This thread makes me happy on the inside. GJ!

I'm just wondering if you had a 2j motor why did you decide to keep the 1j head, why not just put the whole 2j in there. You prob said it somewhere and sorry if you did, I want to do a 2j swap on my s14 so I just want a opinion before I start buying everything. OH and beautiful swap and car I am very jealous.

He already had head work and cams on the 1j.

Ding ding!
Exactly xD

Really the cams made the difference. The HKS cams for these engines are stupid expensive. Also, I do go to school away from where the car is located, hence why I've been working on this non stop. I would have love to have a complete 2JZ, but this route allowed me the quickest, cheapest way to have my car up and running.

Thanks for the compliments everyone. More progress today I hope!

Jesus you do real work.

Successfully fired the engine tonight. I'll update later with a video of the initial start.

By competitive are you talking FD? cause i do events monthly.. this is my track car and is very purpose built. I'm running MDU events and will probley hit as many pro am/xdc events i can this year.

and i have very little understeer, if anything my car has oversteer, like i said no plowing and im only running a 215/45/17 in the front of my car

Stand corrected on the torque, checked my own sheet, my bad.

and as for the the motor mounts, I guess i should have said engine instead of motor. Mounts that bolt to the block, not crossmember.

what did you do for your exhaust? im assuming custom work but how much clearance do you have and where does it run to

aled

Update for everyone.
Engine starts, runs, and idles great.

I've been running through the car fixing leaks, however. The heater hose pipe leaked, but is fixed. Next, apparently the oil drain gasket on the turbo broke, and leaked oil all over the manifold. I am going to re-make the -10 drain line with new gaskets and AN fittings.

Only concern remaining is confirmed seal of the headgasket.

Now, when we first started the engine, there was considerable white smoke exiting from the exhaust.
- Ran the car for about 10 minutes achieving about 140 degrees, slightly milky oil cap.
- Drained the oil with surprisingly almost no water/coolant in the oil.
- Fresh oil, started again, ran for 15 minutes achieving nearly 170 degrees.

Once the oil leaks are 100% fixed, I'll have a much more accurate confirmation of a proper headgasket seal.

I will be back in town in about a week to work on the car again.

Just a short video of the exhaust to show the usual white smoke from improper headgasket seal has cleared up.

Prove It

good deal. i was going to say you should have copper coated your Head gasket.

looks good man. you've just made me want to go 1.5 with my JZ.

sick, dude. What spring rates are you running??

what did you do for the oil galley on the head [by cyll 6?]

tuktuk23

effin dope!

I was wondering the same thing also, so good to know.

Is the 1j exh mani able to fit the 2j head?

And how did your old motor detonate?

Was it bad gas, over boost, or what?

Btw, you're gonna love that 2j bottom end.
The extra .5L is noticeable down low and out of boost.
It also helps to build boost quicker.

And IMO, get a retune.

aled

HEY
Thank you.
Only do so if you blow your 1JZ up...
Powered by Max Coils 10/8.
This is the GTE engine.
As I understood, oil modifications were required for the GE bottom end.
No, the exhaust manifold won't fit. Had that been the case, I would have just thrown the 2J in there and rebuilt the 1J on the side.

Old Motor detonated with bad gas X__X

collegekid

How much did you end up spending? You can pm me if you dont wanna tell the whole world. i've been researching this and several other options and i got it down to 1jz vs ka-t. good job on your build, read your entire other thread too, shit looks amazing

IBoughtAS13

Oil modifications are not need for the 1.5JZ. I have all three, a 1JZ, 1.5JZ and a 2JZ. The feed hole is on an incline.

How do I know, I did a huge write up on SupraMania.com in the 1JZ section. "JZ Swap Guide For Dummies". Name is IBoughtASupra on there where I sell catch cans as well

aled

A fair amount for such power levels.
As far as the JZ vs. KA-T, cost discrepancies will be significant.
Build what best suits your budget and ability to maintain the engine.
Great!
I've been through that thread a few times. I'll be sure to contact you if I have any further questions regarding this headgasket sealing issue.

driftwhat

Wow nice work man, keep it up.

Just a small update.
The 1.5J is now running beautifully. Even drove it up the street today.

Anyways, the previous -10 oil drain I used on the 1J was too long. Oil was backing up and blowing out the gasket and through the seals in the turbo. I drastically shortened the oil drain which quickly alleviated that issue.

I then ran the car for a solid 45 minutes, bled the cooling system. The next day, I compression tested the engine.

Bam. Perfect compression across the board. What a huge sigh of relief. Drove the car around, idled at 13.5:1 A/F Ratio. Over spring break in a few weeks, I'll get the engine re-tuned for the extra displacement of the 2J bottom end.


Turbo off to change the drain line. Probably the 5th or 6th time I've had it off in the past two days...

About to compression test the engine. Hanging out with the 86 190E 2.3 16V.

Oh yeah, then I sold all my drift spares and got all matching wheels !

Put in my matching Recaro too!

So long for now.
Trying to track down a HKS DLI. I'll wire that up, take it to get dyno tuned. With the HKS DLI, 2J Bottom End, and the same boost level as the 1J (18.5 PSI) I expect about 550 wheel, and about 470 torque...

I'll be sure to actually take a video of the dyno this time xD

robots

What turbo do you use ? What turbine AR ? When is full boost ? On 1jz compared to 2j ? How is response ?

aled

60-1, .70 A/R
I was about full boost on the 1J just under 3,800 RPM.
I don't know on the 2J yet. I need a re-tune before I can even think about boost. I'd imagine with the extra displacement the spool time will only get quicker.

IBoughtAS13

It will be much fatter under the curve. You will hit that boost even about 800-1000 RPM sooner. That 60-1 will spool utterly quick, a 6262 will be in your future. It avoids the lag of a 67 and is super responsive for your power level.
