Pinto/Kent. NA side draughts or Blow through turbo?

So I'm weighing up costs and power output between these two options on either a kent or pinto motor, the reason being both motors are adaptable to twin DCOE's or 32/36 Blow through turbo. I already have both engines with fomoco manifolds and 32/36's and a Garrett T25 turbocharger. But I only have 1x 40DCOE32 weber so the cost of getting another DCOE with manifold, linkages, possible removal of brake booster bracket/ install pedal box etc would be similar to buying a 32/36 turbo hat, turbo manifold, lowered CR (pinto) and associated set up costs?
Any thoughts thanks

    I don't know why ppl look at using twin webers with turbos the cost is just too high for something that is never going to match efi, the air is being forced into the engine from the turbo so no need for 4 throats

    Id imagine the pinto you would get bigger HP/torque results. They just flow more and obviously the bigger capacity will help ten fold.
    Theres a been a few big HP turbo pintos over the years..
    Although the only thing i can see is as the exhaust is on the brake booster side its not going to be as easy to install, where a kent motor you have that whole side of the engine for the turbo/manifold etc.
    But the pic below proves otherwise.
    If i was going the pinto route id get your hands on the sierra efi manifold (see below pic) and just run a basic efi setup. Would be much more reliable and give better results than a 32/36 id imagine but then im no efi expert.. (someone might want to expand here).

    Hell yes that pinto looks the goods. Heavy though, some capri struts and better brakes would be a must $$$
    150atw would be ideal, any more power means more $$$ spent. So I'm happy to sacrfice some HP for money saved + Better handling (kent)

    I am yet to see a successful blow through set up.  The amount of time wasted trying to get it to work correctly is an issue, and it will never be 100% right, everything you do to make it work is a compromise, and generally you end up with rich idle,  and/or lean on boost.  If you want to do it on the cheap use a draw through set up with a holley or an SU and save yourself the headache, or just inject it to start with.

    Thanks for your advice Woz.
    Baccas "turbo roo" uses a 40DCOE in suck through config and it looks awesome. But finding one of those turbo plenums is proving most difficult.

    There is no reason not to use this set up either, it works well.  Any of the y-piece connectors to do it that I have seen have been made which is a pretty straight forward job.

    also if your pricing it up don't forget to price up the fuel regulators and pumps , which will start to add up onto something that may be a compromise also ignition timing will be an issue if not using some sort of computer
     
    sorry about my last comment i misread your original post

    EFI on a Kent motor? Now that would be expensive.
    The link I put up earlier (turbogemini) has malpassi regs and VL pumps in his kits with hi and lo pressure fuel lines etc for what looks to be reasonable prices. I'm expecting a reply from him soon re: pricing for some of those parts

    I'm not going to try and influence you as you know which way I have gone. But what are your goals for the car? Is it going to be a daily driver, race car, etc, etc and go from there.
     
    I went the way I did for a number of reasons. I wasn't after a big horsepower increase. I just wanted something to give me that extra poke when out on cruises, or the freeway where you need to overtake. The car was already built and painted from a number of years ago so I didn't want to go about cutting it up to fit intercoolers or changing the firewall, etc. Most importantly I had all the correct gear sitting in the shed not being used (no re-sale value for a suck through setup) and I wanted to build the car so as to keep it in the era.
     
    Personally I wouldn't try to go blow through as work is required on the carbs to handle boost plus fuel pressure regulators and so on. I have seen some that have intercoolers and ECU's to run them. You may as well go the EFI route. As suggested to much hassle, it makes much more sense now days to go with something more modern like Zetec or Duratec.
     
    The one thing for sure though is once you have turboed it and DRIVEN it, you will never want to go back to carbs.

    Hi Theo, thanks for joining the conversation.
    My car is being used as a weekend warrior and I plan to keep it that way. I'm quite happy with how it is now but like you were,  I'm chasing just that little bit of extra power.
    A Duratec/Zetec conversion is the ultimate but like the point you made earlier about resale, well good luck getting back the 20K it would cost to install and engineer such a project.
    I have a T25 sitting around doing nothing, and a spare 711M bottom end that could have forgies in it :)
    I drive a turbo diesel work vehicle every weekday so I'm quite familiar with that feeling of being pushed back into the seat. It would be great having that in my esky.

    I had a look at blow through but as everyone else said, it becomes just as expensive as efi... i am currently putting together a draw through setup which is much easier
    still costs money but there is less to buy etc... and the fuel mixture is already done so no need to worry about leaning out (well not as much as blow through)
     
    I will attach a couple of pics... this little mk1 was for sale in 2002 and i nearly bought it (not sure where it is now?) but it was running a pinto with cosworth pistons and rods, worked head and a to4b turbo with a 45 webber draw through... it was making over 300bhp to the rear wheels and ran a 11.47 at 127.30 mph recorded at willowbank! sounded like a lumpy pinto.... and drove like one too untill it hit 30psi! :-D this thing is the reason why i am building a pinto draw though... you have a similar car... DO IT :-D

    haha, hey Ty.
    That's one mean escort. The more I consider Theo's first question (my goals for the car), the more I think about using the pinto. It's in pretty good shape and the T25 is probably more suited to it than the 1.6. What sort of transmission was that escort using?
