Victorian laws suck. to get the car engineered and therefore legal in vic, i had to go back to the standard turbo and manifold to pass emissions. if i'd kept the big turbo, i would have had to have a $3.5K emissions test...
But it got defected for too low, too loud, ecu, turbo, bov etc etc the handling of the car is no different. but it's a lot more fun with the smaller turbo as a daily driver, as the power of the car is delivered a lot lower in the rev range - it's not all top-end as it was. and 140kw atw is quite achievable from a relatively stock GTX engine - there's plenty of people on the boards making around that with standard GTX engines

Bumer Rupewrecht, now I know why you have the picture of the cop car in the driverside mirror! But it's interesting what you said about the car being alot more fun with the smaller turbo as a daily driver, as the power of the car is delivered a lot lower in the rev range, haven't thought about that. I am lead to believe that turbos tend to bring the power on in the mid to high rev range while supercharging in the low revs, with your situation why is there such a difference with the smaller turbo i.e. it being more responsive? how would you theoretically fix that problem with the bigger turbo scenerio? Programable ECU?

Let's play hypothetical here and everyone just have ago, let's pretend you had both 1.8L and 2.0L versions of the Mazda 323BA Astina 5dr Hatch's sitting in you garage. Your restricted to ~$10 000 and wanted to do a engine swap + further engine performance enhancements E.g bigger turbo, port & polishing maybe reconditioning depends on you, but must relate to engine performance, to ONE car only and further more you could only choose the KLZE(Jap Spec) engine for the 2.0L astina or the GTX for the 1.8L. Who of you would choose to mod the 1.8L or the 2.0L and WHY and what would you modify if you could?

I'm not sure if this is a stupid question so please bear with us, I read that the 2.5L KL-ZE engine only ever came in Automatic Transmission equipped models of the Eunos 800 (Mazda 626 & MX-6) - 1998+, Only in Japan. Also rare find but was also available on J-Spec, MX-6's with A Manual Transmission. So say if you could only find the engine from the auto transmission equiped models and wanted to put this engine into your manual transmission car would there be problems and how much would it cost you?

Astina GianT, you are a person with many Questions. I will try to answer some.
Its irrelevant as to whether the engine came out of an auto or manual equipped car as the mounting of the fly is where your box comes into play and both ATX and MTX will accomodate this. The choice of v6 or I4 comes down to what you wish to do and how far you want to take your modification process to go ($$$ dependant). If you want an NA screamer you will find the v6 is the choice (not that boosting the V is out of the Q its just a lot more mucking around and custom work $$) There are a few turbo'd mx6s and Probes in the USA as well as SC versions but a lot of them have issues with the un availability of solid HLAs and springs/ valves dropping, there is however a lot of research going on in the probetalk site to combat this problem at present. There is also a lack of aftermarket support for these engines and most of the research is done by drivers who are playing the guinea pigs with their own engines in the Quest for the bulletproof engine at the risk of costing themselves a busted engine. And with the supply vs demand stakes over there they are putting up with excessive waits on parts as the suppliers are "mostly" working out of their garage. I am not telling you that the v6 is not an opyion for modifying nor am I claiming that its to be avoided but be aware that the v6 industry is still green. I for one know that Austrack Motorsports (who deal with Chev, Ford and Holden) built a replica VX Commodore using a RWD twin turbo'd KL v6 and managed to extract 595 kw on 1.9 bar. So the figures are possible as may not be the $$$ required. Here is a list of parts published that they used: Standard block with reinforced bores Standard crankshaft (crack tested, ground and balanced) Engine bearings throughout are ACL Eagle H-beam rods (balanced) forged JE pistons and matching rings (balanced) Standard heads with extensive porting Ferra oversized valves (remaining valvetrain custom designed by Austrack) Custom grind camshafts (secret) Custom fabricated Cam Gears Twin Garret 340hp bb turbos flowing 1.9 bar (welded up wastegates Custom fabricated 316 stainless exhaust manifold with equal length 1 7/8" primaries 3'' exhaust Twin external 45mm Turbosmart wastegates with seperate dump 2x Plazaman air-air intercoolers (600mmx600mm cores)= extra pipework but less weight Custom aluminium radiator which also cools the oil Electric waterpump Custom Intake Manifold using twin 65mm Throttle Bodies (inside 6 bell-mouthed trumpets feed air to the port matched heads) Twin Turbomaster BOVs just before TB Race Grade Silicone Hoses Motec M800 ECU Ignition= original mazda multi-coil Twin Bosch 600hp Motorsport fuel pumps 6x 1400cc injectors 2x RRFPR and thats about the limit of the engine You can go ahead and guess what that one has cost to build Remember that its no longer a transverse engine And they managed to break 3 $45'000 boxes with that Well thats the world of the v6 |

