Dyno results: MWR 2ZZ turbo kit

[monkeywrench]

We ran some more dyno testing on our 2ZZ turbo kit this week to further improve the tune and to test a small design change. Numbers are about the same as the first round of testing which never got posted. Here they are:






Boost adjustments were made mechanically using the adjustable wastegate rod (standard) so boost level listed is the boost at the end of the pull. Through the midrange it's down 1-2 psi from that level. Add a boost controller and you'll have even stronger midrange boost at the pressures listed. We are recommending that customers keep boost at 7psi for 91 octane and 8-9psi for 93 octane for daily use but if you're willing to push the limits you can run a bit higher. We've run even higher than the 11psi you see above on 93 octane with a careful tune. Obviously if you've got a built engine the sky is the limit.

All testing was done on our shop MR2-S which has a high mile stock 2ZZ engine swapped in to it. The turbo kit is just our off the shelf unit which in Spyder trim means it's breathing through a very civilized chambered 2.5" muffler. Results in the Celica are similar. As with the custom systems we've been building for years these kits make outstanding power per psi which lets you run low safe boost on the street while still making great power. Specify the GT28RS and you've got 9-10psi of boost at 2500rpm.

standard disclaimers: the torque curves are actually very flat and just look like they rise and fall a lot because of the tight scale. The curves don't cross at 5252 because of the different scales they're on.

Looks about like that except we've moved the BOV to the passenger side so there's room for the oil cooler kit we now offer.

It's tough to see much on the Celica. It looks stock from the top.

I'll get pics of the 2ZZ MR2-S soon.

Just to clarify, that's the GT2860RS? With the 0.86 A/R turbine housing?

[Punkers7465]

were all of the dyno's done with just the 630 cc injectors? In other words you didnt have an after market fuel rail or something like a return fuel setup?

Impressive looking dyno's btw!

[GTsRasta]

Very Niceeeee!!!

[yankee_gts]

Nice Work like always

They shouldn't necessarily need it at 11 psi. The big thing is differential pressure. If you run low boost, the need to a 1:1 regulator in the return line is lessened.

[TRlPPlN]

when you say high mileage engine are we talking about 130 +??

[Entranced]

wow, great numbers! what type of turbo is that with and what differences besides boost psi can we assume we'd get with the GT28RS instead of what you have now? higher mid range, lower top end?

Price range and availability for the GTS, and what the kit comes with? =)

so interested.

A good turbo kit has an excellent exhaust manifold....any pics of yours?

[oONoGoAutoOo]

nice indeed

[Ch33z]

Your car is slow according to Memphizzzzzzzzzzz???

Personally owned by regular everyday people who don't own shops..

[Entranced]

he's just stating that there are more "fast" honda's out there than MWR's shop car. Granted, It's a much larger market base with engine swaps involved.

The graphs are actually the GT2871R 0.86. I re-ran the GT28RS last night, it's slightly lower on the top end but 10psi at 2500rpm sure is nice compared to the GT2871R's 4psi.

This Spyder's setup, 630's and stock FPR, are maxed around 330whp. To run at 330+ you need either bigger injectors or our FPR kit. We can substitute 750cc or even larger injectors in the kit for those looking fo high power. Personally I'd probably stick with the 630's and add the FPR for best drivability.

Thanks!

122k when it went in I believe. It was a misshift engine that we just put replacement used stock valves in. Despite the horriffic sludge inside from oil change neglect (previous owner) the engine runs tip top now.

The 28RS is still pretty efficient at the 325whp range and we made 340whp with it last night. Because of its efficiency the 2871R does make a bit more power at the same boost level. The 28RS of course spools quicker especially at low RPM but I'd by no means call the 2871R laggy.

Kits are shipping now and there is no price difference with the different turbo options.

Sure there are. Our car has only been down the track a few times. We're in uncharted territory right now and so far haven't found a transmission combination that can both get off the line and stay together with 670+ whp and a 2650lb (race weight) car. That's a tall order but we're working on it. One thing we've never had any trouble with is the engine in that car. Runs like a dream and makes crazy power. It's nothing fancy and we've made no changes at all to it since the first time it went together. If we can find a transmission that is up to the task we'll make MUCH more power with a larger turbo.

