91-92 Diablo vs 94 TR

Did my Newman diff replacement my self for less than above. But only the diff replacement would have been less. I rebuilt gearbox which included 1st and 2nd gears with diff. So my part cost was more. But now all the problem areas of my TR are taken care of. Beware of a noisy 1st gear when you test drive a TR for purchase.

 

Replacing the diff. as a precaution. Noticed draining trans oil, broken gear teeth. Necitated completely rebuilding gearbox. 1st gear was noisy, but shifted fine. Good to repair when I did, further damage was going to happen.

 

I have tubi loud with tubi down pipes on my 98 Diablo sv. On my 512tr I have a custom made capristo exhaust I think with custom made downpipes.

The Diablo sounds insane. At high revs it has an amazing howl to it. The 512tr sounds more brute and bassier.

I run no cats, tubi precats and ansa exhaust on the TR; it is loud, crackles and sounds like an old f1car.
Capristo are awesome.
If money is not an object i would go Kreissieg.
Those cars are old, don’t expext the claim hp gains, mostly sound and throttle response although Capristo on a TR will claim 40bhp gain...

What are Tubi precats? Precat bypasses?

 

He either means tubi hiflow cats or tubi test pipes

I didn’t know tubi made bypasses

 

I'm not sure they made hiflow cats but they definitely make test pipes. I have test pipes on my 355.

I have both a QuikSilver exhaust (no muffler) and secondary cat bypass (need the primary for inspection in Houston). I have always thought tunes for non-turbo cars are silly..."Gains of 15 HP" the ads shout....yeah, but only over a narrow RPM range.

 

304SS.....non-turbo cars don't get all that hot....had to wrap my modified Porsche Turbo though.

 

who told you or from where do you know this? can not believe this increasement

 

As i mentioned my freund i do not believe auch but its on capristo’s website, go on the TR section and they have a video of a dyno to back up their claims. Capristo is a german company right? So maybe they are not lying

they say something about 30 HP, not 40,
here is the link to the dynotest:

but all exhausts are not street legal

 

Never do an exhaust on a naturally aspirated car for HP. You won't feel a difference. Only do it for the sound/heat improvement

yes agreed that was my point

 

Well i live in the US and the TR was 10hp less here which is where we have our discrepancy

They are called pre cats.at least ots what eurospares call them in their catalogue
The test pipes are the actual cats. In my opinion they help the sound but thats about it. The precats are a pretty poor design which inhibit the hp; they are one of the reasons the euro tr were 10hp more powerful. Stupid US regulation
Note that the earliest TR had nothing at all in europe and were the more powerful stock ones.
