My buddy CJ has had many rape machines in the past collecting parts through out all of them, 78' 280z turbo, 96' Eclipse turbo, 70' 240z, & now an 85' RX7. He wanted to do something different so A mixed breed baby of a car was born through lot's of money, well over a 1,000 hours of fabbing, fitting, rebuilding, tuning & bitching lol. This is an 85' RX7 with a 70' 240z dash & console swap, First ever RWD 420a mated to an R154 trans. We've both had our hopes & expectations but some doubt's at the same time. And we were both very impressed at this past drift event Drift Valley III ( Facebook it ), The car ran flawlessly making awesome power as you will see in the video this is driveway tuning at it's best.[video]http://s1148.photobucket.com/albums/o578/nzty420a/?action=view&current=VID_20120926_181705.mp4[/video]

This was defiantly A though at one point & time But he figured it was a little over kill lol

Any questions please feel free, Any criticism go F yourself lol

My buddy had a 420a eclipse with cams, int and exhaust. Kept up with my 94 Eldorado northstar, he was also NA. They are under estimated engines

 

[SidewayzMKII]

They are, And including that you can go full forged internals for about 1,000 & make well over 500hp is pretty impressive as well. Right now were just milking it waiting for something to happen, Cause as soon as this motor goes he's replacing it with a 2.4 bottom end. But the way it's running it doesn't look like it's going any where soon :thumbsup:

 

[suprasouth]

Darn cool man. Why 420a not 4g63, maybe had a built 420a from previous eclipse? I'm
digging the dash swap, and the nerve to do this project. Good job and thanks for doing something
different, seriously. Any plans to mash out the details, for look and i.c.e.?

 

[SidewayzMKII]

Thanks dude, & yeah this engine came out of his previous car. And a body kit, wheels, & some black interior from a soon to be bought parts car all coming. I will update this post regularly

 

[mk2 supra]

Are you sure its the first??

nice build though

to be honest, if people with the 2nd gen eclipses did their homework they would realise that the 420a is a far better engine than the 4g63, ive had eclipses in my day. if people spent just as much money on a 420a as they did the 4g, they would come to realize what i mean. and when i talk about the 4g i mean the 6bolt, not the horrible 7bolt.

In the same way its sometimes smarter to Turbo a 2jzge than a Te yes, only because of a lower price due to less demand. Is there any reasons in the engine itself? Cause i daily drive a 12 sec 1g dsm and know for a fact the 4g63 is an AMAZING engine. I have 207k on the clock, I've put 40k hard miles on it. Not a single major failure. 22 psi, 8000 rpm, whatevs. Idk if it was rebuilt before me but im leaning towards no, seeing how the stock longblock record of 10.35 and 550 whp is with the same mileage.
But i do strongly disagree about the 7 bolt comment, steer clear of a 96-97 without a rebuild and youre fine. Think of it like a 7m without the head torqued.

 

[SidewayzMKII]

Yeah dude 100% it's the first true 420a RWD ( there's a RWD drag car with a 420a in it but it's no where near an actual 420 it's custom block the whole nine yards this is a real one from an econo shit box everyday eclipse lol not custom everything made to similar spec ), 4G63 is completely different. There's plenty of those now they even have there own site dedicated to the swap ( that zero G site ). There's been a few try it in the past on 2GNT but have failed, And these new pics will clearly show that not only does it run & do massive burnouts but it is a fully functioning drift car with a very successful first event. I also added some more pics to the original post enjoy this was history in the making.

By the way that BMW in the top left corner had a 1J swap it's to bad I didn't get any pics of that

Not bad for the first track day & Him having less than a few hours of drifting experience, I see lots of good slides in the near future. Next month is a practice day at summit point, Today we made camber plates that turned out awesome we both cannot wait to see how much of a difference it made.

yes and no, its way different. the 2nd gen eclipse came with two engines, the 420a and the 4g63, just like the 1st gen came with three engines. you compared the 420a/4g63t combo to a 2jzge/2jzgte. the only reason why the 2jzge is easier and cheaper is because its not setup for the turbo and it has no turbo. you will spend the same amount buying the aftermarket parts if its turbo or not, and will come out to almost the same amount of hp depending on the person. now as for the 420a and 4g63t, it was easier for dsm to make the 4g since they had all the parts in their hands from the previous years. why would dsm spend money making a stock turbo kit for the 420a. the reason why the 7bolt is worst than the 6bolt is because 1) crank walk if engine isnt rebuilt, and 2) the ports in the head dont open up like the ports in a 6 bolt). alot more people do a 6bolt swap or they go 4g64. ive owned both a 1st gen plymouth laser and a 2nd gen eclipse with the 6bolt swap. i did my homework before getting the eclipse. wish i would have gone 420a.

