Can't wait to get this 20G Green built and tuned...

Looking forward to the results - particularly since the HTA71 pricing has gone for a ball...

This is my FP54 turbo (20G TD06SL2R-9B) without antisurge cover to be an ultra street sleeper. It looks so much like stock IX turbo! I'll also build 20G on stock hotside to compare with 71hta with same tune.

Need to get chra balanced, but before that, I need to build the 71hta competitor. Time to order some parts.

2006EvoIXer I'm interested to see A. the power results on your FP54 turbo. Mostly looking to see how it "works" without a anti surge cover. B. see how the hotside copy holds up for you. Keep up the good work!!!

I don't expect surge problems with this turbo. The opening on both wheels are about the same size. The FP54 and this 20G TD06SL2R have similar specs. Cold side is 52.56mm and hot side is 54mm.

In theory, as long as hot side isn't smaller than cold, surge shouldn't be a problem.
71hta is 51.2mm cold with 49mm hot. This turbo is known to surge.
Red is good with 54.8mm cold and 58.8mm hot. But look at Black: 59.1mm cold & 58.8mm hot. It's almost balanced, so it could have minor surge problems.

Does having antisurge cover affect things? Maybe.

Antisurge is a short circuit of airflow. When turbo is boosting and engine isn't taking the air, bov will recirculate air to relieve the pressure buildup in intercooler pipes. But if surge is severe and bov isn't quick enough to respond correctly, we get surge where MAF air flows actually stops intermittently. This short circuit is cut in cover where it is at an inefficient angle and location to force flows to go that direction only when there is enough inefficiency in intercooler pipes. Antisurge covers are important to have to reduce the hammering on thrust collars and thrust plate (test by checking in/out shaft play).

Does it affect turbo performance? Maybe.

I believe you give up a little efficiency because I think some air will short circuit just because the openings are there.

Just my opinion from reading and picking Tyler's brains.

*Disclaimer: I reserve the right to revise my previous post if test results shows otherwise.

Just kidding. This will be interesting to test. This turbo is really similar to FP54, except there are minor differences. I won't reveal the differences because it may not make any real world differences (other than wasting some money).

Appreciate the detail that youíve put into your build and this thread. Iím interested to see the new fuel pump rewire with the solid state relays.

thanks buddy. I haven't found a solid state relay that has a Normally Closed setting. I'm trying to retain oem safety. I haven't given up yet, so hopefully, I'll run across one that is rated for over 20A continuous.

The equipment used by injector servicing companies is not capable of maintaining 43 psi with a 1650 cc/min injector. I've personally seen this with 1300 cc/min injectors. Did you follow up with the cleaning service or FIC?

That makes sense. RC Engineering cleaned my injectors. Maybe their max is 1400cc, which is what they reported to me.

That makes sense. RC Engineering cleaned my injectors. Maybe their max is 1400cc, which is what they reported to me. I just used it and I'm at about 60% IDC in my last tune to make 485 hp.

RC Engineering should have the equipment to give accurate numbers.
