Is it okay???

[MarsaGSX]

Hello to everyone,

Iam living in Czech republic.. and it is impossible search some stuff in my country on my car.. I have to translate everything and have to check and check.. (sorry for bad English )

I got 2G 95 Eclipse Awd.. Only ONE in my country...
I started with some modying.. some bolt on´s..
I got SBR3500clutch kit, Fidanza Flywheel 4lbs.,MBC set up at 16PSI called "Turbonetics style" it is cheap one from Ebay.. next walbro 255lph fuell pump,Got Denso iridium sparks.Underderive pulley-Megan racing and some port work on mani and O2housing

My whole problem is in 3rd gear.. at this point(3rd gear) Iam glad... when i SHIFT 3RD GEAR opponents go ahead.. Everytime..
Last time-yesterday I run with BMW 3,0i´with more then 250horses

dragging:

Turn Engine 4800-5300rpm´s (Iam first..faster)
1st gear turn to 6800-7200rpm´s
2nd gear turn to 7000+rpm´s(still first,faster)
3rd gear turn to 7000+..(opponent go forward-somewhere between4500 and 6000rpm´s they get me!!)
4thgear turn to ???rpm´s speed 85-91mph
my best time (on watches is something around 16sec @ 89,5...)

Iam Boring!

I think my turbocharger is tired(got 105 000miles on it! befor 5years were repaired...don´t know if was cartrige changed....or which type of repair was done..
Befor Month or two I set my MBC at 16PSI..
Now when I check boost gauge..run maybe 13-14PSI on 2nd gear!


Have you got some ideas what is wrong or what I have to change/modied??tell me some way some list what I have to do to beat some serious time.. for beggining 13sec. .. In future I wanna run less 11sec
Maybe it is standard situation...?
let me know please..

And thank you for your time
Venca

It's just the fact that the stock T-25 is to small and the boost falls off in the upper RPM.

Watch your gauge all the way through 3rd gear and see what happens to your boost.

Yeah they are probably passing you because of the crappy t-25(stock turbocharger) being inefficient in the upper rpms and the fact that you probably race all 2 wheel drive cars. Awd drivetrain loss owns you

I was on test run..checking boost gauge
here is result-(you were right..)

on 2nd gear when hit gas pedal my charger flow 16Psi which got set on MBC and in this time(directly after make 16PSI my boost pressure goes down... to "stock" 11PSI )
in 3rd and 4th is same maybe worst...


...Iam usually racing with 2wheel drive cars.. So that time which I "charge" on star with THX. of AWD I lost on the END..

Now I have to install bigger chargerTO4,FMIC,680´s,MafT,3"Maf,SAFC,3"exhaust......maybe 4000USD + shipping to Czech
after that I can beat some serious time maybe less 12s.??

Just take it slow and do 1 thing at a time. so start out with your fuel system and slowly do stuff. Follow a tuning guide that would probably be best.

After few weeks Iam back with new best speed-
1/[email protected] still don´t know (In Czech we don´t have drag tracks )
my buddie stop on watches : 15,4 @ 96!
And this is what I don´t understand-I checked 1/4,mile list
for speed 95,470 is time 15,059
for speed 91,460 is time 15,040
What does it mean?
or 15,290 @88,080! I got better speed(8miles ) and he is faster!

next about my shiftingo you think could be better if I will shift in lower rpm´s because of my T25 flow at 4500rpm´s 11PSI!(got set 16PSI)
I think first gear 7000rpm´s
second 6000rpm´s
third same and fourth-

Well,Do you have some turbocharger for sale? Wanna buy some slightly used for cheap

i would like Big 16g,but think good 14b will be good for now.Let me know please
thank ypou for time

you might benefit from shifting at 5500 but probably not much. As for buying a turbo make sure you buy a install kit to do it right.
