SE UPGRADE KIT

[Russellb]

They are a bolt on mod (Simply well that depends on how good you are with a spanner )
There are no ECU mod needed but there is a long delay when transitioning into boost.
Have fitted one before and it improves the top end

There are no ECU mod needed but there is a long delay when transitioning into boost.

Thats what the 02 clamp is for, it addresses that lean hesitation as a result of the ECU seeing stoich during that transition. If your running a piggyback that simply adds a pulse width to the ECU's demands then it will be overidden by the OEM ecu and you will still be left with lean hesitation.

LOOKING AT THE SP MOTORSPORT KIT ARE THEY WORTH THE MONEY AND ARE THEY SIMPLY A BOLT ON AND FORGET KIT IE NO ECU MODS ETC

No need for caps talby we can hear you, there are cheaper alternatives then SP motorsport kit to get power out of SE. Search function is your friend

[Boyracer]

The SP motorsport kit includes a very expensive cold air intake that is not really needed...you can do similar mods for a lot less money.

Such as, any suggestions would be appreciated

MX5 Mania do a basic upgrade kit too, well priced from memory and proven results.

$1200 for an intercooler and air intake

The SE's restriction primarily lies in the breathing department.

You can purchase bolt on CAI for the mazdaspeed (SE) such as AEM intake (ebay) or flyin miata intake (www.flyinmiata.com).

Any decent exhaust shop can fabricate a custom stainless down pipe with HFC and muffler, there's not much gain in changing the mide pipe unless your chasing every single kw. Flyin miata has a sale at the moment on mazdaspeed exhaust systems.

You can pick up an IC off ebay, something like this

If you do the math all these bits will come up alot cheaper then both Mania/SMB kits which should give you 130-135rwkw in shootout.

I was talking to David at Mania the other day and they have ditched the Ebay intercooler on their race car for a PWR one. He was amazed at how much the cheapy intercooler restricted airflow to the radiator compared to the PWR one. I guess the old adage of you get what you pay for applies to intercoolers too.

Did the mania car change its IC since the last oran park meet? At the oran park meet the mania car appeared to still be using the the SMB IC. Ironically that IC is larger and hence covers a greater surface area of the radiator then the ebay one.

When I ditched OEM IC for the ebay one, I measured 6 degree drop in pre and post IC temps and had no boost drop on the dyno which one might expect from a larger IC.

Have had no issue with heat, but then again if you flog your car constantly under track conditions you would expect a heating issue..............

I think they swapped it before the Oran Park meeting. David was commenting on a marked decrease in engine temperature after the swap. But you are right blackster, it is a huge intercooler and covers much more of the radiator than the ones you SE guys are using. I just thought it was interesting that a different brand of intercooler would change the amount of air passing through it.

Plus they cut two holes in the front bumper.....for extra airflow.

Yeah track must cause a butload more heat, working the car a lot harder tha most would on the street.

It seems from the comments on here they may have been using too big of an intercooler (or perhaps insufficient ducting). A few people have used the mania cooler kit and seem happy, and can prove results, for $600 I reackon it's good value.

[blackster]

The ebay IC that can be used on the SE comes in two sizes.

550 x 140 x 65mm leaves a proportion of the radiator exposed.

550 x 180 x 65mm which covers appears to cover entire surface of the air dam like the PWR/SMB. This IC requires manipulation of air con pipping in order to fit flush , that is if you choose to use the OEM IC pipes.

Flyin miata do have a IC as do BEGi for the (mazdaspeed) SE, if you want something a little more flashy. But again it is roughly the same size as 550 x 180 x 65mm.

The heating issue on tracked turbo MX5s is pretty universal, (whether SE or SP), I guess thats why the serious guys appear to do the coolant bypass mod in an attempt to address it.

Huh? What cooling isues with SPs on the track?

I am surprised with how cool mine stays on the track even with the $2 mod (and therefore a boost increase) in place. I even went and installed a real water temp gauge because I didnt believe the factory "dead spot" version, but even the linear gauge shows a fairly constant temp.

More serious units like Mania's I can understand though, they are running considerably more boost than us.

If there wasnt an issue with heat under tracked conditions, why bother with the coolant re-route mod, aftermarket radiator or an oil cooler?

We are talking about modified turbo 5s that see nothing but track conditions, mania's car was brought by garry as they alledge they had a cooling issue. Be as it may that they a running large amounts of boost, there are another two tracked SPs off hand that are not as aggressive as mania's that run identical cooling mods.

Yet to see a SE/SP on a club day complain about heat issues after few fun laps at the track, although add modified and pounding race conditions; the OEM cooling system appears not efficient enough to cope.
