I want to first state what I would want out of my ideal turbo car. I want something that is quick (low 13s-high 12s down the 1320), fairly high boosted (16-18psi) and also highly streetable, for example, something that I can take to school and the track with.

What is the difference between both wastegates? Why is the tial way more superior as compared to the deltage? And would a tial wastgate be necessary to reach my goal? I also am looking into acquiring a BB det and running a similar setup as Louis Anaya but not planning to be so extreme. I would be jus happy hitting high 12s all day.

Thanks,
Chris Alfonso

Let me make an attemp to answer this

pretty simple from what I heard. The deltagate wastegate allows boost creep after 10-ish psi (don't quote me on this). Its not able to bypass enough gases around the turbine if you go higher than 10-ish psi. The tial is able to bypass gases much better than the deltagate on higher boost levels. Ok guys, tell me if I got this totally wrong?

Deltagate sucks. It's cheap and you get what you pay for. Boost creep and failure.

TiAl is the ****, HKS a close second.

TiAl is used on LeMans turbo cars. I don't mean that TiAl custom makes wastegates for LeMans cars.... I mean, the same TiAl WG you go out and buy is the same one that the LeMans guys use.

If *ANY*, and I mean *ANY* part can survive LeMans, it is a top rate part. You will *NOT* break it on your street car.

I recently rebuilt my Deltagate since it wasn't working properly. This was the same Deltagate that came off of my burned 1993 Sentra SE-R. The diaphram and spring were tweeked from the fire. I have not had one problem with the Deltagate other than this one. I have seen diaphrams deteriorate because of heat almost every time. The only apparent reason that most people get the Deltagate is price. $159.00 Deltagate -vs- $350.00 Tial. You choose! Both Ben Benavides and myself have used the Deltagate wastegate and they have worked for US. I have never had an overboost problem with my Deltagate. I have a 7-9 psi spring and it regulates boost @ .5 bar all the time. Don't get me wrong, Tials are very nice units, but the Deltagate has been an inexpensive alternative to the high dollar wastegates on the market for a long time. Even if they do need to be rebuilt, the spring usually runs $8.00 and the diaphram is $22.00. Like Jay said, "you get what you pay for", but the Deltagate isn't as bad as some people make them out to be.

Yea maybe I should not have been so harsh on the Deltagate, I know a lot of people use them. That seems to be all the GN guys use.

It's obviously not up to the quality of a TiAl but for the money I suppose it's better than a ported internal gate.
