and you didn't want to buy my motor ;) lol Joking Thats a great set up. No offence to Hardcore and Flo But when your running anything 15 PSI+ on a decent size turbo you will deffenetly see a difference if not in whp in spool for sure. You both had small turbo so thats prob why you didn't notice a difference.

and on a side note My buddy that had a Sunfire drag car broke a 80 something mm tb and ordered a moster 103 mm Mustang tb modded it to fit and gained something like 40 whp and about .5 sec on the 1/4 ;)

TB increases spool? Thats a new one.

And sorry, I want to see a dyno that shows a 40 whp increase with just a TB.

well on an other site its the same thing as here ppl who have had small tubos say stock with a port and ppl have been turboing for years say go aftermarket

so im stuck in the middle

GO BIG OR GO HOME ;) With the money your spending on the motor build it would be a waste to put in a smaller turbo. Well if you don't belive me about spool ohh well increased airflow into the motor increses exit airflow incresing SPOOL.

haha im going with a comp ct360 i believe....i can get them really cheap so thats my route

just saving up for the tubo and accessories and ill be ready to start this project

Like I said, show me the dyno #'s and I'll beleive you.

The problem with spool, is that until the turbo is spooled up, you don't get increased air inflow, you actually get decreased in-flow due to the backpressure introduced by the larger wheel.

Of course, spool also makes the STi daily driver friendly under 3,000 RPM, and a monster over 3k.

As for the size of the throttle body, throttle body sizes don't matter as much in forced induction... or turbos.

In the end, boost is a measure of the wasted air in your intake -- it's not a measure of power. Decrease backpressure, take in more air, increase HP, lower boost pressure.

due to the fact that exhaust gases exert more pressure on the turbo, you'll get more efficiency in decreasing the backpressure after the turbo than you would by putting a larger throttle body on.

In my opinion (and it's just that -- my opinion), a larger throttle body would be necessary if you found that your boost was rising and plateauing early at WOT, but not limited by the boost controller. This would mean 1 of two things -- you have excessive backpressure aft of the turbo, or a restriction in your intake -- and once you eliminate the backpressure issues after the turbo, and you're still having boost plateauing issues, then you need a bigger throttle body.

If you were going N/A .. you're engine isn't being force-fed air and needs to sip it through the straw... in which case you want a larger TB.

As for mechanical vs electric gauges -- Electronic gauges offer two distinct advantages -- you can often datalog off them easier, and if there's a leak, they don't leak into your cabin.

mechanical gauges are cheaper, but you can't datalog them like e-gauges, and if they get a leak, then you get that leak into your cabin -- which might be a safety concern when hot oil starts spraying into your interior.

But for basic functionality, they're both about equal.

Good luck with your project.. you're off to a good start.

thanks for clearing this all up puppet..im getting my shop to do the acually swap and hooking all the lines up for the turbo and such they gave me a super good price to do the swap and run lines and such the acuall swap wont happen till aprilish as the car is gonna be in storage so this thread is gonna be pretty dry for a few month :( ill give you guys a heads up when it happens...im gonna try and stretch it out as much a s i can so the thread doesnt go to dry.....STAY TUNED

If your running lines into the cabin and running fluids I think tracks require that this is a hard line. Andrew can confirm this is correct or not.

the car wont be tracked i might do it once to see what i can do its mostly for fun lol but yea cant hurt to run hard lines....

does anyone no roughly how much i shop would charge to do the initial swap???that just taking the old motor out and putting the new motor in ...not building the motor

For remove and replace your looking at between $500-$700

As for running lines into the Cabin yes hard lines are needed but I've only been asked by one tech and that was in the US.

Ford Dealership here was charging the new owner of my old car $1200 for R&R when he blew the engine. Labour only. :ph34r:
