Ok so my motor has low compression across the board (125)

[300ZXttZMAN]

And im getting some prices together to see what im looking at and here is a question i have why does it say that these turbos are for offroad use only ???
http://www.importpartspro.com/1104rn041.html



Im thinking about getting a loan from my dad and just flat out fully building my other block from my parts car.. When i say building i mean stricly doing only the things that you have to do with the motor out of the car or the things that you have to do inorder for it to run properly for example ecu upgrade and injectors

[a.blanco0905]

^Wow Mark, seems like you're going to go all out, good luck with whatever you choose. BTW they probably say "off road use" because either, 1. They're not street legal or 2. They wouldnt pass inspection to be on a regular driven car, and "off road" doesnt mean to go off-roading but tracking...

[300ZXttZMAN]

hah yea man i figured that but i want to know exactly what that means does it mean they will give you way to much horse power or that they wouldnt pass emmisions BUT WHY ARE THEY NOT STREET LEGAL !!!???? But yes as far as going "all out" i would like to have about 600rwhp by the time its all said and done (end of summer) but as far as like the middle of next month be back driving her again

[NolimitZ32]

They aren't street legal because they aren't EPA/DOT approved for use on the streets, it doesn't mean they cant be it means HKS didn't go through the trouble/cost to get them tested/approved. A sidenote: Personally i'd go with the Greddy/Trust MHI tdo5-16g kit. Way better flow efficiency than anything Garret makes

hmm nolimit can you give me a link to those turbos

BTW I JUST TALKED TO MY DAD AND HE SAID THAT HE DOESNT HAVE A PROBLEM WITH LOANING ME THE MONEY TO DO THIS AS LONG AS I LEARN HOW TO DO IT AND ACUALLY DO IT HANDS ON.... GAHH IM SO PUMMPEDDDD

NOLIMIT WHAT WOULD YOU THINK ABOUT DRIVING FROM HOUSTON TO COME TO SULPHUR (2 HOURS EAST OF YOU) TO COME HELP ME AT A COUPLE DIFFERENT POINTS DURING THIS REBUILD. IT WILL BE YOU AND I AND A COUPLE OF MY FRIENDS ILL PAY YOUR GAS AND I WOULD GREATLY APPRECIATE IF YOU WERE ABLE TO COME AT DIFFERENT STAGES DURING THIS BUILD.


On a side note sorry for the caps lock but you have to understand how excided i am

[NolimitZ32]

I hear yeah man, and yeah if its the weekend and I'm not busy I would have no problem at all coming down ( although I would have to hit up LC for a few hours to go throw some cash away lol. Since Greddy/Trust has closed their doors these are harder to actually come by but here's a link i found on google, if you want more info on the particulars of the kit talk to tommyzx, he is running this exact kit on his car.

These kits are retarded expensive but they come with everything. Not saying HKS kits aren't great because they are I just like the feel of a setup such as the TD05s.

[300ZXttZMAN]

hell yea haha i live in LC Our salvage yard is in sulphur i make the drive everyday from lake charles to sulphur not bad at all ha but the problem is im not 21 so no casino for me but we could go by boat when you come down thats always fun

but yea ill let you know..

But i need to start figuring out my motor build cams, cam gears, down pipes, turbos, injectors, ecu,, all that good stuff

[NolimitZ32]

This is the fun part, better gets to reading man.

[BigTDogg (MA)]

IMHO, GReddy turbos are nice, but old tech and way too expensive.

MSP Manis
28RS turbos
Ash 2.5" piping and ICs
Ash 2.5" inlet piping
SZ 3" exhaust

will give you monster power and great spool

Peak numbers mean doggpoop compared to the actual power under the curve. 600RWHP will require built internals to be run relatively reliably. And that would be for a race fuel tune. 600RWHP on pump gas is gigantic dollars.

[NolimitZ32]

^ I agree with everything you say there 100%, only reason I love the 16G kits is because of the way they spool/flow, I swear like the LS1 is an engine made by god, well the TD05 16G is a turbo made by god, they flow sooooo much more then any turbo in its class and and they do it very very well especially since they are old tech. And i'll be the frist to say that the Greddy kit is super overpriced, in fact I've actually talked to turbochargers.com about building me a set of 16G compressor/t25 5-bolt turbine units so I could spend 2gs on new BB turbos vs having to drop 8gs on the kit. Like I said It's time for yous to gets ta readin so you can figure out what you want.

