hi ive looked through the site and its very helpful ive tuned lots of japenese cars and now it time to start on an 1995 rx7 i literally am starting from scratch and no nothing about these cars but through wat im leaning im going for a 20b engine i have pictures below id like confirmation that thats the correct engine i want im aiming to build a 10 second ish drag car with around 600hp can u confirm i ent purchasing the wrong engine thats in the pictures many thanks and if u have any views on wat turbo to go for ect id b glad to hear your opionions

ps any fabricating ie manifold ect wont b a problem so most custom stuff can be done easily thanks in advance for your help


3 rotory 1
3 rotory 2
3 rotory 3

 

easily a 10 second car with stock internals, stock manilfold and a single turbo on Pump gas!!

 

A turbonetics T72 will be fine with stock ports and internals. Use fd rotor housings if you plane to rebuild it. You'll also need a 50mm or larger wastegate to handle the boost. Also if it's a dedicated drag car the stock transmission will not tollerate any launches with sticky tires. I personally don't have any dealings with these people but this is what i'm looking into.

cheers for your reply's guys i wud b going single turbo for sure wat can the standard gearbox take then i was planning on using the standard fd one for a while enless thats out of the question

 

o and also in the pics is that the engine i shud b getting?

 

Yea, the engine in the pic is the motor of choice. If you can find out what # it is. There where some issues with some of the early on 20b motors. Here's a link you can read.

Also if you don't want to outdo the stock tranny stay with the stock twins. I would think that the tranny would be able to handle those okay.

if its' going to be a 600ish horsepower car the T2 tranny MIGHT hold up for a bit.

the numbers sillbeer is speaking of...Anything Bxxx or higher is safe there was a bunch of 20b's 0001-a? that were older and less durable. Not all are bad and there are many A series or older making power consistantly but why risk....

If you go single turbo a t72 to t76 will put you up around 600hp at 15-18psi w/ stock ports and great tuning (tuning is key as we all know). Personnally i went w/ a gt42 ,best buy in my opinion 950.oo plus shipping.

20b in an FD..mounts and subframewill cost ya, the rest is parts and piping.

do your homework on EMS' find a tuner that is local that works w/ your EMS, just a tip

OH and sell everything you dont NEED! this is going to cost you!
Im about 10k into my project w/o an IC,Rad, Fan(s),piping and tuning

 

haha thanks for all your advice i'll b learning for a fare bit longer i recon i want to go for well over 600hp but i dnt want to be unrealistic with cost ive just spent over $30k on one of my nissan pulsars and really enjoyed the car but i want to go back to rwd cars and the rx seems the perfect option as they get off the line really well

i can get the manifold and all pipework made for nothing so that keeps costs down if any of u guys that have done the conversion have a list of all your parts inc injectors to turbo's id be interested to see wat is involved in the whole big hp change because like i say im very new to these cars so any ideas do' and dnt's wud b apreciated
