That post was entertainingly ironic. Glad to know your all the same color here. (figure of speech)

I was doing a little searching on Google for info on the Isuzu v6 and stumbled across this forum. After reading every single page, I had to sign up to comment on this.

Dear OP please consider that your project will cost more then you anticipate. The Isuzu engine has no tuning support and you will have to run a stand alone. You could risk a piggy back on the ecu of whatever Isuzu you decide to pull the engine from but youre talking about new manifolds and cams, I wouldn't trust a piggyback to handle the job. These engines burn oil, rebuild it with the drilled pistons and pray, your rebuild will cost more with these pistons. I own an 01 VX only 60,000 miles and I check my oil every fill up.
Now if none of this turns you off and you have no value for the time you'll be spending setting this up then go ahead otherwise, maybe try the eclipse and do a rwd swap or just get a 350z.
I'd love to see this happen but have nothing but doubts, you'd probably find better answers on an Isuzu forum, Isuzu planet or vehicross info are good ones.

Why were you researching the Isuzu engine?

I do value the time spent. I enjoy it. The only piggyback I've worked with is the FIC and it worked quite well. Many people get squeamish when the think "custom fabrication=$$$" but it's really not a big deal. I'll probably have more frustration with the steering rack and wiring then anything else but there's always the accomplishment to look forward too. What do you mean by tuning support? Aftermarket parts support? The tuning itself should only be done by someone who understands what they're actually doing and why. They should not make changes based solely on what others are doing. The engine will start off NA using the Isuzu ECU. The only tuning I may have to worry about is a shift in VE due to the manifold changes. The factory trims may be able to account for it, or not. If it's too far off I'll piggyback it.

It shouldn't be that expensive as far as cash is concerned. The metal plate and tubing for fabricated components is free. Selling off the RX8's parts will cover the majority of Isuzu components. I'll have a lot of wire and hose to buy but that's a small percentage of the total cost. I've done many projects and understand things add up quick but a large portion of the cost is offset by the value of the components that are being removed.

As far as Isuzu's "problems". Consider what it is, Isuzu. I can't imaging people taking great care of them. If they all had oil burning problems due to an apparent design flaw, they would all be smoking. I can't think of any time I've been driving around and thinking "there's another Trooper smoking away". I have seen my share of Mitsubishi v6s smoking away and thinking that, about Mitsubishi. They had a valve seal problem on the 3.0L v6 where at >100k they begin burning oil. Or Mazda's rotary eating apex seals by 70k (customers aren't always to blame). Or Subaru's gobbling up timing belts before 100k. Dare I mention the GM DOHC 3.4L? THAT was a disaster but many of them are still on the road. Many motors have one quirk or another. I think owner neglect does more damage to engines then the designers do. I'm not expecting 200k out of my Isuzu engine. I'm happy if I get 50k. I'm sure to sell the car in 5 years anyways. That seems to be my average car project cycle.

now your just not listening lol. i have an isuzu vehicross, 3.5 v6. only 66000 miles and i check my oil at every fuel up, this is the way of an isuzu owner. they rarely burn enough to visibly change the exhaust color but it happens. do a little more research. you will have to piggy back the ecu for sure, but once again im going to recommend doing some more research and getting a standalone. My grad gift to myself in 3 years will be an lc3 northstar, 4l60e and holley dominator, the difference between our planning is i know how I will be operating and tuning an engine and transmission. Maybe take 2 seconds trying to locate a single aftermarket part for the isuzu engine, its all going to be custom for a reason. you keep mentioning lighting it up on a roll, well goodluck with that, you mention changing your gear ratio, thats great make it accelerate better, lose some gas mileage and put the engine rpm higher for long drives, these engines burn more oil on the highway then in the city. once again if you want real answers ask people that own it.

Awesome.

I really would love seeing a v6 application in an rx8 just really really worried about the disapointment in an Isuzu engine at the end of a day. Its a pain in the butt. And if it does happen I'd love to see it but is just feel so bad for the owner. If your going through all that effort to make it crazy, just consider a different engine is all I'm trying to say. Ifiit was me id run a 4g63t, there's even a site dedicated to setting it up in rwd applications. Use a transmission without much for electronics and away you go. Eprom/socketed dsm ecus are tuneable on speed density no need for piggybacks or standalones. Oh well. I'm not trying to start a war just don't want to see anyone go through that and deal with this engine. Ill upload a highway pull in my suv shortly for you guys to laugh about.

let me know if the link doesnt work, sorry for the slow intro lol.

godesshunter

What happened at the 2nd gear change at 4400 rpm? Did you let off or did the engine hesitate?

ABdragonVX

I do believe its vtec kicking in haha. Every gear 4400 quick stint just like you see and then a different tone and a little more kick then under 4400. So to answer it wasn't me haha

Holy slow. Sounds pretty good though.

