anyone knew fuel consumption for SR20 & 1JZ per liter??

btw this is SR20 in a RX8...

Time to install dual oil cooler like OE Mazdaspeed
Mazdaspeed one so sweet,even got duct that bolt up to Mazdaspeed bumper
@TS,going from point A to point B is why your engine kong
Need to rev the heck out of rotary to ensure reliability after the engine warm up of course
Another trick can use is pour some 2 stroke oil into fuel tank when filling petrol;Will help your engine reliability,especially rotary and make it perform better while at it too

I found a shop in Klang call Naga Motorsport already start install SR20 into RX8

https://www.facebook.com/media/set/?set=a.4...88552926&type=3

I heard some bad stories with Naga...

there is no update on the progress....

what kind of bad stories bro??


yesterday adi go to LSF, i have to wait into the waiting list, earliest on JULY...
only LSF can make the speedometer work properly, other workshop dont have the expertise to do such..

is it worth it to wait?

I wish I can find the story. But is in facebook.

y the heck do u wanna bother with using back the rx8 speedo? if u want to convert to SR or JZ engine, just use back the meter from the halfcut (if it can fit into the dash. i think S14 & S15 meter can fit). personally i won't be bothered with the wiring compatibility, if the meter can't fit into it, then use Apexi RSM and a fuel gauge to look at the fuel level. if u convert to other brand engine, must use back that halfcut's wiring, don't lek lek go and do hybrid wiring because that'll be idiotic, and it'll make your head bald.

personally, i'll go for the SR20det and make it around 280whp for street use. the Renesis engine is just too darn underpowered / under torque for everyday use, and too darn thirsty. not to mention the maintenance of the thing. and using SR won't hurt the balance of the car too badly. it's a lot more heavier than the rotary but at least u don't have to worry too much every day about maintenance, fuel and what road to rev the car to the max just to clear that carbon build up in the rotary.

1jz is just too heavy for that car, the balance of the entire car will be severly ruined, and every time u step on the gas a little bit, your tail will slide. i know, because i'm driving an E30 with 1jz vvti, and i don't have LSD, if have LSD like the RX8 u will be praying for survival every time it rains. and u have to use auto GB because the rear diff of your RX is not going to last even 1 week with a manual 1jz. use 1JZ only if u plan to drift the car.

if for weekend use of course use back rotary.

there are a few sports cars that are worth to buy starting this year, 1 is the fairlady 350z (which can easily be converted to RB26dett) and the other is the RX8 (which can plonk in the SR20det). both are very cheap to buy, both have big disadvantages using their original engines but will be awesome if u do an engine conversion.

the fairlady is it's stupidly high road tax but very low hp per CC. change to RB26dett although is a very expensive process, but every year u don't need to pay 4k for road tax, only pay 1k plus for 2.6. and u get tonnes of hp and tonnes of g-forces to play with. or u can just be a cheapo and convert to a 1jz vvti and save at least 5k on the conversion.

the RX is it's troublesome maintenance as an every day car. change to SR has a lot of benefits and only 2 downsides. it's easy to maintain, easy to feed, easy to drive every day. downsides are only u don't have the pure bred rotary goodness and that revving sound, and the balance of the car is kinda ruined (which i don't really care since drifting is more fun than pin-point precision driving)

Bro, u know a place that can mod external fuel gauge? my fuel gauge kong, and a few workshop doesnt know how to repair or cannot find whats wrong :facepalm:

bmw workshop says the wiring has been modified, so he scared want to do it. Another workshop says he cannot find whats wrong. Recommend me to strip the car and redo the wiring altogether (since my car wiring very )

using 1jz in e36

sorry, can't help u with that

its nothing wrong if i can used the ori speedo gauge...
since it is around the same price with other workshop that cant do it...
LSF can do some wiring modd to make it functional... but need to wait..

agreed with u bro... i may go for SR20 turbo... 1JZ seems to be very heavy...

the point of not using the ori speedo is to simplify the wiring system with the new engine. using back the meter from the halfcut is a plug and play process, no need to mod this mod that, and it makes future maintenance a whole lot easier.

Seem like the world worst trust engine.

Where got faulty issue on more or less clocks at 100k Kms mileage only..

Lol.

