I want a full 3.5 with a '00 VI, '00 Fuel Injectors, and Fuel Rail, full VI lower and upper IM. How would you make this work with a full 3.5 heads, and bottem end???

 

May I ask why not just the complete 3.5?

 

I believe you have to use the 35lower and make hte ports oval to match 00vi.

 

'00 VI flows better, and I don't want to use 3.5 fuel rail because then the car runs lean...

 

and you have proof that the vi flows better than the 3.5 IM?

 

Tilley lost power after 5.5K RPMs and he HAS messed around with different IMs I will personally take YOUR (vsamoylov) opinion with a grain of salt as oppossed to Tilley, if he says that the VI flows better than the 3.5 IM there has to be a legit reason why. Krismax is obviously mating the VI on the 3.5 for a reason, because top end is good as well as low and mid range...

 

they both have a 3.5 in their 4th gen right? or what is left of vq35 right?

 

DUDE WELCOME TO MANY MONTHS AGO! Tilley has had a FULL 3.5 heads and bottemend for quite some time now, Krismax is in the process...

 

no i know that but what i was trying to say that they did the swap but it isnt a full complete 3.5 swap. maybe that is why they are trying to use the VI because not a complete swap.

 

Yeah, I read that in the other post as well. Sorry for the dumb question.

 

might just wanna talk to sr20den and see if you can get one of his IM's instead. That one definitely flows better than a normal de-k IM

 

and everybody that has a 5.5 gen max here wishes to know what he has done with it or at least a dyno graph between a stock 5.5 gen IM and his IM

 

I'm planning on running a full VQ35, and if retrofitting the 00VI isn't TOO hard, i'll go that route. But I have a general idea of how SR20 made his mani.

 

Why would you be so dumb as to use a DE-K manifold on a 3.5, especially is using the whole rest of the motor?
Keep the better designed aluminum manifold.

 

Scroll up. It was mentioned that the 00VI flows better than the 5.5 gen manifold. Tilleys said it flowed better. Krismax has this setup. They sure arent switching to plastic just for weight reduction you know.

 

I thought Tilley was keeping his 02 IM?

BTW, the 00VI has yet to be dynoed on 3.5 heads, so we don't know yet. Tilley dynoed 226whp/205wtq with the 00VI, 3.0 heads and 11.5:1 comp. Then he dynoed 233whp/230wtq with the full 3.5 (better heads and all, but 1.2:1 lower comp). He opened a valve on the 3.5 and dynoed 238whp/223wtq.

Also one of the reason his top end isn't good, I think, is because he doesn't have the 3.5 ECU. Stock VQ35 cams stay a 240 degree lift all the time if they don't vary (in Tilley's case, they don't). But when you have the VTC with the 3.5 ECU, they vary from 205 degrees to 275 degrees. My guess is that this is to get the best of both worlds.

Also, he has a light flywheel, UDP, full exhaust system (with headers) and bypassed AC/PS, so I think he would dyno more, both peak and along the RPM range with the 3.5 ecu.

 

VTC does nothing over 3000 rpms.

 

that is excatly what i am saying. you guys dont even know how the 2k Vi will work on the 3.5. the 2k VI works good o nthe 4th gen maxima because it is the same engine. the 3.5 is a different engine. that is why there is a different IM which was specifically made for that engine. and the 3.5 IM will flow better because it is made for a engine that has a bigger displacement. the 2k Vi was made for a engine with a displacent of 3.0 (not 3.5) ans same goes for the top end and bottom end.

 

The 3.5IM doesn't flow that good after 6K RPMs, The VI has more top end...

 

I would say with the 3.5 max IM nissan was trying hard to have low and mid range ...but with SR design he shifted that but...i cant go to wally world and buy his IM .Can you?? He has good hp but peak is nothing special.
If the max 3.5 IM was so good how come nissan doesnt use it on the sports car 350z?? Because stock for stock the 350z IM is better . My point is its prob not the best IM for the powerband im looking for.

I'am just testing the dek on the 3.5 if its no good for me ill try another IM...obi wan there is another

 

What did you do to make it fit?

 

Lots of aluminum in my eyes

 

sooooo.... modification to the 3.5 lower?

 

so did anybody try to put a IM on a max from the 350z?

 

Emax was the closest to doing that.

 

and did he succeed or what happend?

 

I wouldn't say that. It said it increased torque and horsepower by 9% at 2000 rpm, and by 12% at 3000 rpm. The "increase" certainly doesn't just drop off like a cliff after 3000.

 

Well i dont think he was refurring to grocery power.

 

Increase from what baseline? Opposed to no VTC?

 

Opposed to no VTC. If the only difference between the 3.0 and 3.5 was the .5 increase in displacement, it wouldn't make the power it has.

 

Tilley dynoed 230ish w/o VTC right? that seems about right.

 

He has UPD, headers, exhaust system, lightweight aluminum flywheel... I was expecting something in the 240's.

Also, those are peak numbers. He hasn't posted his graph. No doubt his car must pull real hard, but it'd be interesting to compare graphs.

 

BTW i ditched the flywheel it couldnt take my abuse. 2nd gear burnouts took its toll on it.

 

I see I made a good choice to keep the OEM 18-pound unit. Did you dyno with or without the flywheel? Removed it after?

 

238# is with stock heavy flywheel.