An engine swap for that? Could at least do an LSX....

ABdragonVX

my isuzu is also heavier, automatic, and all wheel drive......it would do better with less load

Just out of curiosity. What would izuzu owners know about how much oil a rotory uses? And how often do you see a vehicross?

I believe he is talking abut the izuzu motors burning oil...

Paco664

to the OP... i hope you finally get going on the build... i understand how having the ability to fabricate and having the machinery to do it makes things A LOT cheaper....

i am new here and really don't wanna toss rocks into someone else's pool but let me say that i have read every post in this thread *(slow day at work) and i am appalled at the disrespect and general tone of nastiness...

i wouldn't care if he was planning on swapping in a aircooled VW motor and transaxle...

he apparently has performed unusual swaps before... as have i.. *(1973 ford courier with a mustang 5.0 with c4 transmission.... 1970 datsun pickup with a 1979 mustang v6 and 5speed..)

anyway.... best of luck... start the swap soon and take lots of photos...

ABdragonVX

i dont know anything about your rotaries. im warning against using the v6 isuzu engine, its damn near the same between the vehicross, rodeo, and trooper. im all for a v6 rx8, just hoping to help the op pick a better engine.

and once again i see a vehicross daily, i own it. pain in the *** checking and topping up oil all the time.

if you read everything youd know the op was looking for advice and input, im just trying to get him to steer clear of the isuzu engine.

Paco664

I understand that... My comments were not aimed at you...

I used to own a Isuzu rodeo with a v6... It was underwhelming to say the least...

But in the OP's defense.. He is choosing this engine because they are cheap plentiful and gives him a buttload of transmission options...

Me personally... I would ls6 it... But.. It's his car...

I wish him the best and will follow his progress or lack there of...

ABdragonVX

sorry just spitballing answers.
he did mention one goal being the added power, just hope he considers that a little closer. im also wondering how the ecu will handle the lacking presence of the variable intake manifold.

Mr_Pieper

The OP got a bunch of crap because he was trying to be cheap with a car that doesn't accept cheap well. He then came around with his hands out waiting for someone to spoon a bunch of answers into his mouth. Then his swap was the answer to all the problems of being an 8 owner. Then he fought with people. Then he went the route of taking his toys and going home. All of this with nothing to actually show for it. This thread is still in the "Major Horsepower Upgrades" area and I have seen nothing of the sort. This swap was supposed to be the "answer" to all of our delusional rotary problems and it has become a joke that has permeated most of the site.

kickerfox

I think a lot of people here feel I'm "polluting" a "fine sports car" with "Isuzu garbage". To each their own. To me it's just a RWD import with fairly decent handling, decent looks and comfort, and a large engine bay (compared to other imports). There's nothing "magical" about the car other then it having a unique engine.

I'm not creating some RX8 cure-all v6 swap that suits everyone's tastes so lets get that straight. The Isuzu engine was chosen for many reasons which I've clearly stated. Transmission options being the number one reason, availability and cost is second. I will be keeping the factory ECU for emission testing so I chose an OBD2 vehicle. Aftermarkets parts ARE available IF you know how to search. Ever hear of interchange? It's much less costly to modify an aftermarket part (like a Supra rod) from another application then it is to have custom components made.

The "this swap is stupid" comments are not necessary. Comments such as "this is not a wise swap because ________" are. What's the point in turning a discussion into an argument?

The note about the oil consumption was known. The Isuzu engine lugging in front of an automatic in a 4000lb+ 4x4 doesn't help the problem either. An engine is an engine to me. The similarities are plenty and the features that make one engine better then another are present in the Isuzu v6 so don't burn it at the cross just yet. The Aussies put these engines through hell.

I'm here for fun and to share my ideas and plans. Everyone is welcome to their opinions and I can take constructive criticism IF there's some backing facts, such as oil burning. I can find data to back that. Just saying "it's stupid" doesn't accomplish anything.

First thing is to get the ****** out of the engine bay and sold off so I have room to work. When you start seeing parts forsale I'm getting close. =)

ABdragon, you mentioned "make it accelerate better, lose some gas mileage and put the engine rpm higher for long drives". If you check the plots (graphs! :P ) you'd see the lower gears are close to 8's stock gears but the higher gears are higher then the 8's stock gears. I should be cruising around 2800rpm but with a little more trans research I hope to find something with a wider gearset. There's an overdrive gear available that I believe was .68 but I forgot what that was in. That's the whole point of all the graphs and math everyone is so eager to insult. The real builders know exactly what I'm doing. I'll even calculate the exhaust note of the shifts just to see what scale their on. =)

when are you planning to start turning the wrenches??
