Thanks.

 

I'm curious... What turbo kit are you trying to make 750whp with?

 

Overbuilding in 2011?

Not needed, in fact not recommended, but what do I know...

 

if there is anyone who been to hell n back, maybe 20k+ lost in built "sleeved" motor it would be this guy ^^^^^

 

Greddy 20g's w/custom xtra large intercooler


I've been around long enough to know what Berto's been through, **** he helped me build my last one.

I'm not trying to just throw $ away, that's for sure.

 

outa curiosity how come you need a bigger intercooler? the greddy 20g kit one not sufficient? (dont know a whole lot about their kits)

 

at that power level the heat produced will start to become exponential therefore going with a large intercooler to start with saves time and money.

 

ah gotcha makes sense

 

You're kinda just making yourself look foolish.

 

I skipped a bunch of the banter and saw this.
+1 on darton doing the sleeves if you are persistent with the idea. The 8xxwhp thread that's open right now (meatbag with twin 20g's) has his darton installed sleeves since 2005.
I don't think it's a bad idea at all or overkill. Only reason I didn't do it was cost

Str8 and I have differing opinions about rods, but then again Str8 likes to have 900whp
Just make sure who-ever does the machining and building really know's their ish.
Eagle rods for example have a taper on the conrod/conrod bolts... if they aren't correctly stretched/torqued to compensate for stretch they will eat sh*t and die. A lot of shops don't even know about it. Proof? A local guy was just hand torquing the conrod bolts in, and they got stuck at maybe 5lbs. They had to trash the bolts and machine the holes because the taper got the bolt stuck in there. I'm pretty sure he lost a rod or two.. idk the whole story.

Also were you running wiseco pistons?
If so, the wrist pins that come with the pistons are not good for much more than 500hp. You need to upgrade them. I called wiseco to verify that they wanted 4 thou piston wall clearance, and to ask what the pistons could take maximum. They told me then the originally supplied wrist pins aren't that good, and when you get the 'upgraded' pins you could make 1000hp without 'issue'. It was like 100 bucks for the set, and the pins are made of probably a stronger metal and the wall of the pin is about 2x the thickness. I'm pretty sure Z1's 'custom' wiseco pistons are just the upgraded pins + coatings (the cost somewhat reflects this idea too).

 

....and you are? I had built motor, and will have another, where are you @?

 

Meatbag's setup is pretty much exactly what I'd like with pump gas.

 

I myself wouldnt do sleeves (for a 3rd time) unless you plan on running 750+whp all day long.

20G + fuel system + cams can be deadly as we know from meatbag. Standard 18G's can produce sick numbers too on pump and pump + meth as I have proven.

In your case, Id rather run something in the 600whp range on pump easily and push it to 750-800whp on meth or race gas OCCASIONALLY than go for sleeves full time and take the chance going down that path pushing tons of power you likely cant even use all the time.

 

Yeah, that's more levelheaded I suppose, but I've already been right at that 600 mark, I said to myself that when and if I ever rebuilt I'd go higher. Maybe E85. We have time. I already have 11" wide wheels, I could go much higher in tire and get some custom rear fenders to put the power down, I do plan to use it.

 

Well like everyone said then, if you do choose sleeves have Darton themselves do it.

Dont let any Z or big name shops fool you into telling you they can install them with success, no shops here that Ive seen that didnt use Darton have kept these motors together.

Good luck!

 

Thanks Berto

 

i have heard that sleeved VQs are problem prone as well.. just adding my .02 is all. , sleeves moving, crank walk etc.. losts of fun stuff i hear, i did not chose to use them on my build.

Im a noob tho, but again, just my .02.

call it a plus 1 to Albertos comment... i think the issues i heard of were all attributed to installations that were sub par as compared to Nissans OEM engineering etc.

 

I agree with that statement; pretty much my build in a nutshell. Except with a 7175 single turbo and stock heads. mid 700whp on meth. Maybe down the line when I can afford to pop the motor and have someone else do all the work I will push the whp up and see how long the eagles last. I know about str8's experience but I'm somewhat skeptical.

And to add to what bert said about the shops... i'd go either darton (if you are on the west coast because they are in cali) or Sound Performance. SP is one hell of a shop and has the cars/records/and experience to prove it. And their customer service is super friendly/spot on. In fact, I'd probably go straight to SP, because then you could buy a complete short block rather than take your freshly sleeved block to another machine shop...

 

I'm still in a holding pattern until Saturday. I'll know more about what all needs to be replaced then, and what direction I will be heading.

 

Do you have a build thread? I am also working on a PTE 7175 and 7675 as a production kit..
