Best Bang for the Buck Motor Swap?

[micah]

looking to make some pretty serious power. the B6T seems nice b/c of the availability of parts and the fact that it has an iron block and already built for a turbo. however, the BP's seem readily available and seem capable to handle a fair amount of boost as well. lastly, would be the JDM BPT (which is what i would prefer) but i cant find one. anyone know where to get one?

what do you guys think i should get/buy? any and all opinions are welcome...

thanks in advance!

Depending on the power level you want to acheive I'd say the BP is the best bang for the buck. Practically a bolt in with some simple wiring.

[micah]

well, i definitely want to go turbo and wiring doesnt scare me. does it make more sense to just get the B6T or will a home made BP+T make more power? i want something fairly reliable (wont blow up easily) and would like to make around 200 hp (give or take). the more the better but i understand that there are limitations without actually building the motor (which i would rather not do until i have to)....

i would go b6t. that way the wiring is out of the way for BP+T later on. ill go out on a limb and say you probably can even use the b6t ecu if you get a piggyback and dynotune after you find a BP+T. no one said you have to keep everything oem on the b6t either. you can probably pick up another 30-40 safe horses with a larger turbo, water injection, intercooler etc. the advantage of b6t over run of the mill escort engine is its designed for boost from the factory.

if you cant get the jdm engine youll have to rebuild a 1.8 yourself using lower compression pistons and turbo valves.

I would go BP+T for ease of installation and wiring and you can get running right away and then collect the parts for your turbo system. If you are looking for only 200 HP, you won't need to change any internals on the BP.

There have been several members here that have made an easy 200+ HP with a B6T. The B6T will fit easier then a BPT. Both ProjectB6T and Turbostive made around 230 WHp with B6T motors.

[micah]

id be more than happy w/ 230 whp. its also about whats going to be cheaper to get vs build in the case of the BP-T (in general) and easier to fix/source parts for down the road should something happen. for instance, one thing that concerns me is if i have a tranny go. the B6T trannys are pretty hard to find it seems (correct me if im wrong).

also, which is easier to get installed as far as mounts goes? seems both need a few custom mounts if you want to run their respective transmissions but im going to assume the BP-T would need a bit more work since it was not designed with a similar platform in mind (i.e. even the axles fit width wise w/ the B6T).

The G25MR tranny will work with both the BPT and B6T. And the motor can be sourced from any Capri XR2. If you buy a XR2 you will have everything needed for the swap, engine, tranny, axles, and wiring. The XR2 and Mazda 323 GT are the axles you'll need. Both cars have the G25MR trans and B6T in them.

the b6t was making almost 200 hp stock was it not? i remember hearing that it was easy to get 200+ hp out of a b6t. i think i'd go b6t, cause everythings already there. just my .02

[micah]

yeah, ive done my research on where to get the motors and what seems to be needed. thank you for making sure though.

mainly just debating if it makes more sense to get the BP and turbo it or just get the B6T...based on what you guys are saying, it sounds like the B6T might be the way to go to begin. theyre just a bit harder to find than the BP it seems...

im still open to any other opinions etc.

unfortunately the US B6T didnt make that much power stock. the JDM ones made about 147 hp stock...US was around 132 hp i think. here is a good place for info on the Mazda family of B motors....

Entirely different wiring harnesses, sorry

the advantage of b6t over run of the mill escort engine is its designed for boost from the factory.

Thats a run of the mill BP. its turbo'd in other markets even the God of bp's the GTR's BPD is the same block & such. The BP is designed for turbocharged duty, even in NA versions. With the factory forged crank, rods, and pistons, oil squiters, bearing girdle, iron block, and many other features that just beg for alot of boost.

if you cant get the jdm engine youll have to rebuild a 1.8 yourself using lower compression pistons and turbo valves.

yeah cause 8.2:1 stock bpt vs what 9.0:1 in the protege is such a huge difference

136hp=b6t
176hp=bpt
:p

[geezerstiva]

ok so i was wrong. your just gettin me back for the 19993 thing arent you? :lol:

[micah]

and while we are on the subject of actual BPT's...are the JDM ones even available/for sale through any importers? i know they made very few of the Mazda Familia GTR's in 1992 (again, thanks to wikipedia for the info) so im sure they are next to impossible to find. sounds like the closest you will get is building your own w/ a BP motor from the US...

sounds like i should just buy a US spec one and turbo it.

and awesome info muscle_Car1...thanks!

lastly, what should i expect to pay for a complete B6T or BP swap? its easy to see what whole cars should be going for but i dont know the market for just swaps and dont want to get ripped off.

ive ordered my teins today so am excited to get going on making my festy faster!

^^You can often find JDM BPT's on Ebay and through other importers. The prices vary, shop around.

Wanna BPT?
