Currently purchasing a S4 N/A Rx7. I'm building a drift car and need around 400-450rwhp. Would you recommend finding a S5 TII and building it or just going for the 20B. Money is a concern I don't have 20k to spend.

 

if money in a concern then a 20b swap is out of the question. A cheaper option is to find a s4 turbo motor and ecu, rebuild the engine and put it in your car

 

Your easiest path to 450hp is a LS crate engine.

 

I don't want to sound ignorant but can the 13B handle 450rwhp ? Also anything other than rotary is out of the equation. I want to stay true to the design and prove these motors are just as good. Also I noticed you said S4 turbo so I'm assuming you don't recommend an S5 turbo motor then.

 

Your goals seem unrealistic.

Read this thread to see what goes into a 400-450whp drift build.

Look up Aaroncake's Project TINA build - that was an S4 NA-turbo build (so he turbo'd the six port, not a TII swap). That would help give you an idea of what goes into making serious horsepower (and doing so for more than a short while). A lot of planning, a lot of fabrication - and some real money for quality parts and supporting mods, even if you do all the work yourself.

 

Prove to whom?

@Mr. Criss...
What level of mechanical expertise do you bring to this project, what sort of equipment is available? What racing experience do you have?

Ignoring (for now) the debate of how you get to 450hp, after you've climbed the mountain, how do you finance a campaign? I'd guess drifting absolutely hoovers through tires and they seem prone to suspension/body damage- all expensive stuff to maintain, over and above whatever running costs are associated with a high strung rotary engine.

And about the engine...
Seems like drifting would require more torque than horsepower- don't you spend most of your time spinning tires through relatively slow corners?
Wouldn't bottom end be more useful than power up top?

 

Hello,

I've built RB25s with my brother who seems to be pushing where I wanna be but has less than 10k in his motor. I have decent funds, I would like to stay around 4-6k in the motor so nothing insane but some decent change. Correct on the torgue which is why I assumed having a smaller turbo would thus spool faster and sooner so I thought that would be beneficial. Correct me if im wrong though.

 

I would like to add. I came to this forum for I reason, I need the experts and this place is known for that. I'm not expecting to be racing in a week, I want the car ready to go by spring 2017. Which is why I news everyone's help and to bare with my ignorance. Thank you for everyone in advance

 

I have tools or access to the ones I will need. So far my real challenge is finding where to buy everything and how much things are worth.

 

Do you feel 350whp is more reasonable given my budget ?

 

I think your will either need to comprise your budget or compromise your expectations and do the car in steps. A quality rebuild or recently rebuilt motor will be starting in the neighborhood of $2k+. Quality turbo, manifold, and associated parts $4500+. Quality engine management $1000+. Fuel system overhaul somewhere around $1500. Add suspension and you're already busting the budget, not factoring fluids and other assorted parts required when making a 30 year old car road worthy, let alone track ready.

 

Cresting 300 is more realistic. You'll be able to use a hybrid turbo on the stock manifold, saving a lot of cost (both directly and indirectly in relation to supporting mods).

Awesome thank you!

 

Winning!!

 

You may be biased.

 

450hp isn't really hard, you pretty much just need a big turbo. the hard part is keeping it all together, you pretty much need to re-engineer the cooling system, fuel system, turbo, intercooler, ecu etc, and then keep the transmission together too.

the Apexi drift FD was making about 450hp back in like 2001, so its been done, a lot, a long time ago

the nice thing about the FC though is that it can do ok drifting nearly stock.

the S4 or S5 engine isn't going to matter, it needs to be rebuilt and a bigger turbo anyways

 

I'm glad you said this, because that's sorta what I was thinking when getting into the project. I seem to be having difficulty actually finding these motors. Texas JDM importer seems to have two but they appear over priced.

 

they need to be rebuilt. unless you get lucky these engines are 25 years old, radioactive, and have been through several hurricanes and a tsunami.

 

So what you're saying is they've been "well seasoned".

 

I would never recommend that my project be used as en example of how to build a high power 13B.

For most people, the somewhat standard build of a 13B-T, street port, big turbo, standalone, etc. is the way to go. Must of it is bolt on, well known and documented.

 

Lol that's the funniest crap I've heard in awhile on here

 

Fair enough, I was getting more at showing what went into doing a big power build in terms of supporting mods, as well as the needed creativity and fab skills to cut costs of buying a pile of parts. So I meant it to be dissuading, not persuading from the idea of a big power, low buck build.

 

Where are you planning to drift it? Come out to piedmont drift May 29 up in greensboro and hang out.

 

Dang man! I've been trying to figure out where people drift in NC. Keep me in the loop man! I can't go the 29th I have a wedding to attend-_- wife is making me haha
