Matt's T2 FB build (pic heavy)
#31
so im going to do some out loud brainstorming here.
i had a thought today. since im trying to keep my fb as my dd as much as i can during this swap i was thinking i could rebuild the 13b turbo and put an early 13b 4 port nikki setup on it and mount it in the car. then i can break it in na while i setup the fuel system and such. i figure it will split my project into 2 or 3 parts. thus giving me a lil less to accomplish each step so i can continue to drive it as much as possible.
Basically.
Stage I
mount engine & t2 trans
custom driveshaft made and installed
dd 13b carb
stage II
build and install megasquirt
modify fuel tank for high pressure fuel system
swap the s5 tii intake and fuel setup
daily drive efi na 13b
stage III (after basetune)
install turbo
build exhaust/intercooler pipes
tune
anyone see any reason why i couldnt run the 13bt with an early carb setup? i guess if i cant id just combine stage one and two.

PS your 3 stages are good plan. I will list another option for your fuel system.
In AU efihardware make a surge tank that is so easy to install all you need to do is use 2 self tapping screws into the chassi rail.
That allows you to return the top of the surgetank 5/16" port to the factory 1/4" using a simple 5/16 to 1/4 adapter.
You can install a Carter Gold P4594 or larger lift pump either above the diff or above/beside the fuel tank, get some 5/16 fuel fittings that screw into that, you may then have that draw through a cheap $2 5/16 fuel filter, and have it pump through an efi spec metal 5/16 metal ryco or similar fuel filter. Connect that to the factory GSL fuel pickup have the carter pump into the 2nd highest port on the surge tank.
You can then use the factory 5/16 fuel feed line to return from the EFI rail to the surge tanks bottom 5/16 port.
It is easy enough to install a GENUINE (i must insist) Bosch 044 under the floor somewhere there, again you can get screw in fittings to 1/2" and again hose goes straight on.
I replaced the factory 1/4" fuel return with 3/8 metal line, however you could also use 5/16.
My home built and tuned 9.4:1 12A turbo s5turbo highflow runs 119mph down the 1/4 (with no traction and a 3.636 ratio in the diff) with those parts I specified.

However if you were to use a BNR or say a external wastegate mani with around a .96 hotside you can get there easy on stock ports.
Something to consider while you have it apart is, Are you going to eventually upgrade the turbo? If so why not at least clean up the runners and factory cast on the intake. Alot can be done in those runners without changing the intake port timing. Also you might want to look into the exhaust port timing. Do you want to have your turbo spool faster? Then you might want to look into changing port timing somewhat.
All in all it can't hurt to get in there and smooth out some of the sharp angles and do some cleaning and polishing.
Good luck.
BTW nice rebuild kit
I have ALWAYS been happy with the Atkins family.

Those numbers might be kind of pushing it with a stock turbo and exhaust mani.

i know i cant get those numbers on the stock turbo/manifold. ill only keep those for break-in and initial tuning. i will be upgrading to t4 shortly after break in. i guess my question is, can i make 375 rwhp with stock ports efficiently or would i be better off to port it now and not have to worry later?

time for another update..........
got an fd flywheel which ive dropped off to be resurfaced.
installed my front stack, set the end play, and installed the front cover. took apart and cleaned my s4 turbo omp
cleaned up my stock turbo
bought my fd intake manifold and throttle body, just could resist porting out the s5 lim and stretching a few bolt holes in the uim. still gunna pull and the paint the intake manifolds. havent decide what color yet.
and how it set when i left the shop tonight. gsl-se oil pan is painted & installed.
