Just a joke, i've been wanting the Ti turbo for quite some time...

How exactly would a much lighter wheels and shaft not buy you quicker spoolup / recovery ?

 

Let's see...Here's my base run before tuning. Can you see the turbo spooling any later? No, it's linear with RPM. Don't waste your money.

Yeah, I think the differences are negligable for the cost.. However the Ti Turbo components make up the slight difference in spool incurred by the larger turbine housing.. Likely you won't notice much of a difference though.

 

If the Ti turbo would buy me full spool up at 3,000 RPM's I'd be into it

 

Again, it won't happen. I know you might want to and it is afterall, your car. The results will be no different from the graph I just showed you. What is the purpose behind your reasoning? Bragging rights? Enlighten me, please!

Let me refraise...it CAN happen, with tuning and cam timing. There is a cost for that. Increased cylinder pressures and increased probability of knock.

 

Its hard to say whether you'd get full spool for certain, my experience is close to that with the Ti turbo, 10.5 housing, O2 housing, and Tubular manifold.. Honestly I think the combination of components was just "right" for my intentions.. I don't know for sure if just the ti turbo and 10.5 housing would spool much different than stock.

 

WHOA! Jack and I are on the same page! LOL

 

Dude, you need to calm the fu©k down.

My reasoning is drivability, and the fact that I like anyone (I would assume) would like my turbo to spool up as soon as possible. More power, or even the same power at lower RPM's, I can see where that would suck

I don't know, maybe you are right. However if you are, I guess I don't exactly understand why.

 

Yeah, ultimately if you experiment with similar components, your results will be fairly similar.. eh? Your dead on about the cam timing, and cams in general with this turbo.. 264 cams, or stock with cam gears, minimal cam overlap, and advanced timing improve spool.. Only you end up losing high-rpm performance. The problem is with the reduced cam overlap and timing adjustments, you build quite a bit of cylinder pressure.. Since our engines are a bit noisy at lower RPM, it becomes a little difficult for the ECU or even a tuner to isolate knock from engine racket..


However, with that said, I must disclaim some of what I'm working on, a 2.32L short block, race ported head, 272 cams (leaning toward -3/-3 timing) since I'm making calculated changes based on my needs. The turbo isn't the entire equation in the performance and drivability of my car..

 

Calm down? Forget all about my advice...do what you want. You're going to do what you want anyway.

Also, watch your mouth or a mod might just hear you.

 

Wrong. I was installing the complete 105ti turbo. No kit came with mine! But I did get it for a good price.

 

*lol* maybe you are right about that too.

I never said that you were in no uncertain terms wrong.. I just said I don't know.
Just didn't care for your tone.

 

Really? HAHA No parts? Jeesh! Believe me, Smog, I've been right where you're standing. I wanted to pull my hair out. Did you purchase the turbo components from different sources?

 

*lol*... yea, that reminds me of mail away turbo kits from the 80's .... Complete turbo kit = turbocharger .......

ahhh... nothing like a 5 day weekend under a Miata's hood.

 

Really buddy, I'd just hate to see you waste 600 extra bucks when you could put that towards something else. I'd hate for anybody to make a purchase and regret it when in hindsite they gained nothing at all.
