hi peoples have just picked up my first rx7 type r efini twin turbo,now i understand the time money and efforts you guys put into the car this car is one of a kind.not sure what happend on the way back engine has been rebuilt and has coverd about 250 miles i have been told not to go over 4000rpm for the first 500miles which i have stuck too as its under 12month warranty,but was at about 3000rpm and put my foot down in fourth gear and it takes a while to get up to speed do you think this gear was to low for the revs it was at,also has an occasional misfire the car is a 1992 unmodified apart from the rear exhaust box any ideas would be greatly welcomed.

 

stock turbos should boost 10psi easily at 3000 rpm. It could be something as simple as a loose boost coupling/hose or it could be complicated to track down the problem with a solenoid or actuator.

 

check your spark plugs

 

ok cheers for the info mate will have a look tomorrow if it stops raining here in uk.

The 7 doesn't fail you. You fail the 7.

 

If you haven't completed the break in period why are you putting your foot in it in 4th gear. Get through that first before try figuring out if there's a problem. It will be a tough fight (getting them to cover the warranty)if you damage the motor before you even get through the break in.

 

At 3000 rpm, your car isn't going to have much power.

 

haha quoted for truth! thats goin in my sig

 

lol. o so true

 

You should wait for the break-in period to boss out the engine, but a better gear to make any kind of assessment of the turbo performance would be third gear. I would not expect a giant response at 3000 rpm in 4th gear.

 

I find 4th can be a bit unresponsive, try in second and these cars pop from the exhaust (misfire as you say) alot. Its actually part of the design with a factory air pump, too much fuel, and alot of heat. Adds character!

 

i know have been taking it easy got 200miles left till first engine oil change thanks for the info dude

 

thanks for the info mate,just a quicky what should my oil gadge be reading as looks very low????

 

If it reads zero or really close to zero at idle, it's probably the oil pressure sensor having a poor connection. I clean the contact on the sensor on a yearly basis. No biggie. And stay out of boost!

 

ok cheers for your help will check it out.

 

Just out of interest, who did your rebuild? I only ask as I am in the UK (Sussex) and recently had my engine rebuilt and would be interested to compare.

 

hi mate i bought the car from jimmysrx7s saturday it came with the engine already rebuilt all hoses changed with a new clutch it came with 12months warranty for £6400 their location is hoveton about 10mins past norwich they have been specialising in these cars for 8years,think their rebuilds start at £3000 but could go up if any other components need changing.hope this helps.
