I want to have a projct car over the winter time or mayb later and i need some opinions. I want to turbo and iam trying to find the best engine to do so. With budget aside because iam not for sure on how much iam going to spend, which engine would be the best out of these few for around 300-350whp. It will be mostly a track car and mayb some dd on nice days but these are the engine types i was thinking of.

d16, h22, b16, or b18ls

I would like peoples experiences with these engines and would greatly appreciate it. Once again with budget aside, which one of these would be the best to obtain 300-350whp. Thanks

what no gsr? it will make 300+ pretty easily with a decent turbo

japan4racing

stock gsr, 550cc injectors, 60 trim, slicks..hav fun running low 12's...i did!

I would love to do GSR, i had one and i personally love em. I just cant find a full swap cheaper then 2k. I can get d's for extremely cheap ( iam planning on swapping this into an eg hatchback), full b16 for 1000-1200, full ls for 700 and ful h22 for around 700 altough there would be hacking and cutting if i did the h22 and i might run into clerance problems with a turbo'ed h22 into a 92-95 hatch if iam not mistakin but its going to be engine/tranny/suspention, iam really not focusing on the body all to much. But price for the full GSR swap is whats keeping me from buying cause if it breaks iam done. Thanks for the replies so far guys

japan4racing

well...you can make retarded power on really retarded torque with a d series, h22 has those damn fiber reinforced sleeves or what the hell ever they are,...i would go witht he ls. great displacment, makes good torque, and handles boost farely well. the only draw back is that you cant rev it very high. what is your budget?

McFlurry

Thats the thing, iam really not 100% sure because i have a motorcycle that needs paid off first. So depending on time the bike is paid off and how much money i can get in a short while, that will be my budget. I do however have a small current budget where all engines listed are affordable and the rest will be bought at a later date. I was thinking D series since they are extremely cheap and easy to build/come by and the LS does do well with boost (my buddy was building his to over 500hp) i still aint sure cause cheaper is better and iam thinking the LS would take less work making my hp numbers. I was wanting my internal build to only consist of pistons, mayb rods, cams, new head steads, and some mild head work done. But there is a full turbo kit used on a 450hp d16 for sale on a local website that looks mighty fine right now but i would still like opinions please.

japan4racing

if you are only going for 300-350 on a budget. get the ls, 60 trim, get tuned on 10 psi and enjoy it. on 7 psi on a 57 trim i made 260 on a gsr. 10 psi off of a 60 trim should net close to 300 i would think. and thats good for 12's

ScorpioMk

watched Leed go 10.80's in a full interior (i think) crx with a 35r gsr, stock motor just a bunch of boost and his awesome tuning. been together a while.

Well i think i have it narrowed to 2 engines. D16 and LS, so for both would mostly stock internals and massive boost be the way to reach my power desired???

japan4racing

high boost on stock internals????? i dont recomend it. but i think ls rods are stronger than d series rods. go ls just run 10 or so psi on a good tune..the tune is key here. if you get tuned you can probably run more boost...but i cant say it enough..you have to get tuned!!!!

McFlurry

Yea, i have many friends that ventured into the turbo realm only to come out with blown motors because of poor tunes. We have a few shops around here, one is slowmotion but i have some friends that are very good at tunning and have been doing so for a few years. I have seen cars fun high amounts of boost on stock internals before and i just saw a b16 with stock internals over 400hp. I was planning on beefing the internals up a bit and still debating on these two engines. I will do some more research and more posts would be appreciated on this matter. But right now i am leaning towards the D because i dont want to spend to much money because well iam cheap and i know the pick two out of cheap, reliable, and fast but iam really not that cheap. Thanks so far and expecially to japan4racing

if you want to make 300whp then i would get the b16 and a 50 trim. ls motors make decent tq but dont hold it up high to make good power. so to make 300whp on the ls, you are gonna need to push more boost and thats more stress on the bottom end.

57 trims and 60 trims are better suited for 400+whp applications, not what you are going for.

A 57 trim on an h22 works really well for 300-350hp.

PrecisionH23a

You forgot the K series option

you're right i wouldnt really go with anything less than a 57 trim on an h series. for the b series though 50 trim would be best for the 300-350whp range.

-bone stock GSR
-turbo in the 50-57 trim range
-880cc injectors
-ITR cams
-3 bar map
-E85

good for middle to upper 300whp safely....

If middle to upper 300's is "safe" than why did you cut yourself off at 315? (signature)

a few reasons actually...all of which i plan to correct this coming summer

-stock honda map sensor
-550cc injectors
-92 octane pump gas tune

When i got retuned, i just had to modify the tune on the ECU already...after i got retuned, i started seeing all the good #'s from people on E85. I guess in a sense i kind of cheaped out a little bit. I didnt want to pay for another complete retune ($400) vs fixing my existing tune ($100).

I do plan to either build my block (god willing) or snag a set of ITR cams, 880cc injectors and retune on E85 with Neptune. Either way it will be fun

lol.. I love testing people when they post numbers. Sounds like a fair answer - 400whp is the new 300whp.

McFlurry

Well i was thinking h22 but i would half to hack up a hatch a little which really wont be that big of a deal but going back to clerance issues. Would a delsol si dual core radiator be ok for this type of application the 300-350whp range or am i going to have to buy an aftermarket radiator? K is to much moeny but i would love to work on one i havent got the chance yet. Ok so far iam getting i could use a smaller trim turbo on a b16 then on a LS to get the numbers iam looking for right?

I guess one thing i have learned so far that its not very hard to acheive my goal. I have never built a turbo'ed car before and cant wait to get this started

2point2

I used a brand spankin' new civic half rad (aluminum) and had NO issues with my turbo h22. long trips, city driving, super hot days.. no issues whatsoever. I have a bottle of water wetter as well.

I think all del sol rads are dual core metal..? (my sisters was..)

Double core metal or single core full metal rads aren't as efficient as an aluminum "half rad." no matter what setup you go with you shouldnt have overheating problems living in northern ohio with a half rad. Honda didn't cut their rads in half because they're stupid..

i guess the main reason i suggested what i did was because i've seen first hand the potential of stock Honda B series engines. Not only with my 315whp (2 years running) GSR, but my buddy Mike@SLS who made 389whp on a bone stock B16 with E85. After seeing that, i am confident that you can make upper 300s on a good E85 tune without worry....if you're trying to disprove what i said earlier, i can find the graphs

No. Turbos conform to horsepower. More airflow is needed in the higher RPMs as more air is being used per unit time.

Upon the engine, I really think HT needs to quite looking at Horsepower figures as a benchmark for how much a stock block can produce. I know other cars are able to get away with this only because the torque variances between engines isn't too great. Problem is a B16 making 450whp can make the same torque as an LS making 300whp. too be realistic I think 250trq is the safe limit for all B series engines and this will equal to what I said above with the B16 vs the B18B.

Do you have a budget on how much you want to spend on the engine? The cheapest way to go would be to build a Vitara piston D series, then the Ls, then the GSR or B16 as the most expensive besides the K series or any other random engine. GL

I was posting while you wrote this, but that's exactly my point. You are looking at the same torque (which is REAL stress NOT HP) and make the assumption that all B series can handle more HP .

Like i said budget right now is not known. I have a motorcycle to pay off but it looks like i will get it paid off sooner then later so i was wanting to build something. I know you wont get much of a clue if i cant get you a price but if i need more money i save its really not that big of a deal (it is but it isnt). I have heard of the vitara D series build and i was going to help my friend build one but he has sense decided to go b20 n/a until his school is over. What turbo should i use for the D series build?
