Well my stuff came in today and I am coming down with severe turbo lag. So I am headed home early today to work on the beast!! I love warm weather!!

work onn the beast!

Installed the replacement FMU same problem fuel pressure won`t go over 55psi Oh well now I know it is my fuel pump. I tried getting one locally at a speed shop with no luck. Replaced the wastegate spring and tested it out it appears to be working now. The valve opens up like it is suppose too. Dam its a PITA to get that spring compressed with your hand and try to tighten those little alen screws on that wastegate!

SO Monday I wil order a new Walbro 255 and new sock like everbody else and be done with it. Next need to order 2 sets of gaskets for the 38mm wastegate. Tomorrow I will look at that oil pan leak again and see if I can figure out what I need to do to fix it.

The weather this weekend is suppose to be really nice and another weekend with out my 240

arent you using a mechanical fuel pressure gauge?

how were you able to watch the fuel pressure while boosting? were u at the dyno?

Post by **DammitBobby** » Fri Feb 04, 2005 2:44 pm

Let the car idle and put pressure on the FMU and watch the gauge. The FMU is suppose to raise the fuel pressure 12psi for every pond of boost. I put over 10psi on the FMU and only got a reading of 55psi.

Did you remove the mechanical fan for good? I hope you replaced it w/something to keep that puppy cool: those AC fan(s? S14?) won't do much good.

Keep us updated.-Jamie

Yes I junked it. It was in the way and made a lot of noise. I bought a NISMO thermostat and NISMO radiator cap. I only have the stock electric fan on it now. I haven`t been able to drive it much to test it out but so far it has been running normal temp. I am kicking the idea around buying a CF vented hood. I have been looking at a EVO and it comes factory with a vented hood and looks good. I will keep everybody posted on the temp factor when the weather gets warmer.

The stock temp gauge won't move until you go over 215F. I would leave the mechanical fan in.

good progress so far brooke!

I have been thinking about the idea of turboing the KA just cuz the BD kit is so cheap. But i want to know just how hard it is to do so. If you would make a newbie guide to installing the kit that would greatly sway me into buying it.

i have so many questions lol...

How much have u spend so far with everything ?How many miles on the motor ?did u pull the motor out or is it possible to install while still inside ?do u have a ?is it an s13 or s14 ?

bah, ill hold off until u begin the write up

Post by **DammitBobby** » Wed Feb 09, 2005 4:38 pm

Yes I am writing a how to guide. I am almost finished writing it but I keep adding to it. I will also include photos as well. I was like you not knowing anything and wishing there was how to turbo a KA for dummies. I will answer a few of your questions now.

How many miles on motor? 166k

How much have you spent so far? Not including the kit, I have kept up with receipts but have not added it up yet. I will guess probably another 400bucks and that includes the fuel pump I bought Monday.

Did you pull the motor out? No, you will not need to pull the motor out I document how to remove the oil pan without an engine hoist.

Is it a S13 or S14? It is a S13.

When will you get it finished? I have ordered an new walbro fuel pump on Monday it was shipped out Tuesday and UPS says it should be at my house Friday. If I get the pump Friday I will work on it Friday night. I hope to have the fuel pump installed Friday night and reinstall the wastegate Saturday morning. I will test drive it saturday morning and if everything is working I hope to have it Dynoed this Saturday. I will call tomorrow to schedule the Dyno run. I like to thank everybody for their patients with me. I know this project has taken a lot longer then it should have taken.

Hi there, Looking good! Hope to hear a full report once it's all said and done. Just a couple quick questions for 'ya... So the stage 1 kit does come w/a 12:1 FMU? I emailed BD and they told me fuel management was up to me, that I could purchase a FMU? Also are you running stock 270 injectors? Any piggyback EFC? I see you bought a walbro... other than the pump you are bolting this kit onto a bone stock setup(nothing else upgraded?) correct?

I'm interested in seeing dyno results for _only_ what's included in the kit.

