Almost Finished KA24DET!!

[Zyphar]

keep at it brooke!

its just two small things left before u have a sexy looking KA-T ! cant wait to see some pics of the beast and how its sounds (hopefully some sound clips =D ).

just another quick question, How was your engine doing before u started the project ? Did the chain rattle at all ? is the motor running smooth ?

hey don't feel so bad about it. when I put the Greddy kit on my car I though it was gonna take me 4 days tops, A screw up with some manifold studs from greddy in the kit witch took forever to figgure out who was responsible for (me the sales pople or greddy) a headache in itself, Then a broken headlight that as I was looking at the d@mn thing to get the part number off of it (the moron from our local nissan dealer told me the part number would be on the assembly witch it wasn't anyway) well talking on the phone and looking at a busted *** headlight (kouki =$245) I droped the assembly and cut my hand (doctors bills =$250) to stick a needle in me and sew my hand poorly because it was such an odd place to stich up and they kept pulling it back to get at it (between my thumb and hand in that webbing because I actualy caught it for some Dumb Reason ) and well you could see my bone so that led to more down time because I couldn't wrench. And this whole time I thought I was insane because greddy sent the wrong studs in the kit and I would have swarn to god that I had the bolts on the mainifold that hold the turbo down during the mock up but lost then and couldn't figgure out why the ones I kept buying Didn't fit and 400+ minutes on my cell (hold time Included) and a picture sent next to a ruler to prove that the wrong studs were sent to begin with I was back at the SOB only 5 weeks later then I had thought, oh yeah I was also clueless that the oil pan had to be welded not just drilled out and a fitting could have been installed so it took me a few weeks to sorce a welder and git that done, finaly back at the game we get it fired up and idels just great but dies as soon as it gets gas turns out some wire was striped that wasn't the right one but was notticed on the check and was solderd to the right wire but was eletrical taped poorly and caused some odd ground issues was out guess but fixed none the less by this time I was 2 months into the damn thing and still working out bugs and by the time everything said and done I couldn't afford a BOV or Fuel Pump but any way keep with it cuz I tell you there aint Nothing like the sweet sound of YOUR turbo spooling up (even without a BOV:rolleyes ) I Tell you that in the end its all good well at least it was untill winter came and then I had ACL surgery on my left leg and well thats the clutch leg yeah i'm better now but I live in Wisconsin and screw salt getting on my baby! any way as soon as its nice I'll be at the wheel (after a few things) so I feel your pain too ne ways Good Luck on the ride and keep it up KA_T Shift_Rock

ummm, 100psi....... is this the fuel pressure that you will be at once your car is at wot driving? factory wot fuel pressure is 43.5psi IIRC. is this safe? will the injectors operate in these conditions? a friend of mine bought a nismo fpr to keep his fp constant in his sr after he installed the walbro 255.

maybe i missed something.....

Yes 100PSI you didn`t read wrong. I am using a FMU 12:1 disc. For every 1PSI it raises the fuel pressure 12PSI. This is because I don`t have bigger injectors and some type of fuel management. Now you are asking how did I do that? I have a hand held pump that I applied pressure to the FMU with the car at idle I disconnected my pressure source and connected the hand pump to the FMU. Then I applied pressure and watch my fuel gauge pressure go up as I applied pressure to to the pressure source on the FMU. This was only a test to see if I could get more then 55PSI. As in my previous post my stock fuel pump and FMU would only raise the fuel pressure to 55PSI. Now this was only a test the fuel pressure jumped to 100psi and went back down quickly. I wasn`t using a constant source of pressure because it was a hand pump and once the trigger was squeezed the pressure drop so you have to squeeze it again and again and again. Because the fuel jumped quick up and down it didn`t stall the engine. However If I had used a constant source of pressure the car would have blown black smoke out the exhaust and would have stalled out. Now the next question everybody ask, isn`t a 12:1 disc to much fuel? Hmm, could be I don`t know yet because I haven`t been able to get back to the Dyno for the 2nd time. Then comes the next question how are you going to adjust the FMU if it is to rich because there is no adjustment? 2 things you have to do. 1 buy a valve from your local aquarium shop don`t know the name of it but will provide a pic of it. 2 have to go to the Dyno and adjust the valve until you get the best A/F. Now you are asking where does this valve go. Simple you disconnect your FMU pressure source and T this valve in so that you can bleed off PSI source to adjust the amount of pressure the FMU receives. Think of it like a boost controller it really does the same thing.

just another quick question, How was your engine doing before u started the project ? Did the chain rattle at all ? is the motor running smooth ?

