wudddup 1.5L twin cam turbo frankenstien mazda motor!!

No worries, brother. Part of it is I really like driven and innovative Festiva owners. Part of it is your build ideas are fairly similar to my own other than short block differences. Part of it is that you're a Western Canadian as well. Part of it is that I think this setup has the potential to revolutionize Festiva tuning.

if you want a real mans intercooler pm me... i have a big front mount that im trying to sell.... i think its 27x7 or something like that... it fits the front bumper PERFECT!!!

B8 Proteges have a 55mm or Escort GT's have a 60mm... both require port-matching the intake manifold of course.

Are these an easy bolt-on other than the required port matching?? I'm thinking like the B8 and BP TB's are a good bit different than the B3 and B6 ones.

A b8 or bp TB is a cool upgrade if its quick and painless but don't go too big. Driveability around town suffers. There is a thing as too much throttle response, especially if the spring is lazy.

I'd like to add that the automatic b8-me throttle body not only has a weird TPS but the whole TB should be passed on. Mine didnt have a shaft on the end and every other mazda one i have seen did. It's why my personal swap isn't running, I'm waiting to take another trip to get a 5 speed variant.

Right now my tiny b3 throttle body is awesome, its got some low end thats forsure probably enough to pull a trailer!!!

im defiantly going to try a different TB in the future though

thx sasquatch, i have a couple huge ones to that could fit but i like the sleeper effect of having a blacked out one that is no one can notice

it sure catches fools in wrx's off gaurd,

very interesting thread.. now lets see someone do a dohc b3

very interesting thread.. now lets see someone do a dohc b3

its possible!!!!! its 100% possible

if someone wanted to boost the power of their b3, swap a capri or b6T or miata head onto it and have a hay day!

someone please try this! i already have to many festivas/cars otherwise i would.

if that person is in edmonton/ calgary ill donate the head and intake manifold.

I got a headache trying to look how to make one without paying someone to do any machining. I got a headache, had too many browser windows open, and then saw festyfreaks thread. Don't make a dohc b3. Get a 1.5 liter like freak's going.

[festyfreak39]

infact i also have a block for that person aswell.

Actually i hold my tounge.... im 90% sure you can put a DOHC head on a 1.3 SOHC block, im 100% sure you can put a DOHC head on a 1.6 SOHC block... someone shoudl try it.

[getnpsi]

Well ii bumped my old thread asking about it. Just need some hard evidence now. We have nothing to gain but knowledge if it doesn't work and there could easily be a lot more running cars if it does work. A head, intake, and gasket kit is a lot cheaper and less cumbersome than ripping out another motor if you have a dead car. Everyone's got a b3 bottom end almost.

Ok, I see where the discrepancy and misinformation is now.

Of all B-series Mazda engines with the intake routed to the drivers-side, all of their throttle bodies interchange onto any BP or B6 manifold

Which means the throttle bodies on that list will interchange if the recipient intake has the plenum opening routed to the driver's side as well, just like the donor it came from. He should have stated late (2nd Gen) B6 instead of "any B6". It's a different story if the plenum opening is over the valve cover like the B3, early (1st Gen) B6, and B6T. The IAC on the "driver's side routed" ME style TB hangs down too far and hits either the valve cover and intake brace or the fuel rail in the case of the B6T. Also, the bolt pattern is very different on the driver's side inlet ME style TB's. 3 of the bolt holes are close but would need enlarging and 1 is way off and would require relocation to work. One last issue; there is an aluminum tab cast behind the TPS that would need to be removed because it hits the intake plenum.

I'm also wondering where he took his measurements from? I'm curious if it was in front or behind the throttle blade? A throttle body is only as big as it's smallest cross-sectional diameter and TB's are larger on the front (intake tube) side due to a bevel in the inlet which necks down as it gets closer to the throttle blade. They have to be measured at the smallest point of the orifice, which is typically behind the throttle blade (plenum side). If you measure an EGT TB behind the throttle blade (smallest point) it measures 55mm instead of the 60mm he has listed. The TB used on a B6-ME from an MX-3 is 50mm and not 55mm as stated on the CP page. I'm guessing the author measured all the TB's from the front side since all of his measurements are skewed 5mm positive.

The only TB that I know to be a direct replacement for the 45mm one used on the B3, early B6, and other "over the valve cover" intakes is the one used on the B6T which measures 50mm (behind the throttle blade at the smallest point of the opening).
