help on my new fc

sim · April 17, 2006, 01:55:37 AM

not long brought a red fc turboll on a (h) it has 110,000 miles on the clock but has service from new to 94,000 and engine sounds sweet but then im new to rotary so dont know wot sounds good or bad but is quiet when running and has a smooth power delievery do you think it will be fine. Plus had it up on a friends ramp which i am lucky to be able to use has and when we have time and found that someone has fu*ked the exhaust up, Well the pipe that comes of the turbo and the cat are both about 3" in diamater then goes from that to a really small peice of pipe about 1.5"/2" (which looks like the same di as the standard pipe that came of my 1.6 corsa) then comes to the splits to the rear cans. I will be taking it out but do you think it will hinder performance with the silly little pipe in place. think im goin for 3" all the way. whould really like a view on the matter

You may find this was done for a reason, When Rotarys have high flowing exhausts they tend to be Loud!!

I think who ever had the car before you may have found this out First hand, they have proberly put the smaller bore pipe on to quieten it down to sell it.

If you are going to fit a big bore Exhaust, My opinion would be keep it 2.5" unless you are looking for serious Power and fit a center box, this will keep it usable and it won\'t attract lots of unwanted Attention if you know what i mean.

i was told this but as the car has standard pipes on it and they dont even look like they have been of for a few years just had my doubts but thank mate

and by the way wot do you think about the engine shall i get it pressure tested anyway

I had a think about this this morning, Does the Down pipe have a Cat on? What you may have is a decat down pipe on a std Sytem?

If its a UK car there should be 2 cats, one large on on the Down pipe with lots of tin around and the second as part of the Mid pipe. Its very Commem for this to be replaced with a DeCat pipe.

When you say Presure test? do you mean the engine Compresion test? If so this is always nice to know but it can only be done properly by a Rx7 garage (i think your closest one is Pip at WGT //www.wgtautodevelopments.co.uk)

Grizzly · April 17, 2006, 06:59:36 PM

lets put it this way i only had a problem with my MOT\'s once and thats when i had it running REALY!!! rich (to the degree i think there was liquid fuel coming out the tail

then they only failed it becouse of excesive Visable smoke :evillaugh

that is cool then i can go ahead and book it in for a system then now i know the car sounds good, it has had some work on the sills but not many cars that old that ent, oh one more question when i use the foot brake i get a shudering though the steering wheel now i think this could be a few things 1 warped discs, 2 bushes, 3 sticking callipers, checked the bushes, now there ok and the owner b4 me had new discs and pads but they still could be warped wot do you think and has anyone had this before

Grizzly · April 18, 2006, 01:06:59 PM

before you go changing stuff check the Bottom ball joints are good (i had a simalar thing with mine)

Does it do it more when you push the brakes harder or is it more ovious when there just on?

sim · April 18, 2006, 04:23:33 PM

the faster the speed and the harder you break the worst it gets other then that its fine

Grizzly · April 18, 2006, 06:04:53 PM

Yeh Ok check your Wheel bearings and Disks. More likely to be Disks TBH.

sim · April 19, 2006, 06:21:58 PM

im going to chance wheel bearings anyway so will do the lot i think thanks for all your help mate

The calipers will free up nicely with a bit of time and some wd40

Watch the rear calipers, they are a bitch and notorious for finally going beyond the point of repair. (Hand brake section)

I had this one my TII - turns out it was a warped rotor on the drivers side. And the these were pucker mazda discs as well - never again.

Running Black Diamond drilled and grooved now with hawks - much better breaking ....