I agree but to disagree at some points. A brand new engine of any type can be damned too easily if the driver doesn't give a heck in caring nor servicing it. U don't need 100k of mileage to trash a brand new engine, just by 'violent driving' coupled with disregard servicing and the rising of engine temperature can kill a brand new engine in no time, needless to mention a fragile engine such as a rotary lol.

I suggest you overhaul the rotary engine at SC, safer and less likely you'll get conned. Rotary engine lifespan is 7 years, at least guaranteed could serve you well for another 7 years. If you sent to outside workshop, they'll charge you highly markup cut throat price for the parts and you don't know whether they really buy the parts or just re-fit the old part back to con you.

Price of overhauling Japanese engine at SC for totally blown engine:
- Inline4 engine around RM4k+ and never close to RM5k
- V6 engine range from RM5k-6k

Conman Ah Beng workshop could charge you RM6k for inline4 and RM8k-10k for V6. Also, many Ah Chong Ah Beng workshop are run by unqualified self claim foreman that don't even know what is Automotive Engineering course. Not even the minimum MLVK no CNG certificate with on job training.

Recond engine is nothing more than dead engine that they just fix to level where it can move but will give you headache shortly. Those old engines could be taken from cars that got total loss in Japan and given to you. Also, they don't even know how to calculate pressure, the air intake and exhaust manifold to muffler are nothing more than just sendiri tarik style that end up choking your engine. Either not enough pressure into engine or too much pressure into engine but exhaust pressure too low to pump out the exhaust causing carbon buildup and engine suffocate to die early.

Mind you, carmakers don't make straight air intake and exhaust with reason, curvy bengkang-bengkok tubes are there to generate enough pressure before pumping into engine and also creating pressure for exhaust gas to be pumped out of engine out through muffler pipe.

Don't pandai2 go change engine. That old SR20 engine or RB20 is too heavy for your RX8, you might understeer easily. Also fuel guzzling like mad. If you wanted to change engine, better you buy brand new Altis dual VVTi 1.8L or Korean Nu 1.8L or Theta 2.0L engine that save FC yet lightweight around 120kg or less.

Exhaust too, don't bother to change, more likely to cause pressure loss and the car can't digest exhaust properly.

Errr
FYI,Ah Choy is one of the best rotary specialist around i suppose
Most of malaysia rotary is maintained at there one

Frankly,i would be more worried if i drive RX8 and send it to service center
Ah Choy also got goodies up for sales one
R3 Recaro interior,19" wheel etc

Been into the same situation,too...(Massive CNY Traffic Jam when going to Kedah in early 2012)

No such problem happened....So that was my luck,also.

But to add one more thing,carbonized rotary are not good.So whenever I got a chance I would rev tha b1tch hard enough especially when I was driving more than 1 hour without any redlining...I would find my way to doing it.Luckily it also handle better in corner than my fat Z33 so it kinda easy to push the engine while having a road-worthy fun with that.

So far no problem with my RX8 but mine was revised & facelifted version so you can expect that Mazda has made some revision on the engine,ECU & such other than just a look.(first gen ECU reportedly had a problem especially on the AT version where the engine management system didnt pumped enough engine oil during high-speed engine operation but it happened on several chassis no. if my mind served me right...In US the problem has been led for some class action suit & Mazda does make sure all the infected' model no. are getting free software update...)

Changing engine is good for reliability & power but not sure how it would effect the chassis rigidty & handling.So far I love RX8 because of the handling,& sharp steering respond.Been into track for quite a time with my Z33 & Nissan sportscar always felt heavy & less steering feedback.

I can say the RX8 had the same steering feel & handling behaviour as the NSX....Only a lil' bit sharper',probably that just me,but smoothness of wankel engine(where the polar of momentum are not up & down,but rather spinning directly on one linear direction) are making me just a bit more confident on driving it to the edge rather than both NSX & Z33.(Which I also happened to own,as well)



Ah choy is a good wankel mechanic,go for him.Best rotard guy ever !

Regarding the RX8,I admit I was love the facelifted model in Nemesis Blue & R3 package...Look dammmn good!

the older also had issues with the stock battery and the starter ... for the pree 2005 batches if i remember .

1jz would probably be awesome...
but not sure if that massive 6 pot engine would affect the handling of the car....
hmmm
