well i bought my friends 87 rx7 turbo 2, he blew the motor 2 years ago an sat it in storage. he bought a 3 rotor 2 put in it an lost interest, so i bought the car complete minus engine, i have all the stuff 2 make it run minus a engine. the person i bought it from has a draw through turbo set up, need options to make my mind up

Rebuild or just buy a JDM engine.

yea where would i buy one of the jdm motors an does it have to be an s4 turbo 2, what are my choices for engine, can i get a na 13b an put my turbo 2 stuff on it an put it in my 87 turbo 2 shell, an if some one wants the shell i can make them a good deal. so i can start with a running car.

It doesn't have to be an S4 engine but it is a lot easier putting it in. You have to deal with rewiring the S5 engine if you decide to go that route.

savanna 7

but is it possible to , put a s4 n/a engine block an all the components i have for the car an make it run, an how much do jdm engine run for an where can i get them

I wouldnt suggest getting a N/A engine to turbo it. I would just find a decent S4 Turbo II and it will be a clean swap.

savanna 7

thats what i was told, where would i find a clean s4, the one i have seen needs a rebuild , been left out with an open intake, an where do i find a jdm engine

Well its always good to check classifieds, Ebay, Craigslist.
Ive never seen an RX7 in a junk yard but you could check there too.
You could always check on here too. Lots of guys sell there stuff on here.
Ill be heading to the darkside in due time, So I should have a running S5 N/A for sale.

savanna 7

yea i c, so i think im gunna hold out for a running s4 turbo engine, cuase i have all the stuff to make that engine run, the car i have is complete minus a engine

There are quite a few S5 Turbos on Ebay right now. Just search RX7 engine.

savanna 7

yea thanx there a guy selling a s5 turbo for 80 on here i think, an difference in the turbos that would be a problem for the s4 ecu, an what is you opinion on a carb turbo set up

GordiniRX7

iTrader: (10)

Did you mean $800? If you could replace all of the wireing, the I would just use an S5 carb.

savanna 7

idk i think it was ebay they had a stock s4 turbo,

It would be your best bet to wait it out to find a decent, low milage S4 turbo motor.
They are also better platforms for reasons that I cant remember.

savanna 7

lol. yea thats what i was going to do , what stock turbo is better s4 or s5, an how much boost can a stock turbo an engine take , cuase the car comes with a hks boost controller, n turbo timer

Im gonna swallow my pride and let someone else answer that question. I really havent tested them that much. But I can tell you that I think S5 would be a better turbo, on a S4 pumpkin.
