I'm in the middle of swapping out 1JZ's in my JZA70. My replacement engine did not come with a wiring harness (engine only) so I will be utilizing my existing one. Just wondering if there are any guide's out there for doing this? Is it worthwhile/necesarry to remove the intake manifold? Any...

Quick question: does anyone know if the US and JDM use the same condenser? I have a 1990 JZA70 and looking for parts. Thanks!

So, just got my car out of storage yesterday and took for a first drive. After an hour or so of easy driving I opened it up on the highway and right as I hit full boost (~18psi) it was like I hit fuel cut and lost power (have HKS FCD so I know that's not actually what it was just same feeling)...

I just finished installing my new 264 cams and when I went to start it it ran very rich and sputtered badly. I took it for a short spin around the block and lots of hesitation, sputtering etc. I was careful to follow the installation procedure very closely but it seems that somehow the timing...

So I am in the process of installing my BC 264s and when I go to take them out of the box and put them in for the first time I noticed the one tab is broke off on the intake cam. After searching in the box I found the broke off piece. I'm guessing this must have happened during shipping but...

Can someone tell me if I need to drain all the fluid out of the hydrofan if I need to remove my radiator? If so where's the best place to drain from? Thanks,

For some reason JZA70's don't have dash dimmer switches but I am wiring in an EBC and would like to at least be able to dim this since I plan on mounting it on top of the steering column. Is there something I can pick up at an auto electric type store (rheostat/potentiometer) that would work...

These are both around the $300 price point give or take. Anyone have any opinions or experience with either?

I know there are a number of threads similar, but can't find exactly what i'm looking for: I wired in a GM 3bar MAP into my Apexi Neo and into stock ECU, hoping to be able to raise the boost over stock fuel cut. Now it runs like crap, backfires, stalls out, etc. I tried playing around with...

The other day my speedo started really jumping around, became very loud, and finally quit working all together. I detached the cable from the tranny and the cable was all twisted and frayed. My question is, does anyone know if this cable is the same as the cable for the north american R154...

Looking to replace the fluid in my stock JZA70 differential with around ~150000kms on it. This is the 4.10 diff. Not sure if I should go with the 75W90 with or without the friction modifiers? thanks,

I want to extend my O2 sensor wire and need to change it out to a screw in type for the downpipe. I have searched and learned that a 90+ 7M uses the same O2 sensor, so I just wanted to confirm if I can splice in this universal bosch O2 sensor...

I’ve been putting off doing a build thread for a while, but I figured its about time so I’ll start with a brief history I’ve always been a big Supra fan. This probably stemmed from my Dad who bought a silver MKII out of the showroom back in ’85 which he always raved about. After I got my...

Went to the dyno for the first time yesterday. I did two runs and the car seemed to be running really solid. Numbers were a little lower than expected at 271hp and 275 ft-lbs, but its a Mustang dyno so I hear that's fairly conservative. A/F's were pretty steady between 11-11.5. Anyways, on...

I'm thinking of buying Amsoil 5W-40 European Formula for my 1JZ. I've had good experiences using the Amsoil 10-30, but I figured the 5W-40 would be more suiting. Anyone used this oil or have any general comments about it? Thanks.

I did search with some success but still have a couple of questions. I know how to hook it up, but as for physically doing it i'm having some troubles. First of all is it absolutely necessary to take off the heat shield around the turbos to get at the right lines? If so what is the best way...

I'm looking to install a MBC and just want to confirm what size hose I should buy. I read 3.5 or 4mm somewhere I think. Thanks.

Does anyone know of a relationship between intake charge temperature and hp increase? Or a relationship between mass flow rate of the intake charge and power would also work. thanks.

Does anyone have a link for english instruction for installing the HKS speed limit defencer (type 1)? It's for a jza70 1jz.
