largest v8 in a mk2

[SR4410]

anyone know of the biggest v8 possible of swapping into a mk2? maybe a 460 ford or 454 chevy? ahah any input would be nice

i dont think they would fit if you look at the pick of my 302 swap it was a close fit for that evin a 1UZ is a tight fit. they do go in and do look good whin dun.

Big Block just flat isn't going to fit, unless you decide to tube frame the bitch, and the sheet metal is only a shell.

I've seen all 3 of the main players, small blocks in these cars. They can all be made to work.

Not sure how B.C. Aircare would like it either ;)

not all of BC has aircare iirc, so thats not too hard to get around.

[SR4410]

maybe 406 or 383 sbc is a smarter idea. anyone gimme a hint on how to change sump positions and which oil pan to use? and if im correct 351w is front sump.. just something about ford (unless it has huge displacement) pushes me towards chevy.:sarcasm:

[moonpie33]

yes i have a 351 modified 400 front sump baby

as for aircare meh i still got awhile that i can insure the car... but my project is ready for a power plant... and i need to planout the tranny diff/driveshaft and engine so i can get this beast on the road again =)

what kind of transmission drive shaft and differential did u use? and what mods did it take to stick em in there

oooo im sorry it is in a 4x4 81 ranger with the auto trans it is quite the power house

i dont know if that would fit eather a 351m/400 is a clevland block and is bigger than a 302 or 351w.

[williamb82]

if you want a big block engine, why not a early 70's 500 caddy? its already front sump. good luck getting it in there though. that bitch is wide.

[Supra_devil]

just do a chev gen3/4. front sump setup from a GTO will make it work very easy. just check out this http://forums.celicasupra.com/showthread.php?t=29684

not a big block, but it will make a shit load of power with simple bolt ons.

[pituala]

I've actually measured when my motor was out and our 502 was sitting next to my car, and YES a big block would fit. It would definately require some work but the space is DEFINATELY there. The problem I see with the big block is the weight. They are fricken HEAVY!!!!!! The car would handle like shit IMO....not to mention the "snapping of parts" power a big block would make.

[williamb82]

the 502 aint as good as the early 500's though. the 502 was a smog motor. either way yeah, heavy as fuck.

with the kined of mony it would cost to buy and fix that engine you mise as well shoot your self in the foot. we sold our vet just cus of that chevy may be a easy insta power but they leack alot and if it is in the lt or ls famaly it cast a shit lode to fix.

[Supra_devil]

LT is gen 2, i'm talking LS series mainly, or LQ if you go iron block. they can be had cheap if you go for an iron block truck motor. expensive to fix, depends, but the beauty of them is that they are fairly new and overbuilt so unless your trying to make massive power or you drive the piss out of it, you shouldn't have to fix anything. for a mk2 you could drop in a stock motor and have more than enough power.

biggest reason i like em is weight, aluminum block so the weight won't be any heavier than a stock 5m, and you can get a t56 as well which will return great highway mileage.

[SR4410]

hmm well im gonna go to see the 460 this weekend. its a pretty good deal so far like the amount of work done on it alrdy.. its been machined .030 over crank's been ground down, new rods,pistons,bearings and its supposed to have low mileage as well. i also see a 8.8" ford rear end selling and that shud prolly hold the power nice. Anyone know any ford trannys(manual) that bolt to a 460?

ok mn i am a ford guy but hears the problem with a 460, one they like to wear out valve seals they cant handle much over 6000 rpm's unless built right and cast alot more to mod than a 302 or 351w or c. not to mention that they weigh alot ( http://www.fordcobraengines.com/engine_weights.htm ), and you can build just as much power out of a small block. if you could get a true 351c it can handle more power and a higher rpm range than a 302/351w, but agin it is your car and it is up to you what to do with it i just dont recamend a big block. if your going to go to that much truble you might as well get a ford 4.6 v8 or a toyota 1UZFE. hell i will sell you a good running 4.6 for $850 and that inclueds the whole car with everything there needed to do the swap.i am not much of a chevy guy but it would be better and more fesable to go with a small block ford or chevy, cheeper too in the long run.

