Hello,

Below is my modification list and email from the tuner. They highly advise not to tune e85 with the stock turbo. Please help!. My goal is 400hp and reliability! Car has 128K and with 125 compression on all 4 cylinders.

Thanks


--Transmission rebuilt at Shep Racing at some point. Supposedly transmission good for 450hp.
--Front differential upgrade which can "handle a **** ton". I honestly don'tknow anything about the differential upgrade other than it cost 1k.
--HKS cams 274in, 278ex.
--Full Buschur exhaust system.
--Buschur manual boost controller tuned @21 psi, Spring replaced at 127k as old one failed.
--Walbro255 fuel pump.
--Stock turbo rebuilt at some point with a slightly larger compressor wheel.
--NGKBR7ES spark plugs.
--New single puck clutch replaced in winter of 2011. Exedy HD organic.
--New head studs.
--Short shift kit.
--EvoI X blow off valve.
--New K&N intake filter

I talked it over with our Evo tech, he said thesame thing. You're pretty much capped at where you're at. If you were to goe85, you would need a Walbro 450 fuel pump ($190), larger 1200/1300cc injectors(FID's being the cheapest Bosch EV14 option $510 ), intercooler upgrade ($640),electronic boost controller , and tune (pump + e85 or just e85?). After allthis you still run a highly likely chance of shooting a rod through the block.$1340 + electronic boost controller and tune(s)

If you really want to move forward to make power, we'd like to see you just buya turbo like a journal bearing FP red for $1100. It's not super high boost soyou don't need a ball bearing. We're okay with the intercooler kit at $640 (youwill have more money in us fabbing the piping so just stick with the kitpiping), 1000cc injectors (FID's being the cheapest Bosch EV14 option at $325),keep the manual boost controller and just do a pump gas tune. The car would besafer, make similar torque like where you're at now but move the power band upso you can make more hp up top without shooting a rod through the block. $2065+ tune.

Labor isn't added to either of these prices, but basically everyone here doesn'tfeel comfortable sending you out much higher on an e85 stock turbo and bottomend car.

 

I posted in your other thread.

You need a new tuner, that is outrageous. If he doesn't know how to keep the torque in check he doesn't need to be tuning any Evo. Ever.

Walbro 255 - $95
PTE 1000+ or equivalent - $300
Grimmspeed or MBC - $100
Tune - $350+

These are the only things needed.

 

Get bigger injectors and a new tuner. End thread

 

Pick up a set of 1,000cc injectors, find a new tuner, enjoy 40-50whp more. Be happy.

You can rummage through this directory and find a bunch of stock turbo Evos on E85:

I agree with every response in this thread. Discontinue business with your tuner. He doesn't know what he's talking about.

Thanks guys

125 compression on all cylinders, no leaks, i change the oil every 3000K, but there is 128K on a original motor. I don't want to blow up my car. I want to put about 1500-2000 into it right now.

I will have to think this one out.

 

It shouldn't cost you more than $1000 to have only the parts you need.

 

OK. Moving forward soon on the dual map e85 tune. Getting:

--VRSF 3.5 intercooler
--Injector Dynamics 1000cc injectors
--Muse lower intercooler pipe

*keeping Walbro 255 fuel pump

Tuner does recommend getting an intake through. I just have a K&N filter on the MAF with stock piping. They said get the above and we are ready to go.

 

Any car running aftermarket parts could have a chance of throwing a rod through the block if youre still on stock internals. From a business standpoint, he was correct. I feel as if your title is a little trollolol.
Search, you will see many people making close to 400hp on stock internals. Some blow, some hold. Its a chance you take for making more power then stock.

With that being said, a stock evo 9 turbo should not create enough torque to throw a rod. (Let alone an evo 8) The safe limit is 400tq with stock rods. Now have I seen one blow at that level, yes...But the numbers are limited.

In no way do I know who your tuner is or care to know. Im just stating logic...Which some people like to ignore.

BTW: Can a MOD remove his other thread? This guy thinks internet space is endless.

 

i have a BR cone filter on the stock, rubber intake and MAF. it's never given me a problem, though i'm not trying to make 400whp on a stock turbo. my turbo is a bit bigger, so i don't have to try quite as hard.
a 3.5" FMIC is maybe a bit larger than you really need, but that's fine. the LICP is, IMO a very important piece. the OEM is really crappy.

sounds like you have a solid build planned and are well on your way. not sure how reliable 400whp will be on the stock turbo would be. i see lots of people doing it, but i've never read how long it lasts. your tuner would know that one (maybe).

 

Thanks guys. Will keep you updated once I get some numbers.

Sorry for the double post. Didn't mean to offend anyone...

 

isnt PSI in your area?

 

I would be concerned with wearing your stock turbo out quickly at that power level. Might want to consider picking up a FP Green or Red to run more reliably at that power level. If you're talking DynoJet numbers, with a good tune, it should run for a long time with that setup. Good luck and keep us posted.

 

Your not going to make more power on a 255 walbro with e85. From what I read they were telling him he needs a better fuel system I agree with that. That doesnt mean there a bad shop

 

You won't max a real 255 and 1kcc injectors with a stock 10.5 turbo.
