Ideas for swaps other than a V8.

Yes, turbo heads with hardened seats, larger ports, and Inconel exhaust valves ARE dried up. Of course you can still find wimpy N/A heads all day long. Takes over $500 just to get them to stock turbo head levels.

Esslinger's heads are aluminum, and start at $1500. Not exactly "budget friendly" considering that's what a PAIR of 302 AFR's go for.

Have you ever weighed a 2.3T? It's almost exactly an EFI 302. A carb'd 302 is even lighter.

The Volvo swap is cool, but it takes a LOT more work then you realize. It's also heavy.

Bottom line is, it's a 1960's designed engine, that weighs too much, and has barely any aftermarket support for the turbo versions. It's just all wrong for swapping into RX-7's, and frankly, too expensive to modify period. For the money you have in what is going to be a 250HP engine you could have a 300+HP 302 and still weigh less.

first , iam not picking a fight and i dont have a problem with you.iam just posting the info that i have gotten from restoring the rs turbo capri from the ground up.

Esslinger's heads i agree with you not worth the money.yeah they flow more then a stock turbo head but if you have a good core you can spend less money on a port job to do the same.(depending on the person porting) the reason i say that is because two people in my capri club tested it out. one had a esslinger head and one had a stock turbo head . they both sent them to a head porter and he was able to get the stock head to flow the same amount.

the pre d port heads are extremely hard to find but the d ports are better any ways.my step dad works for jack young auto, they mainly sell to fleet's. like ups, fed ex, the police , cab drivers ect and garages. if you bring your car to a shop and they replace some thing there's a good chance they get the parts from him. when i worked there we sent stuff to cali Seattle ect ect.

we had the stock head magna flux(is that spelt right) and it was cracked. he got the head at his cost for 220$ with cam's and valves 2 days after i asked him to get it.before you ask yes its a real turbo head, not a na. the place they got it from said they had close to 200 ready to be shipped out and more that are waiting rebuild they said they havnt gotten a call in some time asking for one. so there not that hard to find just need some one who can buy them from a ford re builder. most are in Canada believe it or not.

pulse ford racing still sells heads to.

like i said i didnt list all the info on the volvo head swap ive been researching it for some time. its not that hard to do but it can become over whelming fast at times.need to take baby steps. all so i didn't have a scale but from me lifting the Volvo head which is aluminum and the 2.3 turbo head which is iron. to me the Volvo was lighter. maybe it was my mind tricking me in to thinking it.

the stock 2.3 turbo motor made close to 220 hp at 8psi depending on what car it was in.the v8 made a little less the same years the turbo 2.3 was offered. i didn't list all of the stuff we did to the motor.
the motor was blown need to have the deck fly cut and bored out. so i think going from a blown motor to a fully built motor for 1500$ is cheap.
there are a few guys that did every thing we did to our motor and are running
the motor at over 30 psi safely. one person had his car shown in modified mustangs and that where me and my buddy got the idea to buy the capri off the guy i work with and fully restore it. had no floor's ect ect if it was not a 1984 rs turbo capri we would of just got the motor and got a mustang shell.

where not going to run it at that high of a level of boost because we want it street able but well be around 20 psi+
other people in our club are running around 20 pounds of boost and didn't do half of the stuff we did,and there motors are safe. most are making 350 pulse.
the only person in our club that has the same setup but in a mustang is making well over 400 hp rwhp. he took a black marker to his dyno slip to hide what hes really making and wont tell how much boost.

too expensive to modify(i don't believe so).
there is after market support. yeah some things youll have to make your self but if you know where to look you can get it.
ecu= mega squirter, sds ect ect.
intake manifold= 40bob.com or you port and rotate it your self, like i did.
turbo manifold= 40bob.com or make you own. theres a few others making them tho.
custom piston's = diamond.
stroker crank = esslinger, connecting rods for stroker with there crank any 350 sbc which there is ton's of.

i dont have a feeling about putting one in a rx7. i wouldn't put one in my rx7.
i just posted here because the ford turbo 2.3 was talked about.and its not every day you meet some one with a rx and knows about the 2.3 well at least in my age group 22.

again i am not fighting you , i dont think bad of you in any way.
i do not want to start a fight. i do not want to be flamed. iam just posting all the info i have learned from restoring the capri.
