I have a partial CL kit, but why CL over the others? If I was buying a complete kit (not that you're asking my opinion), I'd go with a
1. Chris Jones
2. Orient Express
3. MR Turbo,
4. Muzzy's,
5. ATP,
6. Cycle Logic
Velocity Racing???
Don't get me wrong! The fit and finish of the CL kit is top notch, but the turbo he uses is old old old. VF22 doesn't compete with the Garrett or even the (gasp) Turbonetics (Muzzy kit). The CL kit does seem to come the most complete, and you can get it for $4000 compared to $5000 for the others, but imo, the bigger more efficient turbos of the Chris Jones or Mr Turbo kits are worth it! Look at all the record setting zx14s, and they are all using Mr Turbo or Chris Jones setups.
Honestly, they are all good. But if you pull the trigger on the CL kit, here's the things to watch out for.
I've heard the tune from CL is iffy. Make sure to throw it on a dyno, and keep the boost under 7 psi on pump. IMO, I wouldn't go over 6 psi on pump.
The oil scavenge pump is prone to failing. I've heard (though I don't know if it's true) that he pump on the CL kit is a window washer fluid pump, so as you can imagine, the heat kills the pumps with regularity.
Lastly, watch for boost creep if you're running the internal wastegate. I chose to modify mine to accept an external, and all the other kits use externals. I believe CL offers the external as an option, and if you go with CL, I'd recommend the external gate.
I also heard through the grapevine that Velocity is offering a kit for $4000, so that's worth looking at. Additionally, Orient Express doesn't advertise it, but I did some asking around, and they sent me some pictures of their kit. WOW, if you can get them to make you a kit, they are freaking NICE!!!! They include an adams cut and boxed pan, Garrett GT30 turbo. Very very nice stuff.
Haha, good luck!
