What's the most boost a DOHC B6T can take....?
Hi
I have an mx-3 with a B6T DOHC
and i'm planing on rebuilding the engine and put those parts in
-forged cylinder heads
-new valves
-new cam shafts & cams from miata
-new springs
I was wondering about how much boost could
i run through the engine after using a turbo with
out damaging the engine????

See my post about the small B6 rods in this forum...I found the breaking point of the B6T's with small rods. The 88-89 GTX B6T engines have larger rods and the GTR BPT engines have even larger rods yet! Anything over 500HP I'd HIGHLY recommend forged pistons and rods if you want longgevity!

I have seen B6-Ts run over 18PSI which is like 1.2BAR (lol getting used to the UK things on 323gtx.co.uk)

well seeing as though N/A BP rods can run up to 25 psi, braking point seems to be about 28psi.
GTR rods are the strongest of them all
the B6t rods will shatter they are made differently than the GTR's so the GTR's are stronger.
but B6T and BPT rods will both hold up to 30psi on a PROPERLY TUNED ENGINE.

Boost pressure isn't what breaks them if the car is tuned correctly. HP & Torque is what breaks them. 300-350WHP is the max I'd push the small B6 (same as NA BP) rods if you want longevity. Mine took 24-26psi daily with a couple times at 30psi for over 10,000 mile and I was making around 400WHP @ 24-26psi. I snapped the top of the rod just below the wrist pin like a tooth pick!

I also push then to 28-30 and 400 mark. But Again tuning and what you have on the car to tune with is the key. Its possible to kill the engine at little or no boost if its done wrong also. so help you self and do it right.

ok so the
BPT cam shafts are the strongest ones?
If i put some after market valve springs and valves would that help the
longivity...
i was wondering can the cylinders get damaged if i put to much power in the b6? what if i put some forged cylinder heads??? then if only the cams and the valves break after so much milage then all i have to do is rebuild the motor every so many miles and change the cams and stuff???
to tune an engine what do i need, adjustable cam gears, a blow off valve on the turbo, programable ECUs??/ what else????
I don't think i'm gona run much more than 300 HP but once in a while at the track i will probrably try more boost and get more hp
thanx a lot, this is a lot of help

This isn't a bash so please don't take this the wrong way. After reading your reply you just posted I'd HIGHLY sugguest you go to a bookstore and get a book on "balancing, blue printing, and rebuilding engines" before you even begin to start buying parts, let alone tearing into the motor. Take your time and read up. Please don't just jump into building the motor after what you just said...your going to cost your self a LOT of money and frustration! After reading up on engine building and then into at least these topics on http://www.howstuffworks.com we can then further assist you or you may want to have a well know Tuner Shop or engine builder do this for you.
Suggested things for you to look into:
-How Engine Management
-Electronics and how to read schematics
-How an engine works
-How turbos work
