Finally ordered my race engineering pistons yesterday for my 3.5 $808 with rings + shipping. They should be here friday or monday and will post pics! 8.5:1 comp. 3.5 !!!!!!

 

Tilley, if you dont mind let me know where you got them and what the specs are. Are they forged, coated, hyperutatic?

Im looking for custom rods and pistons for my engine project.

If I were you, I'd just get custom pistons and run cryotreated VQ35 rods/crank.

 

Do you really think the VQ35 rods can handle more than 500 bhp?

 

Im test fitting the parts this week. I got the stuff arriving either today or tommorow. I just need to know how much custom pistons are going to run and with who. Some say go with SGP, some say Crower, etc...., get forged? hyperutatic, too many options. Then get them coated by swain, but how much of it is overkill/waste of money.

Getting the rods and crank cryoed is not that bad. The crank alone does weigh about 45lbs. The block empty is only 60lbs. Getting the crank cryoed might be overkill, dont "really" see the need of that unless Im missing something on that.

I'm no expert on pistons, but from the ONE Quicksilver thread, I'd go hyperutectic(sp?). However, I don't have a clue how much more that is/isn't. Just make sure you use the Nissan chrome-moly top piston ring if possible.

Swain tech coat them for sure. Worth it just to protect those expensive slugs as much as possible.

It's more of an easy to do when it's out, so why not for the hell of it/peace of mind for the crank since it is probably 500whp capable. Not sure of your WHP goal here.

The cryo is worth it on the rods for sure, but again they're probably good to 500whp.

So, IMO cryo the rods/pistons and Swain tech the pistons at a minimum. You could also, Swain tech the heads/valves, just all depends on what you're planning on doing and how much all that costs. I don't know, so might change my tune when I see a bill, but I'd Swain Tech coat FUKING EVERYTHING so you'll be able to run sick boost/hp without worrying about meltdown.

 

If you swain tech coat the shiet, then you looking at well over 1000-1500 in coatings. This is from that 300zx thread you showed me that SCC I believe built up or did an article on. That to me is excessive for a daily driven car. My goal is to go above 500whp, but still alot of cash to start investing.

I read a SR20 that did EVERYTHING including friction coating the skirts, rods, crank for around $600ish.

Add two more of everything and maybe it will be that much?

I'd do the ST gold coating on the pistons AT LEAST.

 

I'd get your 3rd gear cryo'd and shot peened before you get rods or cryo, coat or shot peen anything on the bottom end.

 

So true....

 

Hey, I gotta jump in here real quick. Do the 5th gen (5 speed) manual trannies have as many 3rd gear problems as 4th gens? Especially with the ACT. If not, it seems like a worthwhile investment if your tranny totally dies.

 

I haven't heard of any 5th gens, however there are WAAAAAY more FI'd 4th gens so that's probably why.

 

I thought the 4th and 5th gen Maximas shared the same transmission. No?

 

They do except there are small differences. Such as the internals like 3rd gear have a different part #. Some say that its a stronger gear. I dont know if thats believable.

Also I got a 4th gen 5spd in my car and there is a small difference. And that is the shift assembly on the tranny itself. Its actually 1/4" more in length and that causes your stick to be off by one notch. Like if its in the N position, its really in the lower 2 4 R position. So I adjusted that by heat bending by short throw.

So Tilley, when can we expect this BEAST to be complete?

What stand-alone engine controller are you using?

 

I have been reading about VQ30DET's in australia. Sorry just searching forever in google. I really don't have the website but they say the VQ30DET can handle 600hp on stock internals. I am sure he can expect more with forged components and proper tuning.

 

probably about a month or so pistons should be here today or monday

 

pistons came yesterday

 

Can we see some pics?

 

 

Perty!!! Where did you get them from?

 

Those look sweet.

Dixit

 

Cams are on there way too!!!!!!!!!!!!!!

 

CP pistons?

 

when is the projected finishing date?

 

Are you going with upgraded valve springs and retainers?

 

CP pistons and I will probably be using my DET valve springs

 

CP's are my lineage. I sent the original core piston to SGP who had CP make them. The SGP rods are also my lineage. I have a set of the CP pistons too, they are very nice. Did you get the ARP main and head hardware kit too?

 

yes I got the arp head studs

 

Coolio, two more built maximas. Can't wait to see track times.

 

Little Google search stuff here...

http://www.google.com/search?hl=en&i...istons&spell=1

These pistons are cast rather than forged, and are better suited for boost conditions due to their tight piston wall clearances (they don't expand/contract like most forged pistons). The SGP pistons "should" be OK from the info I have gathered (and my one thread )

The very first link on that page says you should not use Hypereutectic pistons on boosted applications...

Conflicting info, so who the hell really knows.
