budget around 15k u want to do so many things? for honda swaps 15k is considered minimum budget only, that means buying the half cut, swapping in, doing basic maintenance and jpj approval, that's it

and dont even dream of the k20a swap because the engine alone already exceeded your budget

there's one more engine u haven't consider yet, it's the F20B, it's cheap, it's got the power u want and the dashboard looks great

Thx for the insight guys..  notworthy.gif 
But along with that, there r some questions:  tongue.gif

1) How much do b18c gsr halfcut cost?
2) madman: wat do meant by small v b16a & big v b16a? izzit SOHC & DOHC?
3) stormlcc: u mentioned on f20b, is it the bluetop ver found in accord SiR-T? whats the average price 4 it?  hmm.gif
4) Pajero 4D56: 13B-DEI or 13B-REW? & is it even possible to install them inside my hood..?  shocking.gif

and again, i apologise if my question sound very nooby-like.. & thx in advance!  biggrin.gif
*
1) RED top more than 12k, BLACK top around 10k, the price already gone sky high nowadays
2) small v is 160hp 1st gen, big v is 170hp 2nd gen
3) YES, and make sure u get the S-tronic gearbox, which looks super cool with + - gear in an old car such as yours, it used to sell RM4500 few years back, if my estimation is correct, it'll now sell around RM5-6k, which is still a bargain comparing to the overpriced B series
4) almost anything can be plugged in, however why should u, when there r so many good choices around

thanks guys for the positive responds.. I really appreciated it..  notworthy.gif

as far as the discussion goes, i think i'll go for the f20b..  nod.gif  the task now is where to find 1.. hmm.gif
but I still have 1 question though,

stormlcc: i've search around the net & could'nt find the s-tronic gearbox u mentioned.. correct me if i'm wrong, but i've only found out there is a S-Matic automatic transmission, & it comes with Accord SiR only.. plus, the engine was rated 180hp not 200hp.. the ones rated 200hp was inside Accord SiR-T (manual transmission). I've found this inside wiki though..

If this is true, which 1 should i choose? manual with 200hp, or 180hp with s-matic?  rclxub.gif
*
oh sorry, i wrote the wrong name, yes it's S-matic, not S-tronic. choosing which one depends on yourself, but i would choose the 180hp S-matic version anyday just because of the cool factor (the +- gear is just way too cool to ignore drool.gif ), and it's an auto gearbox for city driving. If u fancy a manual just go ahead, but the price might be a bit more expensive than the auto.

if the price in KL is too expensive, try other places like klang or bentong (pahang), the prices in these 2 places is much more affordable (in some shops at least)

haha.. prior to open this thread, a mechanic from a shop juz behind my hse called me & told me he found a f20b from half-cut shop at puchong area.. lolz... half-cut price told by stormlcc was spot on, around 5k+..    notworthy.gif  plus he said can choose either wan MT or AT same price.. overall cost around RM8k++... should i go for it?  hmm.gif

wow, 5k+ is a pretty good price, 8k+ is ok if it includes new timing belt and dashboard transplant, go for it and make sure u post some photos of your car after the transplant

Hi guys, i think i juz roasted my eng.. cmin back from subang, suddenly car shutdown.. stopped & smoke cmin out from the eng bay shocking.gif
I guess the car is yearning for a new eng then  sweat.gif

I met the mechanic b4 to confirm the pricing & ask him the details on the halfcut. He told me RM5700 for small v f20b NO VTEC.. if wan big v f20b w/ VTEC, hav to add 1k  doh.gif 

So, after bargaining with him;
big v F20B VTEC halfcut + wiring + dashboard + new exhaust system (extractor+2"piping+bullet silencer+muffler) + workmanship = RM9k++...  hmm.gif 
a good bargain or a rippoff?  icon_question.gif
*
i didn't know there's a f20b blue top without vtec, those without vtec ones doesn't have blue covers and is SOHC.......anyone can clarify this? about the new exhaust system, what does it include, i mean, there r so many kinds of extractors and mufflers out there (stainless steel or just steel) with lots of different brands, how much does your mechanic charge for the exhaust system alone?

and with this engine, 2.5" is the best for it, 2" is just too small, my 1.6 20valve blacktop also using 2" piping and it's restricting the air-flow a bit (even without bullet), i'm sure in a f20b it'll limit the response a lot, plus if using bullet / silencer it'll restrict much more.

u can do the exhaust system in another shop that specializes in it, that will probably set u back around 2k for the entire stainless steel + branded s-flow muffler, or 1.2k for white steel (which will rust after a couple of years) + branded muffler. If u don't want the exhaust to be too noisy, a good s-flow muffler will probably do the job, no need center bullet, it's such a waste of good power and response. but make sure u do the jpj approval for the engine first before u go do your exhaust. U can use back your original prelude exhaust for the jpj inspection, after approved, then only change it.

