Gus, Glad to see you're making some progress on it!. the exhaust manifold looks great!

Whats limiting you on size for your dump pipe? Room?

The bigger you can go the better.

Free power in that alone.

Yep, had to go down from 5" to 4".

rx72c 12-22-09 03:05 AM

Fair enough. 4inch is still good.

5 inch would have been ideal..

Should still do the job:)

mrb63083 12-22-09 06:32 PM

this is awesome...

turbotoaster 01-15-10 11:18 AM

what sort of port does this car have, ive looked through the thread and cant find it

edit no problems, just looked at the broken plate properly and see its a street port, good news for me then as im doing the same :)

enzo250 01-15-10 10:32 PM

IF your still worried about spooling, My brother's FD runs a completely stock "unopened" motor and has no problems spooling..

gusfd3s 01-20-10 02:45 PM

finally i could work on my car! started on the ic setup..

modified the ic..
http://transport.molnsatra.se/bil/2010/10.jpg

you should! they are working great, a pita to weld on though since the flanges are made from some crap aluminum... they are the cheaper pegasus ones, you can find them on ebay...

finished the piping today...

if you look closely you'll see that the radiator is already there :)

Erdin 01-23-10 06:42 AM

just wastegates and oil return from turbo left.

then i have a new motor to build and some ecu wiring..

datsun1200 01-23-10 09:19 PM

Nice work what are your power goals with this setup and what standalone are you useing did you machine you iron's and housing's for doll pen's.You should get the pica motor import doll pin's there not that expensive...

gusfd3s 03-05-10 01:12 PM

Finally i got my gates so i could do some work on the car.. the turbo setup is almost finished, just some minor port work and some coating..

Nice to see Gus! You are really fast when you have the parts at your hands "lol" Some port work tomorrow?

/Lasse

turbotoaster 03-05-10 11:24 PM

yay!!! been hoping you were gonna kick back in with this, ive been following your car very closely and my car is pretty much based around your findings(turbo, porting etc) you going for bridge this time?

Im staying with the same ports actually.. there's plenty left!! going for 30psi this time :)

turbotoaster 03-07-10 10:47 AM

awesome, my setup is going to be identical to yours but ill have stock inlet, racegas and pre turbo w/i

What type of dyno was this done on, does it over read like dynojets or more realistic figures like we get in europe, just wondered if you had increased the number to show what it would do on a dynojet because thats what most people on this forum know

the numbers were made on a rototest hub dyno! this time we'll be running the engine on a superflow engine dyno.

when is your setup ready?

cool, just had a look at a few dyno runs for that rototest, numbers seem pretty accurate actually:nod:

so your running it on an engine dyno, thats awesome, ive never seen anyone run a 13b on a engine dyno before, should give really accurate results!

My engine is build and just finished running it in, got my intercooler and rad setup, just waiting to get a few more pennies to book in for my turbosetup, all fully designed, probably 3months time assuming that everything goes to plan.

Im wanting 700bhp at the flywheel, by looking at yours, since im using racegas and standard inlet ill probably need 28psi i would imagine.

Though im going for a 5inch downpipe to a 4inch side exit which might help as much as yours did

tegheim 03-21-10 05:29 PM

nice! Drewling over your TIG :D

gusfd3s 04-03-10 01:24 PM

finally i've got all the things, starting to get everything together.

back, middle and front plates in this engine was junk irons that were earlier over-ported, leaving the side seals unsupported.

they are now welded + resurfaced + hardened. now ported to fit the rxparts lower 4 barrel intake (cosmo size). we'll see if this works...

side seals are going in the rotors

Could you tell us more about the welding? are you saying you over ported the engine and then added weld to build it back up?

I got the over-ported irons for free, so i thought i'd try to fix them.. what i did was to build it back up again and then port it right. I did a few trashed irons first and i think it ended up pretty good. i will get a picture for you next time im in the garage.

gusfd3s 04-03-10 03:18 PM

i found a pic in my phone,

here is a test iron that i did. sorry for the big pic..

Erdin 04-03-10 04:04 PM

Wow, that's some good work, well done:) You could probably do that if one was to port into the water jacket also. I was told that you couldn't weld the side plates, so its good to see it done! Excellent.

dguy 04-03-10 08:12 PM

I've seen hit or miss repairs with welding, I hope yours hold up.

How much do dual gates really affect spool with the s475 in your opinion?

only tried dual gates with 475 so i cant tell..

gusfd3s 05-23-10 12:14 PM

i havn't updated this thread for a while, been very busy with work..

today i almost finished the new motor, just some minor things left, took out the old one and started to assemble the manifolds to the motor..

i also got my autronic so hopefully the new motor will be in by next weekend so i can start wiring everything!

i also bought a new radiator from a rx7-fc which isn't as wide as the fd one but it turned out to be to high instead :( i had to cut about 4 inch and weld it back together .. now it fits like a charm :nod:

big thanks to my friend lasse wankel for helping me out today :icon_tup:

Thanks for your input Ernie.

It seems to me that a properly divided single gate design will yield the same spool results as a dual gate design. Not to mention less costly, less complicated and and easier to tune in my experience.

Nice to see the new post gusfd3s, keep up the good work!

Islander 05-23-10 02:07 PM

Nice work as always man. Get that thing done and post up some numbers..
