Built 2.6L

Built 2.6L

There are a few thread around regarding built engines. Most threads i found are a few years old. Are people making decent power on built 2.6s or is everyone just going 3L now?

i would prefer to stay 2.6, my thought process is build a 2.6 with great parts instead of an average 3L. also the 2.6 is an easier in out job as opposed to 3L.

whats the verdict?

what is everyone doing these days?

I'm in the process of building an RB30/26 at the moment.  If I had my time over again I would have stuck with an RB28/29 stroker.  A WHOLE lot less stuffing around.  My car would still be on the road rather than off it for 4 years if I'd stayed RB26 (as the base engine).  I have zero doubt the 30 is going to be awesome but less headaches and a pretty similar result could be had from a non RB30.  I've thoroughly enjoyed the whole process but you'd only do it with a pretty high base mechanical knowledge or get it done in a workshop (but will cost a bomb).

You will get 50 different responses on this, it's a very subjective (and understandably so) question.  At the end of the day there is no such thing as a crap RB, they're all awesome!

Appreciatethe response. I fully realise my initial post is very basic and there are plenty of variables. Im not even sure what i want yet to be honest. I guess i just wanted to know which way everyone is going with their builds these days. Im not looking to be the fastest and break records or anything just want something thatll handle a bit of boost and abuse.

In a 32 I would always do a stroker as bonnet clearance is an issue and its nice being able to take the engine and know it's going to bolt straight back in with no hassles

I'm building a 2.6 as we speak. Turbos have come such a long way in the last few years. You can get a large (800-900hp capable) single turbo that responds as well as stock
Low mounts if not better. Then there is the availability of e85 fuel. Motive Gtr has made 500kw at the wheels on a stock bottom end. When I handed my car in and said I want 450awkw from 98ron fuel, the owner said "no problem". So the answer is "yes" you can make huge power on a 2.6l motor.

Most RB26s are a few years old!!

They made big power years ago and still can today. My choice would be an RB30/26 but it would be simpler and cheaper to put a single turbo on the 26 and make more power than you really need (or probably want).

Quite possible

(or probably want).

Not at all possible

I'm building a rb28 ATM, and if I had my time again, I prob would have went a 3L, yeah there's more stuffing around. 

But at the end of the day, to build a strong 26, you need a good block, N1 or RRR, or as in my case, a block brace to ensure its strong. 

With a 3L you get a block brace and you can go billet mains, in the end it costs almost the same with the extra machining costs etc. 

 

but in saying all that, are what is big power in your words? 

Are will talking 800-900HP atw, like the engine I'm building. 

Or 600hp atw. 

That's the main thing you need to work out. 

How much power do you want? 

What gearbox are you going to run? 

If it's only 600-650hp atw just throw some rods and Pistons in a 26 block, and I nice new age turbo, and be done with it.

 

if you are after 700-1000 than be prepared to spend 15-20k on a long motor and go the 3L

thanks for your input. pretty much the answer im after. im not looking for a million horsepower, just a tough 26. i have been looking around at bottom end bits but there are so many options. what are people using these days in the way of rods and pistons? is the L19 bolt upgrade necessary? upgraded wrist pins necessary?

 

what questions should i be asking machine shops?

anyone know of a decent shop in sydney?

Ring and have a chat to Mark at MRC in Castle Hill, he is a wealth of knowledge in regards to building and tuning RB26s, with all the right contacts for machining, so you are paying one bill, dealing with one person.  Most importantly he is willing to warrant an engine he is responsible for building from the block up.

Even if you choose to take your build elsewhere, his opinion is worth getting as a reference.  If it helps as an ice-breaker, tell him Daniel with the black R34 GTR referred you.

thanks a lot ill definitely look into it. 

what is the general consensus on removing the engine. are people pulling it out with the box or without?

[sneakey pete]

If no access to hoist box on, but you must have an engine leveller unless you have 3-4 friends to lift it up or down to avoid hitting things. Had a few issues with the engine leaning over but using 3 lifting points could solve that.

[r32-25t]

I leave the gearbox in the car and just pull the engine out the top

[WantGTR]

Precisely what i was thinking, box on.

2 posts quote by me.  They state opposite things yet the 2nd one was phrased as if it was agreeing with the 1st post.  Hence the confusilation.

Didn't read it properly. My mistake.
