20B or single turbo?

Well, as soon as i get my car fixed (believe it is a bad fuel pump (which was the denso 500 - so i was upgrading anyway.....)) I want to do one of two things:::

BIG single turbo kit
racing beat side skirts
a 50 shot of dry nos (zex- head great things)
a supra wing (yeah, yeah, yeah. i like em, okay!)
bigger fueal pump (the denso 500 might not be big enough)
1300cc secondaries (anyone know where i can find em without a core exchage?)

OR

20B Engine

Can i run a stock twin non-seq on a 30b (don't think so becuase of mainfold, but....)

How much would a 20B and a manifold with a single turbo cost? I can do the labor.

Call up www.alamorotary.com and let them know you can do the labor. They could use a skilled hand I bet :o

dude you guys are mean yeah...a 20B is kind of hard to come by...the only one i have seen a price put on is is Peter Farrell's 3-rotor...tested at $83,588 (i'm sure that is just the car...not the labor lol). so unless you got the means ($$$$$$$$$), do the turbo.

Lets see single turbo kit $8K roughly.

20b conversion ~$40K through Pettit.

Your choice, I wish I had that kind of money.

No brainer... 20B With the turbo. If I can afford the 20B why not throw some icing on the cake.

20B PP huge huge turbo...

Seriously 13B with single turbo if you want to keep the price under 15k...

20B with either non-seq converted or big single if you don't mind spending 25k++

thanks for those of you who posted later. Those earlier (the mean ones) can burn in hell . . j/k.

but really.

No, anyway. Thanks. I think I'll go with a big T88 turbo. I found a pretty good deal on a T88 and some 1300cc secondaries, a supra pump and some body goodies (rb sideskirts, a feed hood, and a naca duct and some vents for the hood) for around $5k, so I'm going to jump on it......

Hmmm....

Single Turbo Kit - $5,000-$10,000

20B conversion by Pettit, Alamo, or any other shop that are able to - $26,000-$35,000

Handing those V8 lovers their @$$#S to them with either setup - priceless

For everything else, theres Visa mastercard.

Supra fuel pump? Try a cosmo fuel pump, it seems to work for some guys.

Before you get a BIG *** turbo, think about the realities of performance with those. I heard that a T-78 doesn't spool up until about 3500 RPMs, and a T-88 wouldn't get up to speed until after that. Basically, you are going to be N/A for half of the powerband (so I understand). I have heard that the GT35/40 is a great overall single turbo, or you might want to look into the new twin setup that RX7store offers (A-spec?). Just a thought...and don't forget about the ECU, FMIC, BOV, Boost controller, etc. that go along with it, if you haven't already

It's not just being NA when your are off boost. The turbo may cause backpressure giving you vacuum

I think you need to do some more research on what you plan to do, 1300 secondaries w/ a Supra fuel pump is truly a weenie fuel system for a T88 unless you only want to run 10psi on that bad boy. And I think you should consider some other goodies rather than body parts to accomodate that single turbo setup (clutch, big fuel system, programmable ECU, gauges, fmic). You are looking at closer to 8k for everything you would need.
