Boost? Mods?

SureShot

The BOV is the easy part. You have a lot of latitude.
The bigger the turbo, the bigger the BOV.

The waste gate & boost control are more critical.

right now the car is stock.....just an intake.....im just got the car about 4 dayz ago and im starting to buy parts for it......
right now i don't even boost the turbo no more than 6 psi....im afraid that it might break down considering that it is stock....im running on stock turbo and stock everything.....im trying to upgrade my fuel system.....before i push the car.....so basically right now im trying to get advises from the PRO'S OF rotary.....imma work my way to the engine to the suspension....so any suggestions are welcome......

if you have any other advise on how i can upgrade my car......pls dont hesitate to post.....

werwuryoantenaz

so how should i start.......what parts to buy and what parts to upgrade.....im planning to keep the stock turbo....for awhile....thus what upgrade(s) should i do.....?

Madrx7racer

ummmmmmmmm......best BOV is HKS......hands down. but you don't need it on your stock car.....don't be dumb guy.......how will your car break down because it's stock????



first replace all the hoses and vaccuum lines........then make sure no wires are stripped THEN worry about upgrades.

Madrx7racer

have you read ANY OF THE STICKIES IN THE SECOND GEN SECTION???????????? i suggest you do that before posting any more.

Leave the stock BOV. Putting on an aftermarket unit with the stock turbo will gain you nothing except the "pssssst" sound.

As for upgrades, please read the FAQ and take a cruise for the archive. Then do a search for "basic upgrades", "first mods" or variations on that.

Lay the groundwork first. Upgraded fuel pump, S-AFC or other fuel controller, proper gauges (at the minimum, boost and A/F), PORTED WASTEGATE and larger secondary injectors.

Read the FAQs, read the archives, search, and then you'll probably be good to go.

yes thank you...ive been reading it over and over again....hahah....i guess imma go to upgarde my fuel system first then...everything else follows.....

Madrx7racer

oy...........first get the car running perfect.....then modify it.

werwuryoantenaz

i just bought the car this monday...and its been driving really good.....
i have a 10th ae with only 104k on the body and the engine......
runs perfect,no smoke,clutch,tranny,everything else in great condition......
he replace all the hoses,vaccum lines......new alternator, new battery.....new spark plugs....

basically in great if not very very good condition...

what kind of wastegate should i buy......40mm or 50mm....and what brand......
after the waste gate...what is next...

suggestions are very welcome

gingenhagen

no need to buy a wastegate, just port the one you have.

Madrx7racer

you have an internal wastegate.........so you cannot BUY one.....look......IF the car is in as good a shape as you claim then I would buy a boost controler and PORT the wastegate (requires removal of the turbo) followed by fuel pump and SAFC then some 720cc secondaries....and a dynotune to get it running right AFTER the mods.

Madrx7racer

oh and if you have another question type it in HERE

werwuryoantenaz

last thing.....how much do you think it would cost.....to be done profesionally......and how much hp would i gain.....also after this what is next....

Madrx7racer

um....let's see.......

SAFC=200-300+ labor
Boost controller= 50- 400+labor
fuel pump= 100+labor
removal of turbo, porting and installation= at least 6hrs. of labor (you know some mechanics will take their sweet *** time) here a rotary mechanic charges 85 bux an hour and Auto Rand D charges 90/hr I believe.....
720cc injectors= 120-160+ labor
dynotune=500-800 bux for full tune

LEARNING TO DO IT YOURSELF= priceless

you are looking at 12 psi (max you should push on stock turbo) and the HP can range from 240-260 depending on how much you lean it out......some people have gotten 280 out of their stock turbos BUT THAT was leaning it out to retarded levels (13:1 and such)

werwuryoantenaz

damn that requires...a LOT of hustlin........

Madrx7racer

well the SAFC and AVCR (what I have) is not too difficult to install if you can follow directions.....I soldered them into my ECU harness in my old TII ( i still need to install them in my new 7)..........

the fuel pump is a piece of cake just make sure you have enough power going to it......

the porting of the Wastegate (WG) is a bitch because you have to remove the turbo and oil lines and blah blah blah....but you need to do it to avoind a boost spike and blowing your motor .......( I spiked to 13 psi and I almost shat my pants......my friend boosted to 16 psi and blew his motor)

720cc injectors...........well.....it's ok but it takes time.

Dynotune........you HAVE to do it to take advantage of the mods listed...........I'm going to buy a wideband 02 sensor with logging so I can do my own tuning but it will cost close to 400 bux.....
