Version 3: 2JZ HX40 NA-T

Where you get the plugs and terminals to make your harness?

since i already have teh 2.4mm hg on my car do you think it would be easy to swap out to the TT head gasket while in car?

 

[rtrdpenguin]

I ended up giving in and buying the AEM plug & pin kit that comes with plugs and terminals for specific ECUs. You can get the plugs from certain civics/integras but the local junkyard was dumb and wanted $5 a plug, and pins are ~.38 cents each and usually require a bulk order, so the AEM kit was the most reasonable route.

Easternbeaver.com is supplying me Sumitomo plugs/pins/seals just like the stock harness uses for the other end of the harness

what exhaust manifold are you using? did you get a t4 to t3 adapter? did i fit well? im looking for exhaust manifold for hx35 to fit
2jzge, was liiking at xtd manifold on ebay for around $140?

 

[rtrdpenguin]

Just some ebay T4 manifold. It was hard for me to find a T3 one.

Precision 6262 is here

Bushings are in

 

[IBoughtASupra]

Why a 6262? What's the power goal?

 

[Moy]

Let me know how the spool characteristics are on that one Marco

 

[1986.5supra_kid]

whats your Compression ratio?

 

[rtrdpenguin]

I want 400-450, with great response. Supposedly the journal bearing 6262 is comparable to a BB 35r in response but has a little more top end, so I decided to try one out since they're not toooo expensive.

I have a stock GE engine with a TT head gasket, so whatever that compression ratio is haha.

Out with the old:

Some spider shat muticolored shit all over our couch:

So I got some connectors and made a ton of diagrams:

And many hours later...

Fresh everything. Goodbye 22 year old wiring.

 

[IBoughtASupra]

I see a few GM sensor plugs.

American stuff is good for something.

 

[rtrdpenguin]

Yep, GM MAP and IAT. Weatherpack connectors are so flimsy feeling compared to Sumitomos.

Runs and drives again! It's so much better, and it isn't even professionally tuned yet. I have an appointment for the 31st at National Speed (can't wait!).

Also, new wheels come in today

 

[IBoughtASupra]

You will never beat a standalone that is tuned properly.

What map are you running, stock 2JZ?

Get rid of that zip tie on the power steering reservoir! It looks close but have you tried an N/A pump? The reservoir is on the pump and could fit but it's going to be close with the throttle body rotation mechanism in the way. I hate zip ties.

Keep it up!

 

[rtrdpenguin]

I started with a stock 2J map and have been tuning it for the past couple days. It's quite nice and smooth now, with decent AFRs. I'm afraid to mess with timing myself though, I'll leave that to National Speed.

The whole P/S system and PCV system hasn't been made yet. I'm running a temporary setup right now just so I can drive it (it's my daily driver again, sold my 4runner...).

also, four 17x10s and 295s do fit in one supra:

 

[suprakidd]

yea you'll be surprised what all you can fit in the back of a supra :love: but your na-t build looks awesome bro, im going na-t 2j for drifting too.. im also interested in seeing how that 6262? spools..

btw what suspension are you running?

 

[rtrdpenguin]

The 6262 will build boost pretty much on demand. I'm very happy with it!

I have Stance coilovers, and machined solid subframe bushings for the rear subframe. I also have Battle Version control arms in the rear.

For drifting, I'd invest in a differential that actually locks over anything else. The stock LSDs are all worn out and one tire fires are not fun.

 

[suprakidd]

are you running a after market diff?

 

[rtrdpenguin]

I used a kit from Weir Performance with a stronger spring and shims to bring the clearance down between the pinion gears inside. It's very aggressive though, doesn't really unlock ever haha. Almost a welded =\ If you have the cash I'd spring for a Cusco/Kaaz/etc
