kA vs sR vs rB??? regrets???

[FRnIsmO]

i have a ticky sohc, thinking of swapping when the engine fails, upgrading the stoppers and the stiff stuff now but i'm thinking if anyone had any regrets with their engine set ups....if you can do it all over again with the same budget, what would you do different? how much did you spend?

[statickx991]

well i have just about 13 grand into my notch top sr20det. and i regret it becuase if i had that money again for the same price as getting that motor i could have a rb25. i ran a 11.5 at 119 with a open diff and that just sucks with 13 grand into a rb i could easy have a very high horsepower motor that would be stronger. dont get me wrong i build my sr for drag racing but i have no bottom end at all and it sucks, still feels like it will break ur rib cage in the high r's around 8500 but i want that bottom end torque, buy my sr20 :-D only 5k miles on it. but in all honesty go with the rb25det it will cost around 4g to get the motor and put it in and stock my buddy ran a 12.6

[1mansho]

or you can always build a KA with forged rods pistons and people get pretty good power out of it. Should cost the same as a stock sr engine

4 gs you say??? with install......sounds like a great deal...i was thinking of the sr because its pritty much outlined until i read about lil install peevs like power steering lines, changing water pumps...idk. which shop would do the rb for that amount? that sounds too good to be tru, not that i don't believe you but i was thinking of spending more for the sR...with a install package from "fullthrottle" definately something to concider, thanks alot if i don't hear back from you

[FRnIsmO]

this would be a kade dohc right? i have a hard time looking for those....j.yard rigth? with all these sRs around, the kade sould be easy to find you'd think....i'm def. concidering them, alot of growth and respect for them lately. just read a turbo mag outlining how to build them to 750 horses. do you have a kade(t)? what do you like about it if so? how do you feel about popping the hood in a croud? not putting you down at all but just asking. personally i think they are powerful motors

[Kalypso]

If you have 5 - 7k to drop on the motor get an rb25 or better yet a 2jz.

the sr is a cost effective street beater

its not maintenance hungry its easy to reach mostly everything in a clean engine bay. water pumps are easy to change and PS lines i'v e never done but I dont think they're hard

how do you feel about popping the hood in a croud?

whatever you choose, if you work hard and follow through with it confidently you'll be proud.

If I knew I was gona drop 5-6G's I would of saved up a few more months and went LS1. I love the RB but I wouldent love an extra 200lbs. in the front a 240 that has a good 50/50 waight without a RB. For dragracing I would be all over a RB26dett like white on rice But drifting gets my rocks off!

[480sx]

Iv probably got 6 invested in my ka-t setup at this point. The reason i love ka-t so much is that i can blow motors up all day long and replace them for 350 or so. Never any parts availability problems, the aftermarket support for the KA kicks *** right now.

I also like the MPG's of the turbo 4, but if gas wasnt 4 dollars a gallon and i didnt give a fvk, i would go with the LS1 for availability and aftermarket support.

I love RB's, but they can be a huge PITA. A turbo inline 6 will always be my overall favorite engine design for raw power, and you gotta love that sound. Turbo jeep 4.0 motor in a 240 would be my dream drag car... ^^

[FRnIsmO]

i just found a turbo kit that puts 232hp and 211 lbs tq on a sohc. not many around and i can get it for 1400 with fmic and all. crazy to read but respectable power gains...cxracing.com. what do you guys think of this? maybe something to play with while i make up my mind? what will i have to do to keep my sohc alive on boost??? not that this is my fanal choice but throwing it out there....any more KadeTs out there? regrets? total invested? worst thing you ever bought? if you could do it over, what would you do?

[Kalypso]

if it doesnt have a garrett turbo dont touch it. cheap turbos are whirling shrapnel bombs.

exceptions include HKS, Greddy, KKK, holset, and borgwarner amongst other elite turbo manufaturers. but even some of them use garret internals.

you can make that kit with elite parts, for the same price. with a dash of custom fabrication

you should check out other peoples builds, you'll see a lot that you like quickly.

