Well, find out once I take it apart.

 

Sounds like the slave cylinder, but I would suggest doing both at the same time, especially if they're the OEM ones.
Bleeding them is a PITA, and you want to be sure you don't have any leftover crud that builds up in the system.

 

Well, not exactly, it was the master cylinder; and yes bleeding it is a pain... It was still the factory OEM, replacing it was swift, took about 30 minutes altogether including a flush. Before I was able to diagnose it, it would take me at least 100-150 pedal pumps after bleeding the air out until I could build pressure on the clutch, takes about three to five gear shifts until it looses pressure and not allow me to change gears. With the new master cylinder, at least 30-40 pumps and I could immediately feel the pressure build up after about 15-20 pedal pumps. Took it for a drive and I may have to adjust the push rod to get the right feel on the clutch.

 

I just bought a remaned jdm renesis crate motor... I was wondering if these hamdle a bridge port good or not? It has 10.1 compression and I have intake 70k volt coil packs yellow jacket injectors and full exhaust and seeing if these were ideal for a port job and of it is known for any major power increase let alone the motor itself.. the guy I got it from blew up his 03 and umder warranty mazda replaced it with a reman

 

I usually let mine warm up for about 3-4 minutes, then drive it around real smooth until the needle reaches the middle, give it a couple more minutes after that and you're good to go.

 

The 4 port engine responds better to a bridgeport than the 6 port .... but only because it has less intake port area to begin with . If it's a 6 port ...leave it alone , any gains are miniscule

 

Will S1 rear shocks fit an R3? A friend's R3's rear is sagging. So I guess the Bilsteins are blown. I've read that KYB Gas-A-Just is the best OEM replacement. 551116 is the part number for the rear. Will they fit an R3?

 

Hello, Im from Jakarta, Indonesia - Southeast Asia

Mazda dealers here are not good in rotary engine

I just got a 2003 rx8 se3p 6speed m/t

Stats :

70.000 kilometers ( roughly around 43.000 miles)

When i got it, the engine doesnt want to turn on (it's keep turning but not on)
and i towed it a workshop that claims that they're good in rotary.

cost me roughly 4000USD for a rebuild.

And when i got the car back, it doesnt want to start when the engine is warm.(cold starts like a champ)

The workshop says all rx8 is like that (doesnt start when hot, it's normal, wtf right?)

i know u guys prolly seen this a thousand times, i really hope there's a good answer for this.

Please help me out, im really stressed out about this car, and the Rpm idle is weird( likes to drop sometimes, doesnt have a rhythm)

Im new to this, i hope there are more rx8 users in jakarta but i cant find any( not shocked as the mazda dealers are not good in rotary)

Send help pleasee

 

They will fit, but only if you also replace the springs with S1 springs.

I find it odd that the Bilsteins would be blown. Unless I have missed it, Billies are not prone to that problem.

 

That is NOT normal. It is a sign of low compression, meaning it most likely needs a proper rebuild. Did your builder not provide any type of warranty for that price? Is there any way to get the engine compression tested?

 

Thanks for the reply Steve! They sag and hit the bump stops with 3 people inside. From the outside it looks like the car is carrying 2 tons of luggage lol.

Any cheap replacement shocks for the R3? I can't seem to find KYB Gas-A-Justs for the R3. $600 for the stock Bilsteins is a little too much for him at the moment.

 

You're probably not going to find them for an R3 specifically. As steve said, you need the S1 springs. So they're not going to be advertised as a fit for that model.


With shipping to sri lanka, and the cost of the S1 springs. It might make more sense to wait a little bit and just get the bilsteins.

 

KYBs are a significant step down in quality from Bilsteins. Best course of action for your friend, assuming the shocks really are bad, is to save for a set of Bilsteins and fix it properly when possible.

[This is an apples to socket wrenches comparison, but my Toyota Tacoma truck just turned over 320,000 miles. Many of those miles have been off-road and otherwise torturous. Its factory Bilsteins still work perfectly. At least some Billies seem to last forever.]

As I said before, I don't remember hearing of R3 Bilsteins having the same problems as the Tokikos on other 8s, but I could have missed it.

 

Thanks for the input guys! The KYBs are available here for a heavily discounted price of $80 each (since nobody buys them... since RX8s are so rare here lolol). But yeah, no point getting them if they're not gonna fit. I'll tell him to save up for the Bilsteins. Good thing I asked you guys first! He was gonna buy them today haha.

Steve, I'll try to get a picture of the rear. It's a lot lower than, say, my car. But since Gas-A-Justs are a step up from stock, and the Bilsteins are only marginally better than stock, I thought they'd both be about the same.

 

Here's a dumb question. Where did the 'Like' button go?

 

Mazda changed the rear spring perch location on the S2 cars. It supposedly improved handling, but it is infuriating. The result is that aftermarket S1 parts do not fit the rear of S2 cars, unless you swap shocks and springs together. If you are going to do that, you should everything front and rear, so it will all match up. Of course, there are no guarantees that everything will sit right.

Those same KYBs are around $80 here as well. If you believe you get what you pay for, well...

I wouldn't say they are a step up from stock. The Tokicos are actually pretty good shocks for street use until they blow.

Do you have a Bilstein warranty center or rebuilder on your island? Repairing them may be an option.

 

i forgot to mention it even has an engine leak., that workshop took a year to complete the rebuild.. ialmost gave up waiting.

Yes there's the mazda dealer who claims that they can do Compression test for 100bucks or so( quite pricey for a test in jakarta).

I saw some threads prior to hot start issues, some say ametech 400ml, some say weak starter.

I think i'll just upgrade my starter(from 2003) to n3r3 ones.

And change to koyo Aluminium radiator.

and see from there.

what do u guys think?

 

Yes Steve Dallas I noticed that also. Where did the "like" button go ????

I've read a lot of people say there's no way to decisively improve on the R3's stock suspension unless you're willing to drop $2k+ on coilovers. Given that, I'd feel safe betting that a generic KYB damper would be a significant downgrade from the stock Bilsteins.

 

Thank u brother from another mother!! I'll check it out

 

The starter and radiator upgrades are not necessary unless you know those parts have problems. I doubt they'll fix your problem, either. However, if you want to do them just to do them, go ahead. They're both good upgrades.

You should get the compression test if you can.

 

Thank u brother from another mother!! I'll check it out

 

Thanks a lot for the info! Really appreciate it. No warranty center here. Most people don't even know what Bilstein means lol. I will tell him to swap the bump stops first and see if that fixes it. Maybe it's just the bump stops.


Good point, since the KYB's are cheaper. I just thought they were better than stock because they are monotube shocks and that they are slightly stiffer than the stock Tokikos.

 

Stock coils can't be counted on to stay alive.

I put a BHR GMC Yukon coil kit on mine to make sure.

Make sure coils are new or work.

Put a timing light on spark plug wires near the plugs when warm to see if firing.

You're really brave to have such an exotic car in Jakarta. I live in 2 worlds; West Texas with an RX8, and Bandung with a Toyota Innova diesel.