[BigTDogg (MA)]

^ I agree with everything you say there 100%, only reason I love the 16G kits is because of the way they spool/flow

And being EWG they sound amazing as well

There are some other newer turbo options which outflow the TD kits, like the billet turbos. I'd really love to see a T2 housing VNT turbo option.

hmm ok change of plans i have about 6k to work with here is what i have to get engine rebuild kit proabaly from

THis rebuild kit > unless someone knows a better one http://www.conceptzperformance.com/Cart ... 9.12.25.68

I just dont know about which turbos i want

also im getting a new oem harness for $399 from mynismo.com

[300ZXttZMAN]

i want to get a turbo that spools up quick and will sound awesome on the vg

That should be a decent rebuild kit.

Get your harness from Bernie, I think he does it for $405 shipped ($5 cheaper than mynismo). Definitely get the 95 harness and 95 740s. Again, more reading and searching as Anton said http://www.yugobernie.com/harness.html

Sport 700s (GT28RS) get my vote. Can easily do 500RWHP on 93 octane with the breather mods I noted. 500RWHP will get you a mid to high 3 second 0-60 run with good traction and driving skills.

Are you doing all the cylinder boring yourself or leaving that to a shop? It requires specialty tools and may be best left to a pro. Though the rest of the assembly is rather straight forward.

second to everything this guy says. 6k bucks+ won't get you 600rwhp+.
you go through money like it's nothing on this car, turbos, 2.5'' ic pipings and ics are 4.5k bucks+ already. and that's assuming you do all the labor yourself.
then clutch to hold the power, ebc, exhaust, radiator and oil cooler, etc.

imo, for 6k, get a good-compression motor/engine, upgraded ic pipings and ics, exhaust, ebc and get a tune.

[Chattzx]

0-60 in the 3 second range would be boss status.

[legion]

+1 to the sport 700's. I have the z1 675rs kit which is roughly the same and the spool up is insanely quick with the breather mods mentioned. They keep pulling from 3.5k all the way to redline!

What are the main things that would make a pump gas car with 600rwhp so $$$$?

Just for the record, my head just exploded. I would have never thought of anything like that.

man it just keeps getting more expensive! i was planning to do the MS manifolds, 675s, and a full 3" SZ system here in due time. now it looks like I need the full 2.5 intake and charge piping as well. sigh.

[300ZXttZMAN]

hmm well im deffinately getting new turbos (that our upgraded) with my motor build

Could i go with sport 700's i like the way they look and the price is not bad could still run stock injectors and only would need a tune??

[NolimitZ32]

No stock injectors on anything bigger than the 530s, even 530s I wouldn't run stock injectors on, if you get 700s you need min 740cc NISMO injectors.

[300ZXttZMAN]

okk s*** thats going to jacking my cost up

[BigTDogg (MA)]

Just for the record, my head just exploded. I would have never thought of anything like that.

Apparently neither has anyone developing Z32 turbo applications They would be amazing to have on our cars, providing the best of both worlds with stupid fast spool and freight train pulling ability.

740s would be a good start, but IMHO, if you're looking for big HP, I'd seriously consider the BDE top-feed rail with the 1000cc/min ID injectors. Easier to swap out, huge flow capacity and lower relative cost.

You would need every kind of flow mod there is. Built internals, headwork, bigger turbos than you would need with a race gas tune. Race gas allows you to push the engine to it's absolute limit without the fear of detonation. Pump gas you don't have that luxury. With the saftey margins required for PG tuning, you lose some potential for the sake of safety. I'd be shocked it the GT28RS could hit 600RWHP with a safe tune on 93 octane fuel. Not saying it can't be done, but I'd be surprised for sure. Bigger than that and you're looking at Z1's GT800 kit, or SZ's EXP-90, both of which bring serious lag with them.

People often toss around 600RWHP or 700RWHP without knowing what that power brings. Not specifically targeting you OP, just saying in general. 700RWHP is where you start having manual transmission issues. Autos need to be upgraded long before that. Then you neet to worry about half shafts if you're drag racing. The safe limit for the OEM TT fuel pump is somewhere between 650 and 700RWHP.

