly 'angled in' way rather than just sealing it around the end tanks.

The goal is to channel all the air into the core of the intercooler and through the radiator and then perhaps out a back facing bonnet scoop angled towards the radiator. Alternatively grabbing some washers and longer bolts for the bonet hinge you raise the rear of the bonnet so that you have a small gap at the back edge when its closed.

Make sure you do the same thing for mounting an oil cooler and always remember to have a radiator shroud for any fans you have on it, electric or otherwise.

that will help a bit but not a lot.....

and yes phee what you have should be ok for bout 300rwkw, dont be too dissapointed if you dont quite get there due to the heat.

[rev210]

oh forgot..

turbo beanie and thermal tape the dump pipe. If you have the coin then ceramic coat the turbo exhaust housing, dump pipe and x-force manifold and tape it as well. That will get the under bonnet temps down big time.

The pod filter is in a nice cold air induction box too I hope, with a good air feed.

No cams.

On the to do list.

only purchase them if ya run out, stock heads are pretty decent

[rev210]

upgrading the cams in my opinion is a priority. You will increase the power band a great deal, decrease the rpm needed to get boost , decrease intake charge temps due to lower restriction at the valves and reduce the needed boost pressure to make the same power if you decide to limit/cap it at 400 or whatever.

You have some very expensive supporting mods. You don't build motors around this sort of power target without changing them (cams), thats what I call a half assed approach.

[phee]

Half assed, or unable to afford them yet - see it as you will.

Thanks for the advise.

[sinistaGTR]

im not gonna worry bout cams till i can afford them either phee, so yeh im with you on that one

i got 326kw at tyhe rears with 550's (autronic)

[T04GTR]

you spent all your money on the motec lol.

that above list should be fine. the fuel pump will be feeling the presure.

just put anotherone in there to help it. (they can fit) and are cheap enough.

the turbo.. id keep an eye on it. to help it stay alive just do the nessesary cooldown n shit.

keep the boost to 1.1bar max and it will love ya for it

i dont see an oil cooler there? just jap have some coom serk copies for shit money. hows a 36row for 150 bucks grab ya

[Fitzpatrick Speed Works]

PWR radiator, regualar coolant changes header tank

Tape up any hot pipes, ie exhaust, intercooler pipes.

ANd fuel system upgrades....

These are all mentioned but that would be my priority based on your location.

I said PWR to cause you get what you pay for, PWR cores are lifetime warranty and are substantially heavier and higher grade alloy than competitors offerings this will help with heat soak!!!

Cheers

[T04GTR]

very tru

[phee]

I have just finished reading the N1 oil pump thread in General Discussions, and now I bit concerned about getting an N1 pump, however I will need to get something.

Another fuel pump? As in aditional, or get rid of the one I have and buy something with a higher cc? Radiator will need to be upgraded regardless.

Oil cooler, can someone explain this a bit further?

And yeah I spent all the money on the Motec, and it came with a free R33 Skyline
