hello everone, just got my 1st rx7 and am very new to rotarys, the car i bought had recently had full rebuild with large streetport, there are a couple of questions, first of all what is a large streetport and also when changing into 2nd and 3rd gears theres alot of stuttering at low revs(very annoying)it has exeedy six puck clutch which is very challenging, also i live in the northeast, could someone tell me the nearest rotary specialist, cheers all nick.

If the 6 puck is annoying you, get rid and get something a little less brutal unless your gonna be going for major numbers. The streetport is the increasing the size of intake/exhaust ports and large ports are usually used on big singles as the bigger ports allow the big turbo to spool quickly. On standard twins the larger ports will make the engine pull harder higher up the rev range i expect.
 
Dont know what the stuttering could be does it feel like the drivetrain or is it the engine struggling in the low revs.
 
The closest rotary tuners to us are either, WGT just south-west of manchester (I use these and Pip has a great reputation) or Lindop in north wales.
 
Pretty sure Jurgen at J-M Imports is now doing rebuild\'s but not sure what he does with regards to faults/servicing etc but worth giving him a bell too as he is only in north sheilds.

Hi there, don\'t panic, my car shudders at lower revs, mainly when in gear cruising down in speed, just dip the clutch :)

If this is your daily drive car then changing to an uprated organic might be a good idea, that 6 puck clutch has been put in there as a large streetport will be making good bhp figures if set up right.

One good tip I should let you know about with rotaries goes like this:

When its cold, drive it like its broken, when its warm drive it likes its stolen.

This means that you should never thrash a rotary when its cold (either with revs or boost), needs to get up to temperature for all the seals to expand (else the engine won\'t last long).

When its up to temperature red line it at least once each trip so that there isn\'t carbon buildup on the rotors :)

Keep an eye on temperature and boost levels, and if they have put one in, the wideband O2 sensor for air/fuel mix.

Please please please only use high octane fuel like tesco 99 or V power, the cheap petrol could cause detonation on boost causing the loss of the engine, not good! Its a performance car and needs performance fuel :)

If you are unsure of anything just post up on here, some problems are common and can easily be fixed :)

thanks mitch, was wondering if i could use tesco 99 ron cos the price of v-power is just plain stupid, also the car had following done,
  • New rebuild with large street port
  • Non-sequential twin turbo conversion
  • Apexi Power FC ECU + Commander
  • HKS twin induction kit and cold air feed
  • Greddy Elbow
  • Oil Catch Tank
  • HKS Twin power ignition system - new with rebuild
  • Aeromotive fuel pressure regulator - new with rebuild
  • Uprated fuel rail and 1600cc Bosch Secondary injectors - new with rebuild
  • Ported Primary injectors
  • Lightened and balanced fly wheel
  • Single plate 6 Puck Greddy clutch - new with rebuild
  • Re-amenya strut brace
  • HKS front pipe - new with rebuild
  • Full Tiger exhaust system - new with rebuild, should i think about uprating the intercooler and radiator, was told she was running about 350bhp whether that flywheel or wheels im not sure, also log book says 1 previous owner, would that be in this country or all together, cheers nick.

Your sir have bought a nicely (and safely) modded FD there, although it should have uprated side mounted intercoolers, but check around for options such as a V mount on the forum, an intercooler upgrade is important on higher boosted cars. I would DEFINATLY get an uprated radiatior, rotaries run much hotter than piston engined cars, and if the engine overheats - even if its a bit - you will probably lose the engine, so prevention is better than a cure, make sure you get a good make like Koyo for the radiator and maybe some uprated silicone hoses :)

When you do get around to changing tyres, spend the money on them, its the only thing that keeps you on the road! :)

neil i think its the engine struggling at low revs, only seems to happen in 2nd and 3rd but it might be me driving like miss daisy aswell lol, glad i took the plunge tho, what a car, got up to 150mph the other day in the same time it took my teg type r to get to 100, christ that power is heaven sent, good job its just my weekend whip tho it eats petrol like nothing else, cheers nick.

If its the engine mate then i would deffo book the car in for a specialist to check the map over, last thing you want is your fresh rebuild going up in smoke so its £200-300 well spent imo.
Also when a rebuild has been run in its common practise to get the map tweaked to suit.
 
I too came from a itr straight into the rotary and the straightline speed is just taking it up another level. Still wanting another itr for the daily hack though.

yeh im from whitby, was going to hang around for you but my mate had to get back. looks like you have got your self a very nice rex there bud.

get some pictures up of the engine bay as well :D  so do you know who mapped the ecu?? as neil says, get it checked out and tweaked if needs be.


i some times get the chugging as well, check/tighten up your throttle cable, should help out alot.
