Modifications for 300rwhp
I have an 87 NA vert. I have transplanted a S5 13bt motor & drive train.
Currently it's pretty stock - and I want to avoid opening the engine and doing any dowling/porting for now for $$ reasons.
To date I have done the following:
- Racing Beat 2.5" downpipe & straight cat
- custom 2.5" to 2x2.25" Y-pipe with straight mufflers
- pod air filter
- bleed valve set to 12psi
- stock fuel pump to 1l surge tank & Bosch 600hp pump
- flushed radiator & replaced thermostat
- large thermo fan
I am still running the stock Mazda computer, but I have by-passed the fuel cut (dodgy! ;-)
I want to work out an appropriate staged plan to achieve 300rwhp.
Here are my thoughts:
- engine management (Microtech LTX-8, new coils)
- new plug leads (Magnacor?)
- injectors (will 1000cc secondaries do?)
- fuel reg (Malpassi/sard?)
- FMIC
- hi-flowed stock turbo
What do you guys think? I have been told from various sources that this should produce around 300hp safely.
I would welcome any suggestions or comments. I am particularly interested in comments whether this is safe for an engine with stock internals and whether there is anything I have missed or should do differently.
Thanks

Thanks Ted.
Any suggestions as to what else to do? Can I go any further without opening the engine?
How much boost can I run without causing problems?
cheers

Arent you the one that made some ungodly HP #s on a stock TMIC?

Ok I've decided to go with the stock turbo for now. I will install a Microtech ems, run larger secondaries & a malpassi. With a front mount, that should put me at around 275rwhp.
Then I will go for a T04/66 and hopefully put it around 350rwhp with a decent amount of boost. I would be more than happy with this if I can manage it.
If and when she blows, which I'm hoping wont be too soon I will then worry about rebuilding, dowelling and all that ****.. but honestly from the research I've done to date, I dont think it will be necessary for that amount of power.
What type of plugs & leads do you guys recommend. I guess the largest leads are the go. Do NGK BRP 9 plugs sound good?