IMHO, when approaching a build, it's always good to have goals. But rather than having a number as a goal, I like to think of what the car is intended to be used for. If you want a car that is super responsive and an absolute blast on the street, then I'd get the full 3" SZ stuff, 2.5" IC and inlet pipes, Sport 550s and call it a day. Maybe get Leader Gears if you can find a set. Then you'll have less lag than stock with a reliable 500RWHP all day long. If you want to built a drag monster, I'd get a built SZ auto transmission, EXP-90 turbo kit, all the aforementioned breather stuff, 1000cc/min ID injectors and BDE rail. That'll get you mid to low 10's all day with a decent driver.

More data (if you need it): my old 91TTZ with the 3.69 TT rear end with 320RWHP and 355RWTQ had a best 0-60mph time of 4.43 seconds in 55°F air. I haven't run my new car yet, but with 110+ more peak HP and TQ, and equal torque 1000RPM sooner, I expect very low 4s, high 3 second 0-60 runs. See below:



Long story short, there's a lot more to a build than a peak HP number.

[NolimitZ32]

I'm converting my car to pintleless injectors, i'll be running stock Legacy GT yellows (jecs 505 cc) you should look at maybe getting the yellows and modding them such as described here: http://www.witchhunter.com/subarumod1.php4

The yellows are physically the same as 94+ ones and can be used in the early style plenum/rails with the $120 adapter kit sold by Z1. Now you're asking why the hell did I just go into all this, because the LGT yellows can be had for $120 for 4 (used) which would mean $240 you would have a set plus 2 extras, then you could get them modded to flow 800cc. I'm going this path because I don't need to mod them and end up spending much less than if I were to buy NISMOS (which are exactly the same units, same JECS pn). But yeah there ya go, just a suggestion for you, do some research. 300zx aftermarket parts carry a huge premium because they are "300zx" parts when in fact lots of stuff (like injectors) can be had for less elsewhere.

Topfeeds is something else I have been considering and yesterday found a local shop that can mill me fuel rails to my spec so i am currently looking at doing that as well. BTW if this goes well I might start selling them.

[ztommyx]

wow... not dissing on Greddy TD-06 Twin Turbo kits or anything, but i do have that kit on my Z... 10+ years ago, so it's old school.
it WAS one of the better turbos out there at the time but a lot of race machine and shops start coming out with better turbos and better price.

though i don't regret getting the Greddy TD-05 kit, if it were TODAY, i'd go with something different.

about the Greddy TD-05 Twin turbo kit, it sure lag a bit, but it could be my FMIC? or a few of my mods? this i do not know...
but once it kicked in, it flies

i bought the full kit for about $4,000 (at dealer cost as i used to own a shop), the price has gone up. its insane.
everything cleared and bolted up nicely. dropped in nicely with new motor mounts.

OK so time out lets see so nolimit and bigtdog like the idea of me going with sport 700's and nismo 740cc injectors with the new style fuel rail adapter kit

I like the 700's because they spool up quick and hold boost longer who wouldnt love that. But here is the ultimate question will i be able to use the 700's with nismo's 740cc injectors. With stock intercooler/piping stock manifolds ecu??? If not what more mods will have to be done?

On a side note: Eventually i will be upgrading to hks fmic and upgrading piping. But for the time being will those mods work with those stock units??

[vulcanrush]

No stock injectors on anything bigger than the 530s, even 530s I wouldn't run stock injectors on, if you get 700s you need min 740cc NISMO injectors.

i wouldn't run stock injectors on ANY turbos, even stockers.
iirc, they're good for up to 370-380rwhp+.
and stock turbos can do that for sure and then some, as we've seen with recent dyno charts.
also, stock injectors, unless you have a 1995-1996 model, are the older style that don't like ethanol gasoline too much.

sport jwt700bb turbos DON'T spool up quick without supporting modifications.
i.e., 2.5'' ic pipings and ics, msp manifolds, and 3'' exhausts.
YES, you can use the 700 with nismo740cc fuel injectors.
if you're staying with stock ics and ic pipings and manifolds, get a smaller set of turbos.
