Hey, guys I just registered and wanted to introduce myself...

My name is Justin. I dont own a RX7 but would like to buy one ( when I'm done with my other projects).
I love the way a 89 to 92 RX7 GenII Turbo looks like ... especially with the JDM rear tails...

well, I have a couple of questions ...
1-Whats the difference in the 13B in the Gen II RX7 and the Gen III RX7 ???
2-How much horsepower comes stock with the Gen II motor???
3-what would your first major modification to the engine???
4- What size turbo does the Gen II come stock with ???

I guess thats it for now... Thanx for the answers ...

 

welcome to the rx7 world............or almost, not to be mean to you but those questions are asked in here pretty much 5 times a day in here. Theres a search button somewhere on the page, just search. I think the 89-92 Turbo II's came with about 200hp to the flywheel (mostly referred to as fc's) and the 3rd gen goes to about 260 (referred to as fd, but im not sure, can someone confirm) The second gen is divided into 2 parts, 86-88 (series 4) and 89-91 (series 5). Your first mods would be intake and exhaust, then go from there, it really depends on what type of increases your looking for and what type of $$$ your willing to dish out. Good Luck

 

1986-88 n/a 146hp
89-91 160
1986-88 turbo II 186
89-91 TII 200 hp
3rd gen 255hp Twin turbo set-up
before you mod....make sure that the car is up to good condition, new plugs, oil, oil filter and all that before modding. Intake and exhaust forsure as a first mod.
