GT(X/R) imported vs. building a BP
Which would be a better idea?
I have a 93' 323
I live in Dallas Tx, and I found a BP in a 93 Protege, that has 40k mi on it for around $350
Which would be a better buy?
Have a GT-X BPT paid for and shipped (2200+S&H this is in Austrailian money) from over seas and bolted in, or the BP from the local shop for 350, and use the rest to build it up.
any thoughts?
I saw the BPT for sale on this website:
http://www.jaustech.com.au/engines%20-%20mazda.htm
any ideas?
I think that I will end up building up the BP from the wrecked protege for 350, just b/c then I know what has been done to the engine and I know that the miles are more likely legit.

HOLY MOTHER OF GOD!!!!!! That site says they have the GTR in stock!!!
Man, I'll tell you this. If you want one engine that you can get and put SR20DETs and most every other 4 cyl out there to shame, get the GTR! It's the mother of all 4 cyls....factory rally engine (FULLY turbo prepped motor starting from sodium filled valves down to reinforced block). What more can you ask for?
http://www.xe.com/ucc/convert.cgi
It comes to about $3000 (USD) plus shipping and includes "engine, airflow meter, computer, engine wiring loom, relays & ancillaries" according to them. Couple that to a G series tranny with a lightened flywheel and the best clutch you can find and you will be set.
Anything else will cost you more in the final run and still not be equal to the GTR... (including a $350 BP which will need $1500 in just pistons and rods to take more than 6-7 psi boost, not to mention the $2000-2500 in turbo rest of the stuff.)

I'd go with the BP. It has the MUCH higher flowing head design (gave braden like 10 or 20 whp just using the NA head), and is cheap as hell. I'd say build up the BP, but that's just me. You'd want to get the BP head anyway if you got the BPT.
But do whatcha want

There's no doubt that the GTR is an absolutely kickass motor, but I'd say go with the BP build-up too. Like Funk said, BP internals and head flow have been discussed here many, many times. And quite honestly, I'm not sure I'd want either GTX/GTR from the Aussie market anyway. Think about it ... those motors are in the 323 and are usually used as rally cars, or at the very least, as 4x4 vehicles in rough terrain. Also, it's a known fact that most cars there are not well looked after. I've read this many places and most Aussie's I've ever known or talked to readily admit this (not trying to offend). I'd much rather have one of these motors from the JDM.

what you should do is build up the bp, but i'd reccomend getting better pistons that can handle the boost and removing VICS from the intake manifold. the heads off of the n/a motors have bigger inlets, so youd get more power. i have a gtx engine and im just gonna swap the head to a n/a head.

I'm not using stuff i've heard from a friend of my cousin's classmates gardner's physician's mechanic or something like that lol.
I did the necessary research, found out prices of necessary upgrades and parts and did the math. That's why i said overall it's gonna cost more to have a BP to run high boost compared to a GTR (provided the GTR package can be obtained for under 4G). Besides, BP heads are cheap (usually about $100 or so on ebay) and you can use the sodium filled valves, cams and springs from a GTR if you want the additional flow from the BP.
Anyways.... I'm just backing up my recommendation.

LoL funkdaddy, that's one way to reply to my response. (i think....)
I know there are some frekishly fast BP based cars. Why do you think I am so confident with my car? If you scroll back, you will see I was responding to funk's claim that there is an EGT with close to 400WHP using stock BP internals.

The 399whp was NOT on a 8.8:1 compression BP found in a EGT, it was found in a 9.5:1 compression BP from a miata....and it WAS BONE STOCK INTERNALLY. No cams, no headwork, NOTHING. You can search for Ric's posts over on the miata.net board.