So far I'm very happy with that car's performance especially considering it was built for NDRA's Power Street class which is extremely restrictive and usually full of 11-13 second cars.

Can we see the 28RS dyno's? I'm curious as to how it compares graphically to the 2871R...

[shakey1378]

i know this is probably a stupid question but can this kit pass emissions,im guessing using greddy emanage ultimate you may be able to get the car thru obd2 emissions testing. been planning to turbo my car for some time but i dont want to deal with the having to buy a sticker rather than just pass thru. if i kept my car n/a it would be no big deal to swap in factory ecu for inspection but running a turbo is not a option with just factory ecu. please correct me if im wrong this has been eating at me for a while with njdmv nazi's

[Punkers7465]

couldn't you just leave the wastegate open (ie run zero boost) and put the stock ecu back in for a day to pass? Assuming of course that you left the cat in etc. Someone correct me if I'm wrong....

Depends on location. It definitely won't pass in Cali, no turbo system will.

new jersey- they plug in my car using the serial port under the dash.
any idea as to best ecu to pass this test

Stock ECU would have to be in place. Running a piggyback on a turbo GTS is not a good idea so I'd personally run the PFC then swap back to stock ECU and injectors for testing. You'll need to add a 2nd O2 bung to the exhaust after the cat for the stock ECU to be happy.

[shakey1378]

oh ok so swap ecu back, injectors back, would you have to lower the boost setting as well as to not grenade the engine due to a lean condition.

sorry for so many questions. i just want to cover all bases and this turbo kit seems to be the best option for a stock motor to make good power. i plan on running the kit at low psi till i can afford to have mahle pistons installed...

You'd have to completely keep your foot out of it and not run any boost at all.

[steveox]

Shakey - I'm going through the same ordeal as you right now - except I have the air injection so basically there is no way for me to pass by removing the system. I'm currently running on an emanage blue without any CELs other than the removed air injection system...

As I work things out I'm planning on possibly upgrading to the PFC and keeping the blue for when I need to pass inspection.

certainly not impossible id only have to drive the car long enough for the obd2 to system to become ready and pass the testing then swap back asap. i may wait till i move to florida who knows

[GTsRasta]

Dustylax (spoolin spyder here) and friendofspyder over at spyderchat.com have emanage tunes just for emissions, and then swap back in their PFC's for the rest of the year. Contact www.nolimitmotorsport.com, and just take a trip out here to Long Island to get yourself an emanage tune that can pass inspections. That way, you don't have to change out the injectors and uncouple your intercooler piping to stick in your stock ECU when you want to pass emissions again. Much simpler solution IMO.

[Boosted2.0]

People always make such a big deal out of emissions with a turbo. If you are running a Power FC its the simplest thing in the world. Buy a used AEM gen 2CAI. disconnect and remove the charge pipe from the intercooler and swap the MAF into the AEM CAI. plug in the stock ECU and injectors and go pass emissions. Its that simple.

you guys are awesome, if i had a credit card i would currently be going for broke

What trim compressor? There's a pretty profound difference between the 48 trim and the 56 trim in how much air they will flow.

Careful with the generalizations. There is a pretty huge difference between a 48 trim, 0.64 A/R and 56 trim, 0.86 A/R model, both commonly referred to as "GT2871R".

I've kept my stock airbox around for just such an event. I can make my car pass emissions in about an hour and a half.

My year is a bit different though with the air injection. They don't make turbo manifolds with it, and you will get a CEL without it. Not sure if the 04 celica's are the same as the matrix and corolla... If it weren't for that I would have no issues at all...

If you floor it though you may overspin and explode the turbo. It's got no resistance on the compressor side and the wastegate will never open.

56 trim on this test but we can supply either upon request.

I would say "The 28RS is still pretty efficient at the 325whp range and we made 340whp with it last night. Because of its efficiency the 2871R does make a bit more power at the same boost level. The 28RS of course spools quicker especially at low RPM but I'd by no means call the 2871R laggy" applies to both GT2871R models and is a valid generalization. Both models have more lag than a GT28RS and both are more efficient in the 325+ whp range.
