All right you all know I am planning to turbo my car, the problem is which kit to get. I see this question a lot asked on here everyone told me and from what I saw was c2power, but then yesterday I saw a new one which someone mentioned, which is the haas kit. The Haas kit or the c2 power don't know which to choose, maybe you all can help. here are the 2 different letters I have recieved first c2power::

What I suggest is the max power that till cost efficient. Thats st2 turbo kit.
The parts that you will need:
base turbo kit 3590$ but need to specifi you need bigger injectors (550cc) compared the 380cc ones that we suply (price is the same and included in the base price)
wiseco pistons 500$
crower rods 750$
RPS max (blue pressure plate) or similar clutch 390$
You can run this setup safely at 14 psi that is putting you around 280whp (320bhp). I would not go any higher as daily. Please understand that going for any (daily) higher whp numbers will seriously increase your costs.
The setup can support ~330whp and you can use it on your own risk on any higher boost setting.
optional parts
gt28rs turbo+300$
large IC +200$

delivery is usually 1 week after we recieved payment as UPS ships 3-5 days. Shipping of the base kit is 290$ to the US.
For install advices please visit nc.org and ask in the forced induction forum. We are not close ( we are in the EU) enough to advice an installer in your area.
Thanx

All right first of all I won't need the clutch because I am an auto. Now here is the letter I recieved today from Haas:

Our turbo kit for the Celica GT only comes as a "Stage-II" as we only offer the non intercooled system for the MR2 Spyder. The Celica GT kit also comes with the GT28RS turbo which we have run up past 15psi on the stock 1Z...I don't recommend you do that with your car, I am just answering your question about max psi. Basically the turbo can flow more than the engine can hold if you want it too. We are at about 330whp with our shop car. We can also upgrade the turbo to the GT2871R if you plan on building the motor and want to make over 350whp but as it sits the kit will support about 330whp.

For the auto trans I recommend talking to Level10 out of NJ. They can put together a whole package for you. I would not recommend building your trans yourself, take it to someone who knows them inside and out. You CAN install the turbo kit yourself though.

How does our kit compare to the C2 kit? Well, I'm not in a position to point out what's bad in our competition's product so I'll tell you what's "right" in ours.

Our manifold is a thick walled stainless piece and will not crack.
We use 4ply Nomex couplers that will not blow out
We use T-Bolt clamps that will not let go and not cheap worm drive clamps.
We include a full 3" exhaust right off the downpipe all the way to the muffler section so all you have to add is the rear piece for a full 3" system
We use brand new Garrett products and not remanufactured turbos
Our intercooler core is a Blackstone high density unit over 3.5" thick with cast aluminum end tanks like Greddy and HKS use
We use stainless steel braided lines for the water and oil returns
We include brass vacuum tees and not plastic
We use nylon braided vacuum hose instead of cheap rubber that will crack over time
We include EVERYTHING you need right down to the oil filter, spark plugs and RTV to seal the oil pan.
We include 410CC injectors and have upgrades to 630cc
We include the timing and injector harness with the Emanage

That's the meat of it but there's more details than that. I hope that helps you make a decision.

If you would like to order a kit or have more questions, feel free to contact me via email or phone. Thank you again for considering us.

Ok so now you can see what each kit contains both are about the same amount, haas maybe like 300$ less. Which one is better for my $, secondly, has anyone heard any problems with the haas kit?,and anyone who has the haas kit please tell me more, thanks your feed back is appreciated.

Very good detailed information, Since i have no experience with Haas i really cant comment on them, however it sounds like a fairly nice kit. I still recommend the C2 kit just for the fact that C2 has impeckable customer service. There are quite a few C2 kits out there. Definatly go with the Level10 upgrade like that other yahoo with the auto did.but if your going to spend all that money, i suggest selling your celica and getting a factory turboed car and just upgrade it....for example, 90-93 Celica All-Trac. you can buy the car for under 5000. put another 4-5000 in it and have a killer sleeper.
Just like mine :)

hass kit is very new, so it'll be hard to find any feedback on it. That said, it looks like an awesome kit for the money... they really do seem to include everything you need, with the possible exception of a new fuel pump.

