New turbo T66


Clifton

Recommended Posts

Time for the T58 to find a new home. I'm going a little lower on the CR with a thicker MLS head gasket. With this and the h20/meth at hopefully 25 psi on pump gas I should be around 500 at the wheels :twisted: . It's a P trim .70 a/r. Got it cheap, just needed seals.

Heres'a comparison of the compressor wheels. 280ZX wheel, CT26, T66.

I didn't expect you'd get around to it so soon, wow. That's great. Let us know what you think after it's bolted on. I'm running a similar sized A/R T61. My intake manifold is about ready to be taken over to the welder, just waiting to finish up my 3 1/2" turbo flange lift from my header that wouldn't clear the larger turbo. Should all be bolted together and on the road within a couple weeks.

 

What machine work are you going to do to prep the surfaces for the MHG? Do you know of a shop near you that can do lapping? Thinking of purchasing the lapping tool from SONiC?

I have used MLS HG's on my L28 and they held fine without lapping. I even reused one. I know the 7M has a design flaw though. I had the head surfaced about 1 year ago when I changed the stem seals. The block has been untouched for 180K miles :( . I thought about lapping, but lapping a block in the car would be a pain. I'm just putting it in and bolting it on. The compression might be a little low with the 3mm so if it goes in a year I'll try a 2mm. If you are looking for a Cometic gasket for your 7M or anything, http://paradiseracing.com had the best prices.

What are you using for the meth/water? Kit, diy? What? I'm doing the same for next summer. I have some ideas on a cheapo progressive controller that controls pump speed off of a map, maf, tps, whatever you want.

That would be cool. Especially if yo pulled a signal and made it progressive with the maf signal. And maybe had a gain knob aswell.

It's a DIY kit. Kits cost $400. I have a little over $100 in mine with a higher PSI pump. I don't really need a progressive controller. I'm not using it for fuelling. I need it to control knock. With this turbo's trim and a/r full boost will be a little later than it is now. Probably 4K if I'm lucky. I will have enough airflow at the rpms that they will activate so it won't be to much. I have 2 nozzles. I will start with a 5 gpm at 12 psi and a 10 gpm at 18 psi. I have 2 other nozzles, a 3 and 15 gpm if I need to adjust. I have them on solinoids so there won't be a delay either. Having them come on earlier than 15 psi won't help as I can already run 18 on 91 oct.
