I've heard mixed things about tech2s kit. It's the only complete kit I know of however...

Update:

Will be installing my AEM FIC this weekend tuning the engine a bit and defeating the top speed governor I'll try to get some more videos... should be fun once I tune it for 18psi!

Sketch, do you know which variety of JZ motor mount brackets you had? Were they the ones that came with the 1JZ? I ask because there are a variety of mounts (I found at least 4 at my local shop) to choose from.

Also, you need to take that thing to the track! I'd don't care about ET, but I'd like to see the trap speed and weight.

Also, what clearance issue caused you to decide to move the motor over?

Sketch_hs

The main clearance issue i had was with the steering rack.

I'm using the brackets that came with the engine. I modified the drivers side mount slightly to pull the pickup point a little further in to gain clearance

Just to clarify, you had an issue with some part of the rack itself, or the steering shaft?

Sketch_hs

Both. Subframe lowers rack, engine sits 1/4 inch or less above it.

Drivers engine mount very close to steering shaft, 1/4 inch again. Works great though, no contact.

Got it. Thanks.

Fan upgrade today. Stock toyota celica fans worked okay, but I wanted some additional clearance and some serious cooling power!

2 spal 12inch fans 1320 cfm each!

couldn't find an off the shelve fan shroud for my 94-99 celica radiator so I made one. Simple right? Darn thing took 4 hours to make! The circles for the fans are HAND CUT. I love my thermal dynamics plasma cutter but I really need the circle kit.

Results are great. Fan cycle for less than half the time! Idle dip is LESS than stock fans, thanks to the smooth start of the spals! AC is a bit cooler faster thanks to the additional airflow. Should have no issue in the Sacramento heat!

Painted and mounted


Hells yeah!

Be careful.

Just because you use fancy electric fans, doesn't mean you're providing the necessary CFM's to properly cool a 2JZ.

My shop actually told me I need something like 3,300+ CFM, which is also what this web-site suggests.

4 causes of 2jz-gte engine overheating, and some coolant boiling issues - Solid Thinking

On my 2JZ setup, I think we're going with some Porsche dual electric fans + shroud that pump something like 3,600 CFM's...I forget.

Sketch_hs

No issues in 106* Sacramento heat, AC on full blast (which is ice cold btw!) and back to back pulls doing road tuning.

I just don't have any more room for additional PULLER fans with the current setup. I do have a single spal pusher fan on the AC condenser that does 500 cfm also.

I could probably setup some pushers on the radiator if I need to improve it, but it's not had any issues at this time.

I'm considering adding the Spal fan controller to make the operation a little smoother. Right now I have them just running of a stock toyota fan switch and stock rx7 fan relays, with an interrupt for the AC (default open, open on fan circuit)

(SPAL USA)


Another note, once you are over 40-50mph proper air flow to the radiator and ducting should be a lot more important. This is difficult with a large front mount and ac condenser in front of the radiator though. If I was building a road racing only car I'd probably try to do a sidemount

nice work so far, the engine looks quite at home there.

Ok moving to another question ..hows the car on the freeway?

Sketch_hs

Man it's great! Hauls ***, rides very nice but has quick reflexes. No exhaust drone. I like it more than my supra....

Sketch_hs

Heres a pic of when i first got it:

charlie 7

Can't wait to start mine!!! =D

Sketch_hs

Took 120lbs of junk out of the car today.... Spare, tools, jack, and previous owners 2 12s and amp.

Drives noticeably better, and I don't miss the tremendous knock (aka dumb slaps) at all.

I love the stock turbo... the engine has great power and torque all over. The limit of the stock turbo is probably right around 350whp though. Tomei makes a nice drop in kit that will do 450 (crank?) with near stock spool. I've really been drooling over the new EFR turbos though, and have looked HARD at the 7163. It might happen in the future.

This car is so much lighter than my old supra, it doesn't really need as much power. Lately i've been working on the suspension and handling more than anything... got it pretty close.

I'm currently running 500f and 350r springs on the konis, not too low... pretty comfortable and finally handling really well. I've done 5 alignments to try out different camber, caster and toe settings and I think I'm finally happy.

Running about 1 degree front camber, 6 degrees caster, zero toe

Rear about 1.1 camber, smallest amount of toe in, nearly zero.

Front shocks at 90%, Rears around 60%

I had Koni's with Ground Control "Coil overs" on my Talon and I agree they ride and handle amazing.

Sketch_hs

Well I really had my heart set on a borg warner efr 7163 but looks like they wont be available till next summer! what to do what to do.....

Sketch_hs

Well I blew the stock turbo so I've been working on fitting a new unit. It's a Borg Warner EFR 7064.

Need to make some things better, especially the intake. Love the turbo though, the car is MUCH faster at 12 psi than at any boost the stock turbo could make. It spools a little slower, but doesn't feel laggy at all VS big turbo cars. Very fun to drive and responsive. Bought the turbo from Full Race. They are awesome and really hooked me up!

Some pics... Sorry the cam quality. I'll be reworking some parts of the setup and hopefully hit the dyno and see what the turbo will do at 20+ psi

I was originally thinking about the 6758 too, but the guys at Full Race talked me out of it. They said it would simply be too small and restrict the top end, much like the stock turbo.

The 7064 is very responsive. The car has a little less torque/power under 2500, but feels much better everywhere else. 17 psi easily comes by about 3k but positive pressure is everywhere. Above 4k the car is a rocket ship.... much more power at 12psi than the stock turbo any any boost.


The best part is part throttle and just driving around. The engine feels more linear and powerful.

Going one size up would be fine even on the 2.5 if you wanted a little more power. I imagine the 7064 on a 3.0 would spool crazy fast, maybe be too small.

I may switch to the divided t4 housing and a twin scroll manifold to match in the future.

BTW, I purchased the turbo and some bits to fit it from FULL RACE. They were awesome to work with and I received everything in just 4 days!





It's still on the stock ecu, but I'm using AEM FIC 6 to control fuel/timing. I can cap the MAF where ever I want and use the internal MAP sensor to tune. I'm maxing out the stock MAF at about 17 psi on this setup.

It's also possible to completely eliminate the MAF using AEM FIC, but it requires a bit of tuning. I've not gotten into that yet. I may also switch to a z32 MAF, as the other 1jz vvti guys seem to have good success with them.

Here is my first attempt at a trac delete throttle

I'm slowly getting better at welding aluminum

Sketch_hs

Setup change! Sold my 7064 to my buddy for his (my old) 1jz powered 280z

Now running a efr 7670! Twin scroll t4 with twin scroll manifold. Need to redo the intake setup... also planning on switching oil / water lines around.

I'm getting better at tig welding... still need more practice though!












Test drove it a little today. With wet roads, any boost equaled instant wheel spin! Will post again once it drys up...

Also got the cruise finally working... just had to fab up the cable!