Hass is a very well known and respected mark in the MR2 community, so its not like they are new to our engines. I suggest you check out the spyderchat forums for more info on Hass...

To me, hass looks like a better deal and a more complete kit, but C2 has a great rep and proven customer support in the celica community... tough call

thanks for the opinion thats good idea but you already know that I want to do it to this car. I agree that as you stated c2power has impecable customer service but the question is which one is better due to the specifications I listed, and what your thoughts are as well between both of these turbo kits.

Both companies have good reputations. Both also use an eManage, which seem to work fine on GT's. The only qustion I have comes down to fitment with an auto trans. Both systems were designed around manual transmission cars.

I like the sound of Haas's manifold, downpipe and exhaust. These sound like quality, durable pieces. Haas also seems to really have the eManage figured out, and I'd trust their base maps. In my opinion, some of the cars with the base C2 systems seem to put out very little power. If it were me I'd go with the Haas, based on their reputation in the MR2 community and what they have in their kit.

That said, I have serious questions about something from both companies:

-With C2, I think their suggestion of pistons and rods is misguided. It simply isn't necessary. However, if you run the GT2860RS turbo they're including with the Stage 2 (GT28RS is the old part number, Garrett revised P/N's recently), you can crank up the boost with the pistons and rods and really get the most out of the turno.

-With Haas, I really don't like that they keep the stock fuel pump and only run 410cc injectors. That just isn't enough fuel. Given that fuel system, the GT2860RS is major overkill. In my opinion, a 1ZZ with stock internals shouldn't run anything bigger than a GT2854R. The GT2860RS is better suited the the 2ZZ engine which revs much higher. If you run a 2860 on a 1ZZ, I'd opt for the smaller 0.63 A/R turbine housing option. Their big power 2ZZ running that turbo uses a 0.82 A/R turbine housing.

thanks for the info bro once again I agree that was some major useful information. What got me looking at c2power were the upgrades for the engine, rods, pistons. Like you said as well I think the should have bigger injectors as well, but haas did offer me to opt out for the upgraded injectors. Regarding the tranny they both said there should not be a problem just send it to levelten, but I think I am going to go with jmo I heard some good things about each but jmo I have heard more about. But level ten is still a choice to beef up the tranny. Also you have been on here for a while Jesse IL do you know of anyone with the Haas setup? I know plenty with the c2power but not the Haas.

Well the 2 kits seem to be close. The question can not be answered without feedback.
We do our kits as good as it is possible in the region (Europe). It means that we do not have such a good and wide range of parts to use ( then in the US) and we also have to import things from where the kit would go back. It is not efficient for sure. However non of our competition kept for long as they did not do quality or just simply did not hold their words after sales. So I would say we maybe not the best but the most realistic or stabile. Our Mr2s kits are now being tested as the first few buyers are ordered it after they saw the results of the Spanish prototype.

Our biggest 2 problems on the gts we met:
-cracking of the manifold ( now we use thicker an beefed parts)
-The greddy tuning on the GTS as it seems not stabile. We are currently changing EM unit. We will use the Apexi PFC in our new GTS kits. The price will be 3890$ with the PFC and if wanted still 3390$ with the greddy.
BTW we have an idea to solve the problem with the greddy as well. We have to try and proove how it works.

We also had to change the GT kit as the GT28r maxed out the injectors at 6psi (not like the K4 before). So we added the 440cc injectors.
We also met cracking issues in the last 2 months so I assume we just run into a bad quality pipes that we use. NP as we are to use thicker wall pipes too on the GT.

Unless you guys have the Brashboy version of the PFC, he can't use it -- auto trans.

you know you can get any of those engine rebuild parts and many more from monkeywrench racing, right? They have more stuff for building the 1zz than anybody, by far. If you wanna go crazy high end, I'd recomend you get the engine parts from them, regardless of which turbo you end up with.

Also, you will probably need a new fuel pump with either kit, also for sale at monkeywrench (also injectors, but they come with C2 st2 and the hass kits).

Yup Thats what we do if st2, we inform and forward the US costumers to MWR. If wanted sales can be done at us on same prices(only US costumers again) as MWR.
