Whats wrong with the B18A swap?

[QuickSilverEF9]

Won't it be harder to find a low mileage b18a though? I plan to redo the whole bottom and top ends before turbo. I am going with the F-Max setup that comes set at 9psi then I will set it to 11-14psi. I want to be up to around 240-250 horse not much higher than that. My goal is just to be able to give any import a run for its money and at least keep up with a camaro or stang.

thats what I did...bought a bare oil stricken B18a for $150. Cleaned it up and took to machine shop to get bored, honed etc...Came out brand spankin new and I still have my 97 LS in my car...no downtime at least.

[QuickSilverEF9]

So you think b18a rebuilt and with new bottom end setup would be the best bet?

Here's an old site that got me thinking of a turbo set up... http://d1profiles.tripod.com/joe.htm
Stock internals b18a with Drag 3 turbo and upgraded injectors doing 11 sec...

well, not really...If given a choice I'd go with a B20...exact same size block, head as b18a/b just bigger pistons and different intake manifold.

The b20 is a more difficult swap though.... Isnt it? What about a LS VTEC turbo? See at first I was set on ZC turbo then I found a realistic price on a b16a swap.. But I plan to go turbo and if that isn't going to be the best choice then I really need to research again. I was planning on swapping in type R pistons with a .25 overbore then adding .25 overbore sleves, forged rods (or type R rods), new head gasket and rings. Anyone know what compression the type R pistons are. They are forged so I thought the could withstand forced induction better. What do LS VTECs run in the 1/4 mile with mild mods? I might just go NA if LS VTECs can easily hit low 13s.

By the way I just saw the pictures of your car.. You got any more? HAve you decided what lip you are going to buy yet? Are we going to do a group buy? I want my lip when I finish my front conversion . I am ordering that tuesday... :hehe:. Should I expect to pay around $600 to have the conversion peices painted my rear bumper painted and my mirrors painted? What tires are you rolling on those look JDM style and go well with your car. I couldn't get away with that on mine.

B18 is a very good swap.. The only reason I went with a B16A is because its only a few hundred dollars more.. The B16 is faster and has a better tranny, but B18A in a hatch would be no slouch either.

A lot of people downtalk them because they don't come with the beloved VTEC, but then again most people saying that either have so much money they don't value the dollar, or they roll around with a D15A with an intake and exhaust and do all their racing on the internet and city streets.

Thats not always true. Theres ppl out there with high compression turbos running 11's but with low boost. You only lower the compression just to make it boost happy. If it was me i would rather have a high compression turbo then a low compression turbo. Anyways back to my other question u still haven't answered yet...why wouldn't the type r pistons fit in the b20?

[QuickSilverEF9]

Well I am impressed with the torque and results given from the b18a. I really want to thank arch5 for opening my eyes. I can save money on the swap and use it towards going turbo. Now all I have to do is find one with low milage.

Are you planning to build it up? If so then who care about finding one with low mileage. I think its cheaper to get a bare b18 block and start building it from there by replacing with aftermarket parts. Same goes with the head. Well good luck man.

B20 uses bigger diameter pistons...and type R pistons and other B-series pistons are cast and not forged, to answer another question from someone here.
And about the high compression turbo...I'm sure its possible and you're right about boosting low w/a high compression motor...but doesnt that defeat the purpose of boosting? You want to boost more for power and if you cant because of high compression, then shouldnt you build a low compression motor so you can boost it up more?:flash:

[QuickSilverEF9]

Thanks! Well I don't want to rebuild the transmission. So really all I need to do is find a low milage tranny. All b-series trannies will work right? I really want the LSD.

[EF_LSVtec]

Yes, all B-series trannies are interchangeable...and good luck finding a good cable LSD tranny...I've been searching for one in a while now too...

Ok like i said you don't have to lower your compression you can keep it stock of go a lil higher. Its all with the rite tuning and a/f . When you lower ur compression your is slow on the bottom end and when you have high compression turbo then your car will take off and have the high end power at the same time. Trust me theres guys out there EVEN with type r motor turbos running 12's on a stock bottom end.
