Dont tell Peter, or other big turbo haters that. They think that we are 5 hp briggs and straton motors untill it gets up on boost. It is funny because I have the stock URQ boost gauge in my cluster, and I can get the needle in between the dots that signifies stock PSI at 3400. That is basically where the stock k26 spools.

Like Jim told me, at 15psi, he was walking 95% of eerything at Spring Mountain, including r8's. I am pretty confident he could run 5 psi and walk any 7a, 20vt, and any 3.6 v8.

Jim, that vid is sweet. The audio is great. You can hear the wastegate dumping boost, almost to the strum of your logged PSI levels. Very cool

Thanks guys, this is a good turbo no doubt about it, but after riding in a few 3071'd ur-q's around the track, I want something that is closer in spool to the 3071. I spent the better part of last night on the internets and it you really have to push the HTA turbo's to get the extra flow. So the HTA 35R still puts me in that 30+ psi range that I feel is unceccessary. I want to take this exact dyno plot and move it down 1000 rpms :)

If anyone wants a dyno comparison of a particular turbo, I will be up for putting it on the car and doing a baseline if you split the dyno/fab costs with me. An HTA 3076 or PTE 5857 will make it onto this car in the next two months.

I was just looking through my thread and found this, lol. Stock JT motor vs my car.

Walk may be a bit much, on 15 psi it was pretty even :wink: I was a nice driver and let them pass almost every time because let's face it, R8>90tq in the corners, there I said it.

I think Javad should hit you up on that offer and let you barrow a 5857. :)

I may be interested in a baseline with my setup. Maybe I will build my header and downpipe, send it to you and have you throw it on your car with a hta35r. That doesnt seem like it would be that hard...

Janis, I seem to recall then topping out at 53C.

So I found a DSY 6-speed to swap in while I am doing some other work on the car :) There was a conversation about the alignment dowels a while back. It looks like you can only use one of them on the 5 cyl.

The old seats must have put my Dad's left leg to sleep, rendering him unable to compress the clutch. :wink:

Minus das quattro!

Here are the only stock drivetrain parts left on the car. I am pretty sure the rear control arm bushings and and subframe bushings are factory. 230,000 miles later and a steady flow of boxes from 034 will finally give them a rest.

The subframe is cracked as usual and both axles are bent. :lol:

Going on the car:
New CV boots and two strait axles thanks to Yoda
034 Delrin CA bushings
034 Aluminum SF bushings
034 Rear tie rods
034 Ball joints
034 Density rear diff mounts
016 shifter bushing :D

Nate, glad to hear it makes a difference. I also installed new wheel bearings. The originals were surprisingly smooth still!

Jim:
Did you seam weld the rear control arms?
I've seen two failures of the stamped rear control arms - both had delrin bushings.

Did you do anything special bushing or sleeves?

Control arms are now seam welded and the SF is seam welded in the area where it cracks. Paint is drying, hopefully the control arms did not warp, or I will be forced to invest in a huge vice and BFH.

There will always be the giant dent in the rocker panel from the snowbank in Steamboat that I can fix.
