Hey guys I got a vg30et from a 88 300zx. It pulled out in 4 hours. Now here's what I got to work with. The engine block is fine it had a blown head gasket so one of the cylenders in the middle got sized up. The crank looks fine and all the berings on it are in good shape. Also there is nothing wrong with any of the rods. The Only problem it has are the piston sleeves and pistons. Do you think I should Keep the existing rods and crank or should I get different ones. Does anyone know if these factory rods can handle alot of boost? What do you guys suggest to do to make this work in my 91 gxe? Iv looked at the Oil pan of my engine and the turbo engine and they are flip floped. Im going to check and make sure when I put the mounting bolts on that it will fit in and have clearance. Im thinking about a jimmy wolf tech ecu and will get a bigger fuel pump. I will probably use the fuel injectors that are already on the turbo engine assuming they are working properly. Also do you think I should maybee use the engine block of my original vg30e and just add the turbo to that and go from there. I dont know how my crank pulley with three belt slots is going to hook up to the turbo engines crank pulley with only two slots. Does anybody know if this pulley is going to fit on a turbo crank? Or should I just buy a new crank for my max and put the oem rods on that and get new pistons?

 

how much did u get your bust vget for and how much are functional ones.

 

I got it for 140$ and a functional one is running around 750 not including shipping...

 

If your looking for a operating 300zx engine go to zcar.com and look in the classifieds parts and they are selling engines for 500.

 

The whole point is to REBUILD the engine he already has in his possession.

 

look at the names, he (jmrader) is the one who has the engine; he was telling the other guy (kingrye) where to get a VGT

also, good luck with the project
from what I've heard, it's pretty simple and everything just bolts right in

 

BY GEORGE I THINK YOU'VE GOT IT!!

since the Z31 manifolds and crossover bolt right onto the VG motor(with some inginuity(sp?)) in your Maxima thats all you need from the 300zx motor...trying to swap the VG30ET out of the Z into your Max is a waste IMO!!! of course the VGT has super low CR, but hell, 9:1 is perfect for boost. just strip down your Max's motor...have your rods "prepped", get some forged 9:1 pistons, figure in fuel/ignition management sysytems and go from there....screw trying swap in the VGT and relocating and rewiring everything, BAH!!!

 

hey da-max.. i already have everything figured out.. if you ever decide to boost your max again shoot me an email.

 

Cool! hey dude I'll definently try to get on AIM tonight...I'm seriously thinking about getting back into it again come this winter(once the motor is in the CRX!)

 

See the problem is money. The crank in my max engine is chood up at the main pulley and the keyway is stripped so the crank is no good. And the crank in the turbo engine is in great shape. I thought the turbo would already of had forged rods and crank, do you think I should use these rods and crank and put them in my max engine and just buy some new forged pistons? The turbo engine had 120k miles on it, but the rods and crank look fine...

 

if I'm correct the rods and crank in both the turbo VG and N/A VG are the same...both forged and both ready for boost excpet I think the pre-'89 VG crank has a shorter crank shaft snout. just get yourself another VG crank and have it knife edged and shot peened(still not too sure what that is?? ) get some forged pistons and I guess you can say theres your bottom end.

 