Thanks, I will do a video but have know clue on how to post it maybe someone can help me when I get it finished. I am actually thinking of taking a camera that can do videos( I know the quality sux but it is smaller file) to the Dyno so everyone can see how it goes. Hmm even thought about taking the camera on a Friday night and see if I can find some action nothing over 80mph on a highway. I might consider a roll from 30mph to 80mph and no higher. I rather do my racing on the track where it is safe and fun but every track around here is closed for the winter.

just another quick question, How was your engine doing before u started the project ? Hmm I really don`t know with 166k on it I guess it ran ok. I never did anything in the engine. Only problem I remember is that it hesitated at around 5.5k RPM which would have been that old fuel pump.

Did the chain rattle at all ? Yep still does

is the motor running smooth ? Right now it seems to be I will let you know when I get the wastegate installed. It seems like a lot of people have that idle problem or stumbles at certain RPM.

[DammitBobby]

Dam Turbo98 I guess I shouldn`t complain I haven`t damaged any part of my body yet! Other then a few scratches and bumps. May be we should start a post of all the screw ups everybody runs into. Has anybody ever installed a Turbo on a KA and not run into any problems???

[ILikeMy240sx]

I never knew that you could adjust the FMU with a valve.

Learning something new everyday!

I cant wait for your setup to be finished and be dynoed. I really want to know how the FMU will do at the dyno... Very excited

I installed my turbo kit in 2 days, started it and drove out the garage the first time she was fired up untill 8000 miles later it blew. It was to good to be true, Its been downhill since, but its all worth it when your smokin a 03 carrerra like nothing

Well orderd my firey ring and some extra gaskets(23bucks and 7 bucks a gasket). It should be in Wednesday. I checked the weather it is suppose to rain this weekend I guess I will take off a few hours early this week.

[GEO]

I hope PT doesn't run into any problems

[240SicknessX]

considering fp is 43.5psi stock at wot, and you have the 12:1 fmu disc in there, and your wastegate is suppost to open at 8psi thats 96psi of fuel increase and if you add in your base 43.5, you are at 139.5....... something dosent sound right, when i was reading about injectors somewhere, if the fuel pressure is too high it will not allow the injector to open. maybe i got some bad information somewhere, am i doing my math wrong for the fp?

[ILikeMy240sx]

I remember Ivan talking about that issue... how the fuel pump/injectors will not be able to handle the pressure at that boost....

Im waiting to see what actually happens

[240SicknessX]

IMO i wouldnt run the car at 8psi with a 12:1 disc, thats just too much fuel pressure, i would possibly advise a more secure way to tune that. sr injectors are around 100 and safc off ebay for 200-225. i would rather invest in a more reliable fuel system then have to rebuild a motor.

*hijack thread*- like the walbro 255lph, it is known to raise the stock fp and to keep it at the factory 43.5 an adjustable fpr needs to be installed to correct it, if i got or found a z32 fuel pump would this also raise the fuel pressure because of the added volume like the walbro or will it stay around factory 43.5?

[DammitBobby]

UPDATE!!I picked up my firey ring and gaskets today. I couldn`t get started until late tonight. I had trouble getting the gasket between the downpipe and the wastegate. So I said F****** I installed it without the gasket! I cranked it up and it sounded good. I moved my daily driver out of the way and headed up the street. Then it hit me I forgot to hook up the hose from the wastegate to the hot pipe. So I stopped the car and pop the hood next to a pole light. While I was hooking that back up I saw a whole lot of smoke going everywhere. Dam oil burning everywhere. Need to fix that oil leak! I was hoping it would not be another bad sign yet again. I hopped back in the car and headed down the street and took a turn. Then I punched it in second gear and the tires broke loose as I was trying to keep the car straight. Then I hit third and thought the car was going to come apart! Dam I was going fast. I could not believe the difference!! OMG I was not expecting that !! It pulled hard!! Don`t ask me what RPM I was shifting or what boost I was running because I was more worried about the car staying on the road. I need to get rid of that open differential.

Cross your fingers and lets hope the car does not catch on fire before I get to Trussville(30 miles) Friday for a dyno run. I did notice after boosting the car started getting hot. I hope it is not a big problem.

[Tictakman]

ya they do get hot. and yes the open diffs suck. i just swapped in a j30 and its a world of difference. night and day. now im in need of more boost.... my tires dont help the traction issues either.

Zak

[DammitBobby]

I am now going to have to research replacing that differential and those tires. There is no point in getting anymore HP, it would be all wasted on the pavement. Another thought how are you going to drive something like this in the rain? If you get into boost in the rain you are going to kill yourself!

