my 240sx swap

[trick240sx]

tried to resize them a little. but here are the old pick and the updates. the weather is terrible so I havent done too much work lately. But if anyone has a fuel rail and # 4 runner to spare I would appreciate it. I few hidden hoses and a missed bolt resulted in a cracked fuel rail 2 broken injectors and a broken #4 runner.

looks pretty damn good.

Hows the exhaust gonna be routed to the back?

Is it a drag car only?

[trick240sx]

Im going to reroute the front break lines and run the exhaust outside the frame raissback under the car. so it will start out outside the frame rails and then go back under. I also need to either get a fuel cell or dent in the gas tank on the right side so I can run the dual exhaust.It is going to be street to strip. I cut the front core support out and all the excess metal behind the headlights and replaced it with a new steel cross member that can fold out of the way when work needs to be done.

[T45]

Hey trick I got your email. That thing is gonna be nasty. Mad props to anyone who tackles an engine swap in their driveway! It sucks working outside. Ask me how I know... lol

I'm gonna try and get my mounts done over the weekend and then jump on the wiring so I'll help wherever I can.

[DeXteR]

i officially hate you.

vert + vh45 = awesome

i've been dreaming about this swap for almost 6 months now. turns out someone beat me to it...

sigh...

that being said, you should definitely come check out the vert forum. i'm sure they'd be interested in seeing this project. in fact, i'm going to post a link about it.

props, good luck, and keep us posted.

[Florida240sx]

I got my fuel cell setup for $200 Cell was 100 and msd fuel pump was another 100

[trick240sx]

well I went ahead and test fitted the new front crossmember. I had one made of 1/4" steel since I cut out alot of metal. Plus I cut all of the area out behind the headlights. Now I can remove the bumper and fold down the cross member so I can remove and install the engine easily. Also I can get to the front cover to do the timing chain easily. I also modified the hood a little to allow it to close and provide additional air flow. All I have left is to cut off the ear on the right side of the trans because it is hitting the trans tunnel. and extend the trans mounts. My drive shaft should be done in a week and I should finish a moc shift linkage for the car. I would say I have a week before I can focus totally on the wiring. I also removed the gas tank so I can run dual exhaust out the back; I think for now i will run flex pipe from the turbos to the cats, and from the cats back to the mufflers to get it done sooner. I also cut down a front seat and made this vert into a 3 seater. you can partially see this in the pics. Im looking for a small fue cell for now just to run the car but I plan on cutting out the spare tire well so I can put a bigger more functional fuel cell in. better balance of the vehicle and additional weight in the rear end. This was the original project of slownferious from WV. QUESTION what is the temperature range for the oil. I have to hook up the turbos but Im tryint to use what I have availible. I found some dishwasher hoses with the braided metal covering. Its rated at 40 degree to 140. 180 intermitantly. Will these work. Also what port on the oil pump housing is the presurized side. I plan on tapping that port and running the feed to the turbos. Also Im using the T25/28 oil and water cooled. Is it possible to hook up a oil line to the water port so I eliminate the need to run water lines. Also my other option I was thinkin of was using hand bendable copper line to run to the turbos will this work or is there any problems with that. Also I plan on tapping the timing chain cover for my return line. Is there any problems anyone can think of. Im sure everyone saw my sneeky innercooler setup ie. factory 300zx IC's with high output motorcycle fans, what is the opinions of the turbo people in this forum. Will this make up for the small turbo size. Lastly Im hearing several different opinions on the MAFS before the turbos or before the air intake pipe. Can some people give educated factual information on this or real life experiences with the 2 options.

[Mettler]

Paragraphs, please!!

I'm interested in what you have to say, but my brain finds it hard to distinguish it line for line without getting a migraine >_<

[T45]

Your oil will get hotter than 180 so do not use those hoses. Stainless braid is more of a luxury on those items IMO. As long as it's an automotive hose rated for high pressure oil you're good to go.

I would just use rubber and double up the clamps at each barbed fitting.

[trick240sx]

sorry for not using paragraphs. I was in class and I had to get out everything quickly. My apologies

[T45]

How old are you?

[SeanDean]

Just get some -4 braided hoses on ebay, the Nascar teams sell them really cheap used.

[doctorchee]

hi first of all, i agree with Mettler, paragraph please. perhaps point form better?

i doing a twin turbo se up now also. Vh41dett. but incomplete at the moment. so share with you some issue on my mind after reading yours.

Intercooler - 1 or 2? boosting? guess if boosting at 0.7bar range, the inercooler works fine for 1 turbo. but its for 2 turbo, i feel not enough. simple as in can a stock 300zx intercooler supports 400 onwards hp? no

A/F meter - you still keeping stock ECU? or rechip? i suggest a after market ecu as turbo and na timing, ignitions, etc can be quite different. i guess it can run well, but a stand alone may be able to make the best out of it, or unless the rechip one can do the job well. also, not sure the rating for the A/f meter, but i think more than 420hp , it may have reading problem? why, last time i have many friends with Sr20DET and the a/f meter can't read after 350hp giving problems.

thats the 2 points running on my mind after reading.

hope it helps.

