I can weld alright myself but i'd have my buddy do it he works at a metal shop and is basically welding 80% of his shift, he can lay down thos perfect stacked coin welds everytime it's amazing lol

 

I have a high compression 6 port turbo.
Theres 2 schools of thought on turbo engines. 1 is low compression high boost which has its benifits. The 2nd is high compression low boost which also has benifits. DO NOT exceed 10 psi on a stock 6 port turbo and never run low octane gas. Besides that it has more low end and spools faster than a low compression 13B. On your turbo oil feed line use a -4 an fitting and install it where you want but put a restrictor inside the supply line or youll get too much oil to the turbo and it creates other problems. I used a piece of 3/32 brass rod and drilled a tiny hole in the center like .032. David Lanes GSL-SE is a high compression 6 port turbo and its a scary fast car. He's also very helpful if you email him. Do a google for David Lane RX-7 and he has a beautiful site with pics and his emai. I am using a Cartech turbo kit designed for a 2nd gen 6 port same exact thing as David. Hope I helped ,if you want to know anything specific just ask,Shawn

 

ive done this except i have no way of having a standalone tuned by someone since i live in the worst possible place! im going with an rtek 1.7, afm and boost pressure sensor from a tII so that i can turn my boost up to 12lbs. and have the timing retard also. plus the rtek will retard the timing another degree anything above 9lbs. im also using a safcII and wideband to fine tune as soon as i get the lean problem after 5,000 which im hoping will be a kinked feed line or filter for my fuel. maybe ill get a walbro for saftey since im using a fd fuel pump.

 

I'll be running aeromotive fpr,warlboro pump,t2 ecu,boost sensor,maf,550 primaries,720 sec,wideband o2,super afc2,s4 turbo w/custom manifold(by yours truly),fmic,6port street ported motor and intakes,external waste gate(not sure if I'll use it yet). It's exciting,I've built a few na's but this is my first turbo.

well i'll be tuning with a wideband and a safc, same method we used on a civic with a procharger we tunedit into the 12s with stock ecu and only a fpr and bigger pump, totally different car i know but i think we can make the tuning work

 

you could although i am having small issues with the stock ecu

 

what issues are you running into?

 

if youre going to run the stock s5 turbo you could let the primaries stock and upgrade the secondary injectors to 720cc or 850cc thats my opinion and the higher psi i would go with the stock turbo would be 12 psi i wouldn't pass it from there. although theres a guy here a friend of my brother that have a TII and he is **cking crazy you can tell this is BS but i know the guy and hes running 21 psi on stock turbo(and stock intercoller) with a RB turbo back and a microtech. the guy's nuts i dont know how the hell that engine hasn't blow up yet.

 

According to rb if you're going to run boost with an na ecu you should retard the timing because the na ecu doesn't retard timing under boost like the turbo one does. I'm pretty sure 3 to 5 degrees would be a safe bet. Don't quote me on that though.

wow this thread has helped me greatly with my N/a project thanks alot guys,totallimmortal make sure to keep us updated with you project

 

i'll try to keep everyone as updated as possible i'm glad to be getting so much positive feed back a few years ago if you mentioned turboing a 6 port most people on here thought you were crazy or an idiot.

Anyone else have any timing tips? as stated i'll be running about 10psi with a stock s5 turbo and upgraded fuel pump (still need input on that aftermarket, turboii or FD?)

SO lets try to narrow things down a bit heres the parts i'll be useing if i list more than one then please give your tips on which one i should use

1)Intake Manifold
I'll be using a turbo one but which should i use S4, S5 or FD?

2)Turbo
Stock S5 turbo with stock manifold (possible ported wastegate?)

3)Fuel ( i need a little more help here)
I think i can keep the stock primaries but shoulld i go with 720 or 850 secondaries? and which pump? turboii, FD, aftermarket?

4)ECU
Sorry for those of you who think i should go standalone, I WILL, but not yet for now I WILL be useing the3 stock s4 na ecu with a SAFC

5)Intercooler
Some decent front mount medium in size

6)drivetrain
Turboii tranny, driveshaft and rear, anyone know abything about the rb clutch that fits the turboii tranny and NA flywheel i know its a solid hub and worried it may be a little to aggresive for the street

 

Did you know the t2 ecu plugs right into your na harness? Just need the maf and boost sensor. Lot less stress for the timing setup.

my issues are running rich at idle. i have the safc but it just wont regulate the fuel right. after it warms up its fine. another is doing 50 mph and dropping to 2nd gear it gets so rich it spits and sputters unabling me to stay into second. im using 550 and 720 on stock boost. im sure its cause i have so much fuel and all that. this is why im using the tII ecu so it run cleaner without the hiccups. it does spit and sputter when i try to take off from a roll to but only slighty which again is the damn ecu im guessing.plus the tII ecu will control my timing. you should invest in one alon with the afm and pressure sensor untill you go standalone, itll run much better and no need for messing with the timing. im also gonna chip it into an rtek 1.7

 

any downsides to running the tii ecu?

 

wiring it up, it has a knock sensor circuit, and a fuel cut etc. it'll still never be a standalone, which is what i'm waiting for . . .
Megsquirt n' Spark, or Haltech maybe

 

totallimmortal: Probably should port the wastegate, the turbo is out of the car anyways, good time to do it if any. For my setup I ran 550cc primaries and 720cc secondaries and ~9-10psi on a s5 hybrid. Sorry I can't offer any advice on whether you need bigger injectors as to i haven't made it to the dyno yet because I broke my transmission (so your plan to upgrade to TII driveline is a good idea).

 

i dunno why some of you guys are scuurrred to run over 10psi on n/a motors. with the tuning straight, you'll be fine. just keep close attention to egt's and intake temps as well.

i've had alot of success running 16psi daily on my 9.4:1 12a which has over 150,000 miles.

 

This has got me wanting to try this myself. I have a spare 91 n/a I was wondering what to do with.

 

Most hardware stores don't carry the 1/8" BSPT fittings needed as the stock threads are NOT NPT. You need to go to a hydraulic store.

Might as well get a J-Spec TII engine if you're going this far and don't want to keep teh NA stuff. Also, FD manifolds do not fit the FC without spacers and modification. The TPS on an FD is also incompatible with the FC's ECU.

Like me? But I don't need to chime in, since this has been covered 10,000x since I did my original project.

Honestly it has been discussed so many times with so many different combinations that there is LITERALLY NOTHING LEFT TO SAY.

 

Aaron's homepage has a good writeup w/ pic's

 

i dont think you really need the knock sensor wired up. itl run fine wothout it i believe. yes it hit fuel cut with a tII ecu thats why im going rtek. just chip the ecu then sell it when you go standalone. no need for a fcd more timing retard after 9lbs. and it should run hella better.

 

well i may look into a turboii ecu but i might not waste the money on it ssince if i can get the car to run alright on the stock ecu i'd rather sav up for a standalone, megasquirt is prertty cheap right? As far as aaron's page i've looked at it many time over the last 2 years and have decided to do a different setup so his page willhelp with some but not all i need to know. As for this being cover a thousand times, i know and thats why i want everyone to get to gether and get everyones best idea cause wwhen you search you find about 10 completely different answers to every question i have and many things i've found in search have proven to be bad ideas later and i'd just like to have a really good idea about what i'm going to use for every part so that this car will run right

 

Talk to Slick Willie on here.

 

i was also wondering how good the stock top mount is or would i be better off doing a front mount?

 

alright well no response to that but some research and the fact that heat rises kind steer me toward a front mount could someone suggest a size that would be right for aabout 10 psi but still ok at 15 or so i just don't wanna get somethin too big