thanks for the info man. My first choice was a 350 chevy cause i have enuff$$$ to build up the bottom end and make it a 383.. but that 460 is such a steal.. your right though extra 200 pounds of engine + gutted the back of my car. which fucks the weight distribution even more.

there was a guy that did it. wont share the secret. i have an idea on how to do it but never tried it. requires welding. what i would do is cut hte pane and flip the sump up front and reweld, then drill a hole in the side and weld a an fitting, like 8an to the pickup and weld a bracket to the screen. weld the bracket to fix the pickup the proper depth from the pan.

then weld an 8an bulkhead tothe pan i nthe front. run a 8an ss line from the pickup to the bulkhead inside the pan.

weld another bulkhead to the rear of the pan on the side as well and weld an 8an fitting or tap for a 8an fitting on the pump. connect the pump to the 8an bulkhead at the rear on the inside when you bolt the pan on. then run a 8an line to connect the 2 bulkheads.

its harder to explain when i cant just point it out to you in person but im pretty positive it would work. maybe one day ill do this with a stock pan on my buddies 350 he has on the stand and take pics for a writeup then sell the prototype to someone here.

btw, im not keen on chevy oil pickup sizes. might be best ot use 10an. idk.

[williamb82]

true trac lsd and forged 4.10 gears. all new toyota bearings. should hold all that and more. russ was putting over 700hp through a trd lsd and unspecified gears. prolly forged is my guess. he was very secrative.

[83mkII]

lol that is alot of work just for the oilpan, i will do some checking and see what i can fined out about makeing a chevy a front sump. i got some buddys of mine that like to do things like that. and god luck on the swap man i am glad i did mine it is a blast to drive, whin i get to drive it lol. i also agree that the toyota rear should hold up if built right.

[williamb82]

that isnt much work. should be able to do it in a couple hours max. thats easy for a swap that will yield that much more power in my opinion.

what about a 8.8" ford diff? and wat does that fancy setup run for?

[williamb82]

idk, the lsd and gears are prolly cheaper then the mk2, but then you have to fab the rear to hold the irs 8.8 diff and custom axels or fab the rear if your using a solid axel 8.8. lot of work either way.

yeah true that is a good point.lol

i can get a ford 8.8 for about $75 and that is with 3.50 gears and lsd. but it would take alot to get it in the car besides the indapendant rear in the car now will handle better and can be built to handle more power. the ford 8.8 likes to let the axle toobs seperate from the housing after a sertin amount of hp/tq. you have to weld the toobs to the housing to prevent this. ford did make a 8" that is like the 9" and uses the same axle shafts and spiders, but they are in early modle cars like the 60's mustange. but agin alot of work to get it into the supra.

Considering that motor makes the 1UZ look thin and narrow, No thanks. It would be a blast to drive but just too big.

for reference this is a side by side of the Ford 4.6 Mod motor and the SBF,

DAMN!

[Jkm3141]

The problem with the Mod motors is they have a dual cam gear style setup on the DOHC cams, which then makes the heads and timing gear covers very wide. This is also true for the 5.7L 3UR-FE Tundra motor. The 1/2/3UZ motors all have a single cam gear with a spider gear setup driving both cams inside the head (hence the bulge on the valve cover). This is the preferred setup for a smaller DOHC V8.

http://img88.imageshack.us/img88/9005/tundra57l013cj8.jpg

The 3UR-FE Tundra motor. Very similar dimensions to the 4.6 Modular Ford motor. Similar power outputs, though no supercharger

1UZ-FE vs a 327 SBC. Agian a huge difference but not as much as that Modular Ford vs SBF

All well I would assume the width dimensions on the N/A 4.6 DOHC cobra motor is about the same as the supercharged 4.6 DOHC cobra motor that I pictured. Impressive to see it in the bay of that Celica, which I assume is similar in size if not smaller than the mk2. I know basically any engine can be put in any engine bay with enough encouragement. The pictures of his cross member are impressive, however quite low to the ground. It makes the amount of custom I had to go through look like nothing.

