ok. noob to boost. not to building cars. so gonna have lots of questions and lots of research ahead of me.. a little about me and my car. im 23 and recently picked up a 94 miata. love the car. but it lacks powa! no point and trying to coax every little bit out the 1.8 while it is in n/a form as it will not satisfy me... i love working and tinkering with cars. been doing it for a while now. car i sold to buy this was a 97 cobra. not super modded but was respectable. im hearing 225ish hp will eat my old cobra up and still be a reliable dd. so im going to put that to the test
ok. things i know.
megasquirt. i need it. i just dont know how to tune. so thats my worry. ill get all this done and will screw up on the tune
i have a tdo5h 14b. has about 10k miles on it and i hear its a great turbo for a stock 1.8. i know its an oddball turbo and most people stick with the t3/t4 style. but i got the turbo at a good deal from a friend who is going with a 20g on his dsm.
im being told from a few friends i need a cast mani as tubular ones crack easy... i have one bud who is a professional welder and builds custom exhaust and roll cages for a living.. he says he can make a mani for it. my question is. is there a good way to brace the turbo/manifold to not crack? i dont think i can find a cast manifold for a tdo5h. and is there a certain steel and thickness that would be preferable to last longer?
intercooler. need to figure out a size that fits and has the inlet-outlet in preferred locations. not looking for a super expensive unit and im being told that the ebay coolers are actually pretty good. so if someone has a link to one known to fit that would be awesome!
rx7 injectors is what im being told i need.
things that are easy for someone who knows to explain.
do i want a higher rated waste gate spring and the boost controller will control lower pressures? or do i want a somewhat weak spring and a controller will allow it to hold more before opening.
plan is to cut corners where i can without worrying too much about reliability.
hearing i may need a restricter for the turbos oil line to save the seals?
ok. budget. tax return total came to 2100 doll hairs and i have 600 saved up. so 2700ish.
bought the turbo for 100 bucks as my friend is being nice and wants to see my car turboed
ill be researching but anyone that can point out threads they know of that have very useful info it will be much appreciated
only pic of my car on my pc right now. soooo adorable
