260DET

Building a projected 500whp single turbo engine and I was going to use Wiseco pistons and Eagle conrods. But the mechanic is giving grief over those choices, no suggested alternatives as yet but you can bet they will be mega expensive whatever he comes up with.

Also any performance and durability tips would be welcome. The crank will be nitrided and the usual serviceable items replaced, have not decided on cams yet. Turbo is an internal gate 1.06 a/r turbine GT35R, we are thinking an effective power band from 4000 to 7500 rpm. Car will be used for circuit speed events.

and this is a z32? or a z32 engine? if so wouldnt it be wise to stick to the twin turbo config?

At that point I would tell the mechanic to STFU personally. The customer is always right. If he is bitching about reliability have him take a look at all the oter guys running 500+rwhp. They all use that setup.

Good question about the engine. Is it the VG30DETT being converted to a single or something else??


Eric- I saw one guy on another forum run a VG30DET (Single turbo Z32) in his Z31. It looked like there was less clearnance issues on the side of the block with the location of the turbo being, well more "up front".

Its a JDM single turbo import engine, having some knowledge of RB30ET's with GT35R's I'm not concerned about the single turbo thing.

So Eagle rods and Wiseco pistons are a common hi-po combination? There is very little done with the VG engines in AU so......

Pretty much everyone uses the Wiseco pistons when they upgrade. I have seen a few people use the Eagle rods. Dont know much about them though. But in any case, good luck and post pics when done!!

eagle rods are pretty good, i have people that build engines that they wouldnt use wiseco they stated another company that i totally forgot the name of. other wise there is APR for rods. or...i think the company mightve been JE for th pistons. not to sure. i will ask if i see him. or his brother.

What kind of engine exactly are you using? Jsut curious. Is this going in the s130 in your picture? Pretty impressive project.

entropy31

sounds to me like a vg30det. thats my guess.

snwbrderphat540

yeah me to. but with the pick and the title and not saying what he is doing just posting in the Z32 section. its my guess to. enlighten us on your project

260DET

Ah yes, didn't say what it was eh. VG30DET into avatar car, full S14 suspension etc transplant, few other things. Thanks for the tips, these engines are not much thought of in AU.

Wiseco pistons have held up for 1051rwhp in Russel of Z1 Motorsports' car... I use Wisecos in my GT2530 powerplant as well. When I rebuild again, I'll be going with Eagle rods too... they're a quality product.

And for reference, I was watching Horsepower TV (or maybe it was on Trucks...) the other day, and they built a Chrysler 440 big block with Wiseco pistons and Eagle rods...

I'm not so sure I would go with a single turbo at 500 horses.....

It's a low [enough] number that you can get a pair of fairly quick spooling turbo's, going single will only increase your lag. How did you come to the single turbo setup conclusion?

entropy31

the motor he has is a vg30det. this is a factory single turbo motor.

snwbrderphat540

no...wait. is it? i thought the vg30et was single. and then the vg30dett.

snwbrderphat540

well i actually know thats what they are^^^ im asking. there was or wasnt a vg30det. there wasnt right?

entropy31

there was. we never saw it in the states.

that link should help.

snwbrderphat540

interesting. nifty to. hey. i learned soemthign today.

260DET

Seen plenty of RB30ET's with GT35R's that have virtually no lag. For example, mate of mine has just finished a GT35R (but with the smaller .8? turbine) RB30ET instal in his S30. Its spinning the sticky race tyres mid revs in third gear, the turbo is fully spooled up by ~3000rpm. Engine management has to be spot on, thats a big part of it.

260DET

Talking with a SR20DET drag racer today, apparently Wiseco pistons for the SR engine have been cracking through the oil ring groove. Which is I guess why Wiseco have a bit of a bad rep in some circles. No problems with Eagle rods though.

snwbrderphat540

JE. i think thats what my buddy said he was going to use in his build. and he is fairly smart guy. ask aroudn about those. i dont remmber if JE was the piston company he said though for sure.

ZLover4Life

The Wisecos for the VG are fine (at least in the case of the VG30DETT)... can't expect every product from a given company to be perfect - just because they're not great for the SR20 doesn't mean they're not good for other engines.