Rods are not forged in any vg30. The TT has forged rods. Get those,the TT crank and the TT pisons (also forged..check z32.com or others for those parts. They swap theirs for aftermarket forged stuff and sell the used) and you have a 400-500HP potential. The VG rods and pistons are limited to like 300hp if you want any kind of longevity/durability/reliability. 9:1 is not perfect for bosst unless you are only going for 6 psi. The vgt guys run 10psi without an intercooler and that's about the highest you can go without water injection or fitting an IC. Keep in mind the vgt is 7.8:1..way lower than 9:1. If you have it all apart and want to do it right, get the forged stuff. That way you can upgrade until your pockets are empty and always have room for more HP. Also, what fuel system configuration are you using? Stock maxima injectors (178cc/min) max out real quick..even the vgt (330cc/min) have about a 300hp limit. BUt I like the Simplified Electronics EIC (extra injector control) THis will allow you to run stock vgt EFI (computer and injectors etc) and piggybacks a small ecu and 2 or 4 440cc/min injectors onto the stock system. Great for anyone on a relative budget that still wants big HP. PLus, it's internal MAP sensor is limited to 22psi..plenty of boosts for most applications..that will get you way over 300 if you set it up right. What year is the VGT you have? The older models (84-86?) use a T3, the 86+ use a smaller T25. The T3 will give you better system flexibility in the future. You'll max that T25 pretty quick. Good luck. I have researched this alot and can't wait to give my beater max the royal turbo treatment. I'm going to go all out when I do it..use the vg33 block and heads(pathfinder), TT rotating/reciprocating assembly, port the whole damn thing, T3/T4, and away we go! I was going to go all out and go broke to do it quickly, but I think I'm growing up or something and realize that my money is better spent in other places..for now. Good luck..and trust me on the TT stuff, it will save you the agony of breaking a piston or rod and ending up with what you started, a blown vg!

 

boost

 

*sales pitch
Why prep your rods (shot peen) when you can buy brand new eagle rods capable of supporting 750hp! Yours for only $420!!!.

 

I heard Eagle rods are crapola..to be avoided. Not my opinion, I have no 1st hand knowlege. But you get what you pay for you know. WHy are eagles so cheap compared to other provedn forged rods? I wonder....................

 

Where did you hear this from?

 

Thanks alot for the info male. Im going to go with the TT crank and rods. But should I use the VGT block or my N\A block to put back in my max? I will also go with bigger fuel injectors. I wana get as much horse power outa this ***** as I can and rip the tranny off.
ARRRRrrr. Just kidding. But you can imagine how much fun it would be. I wana be shootin for 300 hp in the future.

 

ummmmmmm, what are you talking about.....how much are the eagles compared to JE's??? I think without pins and rings they cost about the same.

 

huh?
Your thinking pistons
I just want to see him back up his claim with atleast 3 or 4 links.

AFAIK VE30depower and myself are the only ones on this board who actually have the rods and ve30depwr is the only one who has them installed..

 

What happend to him? He put the engine together, said it wasn't running right, then disappeared. Did he get is motor going?

 

He just disappeared. I sent him an email a while back but he hasn't answered.

 

I fear the worst. ie.. spent a wad and no go.

Did you give DanNY(the bargin stealer) a hard time when he bought the fuel pump?

 

No but he was afraid that he was getting a non-maxima f/p kit. I had to brag the money outta his pocket. Hehe.

 

you can smack me now.......

 

hmm... i think j30_vg30et might disagree with you... currently running 17psi on his stock VG 9:1 comp.

 

OK, 1: I said I HEARD the eagles were crap, from Paeco. But of course they are biased, as they want to make me rods for $230 each. They said they are manufactured of "cheap Japanese steel". So just hearsay.
2: 17 psi on 9:1!!!!! Is he running an IC or water injection...Race fuel? That seems an excessive. Has anyone verified this? Just seems crazy, as the vgt can barely touch 12psi with no IC or any other means of cooling, and that's at low compression. Check z31.com and search for posts on max boost levels for a stock (internal) VGT. Just stating what I have heard repeatedly from that site, and there are guys there that know every in and out of the VG motor.

