Please dont move this thread to 1jz/2jz... everyone thinks that 1jz swaps are very costly... its not really. i want more people to get into this swap, so we can all learn more about this engine. then we can hav more manufacturers making parts for us.

1jz swaps are easy to swap and pretty cheap compared to other honda engines. 1jz arent as costly as everyone thinks. Just time consuming. heres how i got there.

1jz front clip. $2,000
selling my 7m parts:
rebuilt 7m engine and tranny - $1,000
wire harness - $200
91' ecu - $90
91' intercooler - $150 <----- ebays a great place to sell this
HKS Fcon - $250
HKS EVC - $200
AFM - $50
and a set of rims $300
already thats more than $2000, plus i sold a whole lot of other misc 7m stuff... i basically sold my 7m setup and got money for 1jz. Shipping on the other hand was another $1,000, but 1,000 for a newer tranny and nice smooth engine is totally worth it to me.... what is a $1,000? just an exhaust and a new boost controller is $1,000 already. i think its totally worth it. So far i spent $1,000 on shipping and a lot of time wrenching w/ my cousin, which was priceless~! (with his whining and yelling)

How much money did you guys spend on your swap? so everyone knows..... I know lenny made alot of money selling his 7m stuff.

On the pure swap parts alone I've spent ~3600 and I recouped about $2400 off my bone stock 7M-GTE parts and leftover clip parts.

As said though what nails you is shipping sometimes... and me being in Canada... it wasn't pretty. Bring it home yourself if you can.

HKSSUpra, where are you located in NY? I think I have seen your car on the road. I am in Flushing, you look like you are nearby. PM me, maybe we can meet up. I got the Supra in my garage right now, finishing the rebuild.

umm dont know if youve accounted for this but you also need to get the harness changed to lhd and if you dont do it yourself thats about 400 bucks...

an there are a lot more things then just the clip most of the time...it really depends on what clip you luck out with .....

i feel sorry for those people who dont do the harness themselves and spend a rediculous amount of money to get someone else to do it. wasnt it like 700-900 bucks for a Mike Urbano harness? and it took some 9 months to get? heh, fuck that.

yeah, some people luck out with some really cool shit on their 1j clip...some get shafted.

does anyone have any success or horror stories about their clips?

89 Supra spent 3500 for a complete clip and 700 for the harness installed.

Again you are looking at some serious loot and time to put in-if you have a 86-88 car plan on spending some time positioning the motor if you don't have the newer crossmember.

So you are saying that the 89+ crossmember isn't required... its just makes the swap easier?

Not to hyjack, but to counter, I'm looking at spending 2300.00 for a stroker kit for my 7M.
I suppose the 1JZ will out rev the 7M, and especially the stroker, but I'll have much more around town tourqe, and that is where I drive my Supra. (Besides, on the highway, I can already do 163mph, so who needs to go faster?)
I like the 1JZ, but for what you get, your still going to need to spend mega bucks to go single, and add more fuel. (Just like a 7M, only that motor is "free")
Keep up the good work 1JZ guys, you keep me thinking about changing everytime I see a high HP 1JZ.

No, it wasn't . It was a little more than the price of a brand new 7m harness which is what we started out with since my stock harness was pretty fried. It took less than two weeks to receive mine from Mike

It's required. I tried to mount it up without it... trust me... it's required :) (if you actually want to know your engine isn't going to torque out of it's mounts)

With that I bid you all adieu for the night.... my 1348'th post will happen next year :)

Happy New Year to all...

What's so different about the new crossmember? I've never actually seen any pics of the 2 of them to compare.

Oh ok... make me do 1348 tonight ;)

It's even hard to see in pics... On the newer crossmember the slots that the rubber mounts sit into are lower by about an inch. Also the new "round" rubber mounts are about an inch longer than the old square ones to compensate. Toyota did this I think to reduce engine vibration.

There is also a slight angle difference. That makes using the square mounts a problem. If you use the round mounts (an inch longer) on the old slots (an inch taller) the net result is that the engine sits too high. Also... due to the fact that the mounts form a triangle... with some nifty geometry (I mean to diagram up somtime) you can also see that the mounts will now be a little too far apart to seat into the bottom of the old style slots. The result is: The engine WILL sit in the car but it's too high, and it's sitting at the top of each slot. If you force it to the bottom of the slot on one side it's very close to popping out of the other slot. Bolting it in like that would be very insecure.

There are a lot of possible solutions... custom mounts... slot modifications... yadda yadda yadda... I have heard them all discussed. But it's far easier to just put in a subframe that fits how the 1J was intended to mount. :)

NOW I'm off to enjoy New Year's.... have a good (and safe) one everyone!

WOW, i'm not sure what i'm up to as yet.
Let's see...
1400 for engine
300 for JUN Flywheel
600 for Blitz Access Rom mapped for 550cc's
250 for MKIV injectors
365 for F-Con and engine wiring harness
150 for HKS GCC
600 for Trust 1JZ FMIC
215 for HKS BOV
70 for Timing Belt
300 for 1JZ bell housing

That comes to let's call it $4300 and i still don't have a crossmember, clutch, powersteering hose, motor mounts or throttle cable. Hmmm... Did i do something wrong. Oh wait! no i didn't, b/c even with the stock CT12a's i should be pushing 325RWHP :)

I'm glad that i have money to spend something on. I am by no means wealthy. If i was i would own an MKIV. But since i just happen to come upon parts and upgrades for a great price, i can't pass them up. So my engine is STILL siting in my garage. DAMN IT!!!! Still waiting for everything and time to finish the project.

I am soooo looking foward to my 1JZ.

Ok, 4300 for a 325rwhp motor that loves to rev, and admitingly has some potential for more. (With another 5k spent for custom single/manifold etc.)
Or, for 4300 you can build up a very nice, CT based 7MGTE that will give you over 400rwhp and have spare change for other mods. (Or you can spend it all on the motor/turbo/AFC, and have 500+rwhp.)
The way I see it, you can be unique, or fast. I pick fast. :)
On the flip side, give it another 5 years, and the 2JZGTE motors will start going down in value to a more reasonable price. The 350z/G35, WRX/STI and EVO are all becoming the "Popular" upgrade cars. The F&F movie hype is starting to finally wear thin, and the price of MK4's is going down where it belongs. As this happens, the cost of a upgrade that is worth the money, 2JZGTE with a single and a 6 speed, will become a reality for more MK3 owners. (Or we will just buy the MK4's at prices that reflect what they are, 10+ year old cars.)
One more thing to consider. I was talking to a shop that does stroker kits for the 7M. They built up the R&D motor, figured out all the specs, and then started to market the kit. He says response to the kit caught them unprepared big time. The waiting list is 8 to 10 weeks out, and he just ordered rods for another 28 kits. (That is a lot of rods.) Tourqe has always been the nice part of driving a MK3. (Or any Supra for that matter.) I6's have a very nice tourqe curve, and the longer the stroke, the better the curve. Tourqe is what makes your car fun to drive around town, and on the highway. You don't have to shift as much, you get better fuel economy and clearly the 7MGTE and 2JZGTE will make tons of HP on top, and the tourqe down low. (Not something a 2.5L will do easy.)
Finally, with better valve kits coming along for the 7M, larger stainless valves, new springs etc, and port work, this motor has been proven to flow as much as the newer designs. The power is there, we just have to find the tricks to unlock it.
Happy New Year!! :)