Thanks for reading.-Slip

I see you bought a walbro... other than the pump you are bolting this kit onto a bone stock setup(nothing else upgraded?) correct? The only thing I have upgraded was the clutch. Last year it was slipping pretty bad so I replaced it with a Spec II kit. I also replaced the shifter with a B&M my stock shifter plain and simple sucked. No nothing has been done to the engine. I never bolted performance parts because I knew later I wanted to go with either a SR or KAT. After many months of reading on this board and talking to other people I realized that the KAT community was going to grow and I wanted to be apart of that. Not to mention the fact that it was going to be a cheaper and different. Everybody expects you to put in a SR motor not to many people know outside of our little community that the KAT has so much potential. Also it is a whole lot funner beating somebody with a truck motor

I really cant wait for your write-up. It would really help me alot.

GL with your install

Biiig weeekend for PJ.

Post by **jmwenick** » Thu Feb 10, 2005 8:59 am

Great job brooke and I can't wait for the write up, I am eventually going to go KA-T but i still have a lot of money to save. two thumbs up

Post by **slipnfall** » Thu Feb 10, 2005 9:31 am

Thanks for the response. I thought that the 8:1 FMU was used w/low boost[stock injectors]...

Also for those that havn't read there's a good thread w/info on the downpipe w/this kit at http://www.nicoclub.com/zerothread?id=101643 It only caught my interest because I'd need to keep the cat for smog purposes.

update?

Post by **GEO** » Sat Feb 12, 2005 1:23 pm

Brooke how did you make out today

Post by **DammitBobby** » Sat Feb 12, 2005 3:22 pm

Well seems like this project is never going to get finished. Ok here is the update.

Replaced the fuel pump this morning last night was COLD!! After replacing the fuel pump I noticed a few things. First the fuel pressure when idle was now around 39 PSI instead of 34 PSI. I cut the car off to get the air pump to test the FMU and I noticed the fuel pressure did not go to zero. The fuel pressure stayed at 35 PSI. With the old fuel pump the pressure would go to zero PSI as soon as you shut the car off. While applying pressure to the FMU with a hand held air pump I got it to go all the way to 100PSI. The old pump would never go over 55PSI. I believe now that the fuel pressure problem is solved.The problem I have now is that I lost my Firey Ring(Some type of washer that goes against the wastegate valve). I can`t bolt my wastegate with out that ring I have looked all over the place for it. I think I will just sleep on it and try to remember WTF I did with it So now only thing I have left is the Wastegate and fix the oil pan leak.

Well I am real depressed now. Another lonely no 240 weekend Another I am not finished post I really wanted to get this project done this weekend and give everybody the results.

Dont worry, my car has been down for 3 months, I feel as though I dont have a 240 anymore . Instead Ive been forced to drive my old crx around which broke down on friday, I can never catch a break.

My S14 has been in the garage for 10 months...I've had everything to finish it for quite some time now...Lazyness and lack of motivation is a biacth.

Post by **Structure240sx** » Sun Feb 13, 2005 5:26 am

Been there so many times in the past. there are always a ton of bugs to work out in the begining.

the walbro does the same thing to my fuel pressure at idle. its normal

Post by **DarkStar** » Sun Feb 13, 2005 7:32 am

Keep with it man. I've been following this post since it started. I admire your dedication to the project and really look forward to seeing the write-up!

Post by **DammitBobby** » Sun Feb 13, 2005 10:57 am

Thanks for all the reply`s. My frustration level peaked last night! I will attempt to contact a local speed shop in town that I met at the car show this weekend. They said they may have a 38mm fire ring laying around. I really hope so I am going to call them Monday morning. if they don`t have it I will call PJ and order extras plus some new gaskets. Don`t worry about the write up. I have it finished just need to add photo`s to it.

Post by **DarkStar** » Sun Feb 13, 2005 11:47 am

Awesome. Hope all goes well on monday!

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.....
