Roman's 4GR V6 Carina discussion thread

[fuel]

you would think being an alu motor that the bore size difference wouldn't account for that much extra weight - maybe it's the difference in DI cylinder heads or something like that. Dual VVTi vs single VVTi? who knows

If I can fit a 1uz in a corolla without modifying the firewall or ditching the swaybar, you can make this work. 
 

Rear sump is the current headache.
The sump cant get past the steering column. So, I dropped the rack down.
Cant get past engine mounts. so chopped those off.
Cant sit far enough back so chopped part of the firewall so one of the banks could sit further back.
The bellhousing hits the tunnel before the motor is far enough back to drop down past the steering rack.
Even when I dropped the crossmember and rack, I still cant get it to fit. "
I tried the Hyperblade trick of flipping the crossmember around, but the bolts for the crossmember arent on the centreline of the lower arms, so it doesnt work.
It might work if I chop some of the tunnel out, where it's hitting the gearbox.
But its not going to be an easy motor to get in and out.
If I do persist with chopping more stuff out, it does look like it will sit fairly decently low and fair back though. Good room for intake activites.
Exhaust manifolds should have plenty of room, dont think the steering column will make life too difficult.

But that's enough for one day.

That looks ok where it is, just start connecting shit up pls.

[Honda Ass Dragger]

J35 is the answer

 

[VitesseEFI]

Ah…. Challenges.  Big challenges.
 

Old fashioned pushrod V6s and V8s are amazingly compact.  Modern DOHC multi-valve ones though are mostly very bulky at the top-end. Winged sumps are a PITA…..

You can also look to go remote oil filter, probably worth adding an oil cooler as well. 

 

Is the oil filter built into the sump? 

 

Front/custom sump maybe the way to go. Could you 3d print a sump and then get sheet metal etc to weld one up?

is this one different from yours? 

 

Actually how different is the bolt pattern on the sump if you wanted to run it backwards, (could always modify the pickup)

 

Modify or use and adapter to run the sump as a front instead of a rear?

woah dry sump 10,000rpm 2.5 v6 i like it

[~Slideways~]

I like this, jumping right in there firewall cutting and all.

I've never driven the 2.5 but the 3.5 is such a good engine, always surprises me how it can haul a reasonably big car along. What does an '08 GS350 weigh?

Googles...apparently 1700kg-ish! Man, remove about 800 of those and you're onto a winner!

So will make some engine mounts, get it in the right place then start drawing up a sump. 

What filament are you gonna print the sump with? Carbon moooshed overtop of it?

I feel like they fucked up with that ebay listing, that sump looks identical to Dave's one.

 

I've been toying with making an adapter for my 1uz to run one of these SR20 pans https://www.trademe.co.nz/a/motors/car-parts-accessories/performance/other/listing/3995918987

I love how quick this is moving along at!

Yeah think the ebay listing is wrong. Also don't BMW use plastic sumps 

[Spencer]

Man pretty decent sized donk these things. The big boy 3500 with throttles and 300+hp would be pretty sweet NA if you want more beans later.

Anyway I don't know shit about them but went briefly looking, this dude jammed one into a mx83 which in the scheme of things is similar to the Carina. His IS350 engine looks to have a real deal front sump but I could not find the corresponding front sump in parts diagrams and gave up. Can probably dig it up and buy one new the mid sump one on Amayama is like $300 for the alloy part.

[Spencer]

OK he says in that thread somewhere the front sump is FWD, seems like theres a couple FWD sumps one is front and one kinda blobs into the middle. Anyway find the sump he has.

[Roman]

Yeah the difference though is that a 4GR is a $650 engine and a 2GR is a $4000 engine as best I can tell. 

I've got a scheme for the sump. Should be sweet. 

[xsspeed]

are you on holiday or something, no spiders getting any action

[Roman]

Yes I've got a fire lit under my arse right now.
Starting this time next month I've got double mortgage to pay, which is going to mean 2 min noodle spec life budget until my other house sells.
And heaps to do to move house and tidy up old place.
When I move house, I'll have no garage anymore until a new one gets built.
So this needs to go into storage where I'm not sure if I'll have any meaningful access or ability to make any progress.
So if I can at least get the engine mounted and confirm that there are no deal breaker issues. 
Then for my time with no shed / car access, I can at least carry on scheming and saving for some parts etc with the end goal in mind. 
Also I can work on some of the "free" stuff using materials I've already got. Like wiring it up. 
I've only got a few weeks to get as much done as possible to mount the motor and decide if it's staying in the car.
No motivation like a deadline, right? 

Mounts are in progress but I'll probably need to try get this finished next week.

Whats the sump plan secret guy? alloy sumps with bracing make sump changes annoying compared to the old tin sump cut and shut stuff.
