New to the Game...Info Needed

[RED_DET]

Well with the guidance of some fellow moderators, I recently picked up a 93 Twin Turbo in need of a heart transplant. I have been doing quite a bit of research and have come to a few final decisions.

After hearing the horror stories of JDM engines, I have either decided on rebuilding the engine that is already in place with Wiseco Pistons, Eagle Rods & ARP Head/Main Studs. With that said, I have come across this company on ebay that sells rebuilt short/long blocks....http://www.ebay.com/itm/Nissan-90-93-30 ... 95&vxp=mtr

http://www.jisengine.com/

Anyone heard of or used this company before? If so, please share your experiences...their rating on ebay is phenomenal.

Any other suggestions or input is appreciated....

Here are a few pics so I don't get banned. Probably the dirtiest car I have cleaned in a long time.

[NolimitZ32]

Never dealt with that company before but in general I would rebuild it, I like getting down and dirty though.

[Ace2cool]

Or buy an IPP longblock. But those are pricy.

Rebuild is always the best option for price.

Also, the wheels are on correctly. First new Z on here in like 2 months with the wheels on right.

I cant really tell from the pic, but you have the same interior I do. That suede material, isn't real leather its a fabric suede. This is how you clean it and it worked for me. Theres a faom cleaner called Tuff Stuff. Just normal Tuff Stuff not special kind or anything. You will have to disasemble some panels from the car but you spray tuff stuff let is soak a couple seconds then take a soft bristle tooth brush or a soft bristle brush then scrub the stains. After that you wash it off with water, make sure to get all the tuff stuff soap out, thats why I say pull the panels off then use the hose to wash it out. Let it dry, then you use like a horse hair brush or a clean tooth brush to buff up the suede.

+1 on rebuilding it yourself.

Also, the wheels are on correctly. First new Z on here in like 2 months with the wheels on right.

Oh and this^

Looks very well kept. Mind sharing where you're from and how much you paid? I'm from Iowa and had to look all the way to Florida to buy my clean roller

[RED_DET]

Good information on the suede, I will give that a try because it is jacked up....

I'm not quite sure how you can put the wheels on the wrong way.

Rebuilding myself is going to run about the same amount as a rebuilt long block, the upside to rebuilding is you know exactly what is done to it and done properly.

I'm in KY and found the car in TN and it was a VA before that. One owner for the last 20 years and only two very small 1/2 dollar size rust spots at the underside of the rear rockers. The paint actually came back to life after a wash, clay, wax and more wax. I think all the contaminants on the paint over the past couple of years may of helped, however backwards that is. Paid 3k as it sits and everything works except the engine, even the bose radio/cd player sound good.

Any info on gpopshop.com? I spoke with them about the big 28 upgrade to the stock turbos. Goal is 400-500whp and I know the stock turbos will run out of steam around the 400 mark. Any other turbo options I'm overlooking? How about tuning? I have steered clear of JWT for sometime now with my sentra and went with a R/T ECU, so with that said is Nistune the better choice here?

[Z-owned]

What was Gpop's charge for upgrading the turbo's? May be worth just upgrading them as there are a lot of options for bb turbo's.

[RED_DET]

$695 a turbo....I haven't seen any turbo's that will support 500hp for that price.

[NolimitZ32]

The big 28 upgrade that you are talking about with make the turbos run at lower efficiency and will burn them out. If you're gonna do it, do it right or stick with stockers.

[BigTDogg (MA)]

The T28 in stock housings is junk for our cars. Terrible response and curve.

JWT isn't bad for Z32 tuning, but SpecialtyZ.com is the best. Contact Greg (email on the site) and discuss your plans with him. They also make the best exhaust products for our cars. See the post a few down from here "my new exhaust" or something. The downpipes belong in a museum.

Nistune is great if you do your own tuning. Otherwise try to get in on a group dyno day with Specialty Z (they fly all over north America) or Harry from Ztuner.com.

Sport 530/550 turbos will meet your power goals. They're ball bearing and will keep you happy for a while. I run Sport 500s I got used with 6k miles on them (why I went that route rather than 550s). Made 435RWHP, 456RWTQ at only 19 psi on 93 with methanol. Could easily get up to 22psi out of them, hitting the 500 mark.

Import parts pro (IPP) makes a great long block. Really can't go wrong with them. DIYing is always fun too

I'm outta fish for the day, welcome to the darkside

Oh, and the wheels are directional, they have L and R cast into them on the insides. The spokes are like fan blades which pull air off the brakes to aid in cooling. Minimal effect for sure, but thought went into the design

[DCaff300ZX]

Nice buy for $3K, and like Tony said- welcome to The Dark Side...

[CrazedZ32Owner]

WOW im surpised the drivers seat isnt ripped!!! O-o lol Nice find for the buck

I did not know that, who says you need to go to school to learn something new?? lol

[RED_DET]

The S15 GT28 turbo--14411-69F00, any input on this setup?

[NolimitZ32]

Decent turbo but will be a bit of a pain to make compatible with VG, the work you will end up doing will outweigh the cost saving and should only be done if you are good at fabbing. I'm running HKS 2350s that were originally assembled for a RB, I had to change out the turbine housings, fab waste-gate actuator brackets (since I had to clock the compressors) and make transfer plates for compressor inlets and outlets. I did it because in the end it was marginally cheaper for me, and because I love fabbing stuff it wasn't bad at all. All in all there is no real reason to buy the S15 unit because you can get a fully functional bolt on setup from one of the vendors and avoid lots of headaches.

[RED_DET]

Somebody talk to me about bearings??? OEM or "after-market"? Thoughts opinions, first hand experiences?

[Ace2cool]

OEM will handle whatever you throw at it.

[BigTDogg (MA)]

Engine bearings? Wheel bearings? Either way, OEM is fine.

talk to Kyle at IPP or Greg at SZ about bearing grades for your build if you're planning on building an engine.

[RED_DET]

Yes, I meant engine bearings.

[BigTDogg (MA)]

Yeah, didn't mean to sound like a d!ck, just wasn't sure what you were talking about. I probably should have scrolled up a bit and refreshed myself on the context of the thread

[RED_DET]

Well finally got the title all lined out and signed over after waiting for the duplicate. Vehicle inspection complete, so now I feel much better about investing time and money. First up an actual compression test was done today....
2- 70
4- 40
6 -50

1- 30
3- 0
5- 30

4 & 6 had mad amounts of oil on the spark plug, which I suspect bad valve cover gaskets, which is the least of the issues here. So removing the engine is up next....

[Ace2cool]

Yep, dead engine is dead.

[RED_DET]

What do you think? Head gaskets, rings or all the above?

[NolimitZ32]

Perform a leakdown, with numbers that low I would be looking at damaged valves

[Ace2cool]

That was my thought as well. Usually rings will leave you with numbers higher than that of your highest cylinders. That thing is shot dead. I'd suspect timing issues from improperly performed 120k, OR broken timing belt.

[Ace2cool]

That is, unless there's pieces of piston in the oil, in which case you already know what happened.
