I have not heard any updates in along time from any of the kit owners. I remember that some were running way rich and others had dyno'd low. Well what is the latest, have you solved the issues, what issues do you still have? How does it run, what has it dyno'd, what were the A/F ratios, how about your gas mileage. How quick was it at the track, what boost are you running, etc? Any hints for those thinking of getting the kit, things to watch out for or any thing that will save us time? Thanks.

Well here's an update of mine... and what i'm going to do.

My car made low power at 8psi (with no smothing) I got 193hp at 5900rpm's and 204trq at 3600 and 4100... I have a dip in the middle... btw this is to the wheels.

I have a Walbro FP to install... But am in no rush...

I also orderd the LM1 Wideband and am waiting for it to get here... Then I can tune better... and see how lean or ritch I am... SOme members here said that some of my low power could be to rich...

I will be looking for another shop with a better tune setup to go to next time becus I did not like the fact I had no fan on my intercooler...

I'm still getting the stall if I push my enging to 4k and hit the clutch... I think its the MAF to close to the turbo... So I just dont do that and it wont stall... (I'm not going to work on this untill that guy on here comes out with his awsome looking GM? blowthroigh MAF... Then i'm guna get that)

Also I think my engine bay is getting way to hot... I can burn myself on both fenders and the front where the hood latches... To me thats to hot... I duno if thats normal.

Next I'm going to wrap the dump pipe? (bolted to the turbo) and the test pipe... I'm also going to order the greddy down pipe and wrap it also...

I'm also going to order a pyro gauge, oil pres, oil temp, water temp, intercooler temp in and out, plus a set of duel fans...

And I'm going to order a MSD with the 50k blaster thing...

I have also been looking into water injection systems, I think those will help me in my final goal. + I can use lean out my fuel a little and keep my engine cool with it... Thats just bad ***.

Plus i'm going to get a cryo 02 cooling system for my fuel rail and intercooler... I think colder fuel will make me feel better about my setup...

But I do have a current issue... The stock clutch I had installed 2 years ago along with my fadinza flywheel just lost its grip... I cant hit the gas hard or it just tears loose...

Before the turbo kit I got 20-mpg with the turbo i get 23-mpg...

Its going to take time for some of this to happen... I mean c-mon I just dropped over 5.5k on my car. Plus I might have to move to Spokane if I get this new job... So I have been putting $$ in the bank and trying to get parts at the same time... Not an easy task and I'm tired of top-ramen

Sorry to break it to you, I think the greddy kit is a waste of money. It seems Like a good deal, at first but then you get all these issues and under 200, hp? For that amount of money they should have their fuel system sorted out better.

I lost compression in 2, 3, and 4. New engine is going in next week hopefully. After that, I'll try to get all the bugs worked out. I have a z32 mafs waiting and maybe some 50lb injectors. I'm striving for 300 rwp on stock internals by the middle of summer. All I really want is a 12 sec timeslip. After that I don't want to mess with it too much. I need to stop spending time and money on my car and graduate asap.

Well I got my LM-1 today...

I'm guna try and pull off my dump pipe and get the bung installed this weekend... Or sometime next week...

Well, I bought the kit 1/2 yr ago, and I'm just getting it all together now. I'm uprgading the engine, and it should all be done by July or sooner. I'll let you guys know how it goes. This is what I've got going in.

The Turbo Kit w/ Intercooler itself,Crower RodsBlitz BOV

CP or Wiseco Pistons (I bought the CP's and Got the Wiseco's For free) 9:1 comp. I'm trying to pick which one I want

Blueprint and Balance with Crank Micropolished and DeburredToga HP BearingsCometic HP GasketPort and Polished Head w/ 5 Angle valve jobS13 CamsFull apexi GT exhaust (down pipe, and cat back) w/ High flow catFidanza Flywheel Nismo Clutch and Pressure plateNismo MountsDenso PlugsNology WiresASP Crank PulleyNismo AFR w/ 300zx FilterProfec E-01 with optional ign and inj harnesses

Sucks to hear about the running rich problems. Do you have the Profec on that?

If you guys got any suggestions on which pistons I should use, the CP's or the Wiseco's It would be grately appreciated. They are going in the engine in 3 days, so I'm still not sure which ones. The CP's Look better, more oil holes and all forged. The wisecos are coated. Both are same bore 89.5, and comp of 9:1.

Thanks guys

Yeah I have the Profec E-01... It would be kinda lame to get some other BC becus this one links with the E-manage and shows all the data / records data... Its cool.

