Intake Manifold

[cherplex]

Is anyone here using any aftermarket intake manifolds. And if so what gains have you seen.

I'm only aware of two the one from naperformance(shown on supra)

and the one from streetdynamics which is still being tested(shown on SC)

The one NAperformance sells is the DaveH manifold. Gains aren't that great on the manifold, you won't see much overall hp gain unless your pushing 800+rwhp.

The reason most people are buying it are just for looks. It rids of the ugly manifold and throttle body over the valve cover, and makes the whole engine bay 10x more clean.

and changing the plugs easier :fingersx:

Titan is working on one of their own also

^ This is true as well. :doh:

Are they making an na-t aftermarket intake manifold, or an n/a manifold?

I thought I heard of a company making an aftermarket manifold for the n/a supra, can't remember who though.

I thought I heard of a company making an aftermarket manifold for the n/a supra, can't remember who though.
according to Nero, it would work on both, but the n/a guys would have some piping to work out

That would be cool. Yeah, I'd assume some kind of new intake piping would be needed to fit where the new (or moved) throttle body would be.

from what i hear, the dave h manifold has a better flow then stock, and you have less(not much) heat soak which is a common problem on turbo cars(well all cars) I mean ya that isnt much, but it does do alot in the long run

I am using modified TT intake manifold with modified NA lower runners.

As for before and after gain, I have experienced noticeably quicker spool up, virtually no lag, no joke. In my previous set up, the lag was quite painful.

My car also idles smoother than when it was NA with absolutely no stalling issues.

im saving up for the virtual works manifold now its quite pricey but if your going to be making the power then its deffinatly worth it.

whats involved with making the TT manifold fit?

With a nice FMIC and good air induction into the motor you won't be experiencing heat problems. Like said above.... a car with 600, 700, or 800+rwhp this type of application will come into play and results will be seen. I'm not saying you won't pickup a slight powergain by using this part on a low-boost application, but it's def not something that you need to keep your setup running strong.

whats involved with making the TT manifold fit?Well it simply doesn't fit, as far as I know the bolts don't line up. It would take some custom work to get it to fit, and IMO you're better off picking up a custom intake manifold already made for the GE.

It required custom of fabrication. It actually would bolt onto the NA lower runners, plug and play, but the openings between the runners does not line up, which will cause major restriction, poor performance.

To get it to work correctly, you will need port polish like crazy, adding/welding additional materials for additional support. It is much easier to get the DaveH manifold, Accufab TB.

I am using NA TB, the TT throttle body actually should work fine. I had the TT throttle body on the car before we switched back to the NA TB.

I had some problems that was casued by the ARP headstud washer, originally we could not figure out the problem so we took the TT throttle body off and put the NA throttle body back. As sad as you can imagine. This move was necessary.

With the TT style intake mani, it require 70% less IC pipings from FMIC outlet to throttle body, less piping can't be bad.

Also the intercooled air is now travel through cooler side of engine bay instead of hot side,

You can also pop your hood and confuse people that you have a TT motor with a distributor, as Jason (supra4ever) did at the south bay meet.

Or you can make your own with rolled sheet metal.


Hey has anybody thought of independent throttle bodies? I mean don't flame me but the Nissan RB26 has ITB's on a twin turbo inline 6 which gives it a monster linear power curve. I think one could get a way with using 2 ITB assemblies from a Triumph Speed Triple and then making custom flanges for it as well as lengthening or shortening the runner for proper fit then modify existing TT, Titan, StreetDynamics, or your own custom manifold.

Just some thoughts of what you might wanna consider.

Ok flame on you human torches :)
