4.6 now you are talking. You can take another 800rpm out of that. For more low down grunt.

It will knock of some rpms of spool at the bottom but it will also I'm sure knock off some rpms of the rev limit as the rod angles with a 4.6 must be far from ideal !

I'd rather a high revving 3.8 barnstormer, my vr38 on e100 revs to 8500 rpm
I'd like to know the safe rpm limit of the Manley 4.6 stroker kit ........

the first limiting factor here are the small .180" Wall piston pins which are not even good for 1000hp. the pistons and rods themselfes will take a lot more than 1200hp.
Got the same pistons with only 0.18" Wall piston pins. My tuner told me 1.100 hp wouldn`t be a problem.

I am pretty sure your limiting factor are the stock camshafts.

Jamie P runs stock heads and cams (uprated springs) and I'm sure made 1150 whp on ethanol.

That's on a switzer r1000 turbo which I think is a modified GT30

Gt3081s I think he said, 980 whp at 2 bar on pump fuel, and on a dynojet looks like full boost about 4500 rpm, mine only makes an extra 100 hp on pump fuel at 2 bar and I've got worked heads and 272 cams and I'm 1000 rpm later spool at 5500 rpm for max boost !
Jamie's setup is working really well incredible for gt30s minimum lag and upto 1350 hp crank power :cool:
And remember we are talking wheel figures here not the guestimated flywheel figures

well good luck!

should have went with the Manley Extreme Duty Pistons which include the 9310 alloy .210" wall pin:

PISTON WRIST PINS AND PIN OFFSET
Manley Nissan GT-R pistons are designed with offset wrist pins to reduce connecting rod angularity. Please note the arrow on the top of each piston. This arrow MUST point to the front of the block. The Standard Series pistons come with Premium Chrome Moly 0.180" wall (625 Series) or 0.210" wall (626, 627, 631, 633, 634, and 635 Series) pins suitable for up to 800WHP. The Extreme Duty Series come with 9310 alloy 0.210" wall pins suitable for 800-1600 HP. Engines up to 2000 HP it is recommended to install our Turbo Tuff/DLC 0.250" wall wrist pins P/N 42745. Engines exceding 2000 HP it is highly recommended to install our Turbo Tuff/DLC .300" wall wrist pins P/N 42746.

Yeah it must be low revving, we asked callies and ets about my max rpm and he said 9000 would be fine ocasionally as it rapidly wears the valve train.

These are used by ETS for 3500 the one on the right of pic
Those are nice n thick.

I got CP pistons with HD wrist pins myself.

What I meant with my message was that it is hard to see that the engine is assembled so that the pins can take less power than the connecting rods itself. I think it’s the wrong place to save costs.

Or let’s say if 800whp really is enough, there may be cheaper rods and pistons on the market for that power level.

The reason I went for the 4.6 was more low down grunt. The toque comes in much earlier than a 3.8. There is no need to rev the nuts out of it. 7600rpm is fine for me. And you only need 1.7 bar to make 1100bhp with ease.
