Update on Paul Carey UZFE powered Drag Car

[Lextreme II]

Just got some new pictures from Paul Carey. His car is almost done. I supplied the 2uzfe shortblock and he supplied everything else. He has lots of custom parts and will be breaking some records. Here are some pictures....

The FB is such a great drag platform. Easily swappable rearends with solid axles with a range from 9 inch to 8.8s out of ford 5.0s (like I did with mine). I had a ford turbocoupe 2.3T converted to 16 valve volvo cyl head and a t3/t4 turbo. Thing hauled but i'm not a big dragger and wanted to go with an IRS setup so I baught my MKII supra =).

Can you imagine this car in your rearview mirror?

beautiful..

First pass in the blown 2UZFE hybrid

Well we finally got to the the drag strip, and gave the new blown alky 2UZFE a run.

Short report and photos
http://www.aeromanagement.com.au/racing/outlaw_news.html

This motor uses a 2UZFE steel block from Lextreme, the four bolt Lextreme conversion, and 1UZFE crank and heads.

...and believe me - it's a monster. We will be back out in a month or so to complete some full passes.

Paul,

You are the man.... I feel so honor that you gave me a chance to serve you. Its just Awesome..... Please give us more info.... and I am drooling....

I can see how awesome this monster really is by looking at the background. Spectators are plugging there hears.

Why does it use a 1uzfe crank and heads? Do those differ from the 2uz?

 

[SC400TT]

Awesome!!! UZFE Power!!!!!!!!!!:boggled:

The 2UZFE heads and crank are different, but not readily available here in Oz, and cams and manifolds are here off the shelf. That is the main reason for using this combo - as drag racing tends to use parts up pretty quick.

Will have detailed info later on the under bucket shim conversion we did using off the shelf RB26 Nissan parts that fit in.

[Lextreme II]

Wow..... 1,200 hp and 10,000 rpm..... Those specs just trigged my drooling reflex.... Few buckets please.....

I'd be interested to hear about this shim under bucket, especially if you can run high lift cams (13mm) without any special race coatings

What is the lift/duration of the cams you are using if you don't mind giving out that info, or at least info enough to disclose what type of base pressure/area your buckets are receiving? Do the nissan parts have special coatings on them or anything? I hope those parts will fit a 2uz head as well!

The 2UZFE heads and crank are different, but not readily available here in Oz, and cams and manifolds are here off the shelf. That is the main reason for using this combo - as drag racing tends to use parts up pretty quick.

Damn that makes me like the U series engines that much more, wow- I can only imagine what the new 5.7 will be capable of (or what can be cross matched parts wise)

 

[AeroPC]

Our application is racing obviously. We run .470" lift with 320 degrees duration, 2UZFE buckets and 100 lb Crow single race springs.
I used the RB26 valve spring retainers because the 2UZFE retainers are too small in diameter (2UZFE springs are much smaller than 1UZFE) and did not fit the Crow springs. The RB26 retainers fit perfectly and were cheap and on the shelf at the local Nissan dealer. When we went to assemble the valves, we found the 1UZFE collets placed the retainer at the wrong height - RB26 collets fixed that. Interestingly we tried the RB26 bucket in the hole - and it fits exactly (and has a larger area under the bucket in the boss area for the shim). We had to mill .040" out of the spring base area, because the springs coil bound .020" after max lift (.060" recommended). With custom made shims the assembly went together nicely - although we do not run valve seals. You would have to check that clearance first. With only one run on the engine, we will be watching these details and wear patterns closely.

What is the latest on the 5.7 engine - is that coming out? I would love those extra cubes.

Paul,

Good stuff, When are you running next?

 

[Lextreme II]

Paul,

Thanks for listing my name and our site on your spec sheet. Very honored.

 

[AeroPC]

No worries Davo - it was your idea on the 2UZFE steel block that got me going, and the info and parts supply is great.

Thanks PC

Thank you for your reply,

I have heard from various sources that the 2uz buckets should be replaced when running a high lift cam, my cam of choice is to be something with 13mm of lift and 265 degrees of duration. I was told this is too much for the stock shims/buckets and that the base area is not large enough.

My car is a street car and will have valve seals, so I appreciate that advice!

Do you feel this nissan hybrid setup can withstand the cam I listed above with the proper nose pressure? I forget the diameter of the bucket (maybe 33mm?) , but I don't want to have to machine it for a larger bucket ... what do you think?

Looks like our experiment with the 2UZFE block in blown alky trim did not pass muster. Huge 3 inch crack around No 4 main in the block. The area is a little weak and thin to continue with this idea.
We are now making plans to CNC a billet 2UZFE block (no cooling) with 6 bolt mains that is super strong (2,000hp with 60lb boost) from 6061 T6 ally.
Will keep you all informed.