It's purely the size of the turbo. The bigger it is, the longer it takes to spool up. the GTX is (roughly) the size of my fist, whereas the T03/4 was about 3 times the size, and really designed for a much larger engine (3.0L+) With the smaller size and shorter spoolup time, it means the power is delivered earlier. Big turbo takes more exhaust gasses spinning it before it starts to make power, hence why it come in later in the rev range. but having said that, length and size of piping also plays a factor in power delivery and while the GTX turbo spools quicker, it also runs out of puff at the top of the rev range. and the T03/4 wouldn't be making power until 3500->4000 rpm, but would pull very VERY strongly to 8000 rpm 1.8T vs V6NA: it'd depend what i'd bought. if i'd bought a V6, i would have gone the 2.5 KLZE NA route. presented with the choice, i'm not sure! but as a daily drive i think i'd prefer the turbo, as it's not as highly stressed all the time, as the turbo is more of an on-demand type of power. and i love the sound of turbo flutter and a blow off valve. it's the ricer in me

1400CC injectors FARK ME,
Maxda Planned a TT KL for the Mazda 6 but it never got off the ground I believe. I assume they went the four route. Far as I know no K series 6 came turbo or super charged. Any one thinkg different? Giant I have sent you a PM containng a Article re modifiing. I found it interesting |

The Austrack engine now lives in an old school Gemini wagon and they have pumped it up to the magic ton 1000hp=746kw so who knows what weird **** they've now done to that. Its too scary to think about |

Sixes
Mazda, though few people acknowledge it, also make a good selection of strong hi-performance six cylinder engines - and they're all compact size V6s. The most scorching motor of the group is the KJ-ZEM - Mazda's exclusive Miller-Cycle engine. Displacing only 2.2 litres, this DOHC engine uses a screw-type supercharger and dual air-to-air intercoolers to boost its way to making an impressive 164kW at a laid-back 5500 rpm. It's an ultra smooth engine as well, as it was designed for use in the luxurious Eunos 800 saloon. The second highest power output of Mazda's six cylinder range - at 149kW - is shared by the 3 litre DOHC JE-ZE, and the high-tuned 2.5 litre DOHC KL-ZE engine. These engines are configured to suit rear and front wheel drive respectively, however the KL-ZE is the more sports oriented engine, with its peak power achieved at 6500 rpm - 500 higher than the JE-ZE. The original JE series engine was released way back in early-mid '80s and used a conventional SOHC head and fuel injected intake system to develop up to 116kW at 5000 rpm - those fairly low peak power revs indicative of the poorer flowing head in comparison to the later DOHC versions. An engine released in various mid-sized cars such as the swoopy MX-6, the FWD J5-DE engine features a DOHC configuration on top of a 9.0:1 compression ratio, 2.5 litre block, and pushes out 211Nm at 3500 rpm with 119kW available at 6000 revs. It's not a hugely common motor, but it is very strong. Another engine produced with the intention of powering a Eunos (the 500 compact saloon), the front wheel drive KF-ZE 2 litre double over head cam powerplant is good for up to 180Nm at 5500 and 119kW at 6500 revolutions per minute. Once again, smoothness was one of this engine's fortes since it came equipped to the luxo Eunos. The littlest V6 in the Mazda line-up is that fitted to the top-line Eunos 30X sports car. Displacing only 1.8 litres and using a 9.2:1 compression ratio, the K8-ZE engine offers excellent flexibility for its capacity category. It is also good for hitting out up to 157Nm at 4500 revs, and 108kW at a frantic 7000! 'Revy' is a good way to describe these unburstable little sixes. |

Look in the owners manual for the location of the engine number, if it starts with KF then It will be a 2 litre. The heads are probably the same or very similar on the K8 and KF.

Hi,
I'm new to the Mazda engine swaps, I have just purchased an eunos 500 complete with cooked engine (2.0L) and have also purchased a 2.5 mx6 import engine from Rolin Imports of the KL variety, which should give it some get up and go. I have been asured by Rolins that it will fit straight in. If anyone can give me some info on taking the motor out eg: engine and tranny together, engine by itsself, from under the car or will it come out from the top? I have changed plenty of rear wheel drive car engines and done clutch's on front wheel drive cars but haven't done a complete engine change on one as yet, so any suggestions to make it easier would be greatly appreciated. Thanks. |
