Best Choice Of Motor?

[James_94]

Hi guys,

I just wanted to pick everyone's brains about a few things, basicly what im planing to do is buy a second hand motor and spend the time im on my p's doing the motor up, internals, turbo etc, so I was wondering what's the best motor to go with to get nice but safe power figures out of, also i was wondering if the motor will fit in any skyline or are they specific to that year range?

Another thing is what is a good gearbox to suit the motor?

Looking foward to hearing your advice and feedback

cheers.

James

So many variables... What will the car be used for, how much power do you want, what car is it going in etc. etc. etc.

[James_94]

Basicly it will it will be a weekend drive may be taken in a few track days etc, power wise i want something that goes hard but still be reliable.

Cheers

Forget the power.

Learn to drive a car first.

Buy a R31 and do your "enthusiast apprenticeship" on it.

They are cheap, fun and it won't matter if you break something, not as much as an import anyway. Nothing worse than dropping $10 000+ on your first car and being too scared to mod anything, or modding things and making beginner mistakes costing you $$$$.

You gotta go with a 3.0 bottom end.

F^^%$#@! torque monster.

I picked one up from a VL for $380 at the wreckers

If you''re after more than 300 rwkw, go forged internals.

The 3.0 is quite serious, so think medium sized turbo as a minumum. 3076R or bigger

Go large AR exhaust housing if you go 3076.

I have RB25 head and kept VCT with Tomei Poncams.

540 bhp , soon to go water meth or NOS for 600.

Peak torque at 4500 rpm and peak power at 6000 rpm

For a street car, everyones reaction is FMD ( f**k Me Dead!)

I already own a different car that i will have for on my p's and onwards, this is just a case of having some space down the shed, being interested in cars and wanting to have a project car to slowly build, its not a case of spending $10000+ on first car and im on here doing abit of research to avoid the beginner mistakes.

All im wondering what's a nice motor, gearbox combo to drop into a skyline later down the track?

[R31Nismoid]

stock rb25 with a stock gearbox.

put a 3076 on it, make 280rwkw, be happy and then spend 5k on suspension/brakes.

[James_94]

Is there some problem with me wanting to build a motor in your eyes?

[R31Nismoid]

You simply don't need to.

280rwkw is plenty for most people on the street with occasional weekend and is within the limits of a stock motor and then other things like cooling system, brakes and servicing.

You said yourself - you don't want to spend $10,000 - so unless you do want to spend 10k, then go with what is tried and proven time over to be cost effective & reliable.

[sydking]

From my experiance, set 20k minimum aside before starting anything

[gtsttrk]

RB25det NEO. Pick of the bunch. Unless of course you're wanting to go 26.

[nomnomv8]

There is no way on earth you will build a motor for 10k, well not properly anyways. Agree with nismoid on this one, simple bolt ons to get abit of power out of it and with the left over get yourself a set of coil overs and take it from there.

Going from P plates to 280rwkw in its own should be more than enough to satisfy you anyways

WIN. Whats a 26 got over the neo to justify the substantial extra cost?

[nomnomv8]

WIN. Whats a 26 got over the neo to justify the substantial extra cost?

The fact that he can run a very reliable and safe 330rwkw+ all day every day with nothing but injectors, fuel pump, exhaust, computer and a set of turbos or a single on it where as the Neo would be a ticking time bomb at those power levels on an unopened motor..

VCT, oh wait no it doesnt, all its got is 100cc.

Me, for a RWD Skyline I would be building up a RB25 NEO head on a RB30, would end up cheaper than a 26 build but more torque at a lower RPM, and you dont need to rev it hard to make power, just change gear and your in the fat spot in the torque curve. You cannot beat cubic inches.

But as stated before, what car will it be going in( THIS IS A BIG FACTOR)as this is a nissan based site, Skyline RWD oR 4WD/S15/Datsun 120Y/300zx (engine out) legal/engineered, trackdays/superspints/drags do you want to run in a specific class, is getting 300klm a tank a issue, and as for getting some driving skills do some driver training, you can still go out on a low boost setting till you get use to the power.

Remember you may need different mounts/gearbox/brakes/diff/fuel system ect ect ect

I say make up a real time budget first and a time line for the build, THEN, triple the budget and timeline and you should get close to the final tally.

Me, I would like to build a 62 EK Holden with my current 25/30 motor, BUT, to do this I have estimated a total build cost of $60,000 which would no doubtably blow out to at least $100,000 or more.

Or just buy something you like already built and save thousands.

FWIW, Ive spent around $50,000 on a car that in the current market would sell for $12,000, dont get me wrong, the car is a animal and the most fun you can have with your pants on, but when I started the build I just wanted something for street use with the occassional track day, LOL....

Have fun deciding

MOOOORRREEEEEEEEEEEE POWWWAAAAARRRRRSSSSSSSSSSS.

I say make up a budget first, work out time line for build, THEN, double the budget and timeline and you should get close to the final tally.

This!

Are you retarded?

[AngryRB]

I think even a good 200kw or 250kw on a stock is more than enough for a p plater to get there kicks, you could kill yourself on the streets with that....

Why would you build a motor?? Have some fun with bolt ons and learn what it can do, a highflow turbo bolted on is enough to lose it sideways with stock setup..

[TiTAN]

stick the money in the bank as you go instead and let it earn interest. IF you still want to do up a turbo car after you get off your P's then you have the money there to do it or you can put that money to use some other way if your mind has changed.

someone once gave me some good advice, buy the cheapest car your ego will let you. the more expensive it is the worse it is if you wreck it or parts break.
