Hi Guys,

I'm finally building up my short block to get the most out of the APS TT kit and would like some input on my intended build as I'm still tossing up over a few decisions.

Heres the Plan:

Non Sleeved VQ35DE Non Rev-up Block
Eagle Rods
Wiseco 8.8:1 pistons
HR Headgaskets
ARP L19 head studs (Would HR head bolts suffice?)
Cosworth Bearings throughout
Revup oil pump
JWT C2 Cams
JWT valve springs
ARP main studs

My main concerns are:
- Should I use HR headgaskets and head bolts or HKS gaskets and L19's?
- Are the Wiseco's a good choice for a street car or shoud I go CP's or Arias? Is the compression ratio the best choice for 550 - 600rwhp with the APS TT kit.
- If I want to make power to 7500rpm do I need the C2's or would the S1's suffice. Reason I ask is I'll be running a Haltech so without a reflash I cant adjust the idle and there isn't anyone in Australia that can reflash them.
- Would I need any head work for 550rwhp (on a DD Dyno)

Sorry for all the questions guys but I want to get this right the first time

Thanks
Matt

 

We can reflash your ECU to bump the idle, if you send it here. I would not let that stop you from swapping to a better cam. I like the C2 over the more mild S1 cam.

As far as your build plan, Arias ED's are nearly idestructible, and used in all of our engines. If you are working on a budget, stock head gasket and main bolts would be OK, but I always prefer using L19 head studs. A lot of what you are asking is personal builder opinion, so those will vary.

 

^^ op i would take that offer from Sharif on the idle flash..depends what year car you have too a little....
the arias ed are nice but so are many of the other pistons(of all prices) as i have yet to see one fully fail... so your choices for engine are fine...
L17s would be ok and if you are not sure with hr gasket then do coswort gasket then.
I am not familiar with the different jwt cams but i like the BC cams stg2 quite a bit with their ti shims & springs, excellent mix of power(mid and top end) and still gives you great idle..id get one comparable form jwt or a BCcams itself.
If i was you i woudl consider upgrading turbos or the extreme or a different kit actually... but you are fine....

 

Thanks guys.. I might have to take Sharif up on that if the idle is really bad.

Might use the L19's with the HR gaskets as a bit of a compromise. Others seem to have had good experiences with them. I don't want to skimp on the build but on the other hand I don't want to spend $$$ that I dont need to.

What do you guys think regarding head porting etc. Much needed for my power goals?
Not interested in upgrading the turbos at this stage. Maybe later when I get bored

 

honestly whats a 300$ headgasket in a 8000$ motor build?

 

Your probably right. So the consensus so far is don't be a tight *** and go HKS HG, L19's and Arias Extreme 9.0:1 pistons. Any coments on head work?

Thanks
Matt

 

you can get to 550 with out headwork

 

HR head gasket has been proven to be good enough for FI. There should be several people using them on their built motors, along with HR head bolts. Which its the way i went. Wiseco 8.8:1, eagle rod, acl bearings (which is the same Cosworth uses), HR head gasket and head bolt and rev up oil pump. For 500-600 I dont think Arias is worth the price, obviously if money aint an issue then go for them. But Wiseco's are in my opinion good enough for that power, theres car here in miami with even more power using them, also head work really isnt needed either for that power. btw this is all my opinion ofcourse, im no pro engine builder, just know few things here n there.


$8k for a build, crap, where you getting that from?

 

standard longblock build with cams from any decent shop

 

I make "approx" 700whp with no headwork and pump gas. You can easily hit 550whp with the APS kit and no headwork other than cams.

 

The idle isn't usually the main issue, its that your car may shut off on occasion if you let off from WOT, It may occasionally die.

I have this combination on my build and is one of the only things that hasn't caused any drama. jkenefic said it was good to use - always trust a man with a corn fed Z.

If you want some mild blending on the valves, call Headgames and ask Dave about the new head work package he is putting together - $2200.

Good Luck with everything, hope it is easier for you than it has been for me.

 

550whp skip headwork.

Basic budget build...but solid

Arias ED Pistons
Eagle Rods
JWT C2 camshafts and spring/shim kit
HR Head Gasket
ARP Main Studs
ARP L19 Headstud 95ft/lbs trq

 

Well, that actualy has to do with the idle. If the idle is too low, and your cams too aggressive, you will get the stall action happening after a WOT application. The higher and more stable idle will solve that.

Our flash will fix it.

 

Hmm how much would that be including labor and everything to get that block done?

 

Sorry to be unclear, I actually meant what you said. I was trying to say that the car at idle is usually not the issue. Thanks for putting that in better terms.

 

If the car comes in running, about $7500 all parts and all labor.

 

Too low of an idle will also make the car have too low of oil pressure. I feel like all the idles on built motors should be bumped up around 250 rpms.

 

Jeremy's friend is a smart cat.

 

7500 for cammed longblock build and install?

hmmm....

 

crap crap!!! See what happens when I do stuff on the fly.

I priced it without the cams, springs, shims.

Basic S1 shortblock installed....essentially...swapping a few aftermarket parts for stock. Stock heads.