It does make the car stand out a bit which I dont like...

Also yeah I hope my only issue is running rich...

Please please please be rich!!!

I do back fire and pop when I let off the gas....

I think thats due to the Turbo pushing 8psi and still spinning when the TB closes... pulling air past the MAF when the engine does not want it and making it real rich while the turbo slows down... And the raw gas hits the exaust causing the poping.

I think thats just a duh...

This also causes the turbo to surge... Which people have said its not good to hear the Cha cha cha cha of the wastegate... But it does sound cool.

Man I need to get a Type S...

I'm thinking of putting it on the hot side of the turbo down in front where you can see it... I think that would look cool, and would also be close to rout the waste back to the intake... Which I can move right next to it....

The reason I think it would be good there is thats the 1st spot the air would hit the resistance of the intercooler... and if the BOV poped open it should take the path of least resistance... Also this would keep my intercooler from cooling the air and keep my intercooler cooler...

Once I went to the Blow through MAF it would just vent to air. :ylsuper

What do you think about the BOV idea?

Also I think I can get my car running on the wadeband system tomorrow...

All I need to do is install the wideband O2 in my normal O2's spot... Take a head-phone jack and plug it into the output port on the LM-1 and tell it to give my car the 0-1v that its looking for...

This should also make my car run better all the time due to the fact it will now be getting all the data from the LM-1 and even at just 0-1v it will be dead on.

I can also run the second output to my Profec E-01 and have it log the 0-5v signal and convert it to real A/F right there... Thus I can hide the LM-1 out of site.

The BOV spot sounds like it would work. Most SR platforms do that, with the BOV befor the intercooler, but I have seen some do it on the other end as well. All the KA-T I've seen have the BOV by the battery, and if the recirculate they run a pipe or a thick pressure hose allong the front of the engine, where the old stock intake pipe laid.

As for the Wideband O2, will that really hook up to the Profec? Where does it connect to then? Also, the purpose of the wide band O2 is to show you if your running rich or lean... but it corrects this/ fakes this signal to the ecu (is that what the 0-1V is about?) Wouldn't a standard A/F gauge tell you the same thing?

I think I'm missing something :P

I have my bov on the hot side in the fender well. The problem with this is that its a little close to the turbo and far from the vacuum source so sometimes I get a little compressor surge. It does make it louder though. :)

Ok...

The Profec E-01 has 2 analog inputs (aka voltage) and the LM-1 (wideband 02) has 2 outputs (both can be programed)

So I'll just tell one of the LM-1 outputs to show the 0-5 volts off the wideband and input that into the E-01...

And the other output I will tell to do 0-1 volt so I can wire it into my stock ECU (becus our cars have narrowband 1 volt sensors)

I'm not sure how the car will like the voltage... Becuse the ECU is set up to see a certian ammout of flux in the signal... The wideband may put out to steady of a signal...

And no a normal A/F gauge is useless if it reads from a narrowband sensor...

BUT! You can use the same output wire that you attach to your ECU to run over to the 0-1 volt A/F gauge and then it will be accurate... (SPELLING ERRORS)

Also another thing that came up... The LM-1 sez not to put the Wideband 02 under the 9:00 o-clock position... And the greddy mounts the stock 02 at about 8 o-clock...

The reason for not being under 9 o-clock is to keep any build up of water from getting in the sensor.

Plus they say to put it far away from turbo's... becuse pressure could make the reading screwy

I'm thinking I'm going to get the Greddy downpipe and mout the Wideband 02 in it... (I can also heat wrap it before I install it (smart ehh?))

Also... I ran another compression test on my car (just to make sure my engine aint messd up)

the test shows the same as my 1st time... 192's on all 4

Right now I surge everytime I let off the gas... no BOV at all...

So anything will help...

BTW: did you just tap the BOV vacuum off the same hose your pressure sensor is on? on the FPR right?

Or is there another one easy to tap into?

No, its off that same series of vacuum lines though.

Man, I'm dying to get my car back up and running. This is killing me. All I need is some garage space and an engine hoist and I'll be ready to get her running again.

i have the greddy kit in my car, along with the greddy downpipe/ti exhaust and everything works great, the install was easy and straight forward. i might switch out the emanage for a jwt ecu though, since it raises the redline and has no speed limiter.

I can definitely see myself going standalone in the future. The emanage works fine, but I think I want some more control over timing and fuel adjustments, along with the rev & speed limits.
