when i did my SOHC to DOHC i had used an s14 long block bc i had a donor car. I used all s13 wiring and manifolds though. I did end up using the s14 MAF though. All i did was solder the pigtail to the harness much like doing a N62 MAF swap. It had no negative effects that I know of. I drove it like ...

if you are in there you might as well do them

Hes saying that parts will fail because eventually they wear out. Most parts of cars are wear parts.

i bought mine from JGS (forum sponser)

the s13 coupe i just bought had the same problem with the crank

Hey I just wanted to verify the differences in these two single cams. I just picked up an 89 coupe for 300 bucks but needs a new engine. I just finished putting an engine in my 94 d21(will be for sale soon). The d21 had a blow headgasket and rod bearing noise. This 240 has a heavy bottom end noise. ...

Generally a timing chain will start to make noise as it loosens up rather than just breaking on the spot. So like you said something most likely came loose or a tensioner failed or a guide wore out too much.

The stroker is going to require more fuel because there is more air inside the cylinder due to the volume change. You are still going to tune for the same AFRs as you would normally. Have you ever heard "no replacement for displacement" thats why you are going to make more power because yo...

what exhaust is that you have?

The compression ratio is a RATIO of two different volumes at to different points. You have your volume at TDC and BDC. Thats how you get your ratio. The area of the cylinder remains the same throughout, its the height at which the piston is at which is changing. The compression ratio should stay the...

heres a link to a post I did a while ago about what I did with my SR downpipe. I had a top mount so I dont know if you will have to extend as much.

I figured instead of cluttering with another thread I would just add to this one. I switched everything back to stock ECU, injectors, BEGi FPR, and MAF to see if the AFRs would be normal but its still rich reading a solid 9.5 to 9.6. Vaccum is around 19 (thought it should be higher), and its idling ...

im a virginia state inspector. as for adding a turbo theres nothing wrong with that. like stated above if you remove any emission you will not pass inspection such as cat and egr. other than that you dont need a muffler to pass inspection in VA but you can still get a ticket for it. never thought th...

is the fuel filter new? it could be a partially clogged fuel filter. if its a little old its a cheap part to install anyways.

haha man I didnt even think anyone was coming into this thread. its just me posting. haha no I havent but its up at my repair shop and its not smoking anymore and its AFRs are around 15 with the blowthru,injectors, and no tune. Im not driving it hard just in and out of the shop so we can work. Ive e...

the stock s13 gear ratio is 4.09 i believe. nismo makes a 4.36 i think.

thats usually a sign of blow by through worn rings. a catch can will always help but if its bad enough you might need rings.

Someone asked me and I wasnt sure but do DW injectors need impedence resistors?

I did some more tests on it. I pulled the rail and pressurized the system to check for leaks at the injectors and let it sit like for a while and developed no leaks. I had a BEGI fuel pressure regulator that I used before the tune still hooked up, so I disconnected that to see if that would make a d...

I finally got it back started and running again. I didnt get to work on it much since school and work was consuming so much time but I changed the spark plugs and that open wire above I checked with a test light and found it to be a ground so I spliced it to the MAF grounds. I have it at pull throug...

Make sure ground that is originally shielded goes to maf only and the other ground can be grounded to chasis. Don't put them together, I personally experienced a problem with this. Is this the sheilded wire you are talking about? This was inside a grey loom wrapped around the 5 volt and ground wire...

So i checked the wiring of my maf and i have it wired correctly. Im getting 12v to D but im not getting any volts or very little to B? What should be the voltage reading at B while runnning? I cleaned my plugs bc i knew they were fouled after checking the maf and then I went to restart it and it won...

what year wrx are they from? i believe the STI pink injectors are 550cc and they WRX are in the 400cc area. maybe if its out of the newer WRX they are larger ccs.

its a Synapse BOV ive been typing it wrong.

I got a tune from EFI Specialists. It wasnt tuned with the adj fuel pressure regulator in mind. What I meant by the custom tune was that he tuned it for the stuff I wanted rather than his normal tunes. I asked for 650cc injectors, Z32 maf to be run as a blow thru, and that I was going to run 12-15 p...

the 240 was what put the 300zx out of business it was a more afforable RWD fun toy Maybe they are afraid of the same thing happening to sales of the 350z or G35. I dont see why they wouldnt want to compete with the rest of the automakers putting out some RWD afforable toys.

JGS (one of the sponsers) has a good log manifold for DE or E.

have you checked your fpr?

I have a Bell Engineering Rising Rate Fuel Pressure Regulator that I was using before the tune. Should I remove that now that the computer is tuned? I havent checked the stock one at all though.

The idle is normal after I adjusted it with the idle screw but its still smoking bad and my AFRs are reading 10.2 at 800 rpms. I also forgot to mention I have BRK7Es gapped to .028 and a Synapnose BOV that was installed at the same time as the ECU, injectors, and MAF.

I started having this problem once I finally got my tune in. So the issue I figured has to be between the injectors, maf, or ecu. Anyways heres my set-up. Rev-Hard mani T3/T4 Front mount Z32 MAF (blow-thru) EFI Specialists Custom Tune 650cc DW injectors I put all new o-rings on the injectors when in...
