I know that im new to the forum but I have been reading many posts for the last few months. Heres my current setup and I appreciate any comments on things I could alter or should be aware of before having it dyno tuned. its a 93 5 speed

The engine was recently put together with a half bridge port according to the previous owner. Also said to have 3mm seals but I cant verify it
turbo is a 60-1 from innovative turbo systems
using 850 secondary injectors in the primary with 1600 bosch in a custom rail
intercooler is hks that is 24x12x3 but wasnt designed for the rx7 so custom 3 inch charge pipes are being fabbed
hks racing blow off valve
its delta wastegate
koyo radiator
walbro 255 pump
rising rate fpr
aem ems computer
second oil cooler in the r1 location
greddy compression tube
oil pressure gauge
oil temp gauge
boost gauge
still havent decide on what electronic boost gauge yet
also considering getting a wideband gauge from aem, but not sure i need it as the tuning shop will use one to keep everything under control

My thoughts were to tune it for 18-20 psi of boost since i live in arizona which has extreme heat.

From what ive read in other posts this should be enough to get safe reliable horsepower but any thoughts from others would be nice.

Only other question is that it seems to me that I am going to need to route my charge pipes under the radiator to make things fit, but I havent seen one car on hear that has done that. They always route them in front of the radiator and over it. Is there a good reason for this that I havent thought of?

Sorry for the long post but Id like to have it bolted up in the next two weeks so I can get it painted.

 

i have the aem wideband and its nice just to see where your at ALL the time. have you looked in to aem's boost controller gauge? i think thats what im going to get next.

 

Offtopic, but I wouldn't trust anyone but Tony at UMS tuning for the AEM unit on your car..

Might want to consider auxiliary injection for 20psi on pump gas, personally I would run a bigger fuel pump also.

 

he was the one doing it for me actually. He tunes my buddies race civic and told me that the microtech currently installed should go for the best results. Is it possible to run two fuel pumps without problems before the fpr or am I better off scrapping the walbro in leu of something more powerful. I'll also likely have 8an lines in the engine bay feeding the rails for both looks and protection. My only worry is that both the sard and aeromotive dont advertise an ability to sustain 90 psi without issue. Plus it would likely be wise to widen the return line back to the tank as without boost it will be sending more back than it does up

One small change might be me going to the powercomander as i just barely lost a bid on the aem for 1000 and can get a brand new commander for 700. Seems like everyone on this site is using the commander anyhow over the aem.

 

6 an lines will be fine for feed and return. you should get a larger pump, like a bosch 044. and you most deffinately need AI for those boost levels or you need race gas.

 

i just talked to tony at ums and he said I could run an inline pump after the walbro, but would have to increase the size of the return line as it would effect the idle drastically with all of the flow at low rpm.

I assume ai is alcohol injection. Not something I expected to use unless i was brave enough for 30+ psi. I like the theory though, keeps things clean from what ive heard and lowers exhaust gas drastically as well.

Keep the thoughts coming as I appreciate the input. My last project was a gst eclipse where my impatience melted a head and it grenaded.

 

AI is auxilary injector. Such as water or meth, which you WILL need for those boost levels. Or a higher octane gas. Such as 104 or above

 

where and what size injector would you suggest? i have seen other compression tubes with injector housings but they look to far away from the uim.

 

i have ran a 60-1 at 20 psi with 550cc primaries , 1600cc secondaries, pump gas 98 oct, and NO AI
withouth a problem
BUT this does not mean you will have same results , best bet is to keep it safe , get the wideband , if youra a guy that "punishes" the car a lot , then i would say get the AI for extra safety , but in my case i did not run 20 psi everyday with the car low boost was 15PSI and high was 20PSI (only when i needed) and i never needed the AI
one thing i do live by 100% , is a wideband ....get one !

 

I would want AI beyong 16-18 psi of boost..... if not, de boost. 96 octane fuel wont be happy at 20 psi with no assistance....

 

I wouldnt go above 15 psi on pump, given the extreme heat.

 

when is say pump i mean 93 octane. also you do gain power with the AI because of the lowered intake temp charge.

 

ill just get a good ai system as i really want to be able to push 20 for the extra power. Most of my driving will be at night when the air is a bit cooler so Im sure that should help a bit. Plus Im getting a system to spray the intercooler as well. Id like to have it were i can go to 25 or more on race gas for my random quarter mile times. Ill just have to see how it performs on the dyno and listen to my tuner as to what he thinks is safe.

 

Its quite simple to setup a system, no need for anything fancy...

 

Why a rising rate FPR with a standalone?



James

 

maybe thats not the correct terminology for the fpr. it just raises pressure at a one to one. i did see some fpr's for na vehicles that didnt have a fitting for a vacuum tube so i just assumed all that had the tube were considered rising rate.