but any engine will perform better in lighter body wut..
like the R20A in latest accord is said to lose to civic K20Z..
if the R20A is installed on a civic probably the civic gona lose also ma XD
and ironically all big sedan are heavy so 2L might not enough, maybe thats y i felt torqueless when driving that accord euro biggrin.gif

that's why this is the best engine option in an old prelude with the best value vs performance comparison. the prelude is using a 1.8 engine, therefore if change to b16a, it's a downgrade and the price for the conversion is around RM10k for everything, it's not worth the price and the power isn't as good as the f20b. if change to b18c blacktop the price is around 12k for everything, although the power is almost the same as the f20b, the price is too much.

Found both f20b DOHC VTEC MT & AT w/ S-matic halfcut today by frens.. MT cost RM4500 while AT was RM4000..  shocking.gif

Decided to go for MT bcoz of the extra 20HP  brows.gif but the problem now is to choose the right workshop to do the swap..  sweat.gif Got several interesting offers from the local & fren recomended workshops;

1) new, small workshop located behind my hse - can kawtim within 10-14 days (worst come to worse b4 cny) - Initially, overall price around RM3000. Later, after said wan to do sumwhere else, lower price to RM1800 (w/out eng service, no new timing belt, etc.)
2) fren recommended workshop @ kg subang - said by my fren can kawtim in 3 days  shocking.gif  (worst, a week) - Price, initially 2K.. told him too expensive.. later call me back & said RM1300 (told me for the sake of frendship) doh.gif
3) father's fren workshop @ klang - said takes time but worst will be 1 month. Oso said they have done the same eng swap for the same car several years ago. Plus, the car is at his workshop for some time now bcoz owner not usin it. Give him RM1800 can kawtim d.  thumbup.gif

So which 1 is the better choice?  icon_question.gif


Anyone can give me any examples of good branded 4-2-1 extractor for f20b, where to find and the price fot it?
Modify exhaust cannot pass jpj? but my current exhaust system already rusty & broken d..  sad.gif  wat to do?
*

choosing workshop depend on whether you trust the shop or not

1) not honest, the boss should give u the exact price of the transplant, not change it when hear u going somewhere else every time.
2) not honest also, how can the price be so big a difference, but RM1300 is just so attractive, if the shop is very experienced in engine swapping then go ahead, if not, better find another honest and reliable shop
3) if it's your father's friend's shop and if it's a trusted mechanic, this is the best option, although a bit more expensive (RM1800 is considered normal price for engine and dashboard transplant) but u won't have headaches after the transplant

use back the original extractor, Honda knows what their doing, so don't bother to get other custom made extractors which will have a high chance of ruining your air flow.  If want to change, must change branded ones, but they r quite expensive.  If u want to change the exhaust system then only go inspection, install a bullet to make sure it stays 100% silent and an S-flow muffler, preferably from mugen, although it'll be a bit expensive but it's silent and efficient, after approval then get the bullet out.

I think that's the case here, coz we revved the eng both in neutral & in 1st gear oso cannot open vtec.. hmm.gif
So we'll w8 till the swap finishes & see if the problem solved by then..
1st of all, wat is lantai engine? Sry i'm a noob here, so still not fully understand some of the terms used here..  sad.gif
Secondly, yes, the nsx eng is powerfull.. but how in hell can i swap that eng under my hood  rclxub.gif  Anyway, I'm trying to make a roadworthy car here.. So a 3.0L eng is out of the question then..  shakehead.gif
*
engine lantai is obviously "an engine on the floor" icon_idea.gif means just the engine, maybe with gearbox, and maybe with wiring depends on the package and no body parts like those halfcuts

about the NSX engine, i totally LOL at the idea. I mean, yes, if u have the cash, u can do the transplant, and the project will depend on how much cash u have because there are so many things that needs to be modified to fit this engine in. And even if u got it running, the car won't be legal to run on public roads.

hahaha...nsx engine in prelude engine bay...what a joke la wei!!!

bro f20b vtec is not bad,,but f20b is not a racing type of engine..but still strong..
if u want to produce more power under ur budget,.install turbo kit at 0.7 bar..
will produce 30%-40% from original f20b horse power..
if im not mistaken,.f20b produce 150hp++ and FC 14km per 1 liter..
after install turbo kit,.f20b vtec can produce 200hp easily with stock piston,.gasket,....
and guess what,,.get ready to kick some as$!!!
*
what's the point of having a turbo kit that ruins the smoothness of the standard engine, pls note that this is a daily used car, if want a turbo engine, get a car that is more suited to a plug and play engine, like a galant vr4. plus......turbo kits with low boost sucks, 0.7 bar is nothing, just a waste of good cash