It looks tighter than it really is. I put the exhaust manifolds on after installing it w/o having to lift it off its mounts. Thanks! It is a 1997 Cobra 4.6 DOHC which was not s/c'd. They only supercharged DOHC's in '03 and '04 for Cobra Mustang and now again for the Shelby GT500 IIRC.

Right. Close in size. The s/c'd version must be taller from what I have seen plus they relocate the alternator to the side that makes other fit issues. I never considered the s/c version as it was not in my budget.

The cross member was made low to help protect the oil pan. I've lowered my Celica 2" which makes the oil pan vulnerable to a fatal hit. I still have 4 1/2" clear to the oil pan and 5" to the cross member. I can also pull the pan w/o pulling the engine (in case I need to).

Every swap has its challenges. My hat is off to you for getting it done with the 5 spd conversion (I followed your build thread :thumbsup: ). Some of the V8 conversions just kill the driveability and fun of the car unless all you want to do is win burn out contests.......your's keeps the Supra well balanced and I bet a blast to drive.

[Jkm3141]

Wow, that is impressive. Idk if you saw the part of how i had to put the exhaust manifolds on. It was a pain, Chassis mount bolted to engine mount, and put the manifold on and drop the engine down. It worked but was tight.

Is the cobra motor front sump or rear sump? It looks like a good setup you have there if you can pull the pan without the engine, not that you would need to often. I don't quite have the fabrication skills to make a crossmember. I am just starting learning how to weld so I can make my exhaust, which is also why I haven't driven my swap much at all yet. From what I have it is a blast. nothing but wheel spin in 1st from about 1800RPM on if I am on it hard. I do need new tires badly though.

The 5spd conversion really made the swap just that much harder, I will say. However its totally worth it. I couldn't imagine doing that kind of swap and having it automatic unless you particularly want that setup (see junkies Automatic build). It also adds to the rarity factor, which is a huge plus for me. I love having an Mk2 because there are less than 5 in Rochester, none who are on CS.com or really build it at all, which makes it cooler for me to have one that is at least having an engine buildup if not a clean body.

What would you say the measurement between the strut tower and the top/side of the head is? I would put it at about 2 to 3 inche on the 1UZ if my memory serves me right.

Yes. Sim problem on RA65 Celica. I have a friend on lextreme.com doing 1UZFE in the little brother to your car.

Rear sump. Steering drag link would go right thru it if I didn't convert to front steer rack and pinion.

Almost the same. I just measured left side at 2 3/4" to nearest point toward back corner on tower. It's 3" near the front edge. Motor is centered in engine bay so, same clearances for right side.

Yea, Phil bradshaw the guy I got my transmission adaption stuff from and the wiring from is doing a swap into an 84 or 85 Celica Coupe. He lives over in New Zealand so its RHD and a tad bit different but would be even more a blast than the mk2 as its lighter weight.

I saw on your site the pictures of the front steer rack and pinon. Do you have any more details or pictures of this? I am just interested in how you did that, not so much because I need it. i have seen a few other people doing major modifications to the steering and am always curious to see others. I was tempted to try something like that to make the angle on the steering column better to clear the manifold, but worked out the manifold differently.

Hmm. Do you have a measurement of the the width of the long block? I believe the 1UZ is 700MM plus or minus 5MM, which is roughly 27.5 Inches. I'm just curious.

I just love exotic swaps. Thats part of the fun on lextreme.com, seeing all the people who throw that v8 into crazy cars. My favorite has to be the mk1 MR2 that guy did with a complete custom rear frame and suspension setup.

It's meant to be an overview of the project. I know some of the Aussie's and Kiwi's about. My Celica was in Autospeed before this transplant. There are many details that are not published on my project for now.
