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

 

That'll work.

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

 

how much HP does a FMIC open up?

 

Watch me dyno over 300 without a FMIC or standalone....

 

You'll be generating an awful amount of heat with the stock top-mount core. Be prepared.

Yes, I am aware of that.

*edit*

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

 

those modifications are good

 

im trying for hp without the fmic and standalone also cuz of $ issues

 

Stock tmic core was used in a custom air/water IC.

 

I dynoed 290rwhp on stock TMIC... gonna shoot for 300 as soon as I get the EBC in. I'm gonna do FMIC eventually though... and shoot for more power

 

Yeah, I spoke with BDC online and he gave me the specs on the IC. Very cool.. I am thinking of making one.

 

I put down quite a bit on the stock tmic......
298whp to be exact.... I think it had a bit more in her too

Im going for over 350whp after i GET a frontmount and some more fuel..

wont be long and ill have some numbers to toss around too.. yay for me.

 

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?
