Built B16a2 estimated capability

Hey guys jst done an engine swap 4 my 88 CRXsi the motor is a 93 JDM B16a2
done about 130.000 ks. iv jst had it reconditioned and dont the following so far:
how much power u think il be making and if i was going turbo hw much boost(to be safe)??? Thanks Guys

-Spoon Cams (Int-256 dur. / 11.5mm lift Exh-245 dur. / 11.1mm lift)
-Spoon Cam Gears
-Toda Valve Springs
-Crower Valves
- Toda Retainers
-stock ecu )
-LSD
-5zigen header (4-2-1)
-KOYO twin core alloy radiator
-stock bottom end
-2.5 cat back to Xforce Varex Muffler
Im currently looking at the AVO kit running a Garret GT2560R Ball Bearing.

250-300whp at 8-10psi.


Since you havent changed your internals.

Dont recommend running on stock ecu though.

hey which is the most decent ecu and value 4 money.

10PSI with a good tune, if you want to run higher your gonna need to rebuild the bottom end.

powerwise about 150-180kw atw with an avo kit (can't run that much power without a proper ECU)

hey but the avo kit comes with a piggy back ecu, that count and if i do change my eco hw much power and do i still need the piggy back..

the piggyback ECU is not that crash hot.
Radiator > oil cooler as water cooling is faster than the oil cooling.

BUt the other stuff bludger said is true, i'd get cams later. Also spoon cams are designed to be high revving N/A cams if i rem rightly. Not something recommended on a FI car.

If you can afford those items you should opt for no ECU from an AVO kit and get Hondata or PFC. The AVO kit is great for beginners but it has its limitations and is prob not the best kit out there

Neptune :thumbsup:

turbo too small so you will be limited to about 140-150 kw to the wheels as per what ievaq8 had problems with back pressure, seems your setup is more suited to a na tune rather than going the boost path.

u can still make 180kw atw with the GT28R, i've seen it on 2-3 tunes.
But if u can afford it get a GT2860RS, it will be a much nicer powerhouse

Output without turbo = 95~100kw @ wheels

Add the turbo kit with std ECU = http://lh6.ggpht.com/fisherwy/RxDbhy...est%5B2%5D.jpg

wow, that's alot of power.

DO IT.

what a good way to waste good money. If you're planing to boost, you'll be much better off doing the bottom end instead of all that cool stuff on your list, that you read off the internet.

do it right the first time man. you will save money in the long run.

I have a fully built forged bottom end B16a2 with GT2871r 56trim, 3 inch turbo back exhaust, Power FC ECU, list is endless.....

i got 235hp atw's on 10psi...i could probably get 245hp if we sat tuning it for longer, get the timing etc. But im running a low comp motor for high boost, still having fuel issues so i cant take it upto 20-24psi which im planning to...

All the head work in the list you put is unnecessary. Stock b16a2 cames are good for boost.

how much is that costing you?i would imagine to be a fare bit, is that correct?

Not as much as you'd think

All those bits with no ecu = 120-130kw IMO.......Lets no mention all the running issues you'd have in the long run. eg Blown engine etc.......

When doing a build, consult a decent mechanic to help you select your parts and possibly help with build. An programmable ecu would be very beneficial for any build project and should be on the initial shopping list.....not last! Might cost more initially, but will cost less in the long run!

This is why there are many backyard builds out there that fail because everyone who has done it has read somewhere (google generally) that they can get 80kw gain cheap and are not told that they need a rebuild in 3 months....

so how much would he be looking at? i know a mate that had issues after rain water flooded his street, it was never the same afterwards, kept going back to the guys at the tuning place

I can't give you a straight answer to that man..

There's so many different configs its not funny plus who you know for the build

with the list u have u should already be running an ECU.. why are u waiting til the turbo..+

t88+ no ecu= cold fusion

get a t88... : http://videos.streetfire.net/video/c...t88_698042.htm

Just get yourself a t3t4 .54 trim,3" dump,blox log mani,microtech ltx10,at least 440cc injecters, walbro intank,ebay fmic and pipes and NO MORE than 10psi( for longevity)and a *great fn tuner* and have fun with your 250+ there's no such thing as cheap power!

