so i have the escort gt 92 now, i sold my LX after i realized i should have gotten a gt :roll: so how is the mazda 1.8 bpt swap, im going to be swapping it over myself, so if anyone can give me info on what parts im going to need it will be great thanks

 

[escort_waat_69]

O YA btw, whats transmission should be used! thanx again

 

[Beaverboy]

You're pretty much going to need an entire GT. Everything under the hood is different.

 

[escort_waat_69]

i already have the gt

 

[Jeffescortlx]

So you sold your LX and got a GT, so then what exsactly are you swapping what into? Why not just drive the GT?

 

[escort_waat_69]

i want the turbo engine

 

[escort_waat_69]

swapped into the 92,

He wants to put in the BPT engine.....

do you know where you'll buy the engine from? cauz most of the shops sell this engine with an AWD transmission...so... unless you make the AWD into a FWD....you will have to use another transmission...

I think you can use the stock BP tranny but im not sure...

 

[escort_waat_69]

so thats the trans that comes with the EGT

I just wonder why everybody take a GTX and modify it...
The 1.8 GT engine is the same (more or less) than the GTX.
Find a T3 hybrid, custom piping, blow-off valve, custom header, custom ECU, fuel upgrade, ignition upgrade, stage2 clutch, maybe other thing that I don't remember.
For about 4000$ US, you can have like about 350hp.. safely!

I think it's because you can get a entire GTX for $1000. By the time you buy a manifold and Turbo for just a few hundred more you get every thing.

 

[SyStEmDw]

Yeap, but with a T3 hybrid turbo is bigger than the stock turbo on the GTX.
In the end, he'll have spend about 400-500$ more for that, but he'll have more potentiel

 

[escort_waat_69]

ye so i raelly have acouple options i can just turbo the factory EGT motor, which manifold and turbo should i use, the manifold off of a GTX and bolt up a bigger T3 turbo?

 

[Jeffescortlx]

The GTX does'nt use a T3 flange.

I'm planning on getting my EGT turbo project underway in a couple days. I'm using some parts from a miata... the parts market for miatas is much better, and since we use virtually the same block, many parts are compatible. The stock engine in the EGT (BP) has higher compression and different injectors (among other minor things).

I'm planning on keeping the stock compression of the BP and running 96 octane or possibly airplane 110 octane fuel to avoid detonation. Most people think that you need ~8.0:1 compression, but higher compression and different tuning techniques keeps the engine more responsive and gives more usable power.

 

[escort_waat_69]

which turbo will be best to bolt up to the BP? what octane fuel is best to run

 

[Beaverboy]

The downside to higher compression being that you're more limited to high octane fuels.

Anybody know if the BPT engines use anything like oil sprayers or have any other internal differences that allow them to handle more power?

Siragan, have you researched Toulene? If you have any questions, Uncle Scotty over at NASIOC has been running an overboosted WRX for some time on toulene mixtures.

Even though higher compression forces you to use either:

1. Toluene/water/oil sprayers
2. High octane fuel
3. Retarded timing

the potential for power out of higher octane fuel is HUGE compared to lower octane fuel. Most people forget that part. The tuning and pain in the ass it takes to get 400hp out of 87 octane can be had almost eaisly out of 110 octane. Is it more expensive? Yes. Nobody said that turbocharging was going to be cheap. I do have plans to tune it so the low end of the engine is very mundane and tuned for relatively good efficiency, and the top end hauls ass.

The stock GTX (BPT) engine doesn't use any oil sprayers or anything as far as my knowledge extends.

I may do water injection in the future... right now - just due to the availability of parts - I'm planning on basically hooking up a spoolable turbo, meaning I'd like to get the manifold hooked up, along with the turbocharger (I'm using a T3 - I know it's not the best choice for the BP but I love turbo lag), and of course doing some fancy custom exhaust work with the TIG welder, and also hooking up the oil lines. I'm not going to be driving the car again until next may, so it doesn't really matter that it's not complete.