I thought about the gasket problem last night laying in bed and I came up with an answer. If I had to do it again I would use sewing thread and tie the gasket to the downpipe through the bolt hole. That way it would stay in place when you try to bolt the wastegate on. It really is amazing how many things I fix laying in bed relaxing. Dam they need to get me a bed at work and let me sleep!

How do we post video`s? I have a Dyno appointment Friday at 4:00pm and I want to use the video function on my digi camera. I also want to record a couple of test runs.

[virus77]

As I recall you dont have a fan. I strongly suggest you get one.

[DammitBobby]

I have a stock electrical fan. I might buy a better one or wire the one I have to stay on when the ignition is on.

[GEO]

hmm.. i m interested!

[nissanfanatic]

Definately definately get a fan. Re-install the clutch fan or something.

The added pressure on the fuel system directly goes on the injector pintle. If the pressure is too high, the pintle will not be able to open resulting in a "dead" cylinder or lean condtions if it opens slightly. Not good. I would back the boost off to around 6-7psi just to be safe until you take care of the fuel system. Good luck with the car. I'm glad you're enjoying it.

Solution for driving safely in the rain:STAY OUT OF BOOST! Even with my rinky-dink setup, I can spin the tires at 70mph in the rain. Its a lot of fun, but isn't the smartest thing you can do.

[slipnfall]

I didn't re-read over the previous posts, maybe this was covered. This issue with high fuel pressure could be solved with 370 injectors and a lower ratio FMU, correct(8:1). How would this match up with the BD kit if one were to take this route?

Thanks!-Jamie

[crzycav86]

I think if he had went the 370 injectors route, he could have ditched the fmu altogether. The problem with bigger injectors, however, is that you need an safc or ecu retune to use them... which adds to the cost of the whole project.

[slipnfall]

Ah, roger that. Yeah 370's+FMU=too much fuel, wasn't thinking. I assumed since rseabrook was doing all this dyno time that he/she had something to tune with anyways....unless of course the dyno turns out to be satisfactory. Around here, 3+ trips to the dyno would pay for SAFC+370's...

Interested in seeing those dyno results. Do you have a personal internet service provider rseabrooke? Usually they will give you some amount of space for a web page. You can upload it there. Give 'em a call if you're unsure.

[DammitBobby]

I am leaving in a few minutes. I will post the dyno on cardomain and link it. As far as the video that will be the problem. Yes I am going to tune it because I have a valve that we will use to turn down the 12:1 disc if we need to change the A/F. Remember all actuated devices work on pressure any of them can be adjusted with a valve. I am suppose to be at Walker Dyno at 4:00pm in Trussville if anybody around AL wants to come. I will take pics and video. I just hope the oil leak does not get any worse.

[npaulseth]

Good luck.

[GEO]

I can;t wait!

[ILikeMy240sx]

wow.. Stage I kit and you feel that much difference... thats awesome..

I cant wait to hear how FMU setup does at the dyno

[DammitBobby]

91 S13 Stock KA24DE 166k Stage1 Boost Design kit (8PSI) Fuel Management FMU 12:1 Walbro 255 MSD SS Coil SPEC II Clutch B&M Short Shifter BRM 2.5 Dual tip exhaust 3 inch crush exhaust connect 2.5 exhaustNo Clutch fan Open differential Timing chain makes noise Bad bushings rear end suspension Stock timing. NGK BKR6E-11Spark Plug gaps .32 Dyno Results by Walker Dyno (Blake)

My first impression driving the stage 1 kit. I could not believe how hard the car pulled all the way to red line. This thing has turned into a torque monster! If you have an open differential forget starting from a dead stop! My car started bouncing and going all over the road.

Dyno Day!!After the Dyno run I talked to Blake(Dyno Tuner) about the engine. He said that we did not need to do anything with the FMU that it had a good fuel curve. He felt confident that we could up the boost safely to 10PSI and possibly 12PSI with the current system intact. The Dyno sheet represents BoostDesigns Stage 1 kit with no tuning at 8 PSI. At the dyno we tried messing with the boost cheezy valve controller with no luck. The problem we ran into was the wastegate did not want to open. So we had to take the valve back out but the valves did not rattle until 14PSI of boost. One of the runs we had showed about 30hp more on the chart. We just could not take it all the way up because of the wastegate not working with cheezy valve. My compression tests I did a few weeks ago were around 155 with oil added it went up to 180. Which is not real good. So we pretty much think this motor is on its last leg. We don`t care because we are going to push the boost. PJ`s statement that "Boost is addictive" is an understatement!!

Can you get a blown up version of that graph? It's really tiny...

What numbers did you end up getting anyway?
