How do I get the side bearings off the LSD? (FD) Thanks!

 

ok i got a 88 tii and i just put a new clutch in it changed over the rubber line to a ss line and now i cant get the clutch pedal to build pressure back up and ive replaced everything clutch master cyl., slave cyl., new clutch kit, i even tried to put in a longer bolt in the slave cylinder and still nothing im so frustrated with this if i cant get it pretty soon im going to light the car on fire and have a bon fire with it

 

Robert do you sell a carb.,intake and exhaust manifold, turbo,all for racing application for a 20-B engine, flywheel(which year rx-7 works), what is the engines tightening torque in foot pounds(its the same as a 13-b?), is there a special way to disassemble the crankshaft cause I have been told that this engines crankshafts comes in two parts and require a special method of disassembling, and last but not least you once told me to installed a large engine breather for my 13-B at least one inch I.D. but I dont exactly know what an engine breather is, sorry for this big questionary,
THANKS

 

No one can seem to answer this, but i need to know the oil feed inlet thread on my garrett 67mm turbo. PM me asap!!

 

1/8 pipe thread usally ..

 

i dont mess with 20 b motors internally, too much money for my blood to be messing with those.. the crank is 2 pc. and i know a later model 20b (c,d,e model) is the better ones to use.. please check the 20 b section as you will find lots of usefull information there.. link to 20 b section https://www.rx7club.com/20b-forum-95/

the breather is usally incorperated into the oil filler neck . it consists of a 1" dia tube routed to a catch can ..

 

did you prime the master cy. before installing it? prolly not
here is a trick i do..

open the bleed valve, then with an air nozzle blow compressed air through the small vent hole in the top of the master cy.. use about 10 psi , ithis will push the brake fluid through the system pushing the air out of the system.. do this slowly and do not let the resivoir empty as you will put more air into the system..

 

How much for a manifold and carburetor for a 13-b turbo engine, is it true that IDA CARBURETOR OFFER more H.P. than sidedraft? if this is true quote the IDA manifold and carb.

 

in a turbo application, the ida makes waaaay less power because the float is brass, even when its modified the ida carb cannot boost nearly as high as the sidedraft carb because of the float..
the next step for you would be a race fuel injection system like the one i use on my car.. when i switched to efi, i was able to accuratly tune the fuel at higher boost levels than i could with the carburator.. i made an extra 200 rwhp with the fuel injection over the best tunup i ever had with the blowthrough carb system

 

could you please send me a picture of this catch tank installed in an RX-7

 

This is for a friend of mine, the same guy that is thinking of messing with the 20-b he bought at e-bay, I keep telling him not to use this 20-b as this engine is far more complicated to deal with, he also is working on a 13-b project so I recomended that he work with you in the process, I will tell him about the carb advice you gave me and I hope you will do business with him, I am very please with the way my car is doing right now and dont think will change my setup for a while, at least not until I get beat up by some other car........

 

Do you offer boost prepping services for sidedraft Dellortos? Also, until I get around to a turbo set up, what jets would you recommend for a 48 Dellorto on a stock ported 12A with a RB streetport exhaust system?

 

sure, i turbo prep dellortos, they work great for blowthrough applications. as far as jetting run the carb with what it has, tell me what you dont like about how it drives and we can go from there.. each car is different, so there is no set jetting
what does the dell have in it now? as far as jets and venturies?

 

i have a tech question...


where in the HELL can i buy a .81 tangential ptrim T4 housing and get it here by friday? with a vband discharge.

 

I'm not sure. It was on a 13B streetport. As soon as it arrives and I figure out how to put it on, I'll let you know.

 

ok after rats nest removal went to set timing and car died now it wont start what to do?


set at cas i went and found the timing mark lined it up reinstalled the cas properly and now it wont start it spins gets fire fuel and air but not catching help please......

 

that sounds crazy enough to work ive tried everything if this works i owe you a six pack

thanks for the advice ill get back to you and let you know if it was the problem

 

Suddenly the oil pressure on my 13-b engine decrease from 100psi at 3200rpm to 45psi at same rpms, I already check the o-ring at the front housing and replace it but still the same pressure, the engine is fresh with new rotor and main bearings , the front oil pressure regulator is 1/8 shimmed to keep up with the rear regulator which is a high performance regulator from racing beat, could it be the oil pump or any other thing that might be causing the oil pressure decreasing

 

dont worry about it.. what guage are you running? prolly off not accurate

 

That is what I thought the first time so I double check connecting an external oil pressure gauge giving me the same readings as the stock gauge on my 87 rx-7....
any advice....

 

whats max pressure at redline? id run it like it is.. dont need much oil pressure @ idle

 

Can I get the carb boost prepped now and run it without a turbo? I'm planning on doing the turbo later on down the line, after I get the rest of the car in working order... But to save myself time later, if I want to get it rebuilt and turbo prepped all at once, can it run "turbo prepped" without actually having a turbo on it?

 

Its not putting more than 45-50p.s.i at anything above 4000rpms. at idle it puts 25-30 p.s.i.

 

ohhh, not good... something is wrong.. talk to your motor builder

 

once the carb is turbo prepped you can run it with boost or n/a without any issues
