Need Help With my B18a1 Turbo build
dont flame, im new to hondas.
I have an EG
The specs on the engine are:
B18a1
t25 turbo or t3 not quite sure since it is small and says nissan on it.
je/srp pistons - Bore: 81.25mm / 3.199in - Rings: 1.0/1.2/2.8mm - Oversize: 0.01 - Stroke: 3.504 - Rod Length: 5.394 - Compression Distance: 1.181 - Head CC: 45 - Compression Ratio: 9.2:1 - Dome Volume: -5.9 - Weight: 278grams.
Eagle H-Beam Connecting Rods - Center to Center Length 5.394 - Stock Stroke - 510 Gram Weight - with ARP 2000 bolts - 1.771 crank pin, .826 piston pin and .935 b.e. width
port polish
valve retainers
valve springs
I will be using SAFC NEO to tune
What I want to know is, what else do I need to get a reliable 300rwhp on a budget?
What brand and thickness head gasket should I get?
What kind of piston rings should I get?
How much power can a stock crank hold, if less than 300rwhp what should I get?
is MSD a must?
What kind of turbo manifold should I get since the one I got cracked when I was only running 225-30 rwhp?
what else should I do?
Thanks

You need to get head studs and you need to use standalone if you want a reliable setup. 300whp will be hit easily with that setup. Easily. You'd probably be fine with the stock gasket, since your compression is going to be low. Get rings matched to your pistons..i.e. you buy JE pistons, get JE rings, you buy Wiseco pistons buy Wiseco rings. Stock cranks...assuming they are not out of round, and have been taken care of..will handle upwards of 800whp. Don't play w/ the crank. Honda ignition is completely fine until you reach the 600hp zone, then you might need to upgrade some things. Get a cast mani, it won't crack, and it can make 300whp w/ ease. Make sure you don't use that SAFC, atleast spend an extra few hundred and have yourself Hondata or something similar, like Crome, Uberdata, etc.
Fuel injectors will be very close to max if not totally maxed out...get 550cc or 660cc to give yourself some room without having injector failure.
Your pump, although I've heard can handle far more than HT believes, should be replaced since your only gonna go up in HP from here. That's a $75 investment that lives a lifetime. It's called Walbro 255lph.

Thanks. that was some great info.
Can you recommend a manifold?
also, how does this look for tuning?
Right now I have a obd-0 ecu. non-vtec head
how does crome and uber stack against hondata?

also, what kind of spark plugs should I use?
I know with bimmers you need to go 1 step colder for each 100hp
I have been loooking around and I am lost with the whole ecu thing.
can anyone help me with the whole uberdata/crome thing? I have no idea how to use it with my stock obd-0 ecu.

Your "eg" is obd0? What year is your car? It goes Hondata, Crome, Uberdata in terms of price. To me they're pretty much all the same but for you who doesn't know anything you're going to want to find a tuner who tunes one of them in your area and talk to them.
Here's a list of manifolds that are generally a decent price:
Meutek - <$200
Inline Pro - $450 (I think, maybe $500)
Custom Mani's- Anywhere from $400-800, depending upon type and brand.
(Some custom mani companies...Lovefab, Neukin, Peakboost, TT, S-fab)
Some of these mani's are lifetime warranties..such as Inline Pro, Lovefab, and Peakboost.
I assume the exotica robotic weld mani's such as Full-Race are out of the question. Regardless, they are desirable, but not for your application.
If it makes you feel better, I'm purchasing a Meutek and gonna give it a shot. I'll try to squeeze out 400whp and once I get there I will post my results, as well as my thoughts of how it is holding up, and also how hard it was to get it there.

the car is a 93 non-vtec ls b18a1.
what would I need and how would I go about installing crome or uberdata to my current ecu?
how come safc is not good to use to tune ?

I spoke to my tuner today and he said he can tune hondata, safc, greddy emanage, etc.
he said that if I was to get a safc all I would need to do is get a chip for my obd-0 to tune timing for turbo. can anyone recommend a chip for my turbo setup and where to get it?

The SAFC is not the best option, it is commonly known as the "AFC Hack" because you put big injectors in and then turn them way down to trick the map sensor, you don't want it. If the only good EMS your tuner will use is hondata then that is what you'll have to get. If the car is a 93 civic, you swapped an obd0 LS motor into your obd1 honda civic?
The "AFC Hack" will also give you NO timing retard under boost, which is why you'll never see one controlling 400whp+ and 20psi on a Honda. For OBD0 you could also run TurboEdit, which is actually free, but obviously not as good as a pay-to-play OBD1 ems.
If you want to use the AFC, you're best off leaving the motor stock and limited to ~200whp. It would be pointless to build a motor and use a hack to tune it. You do realize that the money you spend on the head (port, valves, springs/retainers) could be used to convert to obd1 AND get an EMS like Neptune or Hondata? Many people have made 350whp with a bone-stock head. Hell, there's guys that do that with STOCK SOHC heads...
For a turbo, you'll want a larger straight T3 (60 trim), and AR of probably .48 for exhaust. I can't recall what that turbo is, but if its a T3, its a 60 trim. Best way to check is to measure the exaust flange to see if its t25 or t3, then measure the small side of the compressor wheel to w/in 1/32", as its very small changes that make a big difference in power.

If you want 300whp, I would get rid of the t25 and go with a t3/t04e turbo. The 440cc injectors you have will max out right around 300-320whp. I would go with a 550cc injector to give you a little more room to grow while keeping the duty cycle of the injector down.

Thanks guys for the awesome replies.
ok, I just looked and put up an offer for a p75 chipped computer. he wants $150, doesnt that sound high since I have seen some go for around $80? what else would I need to do the obd1 conversion?
also, should I get NGK BKR7E spark plugs or something else?
I will try and stay away from the safc.

Socketing ecu's usually runs about $75-100 bucks.
Get the bcpr73s's (ngk part number 3330). They do not stick down as far in the combustion chamber as the bkr7e's do.

Thanks. I just picked up those spark plugs and also found out that my car is obd-1. What would I need to do to get my ecu converted to crome? I went to there site and all they say is that the program is free.
also, I was just doing some research on exhaust and I like the vibrant flat black exhaust, especially with the group buy going on here for $100.
My question before I order it is, should I get the 2.5" or 3" muffler?
also, should I run straight pipes from the manifold to the muffler or should I put something in between and if so what? cat, resonator?
right now my exhaust cuts off at the door on the car.

I would use stock at first. Tune the car til' it starts getting hard to find that extra horsepower...if your still not happy, then go get you some Crower Cams and a good set of timing gears to get the extra hp. You may not need those upgraded cams for your goals.
Get a 3in exhaust, it will make 300whp come alot easier. There are lots of high flow cats out there, shouldn't be an issue to choose one though.
Oh yeah...I noticed your original post you said "rwhp"...I'm sure you realize this...but Hondas are fwhp, which is a totally different animal when driving.

where can i find piston rings for these pistons locally..can i got to murrays

The engine is done and I am getting tuned with crome.
My question is how much pounds of boost should I get the car tuned for?
I will be running 11 daily and 16 when I am racing .
Thanks