The OP said he had TODA retainers in his engine,
I just pointed out that there is no such thing.
I didn't elaborate beyond that.

Given that there is no available TODA product,
When the application required the use of such retainers, then the product from another manufacturer would obviously be used.
To make a blanket statement limiting that to one manufacturer would be incorrect.

It was a question not a blanket statment mate sorry.
Come to think of it some bloke called Adrian told me to use oem itr ones when I got my toda springs last year unless I was going to rev higher than 9 grand regularly. Nice bloke That Adrian.

Ive gotta JDM B16A2 running hondata s300 t25 rebuilt hi-flowed 160kw at 10psi all day everyday to an from work standard internals but previous owner spent heaps on the tune....

An Hi power in brisbane rekons that my civic needs a EBC to get more power out of it. I thought that sort of power would be pushing the limits of the standard internals a bit?

LOL... sorry, then the answer is yes, sometimes.

I'm not that nice either... :p

If you're just running off the wastgate spring with a bleed, there can be small gains to be had with an EBC.
But it really depends on how low the pressure of the waste gate spring is & how much boost you're losingh in the top end.
If it's not much, then that'll be what you gain.

Im running 38mm Tial wastegate 10psi spring no other sort of boost controller. It holds boost all the way to 9000rpm. Runs pretty good an can't ask much more than that. Thanks Toda.

Man....GT25 is too small, I don't know how high is the compression in your engine (9.5:1???) but probs, somewhere in 200whp, 270Nm area....How does your leak down and compression test show??

Cheap things don't go so well 90% of the time. No proper ECU limits tuning + Somewhere if you push it to 250-300whp mark + non-conservative tune = Broken ringlands, shot a rod, melted piston, lifted head etc....

hi-flowed gt25, most likely has gt28 internals if its been hi-flowed, with s300 & tune.
I don't see any issues there.

my gt2871 only does about the same on 10PSI, the numbers seem to stack up

My running a GT2871R too 9psi 161kw :thumbsup:

T3/T4 w/S300 spools great!

Dangg.. CSB

Apparently its runnig standard compression. Unsure about leak down an comp test. Was never given the dyno sheets but was there the 3rd time it was dyno'd. Probably get a retune early next year.

As far as I know an on the receipt it has had the ceramic internals changed to steel. Ported can see a bit of polished going on in there as well but is not that informing at all. Im just going on what ive been told.

Provides good power right thru the rev range spins 3rd 4th in the wet lol. Will have to take it to the next dyno day that Oz honda has in brisbane aswell should be fun..

Thanks all.

sounds like you have a pretty sweet street set up to me man i bet boost comes on nice and early but even with a flowed t25 theres not much point reving to 9k you say stock internals (10.4:1 comp b16a2) have you done any head work? 9k sounds way high for stock b16a head with stock single exhaust springs but :thumbsup::thumbsup: to the tuner.

If you want more power dont go higher on boost much 10psi with stock rods and rod bolts is a good limit think more flow.

Standard Head, thought it would hit the limiter as most cars would but it didnt an went just past 9000rpm. Did it once more to see how the boost held thought the rev range.

I know theres not much point reving that high but Ive done it now so thats that. Im not gonna spend any more money on it maybe just a dyno tune and redo the intercooler piping but that will be about it im happy with it as it is.

Guys at Hi power brisbane tuned it a couple of times Previous owner payed for that! An theyve done a great job. fuel economy $45 380kms (small tank) around town. Havent done any road trips far away yet.

i get alittle more per tank, but pretty good

i get a constant 400kms a tank in the civic with an EMS i got 670kms out of the tank on a trip once i was happy as with that :)

waste of money... put a b20 bottom end with an AFI turbo kit and your internals that you listed... 10-15psi with s300 you make good deals with AFI customer service 250-300atw

Boost > B20 thin sleeve block.

i sold him this b16a with my DA9, it's a JDM EG6 b16a and they are either supertech or crower retainers (can't really remember), the head was shaved, and i've replaced the OEM headbolts about 1.5 years ago when i installed the head, the head was in a EK9 before which pull 121kw@front wheels with C cams. (b16a head, b16b block)
