Just finished testing new Intake manifold with great results

[SilentHill]

I'm interested in this as i have Rotrex charger so i use the standard inlet manifod for my SC car with 270+ HP... i'd be interested to see what a new Inlet would give me if it's making 20 HP on the stock NA!

Considering the entry-level supercharger are around 220hp that would be an awesome alternative to FI.

except for the not unimportant matter of torque.

Much depends on what rpm range in which one would be driving, and the power/tq curves.

Any luck with dealing with the Kold-Fire guys?

I have attempted to contact Charlie via PM and Message on Moremonkey as well as through Ronin with no response. I'm a patient guy, but my patience has limits.

I've also signed on as a dealer for a next gen standalone system, so I may just build a patch harness for those if this stock ECU tuning nonsense gets to be too much of a PITA.

Does this work with the Exige S?

nope, your intake manifold is integral with the s/c.



I don't know if DD performance is making these anymore, I didn't see it listed on their website. I'd love to do this over a S/C setup.

[mattjk]

actually, I would really like to do an ITB setup. I had one on my AE86 Corolla. made an extra 42rwhp on the dyno with some mild cams.



Love the sound too!

Only problem is converting the fuel injection to MAP based. I wonder is an HKS VPC can be retrofitted?

found this. 227 whp n/a 1.8 litre 10k rpm toyota 2zz-ge - NASIOC

latest is they made 227rwhp on an elise, but the motor is fully built with 14:1 compression.

while good, it's disappointing considering a k20 will make 250whp with less effort.

btw, I'm guessing the OP is not on here anymore because "they" wanted him to pay vendor fees.

I don't think "dispppointing" is the word I would use for an engine that makes 148 hp/litre.

you're absolutely right, about 6 years ago.

read up on the honda k series motor and what they are doing to those, with stock internals.

[Ali.M]

Oh man, 148 hp/liter?

What about 400 or so hp/liter from F1 cars.

[shay2nak]

that is sleepless' motor. He's got a long ass thread up here about it.

[Genomaxter]

The highest I have ever heard a K20 has ever made NA is 270hp. That is a K20, not a K24. K24 get 320+ hp NA. So being .2 L under a K20, the 2zz is doing fine especially with the very limited aftermarket. There are no companies backing up Toyota motors that arnt 15+ years old. So if performance is to be made, its by people with time and money to experiment.

Im an absolute fan of the K20 (not K24) but I see merit in doing what hasnt been done before instead of going with mass market appeal. To me if I go beyond 2.0L, i'd rather have a low liter v6.

We're still SOL for a tuning solution. Kold Fire was a bust - they wanted to send us an ECU, have us dyno it, send the ecu back with "suggestion" and rinse and repeat. Apparently their tuner is in Europe somewhere. Thats no way to try and to try and tune a car. And Charlie is playing the invisible man still so we're kind of scratching our heads for an ECU solution. We could dyno it on a stock setup, but with the runners being as short as they are I don't expect it to do much without some revs to take advantage of the high torque peak.

It would be awesome in a Turbo car though.

No posts in 2 years? Is the lotus project dead? I am really interested in this manifold if it was ever produced. I don't see it on the DD website. :-(

Sorry! We stay so busy that its really hard to keep up with all the forums. We built a new facility and moved into it last year and we have been busy growing steadily since then.

We actually just recenty produced an intake manifold for a customer with a built 2ZZ Lotus over in England : )

Here is a link to a thread the customer just posted on our forum a few days ago:

And a link to a supercharged Exige thread on our discussion forum from a while back that was pretty cool for good measure:

This looks good, but, given the other mods to this particular engine, how can we determine the effect of just the intake manifold and throttle body?

You can't really say for sure since there is not a "direct" before and after. All you can do is look at other engines with similar mods and analyze the torque curve and total power.

It makes good power up top on heavily modified motors when properly tuned - that is my only promise with regards to this short runner manifold. Which if you note the power NOT falling off as normal at higher revs, I am sure you will agree is obvious.

I may have an opprotunity to bolt a similar one up to a built 2ZZ in a Celica in a month or so. It is a fully built NA motor, and since the manifold is on the front I can probably do stock vs long runner vs short runner without much trouble.

Nah - I went away more because I was busy as hell moving to a new facility, and since at the time there was no good standalone option. The manifold needs bigger injectors and a bigger intake pipe, and cams and porting and header to be really worthwhile, so its useless if you can't tune for it.

Nowadays there are tuning options so it is worth pursuing.

If you keep an eye on our discussion forum on our website we should have tuning results for 3 different 1.8L 12.3:1 NA 2ZZs with intake manifolds in the next month or so. It should give us a good idea of the differences between the motors.

Just finished dyno testing out a 2ZZ swapped spyder with pretty much the same manifold - 214 was our best

For those of you who have been following Kortik's build over on our forums:

DD Performance Research • Forum

We finally got the car strapped down on the dyno got about 50 miles in for break-in, changed out the oil (still on conventional during the remaining break-in) and put another 100 miles or so on the car. Started tuning and we had some great results.

93 octane pump gas:

Runfile 048 - Full PPE exhaust
Runfile 060 - open header (unbolted ppe midpipe from header - no tuning changes)
Runfile 003 - stock elise for stock 2zz comparison.




Relevant -power -mod list:

DDPR Ported & polished head
DDPR short runner intake manifold
DDPR 80 mm cnc throttle body
DDPR 3" intake
PPE header, PPE catless midpipe, PPE muffler
MWR alternator & water pump pulleys
Circutworx oilpump gearset
Full Ferrea valve train (valves, springs, retainers, keepers)
Piper stage 3 cams
Mahle 12.3:1 pistons
Crower rods
MWR ACL coated main/rod bearings
Lotus 440cc injectors
Fidanza flywheel
ACT clutch
Apexi PFC - DDPR tuned

Since we determined the PPE midpipe & muffler to be a large restriction for this set up, we will be building a new free flowing exhaust for kortik and re-tuning.

We hope to pick up a few more ponies after some more engine break-in and switching to full synthetic. The engine currently has 180 or so miles on it.