[T45]

Ah, lol I saw "class" and automatically assumed you were like 16 or something. haha I was like DAMN this kid is BAD! lol

[trick240sx]

for now I plan on using 2 turbos and 2 innercoolers. I spoke with JW Tech and they can flash my computer so the car will push out roughly 475 7 to 10 psi. That is all I want for now. I believe my set up will increase effiency.

Later I plan to upgrade turbos and innercoolers. But that will not be until I have this one dialed in.

have you ran into any other problems.

[Jeff Taylor]

Pretty cool project. I'd like to see how quickly those turbos respond with 4.5 liters feeding them.

Where do you live in VA? I'm down in Blacksburg and have a similar project to yours that I'm working on. If you need any tuning advice, let me know. I've been tuning nissan ecu's for a long time now.

Jeff

[trick240sx]

is that need Liberty University. My nephew is goign to school down there. But thank you for the props. I know the post is kinda sloppy but I wanted to post atleast something.

[Jeff Taylor]

Well, you do have to make sure it will run and work the major bugs out before the engine's appearance becomes a concern.

My swap looked like crap up until last month, when I finally got it running and had the time to go back, pull the engine, and clean things up.

So you're in Lynchburg then? Do you ever talk to Marshall, Nick, or Chris, who work on Nissans in your area? If not, head over to New London Dragway when the racing season starts again, Marshall runs it.

Jeff

[trick240sx]

I actually live in Northern Virginia. An area called New Baltimore. Its in between Warrenton Va and Manassas VA.

[trick240sx]

here is the intake I PLAN on having fabricated. It seems like it will be the least expensive way to simplify my turbo setup. It will also increase the intake size from 90mm to 120mm. I plan on using 2 ka24de throttle bodys to accomplish this while maintaining the Q TPS on 1 Throttle body. Any input or techincal reasons why this wouldnt work

[qsiguy]

lol, nice photoshop work. That would be a cool plenum for sure.

Maybe I missed it somewhere but what are those intercoolers? I have a rear mount turbo so I can get away with smaller than average so I may be able to get away with one of those. Is it a stock 300Z IC? What is the inlet/outlet diameters?

[trick240sx]

I believe the inlet and outlet are 1.75 or 2" i will check.Remember this car is being built for turbo upgrades, innercooler upgrades and so on. I know the intake will be larger than the turbo outlet and innercooler outlet but these items will not be perminant.

[crisj5]

ok where did u get the wire diagram i want todo the swap also but wit the VG30DETT and wat did u do to urs to get it to fit so well not to be a smart about it but did u have to make ur own cross member.. email me at [email protected]

[trick240sx]

the crossmember I originally had box steel welded to the original crossmember but I changed over. I got 2 pieces of 5" X 4" half inch thick. I then bolted the existing Q motormounts to it. Then I lowered the engine in to the point of touching the crossmember and marked the holes. bolted it in and that was in. The steel is thick enough to support the weight but I will have more supports welded in later. As far as the wiring I ordered the wiring diagrams online but I havent got to the point of spicing yet. That is about a month away. I need to finish the DS, have the flange welded on to the water pump, and have the intake manifold finished. Once thats done I will complete the wiring. I also need to have a 29X20X10" gas tank fabbed. I dropped the factory tank so I could run dual exhaust.

[trick240sx]

well the manifold was dropped off today for welding. I was told it should take about a week. Next they will weld up the water pump. Lastly the will weld up the drive shaft. Props to Dexter for the trade of 240 TB for a Q TB. These things are done I need to install a temporary fuel cell and complete the wiring. Just to give an update.

[hannibal]

about your manifold... Nobody else mentioned it, but to me, it doesnt seem like a good idea to have 2 TB's sharing a single plenum. Wouldnt that cause major turbulence above the runner entrances? I cant think of a OEM intake like that, NA or turbo. Each throttle body usually leads to a separate plenum with ruuners for a single bank (VG30, BMW V12).

[trick240sx]

that is a possibility but if you never try you never figure out new things. Im thinkin that because of the design of the intake even if there is terbulance if equal presure is sent from each turbo it should equal out between the 8 intake runners. I mean there is nothing in the intake diverting air one way or another so logic would say that the rear 4 ports or the whole right bank would recieve less are flow than the front 4 or the left bank. If it was a NA engine it may cause a prob but forced air I do not believe it will cause a prob. Like electric air should take the path of least resistance. If Im wrong I will find out soon. Im running a active O2 meter on each bank to monitor the FA mixture. I will let you know if one is running richer than the other. If I have too If there is a problem I will have he manifold cut in half and have a plate welded in and then have it welded back together to seperate it 2 seperate intakes. Air flow is increase either way. The shop Im dealing with is sponsoring me so instead of 85 an hr its 40 an hr.

[trick240sx]

here are some more picks. You will see the adapter block for the electric water pump. the water pump is a CRS electric water pump for a LS1 engine. Then you will see the manifold by itself. It has a like coat of high temp paint. Im gonna do the same for the cam covers. I think it looks pretty good. The next pictures will be the manifold with the throttle bodies attached to the plates. I figure out how I was gonna run both. I am going to use a similar set up of the original manifold. instead of using cruise control on the left side of the manifold I will use that cable for the second TB. the rest of the pictures show the routing of the intake piping. For a do it yourselfer its easier. I also had a v cut on the new side of the manifold to reduce the turbulance and airflow difference on the new side. Hope you enjoy.
