well it's been a long time before i got where i am today with my 3 year old project.
I decided to go turbo but didn't want to do the turbo engine conversion,Wanted to do my custom fab so i followed Aaron Cake's threads to get more idea's for my n/a turbo and the only difference with my motor is the 93+ rotors in the 6port block and this motor is full bridgeported (same as Aaron's but the center plate is also bridgeported ) recently rebuilt with hurley racing apex seals
for now im still running the car on the n/a ecu runs fine starts right up no problems so far but i have some of the turbo parts like the wastegate,Haltech e6x,Blowoff valve till now, on the way is the ebay intercooler kit.
the intake manifold is a TII intake had the lower intake manifold port matched with the 6 port block some what like japan2la's lower intake manifold thanks to my friend for that.
general propose of the car is mostly drag racing and a daily driver.


the only things i would like to get suggestions on are:

1. fuel pump : been thinking of running a single or dual walbro 255lph pump(s) or the single denso supra pump.
2. the injectors : 4 1000cc injectors but i want to get some idea's from u guys on this one .
3. the turbo : been thinking of the t67 with the 1.00a/r for a fast spool and big power on the high end dont want to go with the .86 ar to small for the bridgeport.




here are some picture's of the parts that are already here:














Some shot's of the interior:











only picture of the exterior right now, pretty much stock only difference now is the addition of the Hid kit and the Jdm mirrors will post a new picture later





if you guy's have any Question's or comment's or suggestions's for my project your welcome. thanks

i've used 2 walbro intank pumps, ran up to 22psi on them with 4 1600 injectors with a holset hx55 22cm2 housing. pull up top like crazy. wolf3d ems.

at the time we never dynoed the car it was just street tuning.

looks like a fun project. keep us posted

A quick question do u guys think a hx50 with a 19cm turbine housing will be too much for this project or a hx40 with a 19cm housing found both for almost the same price just dont want too much lag. dont have the budget for a garret Gt BB series
the hx40 is gated but if i weld the gate shut and remove the mechanics would be ok. the hx50 is a non wg version


hope to get some help on this one

Edgar,

go with the 50

A 40 is just going to leave you wanting more.

50 is a good choice but again, you may get bored of it and want more.

Hell, you can run an hx55. People are spooling them on single slam hondas at around 5500-6500 if it gives you any idea of how driveability would be. They're fairly easy to find. I'm a HUGE fan of holset turbos. They're cheap enough and hold resale value well enough that if you dont like the 55 or 50 you can sell one for the other and possibly swap. Register on www.homemadeturbo.com. They're always selling great stuff on there at a great price but always do homework on the seller beforehand.

it say's that the turbine housing is 19cm^2 since you have a good experiance with these turbo's is this some where in the 1.05 a/r ?

rx7fc90

well its been a couple of day's without updates for you guys
it seems the holset turbo's have been sold so now i'm looking at the following turbo options : t04b with 1.15a/r turbine housing and the ta45 with 1.22 a/r housing

need RX7

iTrader: (4)

Nice.

If you insist on using those 6port side plates you might want to look at smaller turbos than the HX55 and the TA45.

rx7fc90

think im going with the garret t04b with the 1.15 a/r housing i also found another t04b with a 1.32 a/r housing don't know if its going to be laggy

Painted a couple of parts ,got my new TII hood,and the new t4 flange







got this in the mail today from a friend , guess i can make a mani out of this and the rb flange its a mild steel T4 flange not diveded just open like the one's from the hks cast manifold's



my dad got this hood a friend over here with a little work on it , now it looks really nice on the car ,painted it matte black for now and its damd light too cuz it's aluminium too






and the old aluminium hood

You're using fd rotors. I'd use an hx40 maybe.

There are so many different housings you can use with a holset chra. Alot of the series (cant name them off hand) just use bigger or smaller housings with the same chra and same turbine/compressor wheels. Holset turbos are like legos. Keep that in mind. Bullseye makes housings that fit holset wheels as well.

Do a search on www.homemadeturbo.com or even check out the holset site and read their faq.
