Happy Builder - New Engine Runs
sgraber - 21/7/08 at 03:48 PM

Six weeks after my back surgery I finally was able to spend a couple of hours tracing and attaching the engine harness of my JDM 20v Toyota Engine to my La Bala harness. Well yesterday was the first start. It runs great!

Once I blocked off all the open vacuum ports that I missed and connected the idle air circuit it sounds even better! The throttle response is immediate and OMG those velocity stacks make it sound like sex! It has a real sharp, crisp note like an 11:1 comp engine should. Love it! haha.

Glad to hear you are back in the garage Steve.

Cheers

Sounding good mate.

It's running on a megasquirt? If not how did you get it to run without the AFM/MAF?

Sounds terrific ... that car with scoot now ...

No my friendly alter ego, it's running on the stock 1998 Toyota ECU.

I've heard that there's maybe 5-10 extra hp to be found via extensive aftermarket tuning of this engine, but overall Toyota did an incredible job of wringing out every last possible ounce of performance out of the design.

The velocity stacks show a 7hp improvement over the stock airbox stacks. I still have to filter these, they are just for looks right now.


I'll be placing my Megasquirt and associated ignition and bits up for sale very soon.

Steve, it's all in the mapping with these engines. I have a bone stock silvertop in my striker running a aftermarket ecu and no airbox, the stock stacks are still on it.

I gained a shed load of torque low down buy altering the vvt switch point, and after that playing with the ingnition timing.

I have an Omex Technology 500 ecu on mine, stock showed 141hp Omex remapped nothing else changed has 163hp and 161nm torque from 2400 rpm all the way up to 6200rpm, redline is at 7800 at the moment but can be a little higher.

so there's quite some power left in these. even in the Blacktop.

Holy Crap. Those are some impressive numbers! The guys over on Club4AG.com and MR2OC.com would be very interested in hearing about that. How much dyno time did it take to get your engine into that tune?

I dont know if u heard of this before but, u shud add an oil cooler to ur 20V to protect the bottom end. At high revvs and high temps the oil starts frothing. The oil cooler helps keep the oil temp from reaching that point. Also try an oil catch tank, i think GREDDY parts has one on ebay.

I got the exhaust system fabricated this weekend. It's nice and quiet at idle, but the stacks provide a great soundtrack under revs.



I have an oil cooler that I'll be installing once I get the proper sandwich plate for the filter.

She moves under her own power now.

Happy day!
