Ok, I'm getting a j-spec engine and I would like to up grade it to get the most torque possible. My limiting factor will be I want to keep the stock intercooler for now.
This is the plan, tell me what else I need
j-spec S4, S5 or other engine (what would be better for torque?)
Microtech EMS LT-8
upgrade stock turbo (need help here don't know much about turbos)
fuel pump (can I use the stock fuel filter?)
2x 550cc injectors
2X 1600cc injectors
fuel press regulator
do I need a boost controler? can't you control the boost with the Microtech EMS?
Will the stock Rad. with an elec. fan be ok for now?

can you give me a idea of what can be done with a stock engine? Please give me some tips.

I just want to get this car up and running soon, it has been down for about 2 years now......don't ask why!

by the way I have a 1988 10th Ann.

 

get a 3 rotor

 

Get the s5 engine, has a higher compression ratio and revs higher. The turbo you will need all depends on how much power you want. Brian at BNR super cars (his website moved I guess, the url I have is a 404 error) supposibly does good work with hybrids. Or find a local turbo shop and see whats up with them. Get a walbro 255lph fuel pump (got mine from http://www.sportcarmotion.com for 80$ new). And Id recommend a turboxs mbc (www.turboxs.com). And the rad is a shot in the dark. Once you get it together if you think your temps are high then swap it out for a better unit. The koyo rad is a direct bolt in.

 

torque = boost
boost = heat
heat = money

 

I would re-calculate the injectors sizes and if ya want a bigger turbo you will need a better way than the stock intercooler....thats the way it goes
