my motor just went a week ago just found a nice front clip of a 3.5 i had a friend help me out drill the cams and swap sensors over

i was just wondering do we lkeep the 3.5 injectors harness or the 3.0 connects to it also for the throttle body if im usin the stock 98 do i need adapter plates do i need to get a walbro and a fpr and a rpm switch to drive the car?
where could i get whats needed

 

im pretty sure the 3.0 injector plugs and 3.5 are different, just like the DE and the DEK plugs are different, top feed vs side feed...

I would just get the plugs and soldier them onto ur 3.0 harness.

Dont take my word for it tho..

 

What s0ber said, plus

-You can use ur stock TB, but it might be kinda small, and yes you would need an adapter plate. I suggest converting the 3.5 TB to cable, that way you get as much air in there as possible, AND no adapter plate needed.
-You can keep your stock fuel pump, but an aftermarket FPR seems is necessary, StephenMax figured a nice way how to install it, you'd have to look for that, I believe its on the thread of Dubeya's (sp*) swap.
-Yes you will need an RPM switch for the VI, Unless you plan on getting a VAFC, or EManage, which can control the VI on their own

Take pix of the progress

 

That's what I did. Painless and effective.

 

what fpr can i get and is the easiest one to install the vi is the 3.5 intake manifold or the 01 one if so id get the vafc2 to control it if i need it
so use the 3.5 plugs and soldier them on to my 3.0 harness correct?

 

any info would be greatly appreciated thanks

 

anybody please

 

I just got cable internet 2 weeks ago, and i learned all I know so far of 3.5 swaps rocking the 56K, so dont tell me its impossible for you to search around. s0ber, Jclaw and myself did 75% of the research for you with our replies, take it from there

 

I didn't get the information handed to me on a silver platter either. There are plenty of threads around in this forum with MORE than enough information. And if those aren't enough, you can always contact the people that performed the swap via PM and/or AIM like i did. Good luck.

 

hey nismo what up. you doing the 3.5 swap too? is that the secret you had when you sold me the mevi. good choice by the way if you are.

 

ok thanks also with the egr system do i use the 3.5 or the 3.0

 

.................. for asking such thing, ESPECIALLY after we told you there's no excuse for you not to do your own research. Nuff lecturing...

mods please

 

dont turn into a all motor troll like grandpa!

 

The 3.5 engine uses cam timing to control exhaust reversion and has no external egr system like the 3.0 does.

The 3.0 egr valve and egr bpt will bolt onto the cylinder head, but there is no place for the egr guide tube to connect to the intake manifold. I'm working on a way to do that, though, but I won't have anything anytime soon.

 

what fpr did you people use it almost looks stock i think it was nismos pic

 

Any adjustable fpr made for fuel injected systems will work.

 

I bought the Nismo one for 300z from Courtesy Nissan. Pretty decently priced and I wanted to use as many "Nissan" parts as I could.

Also there are probably 3 or 4 good threads about stuff like this. Just look for the ones titled "VQ35 up and running" or "Yet another VQ35 up and running." There is a wealth of info in those.

 

The intake manifold part of this doesnt make a whole lot of sense to me, but stick with the VQ35 stock IM. Its already bolted to the engine for yah. I guess you could use a 00VI, but im not sure anyone had tried it. There might be some weight savings there, though marginal.

 

You have to modify the lower IM to use the 00vi.

 

im just trying to use the whole block of the 3.5 with all the 3.0 stuff ok so im gonna look for like a nismo fpr

 

I think you would be A LOT better off using the heads and IM from the VQ35. All you need to reuse from the VQ30 would be the water pump, timing gears, timing chains, timing guides, timing chain cover, under drive pulley, and the upper and lower oil pans. You might be able to reuse the oil pans from the VQ35, but I didnt. There was some contriversy about this issue and at the time we went with the safe bet.

Also you can sub in a Pathfinder TB for your VQ30 one. You will need an adapter plate which Stephen Max can sell you.

 

You don't need to change out the oil pans. Use both 3.5 oil pans it's much simpler, there are two holes in the 3.5 oil pan for the two 3.0 sensors (forgot which and which) that go on the oil pan.

 

And you can also use the stock 3.5 oil cooler if you also use the 3.5 thermostat.

Edit: This is if you use the 3.0 oil pans

 

This thread has a lot of basic info+useful pics.

 

i got a question couldnt it been a bit easier if we used the 3.o intake manifold and injectors just to get the car done then later on change it?

 

instead of cutting the harness n stuff also should i just get an oovi and get the lower pelnum drilled for it wouldnt it be better off?

 

i was wondering also since the motor isnt in yet is it worth it to get this unorthdox puley

http://cgi.ebay.com/ebaymotors/Unort...95861796QQrdZ1

and also could i use the stock belt

 

i have 1 more question could i get a vafc2 to control
( Get a Summit rpm switch to control VIAS activation)
or get the summit rpm switch

 

im lookin to purchase adapter plates from anybody that has them available
im using my stock 3.5 manifold and stock3.0 throttlebody so i believe i need 4th gen adapter correct and how much for both get back to me thanks

 

Here is a good question for VQ35. I have heard that all 95s are OBDII and then I have heard that extreme early 95s are OBDI. If you were OBDI would the ECU control the VQ35 correctly? I have no idea if I am OBDI or II, but I am a 95 max.

 

I don't think any of the VQ's are OBD-I since it would basically require a redesign of the engine to go from OBD-I to OBD-II. I'm quite sure that the VQ was designed for OBD-II from the get go.

 

Correct, there are no OBDI 95's in captivity. We have heard of one in the wild but no one has seen it yet.

 

Yeah we only have blurry black and white pictures, fabricated footprints, super old and unclear films that may or may not be a guy-in-a-suit with a zipper and sightings from half drunk, half mad guys claiming it ate their buddy.

 

You can use an underdrive pulley, just make sure it has the VQ30 timing ring. The UDP for the VQ35 will cause a crank pos sensor CEL.

You will need a shorter belt.

 

It doesn't matter whether the ecu is OBDI or OBDII, since the sensors that are used by the ecu are transferred to the VQ35.

 

Thanks Stephen Max ... that clarifies everything. Doesn't it suck to be a college student with a low budget and be stuck on a forum where people do engine and tranny swaps. All I can do is druel. I don't want to wait 4 years before I can start doing this stuff.

 

One you start modding, there's just no stopping it. I'm already obsessed and I've been modding for only about 5 months now.

 

i cant get the car to start i checked everything

 

Is it getting gas? Spark? Is it cranking over?

 

its crankin over but not starting and theres no fuel goin through?