 

Youjust might rip that tranny off!!! That would rule...NOT. But as for blocks, use the one that's in the best condition..they are the same. To get the max power from it, shell out the loot for the jim wolf vg kit..injectors (440 cc I think), ECU, MAF from a mustang cobra and cam set. This will put you in a solid 300-400HP position. OMG..this is my dream, a 500HP max. Imagine running 12's at the track, with 4 doors. People (UH..Pony cars!) Traction will be a problem, but a good problem to have right! Keep in mind, if you get the basic components in place (a bulletproof bottom end, big injectors, upgraded ECU which is necessary to run larger injectors..the pulse width of the signal is different for different size injectors, and the turbo stuff) the potential of this engine is really great. Fully built with ported heads, cams, an IC, and water (some guys even use diluted methanol..sneaky!) 500HP is not out of the question. Just better fill in you engine mounts with the hardest poyurethane you can get. ANd get a stage 4 clutch. You will need it. Also, buy a few spare trannies. After you break one, get another overhauled, LSD installed, and the whole thing cryotreated. I priced all this tranny work..under 2000 form Pro-tech transmissions. Tell them I sent you. They will appreciate the developement of a business circle and may cut us all a deal. Their prices rock. Only 350 for a full rebuild (plus parts) out of car. Not bad. Please keep posting questions or e-mail me, I have researched this turbo stuff extensively and at the least have a ton of references I can share with you. By the way, those 440 cc injectors can be found as OEM replacements on a Mercedes Benz 450SL with the V-8. May find a better price that way. But you still need the ECU upgrade. That is $$$. Keep up the motivation. Since I can't build mine at this time, at least I can help you build yours. Where are you from? I'm in South Jersey.

 

That sounds like a hell of a way to go. I was looking at the JWT ECU and I will deffinately check on those 450sl benz injectors. You said a Master Air Flow sensor from a mustang cobra, and what kind of cams are good? I live in St. Louis.. Hard to find Max parts out here..

 

Those benz injectors won't work in your car they are top feed and a different style. You would need at the minumin 370cc or 550cc injectors. IF you are adventurous get a set of 50lb/hr MSD injectors and make a custom fuel rail. Then you get your ECU reprogrammed for boost and injectors. Stock MAF should be fine, no need for the cobra maf. Cams, your choices are ISKY, JWT, Motorsport auto.

 

Thanks for the heads up on the fuel rail. i think those benz injectors might work with the vgt rail though, it's different than a max's. I'm sure I read something to that effect on z31.com. Pretty sure they are the same ones JWT sells for the VGT guys. If he's got a vgt to start with, then they would work. Could have been for custom rail installs. Our MAF must be different than that of the z31 models, b/c most zcar tuners seem to think the MAF is limited to 300HP. It is nice to get the whole package deal from JWT though. everything works well together so I've heard. I've seen custom fuel rail fabrication..doesn't look too complicated.

 

j30_VG30et WAS running 17psi... last I heard, he'd blown the engine because his fuel pump failed and ran it lean.. then kaboom.

but before that, he was running 17psi full-time on pump gas.
custom built T4. big intercooler. 3" exhaust. all done by him.
AND he was getting over 30mpg.

 

Damn, that's impressive. That's why I love turbos..you can make huge power and still get great mileage..IF you stay out of boost! My sig says it all.

 

Yeah, does anyone know what happened to Ve30de Power? I've tried contacting him but he disappeared. Last I talked to him, he was working out some fuel problems (sounded like he needed bigger injectors). I hope nothing bad happened like a blown engine!

Male, are you sure a VG33 block would work? That's something I casually looked into and considered. Though, I never really did enough research to find out. I was just planning on going with a Vg30et but, that would be even better to have a 3.3L turbo! I think I'm still going the vg30et route.

Does anyone have any good source for getting a JDM vg30et? I've been trying to find an '87+ JDM vg30et (I think it was after '87) because I believe those have 230hp stock. I might be thinking of '88-'89. 230hp would be a great base to start with.

 

u mean my kung-fu death grip?

hey just making sure...it's not everyday u see one of those around..LOL

 

yeah j30_vg30et was running 17psi on the stock vg30e internals... with Garrett GT35/40 and an air2water intercooler. he should be pulling the motor pretty soon.

 

I'm positive you have have no 1st hand knowlege about anything you wrote in this thread.

 

or just pick up this puppy