Hey this is my car and thanks justin for making this build thread . now look this is not a thread that needs to be jacked so please argue elsewhere . Any questions about the car feel free to ask thanks .

Now look this is not a thread that needs to be jacked so please argue elsewhere . Any questions about the car feel free to ask thanks .

LMAO, the apparent king has spoken people, move on people this is HIS thread. PUBLIC forums are places for the PUBLIC to connect with others in a PUBLIC way. The way I see it, you didn't even start this thread, so bitching about people arguing in it is kind of pointless.

420a is a throw away engine, dime a dozen, blow it up today, pull one from a number of different cars in the junk yard tomorrow and be driving again in a few hours. A good friend of mine had a custom made turbo Avenger 10 years ago, he ran through 3 blocks in a short period of time and sold the car in favor of a Stealth RT/TT.

My view is, you found a sub-par engine to put into a car/setup it never came in. Yes you are the first, and its cool that you have the skills and knowledge to preform the swap, but I don't understand the point besides being able to say you are the first one to do it.

Props on the swap, it looks like it preforms as intended, I just do not get it is all.

 

[SidewayzMKII]

No need to be a smart ass he spoke the truth plain & simple, And people should have enough respect to post decently. We both don't want a bitching match to break out about how good a 4G is. We both know there amazing engines for there size. And the reason this was done was for way more than saying he's the first to do so that's just a great bonus. 1: The engine was already boosted running smooth why shit can it? 2: Like you said yourself there a dime a dozen if you blow it up so what we'll go tomorrow & pull another. 3: If you do research on this motor you'll know that the head is one very tough & two that the head is completely interchangeable with the 2.4 which I can find multiple cars pushing 400+ HP with just fuel & boost turned up on a 2.4. 4: A 2.4 can be had for dirt cheap as well & SRT-4 internals are compatible there's people making over 500 hp. The original game plan was to just do this set-up & swap in a 2.4 when it blows, but the more research we did shows that the 420a is a more than capable engine. A 420a is stud girdled from the factory & people are making 400+hp with forged internals with a stock crank & stock head. You can get forged rods & pistons for under $900 that's cheap, but before you go forged you can simply get a 2.4 block & swap in SRT-4 internals & make 500hp for cheaper to equal prices. Either way you look at it that's impressive & that kind of power in a barely over 2,000LBS chassis is insane.

 

[mk2 supra]

Yes that is very impressive. I totally get the swap and why it was done, this year rx-7 is real light and with a straight axle would be nice and strong for drifting. So I actually asked this on my mobile but it didnt send, has this car been on a scale yet? Id love to know what it weighs in at.
btw love the build and great update on the first post

 

[SidewayzMKII]

No scale yet but it will happen soon, the car in the pics is actually mine now. The original owner just picked up a great condition 83' RX7 for real cheap, with damn near perfect interior. Now the swap begins again, I'm gonna take pics & post through the whole swap. And I'll get mine in here as we decide what motor to put in & go through the process.:thumbsup:

 

[cj011]

so the R154 bolts up to the 420a or 2.4 SRT engines?

 

[SidewayzMKII]

yes using a shortened jeep 2.5L 4 banger bell housing. But it won't bolt to the SRT block, It will bolt to the cloud car 2.4 engine block which is diff. from the SRT block. But SRT internals can be swapped into the cloud car block.

 

[cj011]

when you say cloud block, do you mean the 2.4 n/a?

Don't quote me on this, but I think the bellhousing pattern for the SRT block is only one bolt hole off from the "cloud" block. When the 8 valve 80's turbo dodge guys drop in the srt-4 blocks, I'm pretty sure they have three holes that line up and don't even bother with the 4th.

 

[SidewayzMKII]

yes i mean na and if that can be verified that would be awesome since there's only three bolt in his bell housing to block anyways lol
