My friend is trying to convert his 99 manual SE to a 4.0, 3.5 atleast. It's going to be his project for the summer as he says. I was wondering if anyone has actually done this or heard of such a thing. Wouldn't it just be cheaper to buy a 6th gen engine and drop it in there?

 

The best thing he can do is to sell his car and buy a 2002+ Maxima.

 

That's what I told him to do, but he hates the 6th gen look but loves the engine and he has always been big on his 4th gen thats why he wants to keep it.

 

4.0? I don't see how you could make a 3.0 into a 4.0, or even a 3.5. The most that I'd think you could get out of bore and stroking even would be 3.2 (MAYBE 3.3) but the costs of doing that would not give you the performance you would expect for spending that amount of money.

 

just drop it in or slap it on....either will work.

 

It's mad easy to do yo.

 

yo it's really easy to do actually...

last week i finished converting my 3.0... it took alot of hard work, but now it's a wicked 5.4. Thing is a highway beast now!!

now if this were feasible... that would be pretty interesting to see... but uhm yeah... i was messing around... In all actuallity i think someone had tried this here a while back? they only got it to like 3.1 i think it was? not sure... But like everyone else is saying. It's not worth it.

 

does someone make pistons, rods, and rings for us to bore and stroke the engine??? news to me.

 

I don't know about you guys but I dropped a 350 crate engine into my Max a couple of years ago. It took me like a couple of days and while I was doing that, I converted it into RWD. It's a lot easier than you think.

 

yea and i have 2 LT1s

one for the front wheels and one in the trunk for the rears

AWD yo!

 

I'm sure for the right money a shop can customize that for you. I don't think anyone has done that and for good reason I'm sure... $$$

 

350 ? that s a lot of bull...I d like to see that...Boy,someone is luck is not Pinocchio...
I agree that you can probably make a 3.2 or 3.3,but probably is not worth the investment.

 

The 350 crate motor comment was dripping with sarcasm...

 

i will put a V12 6.0 from a S600 next week, i just have to glue the plastic motor part on the other scale model jejejejej man..!! 4.0 on our max???

 

Dude, that post was laced with so much sarcasm if you snorted it you would probably drop dead.

 

just another case of someone running their mouth without doing their research......

Realistically, look at the FAQs and get your facts straight. People have been trying to get more displacement out of the 4th gen since they came out. Between trying to drop a VQ35DE in there, trying to fit a skyline engine in it (not displacement but TT capability), etc, etc......

And sure, custom rods and pistons are feasible, but look at the price that JWT charges for Cams ($1000+). How much do you think a shop would charge for custom fabrication? Plus, the labor involved with installation.

On the other hand though, i want to encourage your friend to follow through with his plans. the odds may be against him, but at least he's doing something new and unique.

 

Some people just can't get a joke now, can they?

 

maybe he should try AOL 8.0 ?

 

i mounted the 4.0 engine in the trunk and kept the 3.0 in the front. now i got 7.0 and 4wd.. mad fuking easy yo

 

 

I can't believe noone knows anything about the internal properties of the Maxima engine. Has anyone on this list every rebuilt one of these engines or is it all wings, air filters, and bolt-on exhausts? Do the technical people skip threads like this? Are there technical people?

 

we know about the maxima engine internals. it includes some cams, a crankshaft, a few pistons, connecting rods, that sort of ****. I think the point that everyone is trying to get across is that there is not alot of aftermarket support for increasing the bore/stroke of the VQ30.

 

I'm skipping this one for my sanity

 

Maybe I should mount my wing on here...



Or maybe in here...

 

Or here:

Or here:

Okay the last one is a bad example.

 

thank god the "technical people" are here

 

I'll have a 3.5 in my 98 by next spring

 

man ive been telling him not to go through with it because he will put so much money in it and it won't be worth it, thats y i posted the forum so you guys can help me convince him not to go with it but...... he says he will and when he accomplishes it he says, than its over.

 

Hello? Turbo? I love the 4th gen, too, but the mad work involved with uppping the displacement, that's ALOT of work.

DW

 

Not mine, my buddy Ferhan's:







Someone just got

 

what is that? heads, cams and rods? what does that have to do with displacement? how do we know those are not stock?

 

stf u fools grow up, maybe he will actually do this and we will all benifit from it by him telling us the steps to get there, ever wonder why we dont have displacment kits? because the ideas of doing more than bolt on get shut down my ignorant fools, some of you guys are so cheap you dont even use premium fuel. why isnt there a maxima that has this done to it yet? i find it really odd when tons of other cars w/ less potentil than ours have it done. so my final word is .... try something new, go build your own part, maybe youll pave the way for people who dont have the you know wat to do it themselves, maybe ull actually puit ure part into production and make money, who knows maybe u'll fail, but hey, what have you lost in the long run? a little bit of money? life goes on

 

Waveridr is right, after thinking about it some more, I mean sure it might seem like its a "waste" of whatever (time / money) but if we don't expirement with our cars we will go no where, look at the honda guys, they're alway accepting new ideas and when someone around here gets a new idea, we shut him down, including me, I also told him to forget it but now I will join him on this lil project.

 

I'm still wondering why the ORG has never tried to get in touch with the people that actually designed the MAX. If we got a chat or something set up with the enginers that made our cars, who knows what might happen. They should know better than anyone else about the weaknesses of the engine, and what can be done or undone to get more power...

 

If my info is correct, Nissan did make a VQ30DE engine with a variable intake and an added feature of variable cam phasing. It was produced specifically for the Japanese market. It is rated at 250 horsepower.

 

well, theres a start..... feild trip to japan junkyards! why doesnt someone order these parts from japan and do the conversion?

 

Why don't you quit telling people what to do and do it yourself.

 

im doing all i can, im dropping $700 plus in about three hours for parts

 

 

It is real gay when people always talk about my friend is... blah blah blah to their car let him/her post about it. When people say "my Friend" it is an immediate disclaimer. In other words they don't know ****!
