I Need Splitfires? Uprated Ignitor? Damper Pulley? And Why...

[GreeceS13]

I build an rb26 for 600whp-440wkw..

My specs

HKS Pistons, Rods, Cams(272-9,32), gears, timing belt

Nismo oil pump with all mods for oil problems (external oil return,tomei oil galley)

Single turbo HKS T04Z 0.81 with divided manifold (XS Power) and with XS Power external 50mm wastegate

All studs ARP, All gaskets TOMEI.

A little ported head..

All bearings ACL

800cc sard injectors stock fuel rail

1 intank walbro and 2 external walbro with surge tank

600x300x100mm fmic intercooler

3" exhaust

I need splitfire coils? What the problem if I don't buy them?

The same questions for uprated ignitor?

And for damper pulley?

[jonn]

I'm just using splitfires (no upgraded ignitor) in my RB28 with 522whp. Maybe just get your std coils checked out and try them. There's nothing to loose really and then if you need the splitfires etc buy them then.

[GreeceS13]

How can I check stocks? I have no idea the condition of the coilpacks as I bought the engine second hand.

Also when we need ignitor and dumper pulley?

If I keep the rev limit 8 or 8500 I don't need dumper pulley?

[jonn]

I've got an ATI one on mine to be safe. Not sure what the std one is good for.

Still using the std ignitor. Have a search for testing the coilpacks. It's been covered before.......somewhere.

run the car on the dyno, if they break down replace them. if they don't then keep them.

[GreeceS13]

Sorry but what do you mean break down?!?

Sorry for my bad english..

break down - ie - not work

[Guilt-Toy]

When your doing a power run, the tuner will know the coil packs are having troubles keeping up by how the engine miss's.

if you run the car up on the dyno and make power with no issues you know they are OK.

I think i remember beer baron saying that on the HKS drag car they still run the stock coil packs, they are better then split fires when they are in good condition.

So take your chances, they might turn out to be all ok.

[GreeceS13]

Thanks for the info :)

if your going to rev it hard its a good idea to get a good harmonic balancer

[GreeceS13]

When you say rev it hard you mean high rev limit or high rev driving?

With the HKS TO4Z .81 I don't think that I will need more than 8500.. or 8000 is enought?

[bnr#@]

Sorry to barge in but related question. When changing to an aftermarket harmonic balancer do you just bolt it on or do you need the whole botom end ballanced with it?

That would be the preferable method.

[drgnball34]

arent those xs power items china stuff? You already got the good gear...might as well fork out the extra for the name brand? I got splitfires and the hks twim amplifer..also running ati balancer

[GreeceS13]

Yes china stuff.. but xs wastegate I read that work fine... and the xs manifold I will improve its strenth with brackets! Again I read for this manifold for rb26 signle that it is good quality and they don't broke! I think that also the 6boost is china stuff same with xspower but as I read many people use it!

[R31Nismoid]

6boost isnt china made you idiot. Its made locally here in AUS.

Have you even researched where its made? And by whom?

Doesnt sound like it at all

The poor man pays twice, i suspect days it will also happen in this case

[shanef]

yeh, kyles 6boost mani is pure china junk...

[N1GTR]

For an RB30 bottom, what do you consider revving hard?

[datsqik]

I would change the balancer on any built rb26 motor as I have seen a lot of factory items flogged out. I believe that this is probably the reason behind a lot of broken oil pumps. I build a lot of sr20's and everyone one of those Ive seen with a broken oil pump has had one of those GFB solid pulleys fitted.

[GreeceS13]

Ok ok I didn't know that 6boost isn't china stuff... and I didn't ever seen the very good shceme of theese manifolds...

Don't hit me!!
