No hard decision in it at all. .

And have it spinning off its head on the freeway? No thanks. Maybe a Getrag box with the 4.11's.As I said earlier, if I had to run a 2.6L I would sell the car. It's personal preference, no question about that. My car as it sits in its current tune I can belt up a hill and sit it between 4300 and have no reason to turn it harder than 6 - 6500 rpm. Sure I can go to 8000 RPM but there is absolutely no need. I just don't understand why someone would go "right, I'm going to build an engine" and buy rods, pistons, potentially a new stock crank, pay for machining and assembly, head service, gaskets , blah blah blah and not spend an extra $1000 or 2 and not build a stroker. Apart from an extra compression ratio increase and little bit of head work that you may do at the time it will drive pretty much exactly the same OFF BOOST as a stock engine. Not sure how you could argue it would drive any different. Forged pistons and rods don't make the power, they're a supporting mod. 2.6's can make the power no question about that. However, the GTR is a big, heavy car with no funky valve control, relatively tall ratios in the 32 and 33, lowish compression by today's standards. As a road car with larger turbos they really are a dumb choice. If you're happy with a setup that you have to turn harder to get the same result, that's great, but to build one is crazy. Look at what's Fatz is doing with stockers. That's thrashing the ass off it on the track with a 6262 making over 400 KW. If you go through his build thread he was chasing more midrange punch, that's why he went the single route. That's even in a track car. "Just rev it, go down another gear", rubbish.

Built 2.6 vs 2.8 Same duration cams Same fuel Same dyno and tuner Same turbo's Same ECU Not sure what you'd prefer.... I'll give you a guess which engine is which.. Carry on...

So a forged 2.6L with a stock head with and set of drop in cams with 8.5:1 compression will drive different to a stock 2.6L with a set of drop ins?

Nissan used a 2.6 L engine because of the group A rules at the time. If you look at the R34's they were using 2.8 L engines. As for this "rev" thing, WTF. Look at the length of strokes in some of the Honda engines. They have no issue spinning to the moon. 2.8 engines even the 85 mm stroke of a RB 30 isn't particularly long. All jokes aside, if someone said I had to go back and use a 2.6, id sell the car.

Some would argue the side wall loads with the shorter rod to stroke ratio. Meh, by the time that would really become an issue you would have sold the car or you would have given it a freshen up anyway. Then there is the argument of "revving" which is dribble. There really isn't a downside as such, unless you don't like more low to mid range punch. A 77.7 mm crank should be the smallest you should go. To spend all that money and go to a "2.7 / 75.7 mm" seems a bit of a waste. If you're considering building a 2.6 why not just throw in a good condition stock engine. Look at Fatz. By the time you buy rods, pistons, possibly a new stock crank, paying for machining and assembly only to have an engine that will drive almost identical to what you had. (Save for comp ratio increase or minor stuff like that) Why would one do that? Stroke it! 2.8 or 2.9 and enjoy some much needed midrange twist that they so desperately need.

Some are. After seeing this, I'll be going back through the fuel system with a fine tooth comb. I've never had an issue like this before and the car has been using E85 since 2010.

Make it home in one piece?

After the best bit of two years sitting around after popping the gearbox, the car finally made it back onto the rollers in Friday night. It didn't feel right so the tune was stopped. This is what came out of my filters. The car was parked with 98 in it too. A fair amount of silty junk was found in the baskets of the injectors also.

Thanks Pete. I'll have a look today!

It is retarded about 5 degrees already Micky.

It will hopefully be out on Monday at gate pressure which is 19 ish psi. Run around for a few weeks for the changes. Need to nail this fuel system. It's giving me the shits.

Lol. You're a clown! Go and have lunch!

Lol. Piss off Pete! No half ass shifting with this box though. If you want to shift, pull the bloody thing! Talk about an anti climax!

Had issues. Got it on the dyno, looks like fuel system is blocked up. Ethanol sensor reads e27 regardless of fuel. Will be looked at Monday. Clutch feels great. Super surprising.

My 044 Intank is not loud at all.

Lol. Want one jangles? Cheap cheap

Can't use shockproof in a getrag. It uses ATF fluid.

Better order that OS88, Pete. Want Aaron's number? Decent price

When's pickup, Pete?

They're all the same. Airbox's are not, obviously but the manifolds, "twin turbo pipe" and all the other bits and bobs are.

That's because it is an OS triple .

Seems that way. Seen more OS sets bust than getrag's.

It's been 18 months!
