HI Boost Turbo for MP5

[pro5]

Can anyone who has installed this turbo or one like it please let me know the pros and cons of installing it over stock engine?

I like the idea of more power but I don't want to sacrifice my warranty as my car is almost brand new (11,000 kms). Is there any other modifications that can be made ie.headers etc?

Thanks....
love my MP5

long story short, if you like your warranty - don't mess with your car.

this has been covered and debated many times.

Pro5 pm pirana he has installed the hi-boost turbo kit on his P5. If you don't want to **** up your warranty I would suggest getting an intake and cat-back exhaust. Mods that are bolt-ons so that you can switch things back to stock, nothing permanent. Either that or don't mod at all.

do a quick search in the FI section.

I have mine......and I love it. I am in the midst of putting together a personal webpage that shows the install....and dynos...and videos.

also...check with Deckoutp5 and Pirana they are the other 2 active members that have this kit.

I personally believe that the hiboost kit is the best...best value for the dollar.... outstanding engineering in the parts..... and ECU based Fuel Control.

You will hear different views....just do your research.

Proper A/F management is the key to engine life and reliability.

Turbo + warranty = no warranty

Here's the dark side of what can go wrong

I've had the privelege of riding in Rishie HiBoosted P5 and I must say, WOW. The quality of their kit is probaby among the nicest out there. Not to forget that it comes with the engine management.

 

[Pirana]

HiBoost all the way...you will have no problems on the engine. Will need a new clutch though (thumb). Check my link for pics of the install.

 

[pro5]

Pirana and YP5,
Why would you need a new clutch? and being here in Canada I am worried about the temperatures we get (eg.-30C). I want to be able to still have the car as a everyday driver. YP5, does your car still run the same at these colder temperatures?

Thanks for the info. By the way were both of your install's done yourself?

 

[YP5 Toronto]

The stock clutch will not hold the power...over a short period of time the stock clutch will become worse due to increased ware. I have the clutchmaster stage IIR and the dealership that installed it noted that it felt like stock..... from a performance position...it grabs on quite nicely. At 200lbs of torque...the stock clutch is not going to like it.

The only concern that is being worked out with hiboost...is starting the car up in cold weather. This will be worked out more as I tweak my maps to adjust for the cold morning starts.

The car is awesome in the cold.....it is a bit more responsive, but the key here is that the Haltech is dynamically adjusting. It is taking into consideration Air Intake and Coolant Temperature in adjusting the A/F ratio.

Colder Air = Denser Air = requires more fuel (please tell me I got that right)

not enough fuel in cold air conditions will increase your risk to detonation.

Not to bash anyone , but if you do a search of blown motors that were turbo, you might want to reconsider your choice.
sorry to anyone that might get offended.
5,000 miles of boost on mine

 

[YP5 Toronto]

terry...had his MP3 running 8psi on a T3...for a year+...

if you do look at the blown motors...they all admit to (most of them) to running higher PSI than perscribed by the kit manufacturers.

proper use of the various kits..... is the key....

remember the MSP block is the same as the P5...same rods...same pistons...

the key difference...is that they have proper a/f ratios....

One thing...you did need to understand more than just the fundamentals of how a turbo system works.

 

[pro5]

YP5,
Can I trust Hi-Boost recommendations for A/F ratios? I do admit that I don't know much about the topic so I will need to research the subject. If the block of the MP5 and MSP are the same, etc, why didn't Mazda go for the extra horsepower that this system provides? You'd think Garrett Turbo's could provide the same power as Hi-Boost........

 

[YP5 Toronto]

I will be posting (very soon) my dyno runs a few weeks back. They show a rich A/F ratio...to be on the safe side.

This being said there is plenty of room to tune it down. As with any kit...regardless of manufacurer.... A/F monitoring tools such as a wideband or the Greddy A/F Guage should be used. The key to this system is that as you change items on your car (exhaust, piping, injectors) you have the ability to retune the A/F ratios to take into consideration this very important changes.

Mazda has to be conservative...they need to support a "model" that best takes care of the factory warranty and its overall effect on the BOTTOM line and also...the long term marketing persective. The list of reasons can go on from a marketing position.....

The garret t25 is much much smaller the the IHI VH-22 (i hope i quoted the right model #) that is used in the Hiboost kit. This IHI turbo is larger than the largest T3 turbo from garret (this does not include a T3/T4 combo...before the reponses come out).

Moreover, the IHI is a ball bearing turbo...which aids in spool up (some please clarify if the MSP T25 is ball bearing....my memory is failing.. lol)

 

[turboge]

Yes colder air = need more fuel.
Yes T25 on MSP is ball bearing.

MSP is overly rich stock, Hi-boost kit is pretty rich as well.

 

[pro5]

YP5,
So if I purchase the Hi-Boost kit (do you buy it directly or do you know of a Canadian supplier?) I will be able to run rich and thus not kill my engine?

What would I need to complete the install (ie. You have mentioned a new clutch and a boost gage)? What else is needed?

What kind of highway rpm's does your car run at? Was there a increase in noise and is there a considerable amount of turbo lag if any?

Thx. Muchly appreciated!

 

[YP5 Toronto]

There isn't a Canadian supplier that I know of.... but Hiboost ships to Canada at no extra charge (Juan jump I if I just gave away some of your money).

I purchased mine directly from Hiboost....and installed it myself. The only thing I needed to outsource was tapping a particular part of the radiator system (for the coolant temp sensor)....machine shop charged me $5. Other than that.....there is no need to have anything welded....or fabricated...as it mates up perfectly with the existing components of the car.

It runs rich....but truly...you want it to run at a better a/f ratio for better gas consumption.

Clutch is recommended..... boost gage a must..... that should be all....as a must....either A/F gauge...or EGR gauge is also strongly recommended...its your alert to things if something goes wrong...

RPMs are not a consideration.....the cars like stock outside of boost.....boost is not directly related to RPMs...its related to exhaust gas speed (basically when you are really on the throttle).

With any turbo....your exhaust system is quieter.

as for lag...I am at full 8psi at around 3000 rpm.... this system does not have any lag.....smooth HP/torque curve.... it pulls and pulls...

 

[pro5]

YP5.
What can I expect the total cost to be then (Clutch, gauges, turbo itself) roughly?

Have you had any problems with your local Mazda dealer in terms of servicing?

 

[YP5 Toronto]

I am out of warranty......besides.......nothing on my car is stock anymore......right down to my suspension.... the dealership I go to...absolutely loves my car. Turbcharging the car will void any engine related and maybe transmission related claims.

the kit is $3995 USD..... you can try to make arrangements with hiboost on trying to reduce the duty on the product (lower the reciept price).

Boost gauge.....as cheap as $50 cdn

Clutch...visit www.rr-racing.com

I basically started a spreadsheet 1 year before buying.....planned out almost every detail so that I could properly prepare the funds needed.
