Fast 102 lsxr t

Has anyone ran one of these bad boys on their LS swap? If so did it fit under the hood? I'm in the middle of a build and am not sure how much hood-intake clearance I'll have. Any input would be greatly appreciated.

Re: Fast 102 lsxr t

Yes, my white RS had a FAST LSXRT with 102TB for a while. It's a tight fit at the back and the angle of the snout on the intake causes so issues with the air intake tube. With hindsight we could have milled the back of the TB at an angle to reduce issues with the air tube. I'm willing to sell my LSXRT if your interested just PM at a very reasonable price.

I didn't have tuning resources to get the deliverability dialed in 100%. It made excellent with my 383 LS1's small 229/229 cam. 465 rwhp & 442 rwtq. Let me know if you have questions I will try to help.

Thanks for responding.

The few people that Ive found who ran these all report similar issues. Its pretty much a consensus that it's not worth the minor peak hp potential vs the lsxr. I've settled on the fast 92. Thanks for your input.
