Any thoughts or ideas for swapping the standard 95-99 3.0 V6 with a new 3.5 V6 out of the 2003 Max? I am currently swapping two CRX motors right now.. I bet Shing would be up to it!! Just your thoughts.. I'm sure that ecu and motor should fit.. It appears that the motor mounts and tranny mounts are in the same general area.. Just a thought.

 

wont work.. try the 227 hp AE motor first

 

yuh

well, it might work... if someone can confirm if the bare 3.5 shortblock is basically a bore and stroked version of the 3.0 (not an entirely new block). it might work.

honda guys have been swapping crv shortblocks into their integra ls (non vtec) or hybrid civics (civics with integra motors) and using the crv shortblock as their foundation for a motor buildup because it is basically an ls block with bored out cylinders. everything else from the smaller ls non vtec motor (head + intake manifold, exhaust manifold, engine mounts and tranny, etc) bolts right on to that block to install in the civic or integra.


this is all speculation but it may lead you to the right direction. assuming that the 3.5 and 3.0 shortblocks are similar on the outside (tranny bolt pattern is the same, etc etc) you should be able to use the 3.5 longblock and reuse your intake manifold, exhaust manifold, engine mounts and tranny. if someone has access to a wrecked 2k2 max it would be worth a shot.

 

My thoughts are on a 3.5L short block with 3.0L heads, fuel sys, electronics and sensors. This would would be the way to go for a relativly inexpensive upgrade. You will need to check the motor math to be sure the compression ratio works out using the 3.5L stroke, bore and pistons with the 3.0L head cc. If its off, custom pistons would only be a few hundred dollars.

 

actually, that's what i was thinking. about the different compression... if it wasn't something insane, then why not keep it the way it would be? higher compression would just be a way to get some better power without boost, and of course, lower compression would just be making it safer to add extra boost onto it.

 

..how many times must I be reminded. Ya it would be 2 good 2 be tru. It hopefully will become reality, but as of now stop tryin to be a vintage. Get a V2. (or cough up the dough and answer the Q's)

Sure U can do it.

 

Yea, just supercharge it. You will be alot faster than if you transplanted the engine, and you'd have that awesome wine of a s/c that leaves people in awe.

 

GET a super charger, twin turbo, 9550 shot of NOS, four turbine engines. Oh yeah and some rocket boosters. You'll hit 11's no problem. Hey, take it from me. I've been doing this sorta stuff for years. After that your Maxima should be pretty peppy. Tell me how it works out. One last thing Mod boy. You're def. gonna need Premium fuel w\ these up grades, don't forget that. peace

 

chill holmes...

 

I think it'll be cheaper to buy a new Altima with the new engine. And that will only weigh about the same as your max. The added weight of newer generations almost always correlates witha stiffer chassis. The stiffer chassis would be needed, especially in the turns where we drive fast most often. The limited slip and 6 spd tranny probably add at least as much as the torquier engine.

 

i could do without the holmes .

 

If someone makes this happen I would love to see how. Man the power of the 3.5 in our cars would be sweet since we are so much lighter.

just a thought or two.. has anyone on this board even have a custom piston/rod setup? we're talking about engine swaps and all, and i don't think we've even done any internal swaps. also, considering that some people are looking into the auto-to-manual swap, anyone have any guess as to if the 6-speed would bolt up?

 

Done yet?

 

Hahaha... bringing up old threads, I LOVE IT.

 

it bolts up, it fits, but it doesnt work, is what ive heard, number 1 reason, Cable shifter.

 

My SR20 swap into a 87 maxima would have better results .

 

At one time, someone mentioned dropping a crank and connecting rods from a VQ35 into the VQ30. Because they are supposedly the same block, this would effecively stroke the engine to 3.3 liters. I would figure a large increase in torque. You'd have to watch out for an increased compression ratio, though.

 

didnt we have this exact same thread just two days ago? and two days before that, and two days...... but for some reason people are actually being helpful in this thread. i guess because the guy asked the question reasonably.

 

You missed the point... look at the dates on this thread and the other ones.
