I think you should just go ahead and make a stack coming out with a clapper. Builds looking good btw.

Got a little work done today so far. Got the cage is mocked up just need to drill some holes, walbro 255 installed, found a giant mouse nest on top of the fuel tank and fuel pump so I have to fix some wires but it looks like it is contained to just the area under the fuel pump cover but I am going to keep an eye out for more chewed wires. Here is the pics of the cage and rats nest and the fuel pump installed in the modified sender.

Friggin mice. I just pulled the motor from my wife's Sebring and there' was a nest both under the air filter and intake manifold. And the car was driven regularly.

We'll have to check each others cars out this spring/summer sometime. I'm 90% done with an LS6 swap. In Anne Arundel County just south of Baltimore of I-97.

Not really a big deal.. in the IS community they just use a larger head gasket and still rock 350+ rwhp on the stock motor.

If you read the thread you would see that he has already addressed this, hes not trying to make a million hp

The engine that is in my car is a 2JZGE not a 2JZGTE the GTE is the turbo motor but I have put a GTE head gasket and plugs in my car so I can still run upwards of 18psi of boost and be fine and the GE motor will make 500 HP with the stock internals it has. If you take into consideration that a GTE motor is $3000-$4000 and a GE motor is $1200 than the $800 to put pistons in and do some machine work to have the same thing as a GTE is no big deal. If my car ever makes it to 500hp and I decide that is not enough I will just get a GTE bottom end and throw more boost at it, but for now it will be fine.

you really have no clue how fast your car is going to be if you can get traction huh? I HIGHLY doubt you will want to cross the 500whp mark with this car lol. Good build btw.

I really don't want to cross to far over the 400hp range I have ridden in a legitimate 300hp miata and that was a handful so I don't want to get crazy unusably amounts of hp in a little car. I will shoot for 400 and if I accomplish that I will move up slowly until I think it has more than enough for the car then come down a lil. I also have nothing to judge this car against on how fast it will go there is really no good comparison to say it might do this or it might not do that. It will be a learning curve to say the least.

Got a little work done today its snowing pretty bad outside so I can't go to the store and get parts so I have to do what I got. I did get some progress though. I installed the roll bar most of the way need to tighten the bolts for the down bars. I picked up a set of sports brakes complete (used) they came with everything calipers,brackets,two sets of rotors, and pads for $150. I got my alternator and water pump pulley installed and they look great. I also remembered to pick up some nice hardware for my rollbar from work. Nice stainless cap head bolts. I will post some pics tomorrow of the calipers and rotors installed, and anything else I get done.

Here is a couple pics of the snow in Mt. Airy MD right now. This is out of control. The one picture is of my dogs out of the snow for comparison. The brown one is 65 lbs. and lanky and the yellow lab is 80 lbs. so you know they are not small dogs. I don't think I'm gonna be leaving the house any time soon.

The housing is out getting an elbow welded on and I was mocking up the oil return and the guys at the shop know someone would die if they broke my turbo.

i dont think he intended for it to be pretty. nor do i think he wants to spend the time to make it the prettiest thing youve ever seen. who really cares about looks anyways? **** it. id much rather have a faster car that performs better than a production car worth 30 grand or more. and it really doesnt matter wether or not they think that it was made better then their corvette or not. chances are they dont know any of this; less weight, less cylinders, smaller wheelbase, smaller tires, better suspension, older platform, weaker transmission than the corvettes (w58,) smaller rear differential. the list goes on.


take ur prettied up f20c swap and go to a car show jk

That being said, I respect that it is you ride; whatever makes you happy is cool. It's just not the way I would go about it.

Good luck with the rest of your build I will still be checking it out, and enjoying your progress. Cause weather I agree with your approach or not, I am a gearhead and I like performance, you are a gearhead and like performance so I respect what you do!

You left out an important part of my post when you quoted me. What the OP is doing is cool. Just not my cup of tea. IMO a conversion needs to be under the hood, not sticking out like a sore thumb (again this is my preference). I don't care for super shorty exhaust/dump tubes either. I highly doubt there is a cop in the world that would not pull this car over for loud exhaust. No muffler no cat...no thanks. Ear plugs will be a must while driving this car (if you value your hearing).

My idea of a successful conversion is one that will still allow me to use the car as a daily driver if I want to. One that I can leave outside in a rain or snow storm without having to worry about filling the engine full of water, or worse yet, sand, grit, or grime.

When complete this car may be a hell of a track bitch, but it will fall far short of what I would consider a quality conversion. (My opinion, I am allowed this)

I stress this again. It is Sean's build not mine, the only guy he has to please is himself. I am intrigued by his build though not interested in having one like this personally.

Keep up the good work Sean, your solutions to problems with the build are what keep me coming back.

By the way Banks, it is common practice and grammatically correct to capitalize the first word of a sentence in the English language

I am not trolling for a fight, so lets just agree to disagree!

I have to say that with more time and money I could have gone about the swap a little different. I would have loved to buy a tubular crossmember and used a GTE and some other quality parts for some of the stuff like the turbo. I have to say I love the critics because the more people that make comments good or bad help my project and will help the next person to do it. I have hopes that if enough people do it than one day there will be a semi kit like the guys with the LS1 kits. I wish I could have made all of the motor under the hood but I dont have the fabrication ability to do so I wish I did. I am hopeful that I can used a cowl hood for like an old muscle car and adapt it nicely to my hood. I mad up some cardboard templates the other day and it looks like I can use a 4 inch cowl and it will fit under the hood. As for the exhaust I like the hood dump but at some point I am going to try very hard to at least get it under the car. As for the police I will do my best to avoid them and I only have to make it 2 years before it is historic but we will see how that goes. I will keep everyone updated and I really hope to see more of these conversions so one day I can buy a 97 and up and put a 2JZ in it with a lot less problems. Please keep the comments coming good or bad.

sean, you should definitely make some extra mounts and sell them!!! it would definitely make more people wanna drop jz series motors into their cars, many people dont like the fact of fabbing **** up simply because they dont have the skills or place to do it.

anyways, ever think about a 1jz swap? it would be a great alternative to a 2jzgte or building up your own na-t. about the same amount of money. the blocks are similar.

i think i would go this route if i were to do a jz swap. or if money were a real concern, n/a 2jz for now.

The next time I do this or most likely in this car when I change the motor I am going to build a 1.5 JZ. The 2JZ GTE bottom end with the 1JZ GTE head. The 1j head flows better and the 2j block makes more power. The best of both worlds and this set up is about 1 inch shorter in the head and the intake manifold dose not come back over the engine so that would be even more room.
