3.5 Swap
 

I can't seem to find the useful threads on this topic. Honestly, I don't know if this have even been done. Is the 3.5 a direct PnP swap, provided you swap the ECU? I have a 2004 5AT. I'm not talking swapping internals to make a 3.5, I'm talking a complete block (eg. entire motor/engine) swap. Would I need an 07-08 guauge cluster, or would my existing one work? Thanks.

you would need the ecu, looked into it already, when I blew my motor

That's it, just the motor and ECU? Any reason why you didn't do it?

This is interesting, keep it going...

EDIT: I found some 3.5L engines for under $2400 and under 15K, is that a good price?

motor tranny and ecu...

Ah, tranny, too. I didn't think the 5AT changed over the course of the 3G. Oh well, that answers that. A new 3.2 it is.

Thanks.

^^^blew ur motor? if so how?

Won't work buddy, tranny won't line up to the block. why not just swap internals?

The water I thought wasn't that deep was that deep :tomato:...well, deep enough.

Well, if the dealer just wants to swap internals to fix it, I might, but I think they're just going to pull and swap the block. I'm supposed to find out later this afternoon.

Sorry to hear man.. was this cuz of a CAI? And is the dealer good willing it or its out of pocket for you?

sucks.. sorry to hear this. I am dealing with a new motor and 5k break in period and it sucks. Keep getting a po175 bank 2 running rich code.

Oh yeah, CAI. Damn thing wasn't completely submerged, either. I watched a Civic drive right by me as I sat in the water :whyme:.

Good will? Why would they do that? Warranty ran out a year ago (4 years, I only have 36k miles), but even so, it's my fault because of the CAI. If a miracle doesn't occur (they dry it out and start it :pofl: :pofl: :pofl: ), I'll most likely file against my comprehensive and just pay my deductible.

Sounds like you have my luck. That's the kind of thing that would happen to me...new engine, but somehow it has problems. I've got a 2009 TL until it's fixed :shrug:...it looks great from the inside :rolleyes:.

dealer swapping internals? huh :what:?? they're going to order you a short block and gaskets and do a straight swap. even if they replace it with another j32 they're not going to build it. so if you're going thru your insurance, get the $$ and have the block built. i think a NEW shortblock is around $1100+$300(gaskets)+labor will put you right around $2k. For ~ $500 - 1K more (depending on the parts you use) you could go to a 3.5, just my :2cents:

The rain here lately has been crazy. I am sorry to here that that happened to you. If I get a V2 then I might make a cover out of fiberglass to surround and shield the filter inside the bumper. It's not that hard of a thing to do. I'll make one for you if it works out and seems like a good idea.

I never thought about water damage from CAI, you know always thinking I'd never drive through a lake but the heavy ass rain in Charlotte has definitely changed my perspective on that!

Yeah, that's what I figured they'd do...couldn't see them swapping internals. Unfortunately, I have other uses for my money that are more important to me at the moment, so I'll be going for the cheapest route; deductible plus another $500-$1k isn't it. I was only going to do a 3.5 if I could just swap the blocks since I figured that's what the dealer would be doing. My thinking was if you have to get a new block, might as well get the better one...assuming it was PnP. I would've sprung for a new ECU, but I'm not springing for a new ECU and tranny.

I appreciate it, but I won't need it. I learned my lesson. I should've known better this time, but stupidly thought I was ok. I won't be in this situation again. I've driven in the rain for years with a CAI with no problems...it's fording rivers that causes problems.

There's nothing to worry about, just don't drive through lakes/rivers. Hell, I've even said that to people before. So what do I do? I drive through the lake. I thought about it and deemed it safe; it wasn't. My new rule: if I have to think about it, it's not safe.

Sounds like a good rule :thumbsup:

did it stall or did you cut the engine immediately?

It stalled, but I was idling through - no gas pedal...suction was minimal and the water wasn't deep enough to submerge the filter.

UPDATE: The dealer just called. It's running :what:. They pulled the plugs, cleaned the intake, got the water out, and it's fine. They're changing the oil (has water in it), but it was due for an oil change anyway. $144 for the cleaning, $50 for the oil change, and I get my car back within the hour (about to leave to go get it). Everything considered, I'll happily take my $265 ($65 for the tow) lesson learned.

That's really good news. My buddy locked his civic engine but he was driving around in water up to his hood and kept cranking it when it stalled.

I agree.

That is good news. I am happy for you. So does that mean you're not swapping a 3.5?

No 3.5. It was only a consideration if it was PnP and I needed a new block. Despite the fact that I'm keeping this car for another four to five years, I'm done dropping money on it outside of maintenance; I've already moved on in my mind.



The car seems to run alright. I'll know better tomorrow when I can drive it for real and not in bumper-to-bumper traffic. I hear no funny noises; it runs smoothly and sounds normal.

If I were doing this I'd use the 03 honda odessey motor, with cl-s ecu and tl 2nd gen wiring harness, why? Because then you could tune the motor

Then you'd rock the 09 tl awd intake manifold with an aem v2 cai

Haha.. A+ on that new rule. :thumbsup: How much did it all end up costing you or your insurance company?

Great to hear the car is running. Do you know how deep the water actually was? Like you, I've run cai's for a long time with no issues. But obviously hearing this happen to somebody that, I'm assuming, is conscious about these things is a little unnerving.

if its running have them do a leak down test. MAKE THEM. This will confirm that there isn't a compression issue, that way you wont be back into the dealer a month later with a spun bearing, misfire, or other issue... Cover your ass.

See post 23.


No idea. The fire department unclogged a drain just off of the road after pushing me out. It was clear by the time the tow truck came. Trust me, you have nothing to worry about; this was just a serious lapse of judgement on my part...I doubt anyone else who "is conscious about these things" would do what I did. So why did I? I wish I knew.

2250 for shortblock alone with gaskets and install, got all receipts from new motor install.

somebody did their homework :toocool:

That an I just shared my upcoming plans hahahaha, minus the aem v2

Dude that's such a bummer :(

The rain here in NC has been on and off like hell recently.

good to hear you are back up and running! :thumbsup:

Agreed. Compression test at a minimum as this will show a bent rod.

Too many times these things seem to run ok and then spit a rod out the side of the block.

chilly glad to hear that you don't have major damage. :thumbsup:

chill_dog is the master thread jacker. :tongue:

:tomato::tomato::tomato: j/p.

so is the definitive answer yes or no to be able to drop a J35a8 (3g type s) into a base model TL-P? (with the associated ecu and tranny of course).

if so, may have to hunt down the whole manual tranny set up and gauge cluster if the redline's different.

i'm familiar with motor swaps, i'd just like to know what problems other people have run into attempting or completing this particular swap.

some of the programming i know has been changed to better suit the cluster for the type s, and im pretty sure a few wires have been added....im sure with a bunch of pin relocations (a shit ton of hours) on the ecu harness and gauge cluster harness it would work.
