I have not worked on too many cars, but from my experience:

Hardest: 1991 MR2.

Easiest: 1991 RX7. Helped my cuz remove, rebuild and reinstall a 13B in his FC. Tiny little motor in huge engine bay = pleasure to work on. LOL

Wow. Tons of great info. Thanks everyone. :D I'm going to have to retract my statement about adding timing until I hear knock. I think im just going to create a safe tune, monitor with the DET can to make sure there is no knock, and leave it there. Wifey and I had a baby three months ago, so I cant ...

You are probably going to want to advance your cruise area. Thanks for the advice emo_tactical9. Ill take a look at the stock timing map and see where I can add some more timing in the lower load areas. I'm going to put together a DET Can within the next couple weeks so i will be able to slowly add...

I'll probably just do the tial or greddy rs, hose are the two I've been looking at. I haven't taken a look at synapse yet though Be careful if you find a used Greddy RS. I went out of my way to find one, and have had a couple issues. The main thing is that Greddy diaphrams are crappy. If you can bl...

Hey guys. I’ve been working on a tune for my setup and would like some advice and suggestions on my timing map. My motor is a stock 1993 KA24DE. I am currently running a 50 Trim T3/T4 with a .63ar turbine at 9 psi, and STI side feed injectors. I created a conservative tune and did some pulls to gath...

On the drive home from class today I stopped at a light, and my car almost went poop on me. Would barely hold idle at 450rpms and seemed to struggle and would be rich between shifts, also would bounce from rich to lean on the wideband after letting off the throttle on the highway. Get to investigat...

Just looked up the B6 S4 specs.
Impressive take down.

Thanks for the clarification Supa.
I should have looked more closely.

There is a small check valve between your intake manifold and the brake booster. I believe your vacuum block should be on the intake side of the check valve. Yours seems to be on the brake booster side. The check valve is supposed to close under pressure which would explain why your boost gauge read...

You probably just have air trapped in the system. I had a similar issue after i replaced my water pump and thermostat. The car would run perfect for miles and then start overheating. I must have bled the system a dozen times without success. I found that the bleeder bolt near the block sits higher t...

Welcome. This website is amazing. There is no other website that will help you through your KA build as much as this one. There is also a ton of general turbo knowledge as well. When your done, you'll feel like you could turbo anything. LOL I'm in Broward also, feel free to PM me if you get stuck. I...

Those correction numbers seem off. I think you would use -50% correction at idle if you were running 550cc injectors. You may be having an issue because of your in and out setting. I'm sure someone else on here can be more helpful, because I have zero experience with SAFCs. LOL Check out the link be...

does anyone still run calum? if so, have you all had any issues getting it to work on newer computers? i can get calumsult to hook up so i cant do anything Try what 8-bit said. Update your FTDI drivers. Go to http://www.ftdichip.com/Drivers/VCP.htm and download the "setup executable" file...

jholman05, Amazing work! That engine bay is immaculate. Also, props on your setup. Those quarter mile times, at relatively low boost on a T28 setup are insane. LOL Pballa88, I think that SR20 CXracing FMIC kit is a good start but it will need to be modified. Unfortunately, there aren't too many FMIC...

Whats up guys, I need a bit of help with datalogging with a CalumRT ecu. I understand this is ancient hardware, but hopefully someone can help me out. I have installed all of the software including Calumsult, Calumsult-LW2 Beta, and Calumsult-TP Beta. All of the programs are working properly, includ...

I was almost tempted to pick up a prepackaged turbo kit a while back, but came to the realization that I could piece together a higher quality kit, and pay either the same or just slightly more than those kits. I put together a complete turbo kit for about $2000 with quality parts. This is including...

That seems like a pretty sweet deal. Especially since they are high impedance and you don't have to worry about running resistors. I saw in your build thread that you are running an AEM top feed fuel rail. I would verify the opening size of your fuel rail. These injectors seem to have an 11mm top. I...

Awesome Numbers.
What trim is your T3/T4 and what size is the back housing?
Did you upgrade the clutch, or did you put these numbers down on the stock unit?

I would suggest replacing your fuel filter and spark plugs.
Then make sure your Coolant Temperature Sensor is operating within spec.

You should be able to tell by the differential or the axles. The tt model has a bigger diff with a different bolt pattern. The na output shaft or axles has 5 evenly spaced bolt holes while the tt has 6 evenly spaced bolt holes.

Im no 300zx expert, so dont quote me on this. lol

Like sdaigle240 mentioned. MBC's should help reduce spool time, not increase it. LOL I plan on running the NXS Motorsports MBC. I don't have any experience with it, but the DSM guys seem to love them. http://www.dsmtuners.com/forums/newbie-forum/304887-nxs-motorsports-ebay-nxsmotorsports-mbc-boost-c...

Shift, About your idle, you should check your spark plugs. If your actually running that lean, the tips may already be showing signs by turning white. If they look ok, you may have just developed a leak at the exhaust manifold after one of your pulls. Try re-tightening the exhaust manifold bolts and...

If I had trouble finding a used JGS Manifold, I would have bought this one: http://www.ebay.com/itm/1989-1990-1991-1992-Nissan-Cast-Turbo-Manifold-240sx-Top-M-Ka24de-S13-S14-T3-T4-/200818463639?pt=Motors_Car_Truck_Parts_Accessories&hash=item2ec1b69397&vxp=mtr It does come with some problems,...

You will be fine running N/A with the enthalpy ecu. Im in the process of turboing my car, and the first thing I did was install the STI injectors, N62 MAF and the enthalpy ecu. Ive been running this setup N/A for the last couple of months while I finish collecting parts. Car actually runs better tha...

I actually came across the same issue not too long ago. My idle would drop when coming to a stop and I knew it was my IACV. I took a trip to my local junkyard and pulled the IACV from a KA24DE S13 on the yard. When I got home and took the one off of my engine, I noticed that they did not match. The ...

There is a pretty cool event going on at Countyline Dragway in Miami in a couple of weeks. The event is being organized by "Street Racing Made Safe." They do half a day of standard drag racing, and for the other half they do roll racing like on the streets. I went to one of these events a ...

Poot: To answer your question about the tune, I emailed Martin at Enthalpy and he confirmed that the tune he sent me was correct for a N62 and STI yellow injector setup. Im not exactly sure what CCs he assumes, but if I had to make a guess, I would think he uses 525cc as you stated. As far as the O2...

Thanks for the suggestions schmauster920. I double checked my MAF and it is facing in the right direction. I am currently not running the O2 sensor. My motor is still NA, so I have my wideband installed at the location of the stock O2 sensor. Does running with the O2 disconnected put me in openloop ...

Sup everyone. I was hoping my first thread would be about my completed project, but im stuck on step 1 and need your advice/opinion. I recently installed STI yellow side feed injectors, N62, and Enthalpy Tuned ECU on my NA KA24DE. The issue I am having is that the car is running very lean. When i st...

You should always protect your ass seals from too much pressure. LOL Just out of curiosity, did you not run a restrictor? Im going to be running the turbo with a 3an line without a restrictor. I’ve read that turbonetics seals are good to 90psi, and my oil pressure never passes 70psi when Im at opera...