If i could do it over, i would go back in time and slap the **** out of myself for buying one of those kits that your thinking about buying. Out of the kit i bought that was very similar to the CRX kit with all the same main ingredients, i used some of the intercooler piping(which was hard as crap to weld because it was paper thin and full of impurities), the chinese IC, and a really cool blitz boost gage/turbo timer.

The turbo blew up in 3 WoT runs. The manifold was sold because of all the horror stories i heard about it. The couplers were complete junk, as were the BOV. The wastegate some people have had success with, but thats a really important piece of your setup. If the wastegate blows, so does your engine most of the time.

I also like the MPG's of the turbo 4, but if gas wasnt 4 dollars a gallon and i didnt give a fvk, i would go with the LS1 for availability and aftermarket support.

Those LS1s get better MPG than your Turbo 4 all day long.

FACTORY spec MPG on an LS1 with a T-56 (Borg Warner 6 Speed) gets 31 Highway.

put that in a lighter S-chassis and ditch the restrictive emissions equipment and most of the people I know who have one in stock configuration get around 34 highway.

they're also not nearly as "available" as you might think they are. I've been searching for an LS1 for the past 3 months or so and unless you're willing to pay about $6K for some hacked up hick project on ebay it's a pretty difficult hunt.... you can find them for $3-$4K but only if you're patient and check CL and other places daily.

[Kalypso]

are you still trying to do this in 2 weeks?

its possible if you do the labor yourself and order the motor today.

[FRnIsmO]

wow, thanks alot...you just saved my motor and wallet

[Kalypso]

IC piping is cheap and accessible,

in fact you can go to a muffler shop and have them bend and fab something up for you thats better quality then the cheap metal you'll find elsewhere.

I got an sr, and while I am very happy and satisfied.You can get MUCH more power out of an rb.

BUT, if its your first swap....SR all the way.I really enjoyed mine and I learned A LOT.

And, if you really want to be original(or queer) you can get a ca18.

[FRnIsmO]

most with ka's say turbo the kasr's love the sR but are ready for the rB...sohcs are still looking for a good turbo kit hehehehe

speaking of rB though, i was researching on the rB25...245 to 250hp right? after calling the shop i find out that you need an install kit, 580$ just to clear the sway bars for safe left steering, total swap going for 6800....in cali! so that's another 995 to ship it there and another 995 to get it back and that's driving it to the auto shipper and having the dude pick it up from the there and taking it to the shop to save me another 100...maybe there's a shop around nj where i'm at that i haven't found but thats a really really ruff estimate.....but its a fresh rb25!!!!alot of money....250 horses though......by the way, its from the SRstore.com they make the install kits for the rb25 and rb26 ...check it out guys and let me know

dont go rb25 if you arent planning to go over 400hp. other than that grab the rb20.

Those LS1s get better MPG than your Turbo 4 all day long.

Just did a quick google search on this. A few cars with a LS1 claim to boast a 27 or higher MPG rating, however most fall well below that. Neighborhood of 20-22 seems to be much more common. The idea of a standard v8 motor being able to beat a 4 cyl in mpgs 'all day long' is absurd. Real world pwns you. Im talking 28 mpg on average overall MPGs, your saying 32 mythical highway perfectly MPG minded driving that mostly exists in car manufacterers testing facilities/heads.

FACTORY spec MPG on an LS1 with a T-56 (Borg Warner 6 Speed) gets 31 Highway.

What the hell does this even mean? There are no MPGs assigned to a motor.. Gearing, weight, aero, and a slew of other things change MPGs on a per car basis.

put that in a lighter S-chassis and ditch the restrictive emissions equipment and most of the people I know who have one in stock configuration get around 34 highway.

Who has a LS1 swapped 240 that gets 34 highway if you dont mind me asking?

[FRnIsmO]

when they test mpg it's usually with a horse jocky driving a straight road, brand new car, perfect air pressured tires, no wind, bla bla bla....check the numbers with hybrids, always off when they should be critically acurate...LS1 lol prolly second to a Ca on mpg, those pre rBs dont give a fuQ about the earth
