s4 na to jdm s5 tII
hello, my name is mike and ive been building my rx7 for over a year now on a budget of zero dollars haha. Ive been interested in rx7s seince i was a kid but never had the knowlege or money to do anything about it. late 2010 i decided to go to nascar technical instatute in mooresville, NC ( its the same as uti but with nascar engines). when i got there, i found out that the school didnt teach about rotarys:(. okay now on to the car. i meet some cool people and they motivated me to get my dream car, so after a few months of looking through craigslist i found my 87 na with out a engine:). i was gonna find a s4 tII origanally but a friend talked me into a s5 ( this was the first mistake). the second mistake came right after when i ordered my engine from jspecauto{dot}com. they claim to do a compression test before shipment so i figured it would be alright. 3 months after i ordered it a rep finally called me and told me they had my engine ready to ship and it had 80 to 90 psi on all CYLINDERS:scratch:. well, i thought maybe he just didnt know what he was talking about and a real tech did the compression test. finally the engine comes in, i paid for lift gate but didnt get it. luckily i had good friends to help me haha. 3rd mistake, i didnt check the compression when i got it:banghead: i just put it in the car and started buying other parts for it. okay im done typing for now i dont feel like downloading spell check so sorry for my stupidness. now im gonna try and post some pics, maybe haha.

update!
well she finally starts up now, but wont idle on her own. i removed the BAC and all emissions and did the throttle body mod. ive been adjusting the idle screw with no luck and then it started reving on its own once i pushed it past 4k. any ideas at this point will help a ton!

well it was a vacuum leak :weed: and it idles now. im not getting a vacuum reading on my boost gauge though. im gonna put a little silicone on my throttle body spacer tomorrow and see if that helps.
here is a short vid! http://flic.kr/p/br8dsk |
Looks pretty good. I like the white and black you got going on with the engine, keep it clean! haha

well i got my idle down to about 1300 but still not seeing any vacuum. i have a autometer boost gauge and its pluged in after the TB and i know it works. im gonna find a smoke machine soon.

Love it...now i wanna turbo swap

Where is the gauge plugged though? A good spot is the top nipple in the front (behind the alt/water pump).

well i striped out some threads on my water pump housing while replacing the thermostat so i had to remove it and tap it. finally put some coolant in it and let it get warm, then i noticed a lot of smoke coming from the turbo and turned it off. it looks like its just coming off the hot side and it doesnt smell like gas, i think it maybe carbon build up but i dont know! i just ordered some injector grommets from mazdatrix maybe they will help my vacuum leak, plus they need to be replaced anyway im scared of fires haha. this video, if you can view it, is the smoke coming off the turbo. i shot this about 5 minutes after turning the car off. i just dont know if i should worry about it or let it run and get it all out. its a really shitty video http://www.flickr.com/photos/75346271@N06/6918050325/ also im thinking about getting a magnaflow presilencer or something to put in place of the resonated midpipe on this corksport exhaust. i live in myrtle beach and the locals and police are used to all the motor cycles and bike weeks we have, also we dont have any inspections so im not worried about getting in trouble but i would like it to be toned down just a tad! i know i should have went racing beat. i see alot of cars that have no cats, and they are loud, but they dont got shit on rotarys! haha |
Awesome build man! Same I did to mine...well minus the rebuild. Definitively makes me want to do a rebuild though. My Sunpro gauge doesn't read vacuum either Reads boost fine though. I thought it was just cause it was cheap but I guess not. Weird.
|
well, i took the uim off today and replaced the injector grommets. my old ones where hard as rocks! she started right up for me and idled at about 1400 rpm (cold) but it was solid and sounded good. ill ajust the idle and check the tps tomorrow. my vacuum gauge still doesnt read vacuum :scratch: but i hooked up my brake booster and it works fine.
here is where my gauge is connected to the uim http://www.flickr.com/photos/75346271@N06/6790537928/ now i need to figure out if i want to try and make this power steering work or just go for a manual rack |
wow looks good man your black fc looks just like mine they look amazing in black, and I love the engine set up to:icon_tup: I wish I could be emerced in my Rx7 projects 24/7. How does the rtek7 work would I have to send my ecu out do that?
