do u think that a suzuki 1300(carb engine, non EFI) Elect. Fuel pump is enough without any regulator, for standard A12 carb.
go-the-datto: -
does Daihatsu T have any internal or external W/G?

Mr nizmo4 I agree most people put them for the sound! ( If I wanted the CHsssshhh! sound I would open a bottle of coke! lol!
I however do prefer the flutter you get without the BOV!)
There is a bit of again you get by haveing a BOV and that is the when you release the throtle for gear changes the excess presure is released and the turbo is still kept spinning so as it with still be creating boost for when the throtle in pressed again!( If you change gear quick enough you wont even notice this even if you dont have a BOV)

I personally feel that it is better without a BOV as when you change gear with a BOV you still have the same boost and this power is going straight on the gearbox! ( Leading to breakage!)

I see it to be a win, win, No win situation!


And like I said and others have said and repeated a low pressure fuel pump it no good! ( You need a hi pressure fuel pump off of an EFI car!)

and what phenomenon is that flutter!!!!
Quote:
u got a point here, as i will b keeping the stock GB and Diff, what benefit besides longer turbo life does a BOV have(dont mention lag).
Quote:
but i asked bent-axel-bob, he says a non EFI should b enough for my application.
anyone else give opinions plz.

Sorry guys, I still prefer the suck through carby setup, you don't have to worry about sealing the carby, accelerator cable and hoses for the fuel supply and so on,,,,a weber or su or stromburg or something that can flow enough air (cfm) to match the engine.
just use the standard mechanical fuel pump which should handle it real well. Power with a t25 garrett should be around 180 Hp at the fly wheel on conservative boost say 8-12 pounds. you can wound it out to 15 pounds but then water and/or methanol injection would be needed to keep detonation down. You really need heavy duty valve springs as this will enable you to rev a little more.
This injection can be made so it only comes on when you hit say 10 pounds. Throttle response should be really good and you don't need a Blow off valve as there is no throttle body in the way. So simple effective and practical, and it looks real cool seeing the carbys hanging off the turbo inlet. Better than looking at a box.
Its also so much easier to work on. Oh and don't use the T2 as the pulsars and exa's usually get a t25 which is better. Besides the T2 would be generating heat at the top end of the efficiency range, which is bad it encourages detonation. And summer is coming....so its gonna be hot.

well, Gragongoose has really given a different perspective, but the prob is that i want a daily driver car, not a strip racer. and all i have is this Hitahi, but i liked this setup for weekends, maybe i should get a new 1200 for this 180 HP beast.
BTW what do u expect my HP will b on OE carb blow through setup @ 10 PSI.
and do u mean that pulsars have T25 OE turbo? or a T2?
and do u guys know what T does a Starlet IC Turbo have in it?
barpk

there is difference between Methanol and Ethanol!!!!
altough both r called Alcohol!!!!!
what the hell does that mean? which one is right stuff? or botth r fine.
BTW how do i make a alcohol injection? can it b done without any pressurized can?
what about windscreen water sprayer?
what about using a Spray Paint nozzle?

BARPK,

All I can say is I have told you what I have experianced with this setup! whether it was good or bad!
Others have told you what they think or experianced too!
If you do choose to go ahead with this setup
Listen to what has been said or don't listen! It's up to you as the only way you will learn is from first hand experiance!
Maybe this is even better as you could try something different and end up with a better result!

first off i have no experience in building turbo motors!

but 180 hp from a standard motor with mech fuel pump and a T25 sounds very unbelievable to me

or

maybe thats not what you were saying but still just bolting on a T25 is not going to give 180hp with right fuel pump on stock motor is it?

Finally someone atleast can vision what I am trying to point out!

And Barkp you cant always listen to Bob cause if you notice he has always been drinking when he comes online! lol!

( Sorry Bob! )

and i forgot, most stock tubo setups have an internal wastegate which blows air somewhere (i cant remember) but back in the motor to vent the air, i cant believe you guys are against the BOV, they are technically a very good thing (you all know why but obviously dont understand the importance) as long as it doesnt have a huge trumpet hanging off it, you should use it.

As far as that load on the gearbox thing, ive never heard such bull-shiet, i mean really thats like saying "i dont want to put a sports air cleaner on cause it will increase my power and put more load on the drivetrain" ( well maybe not that drastic but..) i mean you probably rev the shiet out of the motor when driving hard and dont let the revs die between shifts so why start worrying about that, the turbo still has to wait for exhaust to build boost again and there is going to be most exhaust when the motor is under load (after clutch is engaged) its just the fans in the turbo will already be be spinning quickly from the last wind up rather than going slow from trying to turn in "thick" air, and therefore longer turbo life

but anyway if you think a bov is all wank, good luck to ya
