THE 20B project.

20B front Clip 3500-4500
Engine mounts 250
flywheel and
clutch/PP 1550
Turbo manifold 700
turbo( undecided) 2000
turbo oil/water lines 200
intake pipe 100
downpipe 100
exhaust 570
FMIC 1200
oil cooler lines 200
MSD ignition 900 optional
Fuel pump 200
fuel filters 100
Haltech E11 2000
Sway bar issue 500 TOTAL : 13,000
Dry sump 3000
engine buildup 3500 With Dry sump and Engine Build 19,500.

I think I will throw money into this project in sets of 5000 in four seperate phases in the next 2 and a half years, possibly sooner.

 

i/c piping
wastegate
bov
radiator
.....its all the little things that you dont remember that get ya !!!
plus there are always a few extra surprises that dont cost money but take so much time its frustrating

 

bov =210.oo (tial or....)
wastegate will be large so 46mm or 50mm =4-500.oo
the Rad will run you 3-450.oo approx

upgrade the secondary injectors

 

think about this... sell the stock manifold and twins off the 20b and other stuff. I see your selling your 13b...good idea. sell your stock rad. sell it all! I made 3800.oo clearing out my miata engine bay to fund my 20b-T project.

 

oh ..last thing....
turbo.... 2000 seems right on w/ manifold. It ia all about your HP goals. T72 maxed @640hp for someone @ 14psi(20b ported). My goal is about 6-700 @ 15psi so im looking at a T76 (or gt42). Im looking at flow rates of 90-100. Just some insight as to what i have found. G'luck!!

 

yeah since if you go with a big twin setup you have to run dual wastegates. bov wouldn't slow me down alot.
and I have a fluidyne radiator.

 

yes it is all for sale, hopefully I can get a few grand in total for this stuff.

 

I did some searching and I think im going to go with a big twin T04S setup or a Y2K. Everyting else seems it wont keep up with a 20B. 1.32 A/R was too small for the 20B and thats fricking huge!

 

Good luck man. I was kinda wondering when or if someone had made a parts list for this kind of swap. It's nice to see what all is needed.

 

Don't forget saftey eqipment, suspension and chassis work, etc, if you plan on tracking it.

 

yeah, that chart was a rough estimate, I would have to upgrade the supsenion quite alot to keep all the power under control.

 

Sam, I am about halfway complete'd on my 20b FD just had manifold finish'd a couple days ago DP and IC piping next, still have ECU, injectors, coilpacks and some other misc, stuff to do. Let me know if you need to source anything.

My 13brew is running so well that I won't sell mine when the 20b goes in. I'll stick ithe 13b in my 84 GSL.

 

thanks for the offer. Its nice to know if I run into trouble you are willing to help

 

i'm only going to have 1 RX-7 at a time, so my 13bt will help fund my 20b project

 

Yea I understand your situation. Part of me tells me to sell my stuff as well for funding reasons but, I'm too much of a rotary fanatic. I can't stop figuring out ways to improve my other 7's. Damn I need to get a life.

Oh well good luck with your project.

 

haha, thanks
