Builds 80 series where to start! Again.... (16 Viewers)

[OFR04D]

Are you going to mod the axles for castor, scrub radius, Ackerman, etc and poss slight bend for camber? Custom radius arms to match the drop?

Very nice, 850 hp from 1FZ+turbo is not difficult

the 1FZ has great potential, I just built a 2005 1FZ-fe engine and swapped it in my 80 instead of
the old carburated one it has:
* 102.5 mm cp pistons.
* Crower cam (forgot the numbers)
* +1.5 mm Manly valves
* the head is 1mm milled and ported
* 90mm throttle
* Exedy clutch + Fidanza fly wheel
* Haltech.

it has about 280 rwhp and I it's my DD. I am waiting for your project results, so I can start mine

That would be quite a trick bending the axle to get caster and still being able to get the axle shafts to line up in the 3rd

But what you could do and I have thought about it is use Slee's offset camber bearings but instead of using them for caster mount them 90 degrees and get a degree of camber. Only works in the front but might try it.

Ackerman angle should be fine as long as I can get the front axle rolled forward to a more stock location which will probably mean custom radius arms. I would like to do them out of aluminum.

Thanks, it sounds like you have a nice setup.

Weren't you concerned going 2.5mm over stock? That seems like a lot of material to remove. Did you have a custom headgasket made? All of the ones I have seen are 101.5mm bore.

You are also lucky to get the manual transmission, that's not something we ever had in the US so I will be making due with an automatic.

My current turbo 80 makes 350awhp through the auto and fulltime 4 wheel drive. I have a build thread in my signature if you want to check it out. I have a feeling this one is going to take a while...

Truck won't get a cage, but will get harness bars.

You might want to read up on using racing harnesses without a roll cage. Could be a death trap in a rollover.

I saw guys boring their cylinders to 103mm, it removes a lot of material but there is no concerns. The gasket is stock.

I've already read your build thread it is so interesting, I was convinced with the turbo . Swapping the engine is my first step, may be after a couple of years I intend to add the turbo and make the necessary changes. I want 450rwhp

Well it is happening. The idea of building a muscle truck just won't stop. So I am doing it.

Goals for this project are <4500lbs, more than 850hp, retain all wheel drive, seat 4 in 4 buckets with harnesses. (these just coincidentally happen to be slightly better than the Hellcat numbers. lol) Can this be done? Who knows but I think so.

I am still looking for the right candidate for the body, but I have started buying parts. I know this flies absolutely in the face of all that is right in the Ih8mud world but just think of it as Supra's big brother.

I only read the first few posts.

So you are going to try for 850hp out of the stock motor?

I think getting to 4500lbs will be hard unless you remove most all the body and cut up what is left. If you do that I see no major dramas in getting the weight down. If you leave it full bodied truck I just don't see that happening. My 80 was 5300 bare bones stock.

Can it be done? Of course! 850hp out of the inline-6 though sounds expensive. And can it take it!?

Cheers

I am pretty confident I will meet my goals so I guess we will see

No those are guys that are mounting their harnesses to the floor and not to a harness bar. The harness when mounted to the floor basically acts as a spine compressor in some types of collisions. The rule is between 45 degrees and 90 degrees from the driver's body. The other concern is people that run an anti-submarine strap but no cage, this doesn't give them a way to move if they cave the roof in. I am comfortable with my decision.

Transmission in-route from Gagel's Auto Parts to ATF Speed. They are going to try their best they said but no guarantees. Fingers crossed that A343F shares most if not all interior parts with the A340/A341.

Head parts should ship in 2-3 weeks.

Confirmed the new TE37 Ultra wheels on Ray's Japan website will be coming to the US around the end of June/July.

It is all coming together even if it is still mostly in my head. ha.

This is bad ass! I grew up around mean turbo cruisers in Dubai! Can't wait to see one terrorize the streets!

Ill be following this. I like the power and tranny mods. I'll be watching to see what performance upgrades cross over from the 340 series. I wonder if one of their valve bodies could be used with PWM rail
pressure control.

Not sure on the lowering a solid axle vehicle. I would guess the 100 series independent would be a better fit and handling. In never looked close to see if it's all Ina. Crossmember or what kind of steering box/rack utilized.

Some short throw 2.5 body shock should keep it stable and you can tune them as you go.

Thanks for sharing look forward to more

 

[scottryana]

Thanks, and yes the ifs 100 series front end would probably be more ideal, but they don't have a 1FZ engine. Having already had a boosted 2UZ, I can't very well do that again. SO short of a 1FZ in a 100 series or swapping a 100 series IFS onto an 80, it will just be a solid axle with slight camber and hopefully corrected arm geometry.

Funny I used the LS swaps and Diesel swaps as a way to sell ATF Speed on working on the A343F. At first they didn't really want to have much to do with it. I told them that there are quite a few people who love Land Cruisers and are doing re-powers and could definitely benefit from having a proven stock auto transmission. If this turns out great I could see it being a benefit to people doing swaps as you would only need the engine and adapter.

I think I mentioned earlier I was looking at doing 2.5" air shocks with reservoirs but their capacity is just not there yet. But yes at sometime in the future. Cutting off the spring and shock mounts and doing a 2.5' short body coilover could be just the ticket. But initially it will be cut coils.... :-(

Was a little worried about trying to find someone semi local to do a real quality turbo manifold for me. But my good friend Marc is going to take a break from making Viper twin turbo manifolds and take a stab at this old crazy truck idea!! Very pumped to have what I think is one of the best fabricators I have ever seen on-board!

 

[gahi]

Whoa! Sounds awesome! Are you building this locally?

I'm only curious about the cost.

Between here and Denver. I will be using an engine builder that Slee recommended over in Denver. The transmission builder is in FL. The turbo manifold fabricator is in Dallas. So I guess it is kind of being built all over and bolted together locally. lol.

Well tires are ordered. Had to tell a slight fib to Tirerack as they wouldn't sell me the tires I wanted.

The stock LX450 tires are rated at 2355lbs carry capacity each.

The tires I wanted would only carry 2337lbs each.....

18lbs each per tire but the total capacity for 4 tires was still over 9,000lbs and he was giving me grief about using them.

So this now just became a tube chassis race car if Tirerack asks. lol.

 

[scottryana]

Their fully rebuilt/built A340/341 transmission is $2700.

Hell, a Wholesale Automatic's valve body alone is $1300 so $2700 to have a fully rebuilt, bad ass'd trans is
